Summary

3.6.1 update is focused mainly on improving performance and usability of existing features.

The noteable addition to the Editor is a "Log Panel", which lets you read game logs right in the editor's window. "Goto definition" now works on game object script names and opens their respective panels. Room editor features better panning and zoom controls. Views allow to select and modify multiple frames at once.

In the engine, there's a significant improvement to script performance, which may make script-heavy games run 30-40% faster compared to AGS 3.6.0 (these were real test results on a certain game with 3D simulation). There's a big improvement to the speed of manipulating Overlays, and general speed improvement of graphics rendering primarily useful for high resolution games.

There are other fixes and additions to various parts of the program too.

The full changelog follows.


What is new in 3.6.1

Common features:
- Implemented Deflate compression option for sprites.
- Removed length limits for: Game name, savegame folder, Character's script name and regular name (description), Inventory item's name (description), Mouse cursor's script name, Audioclip's script name.

Editor:
- Discontinued Source control integration functionality, removed "Put sound and sprite files in source control" option from General Settings.
- In General Settings moved few properties to different groups for better consistency.
- Added "Scale Character sprite offsets" property to General Settings. This property refers to scaling of Character.z and sprite offsets added by LockViewOffset script command.
- Added TextureCacheSize and SoundCacheSize properties to Default Setup. These let configure the sizes of runtime texture and sound cache sizes respectively.
- Added "Leave room after fade-out" event to Rooms (called "Unload" by default).
- Added Translated property to all GUI Controls (was available only in ListBox). Translated property tells whether this control's text has to be translated, and applied text direction (in right-to-left text mode).
- Support '\n' linebreak character in the Label's Text and potentially other text properties.
- Improved Room Editor controls:
    Added free panning mode done by holding the middle mouse button, or alternatively - by holding Space + LMB.
    Mouse Wheel without key modifiers scrolls the room vertically; Shift + Mouse Wheel scrolls the room horizontally.
    Zoom is done by Ctrl + Mouse Wheel and room now zooms towards or outwards the cursor position.
- In Room Editor the context menu is now displayed by RMB or Shift + RMB while editing masks.
  The individual room mode menu is merged with the "copy coordinates" command when shown.
- In Room Editor the hint with coordinates is now also displayed when moving Objects or Characters with keyboard.
- In Dialog Script editor support most Edit menu and context menu commands from the regular Script editor, with a few exceptions.
- In Sprite Manager added command "View" -> "Show filenames" which toggles display of a sprite's source filename under the sprites.
- Adjust sprites' import settings after "Crop sprite edges" command; this would ensure that these sprites are restored from source file keeping their cropped sizes.
- During sprite export Editor will display a proper progress dialog.
- Zoom controls in Character and View panes now allow downscaling too. View editor displays the preview sprite stretched to fill the parent panel.
- View editor now allows to select multiple frames at once, across multiple loops too, using standard Shift + LMB and Ctrl + LMB combinations. Properties panel lets modify properties for all the selected frames at once.
- Added "Replace with all sprites from folder" command to the View editor's context menu.
- For Audio Clips in the project tree added "Force Reimport", "Force reimport all file(s)" and "Replace Source File" context menu commands.
- For Output Panel added "Copy selection" context menu command.
- Implemented Log Panel that lets you see the engine and game logs right in the Editor.
- Improved LipSync panel looks in case user's system has display scaling option enabled.
- "Goto Definition" command in script will now work for most of the game entities too, such as Characters, GUIs, and so forth. In that case it will find a game's entity and open a respective editor panel for it. This still does not work for some types, such as Room objects, and Views.
- Added main menu commands for opening a Project folder and Compiled folder.
- Added "Export Global Messages to script" menu command. This command is meant for upgraded pre-3.2 game projects, and will generate a script with a String array, moving global messages texts there.
- For script's tabs added a context menu command for opening this script's location.
- When run with "/compile" argument Editor will print all messages to the console (stdout), instead of displaying modal message windows.
- For Android build target Editor now supports a directory to place plugins in.
- When building a game for Android and Linux the Editor will now be more tolerant to missing plugins and only issue a warning instead of stopping with error.
- Config will now be saved in UTF-8, letting to support setup program's title text in unicode.
- For non-Windows build targets Editor will fix config containing Direct3D graphics driver option and set OpenGL instead.
- For Color Themes: implemented character literal, braces match and braces error settings.
- Made Editor be somewhat more tolerate to missing XML nodes in Game.agf, in many cases it will still let open a game.
- When upgrading older game projects, Editor will insert a call to SetRestartPoint() in the end of the 'game_start' function in GlobalScript.asc. This is done to complement removal of an automatic restart point in the engine. This inserted command is safe to remove.
- When upgrading pre-3.2 rooms with disabled SaveLoadEnabled property the Editor will reset this property and insert a comment with a warning into the corresponding room's script. This is done because this property is deprecated as is no longer accessible.
- Fixed Editor refusing to open a game if one of the translation files is missing.
- Fixed General Settings and Default Setup not working correctly right after importing a pre-3.* game project.
- Fixed importing GIFs or 8-bit PNGs may lose transparent pixels if source images used other palette index than 0 for transparency.
- Fixed a warning condition for copying 32-bit bitmaps to a desktop clipboard of less color depth.
- Fixed Project Explorer's folders collapsing after certain user actions, such as dragging items or renaming things.
- Fixed a rare exception when scrolling the room in the editor.
- Fixed keyboard shortcuts for GUI Editor's Copy and Paste commands.
- Fixed deleting collapsed "region" in script would sometimes lead to portion of the script undeleted but staying invisible.
- (Possibly) Fixed a "Index out of range" exception in Script editor, related to the "script location" drop-down list, which could occur at random circumstances while working with the script, and any Color Theme is enabled.
- Fixed Editor could miss some of the files when cleaning up old compiled files after the Game's Filename property is changed.
- Fixed "Auto-number speech lines" and "Create voice acting script" operations failing if a Character's name contains underscore.

Scripting:
- Support "#else" preprocessor directive.
- Fixed escaped character literals not being parsed correctly. This makes character literals like '\n' and '\t' actually work in script.

Script API:
- Implemented Room's "After fade-out" event.
- Added eEventLeaveRoomAfterFadeout event for the global "on_event".
- Added eEventGameSaved event which runs after game was saved.
- Expanded interaction functions for Character, Object, InventoryItem, Hotspot and Region types: now they all receive respective object's pointer as a parameter, similar to GUI event functions, as well as a cursor mode this interaction was run with, if applicable.
- Added Game.ResetDoOnceOnly(), which completely resets all DoOnceOnly instances.
- Added Game.PrecacheSprite() and Game.PrecacheView(), which preload certain sprites and linked frame sounds into the engine's sprite cache memory.
- Added ScriptName property to AudioClip, Character, Dialog, GUI, GUIObject, Hotspot, InventoryItem, Object.
- Added static GetByName() function to AudioClip, Character, Dialog, GUI, GUIObject, Hotspot, InventoryItem, Object.
- Added Object.AnimationVolume property, which works similar to Character.AnimationVolume.
- Added static File.ResolvePath() and File.Path attribute.
- Added support for a text formatting to a number of functions: DisplayAtY(), Character.SayAt(), Character.SayBackground(), DrawingSurface.DrawStringWrapped().

Engine:
- Updated to SDL 2.28.5 and SDL_Sound 2.0.3+.
- Significant performance improvement to scripts. Script running speed restored to a level close to AGS 3.2.1. Testing few "script-heavy" games showed fps raise by up to 30-40% compared with 3.6.0 engine.
- Improved performance of String objects in script. For instance, appending a character to a String is now roughly x2 times faster, *sequential* iteration of String.Chars[] in Unicode mode is about x12 (!) times faster (Strings in ASCII mode have relatively less improvement, because they have been faster than Unicode mode already).
- Improved performance when creating, deleting and manipulating Overlays; allows the game to have thousands of those with much less slowing down.
- Improved performance when updating and deleting dynamic sprites, and notifying any objects that have to redraw themselves. Engine no longer resets Graphic properties of objects referencing deleted dynamic sprite to 0.
- Implemented "texture cache", in addition to the existing "sprite cache". The texture cache keeps textures generated from raw sprites and lets reusing them, improving performance and reducing CPU workload. The actual impact is proportional to the game's resolution and amount of simultaneously animated objects on screen.
- Improved OpenGL texture management, which should result in less system and video memory spent on sprite textures.
- WFN font renderer now too supports unicode mode and renders texts in utf-8, so long as the font contains glyphs of corresponding indexes.
- Buttons, ListBoxes and TextBoxes now support Right-to-left text direction.
- DrawingSurface.DrawString now supports Right-to-left text direction.
- All the script File functions now treat paths in case-insensitive way (including subdirs), which makes them platform-independent.
- Removed an automatic SetRestartPoint() call at startup. This is done in case user does not want to use default "restart" save slot, or has a custom save system.
- Support handling multiple mouse clicks per game frame, similar to how multiple key presses were supported since 3.6.0.
- When starting up, engine will now precache only first 4 or 8 loops of the starting player character's View. This is done to avoid filling sprite cache with too much sprites at once in case when the player's View contains lots of additional animations.
- Characters will now have their graphic offsets, set by Character.z property and LockViewOffset() function, scaled along with the character's own scaling. This is done so long as the respective game option is enabled in the General Settings.
- Ensure that character and object scaling is updated even when the game is not drawn. This fixes rare issues when their scale property did not update in time whilst the game was completely fadeout, and similar cases.
- Allow to change Character's move speed while its moving.
- When Character is ordered a new move command while already moving, the engine will try to make a smooth transition between old and new moving without a delay.
- Engine will now log a warning for the most incorrect parameters to Animate function instead of quitting the game.
- Engine will now skip blocking Character.Say commands instantly while skipping a cutscene.
- Object.SetView now lets invalid loop and frame values, and fallbacks to using loop 0, frame 0, printing a warning. This is also consistent with backwards-compatble SetObjectFrame() behavior.
- Changed Object.SetView() to not play a frame's sound, which could lead to a duplicated sound play if Object.Animate is run right after.
- Text Overlays internal images are now registered as dynamic sprites, and their IDs may be read from Overlay.Graphic. This lets find out their sizes using Game.SpriteWidth/SpriteHeight and optionally draw them somewhere using DrawingSurface.DrawImage.
- Ensure that when Overlays have identical ZOrder they will be sorted in the order of their creation. Besides convenience, this is also meant to restore historical behavior from before Overlay.ZOrder property was introduced.
- Allow game to call DynamicSprite.CreateFromDrawingSurface() and CreateFromBackground() with zero or negative size, clamping it to 1x1, in consistency with Create().
- Ensure all the script API is now correctly available for the plugins.
- Engine will now safeguard plugin's reading and writing of game saves, so that any mistakes done by plugins won't affect other parts of a save.
- Engine will disable vsync in a "infinite fps" mode, because vsync prevents getting more fps.
- Engine will force any in-game debug messages to be displayed in standard message boxes, disregarding game's "Display all messages as speech" option.
- Display critical alerts as message boxes on all platforms that support that (unless engine is run with "--no-message-box" parameter).
- Print some info about memory usage when reporting a "Out of memory" error.
- Deprecated in-game "console", as practically useless.
- Added new config settings in "graphics" section: "sprite_cache_size" (which replaces deprecated "cachemax" in "misc") and "texture_cache_size".
- Fixed Characters may be seemingly "walking in place" for some time when arriving at destination.
- Fixed Display and Say commands treating the second met "&" sign as a voice-over token too (they must only check the first one in string).
- Fixed PlayMP3File() function limiting filename argument by an arbitrary number of characters.
- Fixed speechlines were adjusting their Y position while trying to not overlap GUIs even when these GUIs are completely offscreen.
- Fixed first Sierra-style speechline in a sequence was adjusting its Y position without need when GUIs are set to be hidden during game pause (this includes blocking speech). Normally, the speechlines are adjusting their Y position in order to not overlap GUIs, but when GUIs are hiding during speech there should not be any need to do so.
- Fixed script behavior in case a local variable was assigned a value without being initialized with a zero memory by compiler's intruction beforehand. This is not a problem with the standard compiler, but technically could be an issue with any custom implementation.
- Fixed old-style letterbox viewport getting broken after loading an old pre-3.5.0 save.

Engine Plugin API:
- Added IAGSStream interface, IAGSEngine.OpenFileStream() and GetFileStreamByHandle().
- Added IAGSEngine.ResolveFilePath() method, which resolves a script path (with location tokens) into a proper system filepath.
- Fixed IAGSEngine.GetFontType() incorrectly reporting TTF font type for WFN fonts with more than 128 characters.

Compatibility:
- In Editor, restored all the Character's variables available in "backward-compatible" mode. This is primarily to make it easier to import very old games.
- Allow to run an animation over a loop with zero frames, by using the placeholder frame. This lets particular old games to continue running instead of crashing with error.
- Fixed slower character walking speeds in pre-3.1 upscaled and high-resolution games.
- Fixed Object.SetView() and SetObjectFrame() not treating -1 for loop and frame as "keep previous values" in older games.
- Fixed inventory window not updated after game.top_inv_item is assigned a new value.
- Fixed a "New Room" command in old-style dialog scripts was preventing "First time Enter room" event to be called.

iOS:
- Updated port for 3.6.*.

Web / Emscripten:
- Fixed Safari cannot switch the game into fullscreen mode.

Windows:
 - 32-bit Windows engine is now built as "large address aware" program, which will allow it to use up to 3 GB of RAM on 32-bit systems and 4 GB of RAM on 64-bit systems (was 2 GB previously).

WinSetup:
- Added options for setting texture cache and sound cache size.
- Added options to disable particular graphic drivers and graphic driver selection, and fullscreen mode selection.





Log Panel

We're now featuring a new Editor window called "Log Panel".



If it's not present, it may be enabled in the "Window" menu.

This panel receives log messages from the engine when running the game in a test mode (F5), and prints in the text box. This is a short-term log, it's limited by 4k messages (i think) and when hitting the limit it will clear the older ones. Its main purpose is to let users see the current and the recent state of the game.

The log settings may be configured by pressing the "Show configuration" tool button, this will make them visible to the right from the log window. The settings include 2 groups of settings:
* Log Output - lets configure the minimal level of messages that the Editor will receive. These options are only applied once the game is starting.
* Log Filter - lets configure the current (temporary) level of messages. These options may be applied anytime.

The message types are dividing between Main, Game and Script.
Main - is the main engine messages, mostly related to something important initializing or changing.
Game - are various game-related events.
Script - are messages printed by a System.Log command in script.

The Log window's font may be configured separately, in Editor Preferences, on "Advanced" tab.

Expanded interaction functions

Regarding expanded interaction functions, these are functions connected to Look at, Interact, Talk to and other similar events. They all now may have 2 parameters: a pointer to object, and cursor mode, similar to the following examples:
Code: ags
function Ego_Interact(Character *c, CursorMode mode)
function oObject1_Look(Object *o, CursorMode mode)

Exceptions:
- Hotspot WalkOn and MouseOver events do not have CursorMode parameter.
- All Region events do not have CursorMode parameter.

The purpose of this addition is to improve situation where you connect same function to multiple events and/or multiple objects at once. In such case you will be able to distinguish object and mode for which the function is actually called.

These new parameters are optional. If you don't have them declared in script, they will be ignored by the engine, and your script is going to run as before.
Also, naturally, you do not have to use them, if you don't need to (even if they are declared).

WFN fonts supporting Unicode

Engine can now draw unicode texts using WFN fonts too, if WFN fonts have appropriate letters.
Unfortunately, existing WFN editors do not let add letters at indices higher than 255. This means they need to be upgraded to allow arbitrary higher slots.
Current WFN format does not exactly have a limit to the glyph index, but it has a limit to 64k bytes of letter pixel data. This amount potentially allows it to store several alphabets in low-resolution within a single font. You may always split languages into separate fonts anyway.

Here's the modified Radiant's FontEdit which supports editing any character in range 0-65535:
https://www.dropbox.com/s/xth28bfzu78vtqi/FontEditUni.zip?dl=0
this is an "unofficial" version made purely for test.
The source project may be found here (if anyone is interested):
https://github.com/ivan-mogilko/fontedit
The example of the WFN font hosting Greek alphabet (only capitals, for test):
https://github.com/adventuregamestudio/ags/files/11540578/AGSFNT0_UNI.zip
may be tried with e.g.
Code: ags
Display("ΟΙ ΘΕΟΙ ΤΟΥ ΟΛΥΜΠΟΥ"); // THE GODS OF OLYMPUS

Summary

AGS 3.6.0 is another big change to AGS.
First of all, this release presents a SDL2-based engine. For about 2 decades AGS engine was based on Allegro 4 graphic library, which was discontinued somewhere in the early 2010-ies (only received few patches since). There was an intent to move to to Allegro 5 or SDL since, but for various reasons this task was continuously postponed. Now it's done.
Secondly the Editor and Engine now have full Unicode support. This means that you may use any language whatsoever in scripts, object descriptions and custom properties, as well as translations; so long as you also provide proper unicode fonts.
Third, we have finally expanded a list of platforms that the Editor can build for: now this includes Android and Web (Emscripten) port.

There are much more changes and improvements in this release, check out the full list of changes below.
Also, please be sure to read "Upgrading to AGS 3.6" topic in the manual: https://adventuregamestudio.github.io/ags-manual/UpgradeTo36.html



Changes in the Patch 9:

Engine:
 - Fixed engine incorrectly reporting a script loading error, which may occur if the total size of script's global variables is bigger than the size of the compiled bytecode.


Changes in the Patch 8:

Editor:
 - Fixed command "Crop sprite edges" in the Sprite Manager would copy import settings from the completely unrelated sprite onto the cropped one.

Engine:
 - Fixed `@GAMENAME@` label not updating if Game.Name property is changed at runtime.
 - Fixed System.ColorDepth was reporting a final display resolution, while it should report game's native resolution for historical reasons.

Compatibility:
 - Fixed "upscale" mode not working for "default" game resolution in pre-3.1 games (the hidden meaning of "default" is 320x200 also).

Windows:
 - Fixed a rare bug when the Windows engine could fail loading the game for no good reason.
   This error is related to a bug in Windows SDK 8.1.


Changes in the Patch 7:

Editor:
 - For Android build target disabled compression of `.ags` and `.vox` assets, as that slows down engine streaming resources (sprites etc).
 - Fixed Editor failing to start if user preferences file is corrupted
   (this is a second fix, complementing one done in AGS 3.5.1).
 - Fixed RAM use spiking fast during batch sprite reimport from sources, which could randomly lead to program errors.
 - Fixed Dialog properties displaying internal values not meant to be seen by a user.
 - Fixed selecting parent GUI after its control did not display GUI's own properties in the Properties Grid.
 - Fixed Editor generating deprecated settings in the default config file.

Engine:
 - Fixed GUI controls unexpectedly clipping parts of text even if "controls clip contents" setting is disabled, in case when their Font has VerticalOffset property set.


Changes in the Patch 6:

Editor:
- Fixed GUI editor could display selection rectangle from a different GUI editor pane, if two or more are displayed on screen at the same time.
- Fixed Script editor not marking "autoptr" and "builtin" as keywords.
- Fixed Script editor not applying color theme to character literals.
 
Engine:
- Made String.Chars and Length properties work faster in ASCII mode.
- Issue a warning when blocking Display or Say commands are called during fade-out.
- Fixed engine failing to startup sometimes if controller device subsystem failed to init (it should not init at all in this version, as we do not support joysticks yet).
- Fixed "Before fade-in" event could be called recursively under some peculiar conditions (regression since 3.6.0).
- Fixed buttons on a non-clickable GUI were still changing to "mouse over" graphic under cursor.
- Fixed button click not registered if it has been made not visible and visible again during a single game frame (regression since 3.6.0).
- Fixed TextWindow borders drawn behind the rightmost corner pieces, which may be seen if the edge sprites are half-transparent.
- Fixed a brief black screen flash occuring right after the video playback ends (regression since 3.6.0).
- Fixed engine refusing to load legacy saves if the audio clip count does not match (number of audio clips should not affect saves).
 
WinSetup:
- Added an option to disable "smooth scaled sprites" setting.
- Added an option to disable language selection.
- Made filter names in "disabled" section treated in case insensitive way.


Changes in the Patch 5:

Editor:
- Reimplemented multiple sprites properties editing in the Sprite Manager. This ability was dropped in 3.5.0 unintentionally.
- Fixed Autocomplete not treating certain struct members as "static" or "protected" if their declaration is too long.

Engine:
- Fixed Character.WalkStraight() was resetting walking animation if called during walking.
- Fixed Character's idle animation getting reset to frame 0 when the speech is played without a valid speech view (idle animation should continue playing in such case).
- Fixed idle animation sometimes not starting immediately after Character finishes walking.
- Fixed a crash occuring if script tries to get or set a custom property for a non-existing Room Object (this seem possible to do by iterating over `object[]` array).

Compatibility:
- Implemented "legacysave_assume_dataver" override option in config, which lets to instruct the engine which game data version to assume when restoring legacy (pre-3.5.0) saves. This "hack" appeared to be necessary because of a mistake done during development of the older engine versions, where the save format was changed, but engine was made to rely on the game data version instead of incrementing save format index.
- Implemented "legacysave_let_gui_diff" override option in config, which lets the engine to read less gui elements from restored save than the number registered by the game. This is to emulate a (possibly unintended) effect in pre-3.5.0 saves.
- Fixed engine could try to load game data from game.exe without checking whether data is actually appended to it when restoring a legacy save in a game with a different file structure.
- Fixed number of GUI elements were not tested when loading a legacy save, which could lead to GUI data getting overwritten incorrectly without a warning if number of controls changed since. If the test failed, engine will act according to "legacysave_let_gui_diff" config option: either quit with error or log a warning and continue.

Plugins:
- Fixed potential "index out of bounds" exceptions in the built-in PalRender plugin.

Templates:
- In "Verb Coin" template fixed action label could be updated incorrectly if the cursor was moved over buttons on any other GUI.


Changes in the Patch 4:

Editor:
- Export Game's Title into translations.
- Fixed Game.agf was not created after importing a 2.* game project (regression in 3.6.0).

Engine:
- Character.AnimationVolume property is now applied to the portrait animation as well.
- Removed few of the less important game messages from logging, because they may quickly clutter the log under some circumstances.
- Fixed when animating a character portrait, the first frame's linked sound is not played.
- Fixed IsSpeechVoxAvailable() returning positive result if run from IDE and Speech folder is empty.
- Fixed speech and messages were skipped by modifiers and other special keys (Ctrl, Alt, etc).
- Fixed crash occuring when you resize DynamicSprite while it is displayed on screen.
- Fixed audio clip started right before a ChangeRoom would not play until after the room changes.
- Fixed in Software display mode the room Overlays may not be properly covered by a walk-behind under very specific conditions.
- Fixed System.Log() would cause engine crash if there are more format placeholders than args.
- Fixed some game options that are not allowed to be changed at runtime could still be overwritten when restoring an old save, leading to a weird game behavior.


Changes in the Patch 3:

Editor:
- Don't error when loading a room file which has unsupported number of events, instead these will be cut out. This may let e.g. use room templates from newer versions of AGS.
- Sprite's default property is changed from deprecated Resolution setting to SourceFile.
- Fixed full spritefile recreation would write duplicate sprites into the spritefile, if game project (Game.agf file) contained multiple sprites with same ID for any reason (for example, if they were added by manually editing Game.agf).
- Fixed importing SCI fonts with >128 chars.
- Fixed font preview did not properly display characters with indexes 128-255.

Engine:
- Fixed "noloopcheck" script function modifier was not handled correctly sometimes.
- Fixed a button with inventory placeholder did not update immediately when the active inventory is set.
- Fixed textual GUIs were not redrawn immediately after a call to SetGameOption(OPT_RIGHTTOLEFT).


Changes in the Patch 2:

Common:
- Fixed a TTF font could cause a crash in the Editor or the Engine if the font renderer tries to draw a letter with higher number than the highest glyph number in the font.

Editor:
- Added "Restore all sprites..." command to the Sprite Manager's context menu (this duplicates the "File -> Recreate sprite file" menu command added previously).
- Refresh Sprite Manager after fully recreating a sprite file.
- Sprites will now hide their "Resolution" property if the game settings have "Allow relative asset resolutions" disabled. This is to avoid user's misuse of this property.
- Fixed a minor memory leak occuring when editing a tree item's label in Project Explorer.

Engine:
- Engine will now find and load plugins in the game dir when run from a different location.
- Fixed crash occuring if Character was told to FaceLocation while "Turn to face" game setting is enabled, and character's View does not have enough loops.
- Fixed Character resetting current non-blocking animation if it was ordered to Move, as soon as it arrives at destination.
- Fixed crash occuring if a GUI button was somehow set a negative NormalImage number.
- Fixed "bad script stack" error could be sometimes displayed if the game was aborted in the middle of running a script.


Changes in the Patch 1:

Editor:
- Fixed room's deprecated setting LegacyMusicVolumeAdjustment not applied correctly.

Engine:
- Fixed Room Objects whose dynamic sprite was deleted in "leave room" event becoming invisible during fade-out transition. Logically this has to happen, but historically they kept displaying until the transition end, so we restored this behavior for compatibility, and simply because there's no "after fade-out" event in the engine yet to delete these sprites.
- Fixed Game.StopAudio() fails to remove queued clips if no particular audio type id is requested.
- Fixed performance regression in the script related to long loops (regression in 3.6.0).
- Fixed memory leak occuring when printing text in Right-to-left mode (regression in 3.6.0).
- Fixed rare mistake during text wrapping which may occur if a Unicode text is cut in the middle of the word.
- Fixed playing certain WAVs caused game to freeze forever on exit.

Compatibility:
- Fixed frame-linked sounds not playing in the games made before 3.6.0.
- Allow game to call DynamicSprite.Create() with negative size, clamping it to 1x1.

Templates:
- In Sierra-style template fixed "mouse over" graphic for the "Load" icon.



What is new in 3.6.0

Common features:
- Full Unicode support for all game texts: game properties, scripts, translations, input.
  ASCII/ANSI mode is still working, for backwards compatibility. This may be configured in the game project.
- Extended sprite compression options: lossless storage optimization for 16- and 32-bit sprites; LZW compression option for sprites in addition to existing RLE compression.
- GUI controls may now be told to clip their contents, which means that nothing gets drawn outside of their borders (as defined by X, Y, Width, Height properties). The only exception is Sliders, which are more complicated.
- The historical TTF fonts' "fixup" that altered their height and vertical offset is now optional and works only if backwards compatible option is set.
- Max number of AudioChannels is now 16 (was 8).
- Removed game Cursors hard limit (was 20).
- Increased Room Objects limit to 256 (was 40).
- Discontinued "Windows Game Explorer" support in both Editor and Engine.

Editor:
- Editor requires .NET Framework 4.6 to run.
- Added Android build target support (requires "Android component" installed).
- Added Web/Emscripten build target support (requires "Web build component" installed).
- Expanded UI color theme format, support global color options and allow missing entries.
- Script editor works in unicode mode.
- Added "Text format" option in General Settings which lets switching between ASCII/ANSI and Unicode (UTF-8) modes. This defines which format the game texts will be written in, when saving the game project and compiling the game.
- Added "Use old-style keyboard handling" option to the General Settings, which lets select between classic key press handling and new one meant for unicode chars support in scripts.
- Supports compiling UTF-8 translations. TRS file now has "Encoding" setting that tells how to interpret this TRS text.
- Added support for building multiple speech voxes, by taking files from the Speech subfolders.
- Added support for adding custom files into the game package. This is done by assigning a list of directories to "Package custom data folder" option in General Settings.
- Editor now copies a acsetup.cfg file from the project's root folder (if one is provided by) as a base for generating default config file. Settings from Default Setup will be written over, but other found options won't be removed.
- Added "Sprite file compression" option in General Settings, replacing "Compress the sprite file" option. The new option allows a selection of compression algorithm used for sprites.
  Currently supported: None, RLE (old default compression) and LZW.
- Added "Enable sprite storage optimization" option to the General Settings, that permits the editor to repack sprites in a different storage format, reducing their disk size whenever possible. This option may be used alongside with the sprite compression. Note that this does not change how the sprites work in game.
- Added "GUI controls clip their contents" option to the General Settings.
- Added "TTF fonts height used in the game logic" option to the General Settings, that makes your game use real font's pixel height when arranging text and text-based UI elements, as opposed to the nominal font's size.
- Added "Touch to Mouse Emulation", "Touch to Mouse motion mode" and "Display FPS on Screen" to Default Setup. Removed few deprecated options.
- Added "TTF font adjustment" property to Fonts, as well as to General Settings where it serves as a project default for the new fonts. This property lets you choose between "no changes" and backward compatible TTF fixup meant to keep fonts made for AGS displayed as they were meant to.
- In the "Import TTF" dialog added a choice to import the size closest to the given pixel height.
- Fonts now have Auto Outline Style and Auto Outline Thickness properties.
- Fonts now have a readonly Family Name field, that lets user see the original name of a font they've imported (if available).
- Added IdleDelay property to Characters that lets you set time needed to pass before IdleView is activated. This is equivalent to the Character.SetIdleView script function.
- Added Character.IdleAnimationDelay property to let setup idle view's animation speed.
- Added Cursor.AnimationDelay property to let setup cursor's animation speed.
- The TextWindow edges now have distinct names in the dropdown list of the property grid.
- Rooms created from a Blank template will now have default background of a game's resolution.
- When creating new room objects they will now have their script names set to some default value.
- Added Room.BackgroundAnimationEnabled property to let have disabled animation on room load.
- Editor will now create an empty sprite file if one is missing in the game project. Any existing sprite descriptions in the project will be kept, letting user to reimport these from sources.
- Added "File -> Restore all sprites from sources" menu command.
- Added "Apply" button on editor's Preferences dialog.
- In Preferences replaced "Import Color Theme" with a "Open Theme Folder", as a temporary solution for managing theme files.
- Select script editor's font in the editor's Preferences.
- Added "Help" option to the editor pane's tab context menu.
- Upgraded script editor to Scintilla 3.21.1 and ScintillaNET 3.6.3.
- Cursor's position in script is now displayed on the status bar.
- Dialog scripts now too can open help topics for keywords or script functions under cursor on F1.
- Added zoom controls for the Sprite Manager, Character, Cursor, Inventory and View panes.
- Sprites may now be imported by drag'n'drop into the Sprite manager.
- In sprite manager's context menu added command "Create source files for all sprites with missing / external sources..."
- In sprite manager's context menu added (restored) command "Replace sprite using previous files".
  Also made "previous file" remembered consistently whenever a sprite is imported or replaced.
- In sprite manager's "export all" dialog added "skip if inside project's folder" option.
- In sprite manager's "export all" dialog added "reset tile settings" option.
- On the View pane the frames having set delay and linked sound will be now indicated with icons.
- Editor no longer errors and fails when opening a game project with some script files missing.
- Editor no longer errors on empty translations when compiling the game.
- Editor now exports values of the string type Custom Properties to translations.
- Editor no longer prevents exporting string arguments from Get/SetTextProperty calls to TRS file.
- Editor now cleanups spritefile on game load, identifying any data not referenced by the project and marking it for deletion.
- Fixed editor silently enabling all available Build Targets when upgrading a pre-3.4.0 project. This could be very inconvenient as there are several of them supported now.
- Fixed open folders in the Project Tree were collapsing whenever you create a new subfolder or change an object's name in properties.
- Fixed editor was not preventing from entering Character's and AudioClip's ScriptName too long for the engine to handle.
- Fixed Image and View properties in various objects were allowing negative values.
- Fixed some of the object previews (at least GUI) could crash if user entered a non-existing sprite's number as an Image property.
- Fixed editor displaying unhandled exception if the script which user is trying to open was missing. Instead it will now open a blank script.
- Fixed room editor was suggesting to save the modified room even if no changes were made.
- Fixed a recently imported sprite could be displayed incorrectly scaled up in the room editor for high-resolution games, if the "Allow relative asset resolutions" was enabled in General Settings, and the sprite 0 had "Resolution" property set to "Low".
- Fixed program crash occuring on sprite's import if failed to open a source file for any reason.
- Fixed View animation preview stopping at frame 100 (if loop contains over 100 frames).
- Fixed going to a "find all" result in dialog script did not highlight the found text, and sometimes did not scroll down to it.
- Fixed "Goto Definition" not working for Enums and Defines (macros).
- Fixed script autocomplete sometimes was not updated right after opening a script.
- Fixed script autocomplete for function calls was mistreating commas in strings and inline comments as if they were separating actual parameters.
- Fixed script autocomplete was not displaying members of extended structs if the parent struct was declared in another header.
- Fixed script autocomplete was not working for enum names.

- Fixed few editor panes were not opening correct help topics in F1.
- (Possibly) fixed error message text in the runtime error popup could be drawn partially beyond the popup borders if the user's system has text scaling option enabled.

Compiler:
- Support unicode character literals.
- Support using float literals when defining default values for function arguments.
- Support hexadecimal number literals (e.g. "0xABCDEF").
- Removed 500-characters line limit.

Script API:
- Expanded `on_key_press` callback, now supports two parameters: key code and key modifier flags.
- In the new key handling mode `on_key_press` is called for each actual key press;
  e.g. combinations like Ctrl+Z will result in two `on_key_press` calls, one with eKeyCtrlLeft and second with eKeyZ; added support for "NEW_KEYINPUT_API" macro in scripts.
- Implemented new `on_text_input(int ch)` callback which is called when the engine receives a printable character. This callback is essential for handling unicode chars in script.
- Similarily, expanded `dialog_options_key_press` with the third `mod` argument, and implemented `dialog_options_text_input` callback for receiving unicode chars during the custom dialog options state.
- Implemented `dialog_options_close` callback which is called when custom dialog options are removed from the screen. This allows to perform any required cleanup.
- Added eEventEnterRoomAfterFadein event for `on_event` callback, which corresponds to "enter after fade-in" room event.
- Added eKey constants for Shift, Control and Alt keys.
- Added eKeyMod enum for key modifiers constants.
- String.AppendChar(), ReplaceChar() functions and String.Chars[] property are now working with the unicode characters.
- String.Format("%c") specifier will now be able to print unicode characters.
- Extended Button.Animate() to have blocking style, direction and starting frame parameters, thus matching other Animate commands (of Character and Object).
- Extended all Animate() commands by adding "volume" parameter, that defines volume of the frame-linked sounds for the duration of this animation.
- Added Character.AnimationVolume, defining volume of the frame-linked sounds.
- Added Character.IdleAnimationDelay to let control idle view's animation speed.
- Character.Scaling is no longer limited by a range of 5-200 (now supports 1-32767).
- Hotspot.Name and Object.Name may now be set in script.
- Added Object.ManualScaling and Object.Scaling.
- Deprecated Object.IgnoreScaling (use Object.ManualScaling instead).
- Object.SetView default loop & frame values are now 0 (was -1 which retained loop and frame indexes from the previous view, often unexpected to the user).
- DrawingSurface.DrawImage() and DrawSurface() now support optional source rect coordinates.
- Added functions for getting DrawingSurface of room masks: GetDrawingSurfaceForWalkableArea(), GetDrawingSurfaceForWalkbehind(), Hotspot.GetDrawingSurface(), Region.GetDrawingSurface().
- Added new delay parameter to Mouse.ChangeModeView() to let control cursor's animation speed.
- Added Game.ChangeSpeechVox() and Game.SpeechVoxFilename, support switching the voice-over pack.
- Added Mouse.AutoLock property that toggles automatic mouse lock inside the game window.
- Added Room.Exists().
- Added System.Log().
- Added SkipWait() that skips any active Wait() function.
- Added WaitMouse() to complement existing Wait functions.
- Added InputType enum which defines input devices and lets create their sets as flags.
- Added WaitInput(), a more generic and extendable function that accepts a combination of flags telling which input types to wait for.
- All Wait* functions now may have infinite timeout if you pass a negative timeout parameter.
- All Wait* functions now return the reason they were skipped: a combination of InputType flag and a respective key or button code.
- Added GUIControl.Transparency property.
- Added Overlay.CreateRoomGraphical and CreateRoomTextual. Use these two functions to create "room overlays": that is - overlays that display a sprite inside the room, sorted among other room objects, characters and walk-behinds.
- Added readonly Overlay.InRoom property that tells if this is a room or screen overlay.
- Extended Overlay.CreateGraphical() with a new "clone" parameter that tells whether to assign a sprite index, or make a sprite's copy owned exclusively by this overlay. The former will save program memory but make overlay update if the sprite is edited later. The latter is meant primarily for backwards compatibility.
  Overlay.CreateRoomGraphical has the same param.
- Added Overlay.Graphic property that lets you change overlay's sprite after it's created.
- Added Overlay.Width and Height properties, that let you freely scale existing Overlay.
- Added readonly Overlay.GraphicWidth and GraphicHeight properties that let read original overlay's graphic size, as not all overlays hold a sprite reference (e.g. textual overlays).
- Added Overlay.Transparency property.
- Added Overlay.ZOrder property that lets you sort Overlays among themselves and other objects in the same "game layer": screen overlays are sorted among GUI, while room overlays are sorted among room objects, characters and walk-behinds.
- Added Speech.TextOverlay and Speech.PortraitOverlay for accessing blocking speech overlay and portrait overlay respectively.
- Added Game.BlockingWaitSkipped which tells the result of the last blocking wait skipping, also including result of the blocking speech skipping.
- SkipSpeechStyle now supports eSkipNone mode; when used it will disable any kind of skipping, such speech can be only skipped by a direct command from script.
- Extended Screen.ScreenToRoomPoint() with an optional "restrictToViewport" argument, which lets to choose whether tests over empty place result in conversion through the default viewport or a null pointer.
- Added AudioClip.PlayOnChannel().
- Added AudioChannel.Pause() and Resume() functions, and IsPaused property.
- Added AudioChannel.SeekMs(), complementing PositionMs (as the Seek() function interprets position differently depending on the audio format).
- PlayVideo() now supports an option to play both game's and video's audio track simultaneously.
- Added File.WriteRawInt() to complement ReadRawInt().
- File paths in script now support $DATA$ token, which tells to read files from the game package. This only works for read operations. Functions that support this token currently are:
  File.Open(), DynamicSprite.CreateFromFile(), ListBox.FillDirList().
- Debug(2, 0) command that displayed walkable areas is superceded by Debug(2, n), where "n" is a mask type: 0 - none, 1 - hotspots, 2 - walkbehinds, 3 - walkable areas, 4 - regions. This command also works as a toggle switch, calling it with the same mask index will turn it off.
- Debug(5, n) command that displayed character's walk paths now also works as a toggle switch.

Engine:
- New SDL2-based backend for graphics, audio and input.
- Hqx graphic filters discontinued (could be temporary).
- Windows-only DirectMedia video playback discontinued (could be temporary).
  Only OGG/OGV videos are kept supported at this point.
- Support resizing game window on desktop systems.
- Support "borderless full-screen window" mode in addition to the real (exclusive) fullscreen.
- Support for switching vertical sync at runtime with Direct3D/OpenGL renderers. Also enable vsync in windowed mode too.
- Unicode (UTF-8) text support: engine can now switch between ASCII and UTF-8 text mode. This is controlled by both game's OPT_GAMETEXTENCODING setting and translation's "Encoding" setting: they tells whether to interpret game texts as UTF-8 or ASCII/ANSI.
- Support optional translation's "GameEncoding" setting: it hints the original game's codepage to help with their conversion. This is mostly meant for translating existing older (ANSI) games.
- Engine now supports using real pixel height of the TTF fonts when arranging text and UI elements on screen; using nominal import size of the font is used as a compatible mode for the old games.
- Also supports separate "normal" and backward compatible "fixup" modes when initializing TTF fonts, letting to display both common TTFs and ones made specifically for AGS in the past to display as they were meant to be.
- Supports scripts using functions and variables from any other scripts, regardless of the script module order in the project.
- Removed limit of simultaneous Button animations.
- Removed limit of Character followers.
- Removed Overlay limit.
- Character.SetWalkSpeed() is no longer restricted by an arbitrary limit of 50.
- Process character's idle view based on real game speed, not hardcoded 40 fps.
- Improved file writing times (e.g. when doing a game save) by using buffered file stream. Initial tests showed 50% faster file writing.
- Engine now renders GUI controls as separate textures when using hardware accelerated renderers. This may significantly improve performance in the high-resolution games and games with large number of GUI elements on screen.
- Engine now shares the video texture data for all game objects on screen sharing same sprite. This improves performance in case there are multiple objects which use same image.
- Various performance optimizations for both raw drawing and texture updates (Direct3D/OpenGL).
- Engine now ensures that in threaded audio mode the AudioChannel's state only changes once the game is updated, and not while the game script is running. This prevents situations when the clip could begin playing before all properties are set in script, or when AudioChannel's properties' values (such as Position) could change while running a game script.
- 24-bit wav PCM support, comes with the new sound library.
- File.ReadRawLineBack() now always reads full line, and not limited to 200 characters anymore.
- Debug displays, such as showing room mask and character walk paths, are now implemented as non-blocking translucent overlays, allowing you to keep playing the game while they are on.
- Implemented debug key controls for calling a built-in save and restore game dialogs. These controls have to be set in user config as "save_game_key" and "restore_game_key" in "[override]" category. These may be used by testers if the game is missing a save function or one is bugged.
- Engine now supports loading compiled scripts as separate files packed along with the game, along with those embedded into the main game data or inside room files.
- Engine no longer bails out with error if the chosen translation cannot be loaded on startup.
- When reporting script errors, engine will print callstack for all the active script "threads": for example, if there's Wait() function called and error happened in repeatedly_execute_always, then it will print both actual error's location, and Wait() call's location.
- Engine config now has graphic modes defined as a simplier string options: "[graphics] fullscreen" for the fullscreen mode setup, and "[graphics] window" for the windowed.
  Fullscreen option can explicitly define a "borderless full-screen window" mode.
- Added "emul_mouse_mode" and "emul_mouse_relative" options to config in "[touch]" category.
- Added "cache_size" and "stream_threshold" options to config in "[sound]" category, they setup the rules for sound caching and choosing whether to load a clip fully into mem or stream one.
- Added "load_latest_save" and "show_fps" options to config in "[misc]" category.
- Added "background" option to config in "[misc]" category, that defines the starting run-in-background (aka multitasking) mode (may later be changed by SetMultitaskingMode()).
  Added "--background" command line option for the same purpose.
- Added "--sdl-log" command line option for setting up SDL2 library output verbosity. The engine log config now has a new "sdl" group meant for SDL2 messages.
- Support "--user-conf-dir" command-line arg (and "user_conf_dir" config option) superceding "--localuserconf"; the new option directly tells the location of user config file.
- Path related command-line and config options, - such as "shared_data_dir", "user_data_dir" and "user_conf_dir", now support $GAMENAME$ token in path which is resolved to the game's title.
- Added "--clear-cache-on-room-change" command-line arg (and similar config option).
- Don't error when DrawingSurface.DrawImage has bad transparency parameter (warning instead).
- Don't error when detecting bad format in File.Read* functions (warning instead).
- Added stubs for agsshell plugin (a contemporary cross-platform variant of ags_shell).
- Added stubs for agsappopenurl plugin.
- Fixed potential crashes if a room-related API function has been called in "game_start"; this is achieved by having a dummy room placeholder object. Still results of such calls are undefined and should not be relied upon.
- Fixed potential crash on room load if the walkable area mask contained color values above the supported range.
- Fixed dialog script's "goto-previous" command not working if used from the first sub-topic run using "goto-dialog" (a very-very old bug).
- Fixed AGS_EngineInitGfx plugin callback was not called during OpenGL renderer initialization.
- Fixed Direct3D/OpenGL renderers were displaying plugin's raw drawings in a wrong position in the scrolling rooms, if the drawing was done on AGSE_PRESCREENDRAW or AGSE_POSTROOMDRAW events.
- Fixed overlay may fail to be created sometimes, if previously another overlay had been forcefully removed when changing rooms (this is an ancient bug which existed for many years).
- Fixed ListBox.RowCount reporting 0 if called before the control was displayed once.
- Fixed GetTextWidth would still return a size of an outline for an empty text string.
- Fixed text may be misaligned in gui controls, as its outline thickness is not counted.
- Fixed some TTF fonts could be cut at the bottom when the speech is displayed.
- Fixed scheduled sound fadeout effect was not cancelled by skipping a cutscene.
- Fixed OGV Theora videos positioned incorrectly if they have certain sizes or aspect ratios.
- Fixed game fps sped up if SetGameSpeed() is called repeatedly in game script.
- Fixed game not reacting to system close commands when stuck in script, which made it impossible
  to close the "hanging" game by usual means (other than terminating the process).

Engine Plugin API:
- Added IAGSEngine::GetGameInfo() function which returns information about the game, such as its title and GUID.
- Added new render callback AGSE_POSTROOMDRAW, for handling drawing inside the room above all room objects.
- Added IAGSFontRenderer2 interface, expanding the original font renderer interface, improving font plugins support.
- Added ReplaceFontRenderer2() and NotifyFontUpdated() functions.

Compatibility:
- Fallback to the first loop with frames if current character's loop does not have any.
- Use the dummy frame if current character's speech view loop does not have any.
- Ignore character having view/loop with no frames while it's not in the current room.
- Legacy behavior of MoveCharacterBlocking's return value.
- Fixed walkable area's continuous scaling was broken for high-res rooms in old games.
- In pre-3.* games force player to walkable area after changing rooms, this is to emulate an unintentional effect created by the old engines.
- Fixed pre-3.4.1 anti-aliased TTF fonts display (their vertical position was broken).
- For pre-3.5.0 games support old behavior of coincidental dynamic sprite replacement on GUI backgrounds (and few other places) without explicit assignment; that is - when the new DynamicSprite is created right after deleting an old one.
- Support Label.TextAlignment with legacy alignment constants for pre-3.5.0 games made with the custom engine from "Clifftop Games".
- Support native resolution hack for games made with "Clifftop Games" custom engine, where 640x400 games are run as 640x360.

Android:
- Rewrote universal AGS game launcher/player using up-to-date Google guidelines. The former "launcher" is now called "AGS Player".
- Implemented single game project template meant for building your own signed APK.
- Implemented two touch-to-mouse control scheme (selectable in config), for one finger emulating LMB only, and for two fingers emulating LMB and RMB.
- Support relative motion speed setting for touch-to-mouse emulation.
- In AGS Player added "Browse" button to the game folder selection, which opens default system file picker.
- AGS Player now searches for games recursively, in all the subfolders.
- AGS Player now has preference button per each game, which opens individual game's settings.

OSX:
- OpenGL renderer is now supported on MacOS.

Web / Emscripten:
- Initial port release.

Windows:
- Installer will create program links with three-digit version in the name.

Plugins:
- Added SpriteFont plugin to the list of builtins, for ports that use ones.
  SpriteFont plugin is updated to support custom "Clifftop Games" font variants.

WinSetup:
- Added "Fullscreen as borderless window" checkbox.
- Remade sound options to reflect the move to the new audio system in the engine.




Known issues

* Although Unicode text is supported overall, some languages may still not be printed correctly automatically. Firstly, those that require "letter linking", such as Arabic or Persian, do not have the proper linking on its own. This may be worked around using special text converters and fonts. Another issue is that texts printed right-to-left in the source (where print direction is done using Unicode's control characters) are not wrapped correctly and may require manual placement of line breaks, or scripting their split in game.
* MIDI no longer plays on its own on Windows. For MIDI you (and your players) must install "sound banks" (also known as "sound font"). Please refer to this article: https://adventuregamestudio.github.io/ags-manual/MIDI-playback.html
* AudioChannel.Position and AudioChannel.Seek do not work for MIDI and MOD sounds. Try sticking to PositionMs and SeekMs for now.
* There are reports about Direct3D not being able to restore the fullscreen mode after alt+tabbing occasionaly.





Thanks to everyone who contributed to and tested this version!



#43
Someone pointed me out to this, the AGS Licensing page has been outdated for a while now.

https://www.adventuregamestudio.co.uk/site/ags/legal/

Large parts of it about used libraries are no longer matching starting with 3.6.0.
However there are also smaller bits that are probably not relevant for decades... like the bit about "default font ripped from Sierra games".

For the reference, this is the copyright page in the manual now:
https://github.com/adventuregamestudio/ags-manual/wiki/Copyright

On a side note, I could not find how exactly do you get to this "legal" page from the main page...

Summary

AGS 3.6.0 is another big change to AGS.
First of all, this release presents a SDL2-based engine. For about 2 decades AGS engine was based on Allegro 4 graphic library, which was discontinued somewhere in the early 2010-ies (only received few patches since). There was an intent to move to to Allegro 5 or SDL since, but for various reasons this task was continuously postponed. Now it's done.
Secondly the Editor and Engine now have full Unicode support. This means that you may use any language whatsoever in scripts, object descriptions and custom properties, as well as translations; so long as you also provide proper unicode fonts.
Third, we have finally expanded a list of platforms that the Editor can build for: now this includes Android and Web (Emscripten) port.

There are much more changes and improvements in this release, check out the full list of changes below.
Also, please be sure to read "Upgrading to AGS 3.6" topic in the manual: https://adventuregamestudio.github.io/ags-manual/UpgradeTo36.html



Changes in the Patch 7:

Editor:
 - For Android build target disabled compression of `.ags` and `.vox` assets, as that slows down engine streaming resources (sprites etc).
 - Fixed Editor failing to start if user preferences file is corrupted
   (this is a second fix, complementing one done in AGS 3.5.1).
 - Fixed RAM use spiking fast during batch sprite reimport from sources, which could randomly lead to program errors.
 - Fixed Dialog properties displaying internal values not meant to be seen by a user.
 - Fixed selecting parent GUI after its control did not display GUI's own properties in the Properties Grid.
 - Fixed Editor generating deprecated settings in the default config file.

Engine:
 - Fixed GUI controls unexpectedly clipping parts of text even if "controls clip contents" setting is disabled, in case when their Font has VerticalOffset property set.


Changes in the Patch 6:

Editor:
- Fixed GUI editor could display selection rectangle from a different GUI editor pane, if two or more are displayed on screen at the same time.
- Fixed Script editor not marking "autoptr" and "builtin" as keywords.
- Fixed Script editor not applying color theme to character literals.
 
Engine:
- Made String.Chars and Length properties work faster in ASCII mode.
- Issue a warning when blocking Display or Say commands are called during fade-out.
- Fixed engine failing to startup sometimes if controller device subsystem failed to init (it should not init at all in this version, as we do not support joysticks yet).
- Fixed "Before fade-in" event could be called recursively under some peculiar conditions (regression since 3.6.0).
- Fixed buttons on a non-clickable GUI were still changing to "mouse over" graphic under cursor.
- Fixed button click not registered if it has been made not visible and visible again during a single game frame (regression since 3.6.0).
- Fixed TextWindow borders drawn behind the rightmost corner pieces, which may be seen if the edge sprites are half-transparent.
- Fixed a brief black screen flash occuring right after the video playback ends (regression since 3.6.0).
- Fixed engine refusing to load legacy saves if the audio clip count does not match (number of audio clips should not affect saves).
 
WinSetup:
- Added an option to disable "smooth scaled sprites" setting.
- Added an option to disable language selection.
- Made filter names in "disabled" section treated in case insensitive way.


Changes in the Patch 5:

Editor:
- Reimplemented multiple sprites properties editing in the Sprite Manager. This ability was dropped in 3.5.0 unintentionally.
- Fixed Autocomplete not treating certain struct members as "static" or "protected" if their declaration is too long.

Engine:
- Fixed Character.WalkStraight() was resetting walking animation if called during walking.
- Fixed Character's idle animation getting reset to frame 0 when the speech is played without a valid speech view (idle animation should continue playing in such case).
- Fixed idle animation sometimes not starting immediately after Character finishes walking.
- Fixed a crash occuring if script tries to get or set a custom property for a non-existing Room Object (this seem possible to do by iterating over `object[]` array).

Compatibility:
- Implemented "legacysave_assume_dataver" override option in config, which lets to instruct the engine which game data version to assume when restoring legacy (pre-3.5.0) saves. This "hack" appeared to be necessary because of a mistake done during development of the older engine versions, where the save format was changed, but engine was made to rely on the game data version instead of incrementing save format index.
- Implemented "legacysave_let_gui_diff" override option in config, which lets the engine to read less gui elements from restored save than the number registered by the game. This is to emulate a (possibly unintended) effect in pre-3.5.0 saves.
- Fixed engine could try to load game data from game.exe without checking whether data is actually appended to it when restoring a legacy save in a game with a different file structure.
- Fixed number of GUI elements were not tested when loading a legacy save, which could lead to GUI data getting overwritten incorrectly without a warning if number of controls changed since. If the test failed, engine will act according to "legacysave_let_gui_diff" config option: either quit with error or log a warning and continue.

Plugins:
- Fixed potential "index out of bounds" exceptions in the built-in PalRender plugin.

Templates:
- In "Verb Coin" template fixed action label could be updated incorrectly if the cursor was moved over buttons on any other GUI.


Changes in the Patch 4:

Editor:
- Export Game's Title into translations.
- Fixed Game.agf was not created after importing a 2.* game project (regression in 3.6.0).

Engine:
- Character.AnimationVolume property is now applied to the portrait animation as well.
- Removed few of the less important game messages from logging, because they may quickly clutter the log under some circumstances.
- Fixed when animating a character portrait, the first frame's linked sound is not played.
- Fixed IsSpeechVoxAvailable() returning positive result if run from IDE and Speech folder is empty.
- Fixed speech and messages were skipped by modifiers and other special keys (Ctrl, Alt, etc).
- Fixed crash occuring when you resize DynamicSprite while it is displayed on screen.
- Fixed audio clip started right before a ChangeRoom would not play until after the room changes.
- Fixed in Software display mode the room Overlays may not be properly covered by a walk-behind under very specific conditions.
- Fixed System.Log() would cause engine crash if there are more format placeholders than args.
- Fixed some game options that are not allowed to be changed at runtime could still be overwritten when restoring an old save, leading to a weird game behavior.


Changes in the Patch 3:

Editor:
- Don't error when loading a room file which has unsupported number of events, instead these will be cut out. This may let e.g. use room templates from newer versions of AGS.
- Sprite's default property is changed from deprecated Resolution setting to SourceFile.
- Fixed full spritefile recreation would write duplicate sprites into the spritefile, if game project (Game.agf file) contained multiple sprites with same ID for any reason (for example, if they were added by manually editing Game.agf).
- Fixed importing SCI fonts with >128 chars.
- Fixed font preview did not properly display characters with indexes 128-255.

Engine:
- Fixed "noloopcheck" script function modifier was not handled correctly sometimes.
- Fixed a button with inventory placeholder did not update immediately when the active inventory is set.
- Fixed textual GUIs were not redrawn immediately after a call to SetGameOption(OPT_RIGHTTOLEFT).


Changes in the Patch 2:

Common:
- Fixed a TTF font could cause a crash in the Editor or the Engine if the font renderer tries to draw a letter with higher number than the highest glyph number in the font.

Editor:
- Added "Restore all sprites..." command to the Sprite Manager's context menu (this duplicates the "File -> Recreate sprite file" menu command added previously).
- Refresh Sprite Manager after fully recreating a sprite file.
- Sprites will now hide their "Resolution" property if the game settings have "Allow relative asset resolutions" disabled. This is to avoid user's misuse of this property.
- Fixed a minor memory leak occuring when editing a tree item's label in Project Explorer.

Engine:
- Engine will now find and load plugins in the game dir when run from a different location.
- Fixed crash occuring if Character was told to FaceLocation while "Turn to face" game setting is enabled, and character's View does not have enough loops.
- Fixed Character resetting current non-blocking animation if it was ordered to Move, as soon as it arrives at destination.
- Fixed crash occuring if a GUI button was somehow set a negative NormalImage number.
- Fixed "bad script stack" error could be sometimes displayed if the game was aborted in the middle of running a script.


Changes in the Patch 1:

Editor:
- Fixed room's deprecated setting LegacyMusicVolumeAdjustment not applied correctly.

Engine:
- Fixed Room Objects whose dynamic sprite was deleted in "leave room" event becoming invisible during fade-out transition. Logically this has to happen, but historically they kept displaying until the transition end, so we restored this behavior for compatibility, and simply because there's no "after fade-out" event in the engine yet to delete these sprites.
- Fixed Game.StopAudio() fails to remove queued clips if no particular audio type id is requested.
- Fixed performance regression in the script related to long loops (regression in 3.6.0).
- Fixed memory leak occuring when printing text in Right-to-left mode (regression in 3.6.0).
- Fixed rare mistake during text wrapping which may occur if a Unicode text is cut in the middle of the word.
- Fixed playing certain WAVs caused game to freeze forever on exit.

Compatibility:
- Fixed frame-linked sounds not playing in the games made before 3.6.0.
- Allow game to call DynamicSprite.Create() with negative size, clamping it to 1x1.

Templates:
- In Sierra-style template fixed "mouse over" graphic for the "Load" icon.



What is new in 3.6.0

Common features:
- Full Unicode support for all game texts: game properties, scripts, translations, input.
  ASCII/ANSI mode is still working, for backwards compatibility. This may be configured in the game project.
- Extended sprite compression options: lossless storage optimization for 16- and 32-bit sprites; LZW compression option for sprites in addition to existing RLE compression.
- GUI controls may now be told to clip their contents, which means that nothing gets drawn outside of their borders (as defined by X, Y, Width, Height properties). The only exception is Sliders, which are more complicated.
- The historical TTF fonts' "fixup" that altered their height and vertical offset is now optional and works only if backwards compatible option is set.
- Max number of AudioChannels is now 16 (was 8).
- Removed game Cursors hard limit (was 20).
- Increased Room Objects limit to 256 (was 40).
- Discontinued "Windows Game Explorer" support in both Editor and Engine.

Editor:
- Editor requires .NET Framework 4.6 to run.
- Added Android build target support (requires "Android component" installed).
- Added Web/Emscripten build target support (requires "Web build component" installed).
- Expanded UI color theme format, support global color options and allow missing entries.
- Script editor works in unicode mode.
- Added "Text format" option in General Settings which lets switching between ASCII/ANSI and Unicode (UTF-8) modes. This defines which format the game texts will be written in, when saving the game project and compiling the game.
- Added "Use old-style keyboard handling" option to the General Settings, which lets select between classic key press handling and new one meant for unicode chars support in scripts.
- Supports compiling UTF-8 translations. TRS file now has "Encoding" setting that tells how to interpret this TRS text.
- Added support for building multiple speech voxes, by taking files from the Speech subfolders.
- Added support for adding custom files into the game package. This is done by assigning a list of directories to "Package custom data folder" option in General Settings.
- Editor now copies a acsetup.cfg file from the project's root folder (if one is provided by) as a base for generating default config file. Settings from Default Setup will be written over, but other found options won't be removed.
- Added "Sprite file compression" option in General Settings, replacing "Compress the sprite file" option. The new option allows a selection of compression algorithm used for sprites.
  Currently supported: None, RLE (old default compression) and LZW.
- Added "Enable sprite storage optimization" option to the General Settings, that permits the editor to repack sprites in a different storage format, reducing their disk size whenever possible. This option may be used alongside with the sprite compression. Note that this does not change how the sprites work in game.
- Added "GUI controls clip their contents" option to the General Settings.
- Added "TTF fonts height used in the game logic" option to the General Settings, that makes your game use real font's pixel height when arranging text and text-based UI elements, as opposed to the nominal font's size.
- Added "Touch to Mouse Emulation", "Touch to Mouse motion mode" and "Display FPS on Screen" to Default Setup. Removed few deprecated options.
- Added "TTF font adjustment" property to Fonts, as well as to General Settings where it serves as a project default for the new fonts. This property lets you choose between "no changes" and backward compatible TTF fixup meant to keep fonts made for AGS displayed as they were meant to.
- In the "Import TTF" dialog added a choice to import the size closest to the given pixel height.
- Fonts now have Auto Outline Style and Auto Outline Thickness properties.
- Fonts now have a readonly Family Name field, that lets user see the original name of a font they've imported (if available).
- Added IdleDelay property to Characters that lets you set time needed to pass before IdleView is activated. This is equivalent to the Character.SetIdleView script function.
- Added Character.IdleAnimationDelay property to let setup idle view's animation speed.
- Added Cursor.AnimationDelay property to let setup cursor's animation speed.
- The TextWindow edges now have distinct names in the dropdown list of the property grid.
- Rooms created from a Blank template will now have default background of a game's resolution.
- When creating new room objects they will now have their script names set to some default value.
- Added Room.BackgroundAnimationEnabled property to let have disabled animation on room load.
- Editor will now create an empty sprite file if one is missing in the game project. Any existing sprite descriptions in the project will be kept, letting user to reimport these from sources.
- Added "File -> Restore all sprites from sources" menu command.
- Added "Apply" button on editor's Preferences dialog.
- In Preferences replaced "Import Color Theme" with a "Open Theme Folder", as a temporary solution for managing theme files.
- Select script editor's font in the editor's Preferences.
- Added "Help" option to the editor pane's tab context menu.
- Upgraded script editor to Scintilla 3.21.1 and ScintillaNET 3.6.3.
- Cursor's position in script is now displayed on the status bar.
- Dialog scripts now too can open help topics for keywords or script functions under cursor on F1.
- Added zoom controls for the Sprite Manager, Character, Cursor, Inventory and View panes.
- Sprites may now be imported by drag'n'drop into the Sprite manager.
- In sprite manager's context menu added command "Create source files for all sprites with missing / external sources..."
- In sprite manager's context menu added (restored) command "Replace sprite using previous files".
  Also made "previous file" remembered consistently whenever a sprite is imported or replaced.
- In sprite manager's "export all" dialog added "skip if inside project's folder" option.
- In sprite manager's "export all" dialog added "reset tile settings" option.
- On the View pane the frames having set delay and linked sound will be now indicated with icons.
- Editor no longer errors and fails when opening a game project with some script files missing.
- Editor no longer errors on empty translations when compiling the game.
- Editor now exports values of the string type Custom Properties to translations.
- Editor no longer prevents exporting string arguments from Get/SetTextProperty calls to TRS file.
- Editor now cleanups spritefile on game load, identifying any data not referenced by the project and marking it for deletion.
- Fixed editor silently enabling all available Build Targets when upgrading a pre-3.4.0 project. This could be very inconvenient as there are several of them supported now.
- Fixed open folders in the Project Tree were collapsing whenever you create a new subfolder or change an object's name in properties.
- Fixed editor was not preventing from entering Character's and AudioClip's ScriptName too long for the engine to handle.
- Fixed Image and View properties in various objects were allowing negative values.
- Fixed some of the object previews (at least GUI) could crash if user entered a non-existing sprite's number as an Image property.
- Fixed editor displaying unhandled exception if the script which user is trying to open was missing. Instead it will now open a blank script.
- Fixed room editor was suggesting to save the modified room even if no changes were made.
- Fixed a recently imported sprite could be displayed incorrectly scaled up in the room editor for high-resolution games, if the "Allow relative asset resolutions" was enabled in General Settings, and the sprite 0 had "Resolution" property set to "Low".
- Fixed program crash occuring on sprite's import if failed to open a source file for any reason.
- Fixed View animation preview stopping at frame 100 (if loop contains over 100 frames).
- Fixed going to a "find all" result in dialog script did not highlight the found text, and sometimes did not scroll down to it.
- Fixed "Goto Definition" not working for Enums and Defines (macros).
- Fixed script autocomplete sometimes was not updated right after opening a script.
- Fixed script autocomplete for function calls was mistreating commas in strings and inline comments as if they were separating actual parameters.
- Fixed script autocomplete was not displaying members of extended structs if the parent struct was declared in another header.
- Fixed script autocomplete was not working for enum names.
- Fixed structs and enums were not highlighted if declared inside a script's body.
- Fixed in dialogs numbers inside names were incorrectly highlighted as numeric values.
- Fixed matching or mismatching braces were not highlighted consistently at all times in regular and dialog scripts.
- Fixed crash occuring when user was trying to set breakpoint on the very last line in script.
- Fixed few editor panes were not opening correct help topics in F1.
- (Possibly) fixed error message text in the runtime error popup could be drawn partially beyond the popup borders if the user's system has text scaling option enabled.

Compiler:
- Support unicode character literals.
- Support using float literals when defining default values for function arguments.
- Support hexadecimal number literals (e.g. "0xABCDEF").
- Removed 500-characters line limit.

Script API:
- Expanded `on_key_press` callback, now supports two parameters: key code and key modifier flags.
- In the new key handling mode `on_key_press` is called for each actual key press;
  e.g. combinations like Ctrl+Z will result in two `on_key_press` calls, one with eKeyCtrlLeft and second with eKeyZ; added support for "NEW_KEYINPUT_API" macro in scripts.
- Implemented new `on_text_input(int ch)` callback which is called when the engine receives a printable character. This callback is essential for handling unicode chars in script.
- Similarily, expanded `dialog_options_key_press` with the third `mod` argument, and implemented `dialog_options_text_input` callback for receiving unicode chars during the custom dialog options state.
- Implemented `dialog_options_close` callback which is called when custom dialog options are removed from the screen. This allows to perform any required cleanup.
- Added eEventEnterRoomAfterFadein event for `on_event` callback, which corresponds to "enter after fade-in" room event.
- Added eKey constants for Shift, Control and Alt keys.
- Added eKeyMod enum for key modifiers constants.
- String.AppendChar(), ReplaceChar() functions and String.Chars[] property are now working with the unicode characters.
- String.Format("%c") specifier will now be able to print unicode characters.
- Extended Button.Animate() to have blocking style, direction and starting frame parameters, thus matching other Animate commands (of Character and Object).
- Extended all Animate() commands by adding "volume" parameter, that defines volume of the frame-linked sounds for the duration of this animation.
- Added Character.AnimationVolume, defining volume of the frame-linked sounds.
- Added Character.IdleAnimationDelay to let control idle view's animation speed.
- Character.Scaling is no longer limited by a range of 5-200 (now supports 1-32767).
- Hotspot.Name and Object.Name may now be set in script.
- Added Object.ManualScaling and Object.Scaling.
- Deprecated Object.IgnoreScaling (use Object.ManualScaling instead).
- Object.SetView default loop & frame values are now 0 (was -1 which retained loop and frame indexes from the previous view, often unexpected to the user).
- DrawingSurface.DrawImage() and DrawSurface() now support optional source rect coordinates.
- Added functions for getting DrawingSurface of room masks: GetDrawingSurfaceForWalkableArea(), GetDrawingSurfaceForWalkbehind(), Hotspot.GetDrawingSurface(), Region.GetDrawingSurface().
- Added new delay parameter to Mouse.ChangeModeView() to let control cursor's animation speed.
- Added Game.ChangeSpeechVox() and Game.SpeechVoxFilename, support switching the voice-over pack.
- Added Mouse.AutoLock property that toggles automatic mouse lock inside the game window.
- Added Room.Exists().
- Added System.Log().
- Added SkipWait() that skips any active Wait() function.
- Added WaitMouse() to complement existing Wait functions.
- Added InputType enum which defines input devices and lets create their sets as flags.
- Added WaitInput(), a more generic and extendable function that accepts a combination of flags telling which input types to wait for.
- All Wait* functions now may have infinite timeout if you pass a negative timeout parameter.
- All Wait* functions now return the reason they were skipped: a combination of InputType flag and a respective key or button code.
- Added GUIControl.Transparency property.
- Added Overlay.CreateRoomGraphical and CreateRoomTextual. Use these two functions to create "room overlays": that is - overlays that display a sprite inside the room, sorted among other room objects, characters and walk-behinds.
- Added readonly Overlay.InRoom property that tells if this is a room or screen overlay.
- Extended Overlay.CreateGraphical() with a new "clone" parameter that tells whether to assign a sprite index, or make a sprite's copy owned exclusively by this overlay. The former will save program memory but make overlay update if the sprite is edited later. The latter is meant primarily for backwards compatibility.
  Overlay.CreateRoomGraphical has the same param.
- Added Overlay.Graphic property that lets you change overlay's sprite after it's created.
- Added Overlay.Width and Height properties, that let you freely scale existing Overlay.
- Added readonly Overlay.GraphicWidth and GraphicHeight properties that let read original overlay's graphic size, as not all overlays hold a sprite reference (e.g. textual overlays).
- Added Overlay.Transparency property.
- Added Overlay.ZOrder property that lets you sort Overlays among themselves and other objects in the same "game layer": screen overlays are sorted among GUI, while room overlays are sorted among room objects, characters and walk-behinds.
- Added Speech.TextOverlay and Speech.PortraitOverlay for accessing blocking speech overlay and portrait overlay respectively.
- Added Game.BlockingWaitSkipped which tells the result of the last blocking wait skipping, also including result of the blocking speech skipping.
- SkipSpeechStyle now supports eSkipNone mode; when used it will disable any kind of skipping, such speech can be only skipped by a direct command from script.
- Extended Screen.ScreenToRoomPoint() with an optional "restrictToViewport" argument, which lets to choose whether tests over empty place result in conversion through the default viewport or a null pointer.
- Added AudioClip.PlayOnChannel().
- Added AudioChannel.Pause() and Resume() functions, and IsPaused property.
- Added AudioChannel.SeekMs(), complementing PositionMs (as the Seek() function interprets position differently depending on the audio format).
- PlayVideo() now supports an option to play both game's and video's audio track simultaneously.
- Added File.WriteRawInt() to complement ReadRawInt().
- File paths in script now support $DATA$ token, which tells to read files from the game package. This only works for read operations. Functions that support this token currently are:
  File.Open(), DynamicSprite.CreateFromFile(), ListBox.FillDirList().
- Debug(2, 0) command that displayed walkable areas is superceded by Debug(2, n), where "n" is a mask type: 0 - none, 1 - hotspots, 2 - walkbehinds, 3 - walkable areas, 4 - regions. This command also works as a toggle switch, calling it with the same mask index will turn it off.
- Debug(5, n) command that displayed character's walk paths now also works as a toggle switch.

Engine:
- New SDL2-based backend for graphics, audio and input.
- Hqx graphic filters discontinued (could be temporary).
- Windows-only DirectMedia video playback discontinued (could be temporary).
  Only OGG/OGV videos are kept supported at this point.
- Support resizing game window on desktop systems.
- Support "borderless full-screen window" mode in addition to the real (exclusive) fullscreen.
- Support for switching vertical sync at runtime with Direct3D/OpenGL renderers. Also enable vsync in windowed mode too.
- Unicode (UTF-8) text support: engine can now switch between ASCII and UTF-8 text mode. This is controlled by both game's OPT_GAMETEXTENCODING setting and translation's "Encoding" setting: they tells whether to interpret game texts as UTF-8 or ASCII/ANSI.
- Support optional translation's "GameEncoding" setting: it hints the original game's codepage to help with their conversion. This is mostly meant for translating existing older (ANSI) games.
- Engine now supports using real pixel height of the TTF fonts when arranging text and UI elements on screen; using nominal import size of the font is used as a compatible mode for the old games.
- Also supports separate "normal" and backward compatible "fixup" modes when initializing TTF fonts, letting to display both common TTFs and ones made specifically for AGS in the past to display as they were meant to be.
- Supports scripts using functions and variables from any other scripts, regardless of the script module order in the project.
- Removed limit of simultaneous Button animations.
- Removed limit of Character followers.
- Removed Overlay limit.
- Character.SetWalkSpeed() is no longer restricted by an arbitrary limit of 50.
- Process character's idle view based on real game speed, not hardcoded 40 fps.
- Improved file writing times (e.g. when doing a game save) by using buffered file stream. Initial tests showed 50% faster file writing.
- Engine now renders GUI controls as separate textures when using hardware accelerated renderers. This may significantly improve performance in the high-resolution games and games with large number of GUI elements on screen.
- Engine now shares the video texture data for all game objects on screen sharing same sprite. This improves performance in case there are multiple objects which use same image.
- Various performance optimizations for both raw drawing and texture updates (Direct3D/OpenGL).
- Engine now ensures that in threaded audio mode the AudioChannel's state only changes once the game is updated, and not while the game script is running. This prevents situations when the clip could begin playing before all properties are set in script, or when AudioChannel's properties' values (such as Position) could change while running a game script.
- 24-bit wav PCM support, comes with the new sound library.
- File.ReadRawLineBack() now always reads full line, and not limited to 200 characters anymore.
- Debug displays, such as showing room mask and character walk paths, are now implemented as non-blocking translucent overlays, allowing you to keep playing the game while they are on.
- Implemented debug key controls for calling a built-in save and restore game dialogs. These controls have to be set in user config as "save_game_key" and "restore_game_key" in "[override]" category. These may be used by testers if the game is missing a save function or one is bugged.
- Engine now supports loading compiled scripts as separate files packed along with the game, along with those embedded into the main game data or inside room files.
- Engine no longer bails out with error if the chosen translation cannot be loaded on startup.
- When reporting script errors, engine will print callstack for all the active script "threads": for example, if there's Wait() function called and error happened in repeatedly_execute_always, then it will print both actual error's location, and Wait() call's location.
- Engine config now has graphic modes defined as a simplier string options: "[graphics] fullscreen" for the fullscreen mode setup, and "[graphics] window" for the windowed.
  Fullscreen option can explicitly define a "borderless full-screen window" mode.
- Added "emul_mouse_mode" and "emul_mouse_relative" options to config in "[touch]" category.
- Added "cache_size" and "stream_threshold" options to config in "[sound]" category, they setup the rules for sound caching and choosing whether to load a clip fully into mem or stream one.
- Added "load_latest_save" and "show_fps" options to config in "[misc]" category.
- Added "background" option to config in "[misc]" category, that defines the starting run-in-background (aka multitasking) mode (may later be changed by SetMultitaskingMode()).
  Added "--background" command line option for the same purpose.
- Added "--sdl-log" command line option for setting up SDL2 library output verbosity. The engine log config now has a new "sdl" group meant for SDL2 messages.
- Support "--user-conf-dir" command-line arg (and "user_conf_dir" config option) superceding "--localuserconf"; the new option directly tells the location of user config file.
- Path related command-line and config options, - such as "shared_data_dir", "user_data_dir" and "user_conf_dir", now support $GAMENAME$ token in path which is resolved to the game's title.
- Added "--clear-cache-on-room-change" command-line arg (and similar config option).
- Don't error when DrawingSurface.DrawImage has bad transparency parameter (warning instead).
- Don't error when detecting bad format in File.Read* functions (warning instead).
- Added stubs for agsshell plugin (a contemporary cross-platform variant of ags_shell).
- Added stubs for agsappopenurl plugin.
- Fixed potential crashes if a room-related API function has been called in "game_start"; this is achieved by having a dummy room placeholder object. Still results of such calls are undefined and should not be relied upon.
- Fixed potential crash on room load if the walkable area mask contained color values above the supported range.
- Fixed dialog script's "goto-previous" command not working if used from the first sub-topic run using "goto-dialog" (a very-very old bug).
- Fixed AGS_EngineInitGfx plugin callback was not called during OpenGL renderer initialization.
- Fixed Direct3D/OpenGL renderers were displaying plugin's raw drawings in a wrong position in the scrolling rooms, if the drawing was done on AGSE_PRESCREENDRAW or AGSE_POSTROOMDRAW events.
- Fixed overlay may fail to be created sometimes, if previously another overlay had been forcefully removed when changing rooms (this is an ancient bug which existed for many years).
- Fixed ListBox.RowCount reporting 0 if called before the control was displayed once.
- Fixed GetTextWidth would still return a size of an outline for an empty text string.
- Fixed text may be misaligned in gui controls, as its outline thickness is not counted.
- Fixed some TTF fonts could be cut at the bottom when the speech is displayed.
- Fixed scheduled sound fadeout effect was not cancelled by skipping a cutscene.
- Fixed OGV Theora videos positioned incorrectly if they have certain sizes or aspect ratios.
- Fixed game fps sped up if SetGameSpeed() is called repeatedly in game script.
- Fixed game not reacting to system close commands when stuck in script, which made it impossible
  to close the "hanging" game by usual means (other than terminating the process).

Engine Plugin API:
- Added IAGSEngine::GetGameInfo() function which returns information about the game, such as its title and GUID.
- Added new render callback AGSE_POSTROOMDRAW, for handling drawing inside the room above all room objects.
- Added IAGSFontRenderer2 interface, expanding the original font renderer interface, improving font plugins support.
- Added ReplaceFontRenderer2() and NotifyFontUpdated() functions.

Compatibility:
- Fallback to the first loop with frames if current character's loop does not have any.
- Use the dummy frame if current character's speech view loop does not have any.
- Ignore character having view/loop with no frames while it's not in the current room.
- Legacy behavior of MoveCharacterBlocking's return value.
- Fixed walkable area's continuous scaling was broken for high-res rooms in old games.
- In pre-3.* games force player to walkable area after changing rooms, this is to emulate an unintentional effect created by the old engines.
- Fixed pre-3.4.1 anti-aliased TTF fonts display (their vertical position was broken).
- For pre-3.5.0 games support old behavior of coincidental dynamic sprite replacement on GUI backgrounds (and few other places) without explicit assignment; that is - when the new DynamicSprite is created right after deleting an old one.
- Support Label.TextAlignment with legacy alignment constants for pre-3.5.0 games made with the custom engine from "Clifftop Games".
- Support native resolution hack for games made with "Clifftop Games" custom engine, where 640x400 games are run as 640x360.

Android:
- Rewrote universal AGS game launcher/player using up-to-date Google guidelines. The former "launcher" is now called "AGS Player".
- Implemented single game project template meant for building your own signed APK.
- Implemented two touch-to-mouse control scheme (selectable in config), for one finger emulating LMB only, and for two fingers emulating LMB and RMB.
- Support relative motion speed setting for touch-to-mouse emulation.
- In AGS Player added "Browse" button to the game folder selection, which opens default system file picker.
- AGS Player now searches for games recursively, in all the subfolders.
- AGS Player now has preference button per each game, which opens individual game's settings.

OSX:
- OpenGL renderer is now supported on MacOS.

Web / Emscripten:
- Initial port release.

Windows:
- Installer will create program links with three-digit version in the name.

Plugins:
- Added SpriteFont plugin to the list of builtins, for ports that use ones.
  SpriteFont plugin is updated to support custom "Clifftop Games" font variants.

WinSetup:
- Added "Fullscreen as borderless window" checkbox.
- Remade sound options to reflect the move to the new audio system in the engine.




Known issues

* Although Unicode text is supported overall, some languages may still not be printed correctly automatically. Firstly, those that require "letter linking", such as Arabic or Persian, do not have the proper linking on its own. This may be worked around using special text converters and fonts. Another issue is that texts printed right-to-left in the source (where print direction is done using Unicode's control characters) are not wrapped correctly and may require manual placement of line breaks, or scripting their split in game.
* MIDI no longer plays on its own on Windows. For MIDI you (and your players) must install "sound banks" (also known as "sound font"). Please refer to this article: https://adventuregamestudio.github.io/ags-manual/MIDI-playback.html
* AudioChannel.Position and AudioChannel.Seek do not work for MIDI and MOD sounds. Try sticking to PositionMs and SeekMs for now.
* There are reports about Direct3D not being able to restore the fullscreen mode after alt+tabbing occasionaly.





Thanks to everyone who contributed to and tested this version!



#45
A while ago selmiak has requested that when objects and characters are moved by keyboard in the room editor, the editor would also display their coordinates, similar to how they are displayed when being dragged by a mouse.
https://github.com/adventuregamestudio/ags/issues/984

I tried to make this work with a small change
https://github.com/adventuregamestudio/ags/pull/2229

But that immediately raised a question of when to hide this extra label with coordinates on them.

The problem is, when you move with a mouse the hint may stay for as long as the mouse button is down.
But with keyboard, when arrow is down the object will keep moving. User may want to stop for a while to think, or check something. If I make the hint disappear in this moment, then user will have to hit an arrow once again to make it reappear, but will move object away from its location at the same time. This makes things uncomfortable, and I am concerned that this will defeat the purpose of the fix.

There are following options that came to mind (there may be others which i missed):
1. Make coordinates display all the time so long as object is selected;
2. Keep coordinates display after it's been moved by keys until it's moved by mouse or deselected;
3. Hide this hint by a timer run after user released the moving keys (but then some users may argue that timeout is not enough).

I cannot decide, so post here to ask for opinions.
Option 1) is the simpliest, but I wonder if users won't like how it looks like.


If you like to see how this works,
there's a temp build with this feature (3.6.1 based): https://cirrus-ci.com/task/6302126616346624

Summary

AGS 3.6.0 is another big change to AGS.
First of all, this release presents a SDL2-based engine. For about 2 decades AGS engine was based on Allegro 4 graphic library, which was discontinued somewhere in the early 2010-ies (only received few patches since). There was an intent to move to to Allegro 5 or SDL since, but for various reasons this task was continuously postponed. Now it's done.
Secondly the Editor and Engine now have full Unicode support. This means that you may use any language whatsoever in scripts, object descriptions and custom properties, as well as translations; so long as you also provide proper unicode fonts.
Third, we have finally expanded a list of platforms that the Editor can build for: now this includes Android and Web (Emscripten) port.

There are much more changes and improvements in this release, check out the full list of changes below.
Also, please be sure to read "Upgrading to AGS 3.6" topic in the manual: https://adventuregamestudio.github.io/ags-manual/UpgradeTo36.html



Changes in the Patch 6:

Editor:
- Fixed GUI editor could display selection rectangle from a different GUI editor pane, if two or more are displayed on screen at the same time.
- Fixed Script editor not marking "autoptr" and "builtin" as keywords.
- Fixed Script editor not applying color theme to character literals.
 
Engine:
- Made String.Chars and Length properties work faster in ASCII mode.
- Issue a warning when blocking Display or Say commands are called during fade-out.
- Fixed engine failing to startup sometimes if controller device subsystem failed to init (it should not init at all in this version, as we do not support joysticks yet).
- Fixed "Before fade-in" event could be called recursively under some peculiar conditions (regression since 3.6.0).
- Fixed buttons on a non-clickable GUI were still changing to "mouse over" graphic under cursor.
- Fixed button click not registered if it has been made not visible and visible again during a single game frame (regression since 3.6.0).
- Fixed TextWindow borders drawn behind the rightmost corner pieces, which may be seen if the edge sprites are half-transparent.
- Fixed a brief black screen flash occuring right after the video playback ends (regression since 3.6.0).
- Fixed engine refusing to load legacy saves if the audio clip count does not match (number of audio clips should not affect saves).
 
WinSetup:
- Added an option to disable "smooth scaled sprites" setting.
- Added an option to disable language selection.
- Made filter names in "disabled" section treated in case insensitive way.


Changes in the Patch 5:

Editor:
- Reimplemented multiple sprites properties editing in the Sprite Manager. This ability was dropped in 3.5.0 unintentionally.
- Fixed Autocomplete not treating certain struct members as "static" or "protected" if their declaration is too long.

Engine:
- Fixed Character.WalkStraight() was resetting walking animation if called during walking.
- Fixed Character's idle animation getting reset to frame 0 when the speech is played without a valid speech view (idle animation should continue playing in such case).
- Fixed idle animation sometimes not starting immediately after Character finishes walking.
- Fixed a crash occuring if script tries to get or set a custom property for a non-existing Room Object (this seem possible to do by iterating over `object[]` array).

Compatibility:
- Implemented "legacysave_assume_dataver" override option in config, which lets to instruct the engine which game data version to assume when restoring legacy (pre-3.5.0) saves. This "hack" appeared to be necessary because of a mistake done during development of the older engine versions, where the save format was changed, but engine was made to rely on the game data version instead of incrementing save format index.
- Implemented "legacysave_let_gui_diff" override option in config, which lets the engine to read less gui elements from restored save than the number registered by the game. This is to emulate a (possibly unintended) effect in pre-3.5.0 saves.
- Fixed engine could try to load game data from game.exe without checking whether data is actually appended to it when restoring a legacy save in a game with a different file structure.
- Fixed number of GUI elements were not tested when loading a legacy save, which could lead to GUI data getting overwritten incorrectly without a warning if number of controls changed since. If the test failed, engine will act according to "legacysave_let_gui_diff" config option: either quit with error or log a warning and continue.

Plugins:
- Fixed potential "index out of bounds" exceptions in the built-in PalRender plugin.

Templates:
- In "Verb Coin" template fixed action label could be updated incorrectly if the cursor was moved over buttons on any other GUI.


Changes in the Patch 4:

Editor:
- Export Game's Title into translations.
- Fixed Game.agf was not created after importing a 2.* game project (regression in 3.6.0).

Engine:
- Character.AnimationVolume property is now applied to the portrait animation as well.
- Removed few of the less important game messages from logging, because they may quickly clutter the log under some circumstances.
- Fixed when animating a character portrait, the first frame's linked sound is not played.
- Fixed IsSpeechVoxAvailable() returning positive result if run from IDE and Speech folder is empty.
- Fixed speech and messages were skipped by modifiers and other special keys (Ctrl, Alt, etc).
- Fixed crash occuring when you resize DynamicSprite while it is displayed on screen.
- Fixed audio clip started right before a ChangeRoom would not play until after the room changes.
- Fixed in Software display mode the room Overlays may not be properly covered by a walk-behind under very specific conditions.
- Fixed System.Log() would cause engine crash if there are more format placeholders than args.
- Fixed some game options that are not allowed to be changed at runtime could still be overwritten when restoring an old save, leading to a weird game behavior.


Changes in the Patch 3:

Editor:
- Don't error when loading a room file which has unsupported number of events, instead these will be cut out. This may let e.g. use room templates from newer versions of AGS.
- Sprite's default property is changed from deprecated Resolution setting to SourceFile.
- Fixed full spritefile recreation would write duplicate sprites into the spritefile, if game project (Game.agf file) contained multiple sprites with same ID for any reason (for example, if they were added by manually editing Game.agf).
- Fixed importing SCI fonts with >128 chars.
- Fixed font preview did not properly display characters with indexes 128-255.

Engine:
- Fixed "noloopcheck" script function modifier was not handled correctly sometimes.
- Fixed a button with inventory placeholder did not update immediately when the active inventory is set.
- Fixed textual GUIs were not redrawn immediately after a call to SetGameOption(OPT_RIGHTTOLEFT).


Changes in the Patch 2:

Common:
- Fixed a TTF font could cause a crash in the Editor or the Engine if the font renderer tries to draw a letter with higher number than the highest glyph number in the font.

Editor:
- Added "Restore all sprites..." command to the Sprite Manager's context menu (this duplicates the "File -> Recreate sprite file" menu command added previously).
- Refresh Sprite Manager after fully recreating a sprite file.
- Sprites will now hide their "Resolution" property if the game settings have "Allow relative asset resolutions" disabled. This is to avoid user's misuse of this property.
- Fixed a minor memory leak occuring when editing a tree item's label in Project Explorer.

Engine:
- Engine will now find and load plugins in the game dir when run from a different location.
- Fixed crash occuring if Character was told to FaceLocation while "Turn to face" game setting is enabled, and character's View does not have enough loops.
- Fixed Character resetting current non-blocking animation if it was ordered to Move, as soon as it arrives at destination.
- Fixed crash occuring if a GUI button was somehow set a negative NormalImage number.
- Fixed "bad script stack" error could be sometimes displayed if the game was aborted in the middle of running a script.


Changes in the Patch 1:

Editor:
- Fixed room's deprecated setting LegacyMusicVolumeAdjustment not applied correctly.

Engine:
- Fixed Room Objects whose dynamic sprite was deleted in "leave room" event becoming invisible during fade-out transition. Logically this has to happen, but historically they kept displaying until the transition end, so we restored this behavior for compatibility, and simply because there's no "after fade-out" event in the engine yet to delete these sprites.
- Fixed Game.StopAudio() fails to remove queued clips if no particular audio type id is requested.
- Fixed performance regression in the script related to long loops (regression in 3.6.0).
- Fixed memory leak occuring when printing text in Right-to-left mode (regression in 3.6.0).
- Fixed rare mistake during text wrapping which may occur if a Unicode text is cut in the middle of the word.
- Fixed playing certain WAVs caused game to freeze forever on exit.

Compatibility:
- Fixed frame-linked sounds not playing in the games made before 3.6.0.
- Allow game to call DynamicSprite.Create() with negative size, clamping it to 1x1.

Templates:
- In Sierra-style template fixed "mouse over" graphic for the "Load" icon.



What is new in 3.6.0

Common features:
- Full Unicode support for all game texts: game properties, scripts, translations, input.
  ASCII/ANSI mode is still working, for backwards compatibility. This may be configured in the game project.
- Extended sprite compression options: lossless storage optimization for 16- and 32-bit sprites; LZW compression option for sprites in addition to existing RLE compression.
- GUI controls may now be told to clip their contents, which means that nothing gets drawn outside of their borders (as defined by X, Y, Width, Height properties). The only exception is Sliders, which are more complicated.
- The historical TTF fonts' "fixup" that altered their height and vertical offset is now optional and works only if backwards compatible option is set.
- Max number of AudioChannels is now 16 (was 8).
- Removed game Cursors hard limit (was 20).
- Increased Room Objects limit to 256 (was 40).
- Discontinued "Windows Game Explorer" support in both Editor and Engine.

Editor:
- Editor requires .NET Framework 4.6 to run.
- Added Android build target support (requires "Android component" installed).
- Added Web/Emscripten build target support (requires "Web build component" installed).
- Expanded UI color theme format, support global color options and allow missing entries.
- Script editor works in unicode mode.
- Added "Text format" option in General Settings which lets switching between ASCII/ANSI and Unicode (UTF-8) modes. This defines which format the game texts will be written in, when saving the game project and compiling the game.
- Added "Use old-style keyboard handling" option to the General Settings, which lets select between classic key press handling and new one meant for unicode chars support in scripts.
- Supports compiling UTF-8 translations. TRS file now has "Encoding" setting that tells how to interpret this TRS text.
- Added support for building multiple speech voxes, by taking files from the Speech subfolders.
- Added support for adding custom files into the game package. This is done by assigning a list of directories to "Package custom data folder" option in General Settings.
- Editor now copies a acsetup.cfg file from the project's root folder (if one is provided by) as a base for generating default config file. Settings from Default Setup will be written over, but other found options won't be removed.
- Added "Sprite file compression" option in General Settings, replacing "Compress the sprite file" option. The new option allows a selection of compression algorithm used for sprites.
  Currently supported: None, RLE (old default compression) and LZW.
- Added "Enable sprite storage optimization" option to the General Settings, that permits the editor to repack sprites in a different storage format, reducing their disk size whenever possible. This option may be used alongside with the sprite compression. Note that this does not change how the sprites work in game.
- Added "GUI controls clip their contents" option to the General Settings.
- Added "TTF fonts height used in the game logic" option to the General Settings, that makes your game use real font's pixel height when arranging text and text-based UI elements, as opposed to the nominal font's size.
- Added "Touch to Mouse Emulation", "Touch to Mouse motion mode" and "Display FPS on Screen" to Default Setup. Removed few deprecated options.
- Added "TTF font adjustment" property to Fonts, as well as to General Settings where it serves as a project default for the new fonts. This property lets you choose between "no changes" and backward compatible TTF fixup meant to keep fonts made for AGS displayed as they were meant to.
- In the "Import TTF" dialog added a choice to import the size closest to the given pixel height.
- Fonts now have Auto Outline Style and Auto Outline Thickness properties.
- Fonts now have a readonly Family Name field, that lets user see the original name of a font they've imported (if available).
- Added IdleDelay property to Characters that lets you set time needed to pass before IdleView is activated. This is equivalent to the Character.SetIdleView script function.
- Added Character.IdleAnimationDelay property to let setup idle view's animation speed.
- Added Cursor.AnimationDelay property to let setup cursor's animation speed.
- The TextWindow edges now have distinct names in the dropdown list of the property grid.
- Rooms created from a Blank template will now have default background of a game's resolution.
- When creating new room objects they will now have their script names set to some default value.
- Added Room.BackgroundAnimationEnabled property to let have disabled animation on room load.
- Editor will now create an empty sprite file if one is missing in the game project. Any existing sprite descriptions in the project will be kept, letting user to reimport these from sources.
- Added "File -> Restore all sprites from sources" menu command.
- Added "Apply" button on editor's Preferences dialog.
- In Preferences replaced "Import Color Theme" with a "Open Theme Folder", as a temporary solution for managing theme files.
- Select script editor's font in the editor's Preferences.
- Added "Help" option to the editor pane's tab context menu.
- Upgraded script editor to Scintilla 3.21.1 and ScintillaNET 3.6.3.
- Cursor's position in script is now displayed on the status bar.
- Dialog scripts now too can open help topics for keywords or script functions under cursor on F1.
- Added zoom controls for the Sprite Manager, Character, Cursor, Inventory and View panes.
- Sprites may now be imported by drag'n'drop into the Sprite manager.
- In sprite manager's context menu added command "Create source files for all sprites with missing / external sources..."
- In sprite manager's context menu added (restored) command "Replace sprite using previous files".
  Also made "previous file" remembered consistently whenever a sprite is imported or replaced.
- In sprite manager's "export all" dialog added "skip if inside project's folder" option.
- In sprite manager's "export all" dialog added "reset tile settings" option.
- On the View pane the frames having set delay and linked sound will be now indicated with icons.
- Editor no longer errors and fails when opening a game project with some script files missing.
- Editor no longer errors on empty translations when compiling the game.
- Editor now exports values of the string type Custom Properties to translations.
- Editor no longer prevents exporting string arguments from Get/SetTextProperty calls to TRS file.
- Editor now cleanups spritefile on game load, identifying any data not referenced by the project and marking it for deletion.
- Fixed editor silently enabling all available Build Targets when upgrading a pre-3.4.0 project. This could be very inconvenient as there are several of them supported now.
- Fixed open folders in the Project Tree were collapsing whenever you create a new subfolder or change an object's name in properties.
- Fixed editor was not preventing from entering Character's and AudioClip's ScriptName too long for the engine to handle.
- Fixed Image and View properties in various objects were allowing negative values.
- Fixed some of the object previews (at least GUI) could crash if user entered a non-existing sprite's number as an Image property.
- Fixed editor displaying unhandled exception if the script which user is trying to open was missing. Instead it will now open a blank script.
- Fixed room editor was suggesting to save the modified room even if no changes were made.
- Fixed a recently imported sprite could be displayed incorrectly scaled up in the room editor for high-resolution games, if the "Allow relative asset resolutions" was enabled in General Settings, and the sprite 0 had "Resolution" property set to "Low".
- Fixed program crash occuring on sprite's import if failed to open a source file for any reason.
- Fixed View animation preview stopping at frame 100 (if loop contains over 100 frames).
- Fixed going to a "find all" result in dialog script did not highlight the found text, and sometimes did not scroll down to it.
- Fixed "Goto Definition" not working for Enums and Defines (macros).
- Fixed script autocomplete sometimes was not updated right after opening a script.
- Fixed script autocomplete for function calls was mistreating commas in strings and inline comments as if they were separating actual parameters.
- Fixed script autocomplete was not displaying members of extended structs if the parent struct was declared in another header.
- Fixed script autocomplete was not working for enum names.
- Fixed structs and enums were not highlighted if declared inside a script's body.
- Fixed in dialogs numbers inside names were incorrectly highlighted as numeric values.
- Fixed matching or mismatching braces were not highlighted consistently at all times in regular and dialog scripts.
- Fixed crash occuring when user was trying to set breakpoint on the very last line in script.
- Fixed few editor panes were not opening correct help topics in F1.
- (Possibly) fixed error message text in the runtime error popup could be drawn partially beyond the popup borders if the user's system has text scaling option enabled.

Compiler:
- Support unicode character literals.
- Support using float literals when defining default values for function arguments.
- Support hexadecimal number literals (e.g. "0xABCDEF").
- Removed 500-characters line limit.

Script API:
- Expanded `on_key_press` callback, now supports two parameters: key code and key modifier flags.
- In the new key handling mode `on_key_press` is called for each actual key press;
  e.g. combinations like Ctrl+Z will result in two `on_key_press` calls, one with eKeyCtrlLeft and second with eKeyZ; added support for "NEW_KEYINPUT_API" macro in scripts.
- Implemented new `on_text_input(int ch)` callback which is called when the engine receives a printable character. This callback is essential for handling unicode chars in script.
- Similarily, expanded `dialog_options_key_press` with the third `mod` argument, and implemented `dialog_options_text_input` callback for receiving unicode chars during the custom dialog options state.
- Implemented `dialog_options_close` callback which is called when custom dialog options are removed from the screen. This allows to perform any required cleanup.
- Added eEventEnterRoomAfterFadein event for `on_event` callback, which corresponds to "enter after fade-in" room event.
- Added eKey constants for Shift, Control and Alt keys.
- Added eKeyMod enum for key modifiers constants.
- String.AppendChar(), ReplaceChar() functions and String.Chars[] property are now working with the unicode characters.
- String.Format("%c") specifier will now be able to print unicode characters.
- Extended Button.Animate() to have blocking style, direction and starting frame parameters, thus matching other Animate commands (of Character and Object).
- Extended all Animate() commands by adding "volume" parameter, that defines volume of the frame-linked sounds for the duration of this animation.
- Added Character.AnimationVolume, defining volume of the frame-linked sounds.
- Added Character.IdleAnimationDelay to let control idle view's animation speed.
- Character.Scaling is no longer limited by a range of 5-200 (now supports 1-32767).
- Hotspot.Name and Object.Name may now be set in script.
- Added Object.ManualScaling and Object.Scaling.
- Deprecated Object.IgnoreScaling (use Object.ManualScaling instead).
- Object.SetView default loop & frame values are now 0 (was -1 which retained loop and frame indexes from the previous view, often unexpected to the user).
- DrawingSurface.DrawImage() and DrawSurface() now support optional source rect coordinates.
- Added functions for getting DrawingSurface of room masks: GetDrawingSurfaceForWalkableArea(), GetDrawingSurfaceForWalkbehind(), Hotspot.GetDrawingSurface(), Region.GetDrawingSurface().
- Added new delay parameter to Mouse.ChangeModeView() to let control cursor's animation speed.
- Added Game.ChangeSpeechVox() and Game.SpeechVoxFilename, support switching the voice-over pack.
- Added Mouse.AutoLock property that toggles automatic mouse lock inside the game window.
- Added Room.Exists().
- Added System.Log().
- Added SkipWait() that skips any active Wait() function.
- Added WaitMouse() to complement existing Wait functions.
- Added InputType enum which defines input devices and lets create their sets as flags.
- Added WaitInput(), a more generic and extendable function that accepts a combination of flags telling which input types to wait for.
- All Wait* functions now may have infinite timeout if you pass a negative timeout parameter.
- All Wait* functions now return the reason they were skipped: a combination of InputType flag and a respective key or button code.
- Added GUIControl.Transparency property.
- Added Overlay.CreateRoomGraphical and CreateRoomTextual. Use these two functions to create "room overlays": that is - overlays that display a sprite inside the room, sorted among other room objects, characters and walk-behinds.
- Added readonly Overlay.InRoom property that tells if this is a room or screen overlay.
- Extended Overlay.CreateGraphical() with a new "clone" parameter that tells whether to assign a sprite index, or make a sprite's copy owned exclusively by this overlay. The former will save program memory but make overlay update if the sprite is edited later. The latter is meant primarily for backwards compatibility.
  Overlay.CreateRoomGraphical has the same param.
- Added Overlay.Graphic property that lets you change overlay's sprite after it's created.
- Added Overlay.Width and Height properties, that let you freely scale existing Overlay.
- Added readonly Overlay.GraphicWidth and GraphicHeight properties that let read original overlay's graphic size, as not all overlays hold a sprite reference (e.g. textual overlays).
- Added Overlay.Transparency property.
- Added Overlay.ZOrder property that lets you sort Overlays among themselves and other objects in the same "game layer": screen overlays are sorted among GUI, while room overlays are sorted among room objects, characters and walk-behinds.
- Added Speech.TextOverlay and Speech.PortraitOverlay for accessing blocking speech overlay and portrait overlay respectively.
- Added Game.BlockingWaitSkipped which tells the result of the last blocking wait skipping, also including result of the blocking speech skipping.
- SkipSpeechStyle now supports eSkipNone mode; when used it will disable any kind of skipping, such speech can be only skipped by a direct command from script.
- Extended Screen.ScreenToRoomPoint() with an optional "restrictToViewport" argument, which lets to choose whether tests over empty place result in conversion through the default viewport or a null pointer.
- Added AudioClip.PlayOnChannel().
- Added AudioChannel.Pause() and Resume() functions, and IsPaused property.
- Added AudioChannel.SeekMs(), complementing PositionMs (as the Seek() function interprets position differently depending on the audio format).
- PlayVideo() now supports an option to play both game's and video's audio track simultaneously.
- Added File.WriteRawInt() to complement ReadRawInt().
- File paths in script now support $DATA$ token, which tells to read files from the game package. This only works for read operations. Functions that support this token currently are:
  File.Open(), DynamicSprite.CreateFromFile(), ListBox.FillDirList().
- Debug(2, 0) command that displayed walkable areas is superceded by Debug(2, n), where "n" is a mask type: 0 - none, 1 - hotspots, 2 - walkbehinds, 3 - walkable areas, 4 - regions. This command also works as a toggle switch, calling it with the same mask index will turn it off.
- Debug(5, n) command that displayed character's walk paths now also works as a toggle switch.

Engine:
- New SDL2-based backend for graphics, audio and input.
- Hqx graphic filters discontinued (could be temporary).
- Windows-only DirectMedia video playback discontinued (could be temporary).
  Only OGG/OGV videos are kept supported at this point.
- Support resizing game window on desktop systems.
- Support "borderless full-screen window" mode in addition to the real (exclusive) fullscreen.
- Support for switching vertical sync at runtime with Direct3D/OpenGL renderers. Also enable vsync in windowed mode too.
- Unicode (UTF-8) text support: engine can now switch between ASCII and UTF-8 text mode. This is controlled by both game's OPT_GAMETEXTENCODING setting and translation's "Encoding" setting: they tells whether to interpret game texts as UTF-8 or ASCII/ANSI.
- Support optional translation's "GameEncoding" setting: it hints the original game's codepage to help with their conversion. This is mostly meant for translating existing older (ANSI) games.
- Engine now supports using real pixel height of the TTF fonts when arranging text and UI elements on screen; using nominal import size of the font is used as a compatible mode for the old games.
- Also supports separate "normal" and backward compatible "fixup" modes when initializing TTF fonts, letting to display both common TTFs and ones made specifically for AGS in the past to display as they were meant to be.
- Supports scripts using functions and variables from any other scripts, regardless of the script module order in the project.
- Removed limit of simultaneous Button animations.
- Removed limit of Character followers.
- Removed Overlay limit.
- Character.SetWalkSpeed() is no longer restricted by an arbitrary limit of 50.
- Process character's idle view based on real game speed, not hardcoded 40 fps.
- Improved file writing times (e.g. when doing a game save) by using buffered file stream. Initial tests showed 50% faster file writing.
- Engine now renders GUI controls as separate textures when using hardware accelerated renderers. This may significantly improve performance in the high-resolution games and games with large number of GUI elements on screen.
- Engine now shares the video texture data for all game objects on screen sharing same sprite. This improves performance in case there are multiple objects which use same image.
- Various performance optimizations for both raw drawing and texture updates (Direct3D/OpenGL).
- Engine now ensures that in threaded audio mode the AudioChannel's state only changes once the game is updated, and not while the game script is running. This prevents situations when the clip could begin playing before all properties are set in script, or when AudioChannel's properties' values (such as Position) could change while running a game script.
- 24-bit wav PCM support, comes with the new sound library.
- File.ReadRawLineBack() now always reads full line, and not limited to 200 characters anymore.
- Debug displays, such as showing room mask and character walk paths, are now implemented as non-blocking translucent overlays, allowing you to keep playing the game while they are on.
- Implemented debug key controls for calling a built-in save and restore game dialogs. These controls have to be set in user config as "save_game_key" and "restore_game_key" in "[override]" category. These may be used by testers if the game is missing a save function or one is bugged.
- Engine now supports loading compiled scripts as separate files packed along with the game, along with those embedded into the main game data or inside room files.
- Engine no longer bails out with error if the chosen translation cannot be loaded on startup.
- When reporting script errors, engine will print callstack for all the active script "threads": for example, if there's Wait() function called and error happened in repeatedly_execute_always, then it will print both actual error's location, and Wait() call's location.
- Engine config now has graphic modes defined as a simplier string options: "[graphics] fullscreen" for the fullscreen mode setup, and "[graphics] window" for the windowed.
  Fullscreen option can explicitly define a "borderless full-screen window" mode.
- Added "emul_mouse_mode" and "emul_mouse_relative" options to config in "[touch]" category.
- Added "cache_size" and "stream_threshold" options to config in "[sound]" category, they setup the rules for sound caching and choosing whether to load a clip fully into mem or stream one.
- Added "load_latest_save" and "show_fps" options to config in "[misc]" category.
- Added "background" option to config in "[misc]" category, that defines the starting run-in-background (aka multitasking) mode (may later be changed by SetMultitaskingMode()).
  Added "--background" command line option for the same purpose.
- Added "--sdl-log" command line option for setting up SDL2 library output verbosity. The engine log config now has a new "sdl" group meant for SDL2 messages.
- Support "--user-conf-dir" command-line arg (and "user_conf_dir" config option) superceding "--localuserconf"; the new option directly tells the location of user config file.
- Path related command-line and config options, - such as "shared_data_dir", "user_data_dir" and "user_conf_dir", now support $GAMENAME$ token in path which is resolved to the game's title.
- Added "--clear-cache-on-room-change" command-line arg (and similar config option).
- Don't error when DrawingSurface.DrawImage has bad transparency parameter (warning instead).
- Don't error when detecting bad format in File.Read* functions (warning instead).
- Added stubs for agsshell plugin (a contemporary cross-platform variant of ags_shell).
- Added stubs for agsappopenurl plugin.
- Fixed potential crashes if a room-related API function has been called in "game_start"; this is achieved by having a dummy room placeholder object. Still results of such calls are undefined and should not be relied upon.
- Fixed potential crash on room load if the walkable area mask contained color values above the supported range.
- Fixed dialog script's "goto-previous" command not working if used from the first sub-topic run using "goto-dialog" (a very-very old bug).
- Fixed AGS_EngineInitGfx plugin callback was not called during OpenGL renderer initialization.
- Fixed Direct3D/OpenGL renderers were displaying plugin's raw drawings in a wrong position in the scrolling rooms, if the drawing was done on AGSE_PRESCREENDRAW or AGSE_POSTROOMDRAW events.
- Fixed overlay may fail to be created sometimes, if previously another overlay had been forcefully removed when changing rooms (this is an ancient bug which existed for many years).
- Fixed ListBox.RowCount reporting 0 if called before the control was displayed once.
- Fixed GetTextWidth would still return a size of an outline for an empty text string.
- Fixed text may be misaligned in gui controls, as its outline thickness is not counted.
- Fixed some TTF fonts could be cut at the bottom when the speech is displayed.
- Fixed scheduled sound fadeout effect was not cancelled by skipping a cutscene.
- Fixed OGV Theora videos positioned incorrectly if they have certain sizes or aspect ratios.
- Fixed game fps sped up if SetGameSpeed() is called repeatedly in game script.
- Fixed game not reacting to system close commands when stuck in script, which made it impossible
  to close the "hanging" game by usual means (other than terminating the process).

Engine Plugin API:
- Added IAGSEngine::GetGameInfo() function which returns information about the game, such as its title and GUID.
- Added new render callback AGSE_POSTROOMDRAW, for handling drawing inside the room above all room objects.
- Added IAGSFontRenderer2 interface, expanding the original font renderer interface, improving font plugins support.
- Added ReplaceFontRenderer2() and NotifyFontUpdated() functions.

Compatibility:
- Fallback to the first loop with frames if current character's loop does not have any.
- Use the dummy frame if current character's speech view loop does not have any.
- Ignore character having view/loop with no frames while it's not in the current room.
- Legacy behavior of MoveCharacterBlocking's return value.
- Fixed walkable area's continuous scaling was broken for high-res rooms in old games.
- In pre-3.* games force player to walkable area after changing rooms, this is to emulate an unintentional effect created by the old engines.
- Fixed pre-3.4.1 anti-aliased TTF fonts display (their vertical position was broken).
- For pre-3.5.0 games support old behavior of coincidental dynamic sprite replacement on GUI backgrounds (and few other places) without explicit assignment; that is - when the new DynamicSprite is created right after deleting an old one.
- Support Label.TextAlignment with legacy alignment constants for pre-3.5.0 games made with the custom engine from "Clifftop Games".
- Support native resolution hack for games made with "Clifftop Games" custom engine, where 640x400 games are run as 640x360.

Android:
- Rewrote universal AGS game launcher/player using up-to-date Google guidelines. The former "launcher" is now called "AGS Player".
- Implemented single game project template meant for building your own signed APK.
- Implemented two touch-to-mouse control scheme (selectable in config), for one finger emulating LMB only, and for two fingers emulating LMB and RMB.
- Support relative motion speed setting for touch-to-mouse emulation.
- In AGS Player added "Browse" button to the game folder selection, which opens default system file picker.
- AGS Player now searches for games recursively, in all the subfolders.
- AGS Player now has preference button per each game, which opens individual game's settings.

OSX:
- OpenGL renderer is now supported on MacOS.

Web / Emscripten:
- Initial port release.

Windows:
- Installer will create program links with three-digit version in the name.

Plugins:
- Added SpriteFont plugin to the list of builtins, for ports that use ones.
  SpriteFont plugin is updated to support custom "Clifftop Games" font variants.

WinSetup:
- Added "Fullscreen as borderless window" checkbox.
- Remade sound options to reflect the move to the new audio system in the engine.




Known issues

* Although Unicode text is supported overall, some languages may still not be printed correctly automatically. Firstly, those that require "letter linking", such as Arabic or Persian, do not have the proper linking on its own. This may be worked around using special text converters and fonts. Another issue is that texts printed right-to-left in the source (where print direction is done using Unicode's control characters) are not wrapped correctly and may require manual placement of line breaks, or scripting their split in game.
* MIDI no longer plays on its own on Windows. For MIDI you (and your players) must install "sound banks" (also known as "sound font"). Please refer to this article: https://adventuregamestudio.github.io/ags-manual/MIDI-playback.html
* AudioChannel.Position and AudioChannel.Seek do not work for MIDI and MOD sounds. Try sticking to PositionMs and SeekMs for now.
* There are reports about Direct3D not being able to restore the fullscreen mode after alt+tabbing occasionaly.





Thanks to everyone who contributed to and tested this version!

I'm posting in this general tech section to be able to gather more opinions (maybe people look here more often than in "engine development"?)

I will have to explain something first, so please bear with me.

AGS historically has a hidden problem: its pathfinder and walking algorithm uses math with relatively low precision. This may result in rounding mistakes. What this means in practice is that under some circumstances the "movement direction" (vector) is slightly off, e.g. more towards X than Y (or other way). In such case the character may reach the X destination while Y destination is still few pixels away. This difference mostly depends on the walk length. By experiment, I think, in 320x200 area it rarely exceeds 2-3 pixels, but in larger areas (walking fully across a scrolling rooms, or walking around high-res rooms) it may actually be bigger, like 5+ pixels.

In AGS 4 Alan Drake had changed the math to use proper floating-point math, which seems to improve this situation (but I did not experiment much with that yet).

In the AGS 3.* branch I am afraid to make such change, because of the backwards compatibility with games, which may be scripted to depend on how character walks exactly (that is unfortunate, but ags 3 is still used to run these old games, as well as its scummvm port).

How is this issue solved currently in AGS (and for a long time):
When AGS finds out that one coordinate is complete, but another is not (for example X done and Y is still not reached), it starts waiting until character reaches Y, but also accepts a certain "mistake", in 2-3 pixels.
If character is already within 2-3 pixels from the destination, then it just stops. This makes its real stopping point inaccurate, but nothing else happens.
However, if character is further away, then it keeps "walking", but because the movement vector is still pointing in the same direction, usually it takes few moments for it to reach the proper Y coordinate.
This results in a buggy effect known as "walking in place".
Here's the actual example:

In the end, not only the character may end up in a slightly wrong position (2-3 pixels away), but there's a chance this above animating in place happening, which looks quite weird.

I guess that there may be various approaches to solve this problem. Currently I'm experimenting with a solution where engine will, so to speak, turn the walking vector to make it point right along the unfinished axis, while keeping its length (that means - walking speed), in order to reach the destination faster. At the same time, I removed the "mistake acceptance" completely, forcing character to always reach the requested destination.
This should make character make some extra short move, properly animating, but this may look more natural than just moving legs in place.

Now, the reason why I explain all this here, is that a result of this solution is that the character may make a kind of a "final step" in a slightly different direction in the end. And I've been wondering how acceptable or non-acceptable this looks like.

Here's a compiled game i used for the test:
https://www.dropbox.com/scl/fi/r52c6zy1odiabeuwnautu/walk-problem-test.zip?rlkey=3e9yfgeze8dujeeb1n4ov6d3u&dl=0
I scripted this game to make a walk between very particular coordinates that illustrate this problem case: this is done by pressing Space button.
But in theory it may be possible to have similar effect when walking around the room for the long distances.

Of course I may be overthinking this too...

Summary

AGS 3.6.0 is another big change to AGS.
First of all, this release presents a SDL2-based engine. For about 2 decades AGS engine was based on Allegro 4 graphic library, which was discontinued somewhere in the early 2010-ies (only received few patches since). There was an intent to move to to Allegro 5 or SDL since, but for various reasons this task was continuously postponed. Now it's done.
Secondly the Editor and Engine now have full Unicode support. This means that you may use any language whatsoever in scripts, object descriptions and custom properties, as well as translations; so long as you also provide proper unicode fonts.
Third, we have finally expanded a list of platforms that the Editor can build for: now this includes Android and Web (Emscripten) port.

There are much more changes and improvements in this release, check out the full list of changes below.
Also, please be sure to read "Upgrading to AGS 3.6" topic in the manual: https://adventuregamestudio.github.io/ags-manual/UpgradeTo36.html



Changes in the Patch 5:

Editor:
 - Reimplemented multiple sprites properties editing in the Sprite Manager. This ability was dropped in 3.5.0 unintentionally.
 - Fixed Autocomplete not treating certain struct members as "static" or "protected" if their declaration is too long.

Engine:
 - Fixed Character.WalkStraight() was resetting walking animation if called during walking.
 - Fixed Character's idle animation getting reset to frame 0 when the speech is played without a valid speech view (idle animation should continue playing in such case).
 - Fixed idle animation sometimes not starting immediately after Character finishes walking.
 - Fixed a crash occuring if script tries to get or set a custom property for a non-existing Room Object (this seem possible to do by iterating over `object[]` array).

Compatibility:
 - Implemented "legacysave_assume_dataver" override option in config, which lets to instruct the engine which game data version to assume when restoring legacy (pre-3.5.0) saves. This "hack" appeared to be necessary because of a mistake done during development of the older engine versions, where the save format was changed, but engine was made to rely on the game data version instead of incrementing save format index.
 - Implemented "legacysave_let_gui_diff" override option in config, which lets the engine to read less gui elements from restored save than the number registered by the game. This is to emulate a (possibly unintended) effect in pre-3.5.0 saves.
 - Fixed engine could try to load game data from game.exe without checking whether data is actually appended to it when restoring a legacy save in a game with a different file structure.
 - Fixed number of GUI elements were not tested when loading a legacy save, which could lead to GUI data getting overwritten incorrectly without a warning if number of controls changed since. If the test failed, engine will act according to "legacysave_let_gui_diff" config option: either quit with error or log a warning and continue.

Plugins:
 - Fixed potential "index out of bounds" exceptions in the built-in PalRender plugin.

Templates:
 - In "Verb Coin" template fixed action label could be updated incorrectly if the cursor was moved over buttons on any other GUI.


Changes in the Patch 4:

Editor:
 - Export Game's Title into translations.
 - Fixed Game.agf was not created after importing a 2.* game project (regression in 3.6.0).

Engine:
 - Character.AnimationVolume property is now applied to the portrait animation as well.
 - Removed few of the less important game messages from logging, because they may quickly clutter the log under some circumstances.
 - Fixed when animating a character portrait, the first frame's linked sound is not played.
 - Fixed IsSpeechVoxAvailable() returning positive result if run from IDE and Speech folder is empty.
 - Fixed speech and messages were skipped by modifiers and other special keys (Ctrl, Alt, etc).
 - Fixed crash occuring when you resize DynamicSprite while it is displayed on screen.
 - Fixed audio clip started right before a ChangeRoom would not play until after the room changes.
 - Fixed in Software display mode the room Overlays may not be properly covered by a walk-behind under very specific conditions.
 - Fixed System.Log() would cause engine crash if there are more format placeholders than args.
 - Fixed some game options that are not allowed to be changed at runtime could still be overwritten when restoring an old save, leading to a weird game behavior.


Changes in the Patch 3:

Editor:
 - Don't error when loading a room file which has unsupported number of events, instead these will be cut out. This may let e.g. use room templates from newer versions of AGS.
 - Sprite's default property is changed from deprecated Resolution setting to SourceFile.
 - Fixed full spritefile recreation would write duplicate sprites into the spritefile, if game project (Game.agf file) contained multiple sprites with same ID for any reason (for example, if they were added by manually editing Game.agf).
 - Fixed importing SCI fonts with >128 chars.
 - Fixed font preview did not properly display characters with indexes 128-255.

Engine:
 - Fixed "noloopcheck" script function modifier was not handled correctly sometimes.
 - Fixed a button with inventory placeholder did not update immediately when the active inventory is set.
 - Fixed textual GUIs were not redrawn immediately after a call to SetGameOption(OPT_RIGHTTOLEFT).


Changes in the Patch 2:

Common:
- Fixed a TTF font could cause a crash in the Editor or the Engine if the font renderer tries to draw a letter with higher number than the highest glyph number in the font.

Editor:
- Added "Restore all sprites..." command to the Sprite Manager's context menu (this duplicates the "File -> Recreate sprite file" menu command added previously).
- Refresh Sprite Manager after fully recreating a sprite file.
- Sprites will now hide their "Resolution" property if the game settings have "Allow relative asset resolutions" disabled. This is to avoid user's misuse of this property.
- Fixed a minor memory leak occuring when editing a tree item's label in Project Explorer.

Engine:
- Engine will now find and load plugins in the game dir when run from a different location.
- Fixed crash occuring if Character was told to FaceLocation while "Turn to face" game setting is enabled, and character's View does not have enough loops.
- Fixed Character resetting current non-blocking animation if it was ordered to Move, as soon as it arrives at destination.
- Fixed crash occuring if a GUI button was somehow set a negative NormalImage number.
- Fixed "bad script stack" error could be sometimes displayed if the game was aborted in the middle of running a script.


Changes in the Patch 1:

Editor:
- Fixed room's deprecated setting LegacyMusicVolumeAdjustment not applied correctly.

Engine:
- Fixed Room Objects whose dynamic sprite was deleted in "leave room" event becoming invisible during fade-out transition. Logically this has to happen, but historically they kept displaying until the transition end, so we restored this behavior for compatibility, and simply because there's no "after fade-out" event in the engine yet to delete these sprites.
- Fixed Game.StopAudio() fails to remove queued clips if no particular audio type id is requested.
- Fixed performance regression in the script related to long loops (regression in 3.6.0).
- Fixed memory leak occuring when printing text in Right-to-left mode (regression in 3.6.0).
- Fixed rare mistake during text wrapping which may occur if a Unicode text is cut in the middle of the word.
- Fixed playing certain WAVs caused game to freeze forever on exit.

Compatibility:
- Fixed frame-linked sounds not playing in the games made before 3.6.0.
- Allow game to call DynamicSprite.Create() with negative size, clamping it to 1x1.

Templates:
- In Sierra-style template fixed "mouse over" graphic for the "Load" icon.



What is new in 3.6.0

Common features:
- Full Unicode support for all game texts: game properties, scripts, translations, input.
  ASCII/ANSI mode is still working, for backwards compatibility. This may be configured in the game project.
- Extended sprite compression options: lossless storage optimization for 16- and 32-bit sprites; LZW compression option for sprites in addition to existing RLE compression.
- GUI controls may now be told to clip their contents, which means that nothing gets drawn outside of their borders (as defined by X, Y, Width, Height properties). The only exception is Sliders, which are more complicated.
- The historical TTF fonts' "fixup" that altered their height and vertical offset is now optional and works only if backwards compatible option is set.
- Max number of AudioChannels is now 16 (was 8).
- Removed game Cursors hard limit (was 20).
- Increased Room Objects limit to 256 (was 40).
- Discontinued "Windows Game Explorer" support in both Editor and Engine.

Editor:
- Editor requires .NET Framework 4.6 to run.
- Added Android build target support (requires "Android component" installed).
- Added Web/Emscripten build target support (requires "Web build component" installed).
- Expanded UI color theme format, support global color options and allow missing entries.
- Script editor works in unicode mode.
- Added "Text format" option in General Settings which lets switching between ASCII/ANSI and Unicode (UTF-8) modes. This defines which format the game texts will be written in, when saving the game project and compiling the game.
- Added "Use old-style keyboard handling" option to the General Settings, which lets select between classic key press handling and new one meant for unicode chars support in scripts.
- Supports compiling UTF-8 translations. TRS file now has "Encoding" setting that tells how to interpret this TRS text.
- Added support for building multiple speech voxes, by taking files from the Speech subfolders.
- Added support for adding custom files into the game package. This is done by assigning a list of directories to "Package custom data folder" option in General Settings.
- Editor now copies a acsetup.cfg file from the project's root folder (if one is provided by) as a base for generating default config file. Settings from Default Setup will be written over, but other found options won't be removed.
- Added "Sprite file compression" option in General Settings, replacing "Compress the sprite file" option. The new option allows a selection of compression algorithm used for sprites.
  Currently supported: None, RLE (old default compression) and LZW.
- Added "Enable sprite storage optimization" option to the General Settings, that permits the editor to repack sprites in a different storage format, reducing their disk size whenever possible. This option may be used alongside with the sprite compression. Note that this does not change how the sprites work in game.
- Added "GUI controls clip their contents" option to the General Settings.
- Added "TTF fonts height used in the game logic" option to the General Settings, that makes your game use real font's pixel height when arranging text and text-based UI elements, as opposed to the nominal font's size.
- Added "Touch to Mouse Emulation", "Touch to Mouse motion mode" and "Display FPS on Screen" to Default Setup. Removed few deprecated options.
- Added "TTF font adjustment" property to Fonts, as well as to General Settings where it serves as a project default for the new fonts. This property lets you choose between "no changes" and backward compatible TTF fixup meant to keep fonts made for AGS displayed as they were meant to.
- In the "Import TTF" dialog added a choice to import the size closest to the given pixel height.
- Fonts now have Auto Outline Style and Auto Outline Thickness properties.
- Fonts now have a readonly Family Name field, that lets user see the original name of a font they've imported (if available).
- Added IdleDelay property to Characters that lets you set time needed to pass before IdleView is activated. This is equivalent to the Character.SetIdleView script function.
- Added Character.IdleAnimationDelay property to let setup idle view's animation speed.
- Added Cursor.AnimationDelay property to let setup cursor's animation speed.
- The TextWindow edges now have distinct names in the dropdown list of the property grid.
- Rooms created from a Blank template will now have default background of a game's resolution.
- When creating new room objects they will now have their script names set to some default value.
- Added Room.BackgroundAnimationEnabled property to let have disabled animation on room load.
- Editor will now create an empty sprite file if one is missing in the game project. Any existing sprite descriptions in the project will be kept, letting user to reimport these from sources.
- Added "File -> Restore all sprites from sources" menu command.
- Added "Apply" button on editor's Preferences dialog.
- In Preferences replaced "Import Color Theme" with a "Open Theme Folder", as a temporary solution for managing theme files.
- Select script editor's font in the editor's Preferences.
- Added "Help" option to the editor pane's tab context menu.
- Upgraded script editor to Scintilla 3.21.1 and ScintillaNET 3.6.3.
- Cursor's position in script is now displayed on the status bar.
- Dialog scripts now too can open help topics for keywords or script functions under cursor on F1.
- Added zoom controls for the Sprite Manager, Character, Cursor, Inventory and View panes.
- Sprites may now be imported by drag'n'drop into the Sprite manager.
- In sprite manager's context menu added command "Create source files for all sprites with missing / external sources..."
- In sprite manager's context menu added (restored) command "Replace sprite using previous files".
  Also made "previous file" remembered consistently whenever a sprite is imported or replaced.
- In sprite manager's "export all" dialog added "skip if inside project's folder" option.
- In sprite manager's "export all" dialog added "reset tile settings" option.
- On the View pane the frames having set delay and linked sound will be now indicated with icons.
- Editor no longer errors and fails when opening a game project with some script files missing.
- Editor no longer errors on empty translations when compiling the game.
- Editor now exports values of the string type Custom Properties to translations.
- Editor no longer prevents exporting string arguments from Get/SetTextProperty calls to TRS file.
- Editor now cleanups spritefile on game load, identifying any data not referenced by the project and marking it for deletion.
- Fixed editor silently enabling all available Build Targets when upgrading a pre-3.4.0 project. This could be very inconvenient as there are several of them supported now.
- Fixed open folders in the Project Tree were collapsing whenever you create a new subfolder or change an object's name in properties.
- Fixed editor was not preventing from entering Character's and AudioClip's ScriptName too long for the engine to handle.
- Fixed Image and View properties in various objects were allowing negative values.
- Fixed some of the object previews (at least GUI) could crash if user entered a non-existing sprite's number as an Image property.
- Fixed editor displaying unhandled exception if the script which user is trying to open was missing. Instead it will now open a blank script.
- Fixed room editor was suggesting to save the modified room even if no changes were made.
- Fixed a recently imported sprite could be displayed incorrectly scaled up in the room editor for high-resolution games, if the "Allow relative asset resolutions" was enabled in General Settings, and the sprite 0 had "Resolution" property set to "Low".
- Fixed program crash occuring on sprite's import if failed to open a source file for any reason.
- Fixed View animation preview stopping at frame 100 (if loop contains over 100 frames).
- Fixed going to a "find all" result in dialog script did not highlight the found text, and sometimes did not scroll down to it.
- Fixed "Goto Definition" not working for Enums and Defines (macros).
- Fixed script autocomplete sometimes was not updated right after opening a script.
- Fixed script autocomplete for function calls was mistreating commas in strings and inline comments as if they were separating actual parameters.
- Fixed script autocomplete was not displaying members of extended structs if the parent struct was declared in another header.
- Fixed script autocomplete was not working for enum names.
- Fixed structs and enums were not highlighted if declared inside a script's body.
- Fixed in dialogs numbers inside names were incorrectly highlighted as numeric values.
- Fixed matching or mismatching braces were not highlighted consistently at all times in regular and dialog scripts.
- Fixed crash occuring when user was trying to set breakpoint on the very last line in script.
- Fixed few editor panes were not opening correct help topics in F1.
- (Possibly) fixed error message text in the runtime error popup could be drawn partially beyond the popup borders if the user's system has text scaling option enabled.

Compiler:
- Support unicode character literals.
- Support using float literals when defining default values for function arguments.
- Support hexadecimal number literals (e.g. "0xABCDEF").
- Removed 500-characters line limit.

Script API:
- Expanded `on_key_press` callback, now supports two parameters: key code and key modifier flags.
- In the new key handling mode `on_key_press` is called for each actual key press;
  e.g. combinations like Ctrl+Z will result in two `on_key_press` calls, one with eKeyCtrlLeft and second with eKeyZ; added support for "NEW_KEYINPUT_API" macro in scripts.
- Implemented new `on_text_input(int ch)` callback which is called when the engine receives a printable character. This callback is essential for handling unicode chars in script.
- Similarily, expanded `dialog_options_key_press` with the third `mod` argument, and implemented `dialog_options_text_input` callback for receiving unicode chars during the custom dialog options state.
- Implemented `dialog_options_close` callback which is called when custom dialog options are removed from the screen. This allows to perform any required cleanup.
- Added eEventEnterRoomAfterFadein event for `on_event` callback, which corresponds to "enter after fade-in" room event.
- Added eKey constants for Shift, Control and Alt keys.
- Added eKeyMod enum for key modifiers constants.
- String.AppendChar(), ReplaceChar() functions and String.Chars[] property are now working with the unicode characters.
- String.Format("%c") specifier will now be able to print unicode characters.
- Extended Button.Animate() to have blocking style, direction and starting frame parameters, thus matching other Animate commands (of Character and Object).
- Extended all Animate() commands by adding "volume" parameter, that defines volume of the frame-linked sounds for the duration of this animation.
- Added Character.AnimationVolume, defining volume of the frame-linked sounds.
- Added Character.IdleAnimationDelay to let control idle view's animation speed.
- Character.Scaling is no longer limited by a range of 5-200 (now supports 1-32767).
- Hotspot.Name and Object.Name may now be set in script.
- Added Object.ManualScaling and Object.Scaling.
- Deprecated Object.IgnoreScaling (use Object.ManualScaling instead).
- Object.SetView default loop & frame values are now 0 (was -1 which retained loop and frame indexes from the previous view, often unexpected to the user).
- DrawingSurface.DrawImage() and DrawSurface() now support optional source rect coordinates.
- Added functions for getting DrawingSurface of room masks: GetDrawingSurfaceForWalkableArea(), GetDrawingSurfaceForWalkbehind(), Hotspot.GetDrawingSurface(), Region.GetDrawingSurface().
- Added new delay parameter to Mouse.ChangeModeView() to let control cursor's animation speed.
- Added Game.ChangeSpeechVox() and Game.SpeechVoxFilename, support switching the voice-over pack.
- Added Mouse.AutoLock property that toggles automatic mouse lock inside the game window.
- Added Room.Exists().
- Added System.Log().
- Added SkipWait() that skips any active Wait() function.
- Added WaitMouse() to complement existing Wait functions.
- Added InputType enum which defines input devices and lets create their sets as flags.
- Added WaitInput(), a more generic and extendable function that accepts a combination of flags telling which input types to wait for.
- All Wait* functions now may have infinite timeout if you pass a negative timeout parameter.
- All Wait* functions now return the reason they were skipped: a combination of InputType flag and a respective key or button code.
- Added GUIControl.Transparency property.
- Added Overlay.CreateRoomGraphical and CreateRoomTextual. Use these two functions to create "room overlays": that is - overlays that display a sprite inside the room, sorted among other room objects, characters and walk-behinds.
- Added readonly Overlay.InRoom property that tells if this is a room or screen overlay.
- Extended Overlay.CreateGraphical() with a new "clone" parameter that tells whether to assign a sprite index, or make a sprite's copy owned exclusively by this overlay. The former will save program memory but make overlay update if the sprite is edited later. The latter is meant primarily for backwards compatibility.
  Overlay.CreateRoomGraphical has the same param.
- Added Overlay.Graphic property that lets you change overlay's sprite after it's created.
- Added Overlay.Width and Height properties, that let you freely scale existing Overlay.
- Added readonly Overlay.GraphicWidth and GraphicHeight properties that let read original overlay's graphic size, as not all overlays hold a sprite reference (e.g. textual overlays).
- Added Overlay.Transparency property.
- Added Overlay.ZOrder property that lets you sort Overlays among themselves and other objects in the same "game layer": screen overlays are sorted among GUI, while room overlays are sorted among room objects, characters and walk-behinds.
- Added Speech.TextOverlay and Speech.PortraitOverlay for accessing blocking speech overlay and portrait overlay respectively.
- Added Game.BlockingWaitSkipped which tells the result of the last blocking wait skipping, also including result of the blocking speech skipping.
- SkipSpeechStyle now supports eSkipNone mode; when used it will disable any kind of skipping, such speech can be only skipped by a direct command from script.
- Extended Screen.ScreenToRoomPoint() with an optional "restrictToViewport" argument, which lets to choose whether tests over empty place result in conversion through the default viewport or a null pointer.
- Added AudioClip.PlayOnChannel().
- Added AudioChannel.Pause() and Resume() functions, and IsPaused property.
- Added AudioChannel.SeekMs(), complementing PositionMs (as the Seek() function interprets position differently depending on the audio format).
- PlayVideo() now supports an option to play both game's and video's audio track simultaneously.
- Added File.WriteRawInt() to complement ReadRawInt().
- File paths in script now support $DATA$ token, which tells to read files from the game package. This only works for read operations. Functions that support this token currently are:
  File.Open(), DynamicSprite.CreateFromFile(), ListBox.FillDirList().
- Debug(2, 0) command that displayed walkable areas is superceded by Debug(2, n), where "n" is a mask type: 0 - none, 1 - hotspots, 2 - walkbehinds, 3 - walkable areas, 4 - regions. This command also works as a toggle switch, calling it with the same mask index will turn it off.
- Debug(5, n) command that displayed character's walk paths now also works as a toggle switch.

Engine:
- New SDL2-based backend for graphics, audio and input.
- Hqx graphic filters discontinued (could be temporary).
- Windows-only DirectMedia video playback discontinued (could be temporary).
  Only OGG/OGV videos are kept supported at this point.
- Support resizing game window on desktop systems.
- Support "borderless full-screen window" mode in addition to the real (exclusive) fullscreen.
- Support for switching vertical sync at runtime with Direct3D/OpenGL renderers. Also enable vsync in windowed mode too.
- Unicode (UTF-8) text support: engine can now switch between ASCII and UTF-8 text mode. This is controlled by both game's OPT_GAMETEXTENCODING setting and translation's "Encoding" setting: they tells whether to interpret game texts as UTF-8 or ASCII/ANSI.
- Support optional translation's "GameEncoding" setting: it hints the original game's codepage to help with their conversion. This is mostly meant for translating existing older (ANSI) games.
- Engine now supports using real pixel height of the TTF fonts when arranging text and UI elements on screen; using nominal import size of the font is used as a compatible mode for the old games.
- Also supports separate "normal" and backward compatible "fixup" modes when initializing TTF fonts, letting to display both common TTFs and ones made specifically for AGS in the past to display as they were meant to be.
- Supports scripts using functions and variables from any other scripts, regardless of the script module order in the project.
- Removed limit of simultaneous Button animations.
- Removed limit of Character followers.
- Removed Overlay limit.
- Character.SetWalkSpeed() is no longer restricted by an arbitrary limit of 50.
- Process character's idle view based on real game speed, not hardcoded 40 fps.
- Improved file writing times (e.g. when doing a game save) by using buffered file stream. Initial tests showed 50% faster file writing.
- Engine now renders GUI controls as separate textures when using hardware accelerated renderers. This may significantly improve performance in the high-resolution games and games with large number of GUI elements on screen.
- Engine now shares the video texture data for all game objects on screen sharing same sprite. This improves performance in case there are multiple objects which use same image.
- Various performance optimizations for both raw drawing and texture updates (Direct3D/OpenGL).
- Engine now ensures that in threaded audio mode the AudioChannel's state only changes once the game is updated, and not while the game script is running. This prevents situations when the clip could begin playing before all properties are set in script, or when AudioChannel's properties' values (such as Position) could change while running a game script.
- 24-bit wav PCM support, comes with the new sound library.
- File.ReadRawLineBack() now always reads full line, and not limited to 200 characters anymore.
- Debug displays, such as showing room mask and character walk paths, are now implemented as non-blocking translucent overlays, allowing you to keep playing the game while they are on.
- Implemented debug key controls for calling a built-in save and restore game dialogs. These controls have to be set in user config as "save_game_key" and "restore_game_key" in "[override]" category. These may be used by testers if the game is missing a save function or one is bugged.
- Engine now supports loading compiled scripts as separate files packed along with the game, along with those embedded into the main game data or inside room files.
- Engine no longer bails out with error if the chosen translation cannot be loaded on startup.
- When reporting script errors, engine will print callstack for all the active script "threads": for example, if there's Wait() function called and error happened in repeatedly_execute_always, then it will print both actual error's location, and Wait() call's location.
- Engine config now has graphic modes defined as a simplier string options: "[graphics] fullscreen" for the fullscreen mode setup, and "[graphics] window" for the windowed.
  Fullscreen option can explicitly define a "borderless full-screen window" mode.
- Added "emul_mouse_mode" and "emul_mouse_relative" options to config in "[touch]" category.
- Added "cache_size" and "stream_threshold" options to config in "[sound]" category, they setup the rules for sound caching and choosing whether to load a clip fully into mem or stream one.
- Added "load_latest_save" and "show_fps" options to config in "[misc]" category.
- Added "background" option to config in "[misc]" category, that defines the starting run-in-background (aka multitasking) mode (may later be changed by SetMultitaskingMode()).
  Added "--background" command line option for the same purpose.
- Added "--sdl-log" command line option for setting up SDL2 library output verbosity. The engine log config now has a new "sdl" group meant for SDL2 messages.
- Support "--user-conf-dir" command-line arg (and "user_conf_dir" config option) superceding "--localuserconf"; the new option directly tells the location of user config file.
- Path related command-line and config options, - such as "shared_data_dir", "user_data_dir" and "user_conf_dir", now support $GAMENAME$ token in path which is resolved to the game's title.
- Added "--clear-cache-on-room-change" command-line arg (and similar config option).
- Don't error when DrawingSurface.DrawImage has bad transparency parameter (warning instead).
- Don't error when detecting bad format in File.Read* functions (warning instead).
- Added stubs for agsshell plugin (a contemporary cross-platform variant of ags_shell).
- Added stubs for agsappopenurl plugin.
- Fixed potential crashes if a room-related API function has been called in "game_start"; this is achieved by having a dummy room placeholder object. Still results of such calls are undefined and should not be relied upon.
- Fixed potential crash on room load if the walkable area mask contained color values above the supported range.
- Fixed dialog script's "goto-previous" command not working if used from the first sub-topic run using "goto-dialog" (a very-very old bug).
- Fixed AGS_EngineInitGfx plugin callback was not called during OpenGL renderer initialization.
- Fixed Direct3D/OpenGL renderers were displaying plugin's raw drawings in a wrong position in the scrolling rooms, if the drawing was done on AGSE_PRESCREENDRAW or AGSE_POSTROOMDRAW events.
- Fixed overlay may fail to be created sometimes, if previously another overlay had been forcefully removed when changing rooms (this is an ancient bug which existed for many years).
- Fixed ListBox.RowCount reporting 0 if called before the control was displayed once.
- Fixed GetTextWidth would still return a size of an outline for an empty text string.
- Fixed text may be misaligned in gui controls, as its outline thickness is not counted.
- Fixed some TTF fonts could be cut at the bottom when the speech is displayed.
- Fixed scheduled sound fadeout effect was not cancelled by skipping a cutscene.
- Fixed OGV Theora videos positioned incorrectly if they have certain sizes or aspect ratios.
- Fixed game fps sped up if SetGameSpeed() is called repeatedly in game script.
- Fixed game not reacting to system close commands when stuck in script, which made it impossible
  to close the "hanging" game by usual means (other than terminating the process).

Engine Plugin API:
- Added IAGSEngine::GetGameInfo() function which returns information about the game, such as its title and GUID.
- Added new render callback AGSE_POSTROOMDRAW, for handling drawing inside the room above all room objects.
- Added IAGSFontRenderer2 interface, expanding the original font renderer interface, improving font plugins support.
- Added ReplaceFontRenderer2() and NotifyFontUpdated() functions.

Compatibility:
- Fallback to the first loop with frames if current character's loop does not have any.
- Use the dummy frame if current character's speech view loop does not have any.
- Ignore character having view/loop with no frames while it's not in the current room.
- Legacy behavior of MoveCharacterBlocking's return value.
- Fixed walkable area's continuous scaling was broken for high-res rooms in old games.
- In pre-3.* games force player to walkable area after changing rooms, this is to emulate an unintentional effect created by the old engines.
- Fixed pre-3.4.1 anti-aliased TTF fonts display (their vertical position was broken).
- For pre-3.5.0 games support old behavior of coincidental dynamic sprite replacement on GUI backgrounds (and few other places) without explicit assignment; that is - when the new DynamicSprite is created right after deleting an old one.
- Support Label.TextAlignment with legacy alignment constants for pre-3.5.0 games made with the custom engine from "Clifftop Games".
- Support native resolution hack for games made with "Clifftop Games" custom engine, where 640x400 games are run as 640x360.

Android:
- Rewrote universal AGS game launcher/player using up-to-date Google guidelines. The former "launcher" is now called "AGS Player".
- Implemented single game project template meant for building your own signed APK.
- Implemented two touch-to-mouse control scheme (selectable in config), for one finger emulating LMB only, and for two fingers emulating LMB and RMB.
- Support relative motion speed setting for touch-to-mouse emulation.
- In AGS Player added "Browse" button to the game folder selection, which opens default system file picker.
- AGS Player now searches for games recursively, in all the subfolders.
- AGS Player now has preference button per each game, which opens individual game's settings.

OSX:
- OpenGL renderer is now supported on MacOS.

Web / Emscripten:
- Initial port release.

Windows:
- Installer will create program links with three-digit version in the name.

Plugins:
- Added SpriteFont plugin to the list of builtins, for ports that use ones.
  SpriteFont plugin is updated to support custom "Clifftop Games" font variants.

WinSetup:
- Added "Fullscreen as borderless window" checkbox.
- Remade sound options to reflect the move to the new audio system in the engine.




Known issues

* Although Unicode text is supported overall, some languages may still not be printed correctly automatically. Firstly, those that require "letter linking", such as Arabic or Persian, do not have the proper linking on its own. This may be worked around using special text converters and fonts. Another issue is that texts printed right-to-left in the source (where print direction is done using Unicode's control characters) are not wrapped correctly and may require manual placement of line breaks, or scripting their split in game.
* MIDI no longer plays on its own on Windows. For MIDI you (and your players) must install "sound banks" (also known as "sound font"). Please refer to this article: https://adventuregamestudio.github.io/ags-manual/MIDI-playback.html
* AudioChannel.Position and AudioChannel.Seek do not work for MIDI and MOD sounds. Try sticking to PositionMs and SeekMs for now.
* There are reports about Direct3D not being able to restore the fullscreen mode after alt+tabbing occasionaly.





Thanks to everyone who contributed to and tested this version!



#49
Many years ago, when the open source stage of AGS has just began, people were discussing means to improve it. Perhaps I was not the only one, but once I suggested to make a room contents explorer panel, similar to the Project Explorer, with a tree-like structure. I had Project Explorer as an example, but I recall that others also were suggesting art software as a reference (like Photoshop, with its groups and layers).

Unfortunately, tzachs, who was intending to work on this, had an opinion that another explorer-like panel would take too much extra space on screen. Somehow his idea was that the AGS UI is already too clogged. This is why he went the direction of Navigation bar, that we have today.

But this navigation bar turned to have a number of usability issues, and is difficult to customize too.

My suggestion is to revive the topic of a proper room explorer, and design one at least "on paper", defining which would be more convenient.

Summary

AGS 3.6.0 is another big change to AGS.
First of all, this release presents a SDL2-based engine. For about 2 decades AGS engine was based on Allegro 4 graphic library, which was discontinued somewhere in the early 2010-ies (only received few patches since). There was an intent to move to to Allegro 5 or SDL since, but for various reasons this task was continuously postponed. Now it's done.
Secondly the Editor and Engine now have full Unicode support. This means that you may use any language whatsoever in scripts, object descriptions and custom properties, as well as translations; so long as you also provide proper unicode fonts.
Third, we have finally expanded a list of platforms that the Editor can build for: now this includes Android and Web (Emscripten) port.

There are much more changes and improvements in this release, check out the full list of changes below.
Also, please be sure to read "Upgrading to AGS 3.6" topic in the manual: https://adventuregamestudio.github.io/ags-manual/UpgradeTo36.html



Changes in the Patch 4:

Editor:
- Export Game's Title into translations.
- Fixed Game.agf was not created after importing a 2.* game project (regression in 3.6.0).

Engine:
- Character.AnimationVolume property is now applied to the portrait animation as well.
- Removed few of the less important game messages from logging, because they may quickly clutter the log under some circumstances.
- Fixed when animating a character portrait, the first frame's linked sound is not played.
- Fixed IsSpeechVoxAvailable() returning positive result if run from IDE and Speech folder is empty.
- Fixed speech and messages were skipped by modifiers and other special keys (Ctrl, Alt, etc).
- Fixed crash occuring when you resize DynamicSprite while it is displayed on screen.
- Fixed audio clip started right before a ChangeRoom would not play until after the room changes.
- Fixed in Software display mode the room Overlays may not be properly covered by a walk-behind under very specific conditions.
- Fixed System.Log() would cause engine crash if there are more format placeholders than args.
- Fixed some game options that are not allowed to be changed at runtime could still be overwritten when restoring an old save, leading to a weird game behavior.


Changes in the Patch 3:

Editor:
- Don't error when loading a room file which has unsupported number of events, instead these will be cut out. This may let e.g. use room templates from newer versions of AGS.
- Sprite's default property is changed from deprecated Resolution setting to SourceFile.
- Fixed full spritefile recreation would write duplicate sprites into the spritefile, if game project (Game.agf file) contained multiple sprites with same ID for any reason (for example, if they were added by manually editing Game.agf).
- Fixed importing SCI fonts with >128 chars.
- Fixed font preview did not properly display characters with indexes 128-255.

Engine:
- Fixed "noloopcheck" script function modifier was not handled correctly sometimes.
- Fixed a button with inventory placeholder did not update immediately when the active inventory is set.
- Fixed textual GUIs were not redrawn immediately after a call to SetGameOption(OPT_RIGHTTOLEFT).


Changes in the Patch 2:

Common:
- Fixed a TTF font could cause a crash in the Editor or the Engine if the font renderer tries to draw a letter with higher number than the highest glyph number in the font.

Editor:
- Added "Restore all sprites..." command to the Sprite Manager's context menu (this duplicates the "File -> Recreate sprite file" menu command added previously).
- Refresh Sprite Manager after fully recreating a sprite file.
- Sprites will now hide their "Resolution" property if the game settings have "Allow relative asset resolutions" disabled. This is to avoid user's misuse of this property.
- Fixed a minor memory leak occuring when editing a tree item's label in Project Explorer.

Engine:
- Engine will now find and load plugins in the game dir when run from a different location.
- Fixed crash occuring if Character was told to FaceLocation while "Turn to face" game setting is enabled, and character's View does not have enough loops.
- Fixed Character resetting current non-blocking animation if it was ordered to Move, as soon as it arrives at destination.
- Fixed crash occuring if a GUI button was somehow set a negative NormalImage number.
- Fixed "bad script stack" error could be sometimes displayed if the game was aborted in the middle of running a script.


Changes in the Patch 1:

Editor:
- Fixed room's deprecated setting LegacyMusicVolumeAdjustment not applied correctly.

Engine:
- Fixed Room Objects whose dynamic sprite was deleted in "leave room" event becoming invisible during fade-out transition. Logically this has to happen, but historically they kept displaying until the transition end, so we restored this behavior for compatibility, and simply because there's no "after fade-out" event in the engine yet to delete these sprites.
- Fixed Game.StopAudio() fails to remove queued clips if no particular audio type id is requested.
- Fixed performance regression in the script related to long loops (regression in 3.6.0).
- Fixed memory leak occuring when printing text in Right-to-left mode (regression in 3.6.0).
- Fixed rare mistake during text wrapping which may occur if a Unicode text is cut in the middle of the word.
- Fixed playing certain WAVs caused game to freeze forever on exit.

Compatibility:
- Fixed frame-linked sounds not playing in the games made before 3.6.0.
- Allow game to call DynamicSprite.Create() with negative size, clamping it to 1x1.

Templates:
- In Sierra-style template fixed "mouse over" graphic for the "Load" icon.



What is new in 3.6.0

Common features:
- Full Unicode support for all game texts: game properties, scripts, translations, input.
  ASCII/ANSI mode is still working, for backwards compatibility. This may be configured in the game project.
- Extended sprite compression options: lossless storage optimization for 16- and 32-bit sprites; LZW compression option for sprites in addition to existing RLE compression.
- GUI controls may now be told to clip their contents, which means that nothing gets drawn outside of their borders (as defined by X, Y, Width, Height properties). The only exception is Sliders, which are more complicated.
- The historical TTF fonts' "fixup" that altered their height and vertical offset is now optional and works only if backwards compatible option is set.
- Max number of AudioChannels is now 16 (was 8).
- Removed game Cursors hard limit (was 20).
- Increased Room Objects limit to 256 (was 40).
- Discontinued "Windows Game Explorer" support in both Editor and Engine.

Editor:
- Editor requires .NET Framework 4.6 to run.
- Added Android build target support (requires "Android component" installed).
- Added Web/Emscripten build target support (requires "Web build component" installed).
- Expanded UI color theme format, support global color options and allow missing entries.
- Script editor works in unicode mode.
- Added "Text format" option in General Settings which lets switching between ASCII/ANSI and Unicode (UTF-8) modes. This defines which format the game texts will be written in, when saving the game project and compiling the game.
- Added "Use old-style keyboard handling" option to the General Settings, which lets select between classic key press handling and new one meant for unicode chars support in scripts.
- Supports compiling UTF-8 translations. TRS file now has "Encoding" setting that tells how to interpret this TRS text.
- Added support for building multiple speech voxes, by taking files from the Speech subfolders.
- Added support for adding custom files into the game package. This is done by assigning a list of directories to "Package custom data folder" option in General Settings.
- Editor now copies a acsetup.cfg file from the project's root folder (if one is provided by) as a base for generating default config file. Settings from Default Setup will be written over, but other found options won't be removed.
- Added "Sprite file compression" option in General Settings, replacing "Compress the sprite file" option. The new option allows a selection of compression algorithm used for sprites.
  Currently supported: None, RLE (old default compression) and LZW.
- Added "Enable sprite storage optimization" option to the General Settings, that permits the editor to repack sprites in a different storage format, reducing their disk size whenever possible. This option may be used alongside with the sprite compression. Note that this does not change how the sprites work in game.
- Added "GUI controls clip their contents" option to the General Settings.
- Added "TTF fonts height used in the game logic" option to the General Settings, that makes your game use real font's pixel height when arranging text and text-based UI elements, as opposed to the nominal font's size.
- Added "Touch to Mouse Emulation", "Touch to Mouse motion mode" and "Display FPS on Screen" to Default Setup. Removed few deprecated options.
- Added "TTF font adjustment" property to Fonts, as well as to General Settings where it serves as a project default for the new fonts. This property lets you choose between "no changes" and backward compatible TTF fixup meant to keep fonts made for AGS displayed as they were meant to.
- In the "Import TTF" dialog added a choice to import the size closest to the given pixel height.
- Fonts now have Auto Outline Style and Auto Outline Thickness properties.
- Fonts now have a readonly Family Name field, that lets user see the original name of a font they've imported (if available).
- Added IdleDelay property to Characters that lets you set time needed to pass before IdleView is activated. This is equivalent to the Character.SetIdleView script function.
- Added Character.IdleAnimationDelay property to let setup idle view's animation speed.
- Added Cursor.AnimationDelay property to let setup cursor's animation speed.
- The TextWindow edges now have distinct names in the dropdown list of the property grid.
- Rooms created from a Blank template will now have default background of a game's resolution.
- When creating new room objects they will now have their script names set to some default value.
- Added Room.BackgroundAnimationEnabled property to let have disabled animation on room load.
- Editor will now create an empty sprite file if one is missing in the game project. Any existing sprite descriptions in the project will be kept, letting user to reimport these from sources.
- Added "File -> Restore all sprites from sources" menu command.
- Added "Apply" button on editor's Preferences dialog.
- In Preferences replaced "Import Color Theme" with a "Open Theme Folder", as a temporary solution for managing theme files.
- Select script editor's font in the editor's Preferences.
- Added "Help" option to the editor pane's tab context menu.
- Upgraded script editor to Scintilla 3.21.1 and ScintillaNET 3.6.3.
- Cursor's position in script is now displayed on the status bar.
- Dialog scripts now too can open help topics for keywords or script functions under cursor on F1.
- Added zoom controls for the Sprite Manager, Character, Cursor, Inventory and View panes.
- Sprites may now be imported by drag'n'drop into the Sprite manager.
- In sprite manager's context menu added command "Create source files for all sprites with missing / external sources..."
- In sprite manager's context menu added (restored) command "Replace sprite using previous files".
  Also made "previous file" remembered consistently whenever a sprite is imported or replaced.
- In sprite manager's "export all" dialog added "skip if inside project's folder" option.
- In sprite manager's "export all" dialog added "reset tile settings" option.
- On the View pane the frames having set delay and linked sound will be now indicated with icons.
- Editor no longer errors and fails when opening a game project with some script files missing.
- Editor no longer errors on empty translations when compiling the game.
- Editor now exports values of the string type Custom Properties to translations.
- Editor no longer prevents exporting string arguments from Get/SetTextProperty calls to TRS file.
- Editor now cleanups spritefile on game load, identifying any data not referenced by the project and marking it for deletion.
- Fixed editor silently enabling all available Build Targets when upgrading a pre-3.4.0 project. This could be very inconvenient as there are several of them supported now.
- Fixed open folders in the Project Tree were collapsing whenever you create a new subfolder or change an object's name in properties.
- Fixed editor was not preventing from entering Character's and AudioClip's ScriptName too long for the engine to handle.
- Fixed Image and View properties in various objects were allowing negative values.
- Fixed some of the object previews (at least GUI) could crash if user entered a non-existing sprite's number as an Image property.
- Fixed editor displaying unhandled exception if the script which user is trying to open was missing. Instead it will now open a blank script.
- Fixed room editor was suggesting to save the modified room even if no changes were made.
- Fixed a recently imported sprite could be displayed incorrectly scaled up in the room editor for high-resolution games, if the "Allow relative asset resolutions" was enabled in General Settings, and the sprite 0 had "Resolution" property set to "Low".
- Fixed program crash occuring on sprite's import if failed to open a source file for any reason.
- Fixed View animation preview stopping at frame 100 (if loop contains over 100 frames).
- Fixed going to a "find all" result in dialog script did not highlight the found text, and sometimes did not scroll down to it.
- Fixed "Goto Definition" not working for Enums and Defines (macros).
- Fixed script autocomplete sometimes was not updated right after opening a script.
- Fixed script autocomplete for function calls was mistreating commas in strings and inline comments as if they were separating actual parameters.
- Fixed script autocomplete was not displaying members of extended structs if the parent struct was declared in another header.
- Fixed script autocomplete was not working for enum names.
- Fixed structs and enums were not highlighted if declared inside a script's body.
- Fixed in dialogs numbers inside names were incorrectly highlighted as numeric values.
- Fixed matching or mismatching braces were not highlighted consistently at all times in regular and dialog scripts.
- Fixed crash occuring when user was trying to set breakpoint on the very last line in script.
- Fixed few editor panes were not opening correct help topics in F1.
- (Possibly) fixed error message text in the runtime error popup could be drawn partially beyond the popup borders if the user's system has text scaling option enabled.

Compiler:
- Support unicode character literals.
- Support using float literals when defining default values for function arguments.
- Support hexadecimal number literals (e.g. "0xABCDEF").
- Removed 500-characters line limit.

Script API:
- Expanded `on_key_press` callback, now supports two parameters: key code and key modifier flags.
- In the new key handling mode `on_key_press` is called for each actual key press;
  e.g. combinations like Ctrl+Z will result in two `on_key_press` calls, one with eKeyCtrlLeft and second with eKeyZ; added support for "NEW_KEYINPUT_API" macro in scripts.
- Implemented new `on_text_input(int ch)` callback which is called when the engine receives a printable character. This callback is essential for handling unicode chars in script.
- Similarily, expanded `dialog_options_key_press` with the third `mod` argument, and implemented `dialog_options_text_input` callback for receiving unicode chars during the custom dialog options state.
- Implemented `dialog_options_close` callback which is called when custom dialog options are removed from the screen. This allows to perform any required cleanup.
- Added eEventEnterRoomAfterFadein event for `on_event` callback, which corresponds to "enter after fade-in" room event.
- Added eKey constants for Shift, Control and Alt keys.
- Added eKeyMod enum for key modifiers constants.
- String.AppendChar(), ReplaceChar() functions and String.Chars[] property are now working with the unicode characters.
- String.Format("%c") specifier will now be able to print unicode characters.
- Extended Button.Animate() to have blocking style, direction and starting frame parameters, thus matching other Animate commands (of Character and Object).
- Extended all Animate() commands by adding "volume" parameter, that defines volume of the frame-linked sounds for the duration of this animation.
- Added Character.AnimationVolume, defining volume of the frame-linked sounds.
- Added Character.IdleAnimationDelay to let control idle view's animation speed.
- Character.Scaling is no longer limited by a range of 5-200 (now supports 1-32767).
- Hotspot.Name and Object.Name may now be set in script.
- Added Object.ManualScaling and Object.Scaling.
- Deprecated Object.IgnoreScaling (use Object.ManualScaling instead).
- Object.SetView default loop & frame values are now 0 (was -1 which retained loop and frame indexes from the previous view, often unexpected to the user).
- DrawingSurface.DrawImage() and DrawSurface() now support optional source rect coordinates.
- Added functions for getting DrawingSurface of room masks: GetDrawingSurfaceForWalkableArea(), GetDrawingSurfaceForWalkbehind(), Hotspot.GetDrawingSurface(), Region.GetDrawingSurface().
- Added new delay parameter to Mouse.ChangeModeView() to let control cursor's animation speed.
- Added Game.ChangeSpeechVox() and Game.SpeechVoxFilename, support switching the voice-over pack.
- Added Mouse.AutoLock property that toggles automatic mouse lock inside the game window.
- Added Room.Exists().
- Added System.Log().
- Added SkipWait() that skips any active Wait() function.
- Added WaitMouse() to complement existing Wait functions.
- Added InputType enum which defines input devices and lets create their sets as flags.
- Added WaitInput(), a more generic and extendable function that accepts a combination of flags telling which input types to wait for.
- All Wait* functions now may have infinite timeout if you pass a negative timeout parameter.
- All Wait* functions now return the reason they were skipped: a combination of InputType flag and a respective key or button code.
- Added GUIControl.Transparency property.
- Added Overlay.CreateRoomGraphical and CreateRoomTextual. Use these two functions to create "room overlays": that is - overlays that display a sprite inside the room, sorted among other room objects, characters and walk-behinds.
- Added readonly Overlay.InRoom property that tells if this is a room or screen overlay.
- Extended Overlay.CreateGraphical() with a new "clone" parameter that tells whether to assign a sprite index, or make a sprite's copy owned exclusively by this overlay. The former will save program memory but make overlay update if the sprite is edited later. The latter is meant primarily for backwards compatibility.
  Overlay.CreateRoomGraphical has the same param.
- Added Overlay.Graphic property that lets you change overlay's sprite after it's created.
- Added Overlay.Width and Height properties, that let you freely scale existing Overlay.
- Added readonly Overlay.GraphicWidth and GraphicHeight properties that let read original overlay's graphic size, as not all overlays hold a sprite reference (e.g. textual overlays).
- Added Overlay.Transparency property.
- Added Overlay.ZOrder property that lets you sort Overlays among themselves and other objects in the same "game layer": screen overlays are sorted among GUI, while room overlays are sorted among room objects, characters and walk-behinds.
- Added Speech.TextOverlay and Speech.PortraitOverlay for accessing blocking speech overlay and portrait overlay respectively.
- Added Game.BlockingWaitSkipped which tells the result of the last blocking wait skipping, also including result of the blocking speech skipping.
- SkipSpeechStyle now supports eSkipNone mode; when used it will disable any kind of skipping, such speech can be only skipped by a direct command from script.
- Extended Screen.ScreenToRoomPoint() with an optional "restrictToViewport" argument, which lets to choose whether tests over empty place result in conversion through the default viewport or a null pointer.
- Added AudioClip.PlayOnChannel().
- Added AudioChannel.Pause() and Resume() functions, and IsPaused property.
- Added AudioChannel.SeekMs(), complementing PositionMs (as the Seek() function interprets position differently depending on the audio format).
- PlayVideo() now supports an option to play both game's and video's audio track simultaneously.
- Added File.WriteRawInt() to complement ReadRawInt().
- File paths in script now support $DATA$ token, which tells to read files from the game package. This only works for read operations. Functions that support this token currently are:
  File.Open(), DynamicSprite.CreateFromFile(), ListBox.FillDirList().
- Debug(2, 0) command that displayed walkable areas is superceded by Debug(2, n), where "n" is a mask type: 0 - none, 1 - hotspots, 2 - walkbehinds, 3 - walkable areas, 4 - regions. This command also works as a toggle switch, calling it with the same mask index will turn it off.
- Debug(5, n) command that displayed character's walk paths now also works as a toggle switch.

Engine:
- New SDL2-based backend for graphics, audio and input.
- Hqx graphic filters discontinued (could be temporary).
- Windows-only DirectMedia video playback discontinued (could be temporary).
  Only OGG/OGV videos are kept supported at this point.
- Support resizing game window on desktop systems.
- Support "borderless full-screen window" mode in addition to the real (exclusive) fullscreen.
- Support for switching vertical sync at runtime with Direct3D/OpenGL renderers. Also enable vsync in windowed mode too.
- Unicode (UTF-8) text support: engine can now switch between ASCII and UTF-8 text mode. This is controlled by both game's OPT_GAMETEXTENCODING setting and translation's "Encoding" setting: they tells whether to interpret game texts as UTF-8 or ASCII/ANSI.
- Support optional translation's "GameEncoding" setting: it hints the original game's codepage to help with their conversion. This is mostly meant for translating existing older (ANSI) games.
- Engine now supports using real pixel height of the TTF fonts when arranging text and UI elements on screen; using nominal import size of the font is used as a compatible mode for the old games.
- Also supports separate "normal" and backward compatible "fixup" modes when initializing TTF fonts, letting to display both common TTFs and ones made specifically for AGS in the past to display as they were meant to be.
- Supports scripts using functions and variables from any other scripts, regardless of the script module order in the project.
- Removed limit of simultaneous Button animations.
- Removed limit of Character followers.
- Removed Overlay limit.
- Character.SetWalkSpeed() is no longer restricted by an arbitrary limit of 50.
- Process character's idle view based on real game speed, not hardcoded 40 fps.
- Improved file writing times (e.g. when doing a game save) by using buffered file stream. Initial tests showed 50% faster file writing.
- Engine now renders GUI controls as separate textures when using hardware accelerated renderers. This may significantly improve performance in the high-resolution games and games with large number of GUI elements on screen.
- Engine now shares the video texture data for all game objects on screen sharing same sprite. This improves performance in case there are multiple objects which use same image.
- Various performance optimizations for both raw drawing and texture updates (Direct3D/OpenGL).
- Engine now ensures that in threaded audio mode the AudioChannel's state only changes once the game is updated, and not while the game script is running. This prevents situations when the clip could begin playing before all properties are set in script, or when AudioChannel's properties' values (such as Position) could change while running a game script.
- 24-bit wav PCM support, comes with the new sound library.
- File.ReadRawLineBack() now always reads full line, and not limited to 200 characters anymore.
- Debug displays, such as showing room mask and character walk paths, are now implemented as non-blocking translucent overlays, allowing you to keep playing the game while they are on.
- Implemented debug key controls for calling a built-in save and restore game dialogs. These controls have to be set in user config as "save_game_key" and "restore_game_key" in "[override]" category. These may be used by testers if the game is missing a save function or one is bugged.
- Engine now supports loading compiled scripts as separate files packed along with the game, along with those embedded into the main game data or inside room files.
- Engine no longer bails out with error if the chosen translation cannot be loaded on startup.
- When reporting script errors, engine will print callstack for all the active script "threads": for example, if there's Wait() function called and error happened in repeatedly_execute_always, then it will print both actual error's location, and Wait() call's location.
- Engine config now has graphic modes defined as a simplier string options: "[graphics] fullscreen" for the fullscreen mode setup, and "[graphics] window" for the windowed.
  Fullscreen option can explicitly define a "borderless full-screen window" mode.
- Added "emul_mouse_mode" and "emul_mouse_relative" options to config in "[touch]" category.
- Added "cache_size" and "stream_threshold" options to config in "[sound]" category, they setup the rules for sound caching and choosing whether to load a clip fully into mem or stream one.
- Added "load_latest_save" and "show_fps" options to config in "[misc]" category.
- Added "background" option to config in "[misc]" category, that defines the starting run-in-background (aka multitasking) mode (may later be changed by SetMultitaskingMode()).
  Added "--background" command line option for the same purpose.
- Added "--sdl-log" command line option for setting up SDL2 library output verbosity. The engine log config now has a new "sdl" group meant for SDL2 messages.
- Support "--user-conf-dir" command-line arg (and "user_conf_dir" config option) superceding "--localuserconf"; the new option directly tells the location of user config file.
- Path related command-line and config options, - such as "shared_data_dir", "user_data_dir" and "user_conf_dir", now support $GAMENAME$ token in path which is resolved to the game's title.
- Added "--clear-cache-on-room-change" command-line arg (and similar config option).
- Don't error when DrawingSurface.DrawImage has bad transparency parameter (warning instead).
- Don't error when detecting bad format in File.Read* functions (warning instead).
- Added stubs for agsshell plugin (a contemporary cross-platform variant of ags_shell).
- Added stubs for agsappopenurl plugin.
- Fixed potential crashes if a room-related API function has been called in "game_start"; this is achieved by having a dummy room placeholder object. Still results of such calls are undefined and should not be relied upon.
- Fixed potential crash on room load if the walkable area mask contained color values above the supported range.
- Fixed dialog script's "goto-previous" command not working if used from the first sub-topic run using "goto-dialog" (a very-very old bug).
- Fixed AGS_EngineInitGfx plugin callback was not called during OpenGL renderer initialization.
- Fixed Direct3D/OpenGL renderers were displaying plugin's raw drawings in a wrong position in the scrolling rooms, if the drawing was done on AGSE_PRESCREENDRAW or AGSE_POSTROOMDRAW events.
- Fixed overlay may fail to be created sometimes, if previously another overlay had been forcefully removed when changing rooms (this is an ancient bug which existed for many years).
- Fixed ListBox.RowCount reporting 0 if called before the control was displayed once.
- Fixed GetTextWidth would still return a size of an outline for an empty text string.
- Fixed text may be misaligned in gui controls, as its outline thickness is not counted.
- Fixed some TTF fonts could be cut at the bottom when the speech is displayed.
- Fixed scheduled sound fadeout effect was not cancelled by skipping a cutscene.
- Fixed OGV Theora videos positioned incorrectly if they have certain sizes or aspect ratios.
- Fixed game fps sped up if SetGameSpeed() is called repeatedly in game script.
- Fixed game not reacting to system close commands when stuck in script, which made it impossible
  to close the "hanging" game by usual means (other than terminating the process).

Engine Plugin API:
- Added IAGSEngine::GetGameInfo() function which returns information about the game, such as its title and GUID.
- Added new render callback AGSE_POSTROOMDRAW, for handling drawing inside the room above all room objects.
- Added IAGSFontRenderer2 interface, expanding the original font renderer interface, improving font plugins support.
- Added ReplaceFontRenderer2() and NotifyFontUpdated() functions.

Compatibility:
- Fallback to the first loop with frames if current character's loop does not have any.
- Use the dummy frame if current character's speech view loop does not have any.
- Ignore character having view/loop with no frames while it's not in the current room.
- Legacy behavior of MoveCharacterBlocking's return value.
- Fixed walkable area's continuous scaling was broken for high-res rooms in old games.
- In pre-3.* games force player to walkable area after changing rooms, this is to emulate an unintentional effect created by the old engines.
- Fixed pre-3.4.1 anti-aliased TTF fonts display (their vertical position was broken).
- For pre-3.5.0 games support old behavior of coincidental dynamic sprite replacement on GUI backgrounds (and few other places) without explicit assignment; that is - when the new DynamicSprite is created right after deleting an old one.
- Support Label.TextAlignment with legacy alignment constants for pre-3.5.0 games made with the custom engine from "Clifftop Games".
- Support native resolution hack for games made with "Clifftop Games" custom engine, where 640x400 games are run as 640x360.

Android:
- Rewrote universal AGS game launcher/player using up-to-date Google guidelines. The former "launcher" is now called "AGS Player".
- Implemented single game project template meant for building your own signed APK.
- Implemented two touch-to-mouse control scheme (selectable in config), for one finger emulating LMB only, and for two fingers emulating LMB and RMB.
- Support relative motion speed setting for touch-to-mouse emulation.
- In AGS Player added "Browse" button to the game folder selection, which opens default system file picker.
- AGS Player now searches for games recursively, in all the subfolders.
- AGS Player now has preference button per each game, which opens individual game's settings.

OSX:
- OpenGL renderer is now supported on MacOS.

Web / Emscripten:
- Initial port release.

Windows:
- Installer will create program links with three-digit version in the name.

Plugins:
- Added SpriteFont plugin to the list of builtins, for ports that use ones.
  SpriteFont plugin is updated to support custom "Clifftop Games" font variants.

WinSetup:
- Added "Fullscreen as borderless window" checkbox.
- Remade sound options to reflect the move to the new audio system in the engine.




Known issues

* Although Unicode text is supported overall, some languages may still not be printed correctly automatically. Firstly, those that require "letter linking", such as Arabic or Persian, do not have the proper linking on its own. This may be worked around using special text converters and fonts. Another issue is that texts printed right-to-left in the source (where print direction is done using Unicode's control characters) are not wrapped correctly and may require manual placement of line breaks, or scripting their split in game.
* MIDI no longer plays on its own on Windows. For MIDI you (and your players) must install "sound banks" (also known as "sound font"). Please refer to this article: https://adventuregamestudio.github.io/ags-manual/MIDI-playback.html
* AudioChannel.Position and AudioChannel.Seek do not work for MIDI and MOD sounds. Try sticking to PositionMs and SeekMs for now.
* There are reports about Direct3D not being able to restore the fullscreen mode after alt+tabbing occasionaly.





Thanks to everyone who contributed to and tested this version!

We had a thought to optionally support a Sierra-style speech view with character portraits in the default game templates. But for that we'd need to have Roger's portraits.

If anybody is willing to draw a portrait animation for the Roger character, something simple, consisting of < 10 frames, please contact us here in this thread, or here in this suggestion thread on github:
https://github.com/adventuregamestudio/ags-template-source/issues/36

Please keep in mind that the style should match the resolution and art style of the default template assets, more or less.

Perhaps, it would be a good idea to post this work in Critics Lounge first, to get peoples reaction.

There's a peculiar problem that I'm currently trying to solve.

Historically object's animation in AGS is designed so that you have to call Object.SetView first in order to assign a view, and only then Animate in order to begin animation.

This is in a way similar to Character's LockView/Animate pair, but there's a caveat: for some reason, unlike Character.LockView, Object.SetView also triggers a linked sound frame, while for Character this is only done when Animation starts.

I don't know if this is intentional or not. This may be related to Object.SetView internally passing to an older function called SetObjectFrame, which possibly could have been used as a step-by-step replacement to animation in older versions of AGS.

But this behavior conflicts with Animate, because apparently, a pair of SetView/Animate will cause 2 frames, or same frame to be processed 2 times in a quick succession. By "processed" I mean anything related to the frame's activation. Currently this is playing a linked sound.

To clarify: if you have a sound linked to a frame 0 of the given loop, then setting object to that frame with SetView, and then calling Animate will play that sound twice. Normally we do not notice that because the sounds will play in sync. But it may be found out if you print the state of AudioChannels somewhere in real time.

With the addition of "volume" parameter to Animate() function in 3.6.0 this issue becomes more complicated, because user may want to animate an object with one volume, but SetView will play it with a full volume.

At first I thought that adding AnimationVolume property to Object will solve this (similar to one added to Character type), but then realized that this does not solve this logical conflict between SetView and Animate at all: because both object's AnimationVolume and current Animate's vol param are relative factors that are consecutively applied to the default volume (i.e.: final_volume = 100% * AnimationVolume % * current Animate's volume %). As a result SetView will play a sound with one volume (not yet affected by Animate's parameter), while the rest of the frames will be once again played with other volume.
The only way to mitigate this would be to always run Animate with volume param = 100, which effectively makes this parameter useless...


To summarize this conflict:
- You must call SetView if you want to Animate an object;
- At the same time calling SetView processes the current frame's behavior regardless of whether you are planning to animate or not.


I'd like to find some solution for this, because it's wrong and annoying. Ideally this solution should be something applicable to the 3.6.1 release, as it's already causing trouble to users (this is how I found this problem).

Summary

AGS 3.6.0 is another big change to AGS.
First of all, this release presents a SDL2-based engine. For about 2 decades AGS engine was based on Allegro 4 graphic library, which was discontinued somewhere in the early 2010-ies (only received few patches since). There was an intent to move to to Allegro 5 or SDL since, but for various reasons this task was continuously postponed. Now it's done.
Secondly the Editor and Engine now have full Unicode support. This means that you may use any language whatsoever in scripts, object descriptions and custom properties, as well as translations; so long as you also provide proper unicode fonts.
Third, we have finally expanded a list of platforms that the Editor can build for: now this includes Android and Web (Emscripten) port.

There are much more changes and improvements in this release, check out the full list of changes below.
Also, please be sure to read "Upgrading to AGS 3.6" topic in the manual: https://adventuregamestudio.github.io/ags-manual/UpgradeTo36.html



Changes in the Patch 3:

Editor:
 - Don't error when loading a room file which has unsupported number of events, instead these will be cut out. This may let e.g. use room templates from newer versions of AGS.
 - Sprite's default property is changed from deprecated Resolution setting to SourceFile.
 - Fixed full spritefile recreation would write duplicate sprites into the spritefile, if game project (Game.agf file) contained multiple sprites with same ID for any reason (for example, if they were added by manually editing Game.agf).
 - Fixed importing SCI fonts with >128 chars.
 - Fixed font preview did not properly display characters with indexes 128-255.

Engine:
 - Fixed "noloopcheck" script function modifier was not handled correctly sometimes.
 - Fixed a button with inventory placeholder did not update immediately when the active inventory is set.
 - Fixed textual GUIs were not redrawn immediately after a call to SetGameOption(OPT_RIGHTTOLEFT).


Changes in the Patch 2:

Common:
- Fixed a TTF font could cause a crash in the Editor or the Engine if the font renderer tries to draw a letter with higher number than the highest glyph number in the font.

Editor:
- Added "Restore all sprites..." command to the Sprite Manager's context menu (this duplicates the "File -> Recreate sprite file" menu command added previously).
- Refresh Sprite Manager after fully recreating a sprite file.
- Sprites will now hide their "Resolution" property if the game settings have "Allow relative asset resolutions" disabled. This is to avoid user's misuse of this property.
- Fixed a minor memory leak occuring when editing a tree item's label in Project Explorer.

Engine:
- Engine will now find and load plugins in the game dir when run from a different location.
- Fixed crash occuring if Character was told to FaceLocation while "Turn to face" game setting is enabled, and character's View does not have enough loops.
- Fixed Character resetting current non-blocking animation if it was ordered to Move, as soon as it arrives at destination.
- Fixed crash occuring if a GUI button was somehow set a negative NormalImage number.
- Fixed "bad script stack" error could be sometimes displayed if the game was aborted in the middle of running a script.


Changes in the Patch 1:

Editor:
- Fixed room's deprecated setting LegacyMusicVolumeAdjustment not applied correctly.

Engine:
- Fixed Room Objects whose dynamic sprite was deleted in "leave room" event becoming invisible during fade-out transition. Logically this has to happen, but historically they kept displaying until the transition end, so we restored this behavior for compatibility, and simply because there's no "after fade-out" event in the engine yet to delete these sprites.
- Fixed Game.StopAudio() fails to remove queued clips if no particular audio type id is requested.
- Fixed performance regression in the script related to long loops (regression in 3.6.0).
- Fixed memory leak occuring when printing text in Right-to-left mode (regression in 3.6.0).
- Fixed rare mistake during text wrapping which may occur if a Unicode text is cut in the middle of the word.
- Fixed playing certain WAVs caused game to freeze forever on exit.

Compatibility:
- Fixed frame-linked sounds not playing in the games made before 3.6.0.
- Allow game to call DynamicSprite.Create() with negative size, clamping it to 1x1.

Templates:
- In Sierra-style template fixed "mouse over" graphic for the "Load" icon.



What is new in 3.6.0

Common features:
- Full Unicode support for all game texts: game properties, scripts, translations, input.
  ASCII/ANSI mode is still working, for backwards compatibility. This may be configured in the game project.
- Extended sprite compression options: lossless storage optimization for 16- and 32-bit sprites; LZW compression option for sprites in addition to existing RLE compression.
- GUI controls may now be told to clip their contents, which means that nothing gets drawn outside of their borders (as defined by X, Y, Width, Height properties). The only exception is Sliders, which are more complicated.
- The historical TTF fonts' "fixup" that altered their height and vertical offset is now optional and works only if backwards compatible option is set.
- Max number of AudioChannels is now 16 (was 8).
- Removed game Cursors hard limit (was 20).
- Increased Room Objects limit to 256 (was 40).
- Discontinued "Windows Game Explorer" support in both Editor and Engine.

Editor:
- Editor requires .NET Framework 4.6 to run.
- Added Android build target support (requires "Android component" installed).
- Added Web/Emscripten build target support (requires "Web build component" installed).
- Expanded UI color theme format, support global color options and allow missing entries.
- Script editor works in unicode mode.
- Added "Text format" option in General Settings which lets switching between ASCII/ANSI and Unicode (UTF-8) modes. This defines which format the game texts will be written in, when saving the game project and compiling the game.
- Added "Use old-style keyboard handling" option to the General Settings, which lets select between classic key press handling and new one meant for unicode chars support in scripts.
- Supports compiling UTF-8 translations. TRS file now has "Encoding" setting that tells how to interpret this TRS text.
- Added support for building multiple speech voxes, by taking files from the Speech subfolders.
- Added support for adding custom files into the game package. This is done by assigning a list of directories to "Package custom data folder" option in General Settings.
- Editor now copies a acsetup.cfg file from the project's root folder (if one is provided by) as a base for generating default config file. Settings from Default Setup will be written over, but other found options won't be removed.
- Added "Sprite file compression" option in General Settings, replacing "Compress the sprite file" option. The new option allows a selection of compression algorithm used for sprites.
  Currently supported: None, RLE (old default compression) and LZW.
- Added "Enable sprite storage optimization" option to the General Settings, that permits the editor to repack sprites in a different storage format, reducing their disk size whenever possible. This option may be used alongside with the sprite compression. Note that this does not change how the sprites work in game.
- Added "GUI controls clip their contents" option to the General Settings.
- Added "TTF fonts height used in the game logic" option to the General Settings, that makes your game use real font's pixel height when arranging text and text-based UI elements, as opposed to the nominal font's size.
- Added "Touch to Mouse Emulation", "Touch to Mouse motion mode" and "Display FPS on Screen" to Default Setup. Removed few deprecated options.
- Added "TTF font adjustment" property to Fonts, as well as to General Settings where it serves as a project default for the new fonts. This property lets you choose between "no changes" and backward compatible TTF fixup meant to keep fonts made for AGS displayed as they were meant to.
- In the "Import TTF" dialog added a choice to import the size closest to the given pixel height.
- Fonts now have Auto Outline Style and Auto Outline Thickness properties.
- Fonts now have a readonly Family Name field, that lets user see the original name of a font they've imported (if available).
- Added IdleDelay property to Characters that lets you set time needed to pass before IdleView is activated. This is equivalent to the Character.SetIdleView script function.
- Added Character.IdleAnimationDelay property to let setup idle view's animation speed.
- Added Cursor.AnimationDelay property to let setup cursor's animation speed.
- The TextWindow edges now have distinct names in the dropdown list of the property grid.
- Rooms created from a Blank template will now have default background of a game's resolution.
- When creating new room objects they will now have their script names set to some default value.
- Added Room.BackgroundAnimationEnabled property to let have disabled animation on room load.
- Editor will now create an empty sprite file if one is missing in the game project. Any existing sprite descriptions in the project will be kept, letting user to reimport these from sources.
- Added "File -> Restore all sprites from sources" menu command.
- Added "Apply" button on editor's Preferences dialog.
- In Preferences replaced "Import Color Theme" with a "Open Theme Folder", as a temporary solution for managing theme files.
- Select script editor's font in the editor's Preferences.
- Added "Help" option to the editor pane's tab context menu.
- Upgraded script editor to Scintilla 3.21.1 and ScintillaNET 3.6.3.
- Cursor's position in script is now displayed on the status bar.
- Dialog scripts now too can open help topics for keywords or script functions under cursor on F1.
- Added zoom controls for the Sprite Manager, Character, Cursor, Inventory and View panes.
- Sprites may now be imported by drag'n'drop into the Sprite manager.
- In sprite manager's context menu added command "Create source files for all sprites with missing / external sources..."
- In sprite manager's context menu added (restored) command "Replace sprite using previous files".
  Also made "previous file" remembered consistently whenever a sprite is imported or replaced.
- In sprite manager's "export all" dialog added "skip if inside project's folder" option.
- In sprite manager's "export all" dialog added "reset tile settings" option.
- On the View pane the frames having set delay and linked sound will be now indicated with icons.
- Editor no longer errors and fails when opening a game project with some script files missing.
- Editor no longer errors on empty translations when compiling the game.
- Editor now exports values of the string type Custom Properties to translations.
- Editor no longer prevents exporting string arguments from Get/SetTextProperty calls to TRS file.
- Editor now cleanups spritefile on game load, identifying any data not referenced by the project and marking it for deletion.
- Fixed editor silently enabling all available Build Targets when upgrading a pre-3.4.0 project. This could be very inconvenient as there are several of them supported now.
- Fixed open folders in the Project Tree were collapsing whenever you create a new subfolder or change an object's name in properties.
- Fixed editor was not preventing from entering Character's and AudioClip's ScriptName too long for the engine to handle.
- Fixed Image and View properties in various objects were allowing negative values.
- Fixed some of the object previews (at least GUI) could crash if user entered a non-existing sprite's number as an Image property.
- Fixed editor displaying unhandled exception if the script which user is trying to open was missing. Instead it will now open a blank script.
- Fixed room editor was suggesting to save the modified room even if no changes were made.
- Fixed a recently imported sprite could be displayed incorrectly scaled up in the room editor for high-resolution games, if the "Allow relative asset resolutions" was enabled in General Settings, and the sprite 0 had "Resolution" property set to "Low".
- Fixed program crash occuring on sprite's import if failed to open a source file for any reason.
- Fixed View animation preview stopping at frame 100 (if loop contains over 100 frames).
- Fixed going to a "find all" result in dialog script did not highlight the found text, and sometimes did not scroll down to it.
- Fixed "Goto Definition" not working for Enums and Defines (macros).
- Fixed script autocomplete sometimes was not updated right after opening a script.
- Fixed script autocomplete for function calls was mistreating commas in strings and inline comments as if they were separating actual parameters.
- Fixed script autocomplete was not displaying members of extended structs if the parent struct was declared in another header.
- Fixed script autocomplete was not working for enum names.
- Fixed structs and enums were not highlighted if declared inside a script's body.
- Fixed in dialogs numbers inside names were incorrectly highlighted as numeric values.
- Fixed matching or mismatching braces were not highlighted consistently at all times in regular and dialog scripts.
- Fixed crash occuring when user was trying to set breakpoint on the very last line in script.
- Fixed few editor panes were not opening correct help topics in F1.
- (Possibly) fixed error message text in the runtime error popup could be drawn partially beyond the popup borders if the user's system has text scaling option enabled.

Compiler:
- Support unicode character literals.
- Support using float literals when defining default values for function arguments.
- Support hexadecimal number literals (e.g. "0xABCDEF").
- Removed 500-characters line limit.

Script API:
- Expanded `on_key_press` callback, now supports two parameters: key code and key modifier flags.
- In the new key handling mode `on_key_press` is called for each actual key press;
  e.g. combinations like Ctrl+Z will result in two `on_key_press` calls, one with eKeyCtrlLeft and second with eKeyZ; added support for "NEW_KEYINPUT_API" macro in scripts.
- Implemented new `on_text_input(int ch)` callback which is called when the engine receives a printable character. This callback is essential for handling unicode chars in script.
- Similarily, expanded `dialog_options_key_press` with the third `mod` argument, and implemented `dialog_options_text_input` callback for receiving unicode chars during the custom dialog options state.
- Implemented `dialog_options_close` callback which is called when custom dialog options are removed from the screen. This allows to perform any required cleanup.
- Added eEventEnterRoomAfterFadein event for `on_event` callback, which corresponds to "enter after fade-in" room event.
- Added eKey constants for Shift, Control and Alt keys.
- Added eKeyMod enum for key modifiers constants.
- String.AppendChar(), ReplaceChar() functions and String.Chars[] property are now working with the unicode characters.
- String.Format("%c") specifier will now be able to print unicode characters.
- Extended Button.Animate() to have blocking style, direction and starting frame parameters, thus matching other Animate commands (of Character and Object).
- Extended all Animate() commands by adding "volume" parameter, that defines volume of the frame-linked sounds for the duration of this animation.
- Added Character.AnimationVolume, defining volume of the frame-linked sounds.
- Added Character.IdleAnimationDelay to let control idle view's animation speed.
- Character.Scaling is no longer limited by a range of 5-200 (now supports 1-32767).
- Hotspot.Name and Object.Name may now be set in script.
- Added Object.ManualScaling and Object.Scaling.
- Deprecated Object.IgnoreScaling (use Object.ManualScaling instead).
- Object.SetView default loop & frame values are now 0 (was -1 which retained loop and frame indexes from the previous view, often unexpected to the user).
- DrawingSurface.DrawImage() and DrawSurface() now support optional source rect coordinates.
- Added functions for getting DrawingSurface of room masks: GetDrawingSurfaceForWalkableArea(), GetDrawingSurfaceForWalkbehind(), Hotspot.GetDrawingSurface(), Region.GetDrawingSurface().
- Added new delay parameter to Mouse.ChangeModeView() to let control cursor's animation speed.
- Added Game.ChangeSpeechVox() and Game.SpeechVoxFilename, support switching the voice-over pack.
- Added Mouse.AutoLock property that toggles automatic mouse lock inside the game window.
- Added Room.Exists().
- Added System.Log().
- Added SkipWait() that skips any active Wait() function.
- Added WaitMouse() to complement existing Wait functions.
- Added InputType enum which defines input devices and lets create their sets as flags.
- Added WaitInput(), a more generic and extendable function that accepts a combination of flags telling which input types to wait for.
- All Wait* functions now may have infinite timeout if you pass a negative timeout parameter.
- All Wait* functions now return the reason they were skipped: a combination of InputType flag and a respective key or button code.
- Added GUIControl.Transparency property.
- Added Overlay.CreateRoomGraphical and CreateRoomTextual. Use these two functions to create "room overlays": that is - overlays that display a sprite inside the room, sorted among other room objects, characters and walk-behinds.
- Added readonly Overlay.InRoom property that tells if this is a room or screen overlay.
- Extended Overlay.CreateGraphical() with a new "clone" parameter that tells whether to assign a sprite index, or make a sprite's copy owned exclusively by this overlay. The former will save program memory but make overlay update if the sprite is edited later. The latter is meant primarily for backwards compatibility.
  Overlay.CreateRoomGraphical has the same param.
- Added Overlay.Graphic property that lets you change overlay's sprite after it's created.
- Added Overlay.Width and Height properties, that let you freely scale existing Overlay.
- Added readonly Overlay.GraphicWidth and GraphicHeight properties that let read original overlay's graphic size, as not all overlays hold a sprite reference (e.g. textual overlays).
- Added Overlay.Transparency property.
- Added Overlay.ZOrder property that lets you sort Overlays among themselves and other objects in the same "game layer": screen overlays are sorted among GUI, while room overlays are sorted among room objects, characters and walk-behinds.
- Added Speech.TextOverlay and Speech.PortraitOverlay for accessing blocking speech overlay and portrait overlay respectively.
- Added Game.BlockingWaitSkipped which tells the result of the last blocking wait skipping, also including result of the blocking speech skipping.
- SkipSpeechStyle now supports eSkipNone mode; when used it will disable any kind of skipping, such speech can be only skipped by a direct command from script.
- Extended Screen.ScreenToRoomPoint() with an optional "restrictToViewport" argument, which lets to choose whether tests over empty place result in conversion through the default viewport or a null pointer.
- Added AudioClip.PlayOnChannel().
- Added AudioChannel.Pause() and Resume() functions, and IsPaused property.
- Added AudioChannel.SeekMs(), complementing PositionMs (as the Seek() function interprets position differently depending on the audio format).
- PlayVideo() now supports an option to play both game's and video's audio track simultaneously.
- Added File.WriteRawInt() to complement ReadRawInt().
- File paths in script now support $DATA$ token, which tells to read files from the game package. This only works for read operations. Functions that support this token currently are:
  File.Open(), DynamicSprite.CreateFromFile(), ListBox.FillDirList().
- Debug(2, 0) command that displayed walkable areas is superceded by Debug(2, n), where "n" is a mask type: 0 - none, 1 - hotspots, 2 - walkbehinds, 3 - walkable areas, 4 - regions. This command also works as a toggle switch, calling it with the same mask index will turn it off.
- Debug(5, n) command that displayed character's walk paths now also works as a toggle switch.

Engine:
- New SDL2-based backend for graphics, audio and input.
- Hqx graphic filters discontinued (could be temporary).
- Windows-only DirectMedia video playback discontinued (could be temporary).
  Only OGG/OGV videos are kept supported at this point.
- Support resizing game window on desktop systems.
- Support "borderless full-screen window" mode in addition to the real (exclusive) fullscreen.
- Support for switching vertical sync at runtime with Direct3D/OpenGL renderers. Also enable vsync in windowed mode too.
- Unicode (UTF-8) text support: engine can now switch between ASCII and UTF-8 text mode. This is controlled by both game's OPT_GAMETEXTENCODING setting and translation's "Encoding" setting: they tells whether to interpret game texts as UTF-8 or ASCII/ANSI.
- Support optional translation's "GameEncoding" setting: it hints the original game's codepage to help with their conversion. This is mostly meant for translating existing older (ANSI) games.
- Engine now supports using real pixel height of the TTF fonts when arranging text and UI elements on screen; using nominal import size of the font is used as a compatible mode for the old games.
- Also supports separate "normal" and backward compatible "fixup" modes when initializing TTF fonts, letting to display both common TTFs and ones made specifically for AGS in the past to display as they were meant to be.
- Supports scripts using functions and variables from any other scripts, regardless of the script module order in the project.
- Removed limit of simultaneous Button animations.
- Removed limit of Character followers.
- Removed Overlay limit.
- Character.SetWalkSpeed() is no longer restricted by an arbitrary limit of 50.
- Process character's idle view based on real game speed, not hardcoded 40 fps.
- Improved file writing times (e.g. when doing a game save) by using buffered file stream. Initial tests showed 50% faster file writing.
- Engine now renders GUI controls as separate textures when using hardware accelerated renderers. This may significantly improve performance in the high-resolution games and games with large number of GUI elements on screen.
- Engine now shares the video texture data for all game objects on screen sharing same sprite. This improves performance in case there are multiple objects which use same image.
- Various performance optimizations for both raw drawing and texture updates (Direct3D/OpenGL).
- Engine now ensures that in threaded audio mode the AudioChannel's state only changes once the game is updated, and not while the game script is running. This prevents situations when the clip could begin playing before all properties are set in script, or when AudioChannel's properties' values (such as Position) could change while running a game script.
- 24-bit wav PCM support, comes with the new sound library.
- File.ReadRawLineBack() now always reads full line, and not limited to 200 characters anymore.
- Debug displays, such as showing room mask and character walk paths, are now implemented as non-blocking translucent overlays, allowing you to keep playing the game while they are on.
- Implemented debug key controls for calling a built-in save and restore game dialogs. These controls have to be set in user config as "save_game_key" and "restore_game_key" in "[override]" category. These may be used by testers if the game is missing a save function or one is bugged.
- Engine now supports loading compiled scripts as separate files packed along with the game, along with those embedded into the main game data or inside room files.
- Engine no longer bails out with error if the chosen translation cannot be loaded on startup.
- When reporting script errors, engine will print callstack for all the active script "threads": for example, if there's Wait() function called and error happened in repeatedly_execute_always, then it will print both actual error's location, and Wait() call's location.
- Engine config now has graphic modes defined as a simplier string options: "[graphics] fullscreen" for the fullscreen mode setup, and "[graphics] window" for the windowed.
  Fullscreen option can explicitly define a "borderless full-screen window" mode.
- Added "emul_mouse_mode" and "emul_mouse_relative" options to config in "[touch]" category.
- Added "cache_size" and "stream_threshold" options to config in "[sound]" category, they setup the rules for sound caching and choosing whether to load a clip fully into mem or stream one.
- Added "load_latest_save" and "show_fps" options to config in "[misc]" category.
- Added "background" option to config in "[misc]" category, that defines the starting run-in-background (aka multitasking) mode (may later be changed by SetMultitaskingMode()).
  Added "--background" command line option for the same purpose.
- Added "--sdl-log" command line option for setting up SDL2 library output verbosity. The engine log config now has a new "sdl" group meant for SDL2 messages.
- Support "--user-conf-dir" command-line arg (and "user_conf_dir" config option) superceding "--localuserconf"; the new option directly tells the location of user config file.
- Path related command-line and config options, - such as "shared_data_dir", "user_data_dir" and "user_conf_dir", now support $GAMENAME$ token in path which is resolved to the game's title.
- Added "--clear-cache-on-room-change" command-line arg (and similar config option).
- Don't error when DrawingSurface.DrawImage has bad transparency parameter (warning instead).
- Don't error when detecting bad format in File.Read* functions (warning instead).
- Added stubs for agsshell plugin (a contemporary cross-platform variant of ags_shell).
- Added stubs for agsappopenurl plugin.
- Fixed potential crashes if a room-related API function has been called in "game_start"; this is achieved by having a dummy room placeholder object. Still results of such calls are undefined and should not be relied upon.
- Fixed potential crash on room load if the walkable area mask contained color values above the supported range.
- Fixed dialog script's "goto-previous" command not working if used from the first sub-topic run using "goto-dialog" (a very-very old bug).
- Fixed AGS_EngineInitGfx plugin callback was not called during OpenGL renderer initialization.
- Fixed Direct3D/OpenGL renderers were displaying plugin's raw drawings in a wrong position in the scrolling rooms, if the drawing was done on AGSE_PRESCREENDRAW or AGSE_POSTROOMDRAW events.
- Fixed overlay may fail to be created sometimes, if previously another overlay had been forcefully removed when changing rooms (this is an ancient bug which existed for many years).
- Fixed ListBox.RowCount reporting 0 if called before the control was displayed once.
- Fixed GetTextWidth would still return a size of an outline for an empty text string.
- Fixed text may be misaligned in gui controls, as its outline thickness is not counted.
- Fixed some TTF fonts could be cut at the bottom when the speech is displayed.
- Fixed scheduled sound fadeout effect was not cancelled by skipping a cutscene.
- Fixed OGV Theora videos positioned incorrectly if they have certain sizes or aspect ratios.
- Fixed game fps sped up if SetGameSpeed() is called repeatedly in game script.
- Fixed game not reacting to system close commands when stuck in script, which made it impossible
  to close the "hanging" game by usual means (other than terminating the process).

Engine Plugin API:
- Added IAGSEngine::GetGameInfo() function which returns information about the game, such as its title and GUID.
- Added new render callback AGSE_POSTROOMDRAW, for handling drawing inside the room above all room objects.
- Added IAGSFontRenderer2 interface, expanding the original font renderer interface, improving font plugins support.
- Added ReplaceFontRenderer2() and NotifyFontUpdated() functions.

Compatibility:
- Fallback to the first loop with frames if current character's loop does not have any.
- Use the dummy frame if current character's speech view loop does not have any.
- Ignore character having view/loop with no frames while it's not in the current room.
- Legacy behavior of MoveCharacterBlocking's return value.
- Fixed walkable area's continuous scaling was broken for high-res rooms in old games.
- In pre-3.* games force player to walkable area after changing rooms, this is to emulate an unintentional effect created by the old engines.
- Fixed pre-3.4.1 anti-aliased TTF fonts display (their vertical position was broken).
- For pre-3.5.0 games support old behavior of coincidental dynamic sprite replacement on GUI backgrounds (and few other places) without explicit assignment; that is - when the new DynamicSprite is created right after deleting an old one.
- Support Label.TextAlignment with legacy alignment constants for pre-3.5.0 games made with the custom engine from "Clifftop Games".
- Support native resolution hack for games made with "Clifftop Games" custom engine, where 640x400 games are run as 640x360.

Android:
- Rewrote universal AGS game launcher/player using up-to-date Google guidelines. The former "launcher" is now called "AGS Player".
- Implemented single game project template meant for building your own signed APK.
- Implemented two touch-to-mouse control scheme (selectable in config), for one finger emulating LMB only, and for two fingers emulating LMB and RMB.
- Support relative motion speed setting for touch-to-mouse emulation.
- In AGS Player added "Browse" button to the game folder selection, which opens default system file picker.
- AGS Player now searches for games recursively, in all the subfolders.
- AGS Player now has preference button per each game, which opens individual game's settings.

OSX:
- OpenGL renderer is now supported on MacOS.

Web / Emscripten:
- Initial port release.

Windows:
- Installer will create program links with three-digit version in the name.

Plugins:
- Added SpriteFont plugin to the list of builtins, for ports that use ones.
  SpriteFont plugin is updated to support custom "Clifftop Games" font variants.

WinSetup:
- Added "Fullscreen as borderless window" checkbox.
- Remade sound options to reflect the move to the new audio system in the engine.




Known issues

* Although Unicode text is supported overall, some languages may still not be printed correctly automatically. Firstly, those that require "letter linking", such as Arabic or Persian, do not have the proper linking on its own. This may be worked around using special text converters and fonts. Another issue is that texts printed right-to-left in the source (where print direction is done using Unicode's control characters) are not wrapped correctly and may require manual placement of line breaks, or scripting their split in game.
* MIDI no longer plays on its own on Windows. For MIDI you (and your players) must install "sound banks" (also known as "sound font"). Please refer to this article: https://adventuregamestudio.github.io/ags-manual/MIDI-playback.html
* AudioChannel.Position and AudioChannel.Seek do not work for MIDI and MOD sounds. Try sticking to PositionMs and SeekMs for now.
* There are reports about Direct3D not being able to restore the fullscreen mode after alt+tabbing occasionaly.

Summary

AGS 3.6.0 is another big change to AGS.
First of all, this release presents a SDL2-based engine. For about 2 decades AGS engine was based on Allegro 4 graphic library, which was discontinued somewhere in the early 2010-ies (only received few patches since). There was an intent to move to to Allegro 5 or SDL since, but for various reasons this task was continuously postponed. Now it's done.
Secondly the Editor and Engine now have full Unicode support. This means that you may use any language whatsoever in scripts, object descriptions and custom properties, as well as translations; so long as you also provide proper unicode fonts.
Third, we have finally expanded a list of platforms that the Editor can build for: now this includes Android and Web (Emscripten) port.

There are much more changes and improvements in this release, check out the full list of changes below.
Also, please be sure to read "Upgrading to AGS 3.6" topic in the manual: https://adventuregamestudio.github.io/ags-manual/UpgradeTo36.html



Changes in the Patch 2:

Common:
 - Fixed a TTF font could cause a crash in the Editor or the Engine if the font renderer tries to draw a letter with higher number than the highest glyph number in the font.

Editor:
 - Added "Restore all sprites..." command to the Sprite Manager's context menu (this duplicates the "File -> Recreate sprite file" menu command added previously).
 - Refresh Sprite Manager after fully recreating a sprite file.
 - Sprites will now hide their "Resolution" property if the game settings have "Allow relative asset resolutions" disabled. This is to avoid user's misuse of this property.
 - Fixed a minor memory leak occuring when editing a tree item's label in Project Explorer.

Engine:
 - Engine will now find and load plugins in the game dir when run from a different location.
 - Fixed crash occuring if Character was told to FaceLocation while "Turn to face" game setting is enabled, and character's View does not have enough loops.
 - Fixed Character resetting current non-blocking animation if it was ordered to Move, as soon as it arrives at destination.
 - Fixed crash occuring if a GUI button was somehow set a negative NormalImage number.
 - Fixed "bad script stack" error could be sometimes displayed if the game was aborted in the middle of running a script.



Changes in the Patch 1:

Editor:
 - Fixed room's deprecated setting LegacyMusicVolumeAdjustment not applied correctly.

Engine:
 - Fixed Room Objects whose dynamic sprite was deleted in "leave room" event becoming invisible during fade-out transition. Logically this has to happen, but historically they kept displaying until the transition end, so we restored this behavior for compatibility, and simply because there's no "after fade-out" event in the engine yet to delete these sprites.
 - Fixed Game.StopAudio() fails to remove queued clips if no particular audio type id is requested.
 - Fixed performance regression in the script related to long loops (regression in 3.6.0).
 - Fixed memory leak occuring when printing text in Right-to-left mode (regression in 3.6.0).
 - Fixed rare mistake during text wrapping which may occur if a Unicode text is cut in the middle of the word.
 - Fixed playing certain WAVs caused game to freeze forever on exit.

Compatibility:
 - Fixed frame-linked sounds not playing in the games made before 3.6.0.
 - Allow game to call DynamicSprite.Create() with negative size, clamping it to 1x1.

Templates:
 - In Sierra-style template fixed "mouse over" graphic for the "Load" icon.



What is new in 3.6.0

Common features:
 - Full Unicode support for all game texts: game properties, scripts, translations, input.
   ASCII/ANSI mode is still working, for backwards compatibility. This may be configured in the game project.
 - Extended sprite compression options: lossless storage optimization for 16- and 32-bit sprites; LZW compression option for sprites in addition to existing RLE compression.
 - GUI controls may now be told to clip their contents, which means that nothing gets drawn outside of their borders (as defined by X, Y, Width, Height properties). The only exception is Sliders, which are more complicated.
 - The historical TTF fonts' "fixup" that altered their height and vertical offset is now optional and works only if backwards compatible option is set.
 - Max number of AudioChannels is now 16 (was 8).
 - Removed game Cursors hard limit (was 20).
 - Increased Room Objects limit to 256 (was 40).
 - Discontinued "Windows Game Explorer" support in both Editor and Engine.

Editor:
 - Editor requires .NET Framework 4.6 to run.
 - Added Android build target support (requires "Android component" installed).
 - Added Web/Emscripten build target support (requires "Web build component" installed).
 - Expanded UI color theme format, support global color options and allow missing entries.
 - Script editor works in unicode mode.
 - Added "Text format" option in General Settings which lets switching between ASCII/ANSI and Unicode (UTF-8) modes. This defines which format the game texts will be written in, when saving the game project and compiling the game.
 - Added "Use old-style keyboard handling" option to the General Settings, which lets select between classic key press handling and new one meant for unicode chars support in scripts.
 - Supports compiling UTF-8 translations. TRS file now has "Encoding" setting that tells how to interpret this TRS text.
 - Added support for building multiple speech voxes, by taking files from the Speech subfolders.
 - Added support for adding custom files into the game package. This is done by assigning a list of directories to "Package custom data folder" option in General Settings.
 - Editor now copies a acsetup.cfg file from the project's root folder (if one is provided by) as a base for generating default config file. Settings from Default Setup will be written over, but other found options won't be removed.
 - Added "Sprite file compression" option in General Settings, replacing "Compress the sprite file" option. The new option allows a selection of compression algorithm used for sprites.
   Currently supported: None, RLE (old default compression) and LZW.
 - Added "Enable sprite storage optimization" option to the General Settings, that permits the editor to repack sprites in a different storage format, reducing their disk size whenever possible. This option may be used alongside with the sprite compression. Note that this does not change how the sprites work in game.
 - Added "GUI controls clip their contents" option to the General Settings.
 - Added "TTF fonts height used in the game logic" option to the General Settings, that makes your game use real font's pixel height when arranging text and text-based UI elements, as opposed to the nominal font's size.
 - Added "Touch to Mouse Emulation", "Touch to Mouse motion mode" and "Display FPS on Screen" to Default Setup. Removed few deprecated options.
 - Added "TTF font adjustment" property to Fonts, as well as to General Settings where it serves as a project default for the new fonts. This property lets you choose between "no changes" and backward compatible TTF fixup meant to keep fonts made for AGS displayed as they were meant to.
 - In the "Import TTF" dialog added a choice to import the size closest to the given pixel height.
 - Fonts now have Auto Outline Style and Auto Outline Thickness properties.
 - Fonts now have a readonly Family Name field, that lets user see the original name of a font they've imported (if available).
 - Added IdleDelay property to Characters that lets you set time needed to pass before IdleView is activated. This is equivalent to the Character.SetIdleView script function.
 - Added Character.IdleAnimationDelay property to let setup idle view's animation speed.
 - Added Cursor.AnimationDelay property to let setup cursor's animation speed.
 - The TextWindow edges now have distinct names in the dropdown list of the property grid.
 - Rooms created from a Blank template will now have default background of a game's resolution.
 - When creating new room objects they will now have their script names set to some default value.
 - Added Room.BackgroundAnimationEnabled property to let have disabled animation on room load.
 - Editor will now create an empty sprite file if one is missing in the game project. Any existing sprite descriptions in the project will be kept, letting user to reimport these from sources.
 - Added "File -> Restore all sprites from sources" menu command.
 - Added "Apply" button on editor's Preferences dialog.
 - In Preferences replaced "Import Color Theme" with a "Open Theme Folder", as a temporary solution for managing theme files.
 - Select script editor's font in the editor's Preferences.
 - Added "Help" option to the editor pane's tab context menu.
 - Upgraded script editor to Scintilla 3.21.1 and ScintillaNET 3.6.3.
 - Cursor's position in script is now displayed on the status bar.
 - Dialog scripts now too can open help topics for keywords or script functions under cursor on F1.
 - Added zoom controls for the Sprite Manager, Character, Cursor, Inventory and View panes.
 - Sprites may now be imported by drag'n'drop into the Sprite manager.
 - In sprite manager's context menu added command "Create source files for all sprites with missing / external sources..."
 - In sprite manager's context menu added (restored) command "Replace sprite using previous files".
   Also made "previous file" remembered consistently whenever a sprite is imported or replaced.
 - In sprite manager's "export all" dialog added "skip if inside project's folder" option.
 - In sprite manager's "export all" dialog added "reset tile settings" option.
 - On the View pane the frames having set delay and linked sound will be now indicated with icons.
 - Editor no longer errors and fails when opening a game project with some script files missing.
 - Editor no longer errors on empty translations when compiling the game.
 - Editor now exports values of the string type Custom Properties to translations.
 - Editor no longer prevents exporting string arguments from Get/SetTextProperty calls to TRS file.
 - Editor now cleanups spritefile on game load, identifying any data not referenced by the project and marking it for deletion.
 - Fixed editor silently enabling all available Build Targets when upgrading a pre-3.4.0 project. This could be very inconvenient as there are several of them supported now.
 - Fixed open folders in the Project Tree were collapsing whenever you create a new subfolder or change an object's name in properties.
 - Fixed editor was not preventing from entering Character's and AudioClip's ScriptName too long for the engine to handle.
 - Fixed Image and View properties in various objects were allowing negative values.
 - Fixed some of the object previews (at least GUI) could crash if user entered a non-existing sprite's number as an Image property.
 - Fixed editor displaying unhandled exception if the script which user is trying to open was missing. Instead it will now open a blank script.
 - Fixed room editor was suggesting to save the modified room even if no changes were made.
 - Fixed a recently imported sprite could be displayed incorrectly scaled up in the room editor for high-resolution games, if the "Allow relative asset resolutions" was enabled in General Settings, and the sprite 0 had "Resolution" property set to "Low".
 - Fixed program crash occuring on sprite's import if failed to open a source file for any reason.
 - Fixed View animation preview stopping at frame 100 (if loop contains over 100 frames).
 - Fixed going to a "find all" result in dialog script did not highlight the found text, and sometimes did not scroll down to it.
 - Fixed "Goto Definition" not working for Enums and Defines (macros).
 - Fixed script autocomplete sometimes was not updated right after opening a script.
 - Fixed script autocomplete for function calls was mistreating commas in strings and inline comments as if they were separating actual parameters.
 - Fixed script autocomplete was not displaying members of extended structs if the parent struct was declared in another header.
 - Fixed script autocomplete was not working for enum names.
 - Fixed structs and enums were not highlighted if declared inside a script's body.
 - Fixed in dialogs numbers inside names were incorrectly highlighted as numeric values.
 - Fixed matching or mismatching braces were not highlighted consistently at all times in regular and dialog scripts.
 - Fixed crash occuring when user was trying to set breakpoint on the very last line in script.
 - Fixed few editor panes were not opening correct help topics in F1.
 - (Possibly) fixed error message text in the runtime error popup could be drawn partially beyond the popup borders if the user's system has text scaling option enabled.

Compiler:
 - Support unicode character literals.
 - Support using float literals when defining default values for function arguments.
 - Support hexadecimal number literals (e.g. "0xABCDEF").
 - Removed 500-characters line limit.

Script API:
 - Expanded `on_key_press` callback, now supports two parameters: key code and key modifier flags.
 - In the new key handling mode `on_key_press` is called for each actual key press;
   e.g. combinations like Ctrl+Z will result in two `on_key_press` calls, one with eKeyCtrlLeft and second with eKeyZ; added support for "NEW_KEYINPUT_API" macro in scripts.
 - Implemented new `on_text_input(int ch)` callback which is called when the engine receives a printable character. This callback is essential for handling unicode chars in script.
 - Similarily, expanded `dialog_options_key_press` with the third `mod` argument, and implemented `dialog_options_text_input` callback for receiving unicode chars during the custom dialog options state.
 - Implemented `dialog_options_close` callback which is called when custom dialog options are removed from the screen. This allows to perform any required cleanup.
 - Added eEventEnterRoomAfterFadein event for `on_event` callback, which corresponds to "enter after fade-in" room event.
 - Added eKey constants for Shift, Control and Alt keys.
 - Added eKeyMod enum for key modifiers constants.
 - String.AppendChar(), ReplaceChar() functions and String.Chars[] property are now working with the unicode characters.
 - String.Format("%c") specifier will now be able to print unicode characters.
 - Extended Button.Animate() to have blocking style, direction and starting frame parameters, thus matching other Animate commands (of Character and Object).
 - Extended all Animate() commands by adding "volume" parameter, that defines volume of the frame-linked sounds for the duration of this animation.
 - Added Character.AnimationVolume, defining volume of the frame-linked sounds.
 - Added Character.IdleAnimationDelay to let control idle view's animation speed.
 - Character.Scaling is no longer limited by a range of 5-200 (now supports 1-32767).
 - Hotspot.Name and Object.Name may now be set in script.
 - Added Object.ManualScaling and Object.Scaling.
 - Deprecated Object.IgnoreScaling (use Object.ManualScaling instead).
 - Object.SetView default loop & frame values are now 0 (was -1 which retained loop and frame indexes from the previous view, often unexpected to the user).
 - DrawingSurface.DrawImage() and DrawSurface() now support optional source rect coordinates.
 - Added functions for getting DrawingSurface of room masks: GetDrawingSurfaceForWalkableArea(), GetDrawingSurfaceForWalkbehind(), Hotspot.GetDrawingSurface(), Region.GetDrawingSurface().
 - Added new delay parameter to Mouse.ChangeModeView() to let control cursor's animation speed.
 - Added Game.ChangeSpeechVox() and Game.SpeechVoxFilename, support switching the voice-over pack.
 - Added Mouse.AutoLock property that toggles automatic mouse lock inside the game window.
 - Added Room.Exists().
 - Added System.Log().
 - Added SkipWait() that skips any active Wait() function.
 - Added WaitMouse() to complement existing Wait functions.
 - Added InputType enum which defines input devices and lets create their sets as flags.
 - Added WaitInput(), a more generic and extendable function that accepts a combination of flags telling which input types to wait for.
 - All Wait* functions now may have infinite timeout if you pass a negative timeout parameter.
 - All Wait* functions now return the reason they were skipped: a combination of InputType flag and a respective key or button code.
 - Added GUIControl.Transparency property.
 - Added Overlay.CreateRoomGraphical and CreateRoomTextual. Use these two functions to create "room overlays": that is - overlays that display a sprite inside the room, sorted among other room objects, characters and walk-behinds.
 - Added readonly Overlay.InRoom property that tells if this is a room or screen overlay.
 - Extended Overlay.CreateGraphical() with a new "clone" parameter that tells whether to assign a sprite index, or make a sprite's copy owned exclusively by this overlay. The former will save program memory but make overlay update if the sprite is edited later. The latter is meant primarily for backwards compatibility.
   Overlay.CreateRoomGraphical has the same param.
 - Added Overlay.Graphic property that lets you change overlay's sprite after it's created.
 - Added Overlay.Width and Height properties, that let you freely scale existing Overlay.
 - Added readonly Overlay.GraphicWidth and GraphicHeight properties that let read original overlay's graphic size, as not all overlays hold a sprite reference (e.g. textual overlays).
 - Added Overlay.Transparency property.
 - Added Overlay.ZOrder property that lets you sort Overlays among themselves and other objects in the same "game layer": screen overlays are sorted among GUI, while room overlays are sorted among room objects, characters and walk-behinds.
 - Added Speech.TextOverlay and Speech.PortraitOverlay for accessing blocking speech overlay and portrait overlay respectively.
 - Added Game.BlockingWaitSkipped which tells the result of the last blocking wait skipping, also including result of the blocking speech skipping.
 - SkipSpeechStyle now supports eSkipNone mode; when used it will disable any kind of skipping, such speech can be only skipped by a direct command from script.
 - Extended Screen.ScreenToRoomPoint() with an optional "restrictToViewport" argument, which lets to choose whether tests over empty place result in conversion through the default viewport or a null pointer.
 - Added AudioClip.PlayOnChannel().
 - Added AudioChannel.Pause() and Resume() functions, and IsPaused property.
 - Added AudioChannel.SeekMs(), complementing PositionMs (as the Seek() function interprets position differently depending on the audio format).
 - PlayVideo() now supports an option to play both game's and video's audio track simultaneously.
 - Added File.WriteRawInt() to complement ReadRawInt().
 - File paths in script now support $DATA$ token, which tells to read files from the game package. This only works for read operations. Functions that support this token currently are:
   File.Open(), DynamicSprite.CreateFromFile(), ListBox.FillDirList().
 - Debug(2, 0) command that displayed walkable areas is superceded by Debug(2, n), where "n" is a mask type: 0 - none, 1 - hotspots, 2 - walkbehinds, 3 - walkable areas, 4 - regions. This command also works as a toggle switch, calling it with the same mask index will turn it off.
 - Debug(5, n) command that displayed character's walk paths now also works as a toggle switch.

Engine:
 - New SDL2-based backend for graphics, audio and input.
 - Hqx graphic filters discontinued (could be temporary).
 - Windows-only DirectMedia video playback discontinued (could be temporary).
   Only OGG/OGV videos are kept supported at this point.
 - Support resizing game window on desktop systems.
 - Support "borderless full-screen window" mode in addition to the real (exclusive) fullscreen.
 - Support for switching vertical sync at runtime with Direct3D/OpenGL renderers. Also enable vsync in windowed mode too.
 - Unicode (UTF-8) text support: engine can now switch between ASCII and UTF-8 text mode. This is controlled by both game's OPT_GAMETEXTENCODING setting and translation's "Encoding" setting: they tells whether to interpret game texts as UTF-8 or ASCII/ANSI.
 - Support optional translation's "GameEncoding" setting: it hints the original game's codepage to help with their conversion. This is mostly meant for translating existing older (ANSI) games.
 - Engine now supports using real pixel height of the TTF fonts when arranging text and UI elements on screen; using nominal import size of the font is used as a compatible mode for the old games.
 - Also supports separate "normal" and backward compatible "fixup" modes when initializing TTF fonts, letting to display both common TTFs and ones made specifically for AGS in the past to display as they were meant to be.
 - Supports scripts using functions and variables from any other scripts, regardless of the script module order in the project.
 - Removed limit of simultaneous Button animations.
 - Removed limit of Character followers.
 - Removed Overlay limit.
 - Character.SetWalkSpeed() is no longer restricted by an arbitrary limit of 50.
 - Process character's idle view based on real game speed, not hardcoded 40 fps.
 - Improved file writing times (e.g. when doing a game save) by using buffered file stream. Initial tests showed 50% faster file writing.
 - Engine now renders GUI controls as separate textures when using hardware accelerated renderers. This may significantly improve performance in the high-resolution games and games with large number of GUI elements on screen.
 - Engine now shares the video texture data for all game objects on screen sharing same sprite. This improves performance in case there are multiple objects which use same image.
 - Various performance optimizations for both raw drawing and texture updates (Direct3D/OpenGL).
 - Engine now ensures that in threaded audio mode the AudioChannel's state only changes once the game is updated, and not while the game script is running. This prevents situations when the clip could begin playing before all properties are set in script, or when AudioChannel's properties' values (such as Position) could change while running a game script.
 - 24-bit wav PCM support, comes with the new sound library.
 - File.ReadRawLineBack() now always reads full line, and not limited to 200 characters anymore.
 - Debug displays, such as showing room mask and character walk paths, are now implemented as non-blocking translucent overlays, allowing you to keep playing the game while they are on.
 - Implemented debug key controls for calling a built-in save and restore game dialogs. These controls have to be set in user config as "save_game_key" and "restore_game_key" in "[override]" category. These may be used by testers if the game is missing a save function or one is bugged.
 - Engine now supports loading compiled scripts as separate files packed along with the game, along with those embedded into the main game data or inside room files.
 - Engine no longer bails out with error if the chosen translation cannot be loaded on startup.
 - When reporting script errors, engine will print callstack for all the active script "threads": for example, if there's Wait() function called and error happened in repeatedly_execute_always, then it will print both actual error's location, and Wait() call's location.
 - Engine config now has graphic modes defined as a simplier string options: "[graphics] fullscreen" for the fullscreen mode setup, and "[graphics] window" for the windowed.
   Fullscreen option can explicitly define a "borderless full-screen window" mode.
 - Added "emul_mouse_mode" and "emul_mouse_relative" options to config in "[touch]" category.
 - Added "cache_size" and "stream_threshold" options to config in "[sound]" category, they setup the rules for sound caching and choosing whether to load a clip fully into mem or stream one.
 - Added "load_latest_save" and "show_fps" options to config in "[misc]" category.
 - Added "background" option to config in "[misc]" category, that defines the starting run-in-background (aka multitasking) mode (may later be changed by SetMultitaskingMode()).
   Added "--background" command line option for the same purpose.
 - Added "--sdl-log" command line option for setting up SDL2 library output verbosity. The engine log config now has a new "sdl" group meant for SDL2 messages.
 - Support "--user-conf-dir" command-line arg (and "user_conf_dir" config option) superceding "--localuserconf"; the new option directly tells the location of user config file.
 - Path related command-line and config options, - such as "shared_data_dir", "user_data_dir" and "user_conf_dir", now support $GAMENAME$ token in path which is resolved to the game's title.
 - Added "--clear-cache-on-room-change" command-line arg (and similar config option).
 - Don't error when DrawingSurface.DrawImage has bad transparency parameter (warning instead).
 - Don't error when detecting bad format in File.Read* functions (warning instead).
 - Added stubs for agsshell plugin (a contemporary cross-platform variant of ags_shell).
 - Added stubs for agsappopenurl plugin.
 - Fixed potential crashes if a room-related API function has been called in "game_start"; this is achieved by having a dummy room placeholder object. Still results of such calls are undefined and should not be relied upon.
 - Fixed potential crash on room load if the walkable area mask contained color values above the supported range.
 - Fixed dialog script's "goto-previous" command not working if used from the first sub-topic run using "goto-dialog" (a very-very old bug).
 - Fixed AGS_EngineInitGfx plugin callback was not called during OpenGL renderer initialization.
 - Fixed Direct3D/OpenGL renderers were displaying plugin's raw drawings in a wrong position in the scrolling rooms, if the drawing was done on AGSE_PRESCREENDRAW or AGSE_POSTROOMDRAW events.
 - Fixed overlay may fail to be created sometimes, if previously another overlay had been forcefully removed when changing rooms (this is an ancient bug which existed for many years).
 - Fixed ListBox.RowCount reporting 0 if called before the control was displayed once.
 - Fixed GetTextWidth would still return a size of an outline for an empty text string.
 - Fixed text may be misaligned in gui controls, as its outline thickness is not counted.
 - Fixed some TTF fonts could be cut at the bottom when the speech is displayed.
 - Fixed scheduled sound fadeout effect was not cancelled by skipping a cutscene.
 - Fixed OGV Theora videos positioned incorrectly if they have certain sizes or aspect ratios.
 - Fixed game fps sped up if SetGameSpeed() is called repeatedly in game script.
 - Fixed game not reacting to system close commands when stuck in script, which made it impossible
   to close the "hanging" game by usual means (other than terminating the process).

Engine Plugin API:
 - Added IAGSEngine::GetGameInfo() function which returns information about the game, such as its title and GUID.
 - Added new render callback AGSE_POSTROOMDRAW, for handling drawing inside the room above all room objects.
 - Added IAGSFontRenderer2 interface, expanding the original font renderer interface, improving font plugins support.
 - Added ReplaceFontRenderer2() and NotifyFontUpdated() functions.

Compatibility:
 - Fallback to the first loop with frames if current character's loop does not have any.
 - Use the dummy frame if current character's speech view loop does not have any.
 - Ignore character having view/loop with no frames while it's not in the current room.
 - Legacy behavior of MoveCharacterBlocking's return value.
 - Fixed walkable area's continuous scaling was broken for high-res rooms in old games.
 - In pre-3.* games force player to walkable area after changing rooms, this is to emulate an unintentional effect created by the old engines.
 - Fixed pre-3.4.1 anti-aliased TTF fonts display (their vertical position was broken).
 - For pre-3.5.0 games support old behavior of coincidental dynamic sprite replacement on GUI backgrounds (and few other places) without explicit assignment; that is - when the new DynamicSprite is created right after deleting an old one.
 - Support Label.TextAlignment with legacy alignment constants for pre-3.5.0 games made with the custom engine from "Clifftop Games".
 - Support native resolution hack for games made with "Clifftop Games" custom engine, where 640x400 games are run as 640x360.

Android:
 - Rewrote universal AGS game launcher/player using up-to-date Google guidelines. The former "launcher" is now called "AGS Player".
 - Implemented single game project template meant for building your own signed APK.
 - Implemented two touch-to-mouse control scheme (selectable in config), for one finger emulating LMB only, and for two fingers emulating LMB and RMB.
 - Support relative motion speed setting for touch-to-mouse emulation.
 - In AGS Player added "Browse" button to the game folder selection, which opens default system file picker.
 - AGS Player now searches for games recursively, in all the subfolders.
 - AGS Player now has preference button per each game, which opens individual game's settings.

OSX:
 - OpenGL renderer is now supported on MacOS.

Web / Emscripten:
 - Initial port release.

Windows:
 - Installer will create program links with three-digit version in the name.
 
Plugins:
 - Added SpriteFont plugin to the list of builtins, for ports that use ones.
   SpriteFont plugin is updated to support custom "Clifftop Games" font variants.

WinSetup:
 - Added "Fullscreen as borderless window" checkbox.
 - Remade sound options to reflect the move to the new audio system in the engine.




Known issues

* Although Unicode text is supported overall, some languages may still not be printed correctly automatically. Firstly, those that require "letter linking", such as Arabic or Persian, do not have the proper linking on its own. This may be worked around using special text converters and fonts. Another issue is that texts printed right-to-left in the source (where print direction is done using Unicode's control characters) are not wrapped correctly and may require manual placement of line breaks, or scripting their split in game.
* MIDI no longer plays on its own on Windows. For MIDI you (and your players) must install "sound banks" (also known as "sound font"). Please refer to this article: https://adventuregamestudio.github.io/ags-manual/MIDI-playback.html
* AudioChannel.Position and AudioChannel.Seek do not work for MIDI and MOD sounds. Try sticking to PositionMs and SeekMs for now.
* There are reports about Direct3D not being able to restore the fullscreen mode after alt+tabbing occasionaly.

Last updated: 16th June 2025



This release is brought to you by:

- Alan v.Drake
- Crimson Wizard
- edmundito (various fixes and improvements)
- eri0o (joystick & gamepad support, other improvements)
- fernewelten (new script compiler)
- ChamberOfFear, aka persn (open room format, Editor improvements)
- Matteo Piovanelli (improvements)
- KeyserSoSay0 (various fixes and improvements)



What is AGS 4

AGS 4.0 is an upcoming version which is currently in experimental stage. The primary idea of this version is a complete removal of the deprecated functionality: game settings and script functions. AGS 4 will no longer be able to run older 2.* or 3.* games. It will only guarantee the import of the latest 3.* game projects (such as 3.6.0). This means that if you want to update your existing game to AGS 4, then you'll have to first import and save it in 3.6.0. If your game is using any of the deprecated settings or script commands - you'll have to replace these, as 4.0 will no longer have necessary "backwards compatibility" switches in General Settings.

It is still in works, and there is a number of large changes planned.
But what are the ready major new features of AGS 4?

Open Room format

The new room format made by @ChamberOfFear now stores rooms as a collection of directories with room data split into multiple files. The room properties are stored in XML, which make it possible to read and even edit by hand outside of the editor. Room backgrounds and region masks are stored as separate PNG images.

This improves the safety of working with rooms, allows to change things externally, and simplify teamwork to some degree.

New script compiler with new syntax features

The new compiler was written by @fernewelten, and it grants a whole bunch of syntax improvements to the AGS script, such as nested structs, multi-dimensional arrays, dynamic arrays have `Length` pseudo-property, and so on.

The full cheat-sheet of the new features may be found here:
https://github.com/adventuregamestudio/ags/wiki/New-compiler%27s-end-user-cheat-sheet
If anyone is curious, here's the more "technical" version, explaining things in depth:
https://github.com/adventuregamestudio/ags/wiki/Features-of-the-new-Script-Compiler

Managed pointers inside managed structs

These are also allowed now (this is not related directly to the script compiler, but also to how engine handles dynamically created objects). This feature finally opens full potential of structs referencing each other with pointers, and allow you to create virtually any kind of data storage in script.

To give an example:
Code: ags
managed struct Item; // pre-declaration

managed struct Person {
    Item* items[];
};

managed struct Item {
    Person* owner;
};

Here's a LinkedList module I wrote for a test:
https://www.dropbox.com/s/sxur2bsccsvaqmr/ags399-LinkedList.zip?dl=0

Watch Variables panel

This panel lets you see values of the script variables while you run the game from the Editor.
An example of how it looks like is on this screenshot:
https://i.imgur.com/D1L69LH.png

Advanced object features

The game objects have two new features worth mentioning up front: Blend Mode and Rotation.
* BlendMode property lets you change the way object is drawn, selecting one of the 10 classic modes (Add, Subtract, Dodge, etc). This gives you ability to make more visual effects in your game.
* Rotation property (called GraphicRotation in some) lets you to rotate the object by a number of degrees. Most standard things have this, and even Cameras, so you may, for example, rotate the whole room view, and characters in it individually. Rotation is hardware accelerated (in Direct3D/OpenGL mode) and does not slow things down, unlike rotating dynamic sprites. Engine correctly detects clicks on rotated objects, so for example, rotated GUI will be fully functional.
* GUIs may be scaled using ScaleX and ScaleY properties (and SetScale function).

What else is PLANNED for AGS 4?

Here's the milestone proposal:
https://github.com/adventuregamestudio/ags/issues/1298

It's not clear at the moment whether all of these features will be a part of the first 4.0 release, but at least some of these will hopefully be.

How safe is this WIP version currently?

It is relatively stable, and there are few people who were already using it to make games for a while: Alan Drake is one of them, and I suspect that fernewelten was also using it sometimes for his games because of his new compiler (but I may be mistaken).
The biggest problem with this is that this version will be updated further, so some things may not be final. Project format may also change in the next updates. We'll try to keep things upgradeable (so that the previous projects made in this WIP version won't just break).
And it surely it will benefit from more testers.



The full changelog follows:

Contains all improvements and fixes from AGS 3.6.1 and 3.6.2 (including patches), except ones made for backwards compatibility.

Common:
 - Support true 32-bit colors in GUI, text messages and drawing commands in script.
   Color number properties now correspond to the encoded 32-bit ARGB (A8R8G8B8 format).
 - Fonts are split into Font Files and Fonts, where multiple Fonts may use same Font File, or not have any Font File assigned at all (for instance, if they are meant to act as placeholders and get replaced by fonts from plugin).
 - Most of the deprecated functionality (game settings and script API) is cut out from both Editor and Engine, and is no longer supported. The Editor guarantees to import the projects saved by AGS 3.6.0 and later, but *running* games compiled by pre-4.0 versions is no longer guaranteed.
 - Removed support for 16-bit games. Any older 16-bit project will be converted to 32-bit on import by the Editor.
 - Completely removed Global Messages and Room Messages.
 - Removed built-in support for Game Score, including related game settings and GiveScore script command. Users are advised to script their own score counter if they need one.
 - Removed support for '[' as a linebreak character in text.

Editor:
 - Editor requires .NET Framework 4.7 to run.
 - Open room project format: rooms are now saved as subfolders in "Rooms" folder, where each component has its own separate file (room data, backgrounds, masks and scripts).
 - "Fonts" node in the Project Explorer now contains separate "Font Files" and "Fonts" sublists.
 - Actual font files on disk are now stored in "Fonts" subfolder in the project when imported, and keep their original names (no longer renamed to "agsfntN.*").
 - Translation sources are now saved in PO format.
 - Merged all Color and ColorNumber property pairs into a single Color property that acts as a RGBA selection for 32-bit games, and palette index for 8-bit games. In 32-bit game projects you can assign full RGBA color definition, where alpha is optional, and is assumed 255 if not specified. Color value 0 means "transparent" regardless of game's color depth.
   NOTE: color picker currently does not let define alpha, so only opaque colors may be selected using it; but you may still enter RGBA value by hand.
 - In General Settings added "Script Compiler" option that lets to choose between old and new script compilers for your game (see "Scripting" section below for the new compiler's details).
 - In General Settings added "GUI common controls handle only left mouse button" option that lets prevent RMB from activating gui controls, except those that have separate actions for left and right mouse buttons.
 - Added Custom Properties for: Audio Clips, Dialogs, GUI, GUI Controls, Regions, Walkable Areas.
 - Added Enabled and Visible properties to Characters, Enabled property to Room Objects.
 - Added BlendMode property for Characters, GUI and Room Objects.
 - Added Transparency property for GUIControls.
 - Added Flip property for View Frame, replacing a boolean Flipped property. The new property supports all 3 flip variants: horizontal, vertical and both at once.
 - Added FaceDirectionRatio property to General Settings, Room and Walkable Areas.
 - Added readonly Length property to AudioClips, for the reference.
 - Added "Source FontFile" property to Fonts, this property lets assign a Font File to the Font.
 - Added XOffset and YOffset properties for the View Frames.
 - Redesigned Color Finder panel, now it lets to specify alpha color component, and convert between several different color representations.
 - Implemented "Watch Variables" panel which lets to watch values of the selected script variables while running the game. This feature is working only if game is built in Debug mode. The panel has an option to automatically enlist local variables (relative to current position in script).
 - Added "Add to Watch Panel" command to Script Editor's context menu.
 - Support dragging a text from the script window into the "Watch Variables" panel.
 - Added "Word Wrap" command to Edit menu for scripts.
 - General panel look enhancements.
 - Support built-in Base Color Themes that have the custom themes applied over them.
 - Support importing and keeping sprites as explicitly 8-bit images without converting to the game's default color depth. This lets to have chosen sprites used as 8-bit masks in a 16/32-bit game.
 - When importing room backgrounds of a different size Editor will now let user decide whether to reset, keep or rescale room masks.
 - Fixed faulty double-click on project items in case user dragged the cursor away.

Compiler:
 - The new extended script compiler is available. Almost all of the new Scripting features are only supported when using the new script compiler.
 - Optimization to the bytecode generation: same scripts may now work faster at runtime.

Scripting:
 - Managed structs may have constructors. Constructor is a member function which name is identical to the struct's name, and type is "void". Constructor will be called automatically when the managed object is created with "new" command.
 - Support for having regular structs inside any structs (regular or managed); there's no nesting limit.
 - Support having managed pointers inside managed structs.
 - When declaring a pointer to managed struct you may now omit "*" sign.
 - When writing struct's function's code you may now omit "this" keyword when addressing current struct's member (variable, attribute or function).
 - Similarly you may omit struct's name when addressing a static member from within a struct's member function.
 - Support for dynamic pointer cast: use syntax "pointer as Type" to cast the pointer to either a parent or child type (upcast and downcast respectively).
 - Extender attributes; similar to extender functions, but these define a pair of get_ and set_ functions.
 - Multi-dimensional regular arrays. They may have any positive number of dimensions.
 - Multi-dimensional dynamic arrays, also known as "jagged arrays". These are arrays of arrays, where each parent array's element has to be created separately, but may be of any independent length.
 - Regular arrays of dynamic arrays: that is a regular array where each element is a pointer to a dynamic array of the same type.
 - Dynamic arrays of regular structs.
 - Dynamic arrays now have Length pseudo-attribute used to retrieve their length.
 - Global variables may now be declared right after struct's or enum's declaration, between the closing bracket and closing semi-colon.
 - Support regular (non-managed) struct and array variable initializers, where you can specify their element values either in the order of their declaration or as a "name1: value, name2: value" sequence. For arrays the latter would be "0: value, 1: value" and so forth.
   NOTE: this works only for global variables at the moment.
 - Functions now may call any other function from within same script, regardless of their order of declaration.
 - When calling a function you may specify parameter names like "name1: value, name2: value", and when doing so - pass arguments in any order.
 - Compiler can now evaluate integer or float expressions at compile time whenever result is actually constant and can be calculated at compile time.
 - "const" keyword now may be used to define compile-time "int" and "float" constants.
 - "readonly" keyword now may be used to declare non-modifiable variables (local or global) and function parameters.
 - Added "fallthrough" keyword, which is used to hint that switch's case does not require a break statement. This is only to clarify coder's intent and prevent compiler's warnings.
 - Support pre-increment and pre-decrement operators (++x, --x).
 - Support bitwise negation operator (~x).
 - Support addressing members of the function return values in one expression. This lets chain multiple commands including function calls, e.g. GetObject().MyVariable...and so on.
 - Two sequenced string literals ("text" "text") are now automatically concatenated.
 - Dialog Scripts dropped support for a number of obsolete commands: "run-script", "new-room", "set-speech-view", "set-globalint", "play-sound", "add-inv", "lose-inv". All of those have contemporary equivalents.

Script API:
 - Most of the deprecated API is now removed completely, except those that have no equivalent.
 - Added SCRIPT_EXT_AGS4 macro which tells whether extended script syntax is supported by the compiler. This may be used to know whether the script is being compiled by the old or new compiler.
 - Added SCRIPT_EXT_NESTEDPOINTERS macro which tells whether nested managed structs are supported by the compiler.
 - All existing Color properties now assume full ARGB values (0xAARRGGBB) in 32-bit games. This means that you *must* specify alpha value when assigning a color number directly, otherwise the game will treat the color as fully transparent.
 - Added Joystick struct, meant to handle joystics and gamepads in script.
 - Added ShaderProgram and ShaderInstance structs, meant for the custom shaders support.
 - Added Touch and TouchPointer structs, meant to handle touch controls in script.
 - Added VideoPlayer struct, which provides means of playing non-blocking videos rendered onto a sprite that may be displayed on any game object.
 - Added WalkableArea and Walkbehind structs which let work with these region types in OO-style.
 - Added Pathfinder struct, which lets to search walkable paths in certain two-dimensional "space", and returns them as an array of Points.
 - Added MaskPathfinder struct, which lets to initialize a Pathfinder using a 8-bit sprite serving as a navigation mask.
 - Added MotionPath struct, which lets to read existing game object's motion plan, or create your own and use it as a reference when moving a custom object.
 - Added Custom Properties interface to types: AudioClip, Dialog, GUI, GUIControl, Region, WalkableArea. This includes functions: GetProperty(), GetTextProperty(), SetProperty() and SetTextProperty().
 - Added BlendMode enum.
 - Added Button.GraphicFlip property.
 - Added Character.BlendMode, GUI.BlendMode, GUIControl.BlendMode, Object.BlendMode, Overlay.BlendMode.
 - Added Character.Shader, GUI.Shader, GUIControl.Shader, Object.Shader, Overlay.Shader, Camera.Shader, Viewport.Shader, Mouse.CursorShader, Screen.Shader.
 - Added Character.Enabled and Visible properties, added Object.Enabled property, Character.on is deprecated.
 - Added Character.UseRegionTint and Object.UseRegionTint, deprecated Character.IgnoreLighting.
 - Added Camera.Rotation, Character.GraphicRotation, GUI.Rotation, GUIControl.Rotation, Object.GraphicRotation, Overlay.Rotation.
 - Added Game.GetColorFromRGBA() function that creates a color number for red, green, blue and alpha combination.
 - Added Game.FaceDirectionRatio, Room.FaceDirectionRatio, WalkableArea.FaceDirectionRatio and Character.FaceDirectionRatio.
 - Added Character.MovePath() and WalkPath() functions which makes character to move along an arbitrary list of coordinates.
 - Added Object.MovePath() function, that work similar to Character's.
 - Added Character.MotionPath and Object.MotionPath properties that let to get active character's or object's movement plan.
 - Added ColorFormat enum, and optional "color_format" parameter to DynamicSprite's functions: Create(), CreateFromBackground(), CreateFromDrawingSurface(), CreateFromExistingSprite() and CreateFromFile().
 - Added DialogOptionsNumbering enum, to use when setting dialog options numbering mode.
 - Added multiple new properties to Dialog type: OptionsBulletGraphic, OptionsGap, OptionsGUI, OptionsGUIX, OptionsGUIY, OptionsHighlightColor, OptionsMaxGUIWidth, OptionsMinGUIWidth, OptionsNumbering, OptionsPaddingX, OptionsPaddingY, OptionsReadColor, OptionTextAlignment.
   Most of these are replacing previously existing old-style variables in "game" struct and OPT_* options. OptionsGUIX/Y and OptionTextAlignment are completely new features.
 - Added DrawingSurface.BlendImage() and DrawingSurface.BlendSurface() functions.
 - Added DrawingSurface.BlendMode property that lets define blend mode for primitive drawing operations (line, rectangle, triangle, etc).
 - Added DrawingSurface.ColorDepth readonly property.
 - Added DrawingSurface.SetPixel() function that lets to set a pixel value of specified color, disregarding any surface's drawing settings.
 - Added Game.RoomCount, RoomNumbers[] and RoomNames[] properties.
 - Added Game.SpriteColorDepth[] readonly indexed property.
 - Added GUI.ScaleX and ScaleY properties, GUI.SetScale() function.
 - Added GUI.GUIToScreenPoint() and GUI.ScreenToGUIPoint() functions.
 - Added GUIControl.ScaleX and ScaleY properties, GUIControl.SetScale() function.
 - Added Math.Random(), Math.RandomFloat() and Math.Round() functions.
 - Added eRoundTowardsZero and eRoundAwayFromZero rounding styles for use in FloatToInt() and Math.Round() functions.
 - Added Overlay.Flip property that lets to set one of the 3 standard flip styles.
 - Added Overlay.Tint(), SetLightLevel() and RemoveTint() functions, Overlay.HasTint, HasLightLevel, LightLevel, TintBlue, TintGreen, TintRed, TintSaturation, TintLuminance properties, matching Character and Object tinting functionality.
 - Added Room.Number and Name properties.
 - Added Room.PathFinder property that returns a Pathfinder object, searching paths over this room's walkable areas.
 - Added StringSplitOptions enum, String.Join(), String.Split() and String.Trim() functions.
 - Expanded String.IndexOf() with new parameters: "StringCompareStyle", "index" and "count".
 - ViewFrame.Flipped property is now settable and returns eFlipDirection instead of bool.
 - ViewFrame.Speed property is now settable.
 - Added ViewFrame.XOffset and YOffset properties.
 - Added optional width, height and layer parameters to SaveScreenShot().
    SaveScreenShot() now supports location tokens in file path.
 - Added new game-wide option OPT_GUICONTROLMOUSEBUT that defines whether common GUI controls are affected by the right mouse button or not (InventoryWindows are excluded from this, because they have their own special handling for RMB).
 - Added "walkarea[]" and "walkbehind[]" global arrays.
 - Global generated game objects (Characters, GUIs, etc), and global arrays of these objects (character[], object[], gui[], etc) are now declared as object *pointers* and arrays of pointers respectively. From the user's perspective this is a mere formality, as working with these variables and arrays will be syntactically same, but this makes it easier for the engine to handle them and objects internally.
 - Removed "hasAlphaChannel" param from DynamicSprite.Create() and CreateFromExistingSprite().
 - Removed HasAlphaChannel property from DialogOptionsRenderingInfo.
 - Removed "transparent" param from Overlay.CreateGraphical() and CreateRoomGraphical().
 - Removed Object.MergeIntoBackground() function as redundant, and complicating Object's logic.

Engine:
 - Support joystick and gamepad input.
 - Support touch input directly, without touch-to-mouse emulation.
 - All color settings in a 32-bit game now respect alpha value, meaning they may be half-transparent. This refers to almost anything that may have a color: texts, GUI backgrounds, DrawingSurface's DrawingColor, and so forth. The exceptions are things that only make sense with opaque color: Tint settings, and screen Fade effects.
 - Support custom shaders, initialized through script API. Shaders are loaded and compiled from GLSL (for OpenGL) or HLSL (for Direct3D) shader scripts, and may be attached to game objects, camera, or the whole game view. Shaders may have user-defined constants, and have up to 3 secondary textures on input.
 - Support compressing game saves using Deflate algorithm. Added config option "compress_saves" in "misc" section, disabled by default.
 - Always compress a screenshot in game save using Deflate algorithm.
 - Implemented more accurate Character movement. The movement direction is now more precise and diagonal movement speed no longer may exceed MovementSpeed setting.
 - Camera will not follow a disabled player character.
 - Consistent GUI translation: the values of textual properties will never be automatically translated on assignment or reading them, only the text displayed on screen will be translated.
 - Animated buttons now display flipped frames correctly.
 - AudioChannel.Position and PositionMs no longer return a very large value while skipping cutscene.
 - Allow to run the game even if it has no fonts (log a warning).
 - Allow to continue running the game if any font failed to load on startup. Such font will simply not get drawn, unless replaced by a plugin, for example.
 - Standard Dialog options now support Right-to-left text mode.
 - Overlay.X and Y properties of textual screen overlays, such as blocking speech, now treat assigned values correctly as screen coordinates and return values set by user consistently. They also return the assigned values without any offsets for textual overlays created using a TextWindow (having extra borders and padding).
 - All the area-related GetAtScreenXY functions (for Hotspot, Region, Walkbehind and WalkableArea) now return a null pointer if no room viewport is found under given coordinates.
 - GetTextHeight() no longer reduces "width" parameter by -1. This was an ancient mistake in the engine kept for many years for backwards compatibility.
 - Both blocking and non-blocking videos are buffered and played on a separate thread.
 - Added FLAC support for music, speech and sound effects.
 - Added "--print-rtti" command line option which prints script RTTI table to the log.
   (RTTI stands for "runtime type information", and is used for handling of certain advanced script features, such as nested managed structs.)
 - Fixed SDL log level defaulting to "verbose" instead of "info".

Released: 28th December 2023

Previous stable version: AGS 3.6.0 P7 forum thread


This release is brought to you by:

- Alan v.Drake (fixes, improvements)
- Crimson Wizard
- edmundito (iOS fixes)
- eri0o
- Walter Agazzi (fixes)



What is new in 3.6.1

3.6.1 is planned to be a focused on improving performance and usability of existing features, and also possibly on restoring few functionalities cut while porting the engine to SDL2 (in 3.6.0).

Common features:
- Implemented Deflate compression option for sprites. (This is an algorithm used in PNG and ZIP formats, and testing shows about x1.5-x2 compression improvement compared to LZW).
- Removed length limits for: Game name, savegame folder, Character's script name and regular name (description), Inventory item's name (description), Mouse cursor's script name, Audioclip's script name.

Editor:
- Discontinued Source control integration functionality, removed "Put sound and sprite files in source control" option from General Settings.
- Made Editor a Dpi-aware application, which might improve its looks in Windows 10 and higher. This is disabled (may be temporarily), as it turned out to cause troubles on some user setups.
- Improved Room Editor controls:
  Added free panning mode done by holding the middle mouse button, or alternatively - by holding Space + LMB.
  Mouse Wheel without key modifiers scrolls the room vertically; Shift + Mouse Wheel scrolls
  the room horizontally.
  Zoom is done by Ctrl + Mouse Wheel and room now zooms towards or outwards the cursor position.
- In Room Editor the context menu is now displayed by RMB or Shift + RMB while editing masks.
  The individual room mode menu is merged with the "copy coordinates" command when shown.
- In Room Editor the hint with coordinates is now also displayed when moving Objects or Characters with keyboard.
- In Dialog Script editor support most Edit menu and context menu commands from the regular Script editor, with a few exceptions.
- In Sprite Manager added command "View" -> "Show filenames" which toggles display of a sprite's source filename under the sprites.
- During sprite export Editor will display a proper progress dialog.
- Zoom controls in Character and View panes now allow downscaling too. View editor displays the preview sprite stretched to fill the parent panel.
- View editor now allows to select multiple frames at once, across multiple loops too, using standard Shift + LMB and Ctrl + LMB combinations. Properties panel lets modify properties for all the selected frames at once.
- Added "Replace with all sprites from folder" command to the View editor's context menu.
- For Audio Clips in the project tree added "Force Reimport", "Force reimport all file(s)" and "Replace Source File" context menu commands.
- For Output Panel added "Copy selection" context menu command.
- Implemented Log Panel that lets you see the engine and game logs right in the Editor.
- Improved LipSync panel looks in case user's system has display scaling option enabled.
- "Goto Definition" command in script will now work for most of the game entities too, such as Characters, GUIs, and so forth. In that case it will find a game's entity and open a respective editor panel for it. This still does not work for some types, such as Room objects, and Views.
- Added main menu commands for opening a Project folder and Compiled folder.
- Added "Export Global Messages to script" menu command. This command is meant for upgraded pre-3.2 game projects, and will generate a script with a String array, moving global messages texts there.
- For script's tabs added a context menu command for opening this script's location.
- In General Settings moved few properties to different groups for better consistency.
- Added "Scale Character sprite offsets" property to General Settings. This property refers to scaling of Character.z and sprite offsets added by LockViewOffset script command.
- Added TextureCacheSize and SoundCacheSize properties to Default Setup. These let configure the sizes of runtime texture and sound cache sizes respectively.
- Added "Leave room after fade-out" event to Rooms (script function called "Unload" by default).
- Added Translated property to all GUI Controls (was available only in ListBox). Translated property tells whether this control's text has to be translated, and applied text direction (in right-to-left text mode).
- Support '\n' linebreak character in the Label's Text and potentially other text properties.
- When run with "/compile" argument Editor will print all messages to the console (stdout), instead of displaying modal message windows.
- For Android build target Editor now supports a directory to place plugins in.
- For Android build target disabled compression of .ags and .vox assets, as that seriously slows down engine streaming resources (sprites etc).
- When building a game for Android and Linux the Editor will now be more tolerant to missing plugins and only issue a warning instead of stopping with error.
- Config will now be saved in UTF-8, letting to support setup program's title text in unicode.
- For non-Windows build targets Editor will fix config containing Direct3D graphics driver option and set OpenGL instead.
- For Color Themes: implemented character literal, braces match and braces error settings.
- Made Editor be somewhat more tolerate to missing XML nodes in Game.agf, in many cases it will still let open a game.
- When upgrading older game projects, Editor will insert a call to SetRestartPoint() in the end of the 'game_start' function in GlobalScript.asc. This is done to complement removal of an automatic restart point in the engine. This inserted command is safe to remove.
- When upgrading pre-3.2 rooms with disabled SaveLoadEnabled property the Editor will reset this property and insert a comment with a warning into the corresponding room's script. This is done because this property is deprecated as is no longer accessible.
- Fixed Editor refusing to open a game if one of the translation files is missing.
- Fixed General Settings and Default Setup not working correctly right after importing a pre-3.* game project.
- Fixed importing GIFs or 8-bit PNGs may lose transparent pixels if source images used other palette index than 0 for transparency.
- Fixed sprites may get wrong transparency settings after "Crop sprite edges" operation.
- Fixed Project Explorer's folders collapsing after certain user actions, such as dragging items or renaming things.
- Fixed a rare exception when scrolling the room in the editor.
- Fixed deleting collapsed "region" in script would sometimes lead to portion of the script undeleted but staying invisible.
 - (Possibly) Fixed a "Index out of range" exception in Script editor, related to the "script location" drop-down list, which could occur at random circumstances while working with the script, and any Color Theme is enabled.
- Fixed Dialog properties displaying internal values not meant to be seen by a user.
- Fixed selecting parent GUI after its control did not display GUI's own properties in the Properties Grid.
- Fixed Editor could miss some of the files when cleaning up old compiled files after the Game's Filename property is changed.
- Fixed Editor generating deprecated settings in the default config file.

Scripting:
- Support "#else" preprocessor directive.

Script API:
- Implemented Room's "After fade-out" event.
- Added eEventLeaveRoomAfterFadeout event for the global "on_event".
- Added eEventGameSaved event which runs after game was saved.
- Expanded interaction functions for Character, Object, InventoryItem, Hotspot and Region types: now they all receive respective object's pointer as a parameter, similar to GUI event functions, as well as a cursor mode this interaction was run with, if applicable.
- Added Game.ResetDoOnceOnly(), which completely resets all DoOnceOnly instances.
- Added Game.PrecacheSprite() and Game.PrecacheView(), which preload certain sprites and linked frame sounds into the engine's cache memory.
- Added ScriptName property to AudioClip, Character, Dialog, GUI, GUIObject, Hotspot, InventoryItem, Object.
- Added static GetByName() function to AudioClip, Character, Dialog, GUI, GUIObject, Hotspot, InventoryItem, Object.
- Added Object.AnimationVolume property, which works similar to Character.AnimationVolume.
- Added static File.ResolvePath() and File.Path attribute.
- Added support for a text formatting to a number of functions: DisplayAtY(), Character.SayAt(), Character.SayBackground(), DrawingSurface.DrawStringWrapped().

Engine:
- Significant performance improvement to scripts. Script running speed restored to a level close to AGS 3.2.1. Testing few "script-heavy" games showed fps raise by up to 30-40% compared with 3.6.0 engine.
- Improved performance of String objects in script. For instance, appending a character to a String is now roughly x2 times faster, *sequential* iteration of String.Chars[] in Unicode mode is about x12 (!) times faster (Strings in ASCII mode have relatively less improvement, because they have been faster than Unicode mode already).
- Improved performance when creating, deleting and manipulating Overlays; allows the game to have thousands of those with much less slowing down.
- Improved performance when updating and deleting dynamic sprites, and notifying any objects that have to redraw themselves. Engine no longer resets Graphic properties of objects referencing deleted dynamic sprite to 0.
- Implemented "texture cache", in addition to the existing "sprite cache". The texture cache keeps textures generated from raw sprites and lets reusing them, improving performance and reducing CPU workload. The textures mostly occupy the video memory (on GPU). The actual impact is proportional to the game's resolution and amount of simultaneously animated objects on screen.
- WFN font renderer now supports unicode texts in utf-8.
- Buttons, ListBoxes and TextBoxes now support Right-to-left text direction.
- DrawingSurface.DrawString now supports Right-to-left text direction.
- All the script File functions now treat paths in case-insensitive way (including subdirs), which makes them platform-independent.
- Removed an automatic SetRestartPoint() call at startup. This is done in case user does not want to use default "restart" save slot, or has a custom save system.
- Support handling multiple mouse clicks per game frame, similar to how multiple key presses were supported since 3.6.0.
- When starting up, engine will now precache only first 4 or 8 loops of the starting player character's View. This is done to avoid filling sprite cache with too much sprites at once in case when the player's View contains lots of additional animations.
- Characters will now have their graphic offsets, set by Character.z property and LockViewOffset() function, scaled along with the character's own scaling. This is done so long as the respective game option is enabled in the General Settings.
- Ensure that character and object scaling is updated even when the game is not drawn. This fixes rare issues when their scale property did not update in time whilst the game was completely fadeout, and similar cases.
- Allow to change Character's move speed while its moving.
- When Character is ordered a new move command while already moving, the engine will try to make a smooth transition between old and new moving without a delay.
- Engine will now log a warning for the most incorrect parameters to Animate function instead of quitting the game.
- Engine will now skip blocking Character.Say commands instantly while skipping a cutscene.
- Added new config settings in "graphics" section: "sprite_cache_size" (which replaces deprecated "cachemax" in "misc") and "texture_cache_size".
- Character.AnimationVolume now applies to the portrait animation too.
- Object.SetView now lets invalid loop and frame values, and fallbacks to using loop 0, frame 0, printing a warning. This is also consistent with backwards-compatble SetObjectFrame() behavior.
- Changed Object.SetView() to not play a frame's sound, which could lead to a duplicated sound play if Object.Animate is run right after.
- Text Overlays internal images are now registered as dynamic sprites, and their IDs may be read from Overlay.Graphic. This lets find out their sizes using Game.SpriteWidth/SpriteHeight and optionally draw them somewhere using DrawingSurface.DrawImage().
- Ensure all the script API is now correctly available for the plugins.
- Engine will now safeguard plugin's reading and writing of game saves, so that any mistakes done by plugins won't affect other parts of a save.
- Engine will disable vsync in a "infinite fps" mode, because vsync prevents getting more fps.
- Engine will force any in-game debug messages to be displayed in standard message boxes, disregarding game's "Display all messages as speech" option.
- Print some info about memory usage when reporting a "Out of memory" error.
- Deprecated in-game "console", as practically useless.
- Added new config settings in "graphics" section: "sprite_cache_size" (which replaces deprecated "cachemax" in "misc") and "texture_cache_size".
- Fixed Characters may be seemingly "walking in place" for some time when arriving at destination.
- Fixed Display and Say commands treating the second met "&" sign as a voice-over token too (they must only check the first one in string).
- Fixed PlayMP3File() function limiting filename argument by an arbitrary number of characters.
- Fixed speechlines were adjusting their Y position while trying to not overlap GUIs even when these GUIs are completely offscreen.
- Fixed first Sierra-style speechline in a sequence was adjusting its Y position without need when GUIs are set to be hidden during game pause (this includes blocking speech). Normally, the speechlines are adjusting their Y position in order to not overlap GUIs, but when GUIs are hiding during speech there should not be any need to do so.
- Fixed GAMENAMElabel is not updated if Game.Name changes in script.
- Fixed script behavior in case a local variable was assigned a value without being initialized with a zero memory by compiler's instruction beforehand. This is not a problem with the standard compiler, but technically could be an issue with any custom implementation.

Engine Plugin API:
- Added IAGSStream interface, IAGSEngine.OpenFileStream() and GetFileStreamByHandle().
- Added IAGSEngine.ResolveFilePath() method, which resolves a script path (with location tokens) into a proper system filepath.
- Fixed IAGSEngine.GetFontType() incorrectly reporting TTF font type for WFN fonts with more than 128 characters.

Compatibility:
- In Editor, restored all the Character's variables available in "backward-compatible" mode. This is primarily to make it easier to import very old games.
- Fixed slower character walking speeds in pre-3.1 upscaled and high-resolution games.
- Fixed Object.SetView() and SetObjectFrame() not treating -1 for loop and frame as "keep previous values" in older games.
- Allow to run an animation over a loop with zero frames, by using the placeholder frame. This lets particular old games to continue running instead of crashing with error.
- Fixed inventory window not updated after game.top_inv_item is assigned a new value.
- Fixed a "New Room" command in old-style dialog scripts was preventing "First time Enter room" event to be called.

iOS:
- Updated port for 3.6.*.

Windows:
- Fixed a rare bug when the Windows engine could fail loading the game for no good reason. This error is related to a bug in Windows SDK 8.1.

Web / Emscripten:
- Fixed Safari cannot switch the game into fullscreen mode.

WinSetup:
- Added options for setting texture cache and sound cache size.





Log Panel

We're now featuring a new Editor window called "Log Panel".



If it's not present, it may be enabled in the "Window" menu.

This panel receives log messages from the engine when running the game in a test mode (F5), and prints in the text box. This is a short-term log, it's limited by 4k messages (i think) and when hitting the limit it will clear the older ones. Its main purpose is to let users see the current and the recent state of the game.

The log settings may be configured by pressing the "Show configuration" tool button, this will make them visible to the right from the log window. The settings include 2 groups of settings:
* Log Output - lets configure the minimal level of messages that the Editor will receive. These options are only applied once the game is starting.
* Log Filter - lets configure the current (temporary) level of messages. These options may be applied anytime.

The message types are dividing between Main, Game and Script.
Main - is the main engine messages, mostly related to something important initializing or changing.
Game - are various game-related events.
Script - are messages printed by a System.Log command in script.

The Log window's font may be configured separately, in Editor Preferences, on "Advanced" tab.

Expanded interaction functions

Regarding expanded interaction functions, these are functions connected to Look at, Interact, Talk to and other similar events. They all now may have 2 parameters: a pointer to object, and cursor mode, similar to the following examples:
Code: ags
function Ego_Interact(Character *c, CursorMode mode)
function oObject1_Look(Object *o, CursorMode mode)

Exceptions:
- Hotspot WalkOn and MouseOver events do not have CursorMode parameter.
- All Region events do not have CursorMode parameter.

The purpose of this addition is to improve situation where you connect same function to multiple events and/or multiple objects at once. In such case you will be able to distinguish object and mode for which the function is actually called.

These new parameters are optional. If you don't have them declared in script, they will be ignored by the engine, and your script is going to run as before.
Also, naturally, you do not have to use them, if you don't need to (even if they are declared).

WFN fonts supporting Unicode

Engine can now draw unicode texts using WFN fonts too, if WFN fonts have appropriate letters.
Unfortunately, existing WFN editors do not let add letters at indices higher than 255. This means they need to be upgraded to allow arbitrary higher slots.
Current WFN format does not exactly have a limit to the glyph index, but it has a limit to 64k bytes of letter pixel data. This amount potentially allows it to store several alphabets in low-resolution within a single font. You may always split languages into separate fonts anyway.

Here's the modified Radiant's FontEdit which supports editing any character in range 0-65535:
https://www.dropbox.com/s/xth28bfzu78vtqi/FontEditUni.zip?dl=0
this is an "unofficial" version made purely for test.
The source project may be found here (if anyone is interested):
https://github.com/ivan-mogilko/fontedit
The example of the WFN font hosting Greek alphabet (only capitals, for test):
https://github.com/adventuregamestudio/ags/files/11540578/AGSFNT0_UNI.zip
may be tried with e.g.
Code: ags
Display("ΟΙ ΘΕΟΙ ΤΟΥ ΟΛΥΜΠΟΥ"); // THE GODS OF OLYMPUS

Summary

AGS 3.6.0 is another big change to AGS.
First of all, this release presents a SDL2-based engine. For about 2 decades AGS engine was based on Allegro 4 graphic library, which was discontinued somewhere in the early 2010-ies (only received few patches since). There was an intent to move to to Allegro 5 or SDL since, but for various reasons this task was continuously postponed. Now it's done.
Secondly the Editor and Engine now have full Unicode support. This means that you may use any language whatsoever in scripts, object descriptions and custom properties, as well as translations; so long as you also provide proper unicode fonts.
Third, we have finally expanded a list of platforms that the Editor can build for: now this includes Android and Web (Emscripten) port.

There are much more changes and improvements in this release, check out the full list of changes below.
Also, please be sure to read "Upgrading to AGS 3.6" topic in the manual: https://adventuregamestudio.github.io/ags-manual/UpgradeTo36.html



Changes in the Patch 1:

Editor:
 - Fixed room's deprecated setting LegacyMusicVolumeAdjustment not applied correctly.

Engine:
 - Fixed Room Objects whose dynamic sprite was deleted in "leave room" event becoming invisible during fade-out transition. Logically this has to happen, but historically they kept displaying until the transition end, so we restored this behavior for compatibility, and simply because there's no "after fade-out" event in the engine yet to delete these sprites.
 - Fixed Game.StopAudio() fails to remove queued clips if no particular audio type id is requested.
 - Fixed performance regression in the script related to long loops (regression in 3.6.0).
 - Fixed memory leak occuring when printing text in Right-to-left mode (regression in 3.6.0).
 - Fixed rare mistake during text wrapping which may occur if a Unicode text is cut in the middle of the word.
 - Fixed playing certain WAVs caused game to freeze forever on exit.

Compatibility:
 - Fixed frame-linked sounds not playing in the games made before 3.6.0.
 - Allow game to call DynamicSprite.Create() with negative size, clamping it to 1x1.

Templates:
 - In Sierra-style template fixed "mouse over" graphic for the "Load" icon.



What is new in 3.6.0

Common features:
 - Full Unicode support for all game texts: game properties, scripts, translations, input.
   ASCII/ANSI mode is still working, for backwards compatibility. This may be configured in the game project.
 - Extended sprite compression options: lossless storage optimization for 16- and 32-bit sprites; LZW compression option for sprites in addition to existing RLE compression.
 - GUI controls may now be told to clip their contents, which means that nothing gets drawn outside of their borders (as defined by X, Y, Width, Height properties). The only exception is Sliders, which are more complicated.
 - The historical TTF fonts' "fixup" that altered their height and vertical offset is now optional and works only if backwards compatible option is set.
 - Max number of AudioChannels is now 16 (was 8).
 - Removed game Cursors hard limit (was 20).
 - Increased Room Objects limit to 256 (was 40).
 - Discontinued "Windows Game Explorer" support in both Editor and Engine.

Editor:
 - Editor requires .NET Framework 4.6 to run.
 - Added Android build target support (requires "Android component" installed).
 - Added Web/Emscripten build target support (requires "Web build component" installed).
 - Expanded UI color theme format, support global color options and allow missing entries.
 - Script editor works in unicode mode.
 - Added "Text format" option in General Settings which lets switching between ASCII/ANSI and Unicode (UTF-8) modes. This defines which format the game texts will be written in, when saving the game project and compiling the game.
 - Added "Use old-style keyboard handling" option to the General Settings, which lets select between classic key press handling and new one meant for unicode chars support in scripts.
 - Supports compiling UTF-8 translations. TRS file now has "Encoding" setting that tells how to interpret this TRS text.
 - Added support for building multiple speech voxes, by taking files from the Speech subfolders.
 - Added support for adding custom files into the game package. This is done by assigning a list of directories to "Package custom data folder" option in General Settings.
 - Editor now copies a acsetup.cfg file from the project's root folder (if one is provided by) as a base for generating default config file. Settings from Default Setup will be written over, but other found options won't be removed.
 - Added "Sprite file compression" option in General Settings, replacing "Compress the sprite file" option. The new option allows a selection of compression algorithm used for sprites.
   Currently supported: None, RLE (old default compression) and LZW.
 - Added "Enable sprite storage optimization" option to the General Settings, that permits the editor to repack sprites in a different storage format, reducing their disk size whenever possible. This option may be used alongside with the sprite compression. Note that this does not change how the sprites work in game.
 - Added "GUI controls clip their contents" option to the General Settings.
 - Added "TTF fonts height used in the game logic" option to the General Settings, that makes your game use real font's pixel height when arranging text and text-based UI elements, as opposed to the nominal font's size.
 - Added "Touch to Mouse Emulation", "Touch to Mouse motion mode" and "Display FPS on Screen" to Default Setup. Removed few deprecated options.
 - Added "TTF font adjustment" property to Fonts, as well as to General Settings where it serves as a project default for the new fonts. This property lets you choose between "no changes" and backward compatible TTF fixup meant to keep fonts made for AGS displayed as they were meant to.
 - In the "Import TTF" dialog added a choice to import the size closest to the given pixel height.
 - Fonts now have Auto Outline Style and Auto Outline Thickness properties.
 - Fonts now have a readonly Family Name field, that lets user see the original name of a font they've imported (if available).
 - Added IdleDelay property to Characters that lets you set time needed to pass before IdleView is activated. This is equivalent to the Character.SetIdleView script function.
 - Added Character.IdleAnimationDelay property to let setup idle view's animation speed.
 - Added Cursor.AnimationDelay property to let setup cursor's animation speed.
 - The TextWindow edges now have distinct names in the dropdown list of the property grid.
 - Rooms created from a Blank template will now have default background of a game's resolution.
 - When creating new room objects they will now have their script names set to some default value.
 - Added Room.BackgroundAnimationEnabled property to let have disabled animation on room load.
 - Editor will now create an empty sprite file if one is missing in the game project. Any existing sprite descriptions in the project will be kept, letting user to reimport these from sources.
 - Added "File -> Restore all sprites from sources" menu command.
 - Added "Apply" button on editor's Preferences dialog.
 - In Preferences replaced "Import Color Theme" with a "Open Theme Folder", as a temporary solution for managing theme files.
 - Select script editor's font in the editor's Preferences.
 - Added "Help" option to the editor pane's tab context menu.
 - Upgraded script editor to Scintilla 3.21.1 and ScintillaNET 3.6.3.
 - Cursor's position in script is now displayed on the status bar.
 - Dialog scripts now too can open help topics for keywords or script functions under cursor on F1.
 - Added zoom controls for the Sprite Manager, Character, Cursor, Inventory and View panes.
 - Sprites may now be imported by drag'n'drop into the Sprite manager.
 - In sprite manager's context menu added command "Create source files for all sprites with missing / external sources..."
 - In sprite manager's context menu added (restored) command "Replace sprite using previous files".
   Also made "previous file" remembered consistently whenever a sprite is imported or replaced.
 - In sprite manager's "export all" dialog added "skip if inside project's folder" option.
 - In sprite manager's "export all" dialog added "reset tile settings" option.
 - On the View pane the frames having set delay and linked sound will be now indicated with icons.
 - Editor no longer errors and fails when opening a game project with some script files missing.
 - Editor no longer errors on empty translations when compiling the game.
 - Editor now exports values of the string type Custom Properties to translations.
 - Editor no longer prevents exporting string arguments from Get/SetTextProperty calls to TRS file.
 - Editor now cleanups spritefile on game load, identifying any data not referenced by the project and marking it for deletion.
 - Fixed editor silently enabling all available Build Targets when upgrading a pre-3.4.0 project. This could be very inconvenient as there are several of them supported now.
 - Fixed open folders in the Project Tree were collapsing whenever you create a new subfolder or change an object's name in properties.
 - Fixed editor was not preventing from entering Character's and AudioClip's ScriptName too long for the engine to handle.
 - Fixed Image and View properties in various objects were allowing negative values.
 - Fixed some of the object previews (at least GUI) could crash if user entered a non-existing sprite's number as an Image property.
 - Fixed editor displaying unhandled exception if the script which user is trying to open was missing. Instead it will now open a blank script.
 - Fixed room editor was suggesting to save the modified room even if no changes were made.
 - Fixed a recently imported sprite could be displayed incorrectly scaled up in the room editor for high-resolution games, if the "Allow relative asset resolutions" was enabled in General Settings, and the sprite 0 had "Resolution" property set to "Low".
 - Fixed program crash occuring on sprite's import if failed to open a source file for any reason.
 - Fixed View animation preview stopping at frame 100 (if loop contains over 100 frames).
 - Fixed going to a "find all" result in dialog script did not highlight the found text, and sometimes did not scroll down to it.
 - Fixed "Goto Definition" not working for Enums and Defines (macros).
 - Fixed script autocomplete sometimes was not updated right after opening a script.
 - Fixed script autocomplete for function calls was mistreating commas in strings and inline comments as if they were separating actual parameters.
 - Fixed script autocomplete was not displaying members of extended structs if the parent struct was declared in another header.
 - Fixed script autocomplete was not working for enum names.
 - Fixed structs and enums were not highlighted if declared inside a script's body.
 - Fixed in dialogs numbers inside names were incorrectly highlighted as numeric values.
 - Fixed matching or mismatching braces were not highlighted consistently at all times in regular and dialog scripts.
 - Fixed crash occuring when user was trying to set breakpoint on the very last line in script.
 - Fixed few editor panes were not opening correct help topics in F1.
 - (Possibly) fixed error message text in the runtime error popup could be drawn partially beyond the popup borders if the user's system has text scaling option enabled.

Compiler:
 - Support unicode character literals.
 - Support using float literals when defining default values for function arguments.
 - Support hexadecimal number literals (e.g. "0xABCDEF").
 - Removed 500-characters line limit.

Script API:
 - Expanded `on_key_press` callback, now supports two parameters: key code and key modifier flags.
 - In the new key handling mode `on_key_press` is called for each actual key press;
   e.g. combinations like Ctrl+Z will result in two `on_key_press` calls, one with eKeyCtrlLeft and second with eKeyZ; added support for "NEW_KEYINPUT_API" macro in scripts.
 - Implemented new `on_text_input(int ch)` callback which is called when the engine receives a printable character. This callback is essential for handling unicode chars in script.
 - Similarily, expanded `dialog_options_key_press` with the third `mod` argument, and implemented `dialog_options_text_input` callback for receiving unicode chars during the custom dialog options state.
 - Implemented `dialog_options_close` callback which is called when custom dialog options are removed from the screen. This allows to perform any required cleanup.
 - Added eEventEnterRoomAfterFadein event for `on_event` callback, which corresponds to "enter after fade-in" room event.
 - Added eKey constants for Shift, Control and Alt keys.
 - Added eKeyMod enum for key modifiers constants.
 - String.AppendChar(), ReplaceChar() functions and String.Chars[] property are now working with the unicode characters.
 - String.Format("%c") specifier will now be able to print unicode characters.
 - Extended Button.Animate() to have blocking style, direction and starting frame parameters, thus matching other Animate commands (of Character and Object).
 - Extended all Animate() commands by adding "volume" parameter, that defines volume of the frame-linked sounds for the duration of this animation.
 - Added Character.AnimationVolume, defining volume of the frame-linked sounds.
 - Added Character.IdleAnimationDelay to let control idle view's animation speed.
 - Character.Scaling is no longer limited by a range of 5-200 (now supports 1-32767).
 - Hotspot.Name and Object.Name may now be set in script.
 - Added Object.ManualScaling and Object.Scaling.
 - Deprecated Object.IgnoreScaling (use Object.ManualScaling instead).
 - Object.SetView default loop & frame values are now 0 (was -1 which retained loop and frame indexes from the previous view, often unexpected to the user).
 - DrawingSurface.DrawImage() and DrawSurface() now support optional source rect coordinates.
 - Added functions for getting DrawingSurface of room masks: GetDrawingSurfaceForWalkableArea(), GetDrawingSurfaceForWalkbehind(), Hotspot.GetDrawingSurface(), Region.GetDrawingSurface().
 - Added new delay parameter to Mouse.ChangeModeView() to let control cursor's animation speed.
 - Added Game.ChangeSpeechVox() and Game.SpeechVoxFilename, support switching the voice-over pack.
 - Added Mouse.AutoLock property that toggles automatic mouse lock inside the game window.
 - Added Room.Exists().
 - Added System.Log().
 - Added SkipWait() that skips any active Wait() function.
 - Added WaitMouse() to complement existing Wait functions.
 - Added InputType enum which defines input devices and lets create their sets as flags.
 - Added WaitInput(), a more generic and extendable function that accepts a combination of flags telling which input types to wait for.
 - All Wait* functions now may have infinite timeout if you pass a negative timeout parameter.
 - All Wait* functions now return the reason they were skipped: a combination of InputType flag and a respective key or button code.
 - Added GUIControl.Transparency property.
 - Added Overlay.CreateRoomGraphical and CreateRoomTextual. Use these two functions to create "room overlays": that is - overlays that display a sprite inside the room, sorted among other room objects, characters and walk-behinds.
 - Added readonly Overlay.InRoom property that tells if this is a room or screen overlay.
 - Extended Overlay.CreateGraphical() with a new "clone" parameter that tells whether to assign a sprite index, or make a sprite's copy owned exclusively by this overlay. The former will save program memory but make overlay update if the sprite is edited later. The latter is meant primarily for backwards compatibility.
   Overlay.CreateRoomGraphical has the same param.
 - Added Overlay.Graphic property that lets you change overlay's sprite after it's created.
 - Added Overlay.Width and Height properties, that let you freely scale existing Overlay.
 - Added readonly Overlay.GraphicWidth and GraphicHeight properties that let read original overlay's graphic size, as not all overlays hold a sprite reference (e.g. textual overlays).
 - Added Overlay.Transparency property.
 - Added Overlay.ZOrder property that lets you sort Overlays among themselves and other objects in the same "game layer": screen overlays are sorted among GUI, while room overlays are sorted among room objects, characters and walk-behinds.
 - Added Speech.TextOverlay and Speech.PortraitOverlay for accessing blocking speech overlay and portrait overlay respectively.
 - Added Game.BlockingWaitSkipped which tells the result of the last blocking wait skipping, also including result of the blocking speech skipping.
 - SkipSpeechStyle now supports eSkipNone mode; when used it will disable any kind of skipping, such speech can be only skipped by a direct command from script.
 - Extended Screen.ScreenToRoomPoint() with an optional "restrictToViewport" argument, which lets to choose whether tests over empty place result in conversion through the default viewport or a null pointer.
 - Added AudioClip.PlayOnChannel().
 - Added AudioChannel.Pause() and Resume() functions, and IsPaused property.
 - Added AudioChannel.SeekMs(), complementing PositionMs (as the Seek() function interprets position differently depending on the audio format).
 - PlayVideo() now supports an option to play both game's and video's audio track simultaneously.
 - Added File.WriteRawInt() to complement ReadRawInt().
 - File paths in script now support $DATA$ token, which tells to read files from the game package. This only works for read operations. Functions that support this token currently are:
   File.Open(), DynamicSprite.CreateFromFile(), ListBox.FillDirList().
 - Debug(2, 0) command that displayed walkable areas is superceded by Debug(2, n), where "n" is a mask type: 0 - none, 1 - hotspots, 2 - walkbehinds, 3 - walkable areas, 4 - regions. This command also works as a toggle switch, calling it with the same mask index will turn it off.
 - Debug(5, n) command that displayed character's walk paths now also works as a toggle switch.

Engine:
 - New SDL2-based backend for graphics, audio and input.
 - Hqx graphic filters discontinued (could be temporary).
 - Windows-only DirectMedia video playback discontinued (could be temporary).
   Only OGG/OGV videos are kept supported at this point.
 - Support resizing game window on desktop systems.
 - Support "borderless full-screen window" mode in addition to the real (exclusive) fullscreen.
 - Support for switching vertical sync at runtime with Direct3D/OpenGL renderers. Also enable vsync in windowed mode too.
 - Unicode (UTF-8) text support: engine can now switch between ASCII and UTF-8 text mode. This is controlled by both game's OPT_GAMETEXTENCODING setting and translation's "Encoding" setting: they tells whether to interpret game texts as UTF-8 or ASCII/ANSI.
 - Support optional translation's "GameEncoding" setting: it hints the original game's codepage to help with their conversion. This is mostly meant for translating existing older (ANSI) games.
 - Engine now supports using real pixel height of the TTF fonts when arranging text and UI elements on screen; using nominal import size of the font is used as a compatible mode for the old games.
 - Also supports separate "normal" and backward compatible "fixup" modes when initializing TTF fonts, letting to display both common TTFs and ones made specifically for AGS in the past to display as they were meant to be.
 - Supports scripts using functions and variables from any other scripts, regardless of the script module order in the project.
 - Removed limit of simultaneous Button animations.
 - Removed limit of Character followers.
 - Removed Overlay limit.
 - Character.SetWalkSpeed() is no longer restricted by an arbitrary limit of 50.
 - Process character's idle view based on real game speed, not hardcoded 40 fps.
 - Improved file writing times (e.g. when doing a game save) by using buffered file stream. Initial tests showed 50% faster file writing.
 - Engine now renders GUI controls as separate textures when using hardware accelerated renderers. This may significantly improve performance in the high-resolution games and games with large number of GUI elements on screen.
 - Engine now shares the video texture data for all game objects on screen sharing same sprite. This improves performance in case there are multiple objects which use same image.
 - Various performance optimizations for both raw drawing and texture updates (Direct3D/OpenGL).
 - Engine now ensures that in threaded audio mode the AudioChannel's state only changes once the game is updated, and not while the game script is running. This prevents situations when the clip could begin playing before all properties are set in script, or when AudioChannel's properties' values (such as Position) could change while running a game script.
 - 24-bit wav PCM support, comes with the new sound library.
 - File.ReadRawLineBack() now always reads full line, and not limited to 200 characters anymore.
 - Debug displays, such as showing room mask and character walk paths, are now implemented as non-blocking translucent overlays, allowing you to keep playing the game while they are on.
 - Implemented debug key controls for calling a built-in save and restore game dialogs. These controls have to be set in user config as "save_game_key" and "restore_game_key" in "[override]" category. These may be used by testers if the game is missing a save function or one is bugged.
 - Engine now supports loading compiled scripts as separate files packed along with the game, along with those embedded into the main game data or inside room files.
 - Engine no longer bails out with error if the chosen translation cannot be loaded on startup.
 - When reporting script errors, engine will print callstack for all the active script "threads": for example, if there's Wait() function called and error happened in repeatedly_execute_always, then it will print both actual error's location, and Wait() call's location.
 - Engine config now has graphic modes defined as a simplier string options: "[graphics] fullscreen" for the fullscreen mode setup, and "[graphics] window" for the windowed.
   Fullscreen option can explicitly define a "borderless full-screen window" mode.
 - Added "emul_mouse_mode" and "emul_mouse_relative" options to config in "[touch]" category.
 - Added "cache_size" and "stream_threshold" options to config in "[sound]" category, they setup the rules for sound caching and choosing whether to load a clip fully into mem or stream one.
 - Added "load_latest_save" and "show_fps" options to config in "[misc]" category.
 - Added "background" option to config in "[misc]" category, that defines the starting run-in-background (aka multitasking) mode (may later be changed by SetMultitaskingMode()).
   Added "--background" command line option for the same purpose.
 - Added "--sdl-log" command line option for setting up SDL2 library output verbosity. The engine log config now has a new "sdl" group meant for SDL2 messages.
 - Support "--user-conf-dir" command-line arg (and "user_conf_dir" config option) superceding "--localuserconf"; the new option directly tells the location of user config file.
 - Path related command-line and config options, - such as "shared_data_dir", "user_data_dir" and "user_conf_dir", now support $GAMENAME$ token in path which is resolved to the game's title.
 - Added "--clear-cache-on-room-change" command-line arg (and similar config option).
 - Don't error when DrawingSurface.DrawImage has bad transparency parameter (warning instead).
 - Don't error when detecting bad format in File.Read* functions (warning instead).
 - Added stubs for agsshell plugin (a contemporary cross-platform variant of ags_shell).
 - Added stubs for agsappopenurl plugin.
 - Fixed potential crashes if a room-related API function has been called in "game_start"; this is achieved by having a dummy room placeholder object. Still results of such calls are undefined and should not be relied upon.
 - Fixed potential crash on room load if the walkable area mask contained color values above the supported range.
 - Fixed dialog script's "goto-previous" command not working if used from the first sub-topic run using "goto-dialog" (a very-very old bug).
 - Fixed AGS_EngineInitGfx plugin callback was not called during OpenGL renderer initialization.
 - Fixed Direct3D/OpenGL renderers were displaying plugin's raw drawings in a wrong position in the scrolling rooms, if the drawing was done on AGSE_PRESCREENDRAW or AGSE_POSTROOMDRAW events.
 - Fixed overlay may fail to be created sometimes, if previously another overlay had been forcefully removed when changing rooms (this is an ancient bug which existed for many years).
 - Fixed ListBox.RowCount reporting 0 if called before the control was displayed once.
 - Fixed GetTextWidth would still return a size of an outline for an empty text string.
 - Fixed text may be misaligned in gui controls, as its outline thickness is not counted.
 - Fixed some TTF fonts could be cut at the bottom when the speech is displayed.
 - Fixed scheduled sound fadeout effect was not cancelled by skipping a cutscene.
 - Fixed OGV Theora videos positioned incorrectly if they have certain sizes or aspect ratios.
 - Fixed game fps sped up if SetGameSpeed() is called repeatedly in game script.
 - Fixed game not reacting to system close commands when stuck in script, which made it impossible
   to close the "hanging" game by usual means (other than terminating the process).

Engine Plugin API:
 - Added IAGSEngine::GetGameInfo() function which returns information about the game, such as its title and GUID.
 - Added new render callback AGSE_POSTROOMDRAW, for handling drawing inside the room above all room objects.
 - Added IAGSFontRenderer2 interface, expanding the original font renderer interface, improving font plugins support.
 - Added ReplaceFontRenderer2() and NotifyFontUpdated() functions.

Compatibility:
 - Fallback to the first loop with frames if current character's loop does not have any.
 - Use the dummy frame if current character's speech view loop does not have any.
 - Ignore character having view/loop with no frames while it's not in the current room.
 - Legacy behavior of MoveCharacterBlocking's return value.
 - Fixed walkable area's continuous scaling was broken for high-res rooms in old games.
 - In pre-3.* games force player to walkable area after changing rooms, this is to emulate an unintentional effect created by the old engines.
 - Fixed pre-3.4.1 anti-aliased TTF fonts display (their vertical position was broken).
 - For pre-3.5.0 games support old behavior of coincidental dynamic sprite replacement on GUI backgrounds (and few other places) without explicit assignment; that is - when the new DynamicSprite is created right after deleting an old one.
 - Support Label.TextAlignment with legacy alignment constants for pre-3.5.0 games made with the custom engine from "Clifftop Games".
 - Support native resolution hack for games made with "Clifftop Games" custom engine, where 640x400 games are run as 640x360.

Android:
 - Rewrote universal AGS game launcher/player using up-to-date Google guidelines. The former "launcher" is now called "AGS Player".
 - Implemented single game project template meant for building your own signed APK.
 - Implemented two touch-to-mouse control scheme (selectable in config), for one finger emulating LMB only, and for two fingers emulating LMB and RMB.
 - Support relative motion speed setting for touch-to-mouse emulation.
 - In AGS Player added "Browse" button to the game folder selection, which opens default system file picker.
 - AGS Player now searches for games recursively, in all the subfolders.
 - AGS Player now has preference button per each game, which opens individual game's settings.

OSX:
 - OpenGL renderer is now supported on MacOS.

Web / Emscripten:
 - Initial port release.

Windows:
 - Installer will create program links with three-digit version in the name.
 
Plugins:
 - Added SpriteFont plugin to the list of builtins, for ports that use ones.
   SpriteFont plugin is updated to support custom "Clifftop Games" font variants.

WinSetup:
 - Added "Fullscreen as borderless window" checkbox.
 - Remade sound options to reflect the move to the new audio system in the engine.




Known issues

* Although Unicode text is supported overall, some languages may still not be printed correctly automatically. Firstly, those that require "letter linking", such as Arabic or Persian, do not have the proper linking on its own. This may be worked around using special text converters and fonts. Another issue is that texts printed right-to-left in the source (where print direction is done using Unicode's control characters) are not wrapped correctly and may require manual placement of line breaks, or scripting their split in game.
* MIDI no longer plays on its own on Windows. For MIDI you (and your players) must install "sound banks" (also known as "sound font"). Please refer to this article: https://adventuregamestudio.github.io/ags-manual/MIDI-playback.html
* AudioChannel.Position and AudioChannel.Seek do not work for MIDI and MOD sounds. Try sticking to PositionMs and SeekMs for now.
* There are reports about Direct3D not being able to restore the fullscreen mode after alt+tabbing occasionaly.





Thanks to everyone who contributed to and tested this version!

Hello, this is literally a AGS HELP WANTED, in the sense that we need help for the AGS itself.

The AGS manual is lacking many topics, and some existing ones are not complete or not very well done overall. Unfortunately, there have been very little volunteers to help with it over the years.

I cannot remember if I did this before on Recruitment board, but I decided to do now (again?).

We are looking for a person which is:
- Good with writing in English;
- Good with explaining things to people, especially to those who might have less technical knowledge about the topic;
- Good with AGS, of course (you must know the subject well).

Our manual (source) repository is here:
https://github.com/adventuregamestudio/ags-manual
The manual may be edited as a Wiki, using Markdown language:
https://github.com/adventuregamestudio/ags-manual/wiki
There are basic guidelines for working with it:
https://github.com/adventuregamestudio/ags-manual/blob/master/CONTRIBUTING.md
I think the Tutorial pages may be used as an example of a "tone" that we'd like to have, that is not overly encyclopedic, and easy enough to understand for a non-technical person or a kid:
https://github.com/adventuregamestudio/ags-manual/wiki/acintro1
https://github.com/adventuregamestudio/ags-manual/wiki/acintro2
https://github.com/adventuregamestudio/ags-manual/wiki/acintro3


Currently this may be edited by anyone who has a Github account, although the dev team retains a right to edit or even reset your changes if you do something weird there. TBH I was about to discuss setting permissions differently with our dev team, but that's a separate question.

You may look for the list of tasks in the repository's issue tracker:
https://github.com/adventuregamestudio/ags-manual/issues
you may open ones too if you feel the need to



The tasks we are primarily interested in are:
1) Enhancing description of the Editor and editing various items in the project. Issue: https://github.com/adventuregamestudio/ags-manual/issues/218
2) Writing thorough explanation of Game Features, basically, explaining the logic of how things work in game, how they are set up and how they behave. Issue: https://github.com/adventuregamestudio/ags-manual/issues/209
3) Expanding tutorials, explaining solutions to most typical problems (say, run continuous state update in repeatedly_execute, and other).


If you have questions or suggestions, please contact us in this forum thread, at the issue tracker or AGS Discord (there's a channel dedicated to documentation). You may also send me a PM, although I'd prefer to keep the discussion public.

This question is partially about syntax and partially about a technical issue in AGS.

There is a number of languages that are written right-to-left (Arabic, Persian, Hebrew, few others).

AGS has a built-in "Right to left" text mode, but it looks like it was meant strictly for ASCII method, and is not fully usable with Unicode texts. The thing is that unicode texts may already be written right-to-left (they may contain control characters for this, if I understand correctly).

The problem with AGS though is that the way it wraps the text assumes the text was originally written left-to-right (in script or translation files). In the Right-to-left mode the engine will wrap the text same way as for left-to-right, but then reverse each line separately.

This does not work at all with "proper" R-to-L Unicode texts. As they already are reversed, the line splitting may result in beginning of the sentence appearing on the last line.

My first thought was that a fix should simply be to revert the order of the split lines instead.
Or, more correctly: do the line splitting by scanning the text in reverse.

But then I started considering things like multiple sentences in the same string, or even multiple paragraphs in the same string, and got very confused.

My question is: supposing you have 2 sentences in, say, Arabic or Persian. How are those 2 sentences are written normally? Is their order also reversed? If yes, then the above fix will work... if not, then it won't work, because you will need to have first sentence arranged first (which may take multiple lines), then the second, and so on.

And then there's a case when you have a number of paragraphs in one string. Obviously, the order of paragraphs must not be reversed. But if a single sentence inside a paragraph is wrapped, then wrapping of that particular sentence will have to be reversed...
In other words, there may be groups of lines wrapped in reverse order, but groups themselves have to be arranged in original order...

So, thinking about this, I was coming to an idea that there's no trivial generic solution here.

Or rather, the only "trivial" generic solution is to write R-to-L languages completely left-to-right in the source texts, and let the engine revert them after splitting in lines.

Without this, the engine would have to parse the text's syntax using punctuation, finding where the sentences are (separated with fullstops), and where the paragraphs are (separated with manual linebreaks).
Well, this is not impossible, but at the same time things like that was not done in the AGS engine before.

Does anybody have ideas on this?

Summary

AGS 3.6.0 is another big change to AGS.
First of all, this release presents a SDL2-based engine. For about 2 decades AGS engine was based on Allegro 4 graphic library, which was discontinued somewhere in the early 2010-ies (only received few patches since). There was an intent to move to to Allegro 5 or SDL since, but for various reasons this task was continuously postponed. Now it's done.
Secondly the Editor and Engine now have full Unicode support. This means that you may use any language whatsoever in scripts, object descriptions and custom properties, as well as translations; so long as you also provide proper unicode fonts.
Third, we have finally expanded a list of platforms that the Editor can build for: now this includes Android and Web (Emscripten) port.

There are much more changes and improvements in this release, check out the full list of changes below.
Also, please be sure to read "Upgrading to AGS 3.6" topic in the manual: https://adventuregamestudio.github.io/ags-manual/UpgradeTo36.html




What is new in 3.6.0

Common features:
 - Full Unicode support for all game texts: game properties, scripts, translations, input.
   ASCII/ANSI mode is still working, for backwards compatibility. This may be configured in the game project.
 - Extended sprite compression options: lossless storage optimization for 16- and 32-bit sprites; LZW compression option for sprites in addition to existing RLE compression.
 - GUI controls may now be told to clip their contents, which means that nothing gets drawn outside of their borders (as defined by X, Y, Width, Height properties). The only exception is Sliders, which are more complicated.
 - The historical TTF fonts' "fixup" that altered their height and vertical offset is now optional and works only if backwards compatible option is set.
 - Max number of AudioChannels is now 16 (was 8).
 - Removed game Cursors hard limit (was 20).
 - Increased Room Objects limit to 256 (was 40).
 - Discontinued "Windows Game Explorer" support in both Editor and Engine.

Editor:
 - Editor requires .NET Framework 4.6 to run.
 - Added Android build target support (requires "Android component" installed).
 - Added Web/Emscripten build target support (requires "Web build component" installed).
 - Expanded UI color theme format, support global color options and allow missing entries.
 - Script editor works in unicode mode.
 - Added "Text format" option in General Settings which lets switching between ASCII/ANSI and Unicode (UTF-8) modes. This defines which format the game texts will be written in, when saving the game project and compiling the game.
 - Added "Use old-style keyboard handling" option to the General Settings, which lets select between classic key press handling and new one meant for unicode chars support in scripts.
 - Supports compiling UTF-8 translations. TRS file now has "Encoding" setting that tells how to interpret this TRS text.
 - Added support for building multiple speech voxes, by taking files from the Speech subfolders.
 - Added support for adding custom files into the game package. This is done by assigning a list of directories to "Package custom data folder" option in General Settings.
 - Editor now copies a acsetup.cfg file from the project's root folder (if one is provided by) as a base for generating default config file. Settings from Default Setup will be written over, but other found options won't be removed.
 - Added "Sprite file compression" option in General Settings, replacing "Compress the sprite file" option. The new option allows a selection of compression algorithm used for sprites.
   Currently supported: None, RLE (old default compression) and LZW.
 - Added "Enable sprite storage optimization" option to the General Settings, that permits the editor to repack sprites in a different storage format, reducing their disk size whenever possible. This option may be used alongside with the sprite compression. Note that this does not change how the sprites work in game.
 - Added "GUI controls clip their contents" option to the General Settings.
 - Added "TTF fonts height used in the game logic" option to the General Settings, that makes your game use real font's pixel height when arranging text and text-based UI elements, as opposed to the nominal font's size.
 - Added "Touch to Mouse Emulation", "Touch to Mouse motion mode" and "Display FPS on Screen" to Default Setup. Removed few deprecated options.
 - Added "TTF font adjustment" property to Fonts, as well as to General Settings where it serves as a project default for the new fonts. This property lets you choose between "no changes" and backward compatible TTF fixup meant to keep fonts made for AGS displayed as they were meant to.
 - In the "Import TTF" dialog added a choice to import the size closest to the given pixel height.
 - Fonts now have Auto Outline Style and Auto Outline Thickness properties.
 - Fonts now have a readonly Family Name field, that lets user see the original name of a font they've imported (if available).
 - Added IdleDelay property to Characters that lets you set time needed to pass before IdleView is activated. This is equivalent to the Character.SetIdleView script function.
 - Added Character.IdleAnimationDelay property to let setup idle view's animation speed.
 - Added Cursor.AnimationDelay property to let setup cursor's animation speed.
 - The TextWindow edges now have distinct names in the dropdown list of the property grid.
 - Rooms created from a Blank template will now have default background of a game's resolution.
 - When creating new room objects they will now have their script names set to some default value.
 - Added Room.BackgroundAnimationEnabled property to let have disabled animation on room load.
 - Editor will now create an empty sprite file if one is missing in the game project. Any existing sprite descriptions in the project will be kept, letting user to reimport these from sources.
 - Added "File -> Restore all sprites from sources" menu command.
 - Added "Apply" button on editor's Preferences dialog.
 - In Preferences replaced "Import Color Theme" with a "Open Theme Folder", as a temporary solution for managing theme files.
 - Select script editor's font in the editor's Preferences.
 - Added "Help" option to the editor pane's tab context menu.
 - Upgraded script editor to Scintilla 3.21.1 and ScintillaNET 3.6.3.
 - Cursor's position in script is now displayed on the status bar.
 - Dialog scripts now too can open help topics for keywords or script functions under cursor on F1.
 - Added zoom controls for the Sprite Manager, Character, Cursor, Inventory and View panes.
 - Sprites may now be imported by drag'n'drop into the Sprite manager.
 - In sprite manager's context menu added command "Create source files for all sprites with missing / external sources..."
 - In sprite manager's context menu added (restored) command "Replace sprite using previous files".
   Also made "previous file" remembered consistently whenever a sprite is imported or replaced.
 - In sprite manager's "export all" dialog added "skip if inside project's folder" option.
 - In sprite manager's "export all" dialog added "reset tile settings" option.
 - On the View pane the frames having set delay and linked sound will be now indicated with icons.
 - Editor no longer errors and fails when opening a game project with some script files missing.
 - Editor no longer errors on empty translations when compiling the game.
 - Editor now exports values of the string type Custom Properties to translations.
 - Editor no longer prevents exporting string arguments from Get/SetTextProperty calls to TRS file.
 - Editor now cleanups spritefile on game load, identifying any data not referenced by the project and marking it for deletion.
 - Fixed editor silently enabling all available Build Targets when upgrading a pre-3.4.0 project. This could be very inconvenient as there are several of them supported now.
 - Fixed open folders in the Project Tree were collapsing whenever you create a new subfolder or change an object's name in properties.
 - Fixed editor was not preventing from entering Character's and AudioClip's ScriptName too long for the engine to handle.
 - Fixed Image and View properties in various objects were allowing negative values.
 - Fixed some of the object previews (at least GUI) could crash if user entered a non-existing sprite's number as an Image property.
 - Fixed editor displaying unhandled exception if the script which user is trying to open was missing. Instead it will now open a blank script.
 - Fixed room editor was suggesting to save the modified room even if no changes were made.
 - Fixed a recently imported sprite could be displayed incorrectly scaled up in the room editor for high-resolution games, if the "Allow relative asset resolutions" was enabled in General Settings, and the sprite 0 had "Resolution" property set to "Low".
 - Fixed program crash occuring on sprite's import if failed to open a source file for any reason.
 - Fixed View animation preview stopping at frame 100 (if loop contains over 100 frames).
 - Fixed going to a "find all" result in dialog script did not highlight the found text, and sometimes did not scroll down to it.
 - Fixed "Goto Definition" not working for Enums and Defines (macros).
 - Fixed script autocomplete sometimes was not updated right after opening a script.
 - Fixed script autocomplete for function calls was mistreating commas in strings and inline comments as if they were separating actual parameters.
 - Fixed script autocomplete was not displaying members of extended structs if the parent struct was declared in another header.
 - Fixed script autocomplete was not working for enum names.
 - Fixed structs and enums were not highlighted if declared inside a script's body.
 - Fixed in dialogs numbers inside names were incorrectly highlighted as numeric values.
 - Fixed matching or mismatching braces were not highlighted consistently at all times in regular and dialog scripts.
 - Fixed crash occuring when user was trying to set breakpoint on the very last line in script.
 - Fixed few editor panes were not opening correct help topics in F1.
 - (Possibly) fixed error message text in the runtime error popup could be drawn partially beyond the popup borders if the user's system has text scaling option enabled.

Compiler:
 - Support unicode character literals.
 - Support using float literals when defining default values for function arguments.
 - Support hexadecimal number literals (e.g. "0xABCDEF").
 - Removed 500-characters line limit.

Script API:
 - Expanded `on_key_press` callback, now supports two parameters: key code and key modifier flags.
 - In the new key handling mode `on_key_press` is called for each actual key press;
   e.g. combinations like Ctrl+Z will result in two `on_key_press` calls, one with eKeyCtrlLeft and second with eKeyZ; added support for "NEW_KEYINPUT_API" macro in scripts.
 - Implemented new `on_text_input(int ch)` callback which is called when the engine receives a printable character. This callback is essential for handling unicode chars in script.
 - Similarily, expanded `dialog_options_key_press` with the third `mod` argument, and implemented `dialog_options_text_input` callback for receiving unicode chars during the custom dialog options state.
 - Implemented `dialog_options_close` callback which is called when custom dialog options are removed from the screen. This allows to perform any required cleanup.
 - Added eEventEnterRoomAfterFadein event for `on_event` callback, which corresponds to "enter after fade-in" room event.
 - Added eKey constants for Shift, Control and Alt keys.
 - Added eKeyMod enum for key modifiers constants.
 - String.AppendChar(), ReplaceChar() functions and String.Chars[] property are now working with the unicode characters.
 - String.Format("%c") specifier will now be able to print unicode characters.
 - Extended Button.Animate() to have blocking style, direction and starting frame parameters, thus matching other Animate commands (of Character and Object).
 - Extended all Animate() commands by adding "volume" parameter, that defines volume of the frame-linked sounds for the duration of this animation.
 - Added Character.AnimationVolume, defining volume of the frame-linked sounds.
 - Added Character.IdleAnimationDelay to let control idle view's animation speed.
 - Character.Scaling is no longer limited by a range of 5-200 (now supports 1-32767).
 - Hotspot.Name and Object.Name may now be set in script.
 - Added Object.ManualScaling and Object.Scaling.
 - Deprecated Object.IgnoreScaling (use Object.ManualScaling instead).
 - Object.SetView default loop & frame values are now 0 (was -1 which retained loop and frame indexes from the previous view, often unexpected to the user).
 - DrawingSurface.DrawImage() and DrawSurface() now support optional source rect coordinates.
 - Added functions for getting DrawingSurface of room masks: GetDrawingSurfaceForWalkableArea(), GetDrawingSurfaceForWalkbehind(), Hotspot.GetDrawingSurface(), Region.GetDrawingSurface().
 - Added new delay parameter to Mouse.ChangeModeView() to let control cursor's animation speed.
 - Added Game.ChangeSpeechVox() and Game.SpeechVoxFilename, support switching the voice-over pack.
 - Added Mouse.AutoLock property that toggles automatic mouse lock inside the game window.
 - Added Room.Exists().
 - Added System.Log().
 - Added SkipWait() that skips any active Wait() function.
 - Added WaitMouse() to complement existing Wait functions.
 - Added InputType enum which defines input devices and lets create their sets as flags.
 - Added WaitInput(), a more generic and extendable function that accepts a combination of flags telling which input types to wait for.
 - All Wait* functions now may have infinite timeout if you pass a negative timeout parameter.
 - All Wait* functions now return the reason they were skipped: a combination of InputType flag and a respective key or button code.
 - Added GUIControl.Transparency property.
 - Added Overlay.CreateRoomGraphical and CreateRoomTextual. Use these two functions to create "room overlays": that is - overlays that display a sprite inside the room, sorted among other room objects, characters and walk-behinds.
 - Added readonly Overlay.InRoom property that tells if this is a room or screen overlay.
 - Extended Overlay.CreateGraphical() with a new "clone" parameter that tells whether to assign a sprite index, or make a sprite's copy owned exclusively by this overlay. The former will save program memory but make overlay update if the sprite is edited later. The latter is meant primarily for backwards compatibility.
   Overlay.CreateRoomGraphical has the same param.
 - Added Overlay.Graphic property that lets you change overlay's sprite after it's created.
 - Added Overlay.Width and Height properties, that let you freely scale existing Overlay.
 - Added readonly Overlay.GraphicWidth and GraphicHeight properties that let read original overlay's graphic size, as not all overlays hold a sprite reference (e.g. textual overlays).
 - Added Overlay.Transparency property.
 - Added Overlay.ZOrder property that lets you sort Overlays among themselves and other objects in the same "game layer": screen overlays are sorted among GUI, while room overlays are sorted among room objects, characters and walk-behinds.
 - Added Speech.TextOverlay and Speech.PortraitOverlay for accessing blocking speech overlay and portrait overlay respectively.
 - Added Game.BlockingWaitSkipped which tells the result of the last blocking wait skipping, also including result of the blocking speech skipping.
 - SkipSpeechStyle now supports eSkipNone mode; when used it will disable any kind of skipping, such speech can be only skipped by a direct command from script.
 - Extended Screen.ScreenToRoomPoint() with an optional "restrictToViewport" argument, which lets to choose whether tests over empty place result in conversion through the default viewport or a null pointer.
 - Added AudioClip.PlayOnChannel().
 - Added AudioChannel.Pause() and Resume() functions, and IsPaused property.
 - Added AudioChannel.SeekMs(), complementing PositionMs (as the Seek() function interprets position differently depending on the audio format).
 - PlayVideo() now supports an option to play both game's and video's audio track simultaneously.
 - Added File.WriteRawInt() to complement ReadRawInt().
 - File paths in script now support $DATA$ token, which tells to read files from the game package. This only works for read operations. Functions that support this token currently are:
   File.Open(), DynamicSprite.CreateFromFile(), ListBox.FillDirList().
 - Debug(2, 0) command that displayed walkable areas is superceded by Debug(2, n), where "n" is a mask type: 0 - none, 1 - hotspots, 2 - walkbehinds, 3 - walkable areas, 4 - regions. This command also works as a toggle switch, calling it with the same mask index will turn it off.
 - Debug(5, n) command that displayed character's walk paths now also works as a toggle switch.

Engine:
 - New SDL2-based backend for graphics, audio and input.
 - Hqx graphic filters discontinued (could be temporary).
 - Windows-only DirectMedia video playback discontinued (could be temporary).
   Only OGG/OGV videos are kept supported at this point.
 - Support resizing game window on desktop systems.
 - Support "borderless full-screen window" mode in addition to the real (exclusive) fullscreen.
 - Support for switching vertical sync at runtime with Direct3D/OpenGL renderers. Also enable vsync in windowed mode too.
 - Unicode (UTF-8) text support: engine can now switch between ASCII and UTF-8 text mode. This is controlled by both game's OPT_GAMETEXTENCODING setting and translation's "Encoding" setting: they tells whether to interpret game texts as UTF-8 or ASCII/ANSI.
 - Support optional translation's "GameEncoding" setting: it hints the original game's codepage to help with their conversion. This is mostly meant for translating existing older (ANSI) games.
 - Engine now supports using real pixel height of the TTF fonts when arranging text and UI elements on screen; using nominal import size of the font is used as a compatible mode for the old games.
 - Also supports separate "normal" and backward compatible "fixup" modes when initializing TTF fonts, letting to display both common TTFs and ones made specifically for AGS in the past to display as they were meant to be.
 - Supports scripts using functions and variables from any other scripts, regardless of the script module order in the project.
 - Removed limit of simultaneous Button animations.
 - Removed limit of Character followers.
 - Removed Overlay limit.
 - Character.SetWalkSpeed() is no longer restricted by an arbitrary limit of 50.
 - Process character's idle view based on real game speed, not hardcoded 40 fps.
 - Improved file writing times (e.g. when doing a game save) by using buffered file stream. Initial tests showed 50% faster file writing.
 - Engine now renders GUI controls as separate textures when using hardware accelerated renderers. This may significantly improve performance in the high-resolution games and games with large number of GUI elements on screen.
 - Engine now shares the video texture data for all game objects on screen sharing same sprite. This improves performance in case there are multiple objects which use same image.
 - Various performance optimizations for both raw drawing and texture updates (Direct3D/OpenGL).
 - Engine now ensures that in threaded audio mode the AudioChannel's state only changes once the game is updated, and not while the game script is running. This prevents situations when the clip could begin playing before all properties are set in script, or when AudioChannel's properties' values (such as Position) could change while running a game script.
 - 24-bit wav PCM support, comes with the new sound library.
 - File.ReadRawLineBack() now always reads full line, and not limited to 200 characters anymore.
 - Debug displays, such as showing room mask and character walk paths, are now implemented as non-blocking translucent overlays, allowing you to keep playing the game while they are on.
 - Implemented debug key controls for calling a built-in save and restore game dialogs. These controls have to be set in user config as "save_game_key" and "restore_game_key" in "[override]" category. These may be used by testers if the game is missing a save function or one is bugged.
 - Engine now supports loading compiled scripts as separate files packed along with the game, along with those embedded into the main game data or inside room files.
 - Engine no longer bails out with error if the chosen translation cannot be loaded on startup.
 - When reporting script errors, engine will print callstack for all the active script "threads": for example, if there's Wait() function called and error happened in repeatedly_execute_always, then it will print both actual error's location, and Wait() call's location.
 - Engine config now has graphic modes defined as a simplier string options: "[graphics] fullscreen" for the fullscreen mode setup, and "[graphics] window" for the windowed.
   Fullscreen option can explicitly define a "borderless full-screen window" mode.
 - Added "emul_mouse_mode" and "emul_mouse_relative" options to config in "[touch]" category.
 - Added "cache_size" and "stream_threshold" options to config in "[sound]" category, they setup the rules for sound caching and choosing whether to load a clip fully into mem or stream one.
 - Added "load_latest_save" and "show_fps" options to config in "[misc]" category.
 - Added "background" option to config in "[misc]" category, that defines the starting run-in-background (aka multitasking) mode (may later be changed by SetMultitaskingMode()).
   Added "--background" command line option for the same purpose.
 - Added "--sdl-log" command line option for setting up SDL2 library output verbosity. The engine log config now has a new "sdl" group meant for SDL2 messages.
 - Support "--user-conf-dir" command-line arg (and "user_conf_dir" config option) superceding "--localuserconf"; the new option directly tells the location of user config file.
 - Path related command-line and config options, - such as "shared_data_dir", "user_data_dir" and "user_conf_dir", now support $GAMENAME$ token in path which is resolved to the game's title.
 - Added "--clear-cache-on-room-change" command-line arg (and similar config option).
 - Don't error when DrawingSurface.DrawImage has bad transparency parameter (warning instead).
 - Don't error when detecting bad format in File.Read* functions (warning instead).
 - Added stubs for agsshell plugin (a contemporary cross-platform variant of ags_shell).
 - Added stubs for agsappopenurl plugin.
 - Fixed potential crashes if a room-related API function has been called in "game_start"; this is achieved by having a dummy room placeholder object. Still results of such calls are undefined and should not be relied upon.
 - Fixed potential crash on room load if the walkable area mask contained color values above the supported range.
 - Fixed dialog script's "goto-previous" command not working if used from the first sub-topic run using "goto-dialog" (a very-very old bug).
 - Fixed AGS_EngineInitGfx plugin callback was not called during OpenGL renderer initialization.
 - Fixed Direct3D/OpenGL renderers were displaying plugin's raw drawings in a wrong position in the scrolling rooms, if the drawing was done on AGSE_PRESCREENDRAW or AGSE_POSTROOMDRAW events.
 - Fixed overlay may fail to be created sometimes, if previously another overlay had been forcefully removed when changing rooms (this is an ancient bug which existed for many years).
 - Fixed ListBox.RowCount reporting 0 if called before the control was displayed once.
 - Fixed GetTextWidth would still return a size of an outline for an empty text string.
 - Fixed text may be misaligned in gui controls, as its outline thickness is not counted.
 - Fixed some TTF fonts could be cut at the bottom when the speech is displayed.
 - Fixed scheduled sound fadeout effect was not cancelled by skipping a cutscene.
 - Fixed OGV Theora videos positioned incorrectly if they have certain sizes or aspect ratios.
 - Fixed game fps sped up if SetGameSpeed() is called repeatedly in game script.
 - Fixed game not reacting to system close commands when stuck in script, which made it impossible
   to close the "hanging" game by usual means (other than terminating the process).

Engine Plugin API:
 - Added IAGSEngine::GetGameInfo() function which returns information about the game, such as its title and GUID.
 - Added new render callback AGSE_POSTROOMDRAW, for handling drawing inside the room above all room objects.
 - Added IAGSFontRenderer2 interface, expanding the original font renderer interface, improving font plugins support.
 - Added ReplaceFontRenderer2() and NotifyFontUpdated() functions.

Compatibility:
 - Fallback to the first loop with frames if current character's loop does not have any.
 - Use the dummy frame if current character's speech view loop does not have any.
 - Ignore character having view/loop with no frames while it's not in the current room.
 - Legacy behavior of MoveCharacterBlocking's return value.
 - Fixed walkable area's continuous scaling was broken for high-res rooms in old games.
 - In pre-3.* games force player to walkable area after changing rooms, this is to emulate an unintentional effect created by the old engines.
 - Fixed pre-3.4.1 anti-aliased TTF fonts display (their vertical position was broken).
 - For pre-3.5.0 games support old behavior of coincidental dynamic sprite replacement on GUI backgrounds (and few other places) without explicit assignment; that is - when the new DynamicSprite is created right after deleting an old one.
 - Support Label.TextAlignment with legacy alignment constants for pre-3.5.0 games made with the custom engine from "Clifftop Games".
 - Support native resolution hack for games made with "Clifftop Games" custom engine, where 640x400 games are run as 640x360.

Android:
 - Rewrote universal AGS game launcher/player using up-to-date Google guidelines. The former "launcher" is now called "AGS Player".
 - Implemented single game project template meant for building your own signed APK.
 - Implemented two touch-to-mouse control scheme (selectable in config), for one finger emulating LMB only, and for two fingers emulating LMB and RMB.
 - Support relative motion speed setting for touch-to-mouse emulation.
 - In AGS Player added "Browse" button to the game folder selection, which opens default system file picker.
 - AGS Player now searches for games recursively, in all the subfolders.
 - AGS Player now has preference button per each game, which opens individual game's settings.

OSX:
 - OpenGL renderer is now supported on MacOS.

Web / Emscripten:
 - Initial port release.

Windows:
 - Installer will create program links with three-digit version in the name.
 
Plugins:
 - Added SpriteFont plugin to the list of builtins, for ports that use ones.
   SpriteFont plugin is updated to support custom "Clifftop Games" font variants.

WinSetup:
 - Added "Fullscreen as borderless window" checkbox.
 - Remade sound options to reflect the move to the new audio system in the engine.




Known issues

* Although Unicode text is supported overall, some languages may still not be printed correctly automatically. Firstly, those that require "letter linking", such as Arabic or Persian, do not have the proper linking on its own. This may be worked around using special text converters and fonts. Another issue is that texts printed right-to-left in the source (where print direction is done using Unicode's control characters) are not wrapped correctly and may require manual placement of line breaks, or scripting their split in game.
* MIDI no longer plays on its own on Windows. For MIDI you (and your players) must install "sound banks" (also known as "sound font"). Please refer to this article: https://adventuregamestudio.github.io/ags-manual/MIDI-playback.html
* AudioChannel.Position and AudioChannel.Seek do not work for MIDI and MOD sounds. Try sticking to PositionMs and SeekMs for now.
* There are reports about Direct3D not being able to restore the fullscreen mode after alt+tabbing occasionaly.
