The room script contains script for every event in this room. If you don't put the command in a function, how should AGS know when to execute it?

You first have to create the event function with the interaction editor.
Press the  "i" button, select when your command should be executed ("Player enters screen (before fadein)" for example), add a "Run script" action and press the "Edit script..." button. A window opens where you can put your command. Close and save.

Now press the "{}" button again and you will see that your command is encapsulated by the event function.
The "{}" button exists so you can quickly see and edit every script in this room and don't have to use the interaction editor every time to access the scripts.

Was it perhaps the same problem as in this thread?:

It's the region tint that's the problem.

Look at region 0 in room 3, it's set to a Tint of (0,0,0) at 50%

However, because your game is 16-bit and the Roger sprite is 8-bit the tint cannot be applied and he's disappearing instead.

To resolve it, set the region back to have a Light Level of 100%.

If you want to use region tints/lighting, you'll need to import a 16-bit sprite instead of using Roger.

I'll look into adding some sort of check for this in the engine, because the sprite just disappearing is very unhelpful, a warning message at least would be handy.

Make a backup and try.

If you run into problems, you can try upgrading one version at a time:

16 colors (Manual -> Other Features -> Distributing your game -> Custom icon)

Check out the "AreThingsOverlapping" function in the manual.

The "game.inv_activated" variable holds the number of the inventory item the user last clicked on. So you can do
  inventory[game.inv_activated].GetPropertyText("Describe", describe);

(Btw, the noun is "description".)

[uncompressed]

Please give more details: Are there some specific situations where none of your ambient sounds play (have you tried other files as well?) or is it specific files that don't work? If so, have you tried playing these sounds normally with the PlaySound function to see if they work at all?
So are you sure it's not the sound files themselves? What file format do your files have? For example, remember that AGS only supports uncompressed PCM wave files.

Very awesome!

Only thing I've noticed is that the upper part of the front leg gets very dark too suddenly when it's moving back.
I think the dark shadow on the underside of the body wouldn't affect the leg that much since it's attached more to the side of the body.

Code: ags

// dialog script

//...

@3 // option 3
man: Ok, you can take my hook.
run-script 27
stop

//...

Code: ags

// global script

int thevariable = 0; // define global variable
export thevariable; // export variable for use in room scripts


function dialog_request(int parameter) {

  if (parameter == 27) { // if "run-script 27" used

    thevariable = 1; // or whatever

  }
//else if (parameter == xx) {

}

Code: ags

// main script header

import int thevariable; // import the variable for use in room scripts

Edit:

If you're talking about GlobalInts, you can set them directly by using the set-globalint GI VAL command, e.g.
  set-globalint 8 1
instead of the run-script command.

You can change the graphical variables used by the interaction editor via the SetGraphicalVariable function.

What I like doing is putting all my direction-independent character animations in the same view as the walking animations. That way no "changeview" is required, I can just go straight to a AnimateCharacter.

The Character.ChangeView function is intended for permanently changing a character's view. For animations, you are supposed to use Character.LockView before animating and Character.UnlockView after the animation has finished.

(Just a quick note to clarify things for any beginners reading this thread.)

I'm sure it's unrelated, I just wanted to correct Gilbert's statement.

bear in mind that variables declared inside of a function are not initialized

They are, as of AGS v2.7

Strange, works great for me together with the code from your first post.

Glad I could help.

1) Try using a truetype font like this one.

2) You have to fade manually to do that:

- Set "Room transition style" to "Instant" in the General settings.
- Create a screen-sized GUI, set its background color to 16 (black), its border color to 0, its Z-order to 0 and name it "BLACKSCREEN".
- Put this in the on_event function (menu "Script" -> "on_event"):

Code: ags

function on_event(EventType event, int data) {
  //...

  if (event == eEventLeaveRoom) {
    FadeOut(1); // increase number to increase fade-out speed
    gBlackscreen.Visible = true;
  }
  else if (event == eEventEnterRoomBeforeFadein) {
    SetGlobalInt(44, 1);
  }

  //...
}

- and this in the repeatedly_execute function ("Script" -> "repeatedly_execute"):

Code: ags

function repeatedly_execute() {
  //...

  if (GetGlobalInt(44) == 1) {
    FadeOut(64);
    gBlackscreen.Visible = false;
    Wait(1);
    FadeIn(1); // increase number to increase fade-in speed
    SetGlobalInt(44, 0);
  }

  //...
}

3.) I don't think talking animations are affected by a character's animation speed. You can change the default talking anim speed for all characters by changing the game.talkanim_speed variable in the game_start function ("Script" -> "game_start"):

Code: ags

function game_start() {
  //...

  game.talkanim_speed = 2; // default delay per frame is 5

  //...
}

You could also try clicking "SPD: 0" for all frames of your talking view and entering negative values (-3 for example: 5 + -3 = 2). Don't know if that works though.

Oh yeah, sorry, the repeatedly_execute function doesn't run when the game is blocked, only repeatedly_execute_always does.
So just try changing
  function repeatedly_execute() {
to
  function repeatedly_execute_always() {

You can also use the RAD Video Tools to convert a series of pictures into a flic ("List files...", save list, select .lst file, "Convert a file", "Output type...", ...).

The problem was probably this:

Code: ags

#sectionstart room_a  // DO NOT EDIT OR REMOVE THIS LINE
  // script for Room: Player enters screen (before fadein)
#sectionend room_a  // DO NOT EDIT OR REMOVE THIS LINE

As you see the function header
  function room_a() {
and the closing
  }
are missing. You probably accidently deleted it.

To remove a room function, always delete the corresponding "Run script" action in the interaction editor instead of just deleting the code from the room script. Otherwise the "Run script" action is linked to a non-existing function which can lead to these kind of problems.

Or try this:

Code: ags

function repeatedly_execute() {

  if (IsOverlayValid(Over)) {
    if (IsInterfaceEnabled()) GetLocationName(mouse.x, mouse.y, Name);
    else StrCopy(Name, "");
    SetTextOverlay(Over, mouse.x-25, mouse.y-18, 100, 1, 15, Name);
  }

}

I'm using  2.63 beta .

I guess the Character.PreviousRoom property is only available since the final AGS v2.7.
Try player.prevroom then. Why are you using this old beta anyway?
