I'm still working my way through the custom dialogue tree (http://www.adventuregamestudio.co.uk/manual/ags44.htm) - but one question, what about image buttons for dialogue choices?
I imagine you could write a sprite number in the question part of the dialogue, then use this to dig the sprite out and use it for the image on the dialogue choice. But how? How do you refer to an image in the sprite file, image.Graphic? Is there a script or plugin to do this already?
I never tried doing that, so I don't have an answer for you, but AnasAbdin is doing that for his game Tardigrades: http://www.adventuregamestudio.co.uk/forums/index.php?topic=50444.0
I can't actually think of a very good way to store the sprite number for the conversation option.
My best suggestion would be to put it in the dialog option string. In dialog_options_render() you can then get it from DialogOptionsRenderingInfo.DialogToRender.GetOptionText() and parse it as an int. You'll have to turn off the "say dialog option" setting so that the line isn't actually spoken when selected, and instead put the line it represents in the dialog itself.
Edit: Oh, and to draw the sprite on your custom-rendered dialog options, you just call DrawingSurface.DrawImage() with the sprite number as the "slot" argument on the provided drawing surface (DialogOptionsRenderingInfo.Surface).
Thanks :)
Here's what I have so far:
function dialog_options_get_dimensions(DialogOptionsRenderingInfo *info)
{
// Create a 1024x128 dialog options area at (1,640)
info.X = 1;
info.Y = 640;
info.Width = 1024;
info.Height = 128;
}
function dialog_options_render(DialogOptionsRenderingInfo *info)
{
int i = 1, ypos = 0, xpos=0;
info.Surface.Clear(15);
while (i <= info.DialogToRender.OptionCount)
{
if (info.DialogToRender.GetOptionState(i) == eOptionOn)
{
String str = info.DialogToRender.GetOptionText(i);
int cur_img = str.AsInt;
info.Surface.DrawImage(xpos, ypos, cur_img);
xpos=xpos+128;
}
i++;
}
}
function dialog_options_get_active(DialogOptionsRenderingInfo *info)
{
int i = 1, xpos = 0;
// Find the option that corresponds to where the player clicked
while (i <= info.DialogToRender.OptionCount)
{
if (info.DialogToRender.GetOptionState(i) == eOptionOn)
{
if (mouse.y>info.Y && mouse.x >= xpos && mouse.x<=xpos+128)
{
info.ActiveOptionID = i;
Display("%d",info.ActiveOptionID);
return;
}
xpos+=128;
}
i++;
}
}
It displays several 128x128 images next to eachother at the bottom, each corresponding to an answer. The images have the sprite slot number as the option text. Selecting each image/answer plays a piece of pre-recorded dialog.
However, dialog_options_get_active doesn't do anything. It doesn't pick where a user clicked (wherever you click, the dialog does nothing), and it doesn't even display the active option (once you've clicked it, which it doesn't do).
Have I missed something?

dialog_options_get_active was deprecated in 3.4.0.
If you really want you may enable it in General Settings (option is called "Use old-style dialog rendering API", or something similar.
Or rather use new style API.
The online manual is outdated (it corresponds to AGS 3.2.1). I've been pointing that out many times, but it still was not updated, and I do not have any control over it.
The help file that comes with AGS Editor should contain up to date information on the topic, however.
There is also post with examples here: http://www.adventuregamestudio.co.uk/forums/index.php?topic=52499.msg636523561#msg636523561
Code updated and working :)

}
function dialog_options_mouse_click(DialogOptionsRenderingInfo *info, MouseButton button)
{
if (info.ActiveOptionID > 0) {
info.RunActiveOption();
} else {
return;
}
}
However - when I have 2 options left, it crashes. Normal behaviour is say one; then, since there's only one left, say that; quit dialog.
What actually happens is: say one; then say the other; no options left - crash.
:/

Does it tell script line where it crashes, or any other kind of error message?
Before there was nothing; now, it shows this:
"An error has occured.
ACI 3.4.0.16 NMP
Error: DoDialog: all options haave been turned off."
It just closes the program.
...it's because of the options had no Stop on them :P
Always have one Stop.
Here's the final working code - bug's that drove me insane removed - for anyone dumber even than me who wants an example :P
function dialog_options_get_dimensions(DialogOptionsRenderingInfo *info)
{
info.X = 0;
info.Y = 704;
info.Width = 1024;
info.Height = 64;
}
function dialog_options_render(DialogOptionsRenderingInfo *info)
{
int i = 1, ypos=0, xpos=0;
info.Surface.Clear(15);
while (i <= info.DialogToRender.OptionCount)
{
if (info.DialogToRender.GetOptionState(i) == eOptionOn)
{
String str = info.DialogToRender.GetOptionText(i);
int cur_img = str.AsInt;
info.Surface.DrawImage(xpos, ypos, cur_img);
xpos+=64;
}
i++;
}
}
function dialog_options_repexec(DialogOptionsRenderingInfo *info)
{
int i = 1, xpos = 0;
while (i <= info.DialogToRender.OptionCount)
{
if (info.DialogToRender.GetOptionState(i) == eOptionOn)
{
if (mouse.y >= info.Y && mouse.x >= xpos && mouse.x <= xpos+64)
{
info.ActiveOptionID = i;
return;
}
xpos+=64;
}
i++;
}
}
function dialog_options_mouse_click(DialogOptionsRenderingInfo *info, MouseButton button)
{
if (info.ActiveOptionID > 0) {
info.RunActiveOption();
} else {
return;
}
}
You also do not need:
} else {
return;
}
in the last function, because it does nothing. :)
Thankyou :)
Isn't there a module that does precisely this?
If not, then you might want to turn your script into a module, bx83
