Adventure Game Studio

And there it is. I just want to make a transparent GUI for use in a custom dialogue system - at the moment, it shows as white (BackgroundColour/BackgroundColourNumber etc. are all 0's).

Given that you want to use it for Dialogs, did you create it as TextWindow GUI? If so, have you assigned any images to the 4 corners / 4 edges / background?

Transparent is 0, so there might be something else involved here.

This is it. (ignore the cursor)

And this is the window in game (down the bottom).
I'd like for it be translucent (instead of solid white) so I can see what's behind it.

And here is the code in GlobalScript:

  info.X = 0;

  info.Width = 1366;
  info.Height = 64;
}

//----------------------------------------------------------------------------------------------------------------------

function DrawDialogOptions(DrawingSurface* ds, DialogOptionsRenderingInfo* info)
{
  int i = 1, ypos = 0, xpos = 0;

  {
    if (info.DialogToRender.GetOptionState(i) == eOptionOn)

}

// END DIALOG FUNCTIONS


The dialog was originally for 1024x768 backgrounds, now 1366x768.
It's used with 64x64 conversation images.

You have
ds.Clear(15);

15 is white. Use 0 instead, or COLOR_TRANSPARENT.

That screenshot looks pretty cool and reminds me of some timetraveling adventures :)

Thanks Khris :)
Selmiak, I have no idea what you're takling about ;)
