window_set_icon (GameMaker,C#,Unity)

Quick links: Source code

This small extension allows you to dynamically change window icon (also seen in taskbar) and taskbar badges (commonly used for notifications and such) in your GameMaker games.

Functions (GameMaker):

• window_set_icon(path_to_ico)
  Changes the window icon. Path should point to a valid ICO file.
• window_set_icon_buffer(buffer_with_an_ico_inside)
  Changes the window icon. The buffer should contain a valid ICO file.
• window_set_icon_surface(surface, set_big_icon)
  Changes the window icon to match the pixels in a surface.
  "big" (32x32) icon may used for display in taskbar.
• window_reset_icon()
  Resets the window icon to whatever it was on game start.
• window_set_overlay_icon(path_to_ico, ?description)
  Changes the little overlay/notification badge icon shown in the corner of the window. Path should point to a valid ICO file.
• window_set_overlay_icon_buffer(buffer_with_an_ico_inside, ?description)
  Changes the little overlay/notification badge icon shown in the corner of the taskbar button. The buffer should contain a valid ICO file.
• window_set_overlay_icon_surface(surface, ?description)
  Changes the little overlay/notification badge icon shown in the corner of the taskbar button to match pixels in a surface.
• window_reset_overlay_icon()
  Resets/removes the little overlay/notification badge icon.

Functions (C#):

• WindowIconTools.SetIcon(texture2d or null, kind)
  Changes small or big icon for the window to match the given texture with format=BGRA32.
  In non-Unity C#, you provide an array of bgra bytes, width, and height instead of a texture.
• WindowIconTools.SetOverlayIcon(texture2d or null, opt. description)
  Changes the overlay icon in the taskbar.
• WindowIconTools.SetProgress(progressState, numCompleted, numTotal)
  This is an equivalent of the other extension I made and is only here because it didn't really "cost" anything to add.

So, for example, if you had a "some.ico" in your Included Files, you could do

window_set_icon("some.ico");

Have fun !

Texture2D ConvertTexture(Texture2D texture, TextureFormat format) {
    var tex = new Texture2D(texture.width, texture.height, format, false);
    tex.SetPixels32(texture.GetPixels32());
    return tex;
}
