I have a qucik question for you guys. Is there a way to change the taskbar icon? Im done with my game and im gonna show it in class on tuesday 14 and I just thought it would be cool to have an icon that represents the game and not just the standard code bit.
I tried pygame.display.set_icon(icon) but that only changed the window icon in the taskbar its still the same onld standard one.
