def main(): global FPSCLOCK, DISPLAYSURF, BASICFONT, L_SQUIR_IMG, R_SQUIR_IMG, GRASSIMAGES pygame.init() FPSCLOCK = pygame.time.Clock() pygame.display.set_icon(pygame.image.load('gameicon.png')) DISPLAYSURF = pygame.display.set_mode((WINWIDTH, WINHEIGHT)) pygame.display.set_caption('Squirrel Eat Squirrel') BASICFONT = pygame.font.Font('freesansbold.ttf', 32)
The first several lines of the main()
function are the same setup code that we’ve seen in our previous game programs. The pygame.display.set_icon()
is a Pygame function that sets the icon in the window’s title bar (just like pygame.display.set_caption()
sets the caption text in the title bar). The single argument to pygame.display.set_icon()
is a Surface object of a small image. The ideal image size is 32 x 32 pixels, although you can use other sized images. The image will just be compressed into a smaller size to be used as the window’s icon.
