Hi, In the following code, I am trying to run "black" screen for 3 seconds and respectively 2 seconds "white" screen. Black routine takes 3 seconds and white 2 seconds, 2 x black + white = 8 seconds which should be the expected value but when I run it I get black-white-black- white instead of black-white-black. Couldn't figure out what is wrong thus sharing the code as well ;
white = False while(end<8.00): end = time.time() - start if white: screen.fill((255, 255, 255)) time.sleep(2) else: screen.fill((0, 0, 0)) time.sleep(3) white = not white pygame.display.update() pygame.quit() -- http://mail.python.org/mailman/listinfo/python-list
