    screen = pygame.display.set_mode(size)
    pygame.display.set_caption("酷酷的爆炸效果类Pygame版 by lixingqiu")

    images = [f"frames/{i}.gif" for i in range(6)]
    images = [pygame.image.load(im) for im in images]

    pygame.time.set_timer(USEREVENT,randint(10,100))
    clock = pygame.time.Clock()

    running = True
    while running:

        group.update()
        screen.fill((60,0,160))
