提前谢谢您的时间.

如果我使用空格键发射子弹,则会创建一连串子弹.如果我在'if keys [pygame.K_SPACE]:'里面设置time.sleep()的延迟,那么它也会将循环冻结设定的秒数.我怎么能这样做,所以一次只发射一颗子弹？这是我的游戏循环的副本,请告诉我是否需要更多代码:

def game_loop():
    global pause
    x = (display_width * 0.2)
    y = (display_height * 0.2)

    x_change = 0
    y_change = 0

    blob_speed = 3

    velocity = [2, 2]

    pos_x = display_width/1.2
    pos_y = display_height/1.2

    gameExit = False
    while not gameExit:
        for event in pygame.event.get():#monitors hardware movement/ clicks
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()

        pos_x += velocity[0]
        pos_y += velocity[1]

        if pos_x + blob_width > display_width or pos_x < 601:
            velocity[0] = -velocity[0]

        if pos_y + blob_height > …
