pygame中的暂停系统[重复]

Question

嗨，我花了几个小时试图在 pygame 中进行切换暂停，您按空格键并暂停，然后您再次按空格键取消暂停，我没有运气，任何人都可以帮助我请?

  ############### 2nd attempt ############# 
 global timedelay

        timedelay = pygame.time.wait (0)
        pause = 0

        if event.type == KEYUP:
            if event.key == K_p  and pause == 0:
                timedelay = pygame.time.wait (9999)
                pause = 1
                if event.key == K_p  and pause == 0:
                    timedelay = pygame.time.wait (0)
                    pause = 0
        timedelay


        ############### 1st attempt #############       
        if event.type == KEYDOWN:   
            pause = 0
            if event.key == K_p and pause == 0:
                while 1: 
                    pause = 0
                    event = pygame.event.wait()
                    pause = 1
                    if event.type == KEYDOWN:
                        if event.key == K_p  and pause == 0:
                            print "woo!"
                            pause = 0
                            break

不要阻止整个主循环运行，只需跳过循环的状态更改部分即可。您仍然需要能够响应事件，否则您的应用“无响应”。您还希望继续绘图，因为窗口可以四处移动并覆盖您的游戏，并且屏幕仍需要刷新。所以：

game_over = False
paused = False
while not game_over:
    # handle events
    for event in pygame.event.get():
        if event.type == KEYDOWN:
            paused = False
            if event.key == K_p:
                paused = True
        ...
    if not paused:
        # handle game state change
    # handle screen drawing
    pygame.display.flip()
