Python游戏无响应

Question

到目前为止，我制作这个躲闪/躲避游戏几乎完成了，我在互联网上的教程中添加了声音，但是，当我尝试运行该游戏时，当我按下按钮进行播放时，该游戏没有响应，但是当我按下鼠标按钮时，会播放声音，当我按下关闭程序的X按钮时，游戏会运行，我不知道如何在按下任何键时使程序运行在我按下鼠标按钮播放声音的同时，这是我用来执行以下操作的以下教程（“ http://programarcadegames.com/index.php?chapter=bitmapped_graphics_and_sound 。”）这是代码：

    gameOverSound.stop()   

我不知道我在做什么错，请帮帮我！ 在此方面的支持将不胜感激。

Answer 1

您有两个while True循环-一个接一个。

第一

done = False

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
        elif event.type == pygame.MOUSEBUTTONDOWN:
            click_sound.play()

在您单击“ X”按钮（ pygame.QUIT ）之前一直运行。 而且仅当您单击鼠标时它才能播放声音（ pygame.MOUSEBUTTONDOWN ）

删除此循环，并while True循环中第二秒使用if/else行。
