如何添加暂停菜单以及如何在暂停菜单中播放没有鼓的音乐[重复]

Question

我很想在这个游戏中添加一个暂停菜单，但是我希望当我放置暂停菜单时，音乐中的鼓声会从音乐中消失，而当我重新进入游戏时，鼓声会在音乐又开始了，这样可以吗？

有人可以帮我吗？我已经有了带鼓和不带鼓（或只有鼓）的音乐文件。

您可以使用 pygame.mixer 库，它有很多很好的选项可以同时播放多个声音并停止它们。我建议查看文档：Pygame Mixer Docs。您可以导入声音，将其放入频道，并在代码中随时启动和停止该频道。

例如： 如果你有一个名为“Drums.mp3”或其他名称的声音文件，你可以将其用作：

#get the sound file

drums = pygame.mixer.Sound('Drums.mp3')

#play it

drums.play(-1) #play it until stopped

paused = False

#Game loop

while True:
    #Other code.......
    
    if paused: #Stop it if it's paused
        drums.stop()
    elif not paused and drums.get_num_channels() == 0:
        drums.play(-1) #Start playing again

这是一个非常简单且有限的示例，但您应该明白了。同样，如果您稍微阅读文档，将很容易将其完全集成。
