pygame音乐暂停/取消暂停切换 [英] Pygame music pause/unpause toggle

问题描述

好的，这是我的代码:

def toggleMusic():

    if pygame.mixer.music.get_busy():
        pygame.mixer.music.pause()

    else:
        pygame.mixer.music.unpause()

-事件处理----

如果按"m"键，则应切换音乐是暂停还是不暂停

if pressed 'm' it should toggle whether the music is paused and not paused

toggleMusic()

它可以暂停音乐但不能取消暂停，有任何解释吗?

It can pause the music but not unpause, any explanation?

推荐答案

它不会取消暂停音乐，因为pygame.mixer.music.pause()不会影响pygame.mixer.music.get_busy()的状态.

It doesn't unpause the music because pygame.mixer.music.pause() doesn't affect the state of pygame.mixer.music.get_busy().

要获得所需的行为，您需要维护自己的变量，该变量可以跟踪暂停/未暂停状态.您可以在一堂课中做到这一点:

To get the behavior you are looking for you will need to your maintain your own variable which keeps track of the paused/unpaused state. You can do this in a class:

class mixerWrapper():

    def __init__(self):
        self.IsPaused = False

    def toggleMusic(self):
        if self.IsPaused:
            pygame.mixer.music.unpause()
            self.IsPaused = False
        else:
            pygame.mixer.music.pause()
            self.IsPaused = True
