Pygame 音乐暂停/取消暂停切换

Question

Okay here's my code:

def toggleMusic():

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

    else:
        pygame.mixer.music.unpause()

---event handling---

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

toggleMusic()

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

Answer 1

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

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

Answer 2

Had the same problem. For others' reference, my solution was to use a simple class.

class Pause(object):

    def __init__(self):
        self.paused = pygame.mixer.music.get_busy()

    def toggle(self):
        if self.paused:
            pygame.mixer.music.unpause()
        if not self.paused:
            pygame.mixer.music.pause()
        self.paused = not self.paused

# Instantiate.

PAUSE = Pause()

# Detect a key. Call toggle method.

PAUSE.toggle()

this one is good, i use it for games

is_paused = False

def toggle_pause():
    global is_paused
    if is_paused == True:
        is_paused = False
    else:
        is_paused = True

wn.listen()
wn.onkeypress(toggle_pause, " ")

while True:
    if not is_paused:
        bob.fd(1)
        bob.lt(1)
    else:
        wn.update()
