[已解决]程序很短，这怎么控制不了播放遍数

wuqramy

这样

1. me_down_sound = pygame.mixer.Sound("sound/me_down.wav")
   
2. me_down_sound.set_volume(0.2)
   
3. me_down_sound.play(-1)
   

复制代码

应该会循环播放

我只想让他播放一次

直接play，不加任何参数

wuqramy

你难道就单独运行了这一点代码

230行那，飞机撞击之后，只播放一次音乐，音乐的载入在最前面

呃 飞机撞击之后 不是应该只播放一次音乐的吗

wuqramy

这样就可以
但是播放完一遍后自动退出程序
