Python Kivy：一次播放多次声音

Question

I am using Python Kivy for an Android Game. I want to play a sound on an event

sound = SoundLoader.load("sound.wav")
def onEvent():
    sound.play()

, and It works. But now the problem: Of course an event can, and in my case will happen again before the sound is done playing from the last event. And as the sounds are based on a play/pause idea I am getting a problem playing multiple sounds of the same object at once. That can be solved like this for first:

onEvent():
    SoundLoader.load("sound.wav").play()

As this creates a new object all the time, and so is able to play it the same time another event plays the sound. But the problem using this method is quite obvious, because the sound must be loaded everytime the event occurs, and so causes a delay until it's played.

Is there a more useful way to do this?

Answer 1

You can workaround this by loading multiple instances of the sound. For instance

sounds = [SoundLoader.load("sound.wav") for _ in range(10)]
index = 0

and then

def play():
    sounds[index].play()
    index = (index + 1) % len(sounds)

The more sounds you load, the more instances you can have playing at the same time (in this example 10).
