What AS3 code is used to loop a sound using AS3?

推荐答案

这不会给你最完美的，无缝播放，但它会导致声音循环。

This won't give you perfect, gapless playback but it will cause the sound to loop.

var sound:Sound = new Sound();
var soundChannel:SoundChannel;

sound.addEventListener(Event.COMPLETE, onSoundLoadComplete);

sound.load("yourmp3.mp3");


// we wait until the sound finishes loading and then play it, storing the
// soundchannel so that we can hear when it "completes".
function onSoundLoadComplete(e:Event):void{
    sound.removeEventListener(Event.COMPLETE, onSoundLoadComplete);
    soundChannel = sound.play();
    soundChannel.addEventListener(Event.SOUND_COMPLETE, onSoundChannelSoundComplete);
}

//  this is called when the sound channel completes.
function onSoundChannelSoundComplete(e:Event):void{
    e.currentTarget.removeEventListener(Event.SOUND_COMPLETE, onSoundChannelSoundComplete);
    soundChannel = sound.play();
}

如果你想要的声音循环多次与一个完美无瑕的，无缝播放，您可以致电

If you want the sound to loop many times with a flawless, gapless playback, you can call

sound.play(0, 9999); // 9999 means to loop 9999 times

但你的还是的需要，如果你想以后第九千九百九十九发挥无限播放设立度SoundComplete监听。用这种方式做事的问题是，如果你有暂停/重新启动声音。这将创建一个的SoundChannel其持续时间比实际的声音文件的持续时间9999倍以上，并调用播放（持续时间）时，持续时间比声音的长度会导致一个可怕的崩溃。

But you still would need to set up a soundcomplete listener if you want infinite playback after the 9999th play. The problem with this way of doing things is if you have to pause/restart the sound. This will create a soundChannel whose duration is 9999 times longer than the actual sound file's duration, and calling play(duration) when duration is longer than the sound's length causes a horrible crash.
