AS3 Play＆amp;暂停当前​​（已加载）MP3（Flash CC）

Question

我有8个已加载的外部mp3，将按顺序播放。我无法想象如何暂停当前正在播放的mp3并从暂停时开始播放。我确实有代码可以暂停它，但是当点击播放按钮时，它会从头开始播放第一个mp3。

var s1:Sound = new Sound(new URLRequest("Audio Files/1.mp3"));
var s2:Sound = new Sound(new URLRequest("Audio Files/2.mp3"));
var s3:Sound = new Sound(new URLRequest("Audio Files/3.mp3"));
var s4:Sound = new Sound(new URLRequest("Audio Files/4.mp3"));
var s5:Sound = new Sound(new URLRequest("Audio Files/5.mp3"));
var s6:Sound = new Sound(new URLRequest("Audio Files/6.mp3"));
var s7:Sound = new Sound(new URLRequest("Audio Files/7.mp3"));
var s8:Sound = new Sound(new URLRequest("Audio Files/8.mp3"));
s1.addEventListener(Event.COMPLETE, doLoadComplete);
s2.addEventListener(Event.COMPLETE, doLoadComplete);
s3.addEventListener(Event.COMPLETE, doLoadComplete);
s4.addEventListener(Event.COMPLETE, doLoadComplete);
s5.addEventListener(Event.COMPLETE, doLoadComplete);
s6.addEventListener(Event.COMPLETE, doLoadComplete);
s7.addEventListener(Event.COMPLETE, doLoadComplete);
s8.addEventListener(Event.COMPLETE, doLoadComplete);

var channel:SoundChannel = new SoundChannel();

channel = s1.play();
channel.addEventListener(Event.SOUND_COMPLETE, doSoundComplete);


function doLoadComplete($evt:Event):void
    {
    trace("Song loaded.");
    }

function doSoundComplete($evt:Event):void
    {
    trace("1 done.");
    channel = s2.play();
    channel.addEventListener(Event.SOUND_COMPLETE, doSoundComplete2)
    }

function doSoundComplete2($evt:Event):void
    {
    trace("2 done.");
    channel = s3.play();
    channel.addEventListener(Event.SOUND_COMPLETE, doSoundComplete3);
    }`

这是我到目前为止所拥有的： 这会加载mp3并播放它们。暂停btn工作，但恢复音频的播放按钮给我一个错误：ReferenceError：错误＃1069：在flash.media.Sound上找不到属性0，并且没有默认值。在mp3sequence_fla :: MainTimeline / playSound（） 我的猜测是当前位置或最后位置的值不正确。

var myArray:Array=[0,1,2,3,4,5,6,7];
var i:uint=1;
var req:URLRequest = new URLRequest("mp3/"+myArray[i]+".mp3");
var VSound:Sound = new Sound();
var channel:SoundChannel = new SoundChannel();
var lastPosition:Number = 0; //last position of the sound
var curSoundIndex:int = 0;  //var to store the current sound that is playing

VSound.load(req);
channel = VSound.play();

function playSound(e:Event = null) {
    //if no sound channel, load the current sound into it
        channel = VSound[curSoundIndex].play(lastPosition);
        channel.addEventListener(Event.SOUND_COMPLETE, doSoundComplete, false, 0, true);
        lastPosition = channel.position;
    }
    function pauseSound(e:Event = null) {
    if (channel) {
        lastPosition = channel.position;
        channel.stop();
    }
}

function doSoundComplete($evt:Event):void {
    curSoundIndex++;
    if (curSoundIndex >= VSound.length) curSoundIndex = 0;
}

play_btn.addEventListener(MouseEvent.CLICK, playSound);
pause_btn.addEventListener(MouseEvent.CLICK, pauseSound);

Answer 1

要暂停声音，您可以在暂停声音时存储它的位置，并使用该变量从该位置重播。

var s:Sound = new Sound(new URLRequest("Audio Files/1.mp3"));
var channel:SoundChannel = new SoundChannel();
channel = s.play();

var pausePosition:int;
function pause():void {
    soundPosition = channel.position;
    channel.stop();
}
function resume():void {
    channel = s.play(soundPosition);
}

Answer 2

您可以存储相应position的{​​{1}}属性。我添加了一些代码来减少整个事情

SoundChannel
