循环声音flash as3

Question

我已经创建了一个打开/关闭按钮的声音使用闪光AS3。这些都是有效的，但每当我按下关闭按钮，然后是打开按钮，音乐不再播放？

我相信这是一个循环问题，但我会错吗？如果是循环问题，我不确定该使用什么代码。

我还需要为btnOn函数添加代码，因为当我打开.swf时，声音会自动播放。

下面是我的当前代码：

var mySound:Sound = new sandstorm(); //(sandstorm is my sound file)

var myChannel:SoundChannel = new SoundChannel();

var lastPosition:Number = 0;

myChannel = mySound.play();

btnOff.addEventListener(MouseEvent.CLICK, onClickPause);

function onClickPause(e:MouseEvent):void {

lastPosition = myChannel.position;

myChannel.stop();

}

干杯:)

Answer 1

你的代码只显示事件监听器的onClickPause (我想那是你的停止按钮)。但是在哪里是开始/播放按钮的事件侦听器。在play按钮上，必须再次调用play函数。这里有一个很棒的教程：http://www.republicofcode.com/tutorials/flash/as3sound/

你可以试试下面的代码。它使用一个按钮来实现音频暂停/恢复功能...

var mySound:Sound = new sandstorm(); //(sandstorm is my sound file)
var myChannel:SoundChannel = new SoundChannel();
var lastPosition:Number = 0;
var audioState : String = "paused"; //will become either "playing" or "paused"


myChannel = mySound.play(); //this line starts playback
audioState = "playing"; //update because you started playback with above line

btnOff.addEventListener(MouseEvent.CLICK, onPlayPause);


function onPlayPause(e:MouseEvent):void 
{

    if (audioState == "playing") //IF already playing
    {
        lastPosition = myChannel.position; //note current "audio time" when pausing
        myChannel.stop(); //stop playback
        audioState = "paused"; //update for next time click is used
    }
    else if (audioState == "paused") //or ELSE IF was already paused then...
    {
        myChannel = mySound.play(lastPosition); //resume playback
        audioState = "playing"; //update for next time click is used
    }

}
