Actionscript 3 动作脚本3，多个音频曲目

我有四个不同的轨道（吉他，贝司，鼓，人声）在一个音乐播放器。它们都被命名为复选框，用于选中/取消选中当前可听到的曲目之一，我还有一个播放按钮开始播放。因此，当检查人声和吉他时，我只想听到这两种乐器和贝司以及鼓在背景中无声地演奏

问题是，当我一开始选中这两个框时，我无法在播放时更改其他框，因为状态是静态的，在点击框时不会动态更改

仅摘录我的代码，仅使用吉他和人声，便于理解：

        var vocals:Sound = new Sound();
        var vocalsChannel:SoundChannel = new SoundChannel();
        var vocalsTransform = new SoundTransform();
        vocalsChannel.soundTransform = vocalsTransform;
        vocals.load(new URLRequest("songsample.mp3"));

        var guitar:Sound = new Sound();
        var guitarChannel:SoundChannel = new SoundChannel();
        var guitarTransform = new SoundTransform();
        guitarChannel.soundTransform = guitarTransform;
        guitar.load(new URLRequest("funky.mp3"));

        voc_mc.addEventListener(MouseEvent.CLICK, _selectedVoc);
        git_mc.addEventListener(MouseEvent.CLICK, _selectedGit);

        function _selectedVoc(e:MouseEvent):void
        {
            var bool:Boolean = e.target.selected;

            if(bool)
            {
                vocalsTransform.volume = 1;

            }
            else
            {
                vocalsTransform.volume = 0;

            }
        }


        function _selectedGit(e:MouseEvent):void
        {
            var bool:Boolean = e.target.selected;

            if(bool)
            {
                guitarTransform.volume = 1;

            }
            else
            {
                guitarTransform.volume = 0;


            }
        }

        play_mc.addEventListener(MouseEvent.CLICK,
                                 function(evt:MouseEvent)
        {
            vocalsChannel = vocals.play(0,0,vocalsTransform);
            guitarChannel = guitar.play(0,0,guitarTransform);
        })

        stop_mc.addEventListener(MouseEvent.CLICK,
                                 function(evt:MouseEvent)
        {
            vocalsChannel.stop();
            guitarChannel.stop();
        })

您需要重置频道上的soundTransform属性：

    function _selectedVoc(e:MouseEvent):void
    {
        var bool:Boolean = e.target.selected;

        if(bool)
        {
            vocalsTransform.volume = 1;

        }
        else
        {
            vocalsTransform.volume = 0;

        }
        vocalsChannel.soundTransform = vocalsTransform;
    }
