Actionscript 3，多个音轨
Actionscript 3，多个音轨
提问于 2013-02-26 19:15:37
我在一个音乐播放器里有四种不同的音轨(吉他，贝斯，鼓，人声)。它们都被命名为复选框，用于选中/取消选中当前可听的曲目，我还有一个播放按钮可以开始播放。因此，当检查人声和吉他时，我只想听到这两种乐器和低音和鼓在背景中静音。
问题是，当我开始选中这两个框时，我不能在玩游戏时更改其他框，因为状态是静态的，并且在点击框时不会动态更改。
为了便于理解，我的代码中只有吉他和人声的摘录：
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;
