Question

搜索如何更改声音的音量，我总是会感到恼火snd=new Sound(URLRequest)，然后是snd.setVolume(val)。哦，很好，但我的声音不是URLRequest，它是一个嵌入。

我做了很多随机尝试（1）无济于事。我该怎么做呢？

（1）包括将我的类转换为Sound，使用embed类作为参数创建一个Sound，~~创建一个SoundTransform并将其设置为通道~~等。

Answer 1

像这样实例化您的嵌入式类：

[Embed(source="MySound.mp3")]
public var soundClass:Class;


protected function application1_creationCompleteHandler(event:FlexEvent):void
{
    var smallSound:Sound = new soundClass() as Sound;
    var trans:SoundTransform = new SoundTransform(.01);
    smallSound.play(0,0,trans);
}

如果您真正想知道的是如果声音已经播放，如何更改音量：

[Embed(source="MySound.mp3")]
public var soundClass:Class;
public var smallSound : Sound;
public var vol : Number = 0.01;
public var trans : SoundTransform;

public var chan : SoundChannel = new SoundChannel();

protected function application1_creationCompleteHandler(event:FlexEvent):void {
    smallSound = new soundClass() as Sound;
    trans = new SoundTransform(vol);
    chan = smallSound.play(0,0,trans);
}

protected function volUp_clickHandler(event:MouseEvent):void {
    vol += .1;
    trans = new SoundTransform(vol);

    chan.soundTransform = trans;
}
