给你一个参考，ok？。varmy_Sound:soundme=newsoundme();varmy_SoundChanl:SoundChannel;my_SoundChanl=my_Sound.play();btn.addEventListener(MouseEvent.CLICK,_volumejian);function_volumejian(e:MouseEvent):void{function_jian():void{varmy_transform:SoundTransform=my_SoundChanl.soundTransform;my_transform.volume-=0.1;my_SoundChanl.soundTransform=my_transform;if(my_transform.volume<0.1){my_SoundChanl.stop();my_Sound=null;}}setInterval(_jian,500);}
