[CS3] how to know if my sound is playing or finished playing?

[deluxmilkman]

I`m loading and playing sound like below.

//SOUND LOAD

var snd:Sound = new Sound();
snd.load(new URLRequest("sound.mp3"));
snd.addEventListener(IOErrorEvent.IO_ERROR, onIOError, false, 0, true);
snd.addEventListener(Event.COMPLETE, onSoundLoadComplete, false, 0, true);

function onIOError(evt:IOErrorEvent):void{
	trace("sound loading error: ",evt.text);
}

function onSoundLoadComplete(evt:Event):void{
	trace("sound loaded");
}

//SOUND PLAY

snd_btn1.addEventListener(MouseEvent.MOUSE_OVER,sndPlay);

function sndPlay(evt:Event):void{
	
	var channel:SoundChannel
	channel = snd.play(); 
}

i would like to have my sound to play only when it`s not already playing.
how can I achieve this?

thank you

There is an onSoundStart method you could use. I don't know AS3 real well but I assume it looks like the other onSoundComplete functions. When you call the onSoundStart set a boolean to true, then inside of your sndPlay check it. Add this:

snd.addEventListener(Event.START, onSoundStart, false, 0, true);

function onSoundStart(evt:Event){
    evt.target.isStarted = true;
} 

and change this:

function sndPlay(evt:Event):void{
    if(!evt.target.isStarted){
       var channel:SoundChannel
       channel = snd.play(); 
      }
} 

Again, I'm no as3 guru so it may not be completely right on the addEventListener part so you may check with the help files on that.
