[in4core]

public class BGSound extends Object
	{
		private var _req:URLRequest;
		private var _snd:Sound = new Sound();
		private var _chn:SoundChannel;
		private var _context:SoundLoaderContext;
		private var _isLoaded:Boolean = false;
 
		public function BGSound(soundFile:String):void 
		{
 
			_req = new URLRequest(soundFile);
			_context = new SoundLoaderContext(0, false);
			_snd.load(_req,_context); // Evil Line !!!
			_snd.addEventListener(Event.COMPLETE , onSoundLoaded)
		}
