加载资源 — 音频

加载音频直接用flash.media.Sound类，它自身提供了加载机制：

package
{
	import flash.display.Sprite;
	import flash.events.Event;
	import flash.media.Sound;
	import flash.net.URLRequest;
	
	/**
	 * ...
	 * @author zhujl
	 */
	public class LoadSound extends Sprite
	{
		public var sound: Sound;
		
		public function LoadSound() 
		{
			sound = new Sound();
			sound.addEventListener(Event.COMPLETE, onLoadCompleted);
			sound.load(new URLRequest('1.mp3'));
		}
		
		public function onLoadCompleted(e: Event)
		{
			sound.play();
		}
	}
	
}
