FlashDevelop+OMSF第一个例子，关于编译常量的问题

OMSF出了1.0版，刚用FlashDevelop3.2.1来新建一个as3工程测试官方提供的代码：

public class Main extends Sprite 
	{
		private var _mediaPlayer:MediaPlayerSprite;
		
		public function Main():void 
		{
			if (stage) init();
			else addEventListener(Event.ADDED_TO_STAGE, init);
		}
		
		private function init(e:Event = null):void 
		{
			removeEventListener(Event.ADDED_TO_STAGE, init);
			// entry point
			_mediaPlayer = new MediaPlayerSprite();
			addChild(_mediaPlayer);
			
			var filePath:String = "test.flv";
			var urlResource:URLResource = new URLResource(filePath);
			_mediaPlayer.resource = urlResource;
		}
		
	}

居然报错，错误如下：

原来是编译常量问题，解决如下：

右击as3项目，选择属性，出来如下对话框：

设置Compiler Constants参数如下：

确定就ok了！有关编译常量的更多介绍可以看下面这个链接：
