flex调用swf——swf可以转成具体的对象，而非MovieClip

flex builder中新建一个ActionScript工程，代码如下

package {
	import flash.display.Bitmap;
	import flash.display.BitmapData;
	import flash.events.*;
	import flash.geom.*;
	import flash.text.*;
	
	import mx.core.SpriteAsset;
	[SWF(width="80",height="100",frameRate="24")]
	public class action extends SpriteAsset
	{
		var player:Player=new Player;
		public function action()
		{
			this.addChild(player);
			
		}
		public function startGo(){
			player.startGo();
			
		}
		public function stopWalk(){
			player.stopWalk();
		}
		//根据整数调整角度
		public function setDirection(derection:int){
			player.setDirect=derection;
		}
		//计算出角度再调整角度
		public function walkAndle(radians:Number){
			player.setDirection(radians);
		}
		public function moveToNextFrame(currentFrame:int,direction:int){
			player.setCurrentFrame=currentFrame;
			player.setDirect=direction;
			player.moveToNextFrame();
		}
		public function setDisdata(simpleBitmapdata:BitmapData){
			player.simpleBitmapdata=simpleBitmapdata;
		}
		public function setAlpha(bitmap:Bitmap){
			player.simpleBitmap=bitmap;
		}
	}
}

 

  

package

}

    运行上边action.as，生成一个action.swf，可以看见一个人物一直在动。

 flex--->新建一个flex project,代码如下

 

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="testLoaderLeverType(),loa()">
	
	
		
		<mx:Script>
			<![CDATA[
				import mx.controls.Alert
				private var content:Object;//为了方便，不再用action类型,这样就不用把原来的action,和player类拷贝到这个工程下。
				private function loa(){
//					
//					Alert.show(hello.content is action);//输出true
					content=Object(hello.content);
				}
				
				var loader:Loader=new Loader;
				private function testLoaderLeverType(){
					
					loader.load(new URLRequest("action.swf"));
					loader.contentLoaderInfo.addEventListener(Event.COMPLETE,onComplete);
					
				}
				private function onComplete(event:Event){
					Alert.show(((loader.content) is action)+""); //输出true; //把上边两个类拷过来测试一下，是否为true
				}
			]]>
		</mx:Script>
		<mx:VBox>
			<mx:SWFLoader x="50" y="60" source="action.swf" width="80" height="91" id="hello">
			
			</mx:SWFLoader>
			<mx:HBox>
				
			<mx:Button click="content.stopWalk()" label="停止">
			
			</mx:Button>
			<mx:Button click="content.startGo()" label="行走">
			
		    </mx:Button>
		    <mx:Button click="content.setDirection(0)" label="向下">
		    	
		    </mx:Button>
		    <mx:Button click="content.setDirection(1)" label="向左">
