as3中的embed

actionscript3允许把外部swf直接用Embed标记嵌入到主类中(当然用UrlLoader动态加载也行)

关键点：

设计师把素材放入到库中时，一定要指定类名，这样代码才能创建这些类的实例。

如上图所示，这里库中放了三种基本的素材(按钮，位图，电影夹)，然后在代码中可以这样处理：

package
{
 
    import flash.display.Sprite;
    import flash.display.DisplayObject;
    import flash.display.SimpleButton;
    import flash.events.MouseEvent;
    import flash.display.MovieClip;
    import flash.display.BitmapData;
    import flash.display.Bitmap;
 
 
    public class Demo extends MovieClip
    {
        [Embed(source = "skin.swf",symbol = "ButtonPause")]
        private var ButtonPause:Class;
 
        [Embed(source = "skin.swf",symbol = "ButtonPlay")]
        private var ButtonPlay:Class;
 
        [Embed(source = "skin.swf",symbol = "LogoImage")]
        private var LogoImage:Class;
 
        [Embed(source = "skin.swf",symbol = "TestMovie")]
        private var TestMovie:Class;
 
 
        public function Demo()
        {
            init();
        }
 
        private function init():void
        {
            var btnTest:SimpleButton = new ButtonPause() as SimpleButton;
            trace(btnTest,btnTest is SimpleButton);//Demo_ButtonPause0,true
            addChild(btnTest);
            btnTest.x = btnTest.y = 50;
            btnTest.addEventListener(MouseEvent.CLICK,btnTestClick);
 
            var btnTest2:SimpleButton = new ButtonPlay() as SimpleButton;
            trace(btnTest2);//Demo_ButtonPlay1
            addChild(btnTest2);
            btnTest2.y = 50;
            btnTest2.x = 100;
            btnTest2.addEventListener(MouseEvent.CLICK,btnTest2Click);
 
 
            var bmd:Bitmap = new LogoImage() as Bitmap;
            trace(bmd);//Demo_LogoImage2
            addChild(bmd);
            bmd.x = bmd.y = 200;
 
            var testMovie:MovieClip = new TestMovie() as MovieClip;
            addChild(testMovie);
            testMovie.x = testMovie.y = 180;
            trace(testMovie);//Demo_TestMovie3
 
        }
 
        private function btnTestClick(e:MouseEvent):void
        {
            trace("btnTest 被点击了!");
        }
 
        private function btnTest2Click(e:MouseEvent):void
        {
            trace("btnTest2 被点击了!");
        }
    }
 
}

 

 

Embed 后面还跟着一个symbol属性，该属性就是指明你要调用哪一个MC，就是SWF里面的MC，记得，都要为每个MC做链接，并链接名字要与symbol里的名字致
