我的Andengine中的scene点不出来attachChild为什么

我是初学菜鸟，网上看了很多例子关于scene加载目前有两种（1）Scene.getTopLayer().addEntity(mySprite)
（2） scene.attachChild(mSprite);  
第二种不知道为什么没有此方法，Andengine  的API我看过了 确实没有attachChild方法我也很郁闷，请大虾解释下。package com.waken;import org.anddev.andengine.engine.Engine;import org.anddev.andengine.engine.camera.Camera;import org.anddev.andengine.engine.options.EngineOptions;import org.anddev.andengine.engine.options.EngineOptions.ScreenOrientation;import org.anddev.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;import org.anddev.andengine.entity.scene.Scene;import org.anddev.andengine.entity.shape.modifier.LoopShapeModifier;import org.anddev.andengine.entity.shape.modifier.RotationModifier;import org.anddev.andengine.entity.shape.modifier.SequenceShapeModifier;import org.anddev.andengine.entity.sprite.Sprite;import org.anddev.andengine.entity.util.FPSLogger;import org.anddev.andengine.opengl.texture.Texture;import org.anddev.andengine.opengl.texture.TextureOptions;import org.anddev.andengine.opengl.texture.region.TextureRegion;import org.anddev.andengine.opengl.texture.region.TextureRegionFactory;import org.anddev.andengine.ui.activity.BaseGameActivity;/*中心旋转精灵*/public class Main3 extends BaseGameActivity {        @Override        public void onLoadComplete() {                // TODO Auto-generated method stub        }        /*竖屏*/        private static final int CAMERA_WIDTH=320;//宽        private static final int CAMERA_HEIGHT=480;//高        private Camera myCamera=null;        private TextureRegion myTextureRegion=null;                @Override        public Engine onLoadEngine() {                   myCamera=new Camera(0,0,CAMERA_WIDTH,CAMERA_HEIGHT);//相机                //分辨率                RatioResolutionPolicy myRatioResolutionPolicy=new RatioResolutionPolicy(CAMERA_WIDTH,CAMERA_HEIGHT);                //引擎设置                EngineOptions myEngineOptions=new EngineOptions(true,ScreenOrientation.PORTRAIT,myRatioResolutionPolicy,myCamera);                Engine myEngine=new Engine(myEngineOptions);                                return myEngine;        }        @Override        public void onLoadResources() {        //纹理        Texture myTexture=new Texture(64,64,TextureOptions.DEFAULT);        //图片路径        myTextureRegion=TextureRegionFactory.createFromAsset(myTexture, this, "gfx/face_box.png",0,0);        getEngine().getTextureManager().loadTexture(myTexture);//加载         }        @Override        public Scene onLoadScene() {                                getEngine().registerUpdateHandler(new FPSLogger());//在log中显示FPS数                                final Scene myScene=new Scene(1);                                /*中心坐标*/                final int X=(CAMERA_WIDTH-myTextureRegion.getWidth())/2;                final int Y=(CAMERA_HEIGHT-myTextureRegion.getHeight())/2;                                final Sprite mySprite=new Sprite(X,Y,myTextureRegion);//建立精灵类                                        //循环形状修改                final LoopShapeModifier shapeModifier =new LoopShapeModifier(                        new SequenceShapeModifier(                        new RotationModifier(30, 0, 360),//以30毫秒速度顺时针旋转(0-360)                        new RotationModifier(5, 360, 0)//以5毫秒的速度逆时针旋转（360-0）                        )                        );                mySprite.addShapeModifier(shapeModifier);                myScene.getTopLayer().addEntity(mySprite);//只能用这个                                                        return myScene;        }}
