如何正确使用触摸监听器/事件和andEngine

这个触摸事件永远不会触发缓解作用。我一直在通过例子和源代码，现在我对做我想做的最好的方法有些困惑。如何正确使用触摸监听器/事件和andEngine

我画一个精灵到现场。我希望该精灵能够通过EaseFunction移动到用户触摸事件的坐标。

这是到目前为止的代码：

private static final int CAMERA_WIDTH = 720; 
private static final int CAMERA_HEIGHT = 480; 

// =========================================================== 
// Fields 
// =========================================================== 

private Camera mCamera; 
private BitmapTextureAtlas mTexture; 
private TextureRegion mFaceTextureRegion; 
// =========================================================== 
// Constructors 
// =========================================================== 

// =========================================================== 
// Getter & Setter 
// =========================================================== 

// =========================================================== 
// Methods for/from SuperClass/Interfaces 
// =========================================================== 

@Override 
public Engine onLoadEngine() { 
    this.mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT); 
    return new Engine(new EngineOptions(true, ScreenOrientation.LANDSCAPE, new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), this.mCamera)); 
} 

@Override 
public void onLoadResources() { 
    this.mTexture = new BitmapTextureAtlas(64, 32, TextureOptions.BILINEAR); 
    this.mFaceTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(this.mTexture, this, "gfx/boxface.png", 0, 0); 

    this.getEngine().getTextureManager().loadTexture(this.mTexture); 
} 

@Override 
public Scene onLoadScene() { 
    this.getEngine().registerUpdateHandler(new FPSLogger()); 

    final Scene scene = new Scene(); 
    scene.setBackground(new ColorBackground(0.09804f, 0.6274f, 0.8784f)); 

    final int x = (CAMERA_WIDTH - this.mFaceTextureRegion.getWidth())/2; 
    final int y = (CAMERA_HEIGHT - this.mFaceTextureRegion.getHeight())/2; 
    final Sprite face = new Sprite(x, y, this.mFaceTextureRegion); 
    scene.attachChild(face); 
    face.setPosition(134, 200);

//这是我尝试实现触摸监听器和代码//是不是？

scene.setOnAreaTouchListener(new IOnAreaTouchListener() { 
     //@Override 
     public boolean onAreaTouched(TouchEvent pSceneTouchEvent,ITouchArea pTouchArea, float pTouchAreaLocalX,float pTouchAreaLocalY) { 
      if(pSceneTouchEvent.isActionDown()) { 
       int facePosX = (int) (pSceneTouchEvent.getX() - face.getWidth()/2); 
       int facePosY = (int) (pSceneTouchEvent.getY() - face.getHeight()/2); 

       face.registerEntityModifier(new MoveModifier(500, face.getX(), facePosX, face.getY(),facePosY,EaseQuadIn.getInstance())); 
      } 
      return false; 
     } 
    }); 
    return scene; 
} 


@Override 
public void onLoadComplete() { 

}

终于我很确定我需要使用pScene.registerTouchArea（face）;和 pScene.setTouchAreaBindingEnabled（true）;

任何澄清会有很大的用途。谢谢

我找到了答案。但即时新的。所以我必须等待4个小时才能回答我自己的帖子。 – 2012-02-19 06:31:44

这个作品！只是不停地挖，在这里找到了答案：HTTP：//www.andengine.org/forums/tutorials/touchevent-t1490.html

这里是完整的代码。精灵加载到页面的中心。在哪里你点击精灵将'补间'或缓解到你的触摸坐标。
