【问题描述】：

我是 android 开发的菜鸟，我正在尝试学习如何使用 AndEngine。我想构建一个场景，其中一个精灵从前景中的一个物体后面出现，然后以一种鼹鼠的方式消失。我已经查看了每个示例项目，但找不到任何显示如何执行此操作的代码。任何帮助是极大的赞赏。

目前，我正在尝试使用精灵来设置前景场景，但无济于事。

@Override
    public Scene onCreateScene() {
        this.mEngine.registerUpdateHandler(new FPSLogger());

        final Scene scene = new Scene();
        final AutoParallaxBackground autoParallaxBackground = new AutoParallaxBackground(0, 0, 0, 5);
        final VertexBufferObjectManager vertexBufferObjectManager = this.getVertexBufferObjectManager();
        autoParallaxBackground.attachParallaxEntity(new ParallaxEntity(0.0f, new Sprite(0, CAMERA_HEIGHT - this.mParallaxLayerBack.getHeight(), this.mParallaxLayerBack, vertexBufferObjectManager)));
        autoParallaxBackground.attachParallaxEntity(new ParallaxEntity(-5.0f, new Sprite(0, 80, this.mParallaxLayerMid, vertexBufferObjectManager)));
        autoParallaxBackground.attachParallaxEntity(new ParallaxEntity(-10.0f, new Sprite(0, CAMERA_HEIGHT - this.mParallaxLayerFront.getHeight(), this.mParallaxLayerFront, vertexBufferObjectManager)));
        scene.setBackground(autoParallaxBackground);

        final float centerX = (CAMERA_WIDTH - this.mFaceTextureRegion.getWidth()) / 2;
        final float centerY = (CAMERA_HEIGHT - this.mFaceTextureRegion.getHeight()) / 2;
        final Sprite face = new Sprite(centerX, centerY, this.mFaceTextureRegion, this.getVertexBufferObjectManager());
        final PhysicsHandler physicsHandler = new PhysicsHandler(face);
        face.registerUpdateHandler(physicsHandler);

        scene.attachChild(face);

        final Sprite foreground = new Sprite(centerX, centerY, this.mFaceTextureRegion2, this.getVertexBufferObjectManager());
        final PhysicsHandler physicsHandler2 = new PhysicsHandler(foreground);
        face.registerUpdateHandler(physicsHandler2);

        scene.setChildScene(foreground); //<--Gives me error
    return scene;
    }

【解决方案1】：

如果我理解正确的话，你需要图层.. 您可以将实体用作图层：

Entity backgroundLayer = new Entity();
backgroundLayer.attachChild(face);

Entity foregroundLayer= new Entity();
foregroundLayer.attach(foreground);

scene.attachChild(backgroundLayer);
scene.attachChild(foregroundLayer);

希望对你有帮助。
