如何构建多层次的场景与AndEngine？ [英] How Do I Build Multi-Layered Scenes with AndEngine?

问题描述

我是一个小白Android开发，我想学习如何使用AndEngine。我想，其中一个精灵从前景对象背后出现，然后在捶痣消失的方式来构建一个场景。我查看了每一个示例项目，但找不到任何code，显示如何做到这一点。任何帮助是极大的AP preciated。

目前，我试图用一个精灵到前台的场景设置无济于事。

  @覆盖
    公共场景onCreateScene（）{
        this.mEngine.registerUpdateHandler（新FPSLogger（））;        最后一幕一幕=新场景（）;
        最终AutoParallaxBackground autoParallaxBackground =新AutoParallaxBackground（0，0，0，5）;
        最终VertexBufferObjectManager vertexBufferObjectManager = this.getVertexBufferObjectManager（）;
        autoParallaxBackground.attachParallaxEntity（新ParallaxEntity（0.0，新的Sprite（0，CAMERA_HEIGHT  -  this.mParallaxLayerBack.getHeight（），this.mParallaxLayerBack，vertexBufferObjectManager）））;
        autoParallaxBackground.attachParallaxEntity（新ParallaxEntity（-5.0f，新的Sprite（0，80，this.mParallaxLayerMid，vertexBufferObjectManager）））;
        autoParallaxBackground.attachParallaxEntity（新ParallaxEntity（-10.0f，新的Sprite（0，CAMERA_HEIGHT  -  this.mParallaxLayerFront.getHeight（），this.mParallaxLayerFront，vertexBufferObjectManager）））;
        scene.setBackground（autoParallaxBackground）;        最终浮动的centerX =（CAMERA_WIDTH  -  this.mFaceTextureRegion.getWidth（））/ 2;
        最终浮动centerY =（CAMERA_HEIGHT  -  this.mFaceTextureRegion.getHeight（））/ 2;
        最后面对雪碧=新的雪碧（的centerX，centerY，this.mFaceTextureRegion，this.getVertexBufferObjectManager（））;
        最后PhysicsHandler physicsHandler =新PhysicsHandler（面）;
        face.registerUpdateHandler（physicsHandler）;        scene.attachChild（面）;        最后雪碧前景=新的雪碧（的centerX，centerY，this.mFaceTextureRegion2，this.getVertexBufferObjectManager（））;
        最后PhysicsHandler physicsHandler2 =新PhysicsHandler（前景）;
        face.registerUpdateHandler（physicsHandler2）;        scene.setChildScene（前景）; //＆LT;  - 给我的错误
    返回现场;
    }
 

解决方案

如果我理解正确的话，你需要层..
您可以使用实体层：

 实体backgroundLayer =新实体（）;
backgroundLayer.attachChild（面）;实体foregroundLayer =新实体（）;
foregroundLayer.attach（前景）;scene.attachChild（backgroundLayer）;
scene.attachChild（foregroundLayer）;
 

我希望这会帮助你。

I am a noob to android development and i am trying to learn how to use AndEngine. I want to construct a scene where a sprite appears from behind an object in the foreground and then disappears in a whack-a-mole fashion. I've reviewed every example project but can't find anything code that shows how to do this. any help is greatly appreciated.

Currently, I am trying to use a sprite to set the foreground scene to no avail.

@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

If I understood correctly, you need layers.. You can use entities as layers:

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

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

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

I hope this will help you.
