Question

我正在尝试将tmx文件加载到我的2D安卓游戏中，但我得到的只是一个黑屏。我甚至没有任何调试错误。我不知道它出了什么问题。 这是我的活动

    private BoundCamera mBoundChaseCamera;

    private TMXTiledMap mTMXTiledMap;

    @Override
    public Engine onCreateEngine(EngineOptions engineOptions){
        //Creating our customized engine
        return new LimitedFPSEngine(engineOptions,60) ;     
    }

    @Override

        this.mBoundChaseCamera = new BoundCamera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);

        return new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED, new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), this.mBoundChaseCamera);
    }



    @Override
    protected void onCreateResources() {

          final TMXLoader tmxLoader = new TMXLoader(getAssets(), getTextureManager(), TextureOptions.NEAREST, mEngine.getVertexBufferObjectManager());
          try {
                this.mTMXTiledMap = tmxLoader.loadFromAsset("tmx/3afak.tmx");
            } catch (TMXLoadException e) {
                e.printStackTrace();
                System.out.println("Problem in loading the tmx file");
            }   

    }   


    @Override
    public Scene onCreateScene() {

        this.mEngine.registerUpdateHandler(new FPSLogger());
        final Scene scene = new Scene();      
        this.tmxLayer = this.mTMXTiledMap.getTMXLayers().get(0);  // the 0 is just an index of the layer. It depends on how many layers you created within Tiled

        scene.attachChild(tmxLayer) ;
        scene.setScale(1.5f);



    /*  this.mBoundChaseCamera.setBounds(0, 0, tmxLayer.getHeight(), tmxLayer.getWidth());
        this.mBoundChaseCamera.setBoundsEnabled(true);
*/  

        return scene;

    }       

}

这是我的tmx文件：

我正在使用最新版本的andengine GLS2并在平板电脑上工作（zync 930 +）。

Answer 1

我禁用了背景并将sceneChildren设置为不可见，黑屏消失了。

scroll: (0.0, 0.0)
image: (0.0, 0.0)

但我仍然没有得到我应该拥有的东西。这是一个捕获：
当我尝试加载菜单场景背景时，我已经遇到了这个问题，但缩放后台精灵修复了它。在这种情况下，我不知道该怎么做，我的tmxLayer在被附加到场景之前已经缩放了!!

使用andengine加载tmx文件时为什么会出现黑屏
