Question

我正在Andengine为Android做一个演示，当我在Galaxy SIII上运行我的游戏时，屏幕搞砸了。有一个球，它应该反弹几次，但当我运行它时，它显示为randoms颜色，球被分成两半，并在屏幕周围。这是我的代码：

public class MainActivity extends BaseGameActivity {

    Scene scene;
    protected static final int CAMERA_WIDTH = 720;
    protected static final int CAMERA_HEIGHT = 480;
    BitmapTextureAtlas playerTexture;
    ITextureRegion playerTextureRegion;
    PhysicsWorld physicsWorld;

    @Override

        // TODO Auto-generated method stub
        Camera mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);
        EngineOptions options = new EngineOptions(true,
                ScreenOrientation.LANDSCAPE_FIXED, new RatioResolutionPolicy(
                        CAMERA_WIDTH, CAMERA_HEIGHT), mCamera);
        return options;
    }

    @Override
    public void onCreateResources(
            OnCreateResourcesCallback pOnCreateResourcesCallback)
            throws Exception {
        // TODO Auto-generated method stub

        // resources have been loaded
        pOnCreateResourcesCallback.onCreateResourcesFinished();

    }

    private void loadGfx() {
        // TODO Auto-generated method stub
        BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
        // width and height have to be power of 2^x
        playerTexture = new BitmapTextureAtlas(getTextureManager(), 64, 64);
        playerTextureRegion = BitmapTextureAtlasTextureRegionFactory
                .createFromAsset(playerTexture, this, "player.png", 0, 0);
        playerTexture.load();

    }

    @Override
    public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback)
            throws Exception {
        // TODO Auto-generated method stub
        this.scene = new Scene();
        this.scene.setBackground(new Background(0f, 125f, 58f));
        physicsWorld = new PhysicsWorld(new Vector2(0,SensorManager.GRAVITY_EARTH), false);
        this.scene.registerUpdateHandler(physicsWorld);
        createWalls();
        pOnCreateSceneCallback.onCreateSceneFinished(this.scene);

    }

    private void createWalls() {
        // TODO Auto-generated method stub
        FixtureDef WALL_FIX = PhysicsFactory.createFixtureDef(0.0f, 0.0f, 0.0f);
        Rectangle ground = new Rectangle(0, CAMERA_HEIGHT-15, CAMERA_WIDTH, 15, this.mEngine.getVertexBufferObjectManager());
        ground.setColor(new Color(15,50,0));
        PhysicsFactory.createBoxBody(physicsWorld, ground, BodyType.StaticBody, WALL_FIX);
        this.scene.attachChild(ground);

    }

    @Override
    public void onPopulateScene(Scene pScene,
            OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception {
        // TODO Auto-generated method stub
        Sprite sPlayer = new Sprite(CAMERA_WIDTH/2, CAMERA_HEIGHT/2, playerTextureRegion, this.mEngine.getVertexBufferObjectManager());
        sPlayer.setRotation(45.0f);
        final FixtureDef PLAYER_FIX = PhysicsFactory.createFixtureDef(10.0f, 1.0f, 0.0f);
        Body body = PhysicsFactory.createCircleBody(physicsWorld, sPlayer, BodyType.DynamicBody, PLAYER_FIX);
        this.scene.attachChild(sPlayer);
        physicsWorld.registerPhysicsConnector(new PhysicsConnector(sPlayer, body, true, false));
            pOnPopulateSceneCallback.onPopulateSceneFinished();

    }
}

我在S3设备上测试但是我没有发现任何闪烁。我认为你使用的是更大的图像，这很难加载到Texture.So检查一次。如果是这样，请根据图像大小更改bitmapTextureatlas输入

Andengine android中的屏幕闪烁随机颜色。怎么修？
