安卓游戏引擎AndEngine的背景图像

Question

最近我开始使用AndEngine。在这方面很难找到最新的文档/帮助材料。我试图通过查看示例和源代码设置背景图像。但是由于某种原因，屏幕仍然是空白的。我无法找到任何有用的相关信息。以下是代码：

public class AndEngineActivity extends BaseGameActivity {

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

    private Camera mCamera;
    private TextureRegion mBgTexture;
    private BitmapTextureAtlas mBackgroundTexture;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    @Override
    public Engine onLoadEngine() {
        // TODO Auto-generated method stub
        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() {
        // TODO Auto-generated method stub
        BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");

        this.mBackgroundTexture = new BitmapTextureAtlas(1024, 1024, TextureOptions.DEFAULT);
        mBgTexture = BitmapTextureAtlasTextureRegionFactory.createFromAsset(this.mBackgroundTexture, this, "background.png", 0, 0);

        this.mEngine.getTextureManager().loadTextures(this.mBackgroundTexture);

    }

    @Override
    public Scene onLoadScene() {

        this.mEngine.registerUpdateHandler(new FPSLogger());

        final Scene scene = new Scene();
        final int centerX = (CAMERA_WIDTH -
                mBgTexture.getWidth()) / 2; final int centerY = (CAMERA_HEIGHT -
                mBgTexture.getHeight()) / 2;
        SpriteBackground bg = new SpriteBackground(new Sprite(centerX, centerY, mBgTexture));
        scene.setBackground(bg);

        return scene;
    }

    @Override
    public void onLoadComplete() {
        // TODO Auto-generated method stub

    }
}

Answer 1

你需要删除：

。

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

请使用以下代码：

CCSprite background=CCSprite.sprite("car7m.jpg" );

Answer 3

不是

    SpriteBackground bg = new SpriteBackground( ... );
    scene.setBackground(bg);

尝试

    Sprite bg = new Sprite(new Sprite(centerX, centerY, mBgTexture));
    scene.attachChild(bg);

嗨，感谢您的回复，但我也尝试了那个方法，没有帮助。我是不是漏掉了什么？还有其他的想法吗？ - Mob

好消息，终于搞定了。如上所示，在onCreate（..）方法之前的附加代码中覆盖了布局。我删除了该方法，现在它可以正常工作了。 - Mob

好的，是的，你不想要那个 :-) - bos

他忘记删除setContent函数调用，该函数覆盖了SurfaceView。 - Ashraf Sayied-Ahmad
