为什么我的ITextureRegions不会显示在我的场景中

Question

我正在学习AndEngine Anchor中心，我正在通过食谱。但是我在将图像加载到屏幕时遇到了一些麻烦（代码编译很好）。试图在oncreateResources方法中加载3个矩形（30x40,40x30,70x50），代码编译，但不显示images.Thanks

public class GameActivity extends BaseGameActivity {

// The following constants will be used to define the width and height
// of our game's camera view
private static final int WIDTH = 800;
private static final int HEIGHT = 480;

// Declare a Camera object for our activity
private Camera mCamera;

// Declare a Scene object for our activity
private Scene mScene;

@Override
public EngineOptions onCreateEngineOptions() {

    // Define our mCamera object
    mCamera = new Camera(0, 0, WIDTH, HEIGHT);

    // Declare & Define our engine options to be applied to our Engine
    // object
    EngineOptions engineOptions = new EngineOptions(true,
            ScreenOrientation.LANDSCAPE_FIXED, new FillResolutionPolicy(),
            mCamera);
    engineOptions.setWakeLockOptions(WakeLockOptions.SCREEN_ON);
    return engineOptions;
}

@Override
public void onCreateResources(
        OnCreateResourcesCallback pOnCreateResourcesCallback) {
    BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");

    BitmapTextureAtlas mBitmapTextureAtlas = new BitmapTextureAtlas(mEngine.getTextureManager(), 120, 120);

    ITextureRegion mRetangleOneTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(mBitmapTextureAtlas, this, "rectangle_one.png", 10, 10);
    ITextureRegion mRetangleTwoTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(mBitmapTextureAtlas, this, "rectangle_two.png", 50, 10);
    ITextureRegion mRetangleThreeTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(mBitmapTextureAtlas, this, "rectangle_three.png", 10, 60);
    mBitmapTextureAtlas.load();
    pOnCreateResourcesCallback.onCreateResourcesFinished();
}

@Override
public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback) {
    mScene = new Scene();
    pOnCreateSceneCallback.onCreateSceneFinished(mScene);
}
@Override
public void onPopulateScene(Scene pScene,
        OnPopulateSceneCallback pOnPopulateSceneCallback) {
    pOnPopulateSceneCallback.onPopulateSceneFinished();
}

}

我还没有使用中心锚分支，但你的问题似乎是你需要用加载的ITextures创建精灵。然后，您需要在场景中附加这些精灵。
