使用AndEngine運行簡單代碼

Question

我最近開始學習AndEngine，但是我遇到了麻煩，我正在學習有關基礎知識的教程，我想加載png image，但它給了我錯誤，而且項目是失敗。

這裏是源代碼

public class MainActivity extends BaseGameActivity { 
    protected static final int WIDTH = 800; 
    public static final int HEIGHT = 460; 
    BitmapTextureAtlas playerTexture; 
    ITextureRegion playerTexureRegion; 
    Scene scene; 

    @Override 
    public EngineOptions onCreateEngineOptions() { 
     Camera mCamera = new Camera(0, 0, WIDTH, HEIGHT); 
     EngineOptions engine = new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED, new RatioResolutionPolicy(WIDTH, HEIGHT), mCamera); 

     return engine; 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void onCreateResources(OnCreateResourcesCallback pOnCreateResourcesCallback) throws Exception { 
     // TODO Auto-generated method stub 
     loadsfx(); 
     pOnCreateResourcesCallback.onCreateResourcesFinished(); 
    } 

    private void loadsfx() { 
    // TODO Auto-generated method stub 
     BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("assets/"); 

     playerTexture = new BitmapTextureAtlas(getTextureManager(),64,64); 
     playerTexureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(playerTexture, this, "fred1.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(0,125,58)); 

     pOnCreateSceneCallback.onCreateSceneFinished(this.scene); 

    } 

    @Override 
    public Engine onCreateEngine(EngineOptions pEngineOptions) { 
     // TODO Auto-generated method stub 
     return super.onCreateEngine(pEngineOptions); 
    } 

    @Override 
    public void onPopulateScene(Scene pScene, OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception { 
     // TODO Auto-generated method stub 

     Sprite sPlayer = new Sprite(WIDTH/2, HEIGHT/2, playerTexureRegion, this.mEngine.getVertexBufferObjectManager()); 
     sPlayer.setRotation(45.0f); 
     this.scene.attachChild(sPlayer); 
     pOnPopulateSceneCallback.onPopulateSceneFinished(); 
    } 

這裏是什麼logcat的是說

請幫助我，我有一個很大的願望，瞭解發動機，但它不工作。

BitmapTextureAtlasTextureRegionFactory.setAssetBasePath(path); 

「setAssetBasePath」從「assets」目錄設置資產路徑。 在您的代碼中，精靈圖像的完整路徑必須是「/assets/assets/fred1.png」。 如果路徑爲精靈「/assets/fred1.png」只是刪除BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("assets/");
