AndEngine场景加载资源

Question

Help me please, wat's wrong in my code? On device shown black background.

public void onLoadResources()
{

    this.mTexture = new Texture(1024, 1024);
    this.mTextureRegion = TextureRegionFactory.createFromAsset(this.mTexture, this, "gfx/bgr.png",0,0);
    this.getEngine().getTextureManager().loadTexture(this.mTexture);
}

@Override
public Scene onLoadScene()
{
    final Scene scene = new Scene(1);
    backLayer=new Sprite(0,0,this.mTextureRegion);  
    scene.getTopLayer().addEntity(backLayer);
    return scene;
}

Answer 1

I have a few fixes for you:

1. Don't use the constructor Scene(int) , its deprecated . Use Scene() instead.
2. By your sprite's name, I guess it is your scene background? If this is your intention, you should use this: scene.setBackground(new SpriteBackground(backLayer)); , instead of scene.getTopLayer().addEntity(backLayer); .

3. Lastly, I didn't see the method createFromAsset in TextureRegionFactory . Maybe you should update your AndEngine classes? And try this instead, might work:

    BitmapTextureAtlas textureAtlas = new BitmapTextureAtlas(1024, 256, TextureOptions.BILINEAR_PREMULTIPLYALPHA); BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/"); this.mTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(textureAtlas, this, "bgr.png", 0, 0);
