    auto listener = EventListenerTouchAllAtOnce::create();
    listener->onTouchesMoved = CC_CALLBACK_2(Parallax2::onTouchesMoved, this);
    _eventDispatcher->addEventListenerWithSceneGraphPriority(listener, this);
    
    // Top Layer, a simple image
    auto cocosImage = Sprite::create(s_Power);
    // scale the image (optional)
    cocosImage->setScale( 2.5f );

    cocosImage->setAnchorPoint( Vec2(0,0) );
    
    
    // Middle layer: a Tile map atlas
    auto tilemap = TileMapAtlas::create(s_TilesPng, s_LevelMapTga, 16, 16);
    tilemap->releaseMap();
    
    // change the transform anchor to 0,0 (optional)
    tilemap->setAnchorPoint( Vec2(0, 0) );
    
    // Anti Aliased images
    tilemap->getTexture()->setAntiAliasTexParameters();
    
    
    // background layer: another image
    auto background = Sprite::create(s_back);
    // scale the image (optional)
    background->setScale( 1.5f );
    // change the transform anchor point (optional)
    background->setAnchorPoint( Vec2(0,0) );
    
    
    // create a void node, a parent node
    auto voidNode = ParallaxNode::create();
    
    // NOW add the 3 layers to the 'void' node
    
    // background image is moved at a ratio of 0.4x, 0.5y
    voidNode->addChild(background, -1, Vec2(0.4f,0.5f), Vec2::ZERO);
    
    // tiles are moved at a ratio of 1.0, 1.0y
    voidNode->addChild(tilemap, 1, Vec2(1.0f,1.0f), Vec2(0,-200) );
    
    // top image is moved at a ratio of 3.0x, 2.5y
    voidNode->addChild( cocosImage, 2, Vec2(3.0f,2.5f), Vec2(200,1000) );
    addChild(voidNode, 0, kTagNode);
}

引用了 kTagNode, onTouchesMoved(), s_back, s_LevelMapTga, s_Power , 以及 s_TilesPng.
