Time for action – adding the final screen sprites

The last sprites we need to create are the clouds, the bomb and shockwave, and our game state messages.

1. Back to the createGameScreen method, add the clouds to the screen:

   for (int i = 0; i < 4; i++) {
     float cloud_y = i % 2 == 0 ? _screenSize.height * 0.4f : _screenSize.height * 0.5f;
     auto cloud = Sprite::createWithSpriteFrameName("cloud.png");
     cloud->setPosition(Vec2 (_screenSize.width * 0.1f + i * _screenSize.width * 0.3f,  cloud_y));
     _gameBatchNode->addChild(cloud, kBackground);
     _clouds.pushBack(cloud);
   }

2. Create the _bomb sprite; players will grow when tapping the screen:

   _bomb = Sprite::createWithSpriteFrameName("bomb.png");
   _bomb->getTexture()->generateMipmap();
   _bomb->setVisible(false);
   
   auto size = _bomb->getContentSize();
   
   //add sparkle inside bomb sprite
   auto sparkle = Sprite::createWithSpriteFrameName("sparkle.png");
   sparkle->setPosition(Vec2(size.width * 0.72f, size.height *  0.72f));
   _bomb->addChild...
