Creating collections of the Cocos2d-x objects

We are going to add a particle system to our game to simulate the explosions each time the player touches a bomb. In the interest of doing this, we are going to use the Vector class located in the Cocos2d-x framework to create a collection of all the bomb objects created in our game, so that when the player touches the screen, we are going to traverse this collection to verify if the player has touched any of the bombs.

For this matter, we are going to add the bomb collection to our HelloWorldScene.h definition file as follows:

cocos2d::Vector<cocos2d::Sprite*> _bombs;
