Time for action – using debug draw in your Box2D project

Let's start by creating the project. In my machine, I created a game called MiniPool in my desktop. Here are the steps:

1. Open Terminal and enter the following command:

4. Drag the files GLES-Render.h and GLES-Render.cpp to your project in Xcode.
5. You can also open the Box2dTest.cpp class in the test folder Box2DTest, as we're going to copy and paste a few of the methods from there.
6. In the HelloWorldScene.h header file, leave the includes in place, but change the class declarations to match these:

   class HelloWorld : public cocos2d::Layer {
   public:
       virtual ~HelloWorld();
       HelloWorld();
       
      static cocos2d::Scene* scene();
       
       void initPhysics(...
