SDL Game Development

The Game class

So, now that we have an idea of what makes up a game, we can separate the functions into their own class by following these steps:

1. Go ahead and create a new file in the project called Game.h:

   #ifndef __Game__
   #define __Game__
   
   class Game
   {
   };
   
   #endif /* defined(__Game__) */

2. Next, we can move our functions from the main.cpp file into the Game.h header file:

   class Game
   {
   public:
   
     Game() {}
     ~Game() {}
   
     // simply set the running variable to true
     void init() { m_bRunning = true; }    
   
     void render(){}
     void update(){}
     void handleEvents(){}
     void clean(){}
   
     // a function to access the private running variable 
     bool running() { return m_bRunning; }
   
   private:
   
     bool m_bRunning;
   };

3. Now, we can alter the main.cpp file to use this new Game class:

   #include "Game.h" ...
