SDLGraphicsEngine

A class for quickly setting up and running the SDL graphics library.

Warning

You should note that this is not intended for fast or efficient graphics manipulation. It's for ease of use in setting up the SDL library in projects that use individual pixel manipulation. Examples of projects this would be useful for are plotting the Mandelbrot set, drawing cells in cellular automata, demonstrating algorithms visually, etc. this is not suitable for making 2D or 3D games since it only provides individual pixel manipulation functionality.

How to use

A class in your main program must override the initialisation and update functions in the SDLGraphicsEngine class as below:

class GraphicsEngineRunner : public SDLGraphicsEngine
{
public:
  void OnInitialisation() override
  {
    // Initialisation instructions...
  }

  void OnUpdate() override
  {
    // Render loop instructions...
  }
private:
  // Variables go here
};

Obviously 'GraphicsEngineRunner' can be renamed to whatever you like. This custom class must then be called in the main function such as in the example given below:

int main(int argc, char* argv[])
{
  GraphicsEngineRunner program;
  program.ConstructWindow(1280, 720, "Test window");
  program.Start();
  program.CleanUp();
  return 0;
}

NOTE: the parameters of main() must be exactly as above else SDL fails to insert its own SDL_main function before it.
