    Game main-loop (the never ending story)

    From Ideal Winforms gameloop: Corrections and Additions I have derived my implementation of the game mainloop. The reason I prefer this one is simple: I want ‘pure’ .NET; no PInvoke if not necessary.

     

      public class TesterForm : System.Windows.Forms.Form
    
  {
    
    private enum WindowsMessage
    
    {
    
      Paint =  0x000F
    
    }
    

        private GameEngine _gameEngine;
    

            public void Initialize(GameEngine gameEngine)
    
    {
    
#if WINDOWED
    
      this.Size = new Size(640,480);
    
#else
    
      this.FormBorderStyle = FormBorderStyle.None;
    
      this.Size = Screen.PrimaryScreen.Bounds.Size;
    
#endif
    
      this.StartPosition = FormStartPosition.CenterScreen;
    
      this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.Opaque, true);
    
      _gameEngine = gameEngine;
    
      _gameEngine.Initialize(this);
    
    }
    

        private void Frame()
    
    {
    
      if(_gameEngine != null)
    
      {
    
        _gameEngine.ReadInput();
    
        _gameEngine.ProcessGamelogic();
    
        _gameEngine.Render();
    
      }
    
    }
    

        protected override void WndProc(ref Message m)
    
    {
    
      switch (m.Msg)
    
      {
    
        case (int)WindowsMessage.Paint:
    
        {
    
          Frame();
    
          break;
    
        }
    
        default:
    
        {
    
          base.WndProc(ref m);
    
          break;
    
        }
    
      }
    
    }
    
  }
    

    }


    As you can see there is no Main in this class. It is my GameEngine class (or a sub class of the GameEngine class) that contains the Main and thus is the entrypoint of the application. The GameEngine class passes an instance of itself to the Form. I think that this is a better design.

    I’ll post my GameEngine class in the near-future.
