Reset button in a c# game

Question

So, I'm making a game which is kind of similar to pac-man and I want to add a reset-button (resetting the game, NOT restarting the application). I've tried a lot of things but I still can't get it working. Any solutions?

Thanks in advance,

Henk

  .......//code missing here

   private void ResetButton_Click(object sender, EventArgs e)

      //what do I set here?

    }

Just create a new instance of Game. This will give you a whole new set of variables and therefore a new game state.

You need to keep a reference to the game to keep it from being GC'd, so you also need a static variable.

static private Game _currentGame;    

private void ResetButton_Click(object sender, EventArgs e)
{
    this.Hide();
    _currentGame = new Game();
    _currentGame.Show();
    this.Close();
}
