A few years ago, Josip M decided to try his hand at building games using C# and the XNA framework. He started implementing the classic board game, Nine Mens Morris, but like most side projects, he lost interest and mostly forgot about it…

…until a few months ago, when he started cleaning up his hard drive, and found the code again. Then he remembered why he lost interest and abandoned the project:

if (Mouse.GetState().LeftButton == ButtonState.Pressed && PositionPhase == true)
            {
                #region Positions
                            // First line
                            if (Mouse.GetState().X > ((int)(175 * GraphicScale)) && Mouse.GetState().X < ((int)(325 * GraphicScale)) && Mouse.GetState().Y > ((int)(175 * GraphicScale)) && Mouse.GetState().Y < ((int)(325 * GraphicScale)) && PlayerTurn == 1 && FigurePlacement[0, 0] == '\0') { FigurePlacement[0, 0] = '1'; ++FigureCount1; PlayerTurn = 2; }
                            else if (Mouse.GetState().X > ((int)(175 * GraphicScale)) && Mouse.GetState().X < ((int)(325 * GraphicScale)) && Mouse.GetState().Y > ((int)(175 * GraphicScale)) && Mouse.GetState().Y < ((int)(325 * GraphicScale)) && PlayerTurn == 2 && FigurePlacement[0, 0] == '\0') { FigurePlacement[0, 0] = '2'; ++FigureCount2; PlayerTurn = 1; }
                            else if (Mouse.GetState().X > ((int)(925 * GraphicScale)) && Mouse.GetState().X < ((int)(1075 * GraphicScale)) && Mouse.GetState().Y > ((int)(175 * GraphicScale)) && Mouse.GetState().Y < ((int)(325 * GraphicScale)) && PlayerTurn == 1 && FigurePlacement[3, 0] == '\0') { FigurePlacement[3, 0] = '1'; ++FigureCount1; PlayerTurn = 2; }
                            else if (Mouse.GetState().X > ((int)(925 * GraphicScale)) && Mouse.GetState().X < ((int)(1075 * GraphicScale)) && Mouse.GetState().Y > ((int)(175 * GraphicScale)) && Mouse.GetState().Y < ((int)(325 * GraphicScale)) && PlayerTurn == 2 && FigurePlacement[3, 0] == '\0') { FigurePlacement[3, 0] = '2'; ++FigureCount2; PlayerTurn = 1; }

Its worth noting that XNA has a Rectangle structure and a Contains method which would have greatly simplified this code. At least Josip learned from the error of his ways.
