Time for action – Game1 declarations

1. Double click on the Game1.vb file in Solution Explorer to reactivate the Game1.vb code file window.

2. Add the following declarations to the Game1 class member declaration area:

   Private _gameBoard As GameBoard
   Private gameBoardDisplayOrigin As New Vector2(70, 89)
   Private playerScore As Integer = 0
   
   Private Enum GameStates
     TitleScreen
     Playing
   End Enum
   
   Private gameState As GameStates = GameStates.TitleScreen
   
   Private EmptyPiece As Rectangle = New Rectangle(1, 247, 40, 40)
   
   Private Const MinTimeSinceLastInput As Single = 0.25
   Private timeSinceLastInput As Single = 0

What just happened?

The _gameBoard instance of GameBoard will hold all of the playing pieces, while the gameBoardDisplayOrigin vector points to where on the screen the board will be drawn. Using a vector like this makes it easy to move the board in the event that you wish to change the layout of our game screen.

As we did in SquareChase, we store the player's score and will display it in the window...
