Time for action – updating Game1

1. Double-click on the Game1.cs file in the Level Editor project to open it in the editor.

2. Add the following declarations to the Game1 declarations area:

   public int DrawLayer = 0;
   public int DrawTile = 0;
   public bool EditingCode = false;
   public string CurrentCodeValue = "";
   public string HoverCodeValue = "";
   
   public MouseState lastMouseState;
   System.Windows.Forms.VScrollBar vscroll;
   System.Windows.Forms.HScrollBar hscroll;

3. Add the following lines to the Game1 constructor:

   vscroll =
       (System.Windows.Forms.VScrollBar)parentForm.Controls[
           "vScrollBar1"];
   hscroll =
       (System.Windows.FOrms.HScrolLBar)parentForm.Controls[
           "hScrollBar1"];

4. Modify the LoadContent() method of the Game1 class to read:

   protected override void LoadContent()
   {
       spriteBatch = new SpriteBatch(GraphicsDevice);
   
       Camera.ViewPortWidth = pictureBox.Width;
       Camera.ViewPortHeight = pictureBox.Height;
       Camera.WorldRectangle =
           new Rectangle(
               0,
         ...
