Time for action – creating the TileMap class

1. Add a new class called "TileMap" to the Robot Rampage project.

2. Add the following using directives to the top of the class file:

   using Microsoft.Xna.Framework;
   using Microsoft.Xna.Framework.Graphics;

3. Modify the declaration of the TileMap class to make it a static class:

   static class TileMap

4. Add declarations to the TileMap class:

   #region Declarations
   public const int TileWidth = 32;
   public const int TileHeight = 32;
   public const int MapWidth = 50;
   public const int MapHeight = 50;
   
   public const int FloorTileStart = 0;
   public const int FloorTileEnd = 3;
   public const int WallTileStart = 4;
   public const int WallTileEnd = 7;
   
   static private Texture2D texture;
   static private List<Rectangle> tiles = new List<Rectangle>();
   
   static private int[,] mapSquares = new int[MapWidth, MapHeight];
   
   static private Random rand = new Random();
   #endregion
   

5. Add the Initialize() method to the TileMap class:

   #region Initialization
   static public void Initialize(Texture2D...
