Time for action – random wall placement

1. Add the GenerateRandomMap() method to the TileMap class:

   #region Map Generation
   static public void GenerateRandomMap()
   {
       int wallChancePerSquare = 10;
   
       int floorTile = rand.Next(FloorTileStart, FloorTileEnd + 1);
       int wallTile = rand.Next(WallTileStart, WallTileEnd + 1);
   
       for (int x = 0; x < MapWidth; x++)
           for (int y = 0; y < MapHeight; y++)
           {
               mapSquares[x, y] = floorTile;
   
               if ((x == 0) || (y == 0) || 
                   (x == MapWidth - 1) || (y == MapHeight - 1))
               {
                   mapSquares[x, y] = wallTile;
                   continue;
               }
   
               if ((x == 1) || (y == 1) || 
                   (x == MapWidth - 2) || (y == MapHeight - 2))
               {
                   continue;
               }
   
               if (rand.Next(0, 100) <= wallChancePerSquare)
                   mapSquares[x, y] = wallTile;
           }
   }
   #endregion

2. Modify the Initialize() method of the TileMap class...
