Time for action – the TileMap module – part 1

1. In the Tile Engine project, rename the Class1.vb file that was generated by the Game Library project template to TileMap.vb by right-clicking on Class1.vb and selecting Rename.

2. Double-click on the newly renamed TileMap.vb file to open it in the editor.

   Imports System.Runtime.Serialization.Formatters.Binary
   Imports System.IO
   
   Public Module TileMap

   #Region "Declarations"
     Public Const TileWidth As Integer = 48
     Public Const TileHeight As Integer = 48
     Public Const MapWidth As Integer = 160
     Public Const MapHeight As Integer = 12
     Public Const MapLayers...
