Time for action – implementing loading and saving

1. In the Tile Engine project, open the TileMap.vb module file.

2. Add the Loading and Saving Maps region to the TileMap module:

   #Region "Loading and Saving Maps"
     Public Sub SaveMap(fileToSave As FileStream)
       Dim formatter As BinaryFormatter = new BinaryFormatter()
       formatter.Serialize(fileToSave, mapCells)
       fileToSave.Close()
     End Sub
   
     Public Sub LoadMap(fileToLoad As FileStream)
       Try
         Dim formatter As BinaryFormatter = new BinaryFormatter()
         mapCells = CType(formatter.Deserialize(fileToLoad),MapSquare(,))
         fileToLoad.Close()
       Catch
         ClearMap()
       End Try
     End Sub
   
     Public Sub ClearMap()
       For x As Integer = 0 To MapWidth - 1
         For y As Integer = 0 To MapHeight - 1
           For z As Integer = 0 To MapLayers - 1
             mapCells(x, y) = New MapSquare(2, 0, 0, "", True)
           Next
         Next
       Next
     End Sub
   #End Region

3. Back in the Level Editor project, open the MapEditor form in Design mode.
