Time for action – handling codes

1. Add the checkCurrentCellCode() helper method to the LevelManager class:

   #Region "Helper Methods"
   Private Sub checkCurrentCellCode()
       Dim code As String = TileMap.CellCodeValue(
           TileMap.GetCellByPixel(_player.WorldCenter))
   
       If code = "DEAD" Then
           _player.Kill()
       End If
   End Sub
   #End Region

2. Call checkCurrentCellCode() as the first task performed inside the If Not _player.Dead statement in the Update() method of the LevelManager:

   checkCurrentCellCode()

3. Launch the game and run to the right until you reach an area where there are floor blocks missing, forming a pit. Jump into the pit, and your character will die when he reaches the lowest level of the pit.

What just happened?

We simply read the code value from the map for the cell where the player's WorldCenter point is located. This allows the player to get close to deadly things without actually dying, but one pixel too far will trigger the square.
