XNA 4.0 Game Development by Example Beginner's Guide

Time for action – handling codes

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

   #region Helper Methods
   private static void checkCurrentCellCode()
   {
       string code = TileMap.CellCodeValue(
           TileMap.GetCellByPixel(player.WorldCenter));
   
       if (code == "DEAD")
       {
           player.Kill();
       }
   }
   #endregion

2. Call checkCurrentCellCode() as the first task performed inside the if (!player.Dead) statement in the Update() method of the LevelManager class:

   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.
