PacMan Class Simplified and Generalized

<csharp> public enum PacManState { Spawning, Still, Chomping, SuperPacMan }

   public class PacMan 
   {

       protected PacManState _state;
       public PacManState State
       {
           get { return _state; }
           set
           {
               if (_state != value)
               {
                   this.Log(string.Format("{0} was: {1} now {2}", this.ToString(), _state, value));
                   
                   _state = value;
               }
           }
       }

       public PacMan()
       {
           
           //Set default state will call notify so make sure this.Ghosts is intitialized first
           this.State = PacManState.Still;

       }

       //Extra method for logging state change
       public virtual void Log(string s)
       {
           //nothing
           Console.WriteLine(s);
       }
   }
