I am getting an error when compiling the code.

This is the code that I have: namespace TreehouseDefense { class Path {

   private readonly MapLocation[] _path;

   public Path(MapLocaiton[] path)
   {
     _path = path;
   }

    public MapLocation GetLocationAt(int pathStep)
    {
      return (pathStep < _path.Length) ? _path[pathStep] : null;  
    }

}

}

And the error that I get is this: Path.cs(8,20): error CS0246: The type or namespace name 'MapLocation' could not be found. Are you missing an assembly reference?

This is the code from MapLocation.cs: namespace TreehouseDefense {

class MapLocation : Point 
{

    public MapLocation(int x, int y, Map map) : base(x, y) 
    {
          if (!map.OnMap(this))
          {
              throw new OutOfBoundsException(x + "," + y + " is outside the bondaries of the map");
          }
    }
}

}

:point_right: Your build command may be incomplete.

It looks like the MapLocation.cs might not have been included in the build. Did you build using this command?

mcs *.cs -out:TreehouseDefense.exe

:point_right: Check the spelling of "MapLocation".

On line 8 of Path.cs you have "MapLocaiton" but it should be "MapLocation".
