Getting an error stating "'TreehouseDefense.MapLocation' does not contain a constructor that contains '2' arguments"

Question

Hello! I'm trying to run the game in the console, however, I'm getting an error when it comes to using the constructor in the MapLocation class.

Here is the full error:

" The type TreehouseDefense.MapLocation' does not contain a constructor that takes2' arguments "

Here is the class that's presenting the error:

Game.cs:

using System;

namespace TreehouseDefense
  {
class Game
{
    public static void Main()
    {
        Map map = new Map(8, 5);

        try 
        {
            Path path = new Path(
                new [] {
                    new MapLocation(0, 2, map),
                    new MapLocation(1, 2, map),
                    new MapLocation(2, 2, map),
                    new MapLocation(3, 2, map),
                    new MapLocation(4, 2, map),
                    new MapLocation(5, 2, map),
                    new MapLocation(6, 2, map),
                    new MapLocation(7, 2, map),
                }
            );

            Invader[] invaders =
            {
                new Invader(path),
                new Invader(path),
                new Invader(path),
                new Invader(path)
            };

            Tower[] towers = {
                new Tower(new MapLocation(1, 3)),
                new Tower(new MapLocation(3, 3)),
                new Tower(new MapLocation(5, 3)),
            };

            Level level = new Level(invaders)
            {
                Towers = towers
            };

            bool playerWon = level.Play();

            Console.WriteLine("Player " + (playerWon ? "won" : "lost"));

        }
        catch (OutOfBoundsException ex) 
        {
            Console.WriteLine(ex.Message);
        }
        catch (TreehouseDefenseException) 
        {
            Console.WriteLine("Unhandled TreehouseDefenseException");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Unhandled Exception: " + ex);
        }
    }
  }
 }

Here is 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 boundaries of the map.");
          }
      }

    public bool InRangeOf(MapLocation location, int range)
    {
        return DistanceTo(location) <= range;
    }
  }
 }

Can you help me fix this problem and explain why it's doing this?

Hello Nickolans,

This error is happening because within your Main method, in the Tower array, you are supplying three new MapLocation objects, however, you are not passing the map reference to their constructor. Doing so should resolve the issue.
