error CS0117

Getting the following error when typing trying to run code.

Game.cs(13,19): error CS0117: System.Console' does not contain a definition forWriteline'
/usr/lib/mono/4.5/mscorlib.dll (Location of the symbol related to previous error)
Map.cs(17,22): error CS1061: Type TreehouseDefence.Point' does not contain a definition forx' and no extension method x' of typeTreehouseDefence.Point' could be found. Are you missing an assembly reference?

Code is as follows: (Game.cs)

using System;

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

          Point point = new Point (4, 2);  
          bool isOnMap = map.OnMap (point);
          Console.Writeline(isOnMap);

          point = new Point (8, 5);
          isOnMap = map.OnMap (point);
          Console.WriteLine (isOnMap);
        }
    }
}

(map.cs)

namespace TreehouseDefence
{
  class Map
  {

    public readonly int Width;
    public readonly int Height;

    public Map(int width, int height)
    {
        Width = width;
        Height = height;
    }

    public bool OnMap(Point point)
    {
        return point.x >= 0 && point.X < width &&
               point.Y >=0 && point.Y < Height;

    }
  }

}

Hi there! It's correct. There is no Writeline in the System class. There is, however, a WriteLine in that class. Remember, capitalization matters here.

Hope this helps! :sparkles:

If you're still receiving an error about Point, we will need to see your code in Point.cs.

Still having the same error with the x point

namespace TreehouseDefence
{

  class Point {

    public readonly int X;
    public readonly int Y;

      public Point (int x, int y) 
      {

          X = x;
          Y = y;

      }

  }

}

Hi again! Again, capitalization is your enemy here.

You've written:

return point.x >= 0 && point.X < width &&
               point.Y >=0 && point.Y < Height;

But both X and Y should be capitalized and both Width and Height should be capitalized:

return point.X >= 0 && point.X < Width &&
               point.Y >=0 && point.Y < Height;

You simply forgot to capitalize the first X and Width.

Hope this helps! :sparkles:

You're a star.

Thank you very much.
