Courses Plus Student 559 PointsI called the OnMap method but it's giving me the error message that I did not use it.
I'm stuck
namespace TreehouseDefense
{
public class Map
{
public readonly int Width;
public readonly int Height;
public Map(int width, int height)
{
if(width < 1 || height < 1)
{
throw new System.ArgumentOutOfRangeException(
"Map must be at least 1x1");
}
Width = width;
Height = height;
}
public bool OnMap(Point point)
{
return point.X >= 0 && point.X < Width &&
point.Y >= 0 && point.Y < Height;
}
}
}
using Xunit;
namespace TreehouseDefense.Tests
{
public class MapTests
{
[Fact]
public void OnMapTest()
{
int x = 2;
int y = 4;
int Width =x;
int Length = y;
var point = new Point (x, y);
var OnMap = new OnMap(Width, Length);
Assert.Equals(Width, OnMap.Width);
Assert.Equals(Length, OnMap.Length);
}
}
}
using System;
namespace TreehouseDefense
{
public class Point
{
public readonly int X;
public readonly int Y;
public Point(int x, int y)
{
X = x;
Y = y;
}
public double DistanceTo(Point point)
{
return Math.Sqrt(Math.Pow(X - point.X, 2.0) + Math.Pow(Y - point.Y, 2.0));
}
}
}

230,688 PointsYou called "OnMap" with a "new", as you might to create a new object. But "OnMap" is a method of a "Map" object, it's not an object itself.
So you'll want to create a Map object, and then call the .OnMap() method on it using your test point . And instead of testing equality, your assert should likely just see if the result is "True".
