# No over load for method DistanceTo

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 boundries of the map."); } }

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

}
```

}

! followed everything in the video and this problem came up can someone please tell me whats wrong?

To enable a complete and accurate analysis, make a snapshot of your workspace and post the link to it here. Also please provide a link the the course page you are working with.

Thank you very much, Steven. It means a lot that people are out there to help me learn :).

In the vidoes, the only `DistanceTo` method in the `Point` class requires both an X and a Y to be passed to it.

```return DistanceTo(Location.X, Location.Y) <= range;
```

The code you have was a mistake in the videos. He never shows it during the series, but if you download the project files, you'll find that they include a second function in the `Point` class that looks like this:

```public int DistanceTo(Point point)
{
return DistanceTo(point.X, point.Y);
}
```

## The error message seems to be correct.

In the current workspace program, there is no overload for DistanceTo that would take a single Location object argument. But I know the program evolves during the course, so perhaps you're at an intermediate stage right before one is to be made.

But for right now, you could substitute this line to call with the current requirements (Timothy was close, except for the name "location"):

```       return DistanceTo(location.X, location.Y) <= range;
```
