I got so far alredy and when I compiled I got an error cs1501 from my MapLocation.cs leading back to Point.DistanceTo.

so it leads me back to my Point.DistanceTo method we created a few classes back and basecly its telling me my method only takes 1 argument I don't know how to fix it and I cant go back to find wich video was the one where we created that class so can anyone help me. I also am following along with VisualStudio and I get the same error when I compile the program but its a bit more descriptive it tell me that the is no parameter y being given to my DistanceTo method but I keep checking and I cant see why it would say that the MapLocation take both an x and y int and a Map in order to know where point should be so please if someone can help me I can send you more info or screen shots

The best way to share your project for analysis is to make a snapshot of the workspace and post the link to it here.

On line 14 of MapLocation.cs, you have this:

      return DistanceTo(location) <= range;

But "DistanceTo" is not defined to take a "MapLocation" (or "Point") argument. Instead it takes two int arguments, one for each dimension. Maybe you're at an intermediate step in the course and you're about to create an overload method that will handle that argument. But in the meantime, you could make it compile by changing that line to pass it the two arguments:

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

I got the same error you did Jose. I saw this error a while back and thought maybe Jeremy would have gotten to it but he just compiled with no errors so I am thinking he might have fixed it before and not mention it in the video. I know this because I written this part 3 or 4 times lol

I have the exact same code as Jose for he MapLocations.cs class so I am not sure why that would be the fix? Anyways in his Point.cs file he is missing the method overload 

public int DistanceTo(Point point) {
        return DistanceTo(point.xCord, point.yCord);
      }

The reason that fix worked for Jose was because he had not created the overload yet. Once the overload has been added, then the original call will compile and work as intended.

Thanks for clearing that up Steven! Makes sense to me.
