I already had a look at a similar question but his code was complete and he had done more assignments so the answer for that didn't help with mine.
Here's the snapshot for the entire thing https://w.trhou.se/ambgl9ixrd
I tried changing the "public MapLocation" in line 5 in MapLocation.cs to "public mapLocation and then I got "MapLocation.cs(5,16): error CS1520: Class, struct, or interface method must have a return type"

But in MapLocation.cs, the constructor is defined on line 5 to take only 2 arguments. It looks like it was intended to have a third parameter named "map" (of type Map):
// public MapLocation(int x, int y) : base(x, y) // original
public MapLocation(int x, int y, Map map) : base(x, y) // modified
// ^^^^^^^

Treehouse ModeratorHey Elfar Oliver!
I took a look at your workspace, so the error is pointing at this method public MapLocation(int x, int y) : base(x, y)
The error here is that it is not stating the return type. If the return type is an int
you'll need to make it public int MapLocation
if the return value is nothing, it should be public void MapLocation
etc.
Hope this helps!

3,924 PointsThanks for replying, but it didn't work. I tried int, double, void, and string. I also don't remember in which video that code was made so I'll just take a break and study something else for a couple of days

Take a look at the section on Constructor syntax in the online documentation.

3,924 PointsThank you so much(yet again)! I got the same results as the teacher from compiling after I added Map map as a 3rd argument
