Hello Everyone, I've been attempting to compile my Game program as described in the 2nd inheritance video but I'm encountering the following error when I try to compile the program:
"treehouse:~/workspace$ mcs -out:TreehouseDefense.exe *.cs
Game.cs(15,17): warning CS0219: The variable p' is assigned but its value is never used
Point.cs(24,31): error CS0120: An object reference is required to access non-static memberTreeh
ouseDefense.Point.X'"
Does anyone know what could be causing this?
I've taken a snapshot of my workspace so that you can reproduce the bug:
Thanks in advance.

You have a warning, and a typo:
This line in Game.cs was used in the video to demonstrate assignment of inherited types, but it was removed later. Even if left in, it does not cause an error, only a warning:
Point p = x;
In Point.cs on this line:
return DistanceTo(Point.X, point.Y);
You have written "Point.X" with a capital "P", but it should be "point.X".
