47,913 PointsIn Map.cs
, notice that Width
and Height
are declared as readonly
. However, in Game.cs
, you seem to be trying to make a new blank Map
and then assign it a width and height after it's created. Since these properties are readonly
, this isn't possible, in order to get that part to compile, you need to move those assignments into the line where you create the map
itself, like this:
Map map = new Map(20, 30);
int area = map.Width * map.Height;
Also, while it doesn't cause any issues yet, I foresee another problem in this code's future. The namespace you've used in some of your files, doesn't match the others. For example, it's TreehouseDefense
in Game.cs
, but TreeHouseDefense
in Path.cs
. Like most other programming languages, C# is case-sensitive, so TreehouseDefense
is entirely different than TreeHouseDefense
. I'd stick to TreehouseDefense
in all your files because that's what's used in the videos, but as long as it's consistent, it doesn't really matter what you name it

740 PointsIn the Game.cs file, you need to add the values of Width and Height as parameters of the Map constructor.
Map map = new Map(8, 5);
and remove the field assignments under.
