FGear Vehicle Physics (v1.4)

I added the lines after line 30 in Visual Studio 2019, saved the .h file, reopened in the Unreal and can’t seem to see any changes yet. I really apologize for my newbness in C++, but what do you mean by “and compile” after making the changes and saving? I don’t have that option under Build in Visual Studio.

EDIT: Changes made to the compiler and reopened the project, but still don’t see Set Spline as an option.
