When Ben types “Owner->” he gets the window in VS that gives suggestions, but it doesn’t do that for me and I just get an error saying “pointer to incomplete class type is not allowed”. I’m guessing it is a version difference but it is quite annoying and I’m wondering if there is a way to make intellisense a bit less strict.
You have probably missed previous lesson, which tells about IWYU (Include what you need) update in new Unreal Engine.
Basically you have to include Actor.h in your header file
