Thank you, the first one is working for me - at least no problems with starting the Unreal Editor. The second doesn’t because there are no such members in AController*. The mouse cursor still disappeared at runtime, but OK I will play tomorrow.
Yes, casting… Unreal C++ is specific and I’m downloading Tom Looman’s Epic Survival Game Series to learn it. Epic Team should do something to make C++ more friendly for users, at least more updated C++ videos for beginners. It’s essential for Unity users like me.
