Cast() not working

auto player1 = Cast(NewPlayer);

Thats the right way =)

Did you try to Call any AMyPlayerController specific Function? Because C++ type Casting will not return you a nullptr if it fails and will crash on you if you try todo something with it.

You most likely dont get a AMyPlayerController there. Can you do a quick Log like that:

UE_LOG(LogTemp, Warning, TEXT("MyClass is %s : "), *NewPlayer->GetPathName());

Edit: Sry used the Protected Function :smiley: fixed now
