GetActorForwardVector() missing

Hello everyone!
I’m quite new to Unreal engine, I was following some tutorials on how to make a character with c++ when I encountered this problem:
the function GetActorForwardVector() in my custom character class doesnt seem to exist.


Sorry for my bad english.
Thank you for your answers.

You are missing the scope resolution for the method:

AMyActor::Forward(float dir) {}
