Getting the "next" rotation of AddControllerYawInput

Heya,

As previously asked in this forum thread, I’m trying to get what the resulting rotation of “AddControllerYawInput” is going to be. I’ve looked at the source, but then I seemed to have issues getting the InputYawScale from within my ACharacter, or rather, getting the proper controller. Can I just cast the Controller property to a APlayerController? Thanks in advance.

Best regards,
Damir H.
