QUESTION
It crashes anytime I'm trying to change SpringArmComponent->TargetArmLength
,
even if I do this: UE_LOG(LogTemp, Warning, TEXT("%f"), SpringArmComponent->TargetArmLength);
What am I doing wrong?
It crashes in the ZoomIn()
and ZoomOut()
functions, but it works in the constructor. If I do only SpringArmComponent->TargetArmLength
it won't crash, but it does if I try to log it.

If so I've noticed that this can cause issues with component creation and will cause the engine to crash and return NULL for the component that is otherwise being set up properly.
I would suggest maybe trying to create a new derived class and see if that works. I know it's a strange suggestion but it worked for me.
