I would just try to delete and rebuild the get owner and cast to nodes. Otherwise, maybe your owning actor got reparented to a new class type (actor, or character, etc)?
ok I tried before (rebuild the get owner and cast to nodes) it doesn’t work
and about the parent class or child, how to check that?
tell me where should I go to answer you.
Seems like BP_Anim_Cannon isn’t Pawn or Character class (probably it is simple actor). To use “TryGetPawnOwner” your cannon should be pawn or character.
To check parent of given blueprint, open it and there is info in the upper right corner.
