event hit only works if both object’s collision settings are set to block each other. if one or both of them are set to overlap, then it calls an overlap event instead.
so instead of event hit, use an overlap event, and it will give you an actor reference that you can cast to the wall type. or instead of casting, you can check if the actor has a tag, or you can call an interface function on the actor that returns a boolean if the actor is sticky.
