Ticking refers to how Actors are updated in Unreal Engine. All Actors have the ability to be ticked each frame, or at a minimum, user-defined interval, allowing you to perform any update calculations or actions that are necessary. Actors all have the ability to be ticked by default via the Tick()function. If walking up the "owner chain" does not end at a PlayerPawn/PlayerController that belongs to a client, then the actor is not owned by any client.)
