[Auran131 (Auran13)]

use a manager class, lets say GameState

pseudo code

1. On actor begin play GetGameState->AddActor(self)
2. Constuct the widget, on event Construct GetGameState->BindToActorAdded(Actor)
3. OnAddActored Event, pass through Actor, OnWidgetHovered Actor->CallHightlightActor
4. Any other info cant be gotten from the Actor (Cast/Interface)
