On Actor Begin Overlap

Called when another actor begins to overlap this actor, for example a player walking into a trigger. For events when objects have a blocking collision, for example a player hitting a wall, see 'Hit' events.

On Actor End Overlap

Called when another actor stops overlapping this actor.

On Component Begin Overlap

Event called when something starts to overlaps this component, for example a player walking into a trigger. For events when objects have a blocking collision, for example a player hitting a wall, see 'Hit' events.
