AActor::OnActorEndOverlap

property Engine Blueprint Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: UPROPERTYBlueprintAssignable

Description

Multicast delegate fired when another actor stops overlapping this actor. Pair with OnActorBeginOverlap to track when actors enter and exit an overlap region.

Caveats & Gotchas

• Like OnActorBeginOverlap, both actors must have bGenerateOverlapEvents enabled for this to fire. If only the begin event fires but end never does, check the other actor's overlap settings.
• EndOverlap is also called when either actor is destroyed while still overlapping — handle the case where OtherActor may be pending kill by checking IsValid(OtherActor) at the start of the handler.
• When an actor is teleported rather than moved continuously, the engine may not always generate matching Begin/End pairs; test sweep-based teleports carefully.

Examples

Show an actor again when the player leaves the overlap zone Blueprint

Bind end-overlap to reset a trigger C++

void AMyTrigger::BeginPlay()
{
	Super::BeginPlay();
	OnActorEndOverlap.AddDynamic(this, &AMyTrigger::HandleOverlapEnd);
}

void AMyTrigger::HandleOverlapEnd(AActor* OverlappedActor, AActor* OtherActor)
{
	if (IsValid(OtherActor))
	{
		UE_LOG(LogTemp, Log, TEXT("%s left trigger"), *OtherActor->GetName());
	}
}
