UActorComponent::IsBeingDestroyed

function Engine Blueprint Since 4.0

#include "Components/ActorComponent.h"

Access: public Specifiers: UFUNCTIONBlueprintCallableconst

Description

Returns true if the component has begun its destruction sequence but has not yet been fully destroyed. Useful to guard against use-after-destroy in async or deferred callbacks.

Caveats & Gotchas

• This returns true from the moment BeginDestroy is entered through to garbage collection. If you hold a raw pointer to a component, this check is insufficient — prefer TWeakObjectPtr and IsValid() to detect pending destruction from external code.
• Components being destroyed will still tick until their owning actor's EndPlay completes, so a ticking component may return true from IsBeingDestroyed during its own TickComponent.

Example

Guard a delegate callback against destroyed components C++

MyTimerHandle = GetWorld()->GetTimerManager().SetTimerForNextTick([WeakComp = TWeakObjectPtr<UMyComponent>(this)]()
{
	if (WeakComp.IsValid() && !WeakComp->IsBeingDestroyed())
	{
		WeakComp->DoWork();
	}
});
