UActorComponent::IsPreUnregistering

function Engine Since 5.0

#include "Components/ActorComponent.h"

Access: public Specifiers: inline

Description

Returns true while this component is transitioning through the pre-unregistering phase — `UnregisterComponent` has been initiated but render and physics teardown has not yet completed.

Caveats & Gotchas

• During this state, the component's render proxy may still be alive. Do not assume any rendering resources have been released just because this returns true.
• Callbacks like `OnUnregister` are called during this state — accessing world subsystems from those callbacks is safe, but the component should be considered functionally deactivated.

bool

Example

Guard teardown code against double-unregister C++

void UMyComponent::BeginCleanup()
{
    if (IsPreUnregistering() || !IsRegistered())
    {
        return;  // Already tearing down
    }
    UnregisterComponent();
}
