UAbilitySystemComponent::OnOwnerActorDestroyed

#include "AbilitySystemComponent.h"

Access: public Specifiers: UFUNCTION

Description

Internal callback bound to the owner actor's OnDestroyed delegate. Clears the OwnerActor pointer when the logical owner (e.g. a PlayerState) is destroyed.

Caveats & Gotchas

• Like OnAvatarActorDestroyed, do not call this manually — it is wired up by InitAbilityActorInfo and fires automatically through the engine's actor lifecycle.
• In most gameplay scenarios OwnerActor (PlayerState) outlives the Pawn, so this fires less often than OnAvatarActorDestroyed — but in session teardown it fires during world cleanup and ability tasks should tolerate null owners.

Example

Awareness of owner-destroyed timing in ability code C++

// In an ability task's OnDestroy, always guard against null owner:
void UMyAbilityTask::OnDestroy(bool bInOwnerFinished)
{
    if (UAbilitySystemComponent* ASC = AbilitySystemComponent.Get())
    {
        // Safe: ASC may still exist even if owner actor is gone
        ASC->ConsumeAllReplicatedData(AbilityHandle, PredictionKey);
    }
    Super::OnDestroy(bInOwnerFinished);
}
