Validation causes Crash

Development Programming & Scripting
1

Working with pointers in Unreal, I quickly got into the habit of validating them before using them. In a project with lots of spawned and deleted Actors the validation itself crashes my game. How would I resolve this?

TArray<AActor*> SpawnedActors = {...};
	
for (size_t i = 0; i < SpawnedActors.Num(); i++)
{
	//Valid?
	if (!SpawnedActors[i]) continue;
	if (!SpawnedActors[i]->IsValidLowLevel()) continue;
	if (!IsValid(SpawnedActors[i])) continue;		// <-- This sometimes causes a crash!
	if (SpawnedActors[i]->IsPendingKill()) continue;
	if (SpawnedActors[i]->IsActorBeingDestroyed()) continue;
}

Thank you and best regards,
Simon

I’ve added UPROPERTY() to the variable.I’ll mark this as answered if further testing shows that the crash is gone.
