Why does TickComponent fire after the actor is destroyed?

Destruction happens at end of frame; tick may already be queued. Set PrimaryComponentTick.bCanEverTick = false in EndPlay to remove from the tick group, or guard the tick body with IsValid(GetOwner()).

What's IsPendingKill in UE5?

Replaced with IsValid() / IsValidLowLevel(). UE5 uses MarkAsGarbage instead of MarkPendingKill. Use IsValid for both cases. Always validate before dereferencing UObjects in async or tick code.

Should I set tick to false in BeginDestroy?

EndPlay is the right place. BeginDestroy is GC; too late for tick management. EndPlay fires when the actor is removed from the world (destroy or level transition).

Fix: Unreal Actor Component Tick After Destroy Warning

Quick answer: In EndPlay, set PrimaryComponentTick.bCanEverTick = false and SetComponentTickEnabled(false). Guard tick body with IsValid(GetOwner()). Stops the warning and prevents stale-actor crashes.

Console: “TickComponent called on a component pending kill.” Component still ticking after the owning actor was destroyed.

The Symptom

Warning logs at gameplay end. Sometimes a crash if the tick body dereferences members of the now-disposed actor.

The Fix

void UMyComponent::EndPlay(const EEndPlayReason::Type EndPlayReason)
{
    PrimaryComponentTick.bCanEverTick = false;
    SetComponentTickEnabled(false);
    Super::EndPlay(EndPlayReason);
}

void UMyComponent::TickComponent(float dt, ELevelTick TickType, FActorComponentTickFunction* TickFunc)
{
    Super::TickComponent(dt, TickType, TickFunc);
    if (!IsValid(GetOwner())) return;

    // safe to access owner
}

Disable tick on EndPlay and guard the body. Tick removes itself from the tick groups; even if a queued tick lands, the guard catches it.

Async Code

For async tasks (HTTP, latent BP nodes) that hold a component reference, use TWeakObjectPtr in the lambda capture and validate before dereferencing. See related post.

Verifying

Destroy actors mid-tick. No more warnings. Profile shows tick count drops as actors leave.

“Disable tick in EndPlay. Validate owner. No stale ticks.”
