FTimerDelegate with arguments dosnt work

Unreal Engine Programming & Scripting C++
#1

Hello, good morning. I`m trying to do a Destroy() on OtherActor in a OnHit function after certain time. Basically I added some impulse to the Actor I hit, and I want to destroy it few seconds after.

I`m trying to use “FTimerDelegate”, using this syntax:
in the header file:


UFUNCTION()
void DestroyOtherActor(AActor* ActorToDestroy);

FTimerHandle DestroyActorHandle;
FTimerDelegate DestroyActorHandleDelegate;

In cpp file I tried with this syntax:

I`m trying to do inside the OnHit function, which is this:


void ABulletProjectile::OnHit(UPrimitiveComponent * HitComp, AActor * OtherActor, UPrimitiveComponent * OtherComp, FVector NormalImpulse, const FHitResult & Hit)
{

    FTimerDelegate DestroyActorHandleDelegate;

    DestroyActorHandleDelegate.BindUFunction(this, FName("DestroyOtherActor"), OtherActor);
    GetWorldTimerManager().SetTimer(DestroyActorHandle, DestroyActorHandleDelegate, 0.2f, false, 0.2f);
}

and this syntax:


FTimerDelegate RespawnDelegate = FTimerDelegate::CreateUObject(this, &ABulletProjectile::DestroyOtherActor, OtherActor);
GetWorldTimerManager().SetTimer(DestroyActorHandle, RespawnDelegate, 0.2f, false, 0.2f);

and this is the function to call:


void ABulletProjectile::DestroyOtherActor(AActor* ActorToDestroy)
{
FVector OtherActorLocation = ActorToDestroy->GetActorLocation();
UGameplayStatics::SpawnEmitterAtLocation(this, KilledEnemyParticle, OtherActorLocation);
ActorToDestroy->Destroy();
}

but neither seem to work. I dont see any errors in the editor, nor warnings.

Thanks
