Hello everyone!

I need to execute delayed fuction with parameters, but can’t understand how can I do it
I tried some ways that I found on old forumsm but it doesn.t work =(

Params

  1. UAnimMontage* FireAnim,
  2. FRotator FireDirection,
  3. const TArray>& Query,
  4. float Damage

Which way can I pass this parameters to timer?

Figured it out with lambda

void APlatformerCharacter::FireReq_Implementation(UAnimMontage* FireAnim, FRotator FireDirection, const TArray<TEnumAsByte<EObjectTypeQuery>>& Query, float Damage)
{
	Fire(FireAnim, FireDirection, Query, Damage);

	GetWorldTimerManager().ClearTimer(FirePreDelay);
	TimerDelegate.BindLambda([&, FireAnim, FireDirection, Query, Damage]()
	{
		if (HasAuthority())
		{
			FVector StartTrace = GetCapsuleComponent()->GetComponentLocation();
			FVector EndTrace = GetCapsuleComponent()->GetComponentLocation() + (FireDirection.Vector() * 200.f);
			FHitResult HitRes;
			TArray<AActor*> Empty;

			UKismetSystemLibrary::LineTraceSingleForObjects(
				GetWorld(),
				StartTrace,
				EndTrace,
				Query,
				false,
				Empty,
				EDrawDebugTrace::ForDuration,
				HitRes,
				true,
				FLinearColor::Red,
				FLinearColor::Green,
				5.f
			);

			AP_DestructBlock* DestrBlock = Cast<AP_DestructBlock>(HitRes.Actor);
			if (DestrBlock)
			{
				DestrBlock->AddDamage(Damage, DestrBlock);
				if (DestrBlock->DMI)
				{
					float NewHealthVal = DestrBlock->CurrentHealth - Damage;
					DestrBlock->SetCurrentHealth(NewHealthVal);
					DestrBlock->OnRep_CurrentHealth();
				}
			}
		}
	});

	if (CurrentWeapon)
	{
		GetWorldTimerManager().SetTimer(FirePreDelay, TimerDelegate, CurrentWeapon->PreFireDelay, false);
	}
