HP Progress Bar won't move when the character is attacked.

First, I did it with Initialize(), but there was a crash, so I made it with the existing code in NativeConstruct().

void UOLHpBarWidget::NativeConstruct()
{
	Super::NativeConstruct();

	// 해당 컨트롤을 이름으로 찾기
	HpBarProgress = Cast<UProgressBar>(GetWidgetFromName(TEXT("HpBar")));
	ensure(HpBarProgress);

	// CharacterBase의 함수 가져오기
	APawn* Player = GetOwningPlayerPawn();	// Player 가져오기
	ensure(Player);

	IOLHpInterface* PlayerInterface = Cast<IOLHpInterface>(Player);
	ensure(PlayerInterface);

	PlayerInterface->SettingHpBar(this);

	HpBarProgress->SetPercent(1.f);

	UpdateHpBar();
}

I put a value of 1.f in SetPercent. The reason is that the Hp Bar should have been full of green when the game started, but it’s gray.

void UOLHpBarWidget::UpdateHpBar()
{
	UE_LOG(LogTemp, Error, TEXT("Hp Loding..."));

	APawn* Player = GetOwningPlayerPawn();	// Player 가져오기
	ensure(Player);

	IOLHpInterface* PlayerInterface = Cast<IOLHpInterface>(Player);
	ensure(PlayerInterface);

	UpdateHp = PlayerInterface->SetHp();
	UE_LOG(LogTemp, Log, TEXT("UpdateHp: %f"), UpdateHp);

	if (HpBarProgress)
	{
		HpBarProgress->SetPercent(UpdateHp);
		UE_LOG(LogTemp, Error, TEXT("UpdateHp"));
	}
	else
	{
		UE_LOG(LogTemp, Error, TEXT("Nooooo HpBar"));
	}


}

So when I checked it in this code, UpdateHp was 0. For your information, the SetHp function returns. returnHp / MaxHp; returns this value. But I don’t understand why it comes out as 0…
