(Unreal : 입문) 16. 스탯 매니저

Posted by : Unreal at Sep 16, 2021

체력바를 표시해보자

전역으로 사용할 변수를 지정할 수 있는 GameInstance C++ 클래스를 생성

USTRUCT()
struct FMyCharacterData : public FTableRowBase
{
	GENERATED_BODY()

	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	int32 Level;

	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	int32 Attack;

	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	int32 MaxHp;
};

위에서 만든 FMyCharacterData는 아래와 같이 실제로 볼 수 있다

/**
 * 
 */
UCLASS()
class TESTUNREALENGINE_API UMyGameInstance : public UGameInstance
{
	GENERATED_BODY()

public:
	UMyGameInstance();

	virtual void Init() override;

	FMyCharacterData* GetStatData(int32 Level);

private:
	UPROPERTY()
	class UDataTable* MyStats;
};

UMyGameInstance::UMyGameInstance()
{
	static ConstructorHelpers::FObjectFinder<UDataTable> DATA(TEXT("DataTable'/Game/Data/StatTable.StatTable'"));
	
	MyStats = DATA.Object;
}

void UMyGameInstance::Init()
{
	Super::Init();

	UE_LOG(LogTemp, Warning, TEXT("MyGameInstance %d"), GetStatData(1)->Attack);
}

FMyCharacterData* UMyGameInstance::GetStatData(int32 Level)
{
	return MyStats->FindRow<FMyCharacterData>(*FString::FromInt(Level), TEXT(""));
}

게임의 인스턴스도 변경해야 줘야 동작한다

데미지 처리는 이렇게 하자

void AMyCharacter::AttackCheck()
{
	// ...


	if (bResult && HitResult.Actor.IsValid())
	{
		UE_LOG(LogTemp, Log, TEXT("Hit Actor : %s"), *HitResult.Actor->GetName());

		FDamageEvent DamageEvent;
		HitResult.Actor->TakeDamage(Stat->GetAttack(), DamageEvent, GetController(), this);
	}
}
