(Unreal : 입문) 14. 소켓 실습

Posted by : Unreal at Sep 16, 2021

무기변경을 해보자

만약 왼손에 뭔가를 쥐게하고 싶다면 메쉬 -> 스켈레톤 트리 -> hand_l에 소켓을 추가하자

AMyCharacter::AMyCharacter()
{
 	// ...

    // 소켓을 찾고
	FName WeaponSocket(TEXT("hand_l_socket"));

    // 소켓이 있을경우
	if (GetMesh()->DoesSocketExist(WeaponSocket))
	{
        // Static Mesh에 붙여준다
		Weapon = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("WEAPON"));

		static ConstructorHelpers::FObjectFinder<UStaticMesh> SW(TEXT("StaticMesh'/Game/ParagonGreystone/FX/Meshes/Heroes/Greystone/SM_Greystone_Blade_01.SM_Greystone_Blade_01'"));
		if (SW.Succeeded())
		{
			Weapon->SetStaticMesh(SW.Object);
		}

		Weapon->SetupAttachment(GetMesh(), WeaponSocket);
	}
}

무기를 바닥에 두었다가 줍게 만들어보자

C++클래스로 MyWeapon 생성

UCLASS()
class TESTUNREALENGINE_API AMyWeapon : public AActor
{
	GENERATED_BODY()
	
public:	
	// Sets default values for this actor's properties
	AMyWeapon();

protected:
	// Called when the game starts or when spawned
	virtual void BeginPlay() override;

public:

	UPROPERTY(VisibleAnywhere)
	UStaticMeshComponent* Weapon;

};

AMyWeapon::AMyWeapon()
{
 	// 틱을 돌리지 않기에 false로 둔다
	PrimaryActorTick.bCanEverTick = false;
	
    // 나머지는 위와 동일
	Weapon = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("WEAPON"));

	static ConstructorHelpers::FObjectFinder<UStaticMesh> SW(TEXT("StaticMesh'/Game/ParagonGreystone/FX/Meshes/Heroes/Greystone/SM_Greystone_Blade_01.SM_Greystone_Blade_01'"));
	if (SW.Succeeded())
	{
		Weapon->SetStaticMesh(SW.Object);
	}

    // 충돌 컬리전 설정
	Weapon->SetCollisionProfileName(TEXT("NoCollision"));
}

void AMyCharacter::BeginPlay()
{
	Super::BeginPlay();

	FName WeaponSocket(TEXT("hand_l_socket"));

    // 무기 스폰
	auto CurrentWeapon = GetWorld()->SpawnActor<AMyWeapon>(FVector::ZeroVector, FRotator::ZeroRotator);

    // 무기 줍기
	if (CurrentWeapon)
	{
		CurrentWeapon->AttachToComponent(GetMesh(),
			FAttachmentTransformRules::SnapToTargetNotIncludingScale,
			WeaponSocket);
	}
}
