UPROPERTY(VisibleAnywhere) : 프로퍼티 디테일 창에 보이도록 설정

UPROPERTY(EditAnywhere, Category=ID) : 수정도 가능하도록 설정, 프로퍼티 카테고리도 지정

UPROPERTY(EditAnywhere, Category = Stat, Meta = (AllowPrivateAccess = true)) : Private 속성이지만 디테일창에 보이고 수정도 가능하도록 설정

해당 컴포넌트 초기화

Body = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("BODY"));

해당 컴포넌트를 루트 컴포넌트로 지정.

RootComponent = Body;

현재 클래스의 하위에 해당 컴포넌트 배치함.

Water->SetupAttachment(Body);

해당 컴포넌트의 시작 위치를 지정.

Water->SetRelativeLocation(FVector(0.0f, 0.0f, 135.0f));
