블루프린트 클래스

* CPP to BluePrint

 

BUT) BP는 CPP보다 10배 느리므로 남발하지 마라.

BP사용 => 주로 프로토타입

CPP사용 => 성능중요한 곳

변수명, 함수명은 거의 그대로 -> 그대로 찾아서 연결해주면 된다

 

- GameMode에서 기본Pawn을 BP캐릭터로 바꿔준다.

//기본생성자
AMyGameModeBase::AMyGameModeBase()
{
	//DefaultPawnClass = AMyCharacter::StaticClass();

	//FClassFinder생성자(찾을클래스)
	static ConstructorHelpers::FClassFinder<ACharacter>
		BP_Char(TEXT("Blueprint'/Game/BluePrints/BP_MyCharacter.BP_MyCharacter_C'"));

	if (BP_Char.Succeeded())
		DefaultPawnClass = BP_Char.Class;


}

BP는 경로뒤에_C를 써야함.(규칙임)

 

 

* BP_MyCharacter2 상속 MyCharater, BP_MyGameMode

내가 만든 클래스도 상속가능함.

CPP파일 : UI에서 Mesh변경=> (-) 1회용임. 계속적용X

vs

BP : CPP로 클래스를 만드는 것과 같음 =>  : UI에서 Mesh변경=>  계속적용(O)

 

- BP로 게임모드 만들기

(+) : GameMode는 자주변경됨 -> BP로 만들면 편리하게 변경가능.

월드세팅에서 BP_GameMode로 설정.
