[Unreal, VR] Custom VR Pawn Blueprint

 

우선 기본 vr pawn을 복제해준다.

복제한 My_VRPawn에다 여러가지 vr 플레이어 기능들을 커스텀해서 반영하기 위함이다.

 

! 부모 클래스를 캐릭터형으로 바꾸어준다!

 

기본 값

왼쪽, 오른쪽 엄지 조이스틱으로 이동, 회전

 

왼쪽 엄지 조이스틱으로는 이동을 결정하게 해준다.

get right vector

get forward vector

오른쪽 엄지 조이스틱으로는 회전을 담당하게 설정해준다.

 

 

 

위의 panw 구조를 직접 캐릭터 c++로 작성하고 싶다면 아래의 기본 틀을 가져가야 한다. VR Origin 구조를 캡슐 컴포넌트 아래에 만들어주고, 카메라와 왼손 오른손 컨트롤러를 그 아래에다가 계층이동 시켜주는 것이 핵심이다.
