ThirdPersonPlayer 분석하기

ThirdPersonPlayer를 포함하고 프로젝트를 만들면 프로젝트명+Character.cpp가 만들어지고 이게 ThirdPersonCharacter 폴더의 BP_ThirdPersonCharacter의 부모 클래스 이다.

일단은 MyPlayer 클래스를 만들고 프로젝트명+Character의 내용을 복붙했다. 다음에는 프로젝트명+Character를 직접 변경가능한지 테스트 해보고 싶다.

MyCharacter클래스를 부모로 BP_MyCharacter로 만들고 GameMode에서 DefaultPawn으로 지정하고 플레이 해보니 뭔가 다르다 떠 있고 이동시 캐릭터의 방향이 다르다 오른쪽이 새로만든 MyPlayer이다 BP_MyCharacter에 AmimClass와 Mesh에 SK_Mannequin을 지정해줬다 클래스에서는 지정하지 않아 블루프린트에서 지정해줘야한다.

클래스는 똑같이 복붙했으니 BP_ThirdPersonCharacter와 BP_MyCharacter의 차이라고 생각하고 둘을 비교해 보자 최상단 root컴포넌트를 선택하고 Detail을 비교하자

일단 메시컴포넌트의 Rotation이 다르다 그래서 이동시 방향이 달랐다 이걸 수정해준다. Z Loction위치도 -90으로 변경

애니메이션이 없으니 맞춰주자. 비교를 위해 난 남자를 선택하였다.

Input설정을 똑같이 맞춘다. EnhancedInput인데 새로 만들것 없이 미리 만들어 놓은걸 사용한다. 여기까지 하면 바닥에 잘 붙어 다닌다.

Navigation이 약간 달랐다. 이거 아직 필요는 없는것 같다
