[Drag Down] 기믹 액터 만들기(부드럽게 움직이기, 회전하기..)

Position을 원하는 만큼 추가하고 해당 위치를 순회하도록

그리고 X, Y, Z 회전을 넣고 싶다

 

그리고 블루프린트로 상속해서 스테틱 메시 설정 가능하도록 하자

BeginPlay -> ActGimmick -> MoveComponentTo -> OnActionFinished -> ActGimmick -> ...
계속해서 반복하도록 코드 작성

 

bIsEaseOut / In은 처음에 부드럽게 출발, 천천히 출발하는 설정

 

이런 식으로 Details에 설정 가능

 

 

이렇게 동작함

근데 MoveComponentTo는 최소 거리로 움직이니 회전 방향 설정을 원하면 90 -> 180 -> 270 -> 360 이런 식으로 설정하면 됨
