물결 파동처럼 움직이는 오브젝트 만들기 & 좌우반전이동 | Wave Moving Object, Mathf.Sin | 유니티 게임 개발 튜토리얼(Unity & C# Script)

 

 

유령 오브젝트를 좌우반전(Object Flip Move) 이동 시키면서 물결치듯 움직이게 제어할 수 있습니다. 이동거리(Distance), 이동속도(Move Speed), 파동빈도(Wave Frequency), 파동높낮이(Wave Height)를 인스펙터 창에서 가능합니다. Mathf.Sin 메소드를 이용해 사인파 이동궤적을 만들 수 있습니다.

 

[Header("Title")] : 인스펙터창에 제목, 설명 문구 표시
[SerializeField] : Private변수를 인스펙터창에 노출
[Range(Min, Max)] : 범위지정 (Min, Max)
