[Unity/유니티] 유니티 오브젝트 합치기 (merge objects)

 

◆ 필요한 기능

오브젝트 a 와 b 를 합쳐 c 를 만드는 기능 (a 와 b 는 합치면 소멸됨)

 

 

 

기본 규칙

단계	오브젝트
1	All_0
2	All_1
3	All_2
...	...

 

리소스

오브젝트

Rigidbody2D, Collider2D 추가

- 카메라 화면 내에서만 조합할 경우, 중력값 0 으로 변경하여 화면에서 떨어지지 않도록 함

- Collider 추가 하지 않으면 아래 스크립트 작동하지 않음

- Collider 내에 Is Trigger 값 체크표시하여 허용 해야함
