터치시 탱크로 날아가는 유도탄(유도미사일) 구현 | 레이어간 충돌 예외 처리, 탱크 좌우반전이동, 폭발음발생, 미사일 파괴 Destroy, 애니메이션 프리팹 Instantiate

 

 

대전차 유도미사일 (Antitank Guided missile / Cruise Missile)

탱크 좌우 반전하면서 왕복 이동

미사일이 탱크와 충돌했을 때
- 폭발음 발생(OnTriggerEnter2D - PlayOneShot)
- 미사일 파괴(OnTriggerEnter2D - Destroy)
- 폭발 애니메이션 프리팹 생성 (Animation - Instantiate)

미사일끼리 충돌할 때 폭발하는 걸 방지하기 위해
Edit - Project Setting - Physics 2D
레이어간의 충돌 설정(충돌 예외 처리)
