콜라이더 2D(Collider 2D) 컴포넌트는 물리적 충돌을 위해 2D 게임 오브젝트의 모양을 정의합니다. 보이지 않는 콜라이더는 게임 오브젝트의 메시와 완전히 똑같을 필요는 없습니다. 사실 대략적인 근사치는 게임플레이에서 더 효율적이고 구별할 수 없는 경우가 많습니다.
2D 게임 오브젝트를 위한 콜라이더는 모두 이름이 “2D”로 끝납니다. “2D”로 이름이 끝나지 않는 콜라이더는 3D 게임 오브젝트에 사용됩니다. 3D 게임 오브젝트와 2D 콜라이더 또는 2D 게임 오브젝트와 3D 콜라이더를 혼합할 수 없습니다.
리지드바디 2D와 함께 사용할 수 있는 콜라이더 2D 타입은 다음과 같습니다.
리지드바디 2D 컴포넌트에서 자동 질량 사용(Use Auto Mass) 체크박스를 체크하여 자동으로 리지드바디 2D의 질량을 콜라이더 2D의 질량과 동일한 값으로 설정해야 합니다. 이 작업은 특히 부력 이펙터 2D와 함께 사용할 때 유용합니다.
