[Unity 2D / 유니티 교과서] 6장 예제 ClimbCloud

Rigidbody : 중력, 마찰 힘 계산 (강체)

 -물리 영향을 무시 : Body Type - Kinematic (기본 Dynamic)

 -회전을 방지 : Constraints - Freeze Rotation z활성

 

Collider : 충돌 판정

OnTriggerEnter2D(Colider2D) : 

 

SceneManager

 

자주 사용하게 될 Find method

 -복수형에 주의! 단수형은 처음 찾은 대상을 반환, 복수형은 배열을 반환

• FindGameObjectsWithTag(태그이름)
• FindObjectsOfType(타입이름)
