MissingComponentException: There is no 'Collider' attached to the "Player" game object, but a script is trying to access it.

You probably need to add a Collider to the game object "Player". Or your script needs to check if the component is attached before using it.

아예 "GetComponent<Collider>()" 메서드로 참고하지 말라는 댓글이 있어서 메서드를 지워보니 해결되었다.

3) 수정 완료 코드

if(collision.CompareTag ("Player")){

StartCoroutine (fall ());

}
