        Move();


    }
    private void Move()
    {

        float _moveDirX = Input.GetAxisRaw("Horizontal");
        float _moveDirZ = Input.GetAxisRaw("Vertical");

        Vector3 _moveHorizontal = transform.right * _moveDirX;
        Vector3 _moveVertical = transform.forward * _moveDirZ;

        Vector3 _velocity = (_moveHorizontal + _moveVertical).normalized * walkSpeed;
        myRigid.MovePosition(transform.position + _velocity * Time.deltaTime);
    }

}

이렇게 작성했는데 MissingComponentException: There is no 'Rigidbody' attached to the "Player" game object, but a script is trying to access it. 오류가 나요 뭐가문제죠?
