unity，遇到问题，我在做愤怒的小鸟，实在不知道怎么办

           ** birds[i].transform.position = originPos;
            birds[i].enabled = true;
            birds[i].sp.enabed = true;
            birds[i].canMove = true;
        }
        else
        {
            birds[i].enabled = false;
            birds[i].sp.enabled = false;
            birds[i].canMove = false;
        }
    }
}

public void NextBird() ... }

问题：

}

你这一堆错，第一个报错可能是你的bird类的sp定义成private类型了，第二个canMove要么也是定义成private类型，要么就没写。。。。。。
