            int damage = Random.Range(1, 3);
            Debug.Log("damage : " + damage);

            //現在のHPからダメージを引く
            currentHp = currentHp - damage;
            Debug.Log("After currentHp : " + currentHp);
            slider.value = (float)currentHp / (float)maxHp; ;
            Debug.Log("slider.value : " + slider.value);
        }
    }
}
                                                                                                                                                          

にAnimator is not playing an AnimatorControllerと出てきて困ってます。アニメーションが動かない状態です。直し方わかりますか？？
