Parent of RectTransform is being set with parent property. Consider using the SetParent method instead, with the worldPositionStays argument set to false. This will retain local orientation and scale rather than world orientation and scale, which can prevent common UI scaling issues.

 public void Return(GameObject obj, Action<GameObject> action = null)
 {
     pool.Enqueue(obj); //풀안으로 새로운 오브젝트가 들어감.
     obj.transform.parent = parentTransform;
     //obj.transform.parent.SetParent(parentTransform, false); //이거는 오류가나타남
     //obj.transform.parent.SetParent(parentTransform, true); //true이든 false이든.. 오류발생
     obj.SetActive(false);   
     if(action != null)
     {
         action?.Invoke(obj);
     }
 }

transform의 parent 속성대신에 SetParent 를 쓰라고 경고메세지가 나타나는데요

근데 /obj.transform.parent.SetParent(parentTransform, false)
이런식으로 사용했더니, HIT_TEXT가 풀로 반환되면서 부모인 Layer1도 같이 반환되어서

UnityException: Transform child out of bounds Base_Canvas.Holder_Layer (System.Int32 value) (at Assets/00_Scripts/Base_Canvas.cs:28) HIT_TEXT.Init (UnityEngine.Vector3 pos, System.Double dmg, System.Boolean Critical) (at Assets/00_Scripts/HIT_TEXT.cs:76) Monster+<>c__DisplayClass6_0.<GetDamage>b__0 (UnityEngine.GameObject value) (at Assets/00_Scripts/Monster.cs:113) Object_Pool.Get (System.Action1[T] action) (at Assets/00_Scripts/Mng/Pool_Mng.cs:58) Monster.GetDamage (System.Double dmg) (at Assets/00_Scripts/Monster.cs:111) Bullet.Update () (at Assets/00_Scripts/Bullet.cs:83)
-------------------------------
Layers의 자식이 Layer3밖에 남지않아서
Base_Canvas 스크립트의
public Transform Holder_Layer(int value)

{

return LAYER.GetChild(value);
함수 호출시에 에러가 나더라구요

결국에는 그냥 transform.parent = parentTransform.
로 사용하고있는데 SetParent를 사용하라고 계속 경고메세지가 뜹니다. ㅠㅠ

SetParent(parentTransform, ture) 이던, false이던 Canvas>Layer1>HitText, 에서 Pool로 반환될때 Layer1도 같이 반환됩니다.
Layer0>"COIN_PARENT"도 마찬가지로 Layer0도 같이 반환됩니다.

그냥 경고메세지를 띄울수밖에없는건가요?
