Object Instantiated inside GridObjectCollection of ScrollingObjectCollection with opposite rotation

[tranquanglam123]

Describe the bug

I created a ScrollingObjectCollection name LeftScroll, it is a child of a gameobject name QSB which has SolverHandler to track the user's head.

LeftScroll has a GridObjectCollection inside the container, I scripted for the item to spawn inside the GridObjectCollection with the rotation of (0,0,0).

But in run time, whenever i turn around, the QSB's rotation changes so it can follow me, then the item spawned with the opposite rotation of the QSB ( for instance QSB (-5,30,0) -> item (5,-30,0)

##Steps to reproduce the behavior:

1. Create an object with solver handle to track the head
2. Create a child with scrollingobjectcollection -> gridobjectcollection inside container
3. Attached this script section inside the parent object and assign any object to be the item
   "for (int i = 0; i < ItemsPerPage; i++)
   {
   ItemBox tmpBox = Instantiate(SpawnItemBox);
   tmpBox.name = Manager.dataMachine[Manager.selectMachine].objectData[i].Name;
   tmpBox.SetIconName(tmpBox.name);
   tmpBox.transform.SetParent(ItemSlots);
   tmpBox.SetQuadIcon(Manager.dataMachine[Manager.selectMachine].objectData[i].smallicon);
   tmpBox.index = Manager.dataMachine[Manager.selectMachine].objectData[i].ID;
   Debug.Log("item id:" + tmpBox.index);
   tmpBox.transform.rotation = Quaternion.Euler(Vector3.zero);
   tmpBox.transform.localScale = new Vector3(1, 1, 1);
   ItemBoxes.Add(tmpBox);
   }
   StartCoroutine(InvokeUpdateCollection(griditem,scrollitem));
   Debug.Log("Grid Updated");"}
   private IEnumerator InvokeUpdateCollection(GridObjectCollection temp,ScrollingObjectCollection temp2)
   {
   yield return null;
   temp.UpdateCollection();
   yield return null;
   temp2.UpdateContent();
   }"
4. Run and see error

Expected behavior

Items spawned with rotation of (0,0,0) despite whatever direction the user's head.

The solution is actually simple, instead of using the prop "rotation", just use the "localRotation"

Explaination
"rotation" is the absolute rotation of the object in the scene while the "localRotation" is relative to its parent, so set it to 0,0,0, the component should be aligned with its parent.
