reset a GameObject parents childs to 0 if a item has changed its parent
I'm working Right now on a game where someone else has programmed an inventory System with this tutorial: Klick
My Problem Right now is, if I drag an item into another Slot of the inventory, it's getting set to the other Slot as a child but the old Slot is also having still a child so the childcount is bigger than 0.
using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;
public class Slot : MonoBehaviour, IDropHandler
{
public GameObject item
{
get
{
if (DragHandeler.oldParent.GetChild(0).gameObject != DragHandeler.itemBeingDragged)
{
Debug.Log("2 tf: " + transform.childCount);
return transform.GetChild(0).gameObject;
}
else if (transform.childCount > 0)
{
Debug.Log("1 tf: " + transform.childCount);
return transform.GetChild(0).gameObject;
}
Debug.Log("get item else");
return null;
}
}
#region IDropHandler implementation
public void OnDrop(PointerEventData eventData)
{
if (!item)
{
DragHandeler.itemBeingDragged.transform.SetParent(transform);
//ExecuteEvents.ExecuteHierarchy<IHasChanged>(gameObject, null, (x, y) => x.HasChanged());
Debug.Log("Innerhalb: " + transform.childCount);
}
Debug.Log("Außerhalb: " + transform.childCount);
}
#endregion
}
I hope someone can help me with this one. I'm working in Unity 2017.2
Got the solution: I needed to add a Panel as parent from the Slots. Somehow it works then.
Have you tried with deleting the child object as soon as it gets dragged out of the slot and get put to antoher Slot? because then you would have a child count of 0 after its dropped onto antoher slot.
Doesn't work. If i destroy the GameObject (child) it will be destroyed even if it's on the new parent. I even tried to use transform.DetachChildren(); but this doesn't work either.
