[laurentl]

it's all offset for some reason:
structure is:
panel with draggable panel
grid
dragpanelcontents ...

it looks like this : https://www.youtube.com/watch?v=JVbhdG0CBv4

I'm using this script to center on click:

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class CenterOnObject : MonoBehaviour {
5.  
6.         public UIDraggablePanel dragPanel;
7.         void Start ()
8.         {
9.                 dragPanel = NGUITools.FindInParents<UIDraggablePanel> (gameObject);
10.         }
11.  
12.         void OnClick ()
13.         {
14.                 Center ();
15.         }
16.         public void Center ()
17.         {
18.                 if (dragPanel) {
19.                         Vector3 pos = dragPanel.transform.worldToLocalMatrix.MultiplyPoint3x4 (transform.position);
20.                         SpringPanel.Begin (dragPanel.gameObject, -pos, 7f);
21.                 }
22.         }
23. }
