Title: UIGrid get most recent element added.
Post by: Genhain on May 13, 2014, 03:21:12 AM

I have inherited from UIGrid and i was wondering if there is a way to...when any element get's added there is perhaps a callback method that fires and also providing the element that was just added in the parameters? I know you could could just iterate through the children but that could end up requiring a lot of if statements to find out if it's the one you want.

Is there a method or functionality that allows this?

Cheers.

I Came up with a solution that requires quite a bit of extension on top of the NGUI classes, luckily most of them seem to be setup to allow this.

First i have my own base class

1. public class MyGrid : UIGrid
2. {
3.         // Use this for initialization
4.         protected override void Start()
5.         {
6.                 base.Start();
7.         }
8.        
9.         // Update is called once per frame
10.         protected override void Update ()
11.         {
12.                 base.Update();
13.         }
14.  
15.         public virtual void CardDroppedIntoGrid(GameObject gObject)
16.         {
17.  
18.         }
19. }
20.  

and I have a few other grid types that inherit from this and override CardDroppedIntoGrid.

Then I have an extension for UIDragDropItem

1. public class MyDragDropItemSelection : UIDragDropItem
2. {
3.         protected override void OnDragDropRelease (GameObject surface)
4.         {
5.                 base.OnDragDropRelease (surface);
6.  
7.                 //message grid
8.                 WCGrid grid =(WCGrid)mGrid;
9.                 grid.CardDroppedIntoGrid(gameObject);
10.         }
11. }
12.  

and that does the trick
