UIPopupList Help (How to execute function on value selection)

[Avagantamos]

Hello!  I tried reading through the NGUI documentation and past forum threads, but I can't seem to understand how to get UIPopupList to execute a function when a value is selected.  I can show you what I have tried:

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class ShamanBaseScript : MonoBehaviour {
5.  
6.  
7.         public UIPopupList popUP;
8.  
9.        
10.         void Update () {
11.  
12.                 if (popUP.value == "Add 1 Mana") {
13.                     transform.rotation = Quaternion.Euler (0, 0, -90);
14.                 }
15.  
16.                        
17.         }

All I'm trying to do is say: When you select the 'Add 1 Mana' option in the popup list turn the object -90 degrees.  I feel as though there is something I'm missing.  Past threads have spoken about OnSelectionChange(); and onChange  but I have no idea how to implement these.  I would really appreciate a simple example.  Thank you!

There are several ways to implement EventDelegate.  Here is the most common:

1. public UIPopupList popup = null;
2.  
3. void Start()
4. {
5.      EventDelegate.Add(popup.onChange, OnChange_Popup);//beware:   .Add or .Set
6. }
7.  
8. public void OnChange_Popup()
9. {
10.      print(popup.value);
11.      
12.      if (popup.value == "Add 1 Mana")
13.           transform.rotation = Quaternion.Euler (0, 0, -90);
14. }
15.
