NGUI : Cannot change NGUI Button sprite at Runtime when Pressing it.

Hello everyone,

I am actually stuck on something that should be quite simple but I cannot find any solution.

I am using NGUI, I have a GameObject named "Button - Sound" having UISprite, UIButton, properly set Box Collider on it. "sound_on_button" and "sound_off_button" are on the same UIAtlas.

The following script is attached to the GameObject :

Code (CSharp):

1. [RequireComponent (typeof (UISprite))]
2. public class B_Sound : MonoBehaviour {
3.  
4.     private UISprite S_Sprite;
5.     bool cheat = false;
6.  
7. void Start ()
8. {
9.         S_Sprite = gameObject.GetComponent<UISprite>();
10.         S_Sprite.spriteName = (cheat) ? "sound_on_button" : "sound_off_button";
11. }
12.    
13. void OnPress (bool isPressed)
14. {      
15.     if (enabled && !isPressed)
16.     {
17.             cheat = !cheat;
18.             S_Sprite.spriteName = (cheat) ? "sound_on_button" : "sound_off_button";
19.        }  
20. }
21.  
22.     #region Debug
23.     #if UNITY_EDITOR || UNITY_REMOTE
24.     void Update()
25.     {
26.         if (Input.GetKeyUp("e"))
27.         {
28.             cheat = !cheat;
29.             S_Sprite.spriteName = (cheat) ? "sound_on_button" : "sound_off_button";
30.         }
31.     }
32.     #endif
33.     #endregion
34. }

The button Sprite is set on Start and GetKeyUp operations but not with OnPress (or sometimes when I click repeatedly on the Editor).

I hope you will have some clue for me, I am stuck on this for hours :/
Thanks in advance

 

Finally got it fixed ... I don't know why but manage to make it working using :

Code (CSharp):

1. gameObject.GetComponent<UIButton>().normalSprite

Hope it will be useful for someone.
