UIButton multiple tween target on Color Change.

[yuewah]

I would suggest the following fix for updating other UIButton script color

1. [AddComponentMenu("NGUI/Interaction/Button")]
2. public class UIButton : UIButtonColor
3. {
4.  
5.         public bool isEnabled
6.         {
7.                 get
8.                 {
9.                         Collider col = collider;
10.                         return col && col.enabled;
11.                 }
12.                 set
13.                 {
14.                         Collider col = collider;
15.                         if (!col) return;
16.                        
17.                         if (col.enabled != value)
18.                         {
19.                                 col.enabled = value;
20.                                
21.                                 UIButton[] buttons = this.gameObject.GetComponentsInChildren<UIButton>();
22.                                 for (int i = 0; i < buttons.Length; ++i)
23.                         buttons[i].UpdateColor(value, false);
24.                         }
25.                 }
26.         }

ArenMook, could you add this to the release

[ArenMook]

No I can't. What if you have more than one button script in the hierarchy, and you don't want this behaviour? Forcing it is a bad idea.

[yuewah]

sorry, it should be in the same level

1.  
2.                 UIButton[] buttons = this.gameObject.GetComponents<UIButton>();
3.                 for (int i = 0; i < buttons.Length; ++i)
4.                         buttons[i].UpdateColor(value, false);
5.

That's more reasonable, but honestly if you need this kind of functionality you should just create a custom UIButton class for yourself.

Could somebody provide a working setup of such button?
Currently my button contains two overlapping sprites:

- UIButton with Collider
-- UISprite
-- UISprite

TweenTarget was set to the same GameObject with UIButton but is always automatically reset to None.
TweenColor doesn't work at all.

How should I rework my setup to make the button change color of each sprite it consists of?

[ArenMook]

UIButton's tween target should point to one of the sprites, not itself.

[imperso]

Yes, but my button consists of two overlapping sprites, and I need the button to change hover color of both of them, not just one. Is there any layout to this without creating custom UIButton class?

[ArenMook]

Just attach two UIButton scripts. One pointing to the first sprite, the other button pointing to the second sprite.

[imperso]

Thanks, I figured it out.
The problem is - my sprites overlap. So if I click the area of overlapping, my button technically fires twice.

EDIT: Overlapping is not the case - it seems that such button always fires twice.

EDIT2: Found some solution by adding UIButtonColor and pointing it to the second sprite (first one is already connected to the main UIButton).
Alas, it seems this component is deprecated (NGUI suggests me "to upgrade to a Button").

[ArenMook]

Button fires twice? Only one button script should have the event delegates set. Second should be used only for color changes.

[imperso]

Yep, eventually this was my mistake.
