Title: 3.5.7 UIButton possible bug? : 'normal color' is set by a UIWidget's alpha.
Post by: briangibson on April 24, 2014, 01:13:50 AM

UIButton's 'Normal Color' is coupled to the UIWidget's 'alpha' property.
This means that if I do a TweenAlpha on a UIWidget that has a button on it, it uses whatever the color that was set before I hit play.
This is counterintuitive and seems an awful lot like a bug- but perhaps the suggested workaround is to not have a UIWidget and a UIButton on the same gameobject?

I.e.: there are two possible scenarios, and each behaves differently:
1) I set the Alpha property of the widget to 0, and hit play.
Run a TweenAlpha from code to trigger to a value of 1.
Hover over the button, and then hover away - the button will fade away to invisible.

2) I set the Alpha property of the widget to 1, and hit play.
Run a TweenAlpha from code to trigger a tween from 0 to a value of 1.
Hover over the button, hover away, nothing happens. this is to be expected.

Alpha is cumulative. If you want to tween alpha of something that also has its color tweened, then decouple them into a parent-child like so:

Widget (TweenAlpha)
- Sprite (TweenColor)
