I’m having a problem with animating a ScrollRect GameObject. I have 2 simple animations - FadeIn and FadeOut - that smoothly change a GameObject’s RectTransform’s localScale from zero to one and vice versa. I have a parent object to which I apply the Fade animations, and that parent also holds a child GameObject that uses a scroll rect, image, and mask. Like any other scroll rect, the child also has children that makes up the content of the scroll view window.
When I apply the animations to the top most parent object, the scroll view window seems to scroll by itself a little bit. To clarify:
A scroll rect window with a vertical slider bar before any animations have been played. The scroll view window is restricted so that it can only scroll vertically.
The same window after a single FadeOut → FadeIn cycle.
Repeating the Fade cycle has the same effect; the scroll rect scrolls down by a little bit after each cycle.
Even stranger, the window only sometimes scrolls down*.* Other times it stays in the exact same position like you’d expect, which makes the problem all the more frustrating.
After a little bit more testing, it seems like it’s the FadeOut animation specifically that shifts the scroll rect down, but I still have no clue why it has this behavior. I’ve tried every kind of anchor possible, but nothing I change there seems to have any effect on the problem.
Have I stumbled upon a bug about ScrollRects and animations involving scales? or have I done something horribly wrong? Any help is greatly appreciated.
