SpringBoard is stopping when Start()

[Prin_E]

Hi,
I'm using NGUI 3.5.3 (updated today 

I placed scroll view on my panel and referenced by my simple script.
and I added UICenterOnChild component on scroll view.

I wrote...

void Start() {
    // .... scroll view item creation...
   centerOnChild.CenterOn(center_item);
}

like this.

but, scroll view couldn't actually move item center.
I checked game object, and i found that spring board is disabled. 
After some debugging, I found the reason...

when UIScrollView's first update, it disables spring board itself... This is strange 
actually, I solved this problem with moving instantiated all items directly (transform.localPosition += offset for each)..
but I hope re-enabling spring is called after first update in next version.

Thank you!

UICenterOnChild performs the Recenter() when it's enabled. UIScrollView doesn't do anything when it starts up, and it has no Update() function.

Hmm...

UICenterOnChild seems to be working correctly. It adds SpringPanel components on scroll view.

I think the problem is anchor.

I activated Anchor on my scroll view.

On anchoring, UIScrollView.SetDragAmount() is called, and SetDragAmount() disables current spring panel.

The scroll view activates SpringPanel.Begin only from one place -- RestrictWithinBounds function, line 376 of UIScrollView. What's the call stack for you, where is it being called from?

[Prin_E]

UIScrollView.DisableSpring()
UIScrollView.SetDragAmount()
UIScrollView.UpdatePosition()
UIPanel.set_baseClipRegion
UIPanel.OnAnchor()
URect.Update()

I see. Well, delay your CenterOn call until the end of frame, and you should avoid this conflict.
