ScorllView problems

[wangzy_88]

1"Cancel Drag If Fits" is useless sometimes,Log show is float precision problem.

2 If use ScrollView+Grid,the first item can't click, change ScrollView+Table will fix it.
I use BoxCollider2D and UICamera's Event Type set "2D UI".UIDrag ScrollView and its BoxCollider2D is ScrollView's parent.3.7.x has no problem,now I use 3.9.0b.

Why ignore my post...

Because I don't understand what you posted.

Sorry for my bad english...

1"Cancel Drag If Fits" is for scrollview can't be filled with items solution,but sometimes scrollview still can drag one time,I print log show panel's clip in shouldMove param is different.For example,it's y may be 0.99999 or 1.00001.

2 If I use UIGrid,the first item can't click sometimes,change UITable will be ok.If can't click, change BoxCollider2D on item will fix it,seem like UIDrag ScrollView's collider cover item's collider.

Thank you very much.

1. I think I know this one... if I think of a good fix, I'll patch it on my end -- but you can suggest a fix if you have looked into it on your end.

2. UITable just positions children, it won't break the ability to click on something. If you are using 2D colliders, due to how Unity works it may not be possible to click on small 2D box colliders unless you get rid of UIRoot with its small scale (or just set UIRoot's size to 1).

1.Check position when items create,change it if deviation is small enough.

2.How to change UIRoot's size?I see it's scale will check on Update.

[ArenMook]

Change the UIRoot to be constrained and just set the height to 1.

Thx for reply,I change UIRoot scale but have no help.

I understand the second problem,it's because of the parent of scrollview which I add UIDragScrollView don't have a UIComponent,so NGUI can't handle it's collider's depth.
I decide to use collider3D and change it's center's Z to solve this problem.But I still don't understand why UITable is ok.

[ArenMook]

Use invisible widgets.

ALT+SHIFT+W.

[wangzy_88]

Thx,I will try.

[wangzy_88]

It's a very useful solution.
