NGUI 3 Support / UICamera Lateupdate change

« on: September 07, 2016, 08:08:50 PM »

Hello again,

We are trying out a change to UICamer Lateupdate.  We want to move the UIRoot.Broadcast("UpdateAnchors"); statement to after the onScreenResize(); call (line 1736ish).

This is changing the order of onScreenResize and UpdateAnchors. Previously, it called UpdateAnchors first then call onScreenResize. This could cause a problem if there are some UI Widget is using an UISretch object as anchors' target.

Usually onScreenResize won't be called on mobile devices except one situation: lock the android device when game running (I was using Sony Z1) and unlock it, you will receive two on ScreenResize call which the first one report change with portrait screen size then the second one with landscape screen size.

Do you see any issues with this change?

Thanks

Jobe

It only happens on device on Android (IL2CPP).  No idea why, but like I said the null check fixed it up.

We believe is an issue inside UIAnchor.Update where mTrans is null.  Adding null checks for mTrans seems to resolve the issue.
