Question on "Jittering Edges" when Moving Sprites (Anti-Aliasing Issue?)

[blitzer]

Hello everyone, I'm working on making a "looping scroll" background that scrolls and eventually loops back to the first image, which is straight forward enough. However, I'm coming across a problem where, when moving the widgets, the edges of the widgets shake/jitter a bit as they move across the screen.

I made a quick video that hopefully shows this clearly enough:

Obviously, the rotated sprite has aliasing issues, and I'm guessing that even the "aligned" sprites issue is still from aliasing? I guess I've just never noticed it happen on "aligned" textures before, just looking for someone to confirm or deny that conclusion.

Any ideas appreciated, thank you for reading.

What version of NGUI are you using? When scrolling stuff you should ensure that you're using whole integer values for positions, otherwise pixels will fall in-between of actual screen pixels, leading to undesired results. Do actual tween lerping in floats, but when setting the transform position use rounded values.

What version of NGUI are you using?
-> 3.7.4

Basically what I'm doing is calling UIScrollView.MoveRelative(my offset), so substituting a mouse drag with code. I figured that was the "safest" way of doing it since it uses methods NGUI already implemented.

My hierarchy for doing this:
Panel[UIPanel, UIScrolView]
-WrappedObjectsParent[UIWrapContent]
--Sprite1
--2
--etc.

Please update. 374 is very old. If this is the issue I'm thinking of, it was fixed many months ago.
