Tweening relative offset in anchor

[nkls]

Hi,
I have made a custom script that tweens the relative offset in an anchor. I want to animate widgets from the left of my screen to a relative position, say 75%. The reason why I am doing it this way, is because I want the animation to be independent of screen size.  The tween-position doesnt work if the width of the screen changes to much.

My script works fine, and everything seems to be ok. My hierarchy looks like this:

UIRoot
  - UIAnchor (this object also has a UIAnchorTween-script and a Panel script attached.)
          -Widgets
 
Is this the right way to do this? Or is there a better way?

That's perfectly fine.

I was trying to accomplish the same thing. Would you mind sharing this script? Or, is there another way to accomplish the same thing now in NGUI?

Thanks in advance.

I figured it out. I just used the default NGUI tween scripts as a reference and created a TweenOffset Script. I have included it in this post in case anyone finds it useful.

Cheers!

Hi,

the Script ist exactly what I need but I can't get it to work.

Can you help me on how do I use the script?

Greetings

Anyone else got the TweenOffset to work for UIPanel yet?
Tried this, no luck at all.
