NGUI Hud Text UI Follow Script problem

[rbattagline]

I have a health bar and an energy bar following a character, but the health bar is not perfectly following the character.  It will shift by a pixel or two.  The Energy bar doesn't have that problem, but from what I can tell I'm doing the exact same thing for the two bars.

Here's a link to a youtube video of the problem:

Any idea what the problem is?

Thanks,

Why not have only one UIFollowTarget script, with both health bars being children underneath?

That seems to have fixed the issue.

Thanks
