Multiboard Set Item Width an easy way to do progress bars?

I'm a lazy bastard. I'm trying to use the multiboard-set item width action to create a progress bar.

What i've done is made a multiboard cell that has just a LOONG chunk of ||||||||||||||||||||||||||||||||||s as text. I'm trying to reduce the width of that column to truncate off the extra |s.

Unfortunately I'm not having much luck. Could anyone explain how the Set Item Width action really works and perhaps explain if this method is even possible?

I don't know much about your problem, but I think it would be easier if you just use ||||||||||||| characters with different colors

Eh? Hmmm that's a good idea. Thanks Vex.

yes use them as different colours, and put a set amount relative to a percantage

ie. 10 "||||||||||" and have it that every 10% of hp taken off changes the color of one bar.
