FOSS gamedev and creative worlds

I'm using a mod: mobs_npc. It gives you the option for them to be "still", or "follow" when you right click them. But I'd like an option for them to also roam around. To give a town a feeling of life. I've managed to add in several skins I created, but can't figure the roaming out. Can anyone out there help with this? I'm not sure how to paste the npc text properly here... but here is what it is:

add another option for self.order = "" on register, then it'll just walk around :)

TenPlus1, Do I put anything in the quotes ""

I've tried making a new command for them to wonder around... it's not working for me.

Try something like this:
