Question regarding NPC movement

[T_Silverwolf]

So this is going to sound like a strange question, but I was wondering if there are any scripts or drop in DECORATE/ZScript libraries out there that allow for smoother movement of characters using thing_setgoal and interpolation points. What I want to do is develop a map where the player can guide NPC marines through a given complex from the command center. But every time I've tried to use the tools I know about (pretty much just setgoal, really) the AI is really jerky and kind of lame looking.

I'm not really a coder, I don't know much about decorate or anything like that so I'm kind of wondering is there an easy or human readable solution to this, or should I just work on some other project?
