It's basically a box. 
 
min_x = west x location 
min_y = south y location 
max_x = east x location 
max_y = north y location 
dist = distance it will roam from where it randomly spawns 
delay = time before the NPC switches into a random direction 
 
to see an npc roam anywhere, #ai roambox when an NPC is targeted 
 
hope that helps!
