Is it possible to not let NPC's move diagonally? I know you can do it for clients, but I dont know about NPC's.

Yeah sorry for all the questions lately, I'll try to make this the last for some time.

It is, although you can't use some of the pathfinding step algorithms like step_to() with that.

The main thing is to modify Move():
mob/Move(atom/newloc, newdir=0)
  if(newdir & newdir-1)   // diagonal
    newdir &= pick(3,12)
    newloc = get_step(src, newdir)
    return ..(newloc, newdir)
  return ..()

Alright that's fine since I'm only using walk_towards in my game.

Thanks a lot.

But one more thing, when using walk_towards(), is there a demo out there demonstrating how to get mobs the find there way around things like walls to get to the desired location? Like his

xxxxxxxxxxx
xxxxxMxxxxx
xxxOOOOOx
xxxxxPxxxxx

With M being the mob walking towards P and O being the wall blocking M's path, is there a demo out there showing how to get M around a wall like that and in similar situations?

Deadron has a pathfinding library which can have artificial intelligence by stepping to an item. Just search his hub entries.
