Hunting for a get_true_dir proc.

Well, a few weeks back I stumbled across a few useful proc's that I can't seem to find now that I'm actually looking.

I know it had some great features like getting a true direction (which I'd really like for my ai system)

If anyone can find this, or knows who made it, that would be great. Thanks!

This doesn't go here. I'm pretty sure Nadrew made it, though.

Thanks again; I've been battling with it for a while now, but am unsure of how to use the return values.

My attempt:

                var/direction
                var/a=advanceddirection(src,src.target)
                var/return_val=a.
                if(return_val=="Northeast")
                    direction=NORTHEAST
                else if(a=="Northwest")
                    direction=NORTHWEST
                else if(a=="Southeast")
                    direction=SOUTHEAST
                else if(a=="Southwest")
                    direction=SOUTHWEST
                else if(a=="North")
                    direction=NORTH
                else if(a=="South")
                    direction=SOUTH
                else if(a=="East")
                    direction=EAST
                else if(a=="West")
                    direction=WEST
                step(src,direction)
                world<<"stepping [a]"
            speedstop=0



My suspicion is that I'm returning a true value every time and the compiler isn't actually comparing the text, but rather just comparing that it's an empty text string or not.

Does anyone know how I can use the return values easier? The var/return_val was my attempt at finding the real return value, but obviously I have no idea what I'm doing.

Thanks!

EDIT: By the way, ignore the indentation, and yes, I know I could use a switch here. Just figured I'd point that out before anyone said anything. I just chose that to, and don't ask me why. :p

This is demonstrating some very odd behavior when I actually try to apply it as movement, rather than a text value. How would I go about this?

Make sure you know what precise value the proc returns. 
proc/advanced_direction_numeric(..args..)
   switch(advanced_direction_thing(..args..))
      if("North") return NORTH
      if("East") return EAST
      if("West") return WEST
      if( //....

Then use this custom proc that converts the returned value to numbers first, instead.

Way back, I wrote something that might be helpful to you: [link]

The get_approx_dir() function basically is like get_dir() but it will return cardinal directions when it's close enough.
