wats the var of the direction a mob is facing? i tried using dir but tht just affects the direction in which the client looks at the map, any help?

The last time I checked, a mob's var refers to the direction in which it is facing. Perhaps you were looking at the client's dir instead?

From the DM Reference (which you should have checked before posting!):

under client/var,
This defines the relationship between the world's coordinate system and the player's screen.

under atom/var,
This is the direction that the object is facing.

Next time, hit F1 first :-)

how can i code it in, ill give u an example of wat im doing

client/East(atom/A)
   if(A.dir == NORTH)
      A.turn(NORTH, 90)

but it now says that the dir var = null as a rintime error, any tips?

Yeah, your use of atom/a int he arguments is probably faulty. I don't think that that argument actually exists - and besides, you have the client/mob variable to use, assuming you're wanting to turn the mob. You could easily do

client/East()
  if(mob.dir == NORTH) mob.dir = WEST


turn(NORTH,90) will always return WEST, by the way. :-) According to the reference, anyway. I thought it turned clockwise, but what do I know?

If you just want the arrows to turn your mob, you could do

client/Move(loc,dir)
  if(loc) ..()
  else switch(dir)
    if(NORTH) . = step(mob,mob.dir)
    if(SOUTH) . = step(mob,turn(mob.dir,180))
    if(EAST)
      mob.dir = turn(mob.dir,270)
      . = 1
    if(WEST)
      mob.dir = turn(mob.dir,90)
      . = 1
    else . = 0


Hope that helps a little.

Look up turn(), by the way. It dosn't turn an atom, but rather returns a new direction based on the given dir and the degrees.

i know tht bit bout turn lol, the rest of the code is like EAST, 90 or WEST -90 (i accounted for degree change) but tht other bit is wat i needed, thx ^^

dang! tht bit of code u sent still makes my guy move normally, ill tell ya wat i tried to do ^^, i want to make it so left and right arrows turn the mob round and up arrow sends u in that direction

Yup. I tested and de-glitched it -- and I learned more about how client.Move() works, evidently. This works for me:

client/Move(loc)
    var/dir = get_dir(mob,loc)
    switch(dir)
        if(NORTH) . = step(mob,mob.dir)
        if(SOUTH)
            . = step(mob,turn(mob.dir,180))
            mob.dir = turn(mob.dir,180)
        if(EAST)
            mob.dir = turn(mob.dir,270)
            . = 1
        if(WEST)
            mob.dir = turn(mob.dir,90)
            . = 1
        else . = 0


Tell me if it works for you.

YAY, only one thing left now, how do i stop the output to the usr? everytime it turns i get 4 4 4 8 8 1 1 1 8 8 ...etc.
^^ thx

You sargathed it before I could remove the "world << dir" line that I put in there when I was trying to figure out why it was working wierd. Just remove that line. :-)

plus, i just improved it a little more, so it includes 8 directions without muffing up :)

client/Move(loc)
    var/dir = get_dir(mob,loc)
    switch(dir)
        if(NORTH)
            if(mob.in_car == 1)
                . = step(mob,mob.dir)
            else
                ..()
        if(SOUTH)
            if(mob.in_car == 1)
                . = step(mob,turn(mob.dir,180))
                mob.dir = turn(mob.dir,180)
            else
                ..()
        if(EAST)
            if(mob.in_car == 1)
                if(mob.dir == SOUTHEAST)
                    mob.dir = SOUTH

I thought this was strange at first also, but once I learned circle trig it made more sense. Positive angles moved the terminal side counter-clockwise while negative angles moved it clockwise.

If he wanted to simplify things quite a bit, he could always do: 
if(EAST) mob.dir = turn(mob.dir,-45)
if(WEST) mob.dir = turn(mob.dir,45)


You can use negatives ;)

Yeah, it does make sense geometrically. It's just my fault that I generally think of things in a clockwise fashion; it's easy enough to settle into the counter-clockwise geometry, especially when a proc works the opposite of what you thought it would.
