This is the code I have for my attacking, What I was wondering was how could I make it after it flicks the jacklefta icon state if it detects someone 1 space to the left of the usr it will attack him but if it doesn't it wont do anything.

mob
    battle
        verb
            Attack()
                set hidden=1
                if (usr.jack==1)
                    if (usr.icon_state=="jackleft")
                        if (usr.attacking==0)
                            usr.attacking=1
                            flick("jacklefta",usr)
                            sleep(attackdelay)
                            usr.attacking=0
                        else
                            ..()

Well, first we have to remember that BYOND doesn't think in terms of left and right, it uses east and west. Unfortunately for you, I don't think in terms of either. I'm going to take a stab and say that left is west. So, what we want to do is find the turf to the east of us.

var/turf/t = get_step(usr,WEST)

Then, we want to see if there's a mob in that square.

for (var/mob/m in t)
do stuff here
break

If you want it to keep checking to see if there's more than one mob, you leave out the break.

That's good, except that it doesn't specifically check a direction.

I just noticed that after re-reading what he wanted. Oops. Edited my suggestion to provide an alternate for what he wanted (which will work for all directions, I might add).
