mob/verb
    Fire()
        var/vch=0
        for(var/x,x<=5,x++)
            for(var/mob/M in ohearers(x,src))
                if(M)
                    vch++
                    break
            if(vch) break
        if(vch)
            world<<"Mob found"
        else
            world<<"No mobs found"
        src<<"End Check"

Is there a more efficient way of finding the closest (visible) mob ^-- like that, only without looping through each ohearers?

Garthor	view() and related procs are already sorted by distance.

When around a large group of mob's it always want's to fire to the bottom-left most mob.
using:

mob/verb
    Fire()
        for(var/mob/M in ohearers(5,src))//won't fire through opaque walls
            if(M)
                missile(/obj/bullet, src, M)
                break

Garthor	Whoops, guess viewers() and hearers() sort by x-y-z, rather than distance to center. Changing it to oview() or somesuch will work.

Leur	I've used ohearers, still uses as you say x-y-z sorting. Would be nice to get an option of sorting by distance without looping the code. Think I should suggest it or stick with the loops? For anyone who wants it: Demo (Hope I made it clear enough to follow with the comments.) : http://www.byond.com/developer/Leur/ClosestMob Pretty simple to most people but shrugs.

Garthor	Again, ohearers does not sort by distance. If you want to sort by distance without having to do it yourself, use oview(), view(), orange(), or range().

Leur	oview / orange doesn't filter out the "not visible" like ohearers though. http://www.byond.com/members/Leur/files/Env_src.zip <- highlighted area is what I mean it still fires through opaque atoms.
