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?

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

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

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:

Pretty simple to most people but *shrugs*.

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().

oview / orange doesn't filter out the "not visible" like ohearers though.
