I'm having trouble with my attack. it goes:
obj
    var
        mob/owner
obj
    sword
        icon = 'spells.dmi'
        icon_state = "gemsword"
        New()
            for(var/mob/M in src.loc)
                var/damage = src.owner.damage
                M.HP -= damage
                world<<src.owner
                deathcheck(M,src.owner)
                flick("attack",src.owner)
                flick("hit",M)
                M << "[src.owner] attacks you for [damage] damage"
                src << "You do [damage] damage to [M]"
                spawn(5)
                del(src)
            spawn(4)
            del(src)
mob/verb/sword()
    var/obj/sword/S = new/obj/sword(get_step(usr,usr.dir))
    S.owner = usr
    S.dir = usr.dir

The runtime error I get only happens when I attack another mob, when I just attack at nothing, it works. The runtime is:
runtime error: Cannot read null.damage
proc name: New (/obj/sword/New)
  source file: fight.dm,10
  usr: Aleis (/mob)
  src: the sword (/obj/sword)
  call stack:
the sword (/obj/sword): New(the path (22,20,1) (/turf/floor/path))
Aleis (/mob): sword()
Aleis (/client): Northeast()

Your problem is that you never set the obj's owner variable. Therefore, src.owner is null.
