        name = "fire"
        screen_loc = "4,2"
        Click()
            if(usr.mp >= 5)
                var/mob/M = locate(/mob) in get_step(src,src.dir)
                if(M != null)
                    var/obj/O = new/obj/fire(M.loc)
                    usr.mp = usr.mp - 0
                    var/damage = (rand(1,7 + round(usr.level / 3,1))) - M.def
                    if(damage <= 0)
                        damage = 1
                    M.hp = M.hp - damage
                    s_damage(M, damage, "#FF0000")
                    usr << sound("sfx/Fire.wav",0)

In response to Madpeter (#1)
have you defined mp as a mob variable?

mob
var
mp

(No copy and paste cause of spaces)also put ur other major stats there like hp

How much of this gets executed, like does the fire object appear, does the s_damage appear of the mob, and does the sound play. Are there any run-time errors when executing this? Please provide any information on these points.

there is no effects and no runtime errors.

[edit]
fixed it
var/mob/M = locate(/mob/) in get_step(usr,usr.dir)

forgot to add the last / after the locate mob bit :)

src is the object, and it doesnt have mp, usr does. Otherwise I dont understand where that problem is because src.mp is not in the code above.
