        Bump(mob/M)
            if(istype(M))
                var/obj/Fireball/S = new(loc + (M.x + 1))
                S.icon = 'fireball_hit.dmi'
                usr << "Hit"

mob

Problem description:

I get this error:

runtime error: Cannot execute null.Enter().
proc name: Fireballskill (/mob/verb/Fireballskill)
source file: Mainz.dm,118
usr: Darkjohn66 (/mob)
src: Darkjohn66 (/mob)
call stack:
Darkjohn66 (/mob): Fireballskill()

My fireball appears in the downward position over my mob and then deletes, it never moves or animates. I'm not sure what I am doing wrong. Please help and thank you!

Ulterior Motives	mob verb Fireballskill() var/obj/Fireball/S=new(src.loc) walk(S,src.dir) spawn(50) del S I probably can't help with your error. Though my guess is it's from calling Move() without doing S.Move(). But I did shorten your fireballskill().
