Code:

mob
    verb
        FireBlast()
            if (usr.MP <5)
                usr << "You don't have enough MP to use this spell!"
            else
                var/obj/fireball/F = new(usr.loc)
                walk(F,usr.dir,2)
                usr.MP -= (5)

obj
    fireball
        density = 1
        Bump(mob/M)
            if(istype(M,/mob))
                var/damage = (10)
                M.HP -= damage
                M.Death()
                del(src)
            else
                del(src)
                ..()
    verb
        Reflect()
            set src in oview(1)
            loc = usr
            walk(usr.dir,2)


Problem description:

I'm a beginner, sort of messing around making a game, and I wanted to be able to reflect a fireball. I thought I could simply make it it go in the Reflector's direction, but it only moves about one space and then continues forward. What could I do to change this so that it goes the other way (that the mob reflecting it is facing)? I was thinking of simply deleting the old one and making a new fireball, but I'd rather that it stays the same object.

And also, is there a way to cause the fireball to speed up after each reflection?

    verb
        Reflect()
            set src in oview(1)
            loc = usr
            walk(src, turn(dir,180), 2)


As for your second question, think about what you're trying to do - you're trying to keep track of the number of times the fireball has been reflected, and set the walking delay to a different number for each time.

So basically, you need a formula for turning 'number of times reflected' into a reasonable walking delay, and a count of 'number of times reflected' that goes up every time the fireball bounces off of something.

Keep in mind that you can't use delays less then 0 for walk.

Why are you moving the fireball inside the player['s inventory] first, though? ;O
(src.loc = usr)
