Objects using Mob procs

Is there a way to make an object call a mob proc on usr? basically what I want to do, is make objects which are clickable which call a spell proc. But it wont let me call the proc(Gives me bad proc) because its an object, and the spell is a mob proc. Is there a way around this?

Thanks,
Alathon

                usr.castfire()
        Click()

    proc
        castfire()
            usr << "You casted FIRE!"

Still giving me a bad proc. The proc im calling is inside another file would that have anything to do with it?

Im having trouble with a list again. The way im passing spells now (or trying to..) is scribing them into a Spellbook object. But, I cant seem to call it right, or somethings wrong. Heres the scribe command which puts an object inside Spellbook, and the part where i define spellbook.

obj
Spellbook
var
newlist/Spells = list("")



Scribe(obj/O as obj in src.contents, Spellbook in src.contents)
set category = "Skills"
if(O.typea != "Scroll")
src << "Thats not even a scroll!"
if(O.Slevel > src.Level)
src << "Your too low level to even use the spell..."
else
Spellbook.Spells.Add(O)
src.contents -= O
src << "You scribe [O] into your Spell Book"

Scribe is a mob proc, and the error is:
Spells.dm:174:error:Spellbook.Spells.Add:bad var

Thanks

Im not certain about this, but when you examine the Spellbook.Spells, you are referencing something that may not exist. You created the list for Spells inside a var called newlist. I guess you can either remove this or make the call to the Spells list contained under Spellbook be more specific (I dunno the exact syntax, but maybe Spellbook/newlist/Spells whenever you want to add)
Of course, this may not be the problem at all, in which case, my bad

Actually all I need to know is how to reference to Spellbook inside usr.contents in Scribe(in here..)

Atm its Scribe(obj/O as obj in usr.contents, Spellbook in usr.contents) I know that doesnt work and I know what its saying I just dont know how to check if the user has a spellbook in that line? or do I do it later in Scribe? Im confused now :(

No. But if the proc you're calling is not in the top-level node of mob (defined directly under mob), then the compiler will stop you because usr could conceivably be any mob, and it doesn't know for a fact that usr will have this proc. You have two choices.

One: use the : operator instead of the .

Advantages: One tiny change.

Disadvantages: Unless you're absolutely, positively, 100% certain that you will never, at any point in this project, have any playable mobs that don't have that proc (is this a wizards-only thing? will warriors have this proc? if all players have it, what about GMs? can they possess NPC mobs that wouldn't have this proc?), you risk getting run-time errors... which translates into bugs.

Two: Declare a variable and do some type-checking.

cast()
if (istype(usr,/mob/player/wizard))
var/mob/player/wizard/w = usr
w.fireball()
else
usr << "Thou artn't not, er, thou not be, er... thou be'st nary... um... you're not a wizard!"

Thanks, works now :)
