Scrub the previous, i had another smoke break (who'd have thought smoking was a brain enhancing pass time!), and i've for the first time (in the two years i've been trying to work it out) actually worked out how to add a firespot for weapons, and i've added a simple throw animation, so you can just add whatever weapon you like into the hasweapon = field in the fpe file.
I've just tested it with the staff and stones, and they work fine.
Just so you're aware though, third person is very rudimentary, you can fire from standing, and you can fire from walking, but it will only play the throw animation if you are standing still, it's a flaw of the system, i don't know if there's anything (short of the third person controller being redesigned) that will fix it.
So long story slightly less long, you can add a weapon to it, but you will have to get a snowball weapon from someone else as i can't make weapons.
