the problem is I don't know how to make the script to recognize the amount of item that player have.
first time I thought it's not big deal cos' I thought looping script can solve the problem. so I made this script
Ammo Property DraugrArrow Auto
Ammo Property PvSqSteelDraugrArrow Auto
int counter = 0 ;variable counter is undefined
EVENT OnEffectStart(Actor akTarget, Actor akCaster)
While counter <= 100
if caster.getItemCount(draugrarrow) >= 1
caster.removeItem(draugrarrow, 1, TRUE)
caster.addItem(PvSqSteelDraugrarrow, 1, FALSE)
EndIF
counter += 1 ;Shorthand for "counter = counter + 1"
EndWhile
endEVENT
and this worked very well... except the speed............... (the script changed a arrow one by one so it takes like a forever....)
so now I need solutions to make the script to recognize how many item player have(to change all items that player have at once) or to make my own scrip faster.
PLEAS HELP ME OUT!
