Check Item Slot

st33m	This is a short question, but is there a way to check what slot an item is in?

oddly there isn't a built in function for it, but you can use my getitemslot function

JASS:

function GetItemSlot unit hero,item it returns integer
local integer i=0
loop
   exitwhen i==6
       if(UnitItemInSlot(hero,i)==it)then
               return i
       endif
   set i=i+1
endloop
return -1
endfunction

let say you have three variables, Item it, Unit Hero, and Integer slot then you'd go
Set Hero=The Triggering Unit
Set it=The manipulated item
custom script: set udg_slot=GetItemSlot(udg_Hero,udg_it)
if the number you get back is -1 then the unit doesn't have the item.

Okay, I'm not good at JASS. How does this run? And also this checks for a specific item? So I would changew it to the item (for example ratf) and then it would check if it has it in any slot? I dont quite understand this, as it is beyond my limited scope of JASS knowledge (which I am working on, and should speed up now that school is out).

EDIT: Let me ask a real question.

How would I make something that checks what slot an item is in when a unit manipulates one and then puts that item in a variable for that hero. What I'm atempting to do is make Set Items (Have 1 item: no extra effect Have 2 items: +3 whatever Have 3 items: +7 something Have all 4: +9 blabla). What my idea was I would check all the slots when a hero gets an item and check if the hero has all the items.

Looking back, this doesnt make much sense. Is there a better way to do that?

BertTheJasser	Yes there actually is: Whenever the hero/unit picks up an item check if it is one of your defined ones, store the number (how many items of that) somewhere and update depending on that number which/how many boni the hero gets. The same when dropped.

It appears that you are actually looking for item types, not specific instances of an item.

JASS:

function UnitHasItemType unit hero, integer id returns boolean
local integer i = 0
local boolean b = false

loop
   exitwhen i == 6 or b
   set b = GetUnitTypeId(UnitItemInSlot(hero,i)) == id
   set i = i + 1
endloop

return b
endfunction
