[JASS] Count items of same type?

[machris13]

i was planning to make a trigger that counts an item in a units inventory only of the same type...
actually i know how but i want to ask some suggestion from you guys if there could be better from using global variables...

You can also do this:

• Actions
  • For each (Integer A) from 1 to 6, do (Actions)
    • Loop - Actions
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • (Item-type of (Item carried by (Triggering unit) in slot (Integer A))) Equal to Inferno Stone
        • Then - Actions
          • Set Count = (Load (Key many) of (Key (Triggering unit)) from Hasht)
          • Hashtable - Save (Count + 1) as (Key many) of (Key (Triggering unit)) in Hasht
        • Else - Actions
  • Game - Display to (All players) the text: (String((Load (Key many) of (Key (Triggering unit)) from Hasht)))
  • Hashtable - Clear all child hashtables of child (Key (Triggering unit)) in Hasht

Edit: Oh wait, you want it in Jass?

Easy:

function CountHeroItemsOfType takes unit whichUnit, integer itemId returns integer
    local integer index = 0
    local integer count = 0
    loop
        if (GetItemTypeId(UnitItemInSlot(whichUnit, index) == itemId) then
            set count = count + 1
        endif
 
        set index = index + 1
        exitwhen index >= 5
    endloop
 
    return count
endfunction
 
function Actions takes nothing returns nothing
    if CountHeroItemsOfType(GetTriggerUnit(),'ankh') >= 2 then
        //Actions
    endif
endfunction

@Bribe

nice dude but can you give me some explanation about the jass you gave? i really dont get the point of whichunit...that chews my brain so hardly..

function CountHeroItemsOfType takes unit triggeringUnit, integer itemRawCode returns integer // returns the number of specified items
    local integer i = 0
    local integer itemsFound = 0
    loop
        if (GetItemTypeId(UnitItemInSlot(triggeringUnit, i) == itemRawCode) then
            set itemsFound = itemsFound + 1 // Then we've found the item we're looking for; so add one to "items found"
        endif
 // stuff for the loop; nothing special:
        set i = i + 1
        exitwhen i >= 5
    endloop
 
    return itemsFound // returns the value "number of items found of rawcode 'ankh'
endfunction
 
function Actions takes nothing returns nothing
    // function CountHeroItemsOfType requires two parameters; the first one is a unit, the second is the rawcode of the item.
    if CountHeroItemsOfType(GetTriggerUnit(),'ankh') >= 2 then // Inputs GetTriggerUnit() as the parameter unit, 'ankh' as the item rawcode.
        // Actions (do your stuff here)
    endif
endfunction
