Check whether unit has an item

leric	What are the correct parameters to pass into this function for item? JASS: native UnitHasItem takes unit whichUnit, item whichItem returns boolean Cannot just pass name(string), or item id(integer) or is there a way to convert them to an item?

Naakaloh	The item argument for the UnitHasItem function refers to an item object not an ID. If I remember correctly, you need to perform a comparison of the itemTypeID for each of the items carried by the unit. Try using: JASS: native GetItemTypeId takes item i returns integer

Anitarf	You are probably looking for UnitHasItemOfTypeBJ.

JASS:

function UnitHasItemType takes unit u, integer id returns integer
    local integer i=0
    local integer m=UnitInventorySize(u)
    loop
        exitwhen(i==m)
        if (GetItemTypeId(UnitItemInSlot(u, i))==id) then
            return i
        endif
        set i=i+1
    endloop
    return -1
endfunction

Here, rather than using a function that calls another function, just use this function. It returns -1 if the unit does not have the item, and if the unit does have the item then it will return the slot index of the first "appearance" of the item-type in a unit's inventory.
