Not detecting an item in inventory

12-11-2007, 09:27 PM

I'm trying to make an item that will has a chance to restore mana when a unit casts a spell. Here is the whole trigger.

JASS:

function Trig_Mana_Regain_Effect_Actions takes nothing returns nothing
    local integer random = GetRandomInt(1,100)
    local integer chance = 0
    local unit u = GetTriggerUnit()
    local real mana = GetUnitState(u, UNIT_STATE_MANA)
    local location l = GetUnitLoc(u)
    local real managain
    local integer i = 1
    loop
        exitwhen i > 6
        if GetItemTypeId(UnitItemInSlot(u,i)) == 'I017' then
            set chance = 20
            set managain = 50.00
        endif
        set i = i + 1
    endloop
    if random < chance then
        call SetUnitState(u, UNIT_STATE_MANA, (mana+managain))
        call CreateTextTagLocBJ( ("+ " + I2S(R2I(managain)) ), OffsetLocation(l, ( I2R(StringLength(("+ " + I2S(R2I(managain))))) * -9.00 ), 15.00), 0, 10, 20.00, 20.00, 100.00, 0 )
        call SetTextTagVelocityBJ( GetLastCreatedTextTag(), 80.00, 90 )
        call SetTextTagLifespanBJ( GetLastCreatedTextTag(), 1.50 )
        call SetTextTagFadepointBJ( GetLastCreatedTextTag(), 1.00 )
        call SetTextTagPermanentBJ( GetLastCreatedTextTag(), false )
        call RemoveLocation (l)
    endif
    set u = null
    set l = null
endfunction

//===========================================================================
function InitTrig_Mana_Regain_Effect takes nothing returns nothing
    set gg_trg_Mana_Regain_Effect = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_Mana_Regain_Effect, EVENT_PLAYER_UNIT_SPELL_EFFECT )
    call TriggerAddAction( gg_trg_Mana_Regain_Effect, function Trig_Mana_Regain_Effect_Actions )
endfunction

This line in particular seems to not work

JASS:

if GetItemTypeId(UnitItemInSlot(u,i)) == 'I017' then

I put a debug message in the 'if' part, but it shows that the if statement is returning false even thought the unit has the item. I'm sure I'm missing something really simple, but I can't seem to see it.

Thanks ahead of time.

weaaddar	UnitItemInSlot indexes the inventory from 0, not 1. The fix would be local integer i = 0 loop exitwhen i == 6 if GetItemTypeId(UnitItemInSlot(u,i)) == 'I017' then set chance = 20 set managain = 50.00 endif set i = i + 1 endloop
