Catching when a Unit uses an Item

03-11-2009, 10:54 PM

Ok, this is really strange. I am having trouble detecting a unit using an Artifact. Actively Used is set to true, and this is the code

JASS:

scope ItemTrigger

private function Actions takes nothing returns nothing
    call BJDebugMsg("lawl")
    if GetItemType(GetManipulatedItem()) == ITEM_TYPE_ARTIFACT then
        call EquipItem(GetManipulatedItem(), GetManipulatingUnit())
    endif
endfunction

private function InitTrig takes nothing returns nothing
    local trigger t = CreateTrigger()
    call TriggerRegisterAnyUnitEventBJ(t, EVENT_PLAYER_UNIT_USE_ITEM)
    call TriggerAddAction(t, function Actions)
    set t = null
endfunction

endscope

Why is this not catching the item being used? The item has the "manual of hp" ability that adds 0 hp and plays no graphic.

moyack	Why not detect the item ability?

Already tried, does nothing as well.

JASS:

scope Test

private function Conditions takes nothing returns boolean
    return GetSpellAbilityId() == 'A02N'
endfunction
private function Actions takes nothing returns nothing
    call BJDebugMsg("lawl")
endfunction

//===========================================================================
function InitTrig takes nothing returns nothing
    local trigger t = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( t, EVENT_PLAYER_UNIT_SPELL_EFFECT )
    call TriggerAddCondition( t, Condition( function Conditions ) )
    call TriggerAddAction( t, function Actions )
    set t = null
endfunction

endscope

Edit: Forgot to type JASS at the end of Hidden. Damn ninjas.

xombie	So this function does not display "lawl"?

try this snippet and tell us what it displays when you use the item...

JASS:

scope Debug initializer Init
    // *Show Order Id
    private function showorderid takes nothing returns nothing
        local integer id=GetIssuedOrderId()
        local unit u=GetOrderedUnit()
        if(StringLength(OrderId2String(id))>1)then 
            call BJDebugMsg(GetUnitName(u)+" "+OrderId2String(id))
        else
            call BJDebugMsg(GetUnitName(u)+" "+I2S(id))    
        endif
        set u=null
    endfunction

    //INITIALIZER //=========================================
    private function Init takes nothing returns nothing
        local trigger t=CreateTrigger(  )
        call TriggerRegisterAnyUnitEventBJ(t, EVENT_PLAYER_UNIT_ISSUED_ORDER )
        call TriggerRegisterAnyUnitEventBJ(t, EVENT_PLAYER_UNIT_ISSUED_POINT_ORDER )
        call TriggerRegisterAnyUnitEventBJ(t, EVENT_PLAYER_UNIT_ISSUED_TARGET_ORDER )
        call TriggerAddAction(t, function showorderid )
        set t=null
    endfunction
endscope

Blacktastic	That isn't going to change a single thing... Edit: i have something almost identical to that in my map actually. It returns 852008

xombie	Hmmm... try changing the InitTrig to a private function and then add an initializer InitTrig at the top of the scope.

Blacktastic	That works, but I have plenty of other triggers with the function InitTrig that are all private and work just fine without initializer. Strange.

xombie	I'm not sure how well public function InitTrig works anymore, but that used to be the vJass syntax for initializers in scopes. Also, having the default function InitTrig_TriggerName might work as well.
