Timer Help

1st time trying to use a timer for an ability..

JASS:

function Trig_Blood_Transfer_Conditions takes nothing returns boolean
    return GetSpellAbilityId() == 'A04D'
endfunction

function BloodTransfer takes timer t returns nothing
    local unit a = GetSpellAbilityUnit()
    local unit c = GetSpellTargetUnit()
    local integer i = GetUnitAbilityLevel(a, 'A04D')
    local real g = GetUnitState(a, UNIT_STATE_LIFE)
    local integer b

        if g <= 1500 then
            set b = 0
            call UnitRemoveAbility( c, 'B012' )
        elseif g > 1500 then
            set b = 1
        endif

    if b == 1 then
        call BJDebugMsg("3")
        call DestroyEffect( AddSpecialEffect( "Objects\\Spawnmodels\\Demon\\DemonBlood\\DemonBloodPitlord.mdl", GetUnitX(a), GetUnitY(a) ) )
        call DestroyEffect( AddSpecialEffect( "Objects\\Spawnmodels\\Demon\\DemonBlood\\DemonBloodPitlord.mdl", GetUnitX(c), GetUnitY(c) ) )
        call UnitDamageTarget( a, c, 1, false, true, ATTACK_TYPE_CHAOS, DAMAGE_TYPE_UNIVERSAL, WEAPON_TYPE_WHOKNOWS )
        call SetUnitState( a, UNIT_STATE_LIFE, g - 1 )
    elseif b == 0 then
        call PauseTimer(t)
        call DestroyTimer(t)
    endif

    set a = null
    set c = null
    call BJDebugMsg("4")
endfunction

function BloodTransfer_Effect takes nothing returns nothing
    call BloodTransfer(GetExpiredTimer())
endfunction

function Trig_Blood_Transfer_Actions_Core takes timer t returns nothing
    local unit a = GetSpellAbilityUnit()
    local real r = I2R(GetUnitAbilityLevel(a, 'A04D'))
    
    call SetUnitState( a, UNIT_STATE_LIFE, GetUnitState(a, UNIT_STATE_LIFE) - (100 * r) )
    call TimerStart( t, 0.60 - (r * 0.15), true, function BloodTransfer_Effect )
    
    set a = null
            call BJDebugMsg("2")
endfunction

function Trig_Blood_Transfer_Actions takes nothing returns nothing
    if GetUnitState(GetSpellAbilityUnit(), UNIT_STATE_LIFE) > 100 * GetUnitAbilityLevel(GetSpellAbilityUnit(), 'A04D') then
        call BJDebugMsg("1")
        call Trig_Blood_Transfer_Actions_Core(CreateTimer())
    endif
endfunction

//===========================================================================
function InitTrig_Blood_Transfer takes nothing returns nothing
    set gg_trg_Blood_Transfer = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_Blood_Transfer, EVENT_PLAYER_UNIT_SPELL_EFFECT )
    call TriggerAddCondition( gg_trg_Blood_Transfer, Condition( function Trig_Blood_Transfer_Conditions ) )
    call TriggerAddAction( gg_trg_Blood_Transfer, function Trig_Blood_Transfer_Actions )
endfunction

When i test this, it shows 1,2,4 once
2 things are wrong here.

1, the timer should keeping going, so wouldnt the 3 and the 4 show until the timer stops?

2, The 3 does not show...why?

rain9441	GetSpellAbilityUnit and GetSpellTargetUnit will never return a valid unit inside a timer function. You're going to have to store both of those units in some fashion that your timer function can access them. It can be smart timers, gamecache, global variables, or anything else your clever mind can think up. Run through the code again but picture the local variables a and c as null.

Joker	What are smart timers? Edit: Ok i found out what SmartTimer is

Vexorian	Nah, he means that you have to attach information to the timer (which is a horrible approach although it works) You may start with something easy like "handle vars" JASS: //After creating the timer, before starting it cal SetHandleHandle(t, "target", GetSpellTargetUnit()) //When the timer expires: call KillUnit(GetHandleUnit(t,"target"))
