Big problems i can't understand

[Roku]

Hey, well im trying to make this triggered spell, which works like this: the unit places down the healing stream totem (ward), and then units withing 600 range of the totem get healed every 2 sec, based of the heroes int. Here's my trigger:

scope LHT

globals
//**************************************************************************************************    
    private constant integer SumUnit = 'o001' // Ward Rawcode
    private constant real HealBase = 100 // Totem Base-Heal
    private constant real TotemRadius = 600 // The AoE affected by the totem
    private constant real Interval = 2 // Healing Interval
    private constant real LifeSpawn = 60 // The totem's duration
//**************************************************************************************************
    
    private location array Totloc
    private integer pt
    private unit array caster
    private integer pc
    private unit array affected
    private integer pa
endglobals

struct LHT
    unit caster
    real heal
    real dur = 0
    location tl
endstruct

private function Cond takes nothing returns boolean
    return GetUnitTypeId(GetSummonedUnit()) == SumUnit
endfunction

private function Unit_Filter takes nothing returns boolean
    if IsUnitEnemy(GetFilterUnit(),GetOwningPlayer(caster[pc])) then
		return false
	endif
    if(IsUnitType(GetFilterUnit(),UNIT_TYPE_MAGIC_IMMUNE)) then
       return false
    endif
	if(IsUnitType(GetFilterUnit(),UNIT_TYPE_STRUCTURE))then
		return false
	endif
	if GetUnitTypeId(GetFilterUnit()) == SumUnit then
		return false
	endif
    return true
endfunction

private function setaffected takes nothing returns nothing
    local unit a = GetEnumUnit()
    //call PingMinimapLocForForce(bj_FORCE_ALL_PLAYERS, GetUnitLoc(a), 2)
    //set affected[pa] = null
    set pa = GetUnitIndex(a)
    set affected[pa] = a
    set a = null
endfunction

private function Heal takes nothing returns boolean
    local LHT data = ABCT_GetData()
    local real h = data.heal
    local unit a
    local group af    
    local location sp = data.tl
    local location p
    local unit u
    
    call BJDebugMsg("Healing...")
    //set affected[pa] = null
    call BJDebugMsg("Healing2...")
    call PingMinimapLocForForce(bj_FORCE_ALL_PLAYERS, Totloc[pt], 2)
    set af = GetUnitsInRangeOfLocMatching(TotemRadius, Totloc[pt], Condition(function Unit_Filter))
    call ForGroup(af, function setaffected)
    set a = affected[pa]
    set p = GetUnitLoc(a)
    call CreateNUnitsAtLoc( 1, 'h005', GetOwningPlayer(a), p, bj_UNIT_FACING ) // Adding a dummy buff to the affected units
    set u = bj_lastCreatedUnit
    call UnitAddAbility(u, 'A022')
    call IssueTargetOrder( u, "bloodlust", a )
    call UnitApplyTimedLife(u, 'BTLF', 2.00)
    if data.dur == LifeSpawn then
    call data.destroy()
    set data.dur = 0
    return true
    else
        set data.dur = data.dur + Interval
        //call PingMinimapLocForForce(bj_FORCE_ALL_PLAYERS, GetUnitLoc(a), 2)
        call BJDebugMsg("Healing...")
        call SetUnitState(a, UNIT_STATE_LIFE, GetUnitState(a, UNIT_STATE_LIFE) - (h/50 + HealBase))
    endif
        
    call DestroyGroup(af)
    //call RemoveLocation(sp)
    call RemoveLocation(p)
    set af = null
    set a = null
    set u = null
    //set sp = null
    set p = null
    
    return false
endfunction

private function action takes nothing returns nothing
    local LHT data = LHT.create()
    local unit c = GetSummoningUnit()
    local unit s = GetSummonedUnit()
    local location sp = GetUnitLoc(s)
    local integer i = GetHeroInt(c,true)
    local real cr = I2R(i)
    local group af 
    set pt = GetUnitIndex(s)
    set Totloc[pt] = GetUnitLoc(s)
    set pc = GetUnitIndex(c)
    set caster[pc] = c
    //set af = GetUnitsInRangeOfLocMatching(TotemRadius, sp, Condition(function Unit_Filter))
    //call ForGroup(af, function setaffected)
    set data.tl = sp
    set data.heal = cr
    call PingMinimapLocForForce(bj_FORCE_ALL_PLAYERS, data.tl, 2)
    call ABCT_Start(function Heal, data, Interval)
    
    call RemoveLocation(sp)
    call DestroyGroup(af)
    set af = null
    set c = null
    set s = null
    set sp = null
endfunction

    //===========================================================================
function InitTrig_Totem takes nothing returns nothing
    local trigger t = CreateTrigger()
    call TriggerRegisterAnyUnitEventBJ( t, EVENT_PLAYER_UNIT_SUMMON )
    call TriggerAddCondition( t, Condition( function Cond) )
    call TriggerAddAction( t, function action )
endfunction

endscope

Basically the thing i dont understand is that whenever i use the function "set affected[pa] = null" all the remaining actions of the trigger get skipped. Doesnt matter where i insert it, all the other things after it get ignored. I would need this, so if a unit leaves the 600 range of the totem, it doesnt get healed anymore. Any help appreciated!

pa is uninitialized.

You should use war3err.

 

[Roku]

Could you tell me more about war3err and how to use it? Never heard of it. And what do you mean by uninitialized?

 

[Uberplayer]

Enable it from the NewGen's Grimoire menu. I guess it's the one that shows you these ingame:

Op Limit - Execute 300,000 bytecode operations
Divide by zero - Divide by integer or real 0
Var use - Attempt to get the value of an uninitialized var
ExecuteFunc("func") - If func does not exist or func has arguments, this stops a crash.
Player(x) - If x > 15 or x < 0

In your case, it would be this:
Var use - Attempt to get the value of an uninitialized var

Yes, i have and had that box checked ("enable war3err"), my spell still doesnt work.

EDIT: Ehm, i finally got your point, and gave pa the initial value of 1 at the start of the trigger (declaration of globals). It works now. +rep
