youkaiz	I making a spell here and i need attach an struct to caster, how do it? I ever used TimerUtils but this spells don't have timers, have something like TimerUtils to use in Units? I tryed to use HSAS but it is too hard for me , i don't know how to use it , if someone can explain how to use HSAS thanks.

PurplePoot	What do you want to attach a struct to a unit? Anyhow, H2I + StoreInteger is a quick and easy way to do it. The hashes are slightly more efficient (or so they claim), but /care. call StoreInteger(myGC,I2S(H2I(myUnit)),"My Field Name",myStruct) Then retrieve with GetStoredInteger.

Easiest way:

call SetUnitUserData(u, integer(Your_Struct))

Disadvantage, if other spell or the same spell is casted while this one is active, then it will be overwritten.

Other option is to use Table, it's totally MUI and you can attach to the same unit different struct data. The only issue is that is slow for uberfast code procedure, if this is not the case, then this can be your best bet.

Other option is PUI. I've never needed but there's people who love it.

youkaiz	But everyone say the Handle Vars(Game Cache) is bad and slow, i don't know if have something better to use. I Have PUI on my map but i don't know how to use it on struct. is something like, create an integer array and use PUI index to store struct in array?

moyack	handle Vars IS NOT EQUAL to gamecache. Use Table, which is optimized and safer than Handle Vars. And remember this: Any systems/script will be bad for you if you don't use it properly.

Alevice	moyack alternatives are pretty good. Except the first one.

Vexorian	Table works, notice: Table's main disadvantage is not speed (that's kind of irrelevant) but that units could be recycled and thus your table attach to some ghost, this is approachable with a unit group. Go UnitIndexingUtils/PUI if you are lazy - Only disadvantage is the UserData usage. No matter what you pick you'll need to be careful about leaks.

youkaiz	How i can use tables for it? set t = Table.create() set t[GetTriggerUnit()] = r Plz can make an exemple or something?

Alevice	JASS: set t = HandleTable.create() set t[GetTriggerUnit()] = myStruct

I trying here, but how recover value?
t is integer or don't need?
Whats is wrong?

JASS:

scope Revenge

private struct ReData
    real dmg
endstruct

//store damage taken
private function Damage takes nothing returns nothing
    local ReData r = t[GetTriggerUnit()]
    set r.dmg = r.dmg+GetEventDamage()
endfunction

private function IsSpell takes nothing returns boolean
    return GetSpellAbilityId() == 'A02M'
endfunction

//damage units with damage taken
private function Explode takes nothing returns nothing
    local ReData r = t[GetTriggerUnit()]
    call DamageArea(GetTriggerUnit(),r.dmg,GetUnitX(GetTriggerUnit()),GetUnitY(GetTriggerUnit()),600.,ENEMYS)
endfunction

private function Actions takes nothing returns nothing
    local trigger trig 
    local ReData r = ReData.create()
    set r.dmg = 0
    set t = HandleTable.create()
    set t[GetTriggerUnit()] = r
    
    set trig = CreateTrigger()
    call TriggerRegisterUnitEvent( t, GetTriggerUnit(), EVENT_UNIT_DAMAGED )
    call TriggerAddAction( t, function Damage )
    
    call TriggerRegisterUnitEvent( t, GetTriggerUnit(), EVENT_UNIT_SPELL_EFFECT )
    call TriggerAddCondition( t, Condition( function IsSpell ) )
    call TriggerAddAction( t, function Explodes )
    set trig = null
endfunction

private function Conditions takes nothing returns boolean
    return GetLearnedSkill() == 'A0G7' and GetUnitAbilityLevel(GetTriggerUnit(),'A0G7')<=1
endfunction

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

endscope

PurplePoot	You never defined the table variable (it should be a private global).

It finaly compile.

JASS:

cope Revenge

globals
    private HandleTable t
endglobals

    real dmg
endstruct

    local ReData r = t[GetTriggerUnit()]
    set r.dmg = r.dmg+GetEventDamage()
endfunction

private function IsSpell takes nothing returns boolean
    return GetSpellAbilityId() == 'A02M'
endfunction

//damage units with damage taken
private function Explode takes nothing returns nothing
    local ReData r = t[GetTriggerUnit()]
    call DamageArea(GetTriggerUnit(),r.dmg,GetUnitX(GetTriggerUnit()),GetUnitY(GetTriggerUnit()),600.,ENEMYS)
endfunction

private function Actions takes nothing returns nothing
    local trigger trig 
    local ReData r = ReData.create()
    set t[GetTriggerUnit()] = r
    set r.dmg = 0 
    
    set trig = CreateTrigger()
    call TriggerRegisterUnitEvent( trig, GetTriggerUnit(), EVENT_UNIT_DAMAGED )
    call TriggerAddAction(trig, function Damage )
    
    
    set trig = CreateTrigger()
    call TriggerRegisterUnitEvent( trig, GetTriggerUnit(), EVENT_UNIT_SPELL_EFFECT )
    call TriggerAddCondition( trig, Condition( function IsSpell ) )
    call TriggerAddAction( trig, function Explode )
    set trig = null
endfunction

private function Conditions takes nothing returns boolean
    return GetLearnedSkill() == 'A0G7' and GetUnitAbilityLevel(GetTriggerUnit(),'A0G7')<=1
