custom function help (jass in sc2?) +rep for answers

[GFreak45]

i made a custom function that is all custom text, and this is what i put in it:

struct AdvancedIndexing
    unit Index_Unit
endstruct
//below is the function you call to get the unit from an index
library AdvancedIndexLib
    function GetUnitIndex takes integer i returns unit
        return udg_Indexed_Unit = i.Index_Unit
    endfucntion
endlibrary
//below are the triggers saving units and refreshing them
scope
    private function Actions1 takes nothing returns nothing
        local AdvancedIndexing t = AdvancedIndexing.create
        set t.Index = EventUnit//like GetTriggerUnit
    endfunction

    private function Actions2 takes nothing returns nothing
        call Wait(60.0, c_timeReal)
        if ((UnitIsAlive(EventUnit)), ==, false)
            call UnitGetCustomValue((EventUnit()), 0).destroy//destroys this unit's instance of the struct
            call UnitSetCustomValue((EventUnit()), 0, 0.0)//sets the custom value of the unit to 0 again
        endif
    endfunction

    private function Conditions1 takes nothing returns bool//condition for checking if a unit is already saved
        if ((UnitGetCustomValue((EventUnit()), 0)), ==, 0.0)), ==, true)//custom value = 0 condition
            return true
        endif
        return false
    endfunction

    private function Conditions2 takes nothing returns bool//conditions for removing non-hero units
        if ((UnitTypeTestFlag((UnitGetType((EventUnit()))), c_unitFlagHero)), ==, false)//unit is a hero condition
            return true
        endif
        return false
    endfunction

    function OnInit takes nothing returns nothing
        local trigger t1 = CreateTrigger()
        local trigger t2 = CreateTrigger()
        call TriggerAddEventUnitRegion(t1, (RegionEntireMap()), true)//event: any unit enters playable map area
        call TriggerAddCondition(t1, Filter(function Conditions1))
        call TriggerAddAction(t1, Actions1)
        call TriggerAddEventUnitDied(t2, null)//event: any unit dies
        call TriggerAddCondition(t2, Filter(function Conditions2)
        call TriggerAddAction(t2, function Actions2)
    endfunction
endscope

first of all, would this work in jass with the proper substitutions?
second of all, will this work in sc2 to store a unit and get a integer back from the unit and visa-versa, then recycle them 60 seconds after they die if they are still dead?

PS. if you would like to use this as a resource you can use:

• Custom Script: set udg_(your variables code) = GetUnitIndex(whatever number you are using)
