[Jass]Pro Creep respawn

[M_Vegeta]

im making a project, and i want to use most efficient code i can to make my map good as other do!!!

Map size 256 x 256
Over 400-500 mobs
Problem : imagin 10 player that gather over 50 mobs and kill them over time(5min exemple) huge lag happened with most gui system i tryed

System required :
Can use Jnpg editor aka newjassGen
Work on Specific region named as : CreepPoint1,CreepPoint2,CreepPoint3,CreepPoint4,
map contain over 400 mobs as Neutral hostile
Hope its could use X & Y value for location since they dont lag!!

since this forum love jass, i hope some1 will able to help me , im starting to learn jass but..... i kind of bad....

there is the code i have now, i would like it to use region in condition and unit x & Y as position

function Trig_Respawn01_Conditions takes nothing returns boolean
    if ( not ( GetOwningPlayer(GetDyingUnit()) == Player(PLAYER_NEUTRAL_AGGRESSIVE) ) ) then
        return false
    endif
    return true
endfunction

function Trig_Respawn01_Actions takes nothing returns nothing
    local unit u = GetDyingUnit()
    local location l = GetUnitLoc(u)
    local real facing = GetUnitFacing(u)
    call TriggerSleepAction( 10.00 ) //This is the wait time.
    call CreateNUnitsAtLoc( 1, GetUnitTypeId(u), Player(PLAYER_NEUTRAL_AGGRESSIVE), l, facing )
    call RemoveLocation(l)
endfunction

//===========================================================================
function InitTrig_Respawn01 takes nothing returns nothing
    set gg_trg_Respawn01 = CreateTrigger( )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_Respawn01, EVENT_PLAYER_UNIT_DEATH )
    call TriggerAddCondition( gg_trg_Respawn01, Condition( function Trig_Respawn01_Conditions ) )
    call TriggerAddAction( gg_trg_Respawn01, function Trig_Respawn01_Actions )
endfunction
