permanent summons, but limit at a time

I actually created a spell based on Dark Portal which allows me to spawn permanent summons. and i wanted to limit the total amount of spawns at a time.Thus, I create this following triggers, (ideas gotten from somebody else).


function Trig_Herd_Leaders_Level_1_Copy_Conditions takes nothing returns boolean
if ( not ( GetUnitTypeId(GetSummonedUnit()) == 'n00S' ) ) then
return false
endif
return true
endfunction

function Trig_Herd_Leaders_Level_1_Copy_Func001001 takes nothing returns boolean
return ( udg_HerdCurrentSpawn[1] == null )
endfunction

function Trig_Herd_Leaders_Level_1_Copy_Actions takes nothing returns nothing
if ( Trig_Herd_Leaders_Level_1_Copy_Func001001() ) then
set udg_HerdCurrentSpawn[1] = GetSummonedUnit()
else
call RemoveUnit( udg_HerdCurrentSpawn[1] )
endif
set udg_HerdCurrentSpawn[1] = GetSummonedUnit()
endfunction

//===========================================================================
function InitTrig_Herd_Leaders_Level_1_Copy takes nothing returns nothing
set gg_trg_Herd_Leaders_Level_1_Copy = CreateTrigger( )
call TriggerRegisterAnyUnitEventBJ( gg_trg_Herd_Leaders_Level_1_Copy, EVENT_PLAYER_UNIT_SUMMON )
call TriggerAddCondition( gg_trg_Herd_Leaders_Level_1_Copy, Condition( function Trig_Herd_Leaders_Level_1_Copy_Conditions ) )
call TriggerAddAction( gg_trg_Herd_Leaders_Level_1_Copy, function Trig_Herd_Leaders_Level_1_Copy_Actions )
endfunction


Now the question is, what if i wanted to limit a group of units that consist only two kinds of units, and the number of units in that group have a limit between 2-4(number differs each time the spell are casted)

Can somebody tell me how to create trigger(s) for this?
spell number(dark portal)

Anyone? =( pls help me

Bump

why is it all in custom-text ?
and from this "text", migh i sugest renaming the triggers to their "proper" names ?
and if everything fails, upload the map and let someone fix it...

as for your problem, i think i know whats bothering you...when u cast your dark portal, it creates 1 to n unit1 or unit2. i guess you want to limit the number of unit1 to x and/or unit2 to y.

so, try something like this, make 2 variables "Unit1Count" and unit2count which will be integer variables...

now the trigger:
E:unit is summoned
C:summoned unit-type equal to unit1-type
A:set unit1count to (unit1count + 1)
this one will increase for every unit1 summoned, so u need a trigger that will deplete it when the unit is killed (since it can't unsummon itself out by running out of time), also do it for unit 2
E:unit is killed
C:none
A:if (unit type of (dying unit) equals to (unit1-type) then do (set unit1counter = (unit1counter - 1))) <- something like this...also do it for unit2
this trigger will reduce the integer counting the summoned units, and now the part u need...
E:unit is summoned
C:none or summoning unit equal to (your hero having that skill)
C:summoned unit-type is unit1-type
A: if Unit1Count equal to 4, then remove summoned unit from game, else do nothing

u might want to consider trying these triggers since u don't have any solution...hope it helps :)

yah, i think this may be the best alternative. Thanks alot for your help, I paste the trigger in custom text as I have no idea of how to paste the GUI version to the board. I'll make sure to rename those text to their 'proper' names next time i encounter any problems. Thanks again.
