# Units in Group (Spell Problem)

#### Squll2

##### je'ne sais pas
Hey guys, noobey sqully here.

Anyway, what this spell is meant to do is debuff or "dot" an enemy (damaging him over time) and if he dies with it still on him, it recasts it on all the enemies around him. Howeverrrr for some reason it is no doing this and I am clueless to as why, When I added the DisplayText trigger it doesnt even come up with anything meaning the problem must be before or at the adding the units to the group part..

Edit: I added waits to see if that would help.. but it didnt

JASS:
``````function Trig_Infected_Javelin_Conditions takes nothing returns boolean
if ( not ( UnitHasBuffBJ(GetDyingUnit(), 'BNab') == true ) ) then
return false
endif
return true
endfunction

function Trig_Infected_Javelin_Actions takes nothing returns nothing

local unit u        = GetDyingUnit()
local player p      = GetOwningPlayer(c)
local real x        = GetUnitX(u)
local real y        = GetUnitY(u)
local group g       = CreateGroup()
local group g2      = CreateGroup()
local integer i     = 0
local integer level = GetUnitAbilityLevel(c, 'A008')
local integer a     = 0
local unit d
local unit e
local effect sfx

set sfx = AddSpecialEffect( &quot;Abilities\\Spells\\Other\\Drain\\DrainCaster.mdl&quot;, x, y )

call GroupEnumUnitsInRange(g, x, y, radius, null)
call PolledWait(0.50)

set a =  CountUnitsInGroup(g)
call DisplayTextToPlayer(p, x, y, I2S(a))

loop
set e = FirstOfGroup(g)
exitwhen e == null

set d = CreateUnit(p, 'h003', x, y, 0.00)
call SetUnitAbilityLevel(d, 'A00A', level)
call IssueTargetOrder(d, &quot;acidbomb&quot;, e)

call PolledWait(0.50)

set e = null

endloop

call DestroyGroup(g)
call DestroyEffect(sfx)
set p = null

endfunction

//===========================================================================
function InitTrig_Infected_Javelin takes nothing returns nothing
set gg_trg_Infected_Javelin = CreateTrigger(  )
call TriggerRegisterAnyUnitEventBJ( gg_trg_Infected_Javelin, EVENT_PLAYER_UNIT_DEATH )
call TriggerAddCondition( gg_trg_Infected_Javelin, Condition( function Trig_Infected_Javelin_Conditions ) )
call TriggerAddAction( gg_trg_Infected_Javelin, function Trig_Infected_Javelin_Actions )
endfunction``````

##### Good Idea™
JASS:
``````    set e = FirstOfGroup(g)
exitwhen e == null``````

-->
JASS:
``````    set e = FirstOfGroup(g)
exitwhen e == null
call GroupRemoveUnit(g,e) // You keep retrieving the same unit over and over, currently.``````

You should learn how to use timers. PolledWait sucks.

Also, first of group loops suck. You can do everything through GroupEnum* when combined with timers.

what is this Ghan? https://enterprise.ghannet.com/ you are totally holding out on us my friend
• Ghan:
Not mine, I just ran the server. They let the domain expire but it was a cool project so I kept it alive there.
• Ghan:
Used to be enterpriserpg.com I think.
• The Helper:
If you go to the world editor tutorials site and click the starcraft link it takes you there
• Ghan:
lol
• Ghan:
I forgot about that alias name. (The full URL still went to the correct site.) That should be fixed.
• Ghan:
Silkroad Forums site really needs help.
• Ghan:
Its software has been out of support since 2017.
• Ghan:
The woes of using custom styles....
• The Helper:
does anyone still use silk road forums?
• Ghan:
It's about as active as here I'd say. Not much going on.
• Wizard:
I think it doesn't help that the silk road game isn't as popular any more I think. The only MMO I play these days is FFXIV like most other people I know.
• The Helper:
I checked a status page for players and it says the game has 500 daily players.
• The Helper:
I cannot believe that site is still going I wonder if Ryoko is involved with it at all would love to talk to him again and see what he is up to
• The Helper:
my oldest daughter failed her driving test today for her license she is 22 and yes I have been driving her everywhere her whole life
• The Helper:
Now they are blaming me on Facebook for her failure LOL I am accepting it because it is my failure I am her driving teacher even though she had certified driving instruction from the best place in town I for some reason cannot teach her how to drive this is frustrating
• jonas:
I didn't get my license until I was 25

• The Helper:
Back in the old days when I was getting a license people were getting them at 16 yrs old and many were getting hardships so they could get them earlier. Almost nobody did not drive when they were able. Nowadays though....
• Ghan:
Why drive when there's Uber Eats?

Diablo 2 Resurrected launching in 9 days.
• The Helper:
Just got a new to me computer hope it will run it
• jonas:
I would buy if it had better modding support than D2, like a small lua script engine or much less hardcoded stuff
• Ghan:
Lots of folks are upset that they aren't supporting mods.
