How to make this AOE DoT spell?

[Geshishouhu]

I would like to make an AOE DoT spell like the following:
Five units within a certain range of the spell target unit (including the spell target unit or not does not matter) will be infected by the spell, and they will lose HP every second until they die. Upon their death, doom guards will be spawned at those locations

Any idea guys? I do not want to use spells like "Doom" or "Parasite", etc., because they cannot cause damage to spell immune unit. Thanks a lot.

Trigger it. Have some dummy cast some buff that affects magic immune. Then add units into a group, periodic pick and damage, then unit dies - create doom guard at loc.

Thanks. But the problem is what kind of spell can damage spell immune unit?

Remove the classification if the unit is immune then damage it then add classification to it again.

Remove the classification if the unit is immune then damage it then add classification to it again.

Question:
Should I add classification back after the DoT damage is over or add it back after the DoT damage has been casted on the unit?
Thank you.

After it has been casted on the unit to keep from a long DOt spell removing the classification for a long period of time unless you want that effect.

Yeah, you are right. But I am using a loop to pick up units in a group to get the AOE effect, so I am not sure how to set the duration of the DoT for each unit

Edit: I understand what you mean now, lol Thanks a lot, dimf!

You use a counter to tell when to remove the unit from the group.

I do not think its possible to do that or donno how to do it.. my code is like this:

function Trig_aszd1_Actions takes nothing returns nothing 
    local unit caster = GetTriggerUnit()
    local unit target = GetSpellTargetUnit()   
    local integer i = 1
    local location ltarget = GetUnitLoc(target)
    local group g
    local unit u
    local unit dum                                               
    set g = GetUnitsInRangeOfLocAll(800.00, ltarget)
    set u = FirstOfGroup(g) 
    loop
        exitwhen i > 5
        set u = FirstOfGroup(g)  
        call CreateNUnitsAtLoc(1,'n024',GetOwningPlayer(caster),ltarget,bj_UNIT_FACING)
        set dum = bj_lastCreatedUnit
        call UnitApplyTimedLife(dum,'BHwe',1.)
        if (IsUnitEnemy(u,GetOwningPlayer(caster))==true)then
            if (IsUnitType(u, UNIT_TYPE_MAGIC_IMMUNE) != true)then 
                call IssueTargetOrder(dum,"doom",u)
            else
                call UnitRemoveType(u,UNIT_TYPE_MAGIC_IMMUNE)
                call IssueTargetOrder(dum,"doom",u)
                call UnitAddType(u,UNIT_TYPE_MAGIC_IMMUNE)
            endif
        endif
        call GroupRemoveUnit(g,u)
        set i = i + 1
    endloop
    call DestroyGroup(g)
    call RemoveLocation(ltarget)
    set ltarget = null
    set caster = null
    set target = null
    set g = null
    set u = null
    set dum = null
endfunction

Again show your whole trigger when asking for help.
Again never use locations in jass use x/y values.
don't use create unit at location.
don't use == true or != true.
This is also an instant spell so counters are useless.

Here is your triggers with better efficiency

function Trig_aszd1_Actions takes nothing returns nothing 
    local unit caster = GetTriggerUnit()
    local unit target = GetSpellTargetUnit()   
    local integer p = GetPlayerId( GetTriggerPlayer())
    local integer i = 1
    local real x = GetUnitX(target)
    local real y = GetUnitY(target)
    local group g = CreateGroup()
    local unit u
    local unit dum
    call GroupEnumUnitsInRange( g, x, y, 800.00, null)
    loop
        exitwhen i > 5
        set u = FirstOfGroup(g)  
        set dum = CreateUnit( Player( p), 'n024', x, y, 0.00)
        call UnitApplyTimedLife( dum, 'BHwe', 1.00)
        if IsUnitEnemy( u, Player( p))then
            if not IsUnitType( u, UNIT_TYPE_MAGIC_IMMUNE) then 
                call IssueTargetOrder(dum,"doom",u)
            else
                call UnitRemoveType(u,UNIT_TYPE_MAGIC_IMMUNE)
                call IssueTargetOrder(dum,"doom",u)
                call UnitAddType(u,UNIT_TYPE_MAGIC_IMMUNE)
            endif
        endif
        call GroupRemoveUnit( g, u)
        set i = i + 1
    endloop
    call DestroyGroup(g)
    set caster = null
    set target = null
    set g = null
    set u = null
    set dum = null
endfunction

Lessons learned... Thanks. I could only think of this instant spell to achieve what I want.. sad

Edit: actually I want to deal periodic damage in JASS, by using UnitDamageTarget,, but unable to do that

 

[Vinz]

BTW damage that affects immune is Chaos and Universal.. in case you still needed to know.

I believe you can change that in the gameplay constants though.
