[Help] AoE spell trigger.

[Zonagle]

So, what I'm after is this.

The unit casts the ability, he gains some holy aura around him(SFX) it lasts 15 seconds. During those 15 seconds, any unit that comes within say, 500 of the hero, is struck with a holy bolt at 3 second intervals, creating a special effect at the location of the struck unit. It's not a channel spell, so the hero would be able to move around while it was active.

Any help would be more than welcome!

Edit: I'd assume you'd need to have two spells, and two triggers. The first spell would activate the first trigger, which would create a dummy unit, who'd then cast the spell at any enemy within 500, checking every 3 seconds. I'm still not really sure how to trigger this.

Firstly, make the ability based off "Berserk" or "Unholy Fever"(I forgot what it was called)
Set everything to 0 so that you gain no bonus damage or attack speed from the ability.
Set the duration to 15 as you wanted.
Now go make a new buff based off whichever ability you chose.
Just change the effects of the buff and the description as well.
Go back to the ability and replace the default buff with the new buff you made.

Holy Bolt

Events
   Every 3.00 seconds of game time
Conditions
Actions
   Set UnitGroup1 = Units in entire map matching condition matching unit has buff Holy Aura equal to true
   Unit Group - Pick every unit in UnitGroup1 and do actions
      -Loop
         Set Caster = Picked Unit
         Set Casterloc = Position of Picked Unit
         Set UnitGroup2 = Units within 500 range of Caster matching condition matching unit is alive equal to true and matching unit belongs to an ally of Caster equal to false
         Unit Group - Pick every unit in UnitGroup2 and do actions
            -Loop
               Unit - Create 1 Dummy at Casterloc facing Picked Unit
               Unit - Add a 3 second generic expiration timer to last created unit
               Unit - Add Holy Bolt(dummy) to last created unit
               Unit - Order last created unit to Holy Bolt picked unit
         Custom Script : call DestroyGroup(udg_UnitGroup2)
         Custom Script : call RemoveLocation(udg_Casterloc)
   Custom Script : call DestroyGroup(udg_UnitGroup1)

Should be something like that..
I wasn't too sure about your "special effect at the location of the struck unit"

cant u just let a dummy unit cast starfall with holy light strikes then u got the strikes not on the same moment and the idea is then to move instantly the unit constantly o nthe hero so create dummy none.mdl
[ i dont know if move instant cancels the ability]

What do you mean, not too sure? As in, not sure what I meant, or not sure how to go about it?

When a unit is struck by the Holy Strike/blast/whatever, I wanted to create a spell graphic above their head, of the spell Holy Light.

Edit: Would it work, to have a trigger activate that trigger you made? Eg.

Event - A unit begins the effect of an ability
Condition - Ability = berserk
Action - Turn on your trigger.

Otherwise, the timing might mess up, yeah? It counts 3 seconds all the time. So if it was going 1 2 3, 1 2 3, 1 2 3, and you cast the ability at say, 2 seconds, it'd be slightly off. Then obviously you'd need to add a way for your trigger to turn off after 15 seconds. Would a buff check work? In action, If unit has buff - Holy Nova, do whatever, else turn off this trigger. Also, do we need the dummy with this trigger? Couldn't we just have the caster deal damage directly to the enemies around him?

Updating with triggers.

I realize I check that the units within 1000 yards are alive and not an ally, but hey, as far as I can tell, this trigger functions exactly like I wanted it to. Thanks for all your help, lh2705.
