Triggered ability similar to 'Thorns Aura'

[dashival]

I'm trying to make an ability that is castable on a target enemy unit, and will make that enemy receive a percent damage from on the attacks he makes, sort of like Thorns Aura. I made an ability based on Frost Armor, and it is targetable on enemies. Armor given is 0, the buff is the frost armor buff with different text. I made a trigger that detects when a unit is attacked, and if the attacker has the buff, deal damage to it depending on how much he attacked for.

My question is, can I detect the amount of damage an Attacking Unit inflicts? Or is there some other way to do this spell?

You will need to add to another trigger the event "Unit - A unit takes damage" with (Attacking unit) being your unit with the buff. Next, you just use the function "Event Response - Damage Taken" but beware though as it is a Real number, not an integer.

EDIT : You can run this trigger everytime a unit enters the map.

Enter N Thorn
  Events
    Unit - A unit enters (Entire map)
  Conditions
  Actions
    Trigger - Add to Thorn Damage <gen> the event (Unit - (Entering unit) takes damage)

And for units already in the map at the beginning :

Already there N Thorn
  Events
    Map Initialization
  Conditions
  Actions
    Set Leak_UnitGroup = ((Units in (Entire map)) Matching (((Matching unit) Unit-type) Not Equal to YOUR_HERO)
    Unit Group - Pick every units in Leak_UnitGroup and do actions
      Loop - Actions
        Trigger - Add to Thorn Damage <gen> the event (Unit - (Picked unit) takes damage)
    Custom script:   call DestroyGroup(udg_Leak_UnitGroup)

And the real trigger...

Thorn Damage
  Events
  Conditions
    Dunno if (Attacking unit) applies here... Since it is a damage event.... Anyways try checking if the unit-type of the attacking unit is your hero, 
and if not just create a new trigger that checks [b]everytime[/b] a unit is attacked and if the (attacking unit)'s unit-type is your hero, then set that hero into a variable and use it in this trigger.
  Actions
    Set Damage_Taken = (Damage taken)
    Unit - Cause (Attacking unit) to damage (Triggering unit), dealing Damage_Taken damage of attack type Hero and damage type Normal

That is just a basic view of the trigger. You must modify it according to your map and skills... and stuff.

Have a nice day !

Would this work, by itself? (I just realized that the life will be set extremely low, but does this work?)

trap
    Events
        Unit - A unit Is attacked
    Conditions
        ((Attacking unit) has buff Frost Armor) Equal to True
    Actions
        Unit - Set life of (Attacking unit) to ((Damage taken) x 0.10)

        [B]Unit - Set life of (Attacking unit) to ((Damage taken) x 0.10)[/B]

(Damage Taken) ONLY WORKS with the "Takes Damage" event. But that event can only be "added" to other triggers, like I did above.
