How to make Damage Area not to affect you alies, youself and buildings?

[joohen]

I made a ability, its passive. % when people attacks you, the guy will blow up, affecting his nearby units. Heres my trigger.

• BackUp
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • ((Triggering unit) has buff Air Support ) Equal to True
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Random integer number between 1 and (25 - ((Level of Air Support for (Triggering unit)) x 5))) Equal to 1
      • Then - Actions
        • Special Effect - Create a special effect at (Position of (Attacking unit)) using war3mapImported\Artillery.mdx
        • Wait 0.50 seconds
        • Special Effect - Create a special effect at (Position of (Attacking unit)) using war3mapImported\NewMassiveEX.mdx
        • Wait 0.20 seconds
        • Unit - Make (Triggering unit) Invulnerable
        • Wait 0.01 seconds
        • Unit - Cause (Triggering unit) to damage circular area after 0.00 seconds of radius 350.00 at (Position of (Attacking unit)), dealing (((Real((Level of Air Support for (Triggering unit)))) x 250.00) + 400.00) damage of attack type Chaos and damage type Demolition
        • Unit - Make (Triggering unit) Vulnerable
      • Else - Actions
        • Do nothing

It hurts me so i made my unit invulnerable, but my units are also affected.... So, how? Or is there any other alternate ways?

You can't.
You need to set a unit group and deal damage to each (Picked unit).

EDIT: A unit is attacked is a useless event.

 

[Amfidamant]

Pick every unit in area around caster, with condition "matching unit belongs to an enemy of (owner of (Triggering unit)).

Then, a "Pick every unit in <this temp group> and Do" loop, with an action "Unit - Cause (Triggering unit) to damage (Picked Unit), dealing (((Real((Level of Air Support for (Triggering unit)))) x 250.00) + 400.00) damage of attack type Chaos and damage type Demolition"

Or something like that. Don't have WE in front of me.

I expect 'a unit takes damage' is what you are looking for.
However, this will trigger even from ranged attacks as well as spell damage.
-This is a specific unit event, so you must add the event through another trigger.
