event - a unit is attacked

Alright, does anyone know when/how exactly this is triggered? I have been informed that it triggers when a ranged unit initially fires a projectile, not when the projectile hits. It also triggers during the backswing of a melee attack. Do spells trigger this as well? Or is it only physical attacks?

O.k. ... HI!
I have tested this event with a human builder (human player1) and an archer (enemy ai):

EVENT - A unit is attacked
ACTON - Game-Pause

The result was, that the game was already paused when the builder was in range of the archer, who wasn't even shooting, but aiming on the builder!

Hope that helps a bit ;)

spells will not fire it, only physical attacks. And yes you are right, the trigger will fire when the unit "prepares" to attack. if you want to fire a trigger when a unit takes damage, there is the "unit takes damage" event, but note it is only available for a specific unit.

I don't get the reasons blizzard had to make it trigger when the attacking is about to start to attack instead of making it trigger when the attack hits.

to make us able to stop a unit from attacking if he isnt allowed to ^_^

then they should have called it A unit begings attacking or somehting like that

that would've made more sence yes. But ok, name is wrong, but I still need the event sometimes ^^

Basically, I am using it for a custom combat system, and since I can't make it fire with say orb of lightning, then I have to use this to initiate the trigger.

Also, i've seen people saying you can make one of the passive abilities fire a non-passive spell at 100% to check for an attack...does that work?

I suppose you are referring to the abilities orb of slow/orb of lightning(new). Yes, that's what they do, they give the unit that has them a chance to use an active ability on a target upon attacks.

But that ability is kinda wrecked now... Unless you Attack-Move or Attack-Target, the effect wont work, meaning, Auto-Aquire doesn't do jack... :)

Thanks for all the replies.
