Reactive Passives

This has been bugging me for a bit, and is a simple question (And I have yet to get an answer)

What is the difference between a script that detects the attacker has an ability, and a script that detects if the attacked unit has an ability?

And Good Example of the first is this one By Paskovich: http://hiveworkshop.com/forums/showpost.php?p=271785&postcount=5

I Tried converting this script to detect if the Attacked unit has a buff (Can be found here: http://hiveworkshop.com/forums/showpost.php?p=285518&postcount=6 (Second script))
And It wouldn't work. Similarly, paskovich told me this:

I recognise your second script, the original was written by me. It detects if the unit with an ability damages another one (like Critical Strike), but not when the unit is damaged (like Evasion, or Thorns Aura, etc...).

My question is simple. What is the difference between the two? Shouldn't it just require you to change Everything designating "get from attacker" to "get from Attacked unit"?

Please try to be more clear. You're asking what's the difference between attacker and attacked unit, or what?

 

[paskovich]

Take a unit with Evasion. When does the evasion effect go off? When the unit is attacked.
Now what's up with Critical strike? The effect goes off when the unit attacks.

What is so hard to understand about this?

In my attack-detection engine, the trigger detects if the unit with an ability attacks a unit. Like Critical Strike.
If you would want to recreate an artificial Evasion, it would require an other script.

Just use a generic attackdetect with if-statements to sort out the various effects, so that you don't need it implemented once per ability that uses it. You shouldn't have any direct problems then.

Eg:

function AnyUnitTakesDamage takes nothing returns nothing
    if GetUnitAbilityLevel( GetEventDamageSource(), 'A002' ) > 0 then
    elseif GetUnitAbilityLevel( GetTriggerUnit(), 'A01B' ) > 0 then
    (etc)
    endif
endfunction

The only proble with that, Purple, is that it detects any type of damage. But in other cases, yes, it's useful.

I actually meant yours or a similar one, just with no specific condition.

However, if you do it right, a general damage detector is better anyways.

Ahh! ok ok, I misunderstood what you wrote. :S
You're right then!
