Illusion-based ability

[defskull]

I think I had already opened this topic before and no accurate solution is found.
So, maybe our professionals here have gained much more knowledge and new technology/tricks (maybe?) have been discovered to tackle this one problem

How to register the unit that is produced by Illusion-based ability ?
Let's say a Mirror Image spell which summons 3 Illusions upon cast.
How do I get/catch/register those 3 newly-spawned illusion to be saved in a Variable ?

Many people suggested to catch them via picking all units within cast-point location and detect them via IsIllusion checking condition, but this one can't be used as other Illusion-related spells could exist in that game, and potentially clash with the Spell itself - for example, I want to register only those illusions that are summoned from the Spell, and if I picked them all inside the range, it includes other illusions (spawns from other Spell(s) as well), making the spell collides with others.

The easiest visualization for the example above is Phantom Lancer from DotA2, Doppelganger - where it picks all illusions, regardless of the source of the illusions spawned.

Anyone manage to find the solution to this problem yet ?
Or at least a different approach.

Or is it just impossible ? :'(

Does the Mirror image units have the mirror image buff?
Then you could save the hero, do a "get all units near tempPoint1" matching:
Unit != our hero
unit type of picked unit == unit type of (our hero)
unit belong to player(our hero)
unit has buff (mirror image)

It should work since other illusions will not be made with the Mirror image buff and it will be MUI as you do check the player owner of the illusion.

It's MPI, not MUI, right ?
Need it MUI though.

Also, does Illusion spawned from Mirror Image has buff ???

I assume they are caught by the "Unit enters <region>" event.
If so, you can use that.

Got an idea, would test it out and report back to this thread, combined with LorDz approach.

I think this will work.
Another approach is to test with "A unit is summoned" so that you can relate the illusion to the caster if your ability is based on Mirror Image.
