How do i code this?

[NetherHawk]

Ok i have coded an ability that creates an illusion at every enemy hero and the illusion will keep attacking that specific enemy hero.

i have a function that groups all these enemy heroes and sets them to a variable -- Hero[A] where a is an integer variable.

once this is done, a dummy is spawned to create an illusion of the caster.

Hence i have another trigger that registers when a unit is summoned having the illusion buff. The Illusion is then moved to the Hero[A] position. How do i set the target hero for this summoned illusion.

Ive tried every time the trigger is registered to set A = A - 1, however this way only 1 hero is attacked by the illusion, the rest are moved to the centre of the map.

scope Haunt initializer Init

//Objects Used:
// 'A045' = Haunt (Spectre : Mercurial)
// 'A046' = Reality (Spectre : Mercurial)
// 'A047' = Haunt Effect
// 'B028' = Haunt Illusion Buff

sorry i found a solution, i created a struct which contains the target unit every time a suitable filter unit is found and attach it to an individual trigger. Mods can delete this thread.
