[Trigger] Calculating Vision of a Unit

[En_Fuego]

Okay, so I had an idea for a hero. The spell is called "Vision Hack" and is meant to respond to the units ultimate "Maphack" which allows that unit to see the entire map. Now, the only problem is that I'm trying to make it so that "Vision Hack" damages every enemy hero that is visible to the casting player.

What I have so far works, minus the hero having to be in vision:

• Vision Hack
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Vision Hack (C)
  • Actions
    • Unit Group - Pick every unit in (Units within 1000000000.00 of (Position of (Casting unit)) matching (((Picked unit) belongs to an enemy of (Owner of (Casting unit))) Equal to True)) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • ((Picked unit) is A Hero) Equal to True
          • Then - Actions
            • Unit - Cause (Casting unit) to damage (Picked unit), dealing (Real((Intelligence of (Casting unit) (Exclude bonuses)))) damage of attack type Spells and damage type Normal
          • Else - Actions
            • Do nothing

I dont think that there is a way to check if a hero is inside the vision range, but what I would do is pick every unit inside the hero's vision range.

And also, put this before you pick every unit within 1000000000

• Custom Script: set bj_wantDestroyGroup = true

It prevents leaks.

Meh, i imagine that there is a sight range thing in JASS but not sure. It seems likely. And there is a circular radius.

How did you fix it?

Good problem solving!
