Vision Activated Triggers

[Seavalan Legend]

I have been exploring the editor, and one thing I am trying to figure out is have a trigger get activated by having vision on an area/region. Thank you in advance for the help!

No AFAIK but you can activate when a unit comes withing range of something

Really? That is unfortunate, as such a trigger seems essential for map making. I guess I will have to redo a part of my map. Thanks for the answer!

True, there is no such function. But there are only a few ways that you can gain visibility of an area at all:

- Unit in range (provides sight to player and all Shared Vision allies)
- Visibility Modifier
- Reveal skill cast
- Unit attacks from fog
Maybe a few I'm forgetting?

Anyways, these events are easily detectable. So you can probably put together something for what you need

there is a way to do it actually, give me a bit and i'll give you a map, the triggers will be a little complex, nothing major though

EDIT:
something along the lines of this i'd assume, you need to create a dummy unit at the position of your units target, if that dummy unit is created inside a region have it then check if the dummy unit is a certain distance from you hero, if it is say 200 from your unit then have it run a trigger

• when you issue an order
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to Sylvanas Windrunner
  • Actions
    • Set targetedpoint = (Target point of issued order)
    • Unit - Create 1 Dummy Unit for (Triggering player) at targetedpoint facing Default building facing degrees
    • Set Dummyunit = (Last created unit)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Region 000 <gen> contains Dummyunit) Equal to True
      • Then - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Dummyunit is in (Units within 200.00 of Yourunitpos)) Equal to True
          • Then - Actions
            • Quest - Display to (All players) the Quest Update message: Works
          • Else - Actions
      • Else - Actions
        • Do nothing

  • Actions
    • Game - Display to (All players) the text: Player 1 can see th...

Turn the trigger off with Trigger - turn off (this trigger)
if you only want it to run once.
