Unit comes within range of a unit type

[Fluff]

I need an event for GUI or JASS that detects when a unit comes within range of any unit of a particular type (or any unit in a unit group).

I need something like:

Event - A unit comes within 100 of *a barracks*
Conditions - Trigger unit is equal to footman
Actions
....

The other option would be if a unit comes within 100 of any unit within a "barracks" unit group, which contains all the barracks on the map. Or, I could maybe detect when a unit gets a "barracks aura" and then I know its close to a barracks.

Any thoughts?

So the problem i assume your having is that using the "Event - A unit comes within 100 of ______" where u cannot use variables or anything except for preplaced units in the blank. I had that problem a while ago, and the way around it is to have the action Trigger - add event to trigger.

• Trigger - Add to (This trigger) the event (Unit - A unit comes within 256.00 of (Picked unit))

replace the this trigger and picked units, this is the only way in GUI that i know how to use this event on nonpregenerated units

That is helpful for a possible work-around, but my issue is that I can't use a "unit of type". The trigger is set up so I can only use single units.

I was thinking you could add that event to the barracks that were being made, then have a condition already on the trigger ur adding the action to of something like this

• (Unit-type of (Entering unit)) Equal to Footman

So when the footman gets within xxx of the building, not the building gets within xxx of the footman

I think there is no way to do it, or maybe there is one in JASS, but I don't know JASS, but you can do it like that: And add 1 more action for every unit:

• Events:
• Time - Every 0.10 seconds of game time
• Actions:
• Unit Group - Pick every unit in (Units within 100.00 of (Position of Your Unit) Matching Unit Type of Picked Unit Equal to YOUR UNIT) and do (Actions)
  • Loop - Actions
    • Your Actions

I didn't try this out, but maybe it works!

That will work, however a new problem is caused with leaks and having a trigger execute 600 times a minute will probably cause much lag. I would keep looking for an alternate way before resorting to this. I know i experienced this with a fps type map that changed camera every .10 seconds when more than 4 people were in the game.. Just a thought

Fluff, take the same approach as done with generic damage events.

Whenever a unit enters the map of the specific type, attach an enter range trigger to the unit type. When it dies, destroy said trigger.
