Unit within range of ...

[Immolation]

How I refer to other unit of this event?
(Triggering Unit) refers to the unit entering in range, I want to refer to the other unit.

Darthfett wrote a system just for the purpose of getting the 'other' unit in the event. vJass, however. Nothing GUI.

Could you be more specific? Seems like an easy problem to me.

We'll use Footman and Rifleman..
Footman = Entering unit.
You want to know about the Rifleman.

I'm pretty sure if you're using a slice of code like that (which requires "Specific Unit Event", if I'm not mistaken), you should just be able to plug Rifleman into a Unit Variable.

If this isn't localized, there's always "Every 0.05 seconds of game time"
"Wait for Condition - Footman comes within X of Rifleman..."
