[Trigger] Add/remove ability when range

[Lightskin]

How do I achieve this? I want to make that units get an ability whenever they are close to another unit with that ability. Kind of a plague system.

But i'm struggling with the event.

• Unit - A unit comes within 256.00 of No unit

Only options are "No unit" or a variable... what??? where is "any unit" or unit group D:

Any help is appreciated! thanks

Is this will work for you?

• Trigger - Add to (What Trigger) the event (Unit - A unit comes within 256.00 of (Ability-Gaining unit))

Add that when the unit is made through initialization or when created in Unit Action.
If the unit is non-hero, I guess that event can leak.

There is no solution in GUI.

What bear shows works but it leaks because the event will remain even after the unit is dead.
What you would want to do is to create one trigger (with code) per unit. And when a unit dies destroy the entire trigger. You can attach the trigger to a unit easily with a hashtable if you know how to use those.

I think this is a similar/same spell like the one you try to create:
