How to get approached unit?

[stan0033]

When I use teh event "unit comes withing X of gg_Unit" the (triggering unit) is the approaching unit. How to get the approached unit without having trigger for every single approached unit in the map or looping check for evey unit on the map?

Dynamically create a trigger for each approachable unit, map the approachable unit to the trigger using a hashtable, when the trigger fires you can use triggering trigger to get the approached unit. If approached unit is removed (eg as a result of death) one has to both destroy the trigger and the mapping in the hashtable.

There is no native to get the approached unit with that event. This is a frequently asked question.

You can also use some sort of area of effect damage like immolation or phoenix fire combined with a damage detection system.
