Nearest unit

Thunder_Eye	Can someone tell me an easy way to check what unit within 500 (or something) is nearest the caster? I know this has been asked before but I dont have time to search it up.

Vexorian	Get the unit whose distance to the caster is the minimum of all the distances you get

Thunder_Eye	So.. how would I do that in trigger? would I have to loop it like first 10, 20, 30, 40 etc. or is there any easier way?

PCPharaoh	Pick every unit in 500 of caster, and calculate their distance to the caster. Whoever has the shortest distance is your unit.

Well I dont get how to do the check, I'll need a variable right?

This works?

Trigger:

Unit Group - Pick every unit in (Units within 1000.00 of (Position of Peasant 0000 <gen>) matching (((Matching unit) Not equal to Peasant 0000 <gen>) and (((Matching unit) is dead) Equal to False))) and do (Actions)

Loop - Actions

If (All Conditions are True) then do (Then Actions) else do (Else Actions)

If - Conditions

Unit Equal to No unit

Then - Actions

Set Unit = (Picked unit)

Else - Actions

If (All Conditions are True) then do (Then Actions) else do (Else Actions)

If - Conditions

(Distance between (Position of Peasant 0000 <gen>) and (Position of (Picked unit))) Less than (Distance between (Position of Peasant 0000 <gen>) and (Position of Unit))

Then - Actions

Set Unit = (Picked unit)

Else - Actions

gonna test it now
and YES I know it leaks alot.

EDIT: Well it works sometimes :S

EDIT2: Ok its fixed, had to check if the picked unit was dead or not, thx for the help.

PCPharaoh	That seems like it would work to me. When exactly does it work and not work? Opps. Posted before your edit2. Nevermind. :P
