Can't figure out how to make this trigger

ChaoticEvil	In a map that I'm making, I'm going to have many power generators. When a unit dies in a region centered around one of these power generators I want to change the custom value of that generator. I've been trying to figure out how to do this with just a few triggers, but haven't had any luck with it yet. Could you help me out? Thanks.

If you wanted to, you could assign all the generators to a unit array variable. Then, when u want to check if the dying unit is near a generator you'd have to check all the values, but I think it'd work.
Make one of these triggers for every generator in your map. It would be REALLY inefficient but It would work. Sorry this is all i can think of at the moment.. It's late...

Code:

Event
    Unit - A unit dies.
Condition
    Real Condition -> Distance between (Position of dying unit and Position of Generators[1]) less than or equal to 500
Actions
Unit - Set custom value of Generators[1] to <whatever>

Ummm... surely you can do better than that? Just make one trigger and use a if-then-else action inside a loop to check all the generators stored in the array, or, just use a "pick every unit in unit group" loop, so you don't even need to have the generators in an array. Something like this:

Code:

Events:
    A unit dies.
Conditions:
Actions:
    Set tempGroup = Units of type (Power generator)
    Set tempPoint1 = position of (dying unit)
    Pick every unit in tempGroup and do actions
        loop - actions:
            set tempPoint2 = position of (picked unit)
            If (distance between tempPoint1 and tempPoint2 is less than 500) then set the custom value of (picked unit) to (custom value of (picked unit)) + 1 else do nothing
            custom script:   call RemoveLocation( udg_tempPoint2 )
    custom script:   call RemoveLocation( udg_tempPoint1 )
    custom script:   call DestroyGroup( udg_tempGroup )  [i]//just cleaning out the memory leaks with this[/i]

ChaoticEvil	Anitarf, that trigger looks like it should work really well. I'll try it out. Thanks.
