request : group creep

[War3shade]

Someone cna make this for me?r just give me an idea an how doing it
I include a creeps spawn system in my map that spawns creeps at a point and randomly patrol in an area.What I'd like is that if,a creep come within another creep,they create a group (a unit-group) which patrol together and can add more creep in the group.But groups of different races aren't possible, I mean if a bandit encounter a mu'gul they don't team

It would be possible by detecting every X second if a unit is near another...but It will cause big lag having a trigger that fire every 1 Seconds

I heard that using timer with 1 second will fix this.Throught Im not sure of that

Can't you use the unit get's in range event and the trigger add event trick for that one?

Everytime a unit enters the map have them added as a event to the trigger.

Yes but using a timer that chech every second would be easier,no?
