I need more information to make a script which will work for you or give you an example of how to do it.
As far as I can see your simple checking the number of units in a region and then making the same amount of Banshees and ghosts in another region. Give me a few minutes.
I got a trigger that first set a variable to the ammount of units of type x in a region and then spawn units for the ammount in a other region
my problem is i got 9 build regions for each player and there 6 players so it will be get very huge
3 spezies 15 buildings 9 regions and this for 6 players
