Ok what the regular insane script does is: build 1 main base with all advanced structures and a few expansions. But when you destroy the main base, they won't rebuilt it.

What i want is that once their main base is destroyed (or their command center), then they must built a new main base, with all structures and advanced structures. If they start building 3 different main bases on different locations, this is ok as well.

I tried several things for creating 2 main bases, but it just DONT work.
such as:
if: player1 brings 0 command center to location X (original location for AI, main base)
then: run script AI at location Y

You can only run one AI script at a time, and the only AI script that I got working to its fullest potential (and that is rebuilding the primary city), was Campaign AI.

If you use two computers with the same colour, you could run Campaign and Insane AI and they would look similar. And I suppose using the Shared Minerals System, they would have equivilant resources.

I suppose you mean campaign insane AI?

The problem is there are a few allied players, so there are little enemy players left + I would like a real though enemy player. Did you have any specific settings to get the computer player to rebuilt the main base?

Try the custom level ai

I want the AI script to work for a while.. so for both custom AI & insane AI, how much money should I give? About 30.000 or is it better to give about 7.000 and let them mine for themselves if they have resource shortage?

The Insane AIs are set up to have 3000 of each resource, and the Custom AIs are the normal Melee AIs, so they don't need any money.
