I'm curently using Expansion Zerg Campaign Insane, and it works fine.

But.. I'm using the same thing for Terran and it's awful! Expansion Terran Campaign Insane.
The comp will use only 4 SCV's to build, will not build anymore scv's, will not build a refinery and mine form it, he will build a factory (which i found out when using this a.i the comp starts with ore and gas). The zerg computer just destroys the terran with a breeze.

Any help to why the comp is not building or a better A.i Script for me to use? Thanks.

Keep in mind, i never edited any of the units prices, or disabled scvs. The minerals and gas are spaced out properly from the CC, so it wont mess up the A.I.

If you are using SCM Draft, then go to: Scenario > Map Description. From there, set which race you want the computer player to play.

For example, if you want player 3 computer to play as terran, then set the race to terran. After that, you can set the AI for the computer to "Expansion Terran Campaign Insane"

that's already been done. I forgot to mention that.. Any other ideas?

if you want to, can you PM me the map so I can take a look at it?

It was reported that certain terrain formations can hinder a computer's building plans. Try making the terrain very open and plain for testing purposes.
