Custom Races

From what I've heard, AMAI supports custom races. However my races are quite unique, for example they build units and then use an ability with the unit on a building to get lumber. Another race sells items to get resources. Is there a way to make AMAI do this with the developers version or is it doomed to fail?

You could get AMAI to build your new races units and structures but it would get confused on how to collect resources. You would have to use triggers or change the core Ai script of AMAI or have it cheat. There may still be a problem that AMAI will still call the standard resource collection system which might conflict in your new system in unknown ways (or it might not)

So its not impossible as my mod war2 2nd generation is an example of combining triggers and gameplay mechanics with script AI but it will take a lot of your time to make the AI perfect.
