Allying with an AI player automatically causes that AI player to ally with you. AI players not allied with you ally with each other. You can change alliances at any time (the script checks this every 10 seconds), but the idea is meant for the human to choose the teams near the beginning of the game. Also, the AI players send units to help their allies in the same way as they send units to defend their own.
Known problems:
1) the AI players sometimes attack allies' walls; remedy: demolish/rebuild that wall section.
2) an AI team sent to attack a structure sometimes continues their mission if an alliance is made during their mission.
This is my first post, so here is some relevant info about myself:
I first played Warzone 2100 on the Playstation1 (now I have it on my PC).
I have written scenarios for Red Alert Yuri's Revenge (my pseudonym there is "Clever Boy"); Warzone2100 seems less bug-ridden for scripters. I want to make something of the separate script file for each AI player.
