Do you have access to the latest Chaos Daemons mod?
I have created a new function there, called SetSquadLimitsBasedOnStrategy(iStrategy).
See in strategies/daemonsbuildbasestrategy.ai
I couldn't find it in that file.
This is for the AI to check if it should attack the enemy with the army it has currently deployed.
I thought it meant not to build that thing until the army had reached a minimum strength, for example
{ 1, 200, 200, 700, 1, "Building", "eldar_soul_shrine" },
would mean don't build soul shrine before our army strength reaches 700. I could be wrong though.
Edit: I just deleted my build plan and the ai played the same way, are you sure the ai uses these?
