Skaven Settlements: AI Use Under-Cities

The Skaven AI don't seem to make good use of any under-cities they may have. This mod detects when an under-city is established by an AI faction, and gives them an under-city template from a list I've provided them, meaning they're on-par with what a player would use. All vanilla under-city buildings are used within those templates. The templates are selected semi-randomly after taking contextual information into account, such as diplomatic relations, global food income, and settlement income.

Some templates are considered "special" since they make use of destructive buildings such as the Plague Cauldron and Doomsphere. You can disable any under-buildings and adjust the chances the AI will use the "special" buildings with the Mod Configuration Tool (MCT) as well.

I recommend my other mod, Skaven Settlements: Expand the Under-Empire to greatly increase the number of under-cities they get. Without it they're likely to only have a handful throughout the game.

The AI also periodically updates their under-cities to make sure they're still relevant to their current situation. Hopefully this will help the Skaven feel more like The Menace Below they should be.

This mod is multiplayer compatible.

I've also created an API with the mod that allows other mod authors to add templates and remove them from this system. You'll find that here. It also allows them to specify the conditions under which the template should be added to the selection pool for a given under-city. The system itself will ensure that a building does not put the AI faction into a low-income or negative food state, before it is built, if that building data was supplied when it was added to the system.

Let me know if you have any questions, suggestions, or feedback.
