Annotated Code

Constants

We never want to be population blocked, so make sure we have at least this much headroom.

(defconst min-headroom 3)

Attack as soon as we have a solider. Note that the initial scount also counts for one, so we attack as soon as the army size is two.

(defconst attack-army-size 2)

We'll be building new lumber and mining camps whenever the resources are too far away.

(defconst max-wood-distance 5)
(defconst max-gold-distance 7)

Game rules

Basic build order:

Villager (continuously)
House
Barracks
Militiaman (coninuously)
Mill

From there on:

Houses as needed
Lumber camps as needed
Gold mining camps as needed
New barracks whenever all existing barracks have a militiaman queued up.

(defrule
	(true)
	=>

Taunt the player!

	(chat-to-all "Good day, dear sir!")

We need to do some initial exploring ot find the nearby resources. The scout alone is not enough so also send out one village explorer.

	(set-strategic-number sn-cap-civilian-explorers 1)

Dedicate most soldiers to attack, we want to win by continously raiding the opponent's base, not by defending our own. We do still need some to explore.

	(set-strategic-number sn-percent-attack-soldiers 80)

Devote all our non-explorer villagers to gathering food.

	(set-strategic-number sn-food-gatherer-percentage 100)
	(disable-self))

Our number one rule is to never stop building villagers until the game can handle no more (at 100 pop). The more villagers we have, the more resources we get and the more militiamen we can pump out.

(defrule
	(unit-type-count villager < 100)
	(can-train villager)
	=>
	(train villager))

But always make sure we have enough houses.

(defrule
	(housing-headroom < min-headroom)
	(can-build house)
	=>
	(build house))

As soon as we have the first house we can put some people on wood, which we will need to build our barracks.

(defrule
	(building-type-count house >= 1)
	=>
	(set-strategic-number sn-wood-gatherer-percentage 50)
	(set-strategic-number sn-food-gatherer-percentage 50)
	(disable-self))

Build a barracks as soon as possible. After the first barracks, we want to build a new one whenever we have the resources to train a new militiaman but no available barracks to train at.

(defrule
	(housing-headroom >= min-headroom)
	(can-build barracks)
	(or (building-type-count barracks == 0)
	    (and (can-afford-unit militiaman)
	    	 (not (can-train militiaman))))
	=>
	(build barracks))

After building our first barracks we will need collecting gold to train militiamen.

(defrule
	(building-type-count barracks >= 1)
	=>
	(set-strategic-number sn-wood-gatherer-percentage 40)
	(set-strategic-number sn-food-gatherer-percentage 40)
	(set-strategic-number sn-gold-gatherer-percentage 20)
	(disable-self))

Train militiamen continuously.

(defrule
	(can-train militiaman)
	=>
	(train militiaman))

After our first barracks is up we can focus on our economy for a bit. Build a mill as soon as we find the berries.

(defrule
	(building-type-count barracks >= 1)
	(building-type-count mill == 0)
	(housing-headroom >= min-headroom)
	(resource-found food)
	(can-build mill)
	=>
	(build mill))

Food is the most important resource for building militiamen. Continuously build farms so we can build as many militiamen as possible.

(defrule
	(sheep-and-forage-too-far)
	(can-build farm)
	=>
	(build farm))

Build lumber camps when we find wood or when we have chopped to deep into the forst and the camp is too far off.

(defrule
	(building-type-count mill >= 1)
	(housing-headroom >= min-headroom)
	(or (building-type-count lumber-camp < 1)
		(dropsite-min-distance wood > max-wood-distance))
	(resource-found wood)
	(can-build lumber-camp)
	=>
	(build lumber-camp))

Likewise, build mining camps as needed.

(defrule
	(building-type-count barracks >= 1)
	(housing-headroom >= min-headroom)
	(or (building-type-count mining-camp < 1)
		(dropsite-min-distance gold > max-gold-distance))
	(resource-found gold)
	(can-build mining-camp)
	=>
	(build mining-camp))

When we are ready to attack, taunt the player.

(defrule
	(soldier-count >= attack-army-size)
	=>
	(chat-to-all "It's time for a little paw-paw!")
	(disable-self))

...and actually attack.

(defrule
	(soldier-count >= attack-army-size)
	=>
	(attack-now))

Resigning

We can't recover from a destroyed town center, so if that happens and we have no military units left, resign.

(defrule
	(building-type-count town-center == 0)
	(soldier-count == 0)
	=>
	(chat-to-all "My villagers got bored and started playing MOBA games."))
