Community Patch: AI

  • AI logic regarding Deals made variable - value and demand for resources based on supply, proximity of player, relative strength and happiness.
  • AI trained to better engage in naval warfare - more likely to land an army on the shore before attacking (as opposed to a pure naval operation). Will send more boats, and will be more likely to simply engage in a naval bombard before using land troops.
  • AI prioritizes protecting embarked troops, avoiding unnecessary embarkation, and staying out of ranged fire if possible.
  • AI less likely to send units alone to assault a city.
  • AI now prioritizes targeting units that are dug-in, so as to force them to retreat or destroy them.
  • AI more aggressive towards human players (based on difficulty).
  • AI randomness regarding movement and tactical decisions reduced
  • AI settler placement, including turn 0 settling, optimized to focus on strategic locations rather than purely resource-based locations.
  • AI military targeting considers pathfinding as well as mobility around a target when evaluating how difficult a city is to capture.
  • AI warmonger values dynamic, based on more than just conquest - religion, ideology, past history, WC decisions, and co-op wars all play a part in how much warmonger is earned from aggression.
  • WC logic reevaluated to make the AI more likely to form coalitions of similar interests and to push through beneficial resolutions.
  • Tactical AI optimized to encourage moving-shooting and proper positioning for ranged units.
  • AI targeting and positioning for melee units optimized.
  • AI trained to spend gold on units and buildings it desires.
  • More nuanced diplomacy with regards to warmonger and other values.
  • AI more attuned to victory conditions and proper use of Great People.
  • AI flavors for leader personalities optimized based on CEP's changes.
  • AI army and navy size/composition optimized.
  • AI missionary and prophet logic optimized to reduce spam.
  • AI trained to effectively understand and use all new gameplay systems added by the Community Patch.
  • AI has multiple 'tourism defeat' announcements based on era. No more 'blue jeans' in the Classical period!
  • AI more intelligent about faith purchases, and should manage its missionaries and prophets much, much better (should build faith buildings and buy great people, etc. much, much more often)
  • Spy-related diplomacy messages can now spawn only once every 40 turns (limits spam)
  • Flavors optimized for new policies and ideologies
  • Adjusted Deal AI to trade resources for gold more often
  • AI will more intelligently use trade routes to combat poverty, famine, and illiteracy
  • Improved AI belief choice algorithms
  • AI defense of CSs during rebellion events optimized
  • AI workers won't scatter across the map to do tasks as often (Whoward's 'Local Workers' mod)
  • AI more intelligently builds great person improvements (removed ninaroku'h hardcoded stuff, added flavor-based system)
  • AI much more intelligent regarding belief choices (randomization removed)
  • Flavor text regarding AI victory competitiveness added
  • AI will warn player when they are sure that they and the player are approaching the same victory condition. This is purely for flavor, and to help the player figure out what the AI is doing in the late game.
  • AI less likely to send ranged units alone to assault a city.
  • AI better understands the danger of water, and the importance of staying on land if possible.
  • AI more likely to respond to assaults on their land if they are also engaged in an offensive.
  • AI better able to reposition bombers to attack.
  • AI Naval invasions optimized to have a better mix of damage-dealing ships.
  • AI Armies more flexible in size and composition.
  • AI more likely to disengage if losing a fight.
  • AI will no longer send prophets and missionaries to cities that they are at war with
  • AI trained to better engage in naval warfare - more likely to land an army on the shore before attacking (as opposed to a pure naval operation). Will send more boats, and will be more likely to simply engage in a naval bombard before using land troops.
  • AI prioritizes protecting embarked troops, avoiding unnecessary embarkation, and staying out of ranged fire if possible.
  • AI values luxuries based on the quantity of happiness they can receive from them
  • AI values lump gold over gold per turn slightly.

Custom versions of two popular mods created to work alongside the CBP:

  • Over 40 new functions, and over 50 new secondary tables, all of which add new abilities and actions to buildings, policies, units, and more.
  • Additional yields, (YIELD_GOLDEN_AGE, etc.) added to allow buildings, policies, and more to add different types of values.
  • DLL changes optimized to limit performance impact.

LUA

Happiness Happiness System completely revised. See below.

Luxuries: Luxuries now grant their bonuses as a factor of total empire population. The higher your pop, the more happiness your luxuries provide. This makes luxuries less vital early on, as +1/+2 isn't as big of a deal, yet it does not punish tall or wide strategies because the focus is on overall population, not # of cities.

National Happiness: Rather than having a flat penalty at -1 unhappiness and below, unhappiness penalties scale with each point of unhappiness below zero, up to a certain maximum threshold. This scale affects all yields, though in varying amounts. This makes expansion/unhappiness less binary, and allows players to be slightly unhappy without catastrophic problems.

City Happiness: The big one. City happiness is now no longer affected directly by the # of citizens in a city. Instead, happiness is based on a set of functions that look at the variables below. Overall, population is still king, however per-city unhappiness is a bit easier to manage (and tailor to certain playstyles), whereas the penalty per # of cities is dramatically reduced. This makes Tall and Wide gameplay equally feasible, so long as your empire is well-managed.

The yield-based functions combine your city's yields, dividing this value by your city's population. This value is then compared to the rate value per citizen as a global average of all city yields per pop. If the rate value per citizen is higher than your city's yields (i.e. you are not producing as much as the rate value expects), the difference between the two is multiplied by the per-citizen unhappiness value and the unhappiness is generated. In other words, if your cities are significantly behind other global cities in yields per pop, the difference will be converted into unhappiness.

Keep in mind that, since the unhappiness per citizen element of the game was removed, you are almost always going to have one or more of the following 'problems' in your cities. This is necessary in order to keep happiness from skyrocketing up to 100+, and is fairly realistic. No city is perfect, so don't fret if you have poverty or illiteracy in your cities.

Poverty: This looks at a city's food and gold yields. If these yields do not exceed the rate criteria, your city has some element of poverty. This is largely inevitable in all but the wealthiest cities or most fertile cities.

Illiteracy: This looks at a city's culture and science yields. If these yields do not exceed the rate criteria, your city has some element of illiteracy. This is largely inevitable in all but the smartest or most wonder-heavy cities.

Religious tension: This looks at a city's majority religion, and compares it to the number of citizens that are not part of that religion. If that value exceeds the rate value of the function, you will have some religious strife (note: as I stated earlier, this does not mean that religious minorities = unhappiness, but rather that a mix of religions in a city runs a higher risk of creating religious unrest. That's all. Seriously.). This is largely inevitable in most large cities, but should never be a major source of unhappiness. This value also decreases gradually as the game progresses. You can reduce this value further by building more faith-producing buildings in the city (high faith production has the ability to subtract from a city's minority population), or simply converting people to your one, true faith.

City connections (Isolation): This is simple. Blockades or a lack of a city connection will generate unhappiness based on a rate per citizen value. Should only be a problem if you are besieged from the sea, your routes are pillaged and/or you haven't connected your cities together.

Pillaged tiles: Similar to city connections, this function will generate unhappiness based on a rate per citizen value which looks at the number of pillaged tiles. The more pillaged tiles there are, the higher this unhappiness. No one likes looking at burning fields.

Starvation: This one can be fatal, so be careful. If a city is starving, this function looks at the value of that starvation (i.e. the negative value of food being consumed) and compares that to the rate value of the function. Don't starve people.

Disorder: This function looks at your cities defensive capabilities and your city's garrison. Taking defense as a 'yield' (i.e. the defense produced by defensive structures) and increasing it by a factor of your city's garrison), this value is then divided by your population. If lower than the expected rate per citizen, the difference is multiplied by the unhappiness per citizen rate.

Specialists also generate unhappiness (1 point per 2 specialists in a city).

  • Unhappiness reduction on buildings based on city population. Explanation: formerly, a building’s unhappiness reduction was 1 * -100 (so -100), where 1 was the variable in the XML. Now, the function is 1 * (x * -1), where x is the city’s population. This means that buildings become more useful the bigger you city, however it is harder and harder to deal with thresholds as cities grow, so there is now a trade-off (in other words, instead of ICS being a viable strategy, you now have to be careful about overextending your ability to deal with small city unhappiness, as bigger cities get more bang for their buck from unhappiness-reduction buildings). This also makes these buildings less immediately impactful, thus making unhappiness a more important force overall, particularly in the early game.

Other: Added Process 'Arts,' which allows conversion of Production to Culture (at Drama).
