Stellaris, carnet des développeurs n°232 et 233 : Mise à jour 3.2 "Herbert" et Aquatics, Équilibrage, Performance et notes de la mise à jour.
Bonjour à tous, aujourd’hui nous parlerons des changements du patch 3.2 “Herbert” (d’après l’auteur Franck Herbert) qui accompagne l’extension Aquatics. Ces derniers sortiront lundi 22/11. En fin de carnet vous retrouverez comme à l’habitude les notes de la mise à jour.

Équilibrage :

- Architecture Fonctionnelle et Constructobot, réduction du nombre d’emplacement de bâtiment de +2 vers +1,
- Paradis Agraire, +1 emplacement de bâtiment tous les 4 quartiers agricoles,
- Réduction de l'entretien des flottes pour les amiraux clones de 5/10/20% selon les décisions,
- Le site archéologique Ruines de Shallash ne donnera plus une quantité d’unité identique à si vous gagner face à la crise de fin de jeu,
- Il n’est plus possible d’utiliser des armes tueuses de planètes sur des primitifs à l’intérieur de vos frontières si vous n’avez pas les bonnes politiques d'interférences,
- Les populations assimilées à du bétail auront 10% de pouvoir politique en moins,
- De nombreuses anomalies donnant un dépôt de +3 de recherche sociétales ont été modifiées pour plus de variété,
- Les Empire déchus utiliseront les arbres de traditions (mais pas les ascensions),
- Plusieurs technologies de productivité n’auront plus de bénéfices cachés et leurs effets ne s'appliqueront qu’aux emplois primaires de la ressources en question,
- Les populations de ruches “dénervées” ne pourront plus occuper des postes pour drones complexes,
- Le nombre d’emplois des Arcologies de loisir a été réduit pour les aligner avec ceux des autres,
- Les canons à Ions ne sont plus gratuits à l'entretien et coûteront 8 d’énergie.

Parlons maintenant des Ruches Nécrophages :

- Pénalité d’assemblage des populations à -50% (de -75%),
- Différents modificateurs de population ne s’appliqueront plus (en raison du statut de Ruche de l’empire),
- La réduction d'entretien en énergie des populations organiques photosynthétique s’appliquera,
- Les essaims dévorant Nécrophage commenceront avec plus d’infrastructure pour compenser leur manque de chambre d’élévation.

À propos du changement sur Architecture Fonctionnelle. Nous sommes au courant que les emplacements de bâtiments supplémentaires sont l’argument n°1 pour prendre ce civisme mais à cause de cela ce dernier est surreprésenté dans le jeu (y compris après l’enthousiasme post sortie). L’équilibrage n'était pas la priorité sur cette mise à jour mais nous continuons de réaliser différents changements à chaque version.

Et maintenant je laisse ma place à Caligula Caesar à propos de l’amélioration des performances et de la moddabilité (NdT : ci dessous une synthèse, pour le texte complet je vous invite à cliquer sur la source).

Les Scripts :

Les développeurs ont eu quelques soucis pour mesurer l’impact de nouveaux scripts sur les performances du jeu. Heureusement, Moah a réalisé d'importants progrès sur un outil venant d’EU4 et le travail a été finalisé par l’équipe Custode.
Ainsi Caligula a pu faire tourner le jeu avec que des IAs pour voir comment les scripts affectent les performances (NdT : des logs sur ces dernières sont disponibles en sources). A terme cet outil sera disponible aux moddeurs. Actuellement cependant il ne tourne que sur une version développeur du jeu et le ralentit considérablement (50%). Les développeurs pensent d'abord corriger la perte de performance et créer un système d'activation ou non de l’outil en jeu avant de nous le proposer.

Les Gains faciles :

L’outil en place, il a été très facile d’identifier les scripts peu utiles qui consommaient pourtant d’importantes ressources de par leur nature ou leur répétition (jusqu’à plusieurs fois par jour de jeu). Une fois l’identification faite, les corrections peuvent venir de plusieurs endroits.
D’abord du jeu en se posant la question si ce script est nécessaire (pas besoin de lancer des scripts relatifs aux populations sur des planètes non colonisables), si les valeurs obtenues ne peuvent pas être misent en cache ou si il est vraiment nécessaire de vérifier une valeur 3 fois par jour. Du côté de la structure du script, nombreux sont ceux qui ont pu être optimiser en changeant quelques options de déclenchement ou en améliorant leur cible afin de réduire le nombre d'éléments à vérifier (d’abord voir si il y a du chômage sur une planète avant de compter si il y a plus que 3 populations au chômage par exemple ou encore vérifier si l’empire n’est pas de conscience collective avant de lancer les événements concernant la criminalité).

Vers plus d’analyse :

Une fois le nettoyage effectué et les scripts les plus évident améliorés il est devenu plus difficile de voir quel script optimiser. C’est là qu’entre en jeu un tableau de données :

Les valeurs montrées sont celles après optimisation.
Cela permet de se poser des questions plus globales et d’optimiser plusieurs scripts à la fois lorsqu’ils sont liés les uns aux autres. Ce fut le cas pour la production des ressources, l’attribution des emplois aux populations et la création des factions.

Au delà :

Les résultats de ces changements sont très bons et le jeu est un peu plus rapide en fin de partie. Cependant, il n’y a pas que les scripts qui ralentissent le jeu. L’interface utilisateur est ainsi un autre sujet d’importance en particulier en fin de partie (marché aux esclaves, le tableau des espèces, etc).

NdT : La suite est à propos des mods avec plein de nouvelles fonctionnalités mais encore une fois je vous laisse aller en sources si vous êtes curieux.

La mise à jour 3.2 “Herbert” avec Aquatics :


Il y a eu un Q&A jeudi dernier et vous trouverez ci dessous la synthèse des questions relatives à Aquatics :

Le traits aquatique ne donne pas de malus sur les mondes dit idéaux (gaïa, anneau monde, oecuménopôle) mais le malus est bien présent sur les habitats.
Avec l’ascension Hydrocentré, il ne sera pas possible de terraformer les mondes désolés avec l’arme du colosse. Ou alors la planète a le modificateur “candidat à la terraformation”. Utilisée sur des cibles classiques, l’arme (Déluge) transforme la planète en monde océan et élimine au passage toutes populations non aquatiques.
Enfin il est possible d’utiliser l’ascension “Maîtrise de la nature” sur les mondes que vous avez déjà agrandis grâce aux mines de glaces. Bien sûr cette augmentation de l’espace sur la planète via la récupération de glace n’est pas infinie (en particulier pour des raisons d’équilibrage). Enfin pour vous aider, une indication sur la carte galactique apparaîtra pour vous prévenir de dépôts de glace dans un système.

Place maintenant aux notes de la mise à jour :

Spoiler:
Nouveautés pour Aquatics :

Un empire prescripté avec pour thème les nouvelles espèces,
Un nouveau phénotype avec 16 portraits autour du thème, un nouveau jeu de vaisseaux et des images pour les villes et fond d'écran diplomatique,
Une nouvelle voix de conseillé,
Un nouveau trait d'espèce, aquatique, 2 nouvelles origines, une ascension et un civisme.
(NdT : voir le carnet n°229 pour les détails)

Nouveautés pour Humanoïdes :

Un nouveau civisme Puristes Pompeux (carnet n°228).

Nouveautés pour la mise à jour 3.2 "Herbert" :

* Multiplayer hosts that own the DLCs now unlock portraits as well as ship and background sets from the Plantoids and Humanoids Species Packs for clients that do not own them.
* Added the ability to pick your main species' gender during game setup.
* Added over 200 new star names for random galaxy generation.
* Added 13 random events to terraforming to make the feature more engaging.
* Added 4 new asteroid-related anomalies to spice up old anomaly categories.
* Added 4 new Gas Giant anomalies.
* Added 4 new anomalies to existing, uninhabitable worlds anomaly categories.
* Added new options to several old anomaly events which share categories with the newly added ones above.
* Enabled the Ship Browser for all players.

Mécaniques :

* Reinforcement fleets will now attempt to find a safe but longer path if the shortest path to the target fleet is not considered safe. This will reduce how often reinforcement fleets are spawned at the shipyard at the cost of increasing the MIA time (due to taking a longer path) in these cases.
* Reinforcement fleets now consider systems that have both hostiles and allies in them to be safe for pathfinding purposes.
* Reinforcing fleets using jump drives no longer require a safe hyperlane path to the fleet they are reinforcing.
* Improved how shipyards are selected when constructing reinforcements to better utilize stations with multiple shipyards and mega shipyards.
* Reinforcing fleets that fail to find a safe path to the target fleet will now merge with other fleets orbiting the same shipyard, if both fleets intended to reinforce the same target fleet.
* Plantoids and Fungoids are no longer forced to have no gender, as you can now freely pick species' genders. Instead, every randomly generated species now has a 30% chance of being one of: genderless, female-only or male-only.
* Added an additional option to the Alien Box event chain for Gestalts.
* Added an Industrial colony designation to Ecumenopolis.
* Made it so colony events will not fire on newly terraformed worlds to avoid some Ludonarrative Dissonance.
* The default flag of new empires is now randomized, say goodbye to the red-black triangle flag!

Équilibrage :

* Functional Architecture and Constructobot: Reduced the free building slots granted from 2 to 1.
* Agrarian Idyll empires now get one planet building slot per four Agricultural districts built.
* Reduced the ship upkeep cost modifier for Clone army Admirals variants to 5/10/20% respectively.
* Ruins of Shallash arc site no longer has a chance of giving quite as much unity as defeating an endgame crisis.
* You can no longer use planet killer weapons on primitives inside your borders if you lack the appropriate primitive interference policies.
* Pops working the Livestock job now have 10% less political power.
* A lot of anomalies were rewarding 3 Society Research deposits, there is now more variety.
* Made Awakened Fallen Empires use Traditions.
* Several productivity-improving technologies are now no longer of dubious benefit, as their upkeep (and production) effects now only apply to jobs actually primarily producing resources.
* Nerve Stapled Hivemind pops can no longer perform complex drone jobs.
* Reduced the amount of jobs added by Leisure Arcology Districts to bring them into line with other Ecumenopolis districts.
* Ion cannons are no longer free to maintain, and have an upkeep cost of 8 energy.
* Necro-Hives:
* * Cut Necrophage pop assembly penalty to 50% from 75%
* * Made pop output modifiers (positive and negative) no longer apply to hive minds.
* * Made the -50% organic upkeep also apply to energy, for photosynthesis.
* * Devouring Swarm Necrophages now spawn with extra infrastructure to account for the lack of chambers of elevation.
* Life-Seeded now start with a 30 space planet

Performances et Stabilité :

* Fixed an OOS caused by using button effects in custom MOD UI, so now you can go back to building that Nicoll-Dyson Beam to "ensure galactic peace and prosperity".
* Improved the performance of pop factions updating their support values - resolved an issue where the game looped over every pop in the Empire for each faction, rather than calculating it once for the whole Empire and referring to that value for each faction.
* Improved the performance of planet_resource_compare trigger, and cut down on its use a bit as it's still quite expensive.
* Improved the performance of a variety of checks by making more extensive use of species happiness caching.
* Cached calculations of pop_has_random_ethics to reduce performance impact of repeatedly checking it, by 50%.
* Optimised Rising Unemployment event's triggers to be only 15% as costly.
* The game will no longer try (and fail) to run Grey Goo event True Masters on every planet, every day.
* Optimised checks for whether a pop can belong to a certain faction by pre-filtering pops by ethics in code (rather than running the script checks on all pops). For modders: this means that a faction will only allow pops which match its "guiding_ethic" in it, unless "use_guiding_ethic_as_pop_filter = no" is specified.
* Optimised several expensive pop faction demands that were checking all pops instead of all species, and similar.
* Improved the efficiency of checking whether a pop faction should exist.
* Optimised checks for jobs' "possible" trigger so that the four most common triggers are now pre-calculated per pop rather repeatedly for each job that a pop can take. (The format looks a bit different now, with possible_precalc, so modders will need to update a bit here - the error log will warn you in most cases, except that you also need to add a check when you use complex_specialist_job_check_trigger).

Interface Utilisateur :

* The Music Player controls bar now starts hidden and can be extended by clicking the music icon.
* The title of the Music Player is now localised.
* Pop strata icons no longer overlap in Living Standards' tooltips.
* Tab-key in Console now also lists commands containing entered text.
* Disabled "Delete" and "Update Template" buttons when editing a base species template.
* All languages now list the main menu hotkeys ("N" for New Game, etc).
* Added a description to how migration works to the Transit Hub star base.

IA :

* Improved AI algorithm for picking which building and district to build by fixing an issue where it would not handle buildings or districts which produced multiple resources very well
* Improved AI logic for building starbase modules and buildings. It will no longer spam crew quarters everywhere, and will instead be better at building useful things like resource-producing buildings and titan assembly yards.
* On starbases, AI can now build Ice Mining Stations, if it is hydrocentric
* On starbases, AI can now build Dragon Hatcheries if it got the tech
* On starbases, AI is building less crew quarters in general and in places where it doesn't make sense
* On starbases, AI is building a lot more anchorages
* On starbases, AI is also building a bit more solar arrays if it is a gestalt
* On starbases, AI is also building hydroponics now, since that has been buffed a lot and is way more useful to the economy
* On starbases, AI will now handle starbases after taking over from a player - but it will NOT build lots of defense modules everywhere and tank the economy that way
* Made AI empires more careful about running out of food.
* Rogue Servitors AI (and player default) is now to give their bio-trophies migration rights, rather than to not do so.
* The AI is now able to create Ecumenopolises.
* AI is now better able to budget for repairing the Shattered Ring World that Shattered Ring origin Empires start with.
* The AI is now better able to budget for terraforming, and will more readily terraform planets into classes which are ideal for them.
* Fixed AI sending small fleets to attack starbases without grouping up.
* Fixed AI trying to build starbase buildings and modules it wasn't allowed to be building in certain cases
* Improved AI weights for planet killer weapons, so they will tend to pick the one that benefits them the most. (This also applies to the player's auto-generated ship designs).
* The AI will now consider anti-crime campaigns a valid way of fighting crime. But it will also occasionally make deals with crime lords if it is the victim of a Criminal Syndicate.
* Fixed an issue where AI empires would leave fleets behind in others' space after peace was concluded.

Moddabilité :

* Starbase components can now accept economic output modifiers in station_modifier and system_modifier.
* Added on_queued and on_unqueued in decisions, and fixed a bug in abort_effect. (Also added an example sheet to show what all works: abort_effect and abort_trigger were probably hidden features).
* Added use of [loc] commands in decision descriptions.
* Fixed set_owner not working on Juggernauts.
* In component_templates, valid_for_country is now a trigger rather than a weights block, as that is how it acted. (So if you used it, you will need to update that).
* Added on_destroy_planet_with_<planet_killer_key>_queued/unqueued on_actions.
* Added species_gender trigger, which checks what gender settings a species allows.
* Fixed a mod compatibility issue where has_deposit would not predictably return false if referencing a non-existent deposit.
* Added a create_nebula effect.
* Changed terraforming costs to use the post-Megacorp economy system.
* Removed unused technology parameter terraform_cost_change (use regular cost modifiers instead).
* Removed 'energy' parameter from terraforming links (use 'resources' instead).
* Changed any_planet_army, count_planet_army, random_planet_army, and every_planet_army to no longer be restricted to armies owned by the planet owner. Use 'is_owned_by = planet.owner' as a limit to achieve the same result as previously.
* Fixed issues with inputting prev and from scopes in fire_on_action.
* set_name can now be used on first contact sites.
* Added custom tooltips database for galactic objects with triggers to be executed for every system.
* Added allowed_planet_classes to trait definitions for locking traits behind planet class selection in empire creation.
* Added "show" trigger to ship size empire_limit to control when the limit is shown to the player.
* Added planet_clear_blocker_speed_mult..
* Fixed set_starbase_building/module to use slots starting with 1 rather than 0. This now matches both remove_starbase_building/module effects, and vanilla usage, but modders who compensated for this mismatch will need to adjust for the fix. Also improved error logging for these effects.
* Fixed missing names in tooltips for modifiers granted in triggered modifier sections of starbase building/modules.
* Fixed starbases only refreshing slots on the next day after you use set_level, so set_level and directly followed by set_starbase_module would not work.
* Added ideal_planet_class to traits. It can be used for defining which planet class a habitability trait should apply to.
* The add_trait effect’s tooltip now says what the trait does.
* Fixed the "no" cases of several boolean triggers: is_bottleneck_system, is_idle, has_war_goal, has_valid_ai_personality, is_site_under_excavation, is_site_completed (they previously counted “no” as “yes”).
* Added defines for the thresholds controlling when to accept a longer path for reinforcements when the shortest path is not safe.
* Added REINFORCE_MIA_TIME_MULT and MIA_TIME_MULT for controlling reinforcement and MIA times.
* Replaced define variable SHIPYARD_REINFORCE_MAX_DISTANCE with SHIPYARD_REINFORCE_MAX_JUMPS.
* Replaced define variable SHIPYARD_DISTANCE_DIV_FACTOR with SHIPYARD_REINFORCE_DISTANCE_MULT.
* Removed define variable SHIPYARD_MAX_OVER_CAPACITY.
* Added finish_arc_stage console command for finishing the stage of the archaeological on the selected planet.
* The "possible" trigger of a tradition category's adopt tradition will now print in the tooltip for adopting that category if it fails.
* Added the possibility to get the number of civics for an empire scope with "civics_count" trigger.
* Added the possibility to remove a civic by index e.g. "force_remove_civic = 2".
* Added on_capital_changed on_action.
* Added on_action on_planet_class_changed.

* The notification shown when upgrading a defense platform now only appears when all queued upgrades are complete.
* Fixed the purchasing event of the Ministry of Culture displaying the wrong job for Machine empires.
* Changed the Atmospheric Hallucinogen modifier to more accurately follow the flavor text.

* Shattered Rings should no longer turn into spheres when the Gray Tempest attempts to turn it into a nanite world.
* Racket Industrial Enterprise will no longer say they will give you 4 pops and then only give you 3. They also realized that while trying to scam you they were giving you a great deal so they increased the cost of the pops.
* Catalytic and Master Crafter habitats colony designations should behave as expected.
* Citadel of Faith, Auto-Curating Vault, and Vault of Acquisition are no longer gated behind the wrong planetary capital building.

* Made it so subjects can't join federation if federation law states that subjects can not join.
* Made it so that fleets in combat while a star eater destroys a system ends combat and goes MIA.
* Fixed 'newly founded colony' immigration pull accidentally capping out at 15 months after colonisation rather than 15 years. Now correctly set to 15 years or a population of 10 pops, whichever happens first.

* Fixed the assimilation process overwriting/resetting species rights in certain circumstances.
* Fixed references to "pc_shattered_ring_habitable_adj" in certain first contact event chains.
* Fixed Policies sometimes showing that they could not be changed until a date that was in the past.
