It now reusesthe largest existing room in almost every possible case, avoiding the need to flood-fill a new onefrom scratch. Before this all started, map changes cost 5ms on my machine because theyreflooded every room on the map at the square level. Now they cost 0.05ms, a 100x speedup.Even better is that the new algorithm is insensitive to map size.

These were causing slowdowns in large colonies with lots ofitems by allocating a lot of heap memory for each item scanned, and for each square in which onemight store each item scanned.

April 13

● Various bugfixes.● Refactored item dropping code to better report results with items that could not be dropped orcould only be partially dropped (into existing stacks).

April 12

33 de 45 15-04-2015 17:46


● Bug fixing and many small tunings.

March 27

● Testing, grinding down bugs, tuning many small aspects of many systems.● Spent a while de-spaghettifying map initialize code, as well as moving the world data out of themap itself.● Colonists now start out with the work types they’re best at enabled, instead of everyone havingthe same settings.● New alerts make tiny bell noises.● Different teams have different color names by randomly shading within the red range (hostile) orblue range (neutral). So you can tell apart two different hostile groups.

March 26

● You can now suspend bills without deleting or modifying them for easy later reactivation.● AI will now immediately store items after creating them at a bench (if there are multiple items,the first one will be automatically insta-stored). This is part of the crafting job and is independent ofhauling.● Testing and grinding down bugs produced over the past few weeks.● Various minor usability improvements.


● Added a simple planning designation that does nothing so people can plan base layouts early.● Friendly factions will not help you fight their own friends.● Built up and redesigned AI code so factions can fight each other properly.● Staging enemies no longer assault you on sight. They will hold their staging position anddefend. Hopefully pre-emptive attacks become more meaningful this way.● Enemies now stage attacks for randomized amounts of time.● Ally forces now hang around a reasonable point near your base if there are no enemies. Aftersome time, they leave together as a group (they become travelers).● If harmed, traveling groups stop and defend as a group. They resume traveling if they are notharmed for some time.● Roughed in visitor event: groups from non-hostile factions visit the colony, chill for a while, andleave.

March 24

● Stonecutter’s table now requires research.● Faction relations now measured on a -100 to 100 scale instead of 0-100.● Roughed in a way to call allies for combat aid. If they like you enough, they’ll send a group offriendly fighters to help you. Useful in a pinch against tough raids.● Travelers arrive in groups sometimes.● Can no longer place a no roof region where there is a thick roof.


● Redesigned AI King into a proper state machine so it can handle more complex multi-factioncombats and more intricate goals.● Refactored traveler behavior as a king of squad directive, so you can have traveling groups whostay together.● Created “get mods” Web link in mods page.● The tutor now properly teaches about the bills tab.● Humanoids no longer eat raw food unless they are near-starving at least.


34 de 45 15-04-2015 17:46

● Added a button to select through things in the same square (you could always do this by slowlyclicking)● Colonists don’t eat raw food unless urgently hungry or starving.

March 14

● Added new styles of raid: immediate assault (no staging time) and center-drop (they drop rightinto your colony).● Reworked early-game alerts into a todo list style. “Need growing zone”. “Build a room”. And soon.● Now, if someone tries to get food from a paste dispenser fails, they first try to fill it, even withoutbeing assigned as a hauler or cook.● Corpse hauling is now globally prioritized above other hauling.● Right-click prioritize menu now gives sensible reasons why actions cannot be prioritized (e.g.haul -> “no place configured to store this”)● Bill dialog now warns you if you add a bill that no colonist has the skill to do.● Drafted pawns now automatically beat adjacent fires.

March 13

● Added help message about trading from orbital beacon in first-opened trade screen.● Added hotkeys for architect mode.● Merged architect and direct mode code for displaying commands. Direct mode now displayscommands for selected things along the bottom of the screen, the same way Architect mode does.● Added shortcut keys for next/previous colonist (default comma and period keys).● Game can now natively load dictionaries of data with def references as keys or values.


● Launch pad replaced with orbital trade beacon. Trade system clarification commences.● Mental break probability is much lower.● Added a cancel button on the in-progress buildings.● Colonists will now sleep on the ground if exhausted.● Bills no longer vanish on hitting zero count (you can reactivate them without reconfiguring them).● Bill config interface displays ingredient search radius ring.● Alerts now have a moving arrow to draw attention to critical alerts. They are draw on top of theletter stack and so are more visible.● It is now impossible to place a hopper in an invalid position.● Modders can now create custom Def subclasses.● Modders can now make custom code to define building placement restricters.● Colonists now undraft themselves if they’ve been doing nothing for at least a quarter of a dayand there are no enemies on the map.

March 11

● Colonists don’t get sad about being in darkness until they haven’t seen a light for 3-4 hours.● Corpses can now rot.● Pawns now spawn with randomized goodies. Yay, something to steal!● Faction relations change over time.● For modders: Beauty and TransmitsPower are now overridable properties of Things andBuildings.

March 10

35 de 45 15-04-2015 17:46

● You can now call factions on the radio and talk to them. You can offer them silver to improverelations.

March 9

● Mods list is now scrollable.● Can now individually hide zones.● Tribals now have special names (no more tribal Bob Smiths).● All pawn kinds can now carry stuff in their inventory, like silver, and will spawn with some.Hooray, a reason to attack people!● Created soft faction relations so factions can get progressively more and less pissed at you.

March 8

● Restricted hairdos by faction. No more pirates or tribals in pigtails.● Completed 28th revolution around the sun.

March 7

● Tribal raiders now spawn and attack. Created short bow, great bow, and handful-of-stonesweapons.● Solidified faction relations. They are now reported on the faction overview.● Pawns of warring factions now fight.● Let pawns spawn with minigun and L-15 LMG.● Refactored gun spawning system to work by tech level, spawn tags, and pawn kind money.● Created system to track the instigator of damage. Factions turn on you if you damage or kill theirmembers.● Pawns now spawn with backstories from appropriate spawn category for their faction.● Created some basic backstory content for tribals.● Started trying to fix save/load.

March 6

● Cleaned up pawn graphics and fixed it so they can be loaded from mods.● Made people spawn per-faction. Started adding tribal raiders.

February 28


36 de 45 15-04-2015 17:46

● Fixed external code loading.● Created the Fertilizer Pump external code test mod. Adds the fertilizer pump building whichuses electricity and slowly creates a growable soil field around itself.● Finished automated hunting. Colonists will hunt with guns or melee attacks.● Pawns now try to eat nice meals when they have the choice over nutrient meals.● Various bugfixes.

February 27

● Disallowed building very close to the map edge. This discourages weird building patterns thatexploit edges and corners and stress game systems.● Added basic music system. Added Al’s guitar sting for game start.● Resource lister now counts meals.● Added target amount for bills; colonists won’t do the bill if you have more than the target amountin storage.● Started automatic hunting. So far, colonists can go kick animals to death. Doesn’t work so wellfor boomrats.● Moved JobDefs into XML.● Job reports like “Hauling Metal.” or “Eating meal.” are now in JobDef, not code.

February 26

● Finished refactoring map generation into encapsulated, parameterized steps.● Added simple ruins generation.● Thick rock roofs now drop ‘collapsed rocks’ instead of solid rocks.

February 25

364 - February 24

● Bugfixes.

Februray 23

● Bugfixes.● Reworked debug lister menu to handle large numbers of options. Also added a type-in filter.

February 22Internal builds 361b/362

● Bugfixes.

February 21Internal builds 360a/b/c, 361a

● Finished up stone economy with stone walls.● Bugfixes.● Added blasting charges back in as a mod.● Started working on getting code loading with mods.

February 20Internal build 359

● Tons more bugfixes.


37 de 45 15-04-2015 17:46

● Work type definitions and work giver definitions are now in XML, so you can mod in new worktypes to correspond to new economy chains.● Added gather spots so you can make idle colonists gather around certain tables.● Added stone economy: stonecutter’s table, crafting worktype, stone cutting workgiver, stoneblocks thing, stone tiles floor, low stone wall, high stone wall.

February 19Internal build 358

● Tons of bugfixes.

February 18

● Extensive refactoring and bugfixing.

February 17

● Bugfixing and prepping for internal test cycle.● Added max ingredient search radius for bills.● Added qualitative descriptions to skill levels.● Skills now decay over time when at very high levels.● Created the passion system, which affects learning rate according to characters’ naturalinclination towards different subjects. As in real life, anyone can learn anything that they’re willingto do, but you learn a lot faster if you’re naturally interested in the subject.● Game save/load of lists, dictionaries, and hashsets now runs the same code whether savingsimple values, deep-saveable objects, in-map cross-references, or references to game datadefinitions.● Mods can now override core game data as well as add to it.● Storytellers are now defined in XML.● Made turret look and sound weak to match its functionality.

February 14

● Migrated all remaining Thing data into XML.● Rewrote how thing component data is handled (it’s no longer defined per enum on a centralizedlist) and migrated it all into XML.● Rewrote XML inheritance to inherit data about subelements and permit inheritance chaining(e.g. pawn->animal->squirrel).● Set up apparels to spawn according to who they are, data-driven.● Some late-night optimization, especially to the reachability checker, which, although not anexpensive algorithm, can be called thousands of times in a frame, and so needs to be fast as hell.

February 13

● Finished decent refactoring of effects system so it can be data-driven. Different meals/recipescan make different effects while being eaten/worked on.● Finished refactoring out the Interactive interface; all AI actions are now specified in AI code, notin the things they interact with.● Factored out a lot of EntityDefinitions. These are now used as mini-categories, not individualentity identifiers, so modders can add more entities easily.● Migrated pawn kind definitions (sniper, drifter, refugee, etc) into XML.● Migrated research project definitions into XML.

February 12

● Refactoring day.● Converted a bunch of old AI code into the new consistent toil format.● Converted all building definitions from hardcoded into XML.● Started modularizing EffectMakers and making them data-driven.

February 11


38 de 45 15-04-2015 17:46

● Recipe ingredients are now configurable and work using categories. You can tell your colonistswhat to butcher, and whether or not it should include people.● Balance: Colonists self-extinguish 2.5x more often.● Created cook stove and three meal types to cook. Advanced meal types require multipleingredients but have better psychological and nutritive effects.● Advanced meal types require advanced cooking skills.● Added varied food types from plants: potatoes, agave, and berries.● Added release-mode console GUI so modders can properly debug their content without goinginsane.

February 10

● Refactoring day.● Cleaned up and pumped up map save/load to be able to handle all sorts of funky cross-references. This was originally so I could save a colonist’s job with a true reference to the specificwork order they were in the process of carrying out.● Blasting charges cut (until they can be balanced properly).● Skill needs are now data-driven so you can define specific relationships between skills anddifferent recipes’ efficiency and work time.

February 7

● Started creating the “bill” interface so you can tell your colonists what to create at a recipestation. e.g. What meals to cook, what to butcher, etc.● Reactions are now called recipes.● Created a data-driven default settings system for storage buildings. Hoppers default to notaccepting human meat.

February 6

● Finished basic new AI failure condition framework.● Thoughts are now moddable definitions.● Cannibalism causes bad thoughts, differently depending on whether it’s eaten raw or cookedinto a meal. Colonists avoid eating it. Different meats look different.● Integrated first-pass weather and ambient sounds.

February 5

● AI: The old code for having AIs watch for job failure conditions is creaking under the strain. I’vecut it and started a new, more modularized failure condition watcher infrastructure. Now, when theJobDriver defines the high-level behaviors, the action and failure conditions won’t have to becoupled together. You’ll be able to configure and stack together failure conditions appropriate tothe job being done. This allows reuse of behavior code in different contexts (e.g. Hauling aresource to a stockpile, hauling a resource to a building site, hauling a resource to a table forreaction site have different fail conditions but can use the same hauling core code).● Started integrating Al’s ambient sounds.

February 4

● AI: Started the reaction/butchery/cooking system. Working on a generalized reactionsframework that characters will follow to transmute one set of items into another.● Letters now have varying urgencies. More urgent gets a hotter color. The most urgent ones alsobounce occasionally to get your attention.● Readjusted probabilities of solid and shuffled pawn bios appearing.● Combined pawn RaceDefinitions into general ThingDefinitions. All pawn definitions nowgenerate meat definitions.

February 3

● Guns and equipment, plants, and apparel are all now loaded from XML. Added rose decorative


39 de 45 15-04-2015 17:46

plant.

February 2

● Mods can now load content cross-references and images. Content handling is much cleaneroverall. In progress. Created Royal Bed test mod.

February 1

● Added mod browser. Restructured mod data to be configurable. You can now install mods andrun them in parallel. Created mod metadata screen (author, description, etc). http://puu.sh/6GuGD.jpg● Stockpiling AI: when on hauling runs, colonists now pick up extra resources from nearby pileseven if they can’t carry all of them.● Cooks taking food to hoppers now more perf-efficient and cooks will no longer fill hoppers thatare already nearly full.

January 31

● Trader kinds (farm vessel, slave trader) etc are now in XML and moddable.● For modding, I cleaned up the load sequence so it loads every definition in the game and allmods before resolving all references between them.● For modding, decoupled many references that found ThingDefinitions via their entitytypes, sowe can have lots of definitions that share entitytypes. Now they use the ThingDefinitions directly.● Created a no-roof region similar to the home region. The game won’t generate roofs in theseregions. In addition, player-constructed roofs are removed when no-roof regions are added.● Some small optimizations.

January 30

● Restructured how map section meshes are rebuilt to eliminate the in-between step thatallocated large amounts of data. Now things print directly onto the mesh’s working data, which is amajor optimization. Code is cleaner now too.

January 29

● Ridiculously huge performance improvements across the board due to simple rewriting of oldperf-blind code. For example, we no longer draw the whole map every frame(!) - and tons ofothers.

January 28

● Plant growing zones added, along with AI to find and interact with them. Redesigned work AI tohandle work on locations as well as things.● Added an options menu button to open your saves folder (nobody can find the damn thing).● Added an options menu button to reset the adaptive tutor.● Mac version now places Mods folder inside the app package to make the install cleaner.● Cleanup and optimization: TargetPacks and DamageInfo are now structs for better GCperformance. Made system to save TargetPacks when they refer to Things. Various other.

January 27

● Started some heavy refactoring of how different items fill different slots in a square.

January 26Internal build 334a/b, Alpha 1 Release Candidate 5 and public Alpha 1

● Bugfixes.● Added adaptive tutor messages for opening comms, setting storage priorities, and growing food.

January 25 -


40 de 45 15-04-2015 17:46

Internal builds 333a/b/c/d, Alpha 1 Release Candidates 1/2/3/4

● Various pre-release fixes.

January 24Internal build 332

● Created a consistent PathMode system to explicitly handle the difference between pathing to asquare and pathing to adjacent to a square or thing, in all methods and interfaces that handlefinding paths or checking reachability. Ambiguity between these was causing subtle bugs.● Performance optimizations and a worryingly large number of bugfixes.● Integrated Ricardo’s new menu background screen. Not animated yet, but you get the idea.● You now start with three guns, to alleviate problems with early-battle balance. The battles aresupposed to get harder as you go along, not easier.


● Bugfixes.


● Adaptive tutor now saves its estimates of the player’s knowledge as a separate file that willpersist between games. Delete Knowledge.xml (in savegames’ parent folder) to reset it.● Retuned adaptive tutor and reworked the internal numbers to all be percentages.● Major optimizations on the algorithm for regenerating rooms. Will help during mining.● Fixed some deep bugs in hard-case stockpiling (e.g. dropping food in a sealed room packedwith food).● Deconstructing is now done by designating a target, which the colonists go deconstruct.


● Worker AI rejiggered to allow prioritization of different classes of targets within one work type.The upshot is that they’ll try to finish existing unfinished buildings before carrying resources toblueprints.● Added preferred names list, so you can encourage the game to spawn your Name in Game orBackstory in Game character.● Rho did nicer thicker outlines for characters.● Various bugs fixed.

328 - January 20

● Stockpiling AI: Created cooking stub work type. Currently it only loads food into dispenserhoppers, so you can set this activity at a different priority than hauling.● Refined and tuned the adaptive tutor, added about six new concepts to teach.● Did a ton of low-hanging-fruit optimizations, greatly increasing the performance of the game andreducing memory allocations about 50%.● Small usability changes and bug fixes.

327 - January 19

● A pile of bugfixes, especially for stockpiling AI.● Continuing to tune the adaptive tutor and put in more lessons and cues.

325 - January 17

● Created adaptive tutor system. It watches everything you do and tries to determine yourknowledge of various concepts. If it detects a concept is needed but knowledge hasn’t beendemonstrated, it shows a helpful note. Effectively it tries to replicate a good teacher sitting behind


41 de 45 15-04-2015 17:46

you, saying only the things that are really needed.● Terrain, building, and terrain scatterable definitions are now all moddable. Concept definitions(used by the adaptive tutor) as well.● Stockpiling AI bug fixes.● Various bug fixes.● Imported the latest player creative content.

324 - January 16● Stockpiling AI: Pawns will now draw from several resource piles if it helps them build moreefficiently. So they can pick up from multiple resource piles, carry the resources in one trip, andthen deposit them in multiple building sites. Very efficient and fun to watch!● Included Rho’s new RimWorld logo and Ricardo’s happy/sad Randy portrait.● Various bug fixes.● Colonist will now eat from dispensers in prisoners’ rooms as well as store meals in prisoners’rooms if there is no prisoner present.● You can now rename stockpiles.● Some fairly easy but extremely impactful optimizations: eliminated 30k/frame of memory allocsfrom switching to the same font over and over. Game no longer tries to make tooltips from everyrock square in the map (only pawns make tooltips now). Some others.

323 - January 15● Stockpiling AI can now collect resources for multiple building sites when taking resources tobuilding sites. So if there is a long wall, they can collect a pile of metal and lay down a dozen wallsections at once instead of going back and forth for each one. They still only collect from oneresource pile.● Various bugfixes.

322 - January 14● A pile of bugfixes for stockpiling AI.● Updated credits.

321 - January 13● AI can now add to existing stacks in storage, as well as handle various contingencies with lackof space, and so on.● Unified thing dropping placement code.● Kassandra is now Cleopatra.

320 - January 12

● Integrated storyteller portraits in entry menus.● Various further bugfixes, some stockpile related, some old bugs.

318 - January 10

● Fixed another batch of stockpiling bugs, largely around configuration of special storagebuildings.● Had to scrap and try a new approach to having fixed default categories on the storage buildings.

317b - January 9

● Spent all day fixing bugs found by testers in the stockpiling AI system (and in other systems).Great thanks to Semmy for finding a huge number of bugs in this one.● AIs now haul construction-blocking items to the nearest open square instead of hauling them allthe way to storage.

317 - January 8

● Many, many bug fixes for stockpiling-related stuff.● Redid storage allowance system into a nice hierarchy, so you can allow/disallow storage ofindividual kinds of items in a stockpile, or do it by categories. All with a nice collapsible-categoryinterface.


42 de 45 15-04-2015 17:46

● Added jacket from Rho.

314 - January 6Back after a lull over Christmas.

● First attempt at basic stockpiling system. Many bugs are still in.● Lots of other little changes, most related to stockpiling. I’ve had to redo trading, money, howdispensers use food, how things are sold and resources reclaimed, and how things are built.● Lots of new art from Rho.

294 - December 17First testing version in a while after a lot of structural rework and post-crunch cleanup.

● Created audio authoring system, supporting one-shots and sustained sounds, various filters,pitch, volume settings, mappings from in-game parameters.● Created live-modding system, which allows modification of game content while the game isrunning. This includes the package editor and the definition editor.● Starting moving game content out of hardcoding and into external, modifiable xml and contentfiles. This is the beginnings of the mod system.● Created apparel system and introduced the first batch of apparel from Rho’s art.● Created a system to randomize, remember, and manage colors for apparel and characters’ skin.● Various other changes.
