Entry 285

Open questions after the triage: towns, fields and dungeons

world

This entry answers the question left open by The Chaos Gate keyword system, reproduced and checked against the game code, Dungeon and field generation, reproduced and checked against the game code, The area generator is the same on all four volumes, but two story areas moved into data, Dungeons, fields, battle and text checked on every volume, "Towns are assembled by code: the placement tables, carried into the port as data", "A town's other files: the crisis versions, and the canal water", The dungeon generator ported to Rust, with its tables as generated data, Dungeons in the viewer, and ExtObj copies are instances, The field generator ported to Rust, heights bit for bit, Into The World: Log in lands in Mac Anu, and Kite walks under pad control, Mac Anu's people: the five merchants, the walking PCs, the character layer and talking, Into the field: Kite leaves Mac Anu for field 14 and its dungeon, the set-up and the walk checked against the game, The first fights: event 3's goblins, the portals and free play in field 14, Kite and Orca against the game's enemies, The fight's sounds and the spells: ccSeOn3D and the sound tables, and attack spells cast through the effects, Event 11 in Mac Anu: BlackRose's stream, the Chaos Gate's talk, and her call into the party, Story starts to the ending: events 15-31, where each opens, and what they run into, Dun Loireag: ROOTTOWN02, its clouds, lens flare, water and map, and the town's game for town 1, The hacked arrival: the Chaos Gate's movie, Kite hacking out, and the party hidden until he has, Back in the town with the field's party: the registry carried, the members at their StartPos, The scripts' last host gaps: a companion's item_add, virus_core's level, room by RoomSelect, save_party, The event's NPCs outside the towns: Meg and the Administrator in the dungeons, The dungeons' breakables: EntryBreakObject, Dun Loireag's dogs: ccSetDog, ccDog and NorainuMenu, "A member's own orders and the field objects' menus: ChatMenu1-3, ItemObjMenu to TimeIdolMenu", "The Zeit statue: timeSym and the gameCnt clocks", "Dun Loireag's Grunties and the Grunty foods: ccPGuso, ccGimFood and menus 43, 45 and 46", The Spring of Myst and the boss rooms' warnings: ccGimEtc and menus 40-42, A field's gimmicks: SetFood, SetMagicCircle and SetSpecialObj, "The riding Grunty: ccPucciguso, the Grunty Flute and pgRideFlag", "Hideous Someone's Giant: area 16's EVENTAREA07 for the post-ending side event", "A lake's two dungeons: each kept by its number, lastRoom, and the way back up (GoField for field type 4)", "The carry's votes checked against content: a name whose table reads like Infection's stays", Spoken to while running: the greeting's stop reaches the member; the field's talk target and the town's faces.

This entry closes the open questions of 33 entries about the world: the area words and the generators, the Root Towns, the fields and the dungeons, their objects, gimmicks and people. The triage of 2026-09-28 (UNKNOWNS.md) split every entry's open paragraph into single questions and checked each one against the later log, the docs and the code. The answered ones are listed below with their evidence. What is still open is restated at the end, with the entry that asked it, the play questions first. Open questions of these entries that belong to another subsystem are restated in that subsystem's entry: 282, 283, 284, 286, 287, 288 and 291.

Still unknown
  • (play) [[191]]: come_back builds the lake room's doors open, where the game asks ccCheckActiveObject — climbing back into a lake dungeon. - (volumes) [[206]]: where Mutation's and Outbreak's idolItemList44 is; neither candidate reads like Infection's. - (volumes) [[260]]: Fort Ouph and Lia Fail are not compared with the game in eemu. - (volumes) [[275]]: Outbreak's and Quarantine's fellow deletes are not compared; no name was carried. - [[11]]: what each value of fieldType, weather, ground, object and circleOfs looks like in the game; the port runs the ported generator and draw for every value ([[33]], [[38]], [[130]]), but there is no catalogue (docs/engine/area-words.md Unknown). - [[11]], [[19]]: EVENTAREA_INFO.model beyond the sound bank and the story map file; .protect beyond protect[1] and the item pairs; .dungeonNum (docs/engine/area-words.md Unknown). - [[21]]: what area 126 is: a record with no address, added from Mutation ([[220]]). - [[21]]: why area 47 gets a different item offset from volume 3 (design; the mechanism is in [[21]]). - [[179]]: whether any Infection field is hacked outside the crisis (EVENTAREA_INFO.flag 3); not surveyed. - [[19]]: why dungeon types 8 and 9 pick a down-stairs room on their single floor (docs/engine/dungeon.md Unknown). - [[19]]: sd4a.cmp, named by DungeonName2 but not in DATA.BIN. - [[25]]: what DUNGEON.ishack means; [[161]] reads 3 as hacked (the lakes' fireflies) (docs/engine/dungeon.md Unknown). - [[114]]: area 67's type-34 row behind a door with no branch would crash the game; whether the story reaches it. - [[33]]: where the game would loop forever, the port gives up with NoSite; no case has reached it. - [[28]]: why the canal water is three copies of one animation. Water 0 draws the refraction and waters 1 and 2 scroll in U and V ([[97]], docs/engine/town02.md), but what the first copy's other Duplicate flag (8200 against 8192) changes is not known. (The triage cited docs/engine/root-towns.md here, whose undrawn waters are Carmina Gade's.) - [[28]]: what draws type 0 rows in the town classes other than ROOTTOWN01; not traced. - [[163]]: what row 19 with param[2] 0 was for; no setter leaves it 0. - [[163]]: GetNearDoorPosition with every mark beyond 12,000 returns stack words; the port keeps the row's place. - [[164]]: the game's result for a field with no dungeon entrance (in-points 0). - [[164]]: the node places of the field's objects use the dungeon posing, checked on rooms only. - [[164]]: where the foods stand in the game; sums put them 250-370 from the centre, not looked at in a picture. - [[154]]: the fourth clock (+0x70) has no reader found. - [[154]]: the Zeit statue, on the last floor of its dungeon, is not reached and opened in play. - [[191]]: what reads WORLD_MAN+0x58[n] (docs/engine/field-walk.md Unknown). - [[191]]: the walk between a lake's two dungeons against the game's run (docs/engine/dungeon.md Unknown). - [[111]]: RoomSelect's bgColor 0 and GS words are not modelled; the change's fade covers them. - [[134]]: whether Kite should walk around the fenced statue in a statue room's open doorway (area 18's dungeon). - [[72]], [[111]]: SimGenerateCode and GO move the global generator's seed and randcnt; the port leaves those draws aside (docs/engine/field-walk.md Unknown). - [[97]]: fieldrand's state on entering a town (the port starts at 13), and the scrolls' statics starting at 0 in each town (phase only). - [[112]], [[115]]: fieldrand's seed on arrival is not carried across scenes, from the dungeon or into the arena (the fireflies' bobbing; phase only). - [[157]]: a story dungeon's fieldrand after Generate (docs/engine/dungeon.md Unknown). - [[140]]: DungeonEntries.rng is a copy, so the dungeon's fieldrand does not advance with the breakables' draws; later draws can differ from the game's. - [[59]]: rand is not seeded from the game's shared state, so idle fidgets differ in time (a run's history). - [[65]]: whether a party member or the gate has a body on the character list. - [[65]], [[132]]: the second argument to ccSetRtownPC on the event path (ccEntryEventMng); the port uses -1 (docs/engine/field-game.md Unknown). - [[65]]: ccSys +0x358, the frame count that picks the PCs, is an input that depends on run time. - [[65]]: an event NPC placed after the set-up goes to the list's end; the order is not checked. - [[132]]: the event NPC classes step outside the entry control's NPC turn, so their effects start a frame late (docs/engine/field-game.md Unknown). - [[277]]: whether a walking PC can run off in a case the tests do not cover; only a member's run was caught. - [[108]]: the town branch of SetCharPosition is read, not run; its offsets match the field's checked ones. - [[110]]: the town frame gets menu_type -1 or 0, not which menu. - [[110]]: a second rebootSpcManager in one town visit makes no new AI for Kite's stand-in. - [[90]], [[103]], [[180]], [[250]]: inviteSpc in a field or dungeon: whether it is ever reached, and its copy of the table's equipment into the registry, not ported because no script makes one (docs/engine/field-game.md, field-walk.md Unknown). - [[106]]: how long the game holds the Chaos Gate loop (ccLoadResourceFL's time) (docs/engine/field-walk.md Unknown). - [[106]]: ghoCam's markers from the desktop's anm player, not compared (docs/engine/field-walk.md Unknown). - [[142]]: ccDog's constructor leaves the stuck count (+0x21c) unset; the port starts at 0. - [[142]]: the dogs' walks, not compared frame by frame. - [[162]]: the Grunties' camera writes land a frame's NPCs later than the game's (ordering). - [[162]]: runAway's one frame of checkHitResultAttlibute; the harness lacks the collision's last result. - [[166]]: the ride's task and its first cancel check run a frame later than the game's (ordering). - [[166]]: the port sleeps and wakes the whole party, where ccSPC::Wakeup wakes only those in it (the same in Infection's fields). - [[166]]: plw +0x10 and ccDamUprStr::CtrlAll in the ride menu's waits are not kept. - [[166]]: the Grunty's legs' places come from the port's last pose, not the game's last draw. - [[166]]: riding into a dungeon's way in (pgDIN) is not played through. - [[177]]: area 16's EVENTAREA07 against a game picture. - [[272]]: EVENTAREAB8 is held by unit tests, not compared with the game's Draw (docs/engine/evarea.md Unknown).
