In story:4 every block of event 4 fired in the dungeon's first room. Orca opened with his line for the dead end instead of his line for the dungeon's start, and the event cameras were placed for rooms Kite was not in (82, 86). The combat agent's third increment adds what the game does between entering a story dungeon and its events.

Each block in its room

WORLD_MAN::SetEventData() (main 0x001a3c40) runs from ccSetupGameCtrl, between ccStartThEvent and ccEnableThEvent(0).

• When. In a dungeon of a story area with an EditDungeon entry. It reads the area's first entry, whichever dungeon the party is in.
• Rooms. Each room row with an event flag becomes an event point (ccEvent::SetEventPoint, 0x001b3620).
• Gimmick rows. Type 2 becomes an event position with its facing (SetEventPos, 0x001b3590); type 3 with kinds 7-26 becomes a warp point.
• Slots. Each call fills the first of 16 slots whose number is negative, and does nothing when none is.

A block's set in_point n is then true only in the room of point n. In story area 14's D0001 the points are:

The doors

• Setting a room's doors. SetDoor (0x005c7c30) makes a door per door dummy. Each stands open if nothing of the entry control belongs to the room (ccCheckActiveObject), else shut.
• Each frame. MoveDoor (0x005cd3d0), from Draw, opens a held door a step a frame from the first frame the entry control has nothing switched on, with its sound.
• From the scripts.
  • open_door (case 158) is OpenDoor (0x005c8820): every door runs its whole length and stays open.
  • close_door (159) is CloseDoor2 (0x005c8800): each leaf sinks into the floor over the animation's length, then the doors are made again.
• Event entries. ccEntryEventMng calls CloseDoor (0x005c8f50) for each event entry, so a room an event fills starts shut.

The rest

• The 2D map. Get2DMapPtr / Get2DMapInfo / GetRoom2DPos give the party's path finding the current room's part of the floor map.
• Clearing bootParam. ccThSpcDelete (0x005a06d0) zeroes bootParam as an area ends. battle.md had said nothing clears it.
• Event task off during the world's own scene changes. The entrance, the doors and Gate Out turn it off (ChangeRequest calls ccDisableThEvent).
• area_host. It now answers stream, remove_trap, open_door and close_door.
• Entering. Walking from field 14 into its dungeon now works.

Checked

• Against the game (test_dungeon_rt, 0 mismatches):
  • EventDataAgainstGame runs SetEventData for 102 cases: 204 SetEventPoints, 254 SetEventPoses and 10 warp points. It also runs the real SetEventPoint/SetEventPos on 300 random slot states.
  • test_doors covers 75 rooms with doors: 12,846 MoveDoor steps, 44 OpenDoor, 35 CloseDoor, 72 CloseDoor2 and 332 door sounds. The hit lists are identical.
  • test_dungeons compares GetRoom2DPos for all 672 rooms.
• Runtime test. event_4_plays_in_the_dungeon: every block in its room, the trap room's goblin fought down, the doors opening, and out to mode 3. It tests the port against itself.
• The disk failure. It stopped the first verification (86).
• Re-run after the failure. It ran in the rebased worktree, one job at a time with the build guard. Passing:
  • fmt, clippy, the workspace's tests and the docs check;
  • test_dungeon_rt, test_dungeon_rs, test_field_rs and test_world_rs;
  • the battle navi, fellow and event suites;
  • test_gamectrl_rs and test_evarea_rs.
