"Stairwell"; Lua exposes `stairRectName` on the `CellGrid`
|
||||
component. A stairwell room on the top floor has no floor above -
|
||||
the generator warns once and ignores those flags.
|
||||
- Automatic stairwells (phase 7.3a): `TownGenSystem::
|
||||
fillBuildingCells` calls `autoPlaceStairwell()` for plans with more
|
||||
than one floor. An explicit plan stair cell wins; otherwise a
|
||||
deterministic straight run is carved along the longer usable axis
|

(4 cells first, 3 as a fallback) on the first row/column that is
|
||||
free of door cells and has a boarding cell on the ground floor and
|
||||
a step-off cell on the top floor. Interior walls + internal
|
||||
windows on the run cells are opened (the run may cross room
|
||||
boundaries), as are the facing walls at the boarding and step-off
|
||||
cells. When no run fits, one `TownGen: warning - no stairwell fits
|
||||
building ...` line is logged and the building stays as before.
|
||||
This covers the built-in parametric layouts, `town_layouts.txt`
|
||||
layouts and inline sources without editing layout text; exterior-
|
||||
only shells are unchanged (stairs are interior geometry). The DSL
|
||||
help window documents `:type stairwell` + the automatic stairwell,
|
||||
and `LayoutLibrary::examples()` ships "Two storeys, automatic
|
||||
stairwell" and an explicit-stairwell-room recipe.

- Climbability envelope: the Jolt character only mounts a 0.174 m
|
||||
riser when the approach is fast enough and the tread is not too
|
||||
short. Measured: 1.4 m/s (NPC walk) and 1.5 m/s climb 0.30 m and
|
||||
0.248 m treads; 1.2 m/s does not. Straight runs therefore need at
|
||||
least 3 cells at 2 m cells (tread >= ~0.25) - 4-cell runs
|
||||
(tread 0.30) are the verified default - and a one-cell 2 m dogleg
|
||||
(tread ~0.09) is never climbable (the dogleg layout is for larger
|
||||
cells or hand-authored grids). `FurniturePlacement::canPlace`
|
||||
rejects stair cells and the cells directly above them ("blocks a
|
||||
stairwell" / "above a stairwell opening").
|
||||
- Exterior stairs (phase 7.4): `CellFlags::ExteriorStair` (bit 27) on
|
||||
an upper-floor boundary cell with an exterior door builds a motel-
|
||||
style outside stair: a 1.5 m walkway landing at the upper floor
|
||||
flush with the door, a 0.9 m outer rail (wall buffer + collider),
|
||||
and a straight solid flight descending along the facade to the grid
|
||||
base level (0.18 cap, tread 0.30, 1.4 m deep against the wall),
|
||||
using the stair mesh + collider. The facade side comes from the
|
||||
cell's door/window/wall bits (exactly one door side required); the
|
||||
flight direction is the along-facade side with room for the run
|
||||
(+ preferred) and may extend past the building corner over the
|
||||
ground. DSL: `(floor n (door side offset :gallery))` (upper floors
|
||||
only); the DSL help documents it; the editor flag list shows
|
||||
"Exterior Stair". Limits: no rail along the flight; the flight
|
||||
bottoms out at the grid base (the terrain foundation must meet it);
|
||||
the gallery door is a normal door (closed leaf blocks the capsule,
|
||||
the navmesh treats doors as passable per F7).
|
||||
- Grand / lobby stairs (phase 7.5): the layout follows a stairwell
|
||||
block's aspect - compact blocks build the two-flight dogleg,
|
||||
elongated blocks (aspect >= 1.5, run >= 3 cells) build ONE wide
|
||||
straight flight spanning the block's short side (width =
|
||||
shortCells * cellSize - 0.30); single-row runs keep the 1.8 m
|
||||
comfort cap, so existing layouts are unchanged. Wide flights reuse
|
||||
the same step contract. Curved/branching flights and railings
|
||||
inside stairwell rooms are explicitly out of scope (the shaft walls

enclose the flights; an open grand stair ending mid-room would need

a railing system).

||||
interior geometry): generated town fronts stay bit-identical.
|
||||
- Furniture placement now refuses stair cells and the cells directly
|
||||
above them (`FurniturePlacement::canPlace`: "blocks a stairwell" /
|
||||
"above a stairwell opening"), so room furniture cannot block a
|
||||
stair or float over the opening.

|

|

Open design question carried over from the original phase notes:
|
||||
typing a room `stairwell` is the easiest DSL/component authoring
|
||||
path, but lobbies of hotels, theatres and administrative buildings
|
||||
want a **large stair inside an ordinary room** — wide flights,
|
||||
possibly curved or branching, not a utilitarian shaft. Research
|
||||
first: how a wide multi-cell flight is authored (room option vs.
|
||||
dedicated cells), whether the 7.1 straight/dogleg layouts suffice
|
||||
when scaled up, and what railing/balustrade geometry is needed.
|
||||
Only then implement.
|
||||
#### Phase 7.4 — Exterior stairs (motel-style) — DONE
|
||||
|
||||
As built (2026-10-30):
|
||||
|
||||
- `CellFlags::ExteriorStair` (bit 27, mirrored in `PlanFlags` with a
|
||||
static_assert) on an UPPER-floor boundary cell carrying an exterior
|
||||
door on one side. The generator builds, outside that facade:
|
||||
- a walkway landing in front of the door (1.5 m deep, flush with the
|
||||
upper floor surface) with a 0.9 m outer rail band (wall buffer +
|
||||
collider, so nobody walks off and Recast sees the edge), and
|
||||
- a straight flight descending along the facade from the landing to
|
||||
the grid base level: 0.18 rise cap (0.175 at 4 m floors, 24
|
||||
steps), tread 0.30 shrunk only when the facade is short (warn
|
||||
below 0.12), solid boxes, depth 1.4 against the wall.
|
||||
The flight runs in the direction (along the facade) that has room
|
||||
for the run, +axis preferred, and extends past the building corner
|
||||
over the ground when needed. Steps go into the stair mesh with its
|
||||
collider; the rail goes into the internal wall buffer. Warnings
|
||||
(once per cell) for: ambiguous facade doors, no facade opening at
|
||||
all, no room for the flight, and the flag on the ground floor.
|
||||
- Authoring: the DSL door verb accepts `:gallery` on upper floors -
|
||||
`(floor 1 (door front -4 :gallery))` marks that door cell as an
|
||||
exterior stair; the DSL help window documents it and the room verb's
|
||||
stairwell note. The Cell Grid editor's per-cell flag list shows
|
||||
"Exterior Stair" automatically. Serialization rides the raw cell
|
||||
flags (no schema change); Lua unaffected (no new component field).
|
||||
- Limits (documented, not blockers): no rail along the flight itself
|
||||
(only the landing rail); the flight bottoms out at the grid base
|
||||
level, so the terrain/foundation must meet the building base (the
|
||||
town foundations already do); the gallery door is a normal door -
|
||||
a closed leaf blocks the capsule until opened, while the navmesh
|
||||
treats doors as passable (F7).
|
||||
|
||||
Verified:
|
||||
- `TERRAIN_TEST_FILTER=cellGridStairs` builds an exterior fixture
|
||||
(5 x 2 x 3 grid at 2 m cells, upper door + exterior flag): the stair
|
||||
mesh reaches the upper floor and has geometry outside the facade
|
||||
(z > 5), and a Recast path runs from the ground to the upper floor
|
||||
through the gallery door.
|
||||
- `demoTaxi --test-stairs` gained an exterior-walk phase: a capsule
|
||||
climbs the outside flight from the ground to the gallery at NPC
|
||||
walk speed (PASS at Y > 3.9). `road_geometry_overlap_test` asserts
|
||||
the `:gallery` DSL flag placement. CTest 9/9 and the demo
|
||||
batteries stay green.
|
||||
|
||||
#### Phase 7.5 — Grand / lobby stairs — DONE
|
||||
|
||||
Research conclusions (2026-10-30):
|
||||
|
||||
- **Authoring unit: the existing `:type stairwell` room**, no new
|
||||
verb. The room's aspect decides the layout: compact blocks keep the
|
||||
two-flight dogleg; **elongated blocks (aspect >= 1.5, run of >= 3
|
||||
cells) now build ONE wide straight flight** spanning the block's
|
||||
short side - the grand lobby stair. Wide flights are a generator
|
||||
change on the cell flags, so hand-authored multi-row `StairWell`
|
||||
blocks and DSL stairwell rooms get them alike.
|
||||
- **Curved/branching flights: out of scope** (documented). A curved
|
||||
stair would need a path-based mesh generator and is not justified by
|
||||
the current building stock; branching is expressible as two
|
||||
stairwell rooms.
|
||||
- **Railings**: not generated inside stairwell rooms - the shaft walls
|
||||
enclose the flights, and a wide flight spans the room up to the
|
||||
0.15 m ring margin per side. An open grand stair ending mid-room
|
||||
would need a railing system; deferred (the shipped layouts do not
|
||||
need it).
|
||||
- Wide flights reuse the 7.1 step contract: 0.18 rise cap, 0.30 tread
|
||||
(shrunk on short runs with a warning), solid boxes, stair mesh +
|
||||
collider, `stairRectName`/floor rect material.
|
||||
|
||||
As built: the block branch of `CellGridSystem::buildStairs` computes
|
||||
the block aspect; aspect >= 1.5 with a run of >= 3 cells emits one
|
||||
straight flight across the full short side (width = shortCells *
|
||||
cellSize - 0.30); otherwise the dogleg is kept. Single-row runs keep
|
||||
the 1.8 m comfort cap, so existing layouts are unchanged.
|
||||
|
||||
Verified: the `cellGridStairs` terrain step adds a 3 x 2-cell stairwell
|
||||
block in a 6 x 2 x 6 grid and asserts the stair mesh's first tread
|
||||
spans one continuous 3.7 m wide flight (z extent at the tread-top
|
||||
level) and the level above is opened over the whole block;
|
||||
`road_geometry_overlap_test` and the demo batteries stay green. The

DSL help window documents the wide-stairwell room and ships a "Grand
