The eight Act I outdoor levels (Blood Moor 2, Cold Plains 3, Stony Field
4, Dark Wood 5, Black Marsh 6, Tamoe Highland 7, Burial Grounds 17, Moo
Moo Farm 39) are now generated by the function-by-function port of
D2MOO's D2Common DRLG in src/game/drlg, bit-exact against a native D2MOO
oracle. The legacy Act I generator (src/game/wilderness/*, the Blood Moor
branch and the Act I paths of wilderness.ts) is deleted; there is no
fallback. Acts 2-5 are unchanged.
Port (completes the kernel committed earlier):
- Tile-map stage: DRLGROOMTILE_AddRoomMapTiles with its tile-data,
linked-tile and warp helpers, DRLGPRESET_AddPresetRoomMapTiles,
DRLGOUTROOM_InitializeDrlgOutdoorRoom (drlg-outroom.ts), the
DrlgDrlgLogic.cpp parts they reach (drlg-logic.ts), D2CMP shim updates.
- drlg-dump.ts: runAct1() driver API; schema 3 dumps with per-room tile
lists. The port is now type-checked (tsconfig no longer excludes it).
Integration:
- drlg-map.ts (replaces drlg/adapter.ts): turns a generated level into
the bake's DS1-shaped canvas with exact (style, sequence, type) per
tile and per-cell DT1 masks, objects, seams from the DRLG level links,
warps from their UNIT_TILE preset units; blank cells stay blocked.
- pack-act-assets: one D2 game seed per (act, variant), a DRLG bake job
and index.json actLayouts; scripts/lib/drlg-mpq-source.ts feeds the
port from the MPQs with the oracle's file list.
- act-variants.ts: WorldVariants picks one generated copy per act (and
the Rogue Encampment DS1 that copy fixed); act-scene.ts and
verify-world-walk both use it. act-scene no longer paints grass into
the blank cells of DRLG scenes.
- world-graph: remove the invented Stony Field <-> Dark Wood seam
(gAct1WildernessDrlgLink / gAct1MonasteryDrlgLink keep them apart;
they meet only through the Underground Passage); world-placement
anchors the second group at the Monastery Gate (3000, 1000).
- level-links: findBorderOpening takes an optional edge range.
- d2map: dt1MaskAllows extracted, behaviour unchanged.
Tools and tests:
- tools/d2moo-oracle: tile-map stage and schema 3; the 4 fixtures are
regenerated (scripts/drlg-fixtures.ts).
- scripts/render-drlg-compare.ts (both dumps through the same adapter
and renderer, fails unless the XOR is empty) and
scripts/audit-levels-browser.ts (headless audit of every baked map).
- tests/drlg-act1-oracle.test.ts (all stages, all 4 fixtures) and
tests/drlg-act1-invariants.test.ts; tests and stress scripts of the
deleted generator are retired or now run on Acts 2-5 only.
- verify-world-walk: start in the town the runtime opens and floor the
spawn sub-tile like the movement collision does.
Verification:
- drlg-diff --levels 2-7,17,39 --seeds 32: 32/32 identical at every
stage; --trace-check 64/64, --isolated 32/32, difficulty 1 and 2 16/16.
- render-drlg-compare, 3 bake copies x 8 levels: 24/24 XOR empty.
- Full re-bake: 365 maps, 0 missing tiles. Browser audit: 355/365 maps,
133/136 level ids clean (112/124/129: Act 5 minions without art, as
before).
- verify:world-graph 37583 assertions; verify:world-walk 29/29;
verify:entity-packs, typecheck clean. vitest 6369 passed; the 6
failures (5 ground-item name formatting, 123-var3 waypoint) and the
verify:packs / verify:generators failures also occur at bad6806.
Test pins updated, measured on the new bake: SceneEntrance 172 -> 166
and world-graph edges 286 -> 284 (the removed seam), seamless pairs
27 -> 26 and placement pairs 19 -> 18; full-spectrum floors / walls /
PNGs 1008898 / 237542 / 1390 (the old pins matched no bake of the
current code).
