Final piece of the open-format emit pipeline:
--emit-terrain foo.adt → foo.whm + foo.wot + foo.woc
With this, --emit-open now produces a fully open-format zone
alongside every Blizzard MPQ extraction:
BLP → PNG (textures)
DBC → JSON (data tables)
M2 → WOM (models, with skin merge)
WMO → WOB (buildings, with group merge)
ADT → WHM/WOT (terrain heights + metadata)
→ WOC (collision mesh derived from heights)
Originals stay on disk and indexed by manifest.json so private
servers continue to load proprietary formats; wowee runtime/editor
read the open formats directly. One extraction now feeds both
audiences with no separate conversion pass.
Implementation:
- Inline WHM+WOT writer in open_format_emitter.cpp (mirrors the
editor's WoweeTerrain::exportOpen but without the PNG-preview /
normal-map deps so the extractor stays editor-independent).
- Tile coords (x,y) parsed from <map>_<x>_<y>.adt filename.
- Collision mesh derived via WoweeCollisionBuilder::fromTerrain
(terrain triangles only — WMO collision overlays would need
asset manager and aren't worth the extractor complexity).
Extends asset_extract with two more open-format emitters:
--emit-wom foo.m2 (+ foo00.skin) → foo.wom
--emit-wob foo.wmo (+ foo_NNN.wmo groups) → foo.wob
--emit-open now also turns these on
Originals are preserved so private servers still load .m2/.wmo
through the manifest path; the wowee runtime/editor pick up the
.wom/.wob next to them via the existing open-format search rules.
Implementation:
- New WoweeModelLoader::fromM2Bytes(m2Data, skinData) shares the
conversion body with fromM2(path, am) via a static helper
(convertM2ToWom). Lets the extractor convert without standing
up an AssetManager.
- fromM2(path, am) moved to a separate translation unit
(wowee_model_fromm2.cpp) so asset_extract doesn't have to
link the AssetManager dependency.
- WoweeBuildingLoader::fromWMO already takes a WMOModel directly,
so emitWobFromWmo just needs to read root + group files and
call save().
- Group sub-files (<base>_NNN.wmo) are skipped during the walk
since they're merged into the root WMO.
The asset_extract tool now optionally writes wowee open-format
copies next to each extracted proprietary file:
--emit-png foo.blp → foo.png
--emit-json-dbc foo.dbc → foo.json
--emit-open shortcut for both
Originals are left untouched, so private servers (AzerothCore,
TrinityCore) that load from the manifest's .blp/.dbc paths
continue to work unchanged. The wowee runtime / editor can now
consume the open formats directly without an extra conversion pass.
Implementation:
- New tools/asset_extract/open_format_emitter.{hpp,cpp} encapsulates
the post-extract walk + per-file conversion.
- BLP→PNG uses BLPLoader::load + stbi_write_png with the same
dimension/buffer-size sanity guards the editor's texture exporter
applies.
- DBC→JSON mirrors the editor's DBCExporter::exportAsJson schema
(string/float/uint heuristic) so the runtime DBC overlay loader
can consume the output drop-in.
Drop PROT_EXEC from warden module mmap when using Unicorn emulation
(not needed — module image is copied into emulator address space). Use
MAP_JIT on macOS for the native fallback path.
Add --listfile option to asset_extract and SFileAddListFileEntries
support for resolving unnamed MPQ hash table entries from external
listfiles.
Remove HDPackManager, expansion overlay manifests, and BLP size-comparison
logic. Assets now resolve through a single manifest with a simple override
directory (Data/override/) for future HD upgrades.
Extracts each expansion's assets as a CRC-compared overlay against a
base manifest, storing only files that differ. Auto-detects overlay mode
when a base manifest already exists. Adds --as-overlay, --full-base
flags and manifest merge for partial extractions.
Expansion overlays allow each expansion to supplement the base asset data
via an assetManifest field in expansion.json, loaded at priority 50 (below
HD packs). The asset extractor gains --reference-manifest for delta-only
extraction. Also fixes CharSections field indices (VariationIndex=4,
ColorIndex=5, Texture1=6) across all DBC layout references.
Replace hardcoded WotLK protocol constants with a data-driven architecture
supporting Classic 1.12.1, TBC 2.4.3, and WotLK 3.3.5a. Each expansion
has JSON profiles for opcodes, update fields, and DBC layouts, plus C++
polymorphic packet parsers for binary format differences (movement flags,
speed fields, transport data, spline format, char enum layout).
Key components:
- ExpansionRegistry: scans Data/expansions/*/expansion.json at startup
- OpcodeTable: logical enum <-> wire values loaded from JSON
- UpdateFieldTable: field indices loaded from JSON per expansion
- DBCLayout: schema-driven DBC field lookups replacing magic numbers
- PacketParsers: WotLK/TBC/Classic parsers with correct flag positions
- Multi-manifest AssetManager: layered manifests with priority ordering
- HDPackManager: overlay texture packs with expansion compatibility
- Auth screen expansion picker replacing hardcoded version dropdown
