- picking a spell up off the bar no longer blacks out every empty slot: `UI-Quickslot` is a FILLED 60%-black plate, not a hollow ring (decoded off the shipped BLPs — Quickslot2's interior is RGBA 0,0,0,0, Quickslot's 0,0,0,153), and the reference dims it to half alpha in `ActionButton_ShowGrid`, so an empty well now ghosts at 30% black where it read as a hole; the wow-re cross-check then found the reference never UN-dims it (a 3-argument `SetVertexColor` preserves the current alpha at `0x79abd0`, and `SetNormalTexture` reuses the region), so in the real client the first drag leaves every button's border at half alpha for the rest of the session — benilla ends the dim on purpose and records it as the divergence it is (1782) - the bag bar is the reference's own `MainMenuBarBagButtons.xml` (window 3 of the stock-first migration), and the swap found a real bug rather than a move: the reference's `ItemAnim_OnEvent` matches a push against the button's inventory-slot id (20..23) and benilla emitted its own container numbering (1..4), so all four bag-push cards would have silently never played against the stock body — `push_container` now emits the reference's selector (`bag + 1`), which is what an addon expects anyway; beside it, a readiness probe that asks the LOADER, not a grep, which of the 85 stock windows load off the player's chain today (58 do; the 27 that don't name their own blocker) - a rooted, hovering, water-walking or walking creature reached benilla as an unhandled opcode: the twelve `SMSG_SPLINE_MOVE_*` (the observer twin of the ack'd force family — bare packed guid, no ack, any unit) now decode into one MOVEMENTFLAGS word per unit, which benilla kept for our mover and for a relayed player and not at all for a creature, the one body this family is ever addressed to; ROOT wipes the direction bits so the dead-reckon stops walking a rooted body on for its next heartbeat (`0x7c7340`), HOVER clears a yard off the floor without climbing a body already inside that yard (`0x636e81`), WATERWALK elects the liquid surface against the terrain, SAFE_FALL's terminal is 7.0 not 60.148 (`0x7c5d23`), and SET_RUN_MODE's bool is inverted against the bit, folded at the parse; the inspect card names a unit's granted modes in words (`granted rooted+hover`) so a creature resting a yard off the floor reads as intended rather than broken Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Important
Issues and pull requests are closed here. benilla is a solo project developed in a private tree; this repo is its export, published as squashed snapshots, so a PR here has nothing to land on. The best way to contribute is to join the Discord and report the bugs you find. Questions and ideas are welcome in the same place.
benilla speaks the original 1.12.1 protocol, so it connects to any server the real client could, and reads its game data at runtime from your own 1.12.1 install. Every file format and the network protocol are implemented from scratch, with no original client code, no third-party WoW crates, and no bundled game assets.
What works
- Formats: readers for the full asset stack (MPQ patch chain, BLP, DBC, ADT/WDT/WDL, M2, WMO), wired into Bevy as an asset source.
- World: streamed terrain out to the horizon, portal-culled WMOs with interior lighting, doodads and ground clutter, swimmable liquids, sky and weather, and the client's own day/night lighting, fog and gamma passes.
- Models: GPU-skinned M2s with the full animation controller, a near feature-complete particle system, ribbons, and animated gameobjects from doors to lifts.
- Characters: customization end to end, the armor texture composite, weapons with sheathing and enchant glows, shapeshift forms, stealth and mounts.
- Movement: a WoW-feel controller, networked movement in both directions, the server-granted modes from slow fall to roots, a follow camera with collision, boats, zeppelins and taxi flights.
- Networking: SRP6 auth through world-session crypto, the object mirror into the ECS, and live wire coverage from movement and chat through spells, party, quests, mail, trade, vendors, bank, loot, the auction house and PvP honor.
- UI: a from-scratch FrameXML + Lua engine driving the built-in interface, from the login and
character screens through the full HUD, the classic windows (guild, macros and key bindings
included), chat, nameplates, floating combat text and tooltips; third-party addons load from
a
benilla-config/AddOns/folder beside the executable (partial: AtlasLoot and Bagnon run, see below). - Combat: melee on the faithful swing law, ranged and Auto Shot, casting with GCD and cooldowns, combo points, crowd control that really holds you, and the spell visual pipeline.
- Audio: music, ambience and SFX under the client's own selection and crossfade rules, with interior and underwater transitions and zone reverb.
Where it's going
benilla is done when a 1.12.1 player can do everything here that they could in the original client, it looks and feels the same, and it runs from a download on Windows, Linux and macOS. No dates; the order is what is likely, not a promise.
- Battlegrounds and meeting stones, then the long tail of small features that separates a working client from a finished one.
- Addons, options and performance, ongoing.
- The no-brainer fixes from VanillaFixes, SuperWoW and the like.
- Playable downloads for Windows, Linux and macOS. Linux first.
Not planned: other expansions or client versions, Warden (anticheat).
Running it
You need a 1.12.1 (build 5875) client install for game data, a vanilla server to connect to, and stable Rust. Any 1.12.1 core works; vmangos is what development runs against, and cMaNGOS and the rest speak the same protocol.
WOW_DATA=/path/to/WoW/Data cargo run --release -p benilla
The server defaults to localhost:3724, the stock realmd auth port. Point WOW_HOST
at any IP or hostname, appending the auth port if yours is remapped
(WOW_HOST=play.example.com:5000). Credentials go in at the login screen, or set WOW_USER /
WOW_PASS to skip it.
Early inspiration and file format guidance came from the wowemulation-dev community, and warcraft-rs in particular.
benilla is an independent fan project, not affiliated with or endorsed by Blizzard Entertainment.
It ships no Blizzard content — no art, models, sounds, maps, MPQ contents or FrameXML; you
provide your own legally obtained 1.12.1 client. The interface code under
crates/benilla-app/assets/ui/ is ours, written to the client's own layout and API names so that
the windows look right and 1.12.1 addons find the names they expect.
