- an attached model's frame rides its wearer's rig: composed as bone-offset-plus-world-root every frame, a helm at Elwynn's ~9500-yard coordinates lands on a 0.98 mm f32 grid (exactly 2^-10 yd) and snaps whole steps against a body that moves exactly — the plumed helm, both pauldrons, the sword and the shield, 0.83 px of hop at a fully zoomed-in close-up; each attachment now holds one rigid palette frame composed in the rig's own space, the world position added back camera-relative in the vertex stage, so nothing on the path is ever a big-plus-small sum — the property the reference keeps by injecting its view matrix once, at the root of the attachment tree - a rider composes through the rig's own frame, not the unit's: `joints_root` re-points at the saddle's seat anchor the moment a character mounts, so reading the host entity's transform would have placed a mounted rider's helm and weapon by the gap between its feet and its saddle — pinned by a test whose seat is offset far enough that the wrong frame misses by 6 yards - the water-walk surface is GROUND, not a post-step clamp: stepping onto water with Levitate up froze the last land velocity in — the mover classified every over-water frame airborne (liquid is queried, never swept) while the clamp reported grounded, so the body ran on at full speed through every key release; the reference has no water-walking code path at all — the flag just ORs the liquid layers into the same swept query that finds terrain — so the surface now feeds the same grounded classification the colliders do, and the clamp stays as the resolve half - `WOW_JITTER`, a motion-jitter meter: the camera, the unit root and the pose sampled every frame as first AND second differences — Δ² tells a slow idle from per-frame noise at two orders' distance — with every reading also in pixels at the subject's own distance, because the same millimetre is 0.03 px across a courtyard and 0.8 px pressed against the camera Co-Authored-By: Claude Fable 5 <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 — 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.
Not built yet
Battlegrounds. Third-party addons are partial: AtlasLoot and Bagnon run, and the addon API fills in as other addons are tried.
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.
