- Levitate over water, whole: hover stacks on the water-walk surface, so the body rests exactly a yard above the waterline — the reference's own arm undoes the ground snap and descends by max(L−1.0, 0); casting it while swimming launches you clear of the water, because `SetHover(true)`'s handler calls `CMovement::Jump` before it ever sets the flag — a jump that, unlike Space's, is not refused for a hovering body; and aiming below −37° drops the liquid layers out of the walk mask, which is the reference's own way back into the water and the piece whose absence made the mode a one-way door - walking no longer sinks a Levitator: the step-down snap's no-hit leg — right on land, where it is the frame that leaves a ledge — could not see water, since liquid is queried rather than swept, so every walking frame stepped down a cone's worth while the hover climb hauled it back; the arithmetic closes with no free parameters (descent 0.24355 yd a frame, climb 0.11667, net −0.12688 against a measured −0.12687), settling 0.88 yd under the hover line until the keys were released - the pose advances on the PRESENTATION cadence, not the CPU loop: under vsync a frame reaches the eye only on a refresh boundary, but the measured delta absorbs the render thread's back-pressure wait, so two frames shown 16.67 ms apart get advanced 26.4 and 8.0 — the whole skeleton lurching at once, up to 91 of 117 bones past a quarter pixel in one frame; `Time<Virtual>` is re-split to a delta snapped to the estimated refresh with the remainder carried, engaging only while the stream looks vsync'd so a real stall stays visible — found once the jitter meter probed a point at each bone's flesh radius and logged the animation clock beside the wall clock, the two channels it had been blind in - the character doll is a snapshot you edit, not a mirror you follow: the reference re-takes a model widget's copy on becoming visible, a change of dress, a manual sheath toggle or a resize — the combat auto-draw is not one of them, so a bow drawn in combat stays off the character sheet; and a portrait bake now waits for its PIPELINES too, not just its textures — off macOS a cold pipeline variant skips its batch silently, a one-shot still keeps the hole for the session, and which piece goes missing is which variants lost the race: the hair's alpha-key, the body's opaque, a glow card 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.
