- the world camera's pick regression: its off-screen render target carried `scale_factor: 1.0`, so on a Retina display the camera reported physical pixels as logical and a centred cursor cast its pick ray into the upper-left quadrant — unit and GameObject picks, the occlusion ray, chat bubbles and `world_to_viewport` all broke at once; the target now carries the window's real scale factor, re-stamped when dragging between displays changes it mid-session — and the perf pill's overlap dodge had the same disease in miniature (`GetBottom()` answers in WoW UI units, the pill lays out in window px), so it now answers a fraction of the screen and works at any window height - `boothHalfRate` defaults back to half-rate: a body pane's off-screen booth pass rendered every frame reads +7.6 ms of GPU at 4K (~1.6 ms at 1600×900), on exactly the weak GPUs that felt the last snapshot — the doll's item effects keep full speed, since they key on the pacing regime rather than the camera's active bit, so only the 30 fps animation cadence returns, and full-rate stays one `SetCVar` away - a spell cast by a GameObject arrives with caster guid 0 — vmangos writes the caster slot from a `Unit*` its GameObject constructor never sets — and the whole visual body was dropped at the guid lookup; the decode now reads an empty caster slot as the packet's first guid, which with no cast item IS the caster, so the Lightwell's click plays its impact kit (sound 3155 and the head flash) instead of only the aura glow that hid the miss, and the object stops being mislabelled a cast item - the world map's black hairlines: a `SetTexCoord` crop is not a texture, and a POI icon magnified to 2.08 px per texel sampled half a texel past its crop into the neighbouring atlas cell — an opaque black row bleeding over a cell that is fully transparent (the empty cell is the reference's own zone-level substitution); `UiQuad::uv_clamp` now insets the sampling window half a texel per axis, so a crop renders as if its sub-rect were its own clamped texture, and `WOW_UI_PICK=x,y` names every quad under a pixel — it found this one in a single run 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.
