SamandClaude Fable 5 31706821cd the combat log's wire completes, and PlayerModel is its own class
- the combat log's last eight wire bodies decode — PARTYKILLLOG, SPELLINSTAKILLLOG, PROCRESIST, SPELLORDAMAGE_IMMUNE, SPELLDISPELLOG, DISPEL_FAILED, ENCHANTMENTLOG, SPELLLOGEXECUTE — each layout read off vmangos's own writer and pinned by a byte-exact golden (DISPEL_FAILED carries no count, the list runs to the end of the body; SPELLLOGEXECUTE's POWER_DRAIN row is (amount, power, multiplier), verified at the client's bytes as well as the server's); with the eleven chat types that were waiting on them, 44 chat types become 55 — 29 sentence families, the death pair and the aura rows riding descriptor diffs because 1.12 has no "unit died" opcode, plus the six trailers ((glancing), (30 blocked), (12 absorbed) and kin) that had been missing from every family; also corrected: the durability-death line was going to the red error frame with hard-coded English, and SMSG_SPELLNONMELEEDAMAGELOG lacked its split-damage branch and its blocked wording
- PlayerModel is its own frame kind: SetUnit, RefreshUnit and SetRotation were published on Model, but they belong to the <PlayerModel> method table (0x84f1fc), and the client's lookup chains derived → base only, so a plain <Model> can never reach them — they got there from a strings scan read as ownership, and a strings hit answers whether a name EXISTS, not who owns it (SetUnit's one pooled string is referenced by the PlayerModel and GameTooltip tables and by no Model entry); the new PlayerModel → Model → Frame → Region chain unblocks CreateFrame("PlayerModel"), which is how pfUI builds every unit-frame portrait — and through pfUI, pfQuest and ShaguDPS
- a nil where a number goes is four shapes, not one law: a census of all 408 widget-registrar entries found 62 numeric positions that validate-or-raise, 43 that gate then stage an alternate, 64 that silently coerce to 0.0 and 5 that gate then store nothing — so SetMaxLetters(nil) completes and stores 0, "no limit" (the argument COUNT is checked exactly, the type is not), and the backdrop colour setters are asymmetric on purpose: a nil r/g/b channel is 0.0 but a nil alpha is OPAQUE, and reading every nil as 0.0 would have turned those borders transparent; both setters now also quantize ×255 into the packed 0xAARRGGBB byte quad the client actually stores, so 0.09 reads back as 23/255
- two more addon-killers: LIGHTYELLOW_FONT_COLOR_CODE was the one missing line of Fonts.xml's seven-line colour block (aux-addon concatenates it at file scope and died on its own first line), and the guard now enumerates the whole block l.4-20 instead of the names an earlier round had noticed absent; and the unit frames publish the reference's names — 1.12 has no *PowerBar anywhere, every bar is ManaBar and the colour table is ManaBarColor (8 of the top-20 addons read it by name), so ManaBarColor is the published table our own bars index into, with 22 more regions renamed to the reference's own

benilla

A from-scratch World of Warcraft 1.12.1 client in Rust and Bevy

Discord YouTube devlog License

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.

  • The rest of the basics: battlegrounds, guild charters, the stable master, meeting stones, GM tickets, master loot, cinematics and whatever else turns up.
  • 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.
