- coins ride the cursor: `MoneyFrame.lua`/`.xml` load off the player's chain, and the stock kit reads the cursor's coins at load, so the money cursor — payload mode 2, the copper at `[0xb4e2f0]` — is the engine's: `PickupPlayerMoney` puts coins on the cursor and the purse is never debited, and `CoinPickupFrame.xml`, the shift-click coin dialog nothing of ours had ever answered, joins; wow-re's round then set the law: the pickup raises on a non-number and refuses silently on zero, lost control and more than the purse; `AddTradeMoney` folds the coins into the offer as an absolute `CMSG_SET_TRADE_GOLD` gated on the purse; the send-mail setters and `GetCoinIcon` answer as the bytes do; the coinage-change reflex trims an offer the purse no longer covers; and the four send-mail pickup/drop verbs the stock table names do not exist in 5875, so they are not built (1962, 1965) - the trade window is the reference's own file: `TradeFrame.xml` + `TradeFrame.lua` off the chain, ours deleted; `GameTooltip:SetTradePlayerItem`/`SetTradeTargetItem` (`0x5341e0`/`0x534410`) render the slot's item the way the loot slot's is, and `TRADE_PLAYER_ITEM_CHANGED`/`TRADE_TARGET_ITEM_CHANGED` — which the stock file repaints one slot on, and nothing had fired — fire per changed slot beside `TRADE_UPDATE`; the stock file brings the chain's own `MoneyInputFrame`, a TARGET_TRADE `SmallMoneyFrame`, `ItemButtonTemplate` slots and the enchant slot's own wording — "Item not yet modified" where ours had read "Will Not Be Traded"; the wire's enchant id is not carried into the slot yet, so the tooltip shows the item without its enchant (1966) - the dialogs' verbs, as the bytes define them: nine of the ten stock `StaticPopup.lua` bindings 1960 had left named are built off wow-re's round with their packets, events and UIParent arms — the bare trade pair, `ForceLogout`, the instance-boot timer (whole seconds), the area spirit healer's accept/cancel/time, `AcceptBattlefieldPort` out of a three-slot queue `SMSG_BATTLEFIELD_STATUS` fills, `CancelMeetingStoneRequest`, and the pet trainer's pair as the talent wipe's twin, latch for latch — `SMSG_PET_UNLEARN_CONFIRM` latches and asks, `ConfirmPetUnlearn` sends behind the money gate, `CheckPetUntrainerDist` reads the leash; not built, named: the healer's proximity scan (`0x4923b0`: 20 yd to acquire, 22 to retain), so no healer is cached yet, and `ReplaceTradeEnchant`, which rides trade-slot enchant targeting this engine does not build (1963) - the scrolling combat text is the reference's own `Blizzard_CombatText`, LoadOnDemand off the chain: our transcription is deleted, and the addon loads through `UIParentLoadAddOn` at the reference's own sites; the family's fourteen defaults move to the options file where the reference keeps them, because a LoadOnDemand addon cannot define the options that decide whether it loads (1964); and the Looking-for-Group pair is what the bytes define, correcting 1959's flag: `SetLookingForGroup` takes three (type, entry) pairs and a comment, packs each slot as `(type << 24) & entry` — an AND (`0x4e9713`), so every admissible input stores zero — and sends `CMSG_SET_LOOKING_FOR_GROUP` only when the commit changed something; `GetLookingForGroup` answers three nilable slot names then the comment, never 1|nil; and the stock 1.12.1 UI never calls either — both call sites sit in an XML comment (1961) 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.
