SamandClaude Fable 5 7eca017eb0 the Options window goes era, and settings finally persist
- one era-style Options window: window chrome, category list, search box and its own ESC rung, with the game menu reshaped to match
- settings are real CVars now: GetCVar/SetCVar reach Lua, and your changes persist as a diff in benilla/config.toml
- all local state lives in one visible benilla/ folder beside your Data/ — nothing hides in platform config dirs
- UI text stays crisp at any scale and survives a mid-session resolution change: glyphs measure in the environment they raster in

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
and loot.
- **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, chat, nameplates, floating combat
text and tooltips.
- **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
Guilds past the name over a head, the auction house, the hunter and warlock pet bar, battlegrounds
and honor, the fishing minigame, the dressing room, macros and key bindings, and third-party
addons; the Lua engine runs only the built-in UI so far.
## 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](https://github.com/vmangos/core) is what
development runs against, and cMaNGOS and the rest speak the same protocol.
```sh
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](https://github.com/wowemulation-dev) community, and
[warcraft-rs](https://github.com/wowemulation-dev/warcraft-rs) in particular.
