# Mosswart Massacre for OpenAC
A private OpenAC port of the Mosswart Massacre DECAL plugin: it streams
telemetry, vitals, chat, inventory, combat and character stats to the Mosswart
Overlord backend, shares vitals and debuffs across machines, runs the commands
typed into the Overlord chat box, keeps the flag tracker and syncs metas.
**The backend contract is fixed.** Every frame this plugin sends or accepts is
byte-for-byte what the DECAL plugin sent and accepted; the golden tests under
`tests/` pin each one. Change a frame only together with the backend.
## Building
The plugin contract is `AcDream.Plugin.Abstractions` of the version named in
`Directory.Build.props` (`PluginApiPackageVersion`), currently 0.1.21, the
OpenAC 0.1.21 release. Put that release's package in `packages-local/`; an
OpenAC client from 0.1.21 on loads the plugin.
```
gh release download v0.1.21 --repo eriknihlen/OpenAC -p "AcDream.Plugin.Abstractions.0.1.21.nupkg" -D packages-local
dotnet build OpenAC.MosswartMassacre.slnx
dotnet test OpenAC.MosswartMassacre.slnx
```
## Installing
Copy `src/OpenAC.MosswartMassacre/bin/<config>/net10.0/` (the dll, its
`.deps.json`, `Newtonsoft.Json.dll`, `plugin.json` and the markup) into
`%LOCALAPPDATA%\acdream\plugins\openac.mosswartmassacre\`.
## First run
Streaming is off until you turn it on. The shared secret is never compiled in:
```
/mm ws secret <the backend's shared secret>
/mm ws enable
```
`/mm help` lists every command.
The plugin has one button on the plugin bar, MM. Its Metas tab downloads the
club's metas and navs into the shared VTank profile folder the client
configures (by default `%LOCALAPPDATA%\OpenAC\vtank`), under `mosstank\metas`
and `mosstank\navs`, where MossTank loads them; the tab shows both folders.
## Testing against a stand-in backend
`tools/FrameRecorder` accepts the plugin's socket like the backend does,
records every frame to a JSON-lines file, relays `share_*` frames between
subscribed clients as the backend does, and compares two recordings by
frame shape:
```
dotnet run --project tools/FrameRecorder -- record 18765 frames.jsonl
/mm ws url ws://localhost:18765/websocket/
dotnet run --project tools/FrameRecorder -- compare decal.jsonl port.jsonl
```
## Local peer subscriptions
Requires OpenAC 0.1.21. Combat vital sharing acquires a local state/cast subscription only while enabled, and releases it on disable, logout or unload. Dashboard vitals still stream every five seconds directly from character state without enabling local peer communication. Existing remote WebSocket frames and timing are unchanged.
Before the new contract release exists, pack AcDream.Plugin.Abstractions 0.1.21 from the matching OpenAC checkout and copy its nupkg into packages-local before restore/build. CI downloads that release, so publish the OpenAC contract before dependent plugin releases.
