Erik 97c17c5bc3 fix(app): Phase B.2 — use server position directly, fix yaw wrap + turn spam 
Three more fixes from the diagnostic dump:

1. Initial position: PhysicsEngine.Resolve was mapping the player
   into an indoor EnvCell (foundry at Z=66) when they're standing
   on outdoor terrain at Z=93+. The cell-containment check was too
   aggressive for initial placement. Now uses the server-sent
   position directly — the server already gave us a valid position.

2. Yaw unbounded: mouse delta accumulated without wrapping, growing
   to 24+ radians. Now wraps to [-PI, PI] after every turn.

3. Turn command spam: MouseDeltaX > 0.5 threshold was too low for
   raw pixel deltas. Any mouse jitter triggered turnCmd flips every
   frame → stateChanged=True → MoveToState flood to the server.
   Mouse turning now only affects yaw directly; turn COMMANDS only
   come from A/D keyboard (matching retail client behavior where
   mouse-look doesn't generate a TurnRight/TurnLeft command).

265 tests still green.

acdream

Experimental modern open-source Asheron's Call client in C# / .NET 10.

Status: pre-alpha, not playable. Phase 0 only — dat file asset inventory.

Stack: .NET 10, Chorizite.DatReaderWriter for dat parsing. Silk.NET + Avalonia planned for rendering/UI (not yet wired up).

Requires: A retail Asheron's Call install (Turbine/Microsoft property — supply your own). Set ACDREAM_DAT_DIR environment variable to the directory containing client_portal.dat, client_cell_1.dat, client_highres.dat, and client_local_English.dat, or pass it as the first CLI argument.

Layout

  • src/AcDream.Cli/ — console app that dumps asset counts from a dat directory
  • references/ — local read-only reference material (ACE, ACViewer, WorldBuilder, DatReaderWriter, holtburger, retail AC install). Gitignored.

Run

dotnet run --project src/AcDream.Cli -- "C:\path\to\Asheron's Call"

Or set ACDREAM_DAT_DIR and run without args.
