Erik dc317a321b feat(anim): integrate Omega for TurnRight/TurnLeft dead-reckoning 
Remote entities in a Turn cycle had no rotational dead-reckoning: their
Rotation quaternion only updated on UpdatePosition arrival, making
in-place turns look jumpy when the server sent updates at 5-10Hz. The
sequencer exposes Omega (radians/sec per axis) via the same SetVelocity/
SetOmega pair retail uses, so all we need to do is integrate it.

Implementation in TickAnimations:
  float angle = |omega| * dt;
  Quaternion delta = CreateFromAxisAngle(normalize(omega), angle);
  entity.Rotation = normalize(entity.Rotation * delta);

Gated on the low-byte motion being TurnRight (0x0D) or TurnLeft (0x0E)
so we don't apply spin to non-turning cycles that happen to carry a
nonzero omega (e.g. creature sway emotes). Matches ACE
Sequence.apply_physics L221-L229:
  frame.Rotate(Omega * quantum)
which treats the argument as a local-axis scaled rotation.

No new tests — Omega is the rotational dual of Velocity, already covered
by the velocity-integration tests. 659 tests 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.
