Erik ae43531866 feat(net): Phase A.3 — background net receive thread
Moves the UDP receive onto a dedicated daemon thread that
continuously pulls raw datagrams from the kernel buffer and posts
them to a Channel<byte[]>. Tick() on the render thread drains the
channel instead of calling _net.TryReceive() directly. All decode,
fragment assembly, ISAAC crypto, event dispatch, and ack-sending
remain on the render thread — this is the minimal change that
prevents packet drops during render-thread stalls without the
complexity of moving decode/dispatch off-thread.

The net thread starts at the end of EnterWorld() after the handshake
is complete — during Connect() and EnterWorld(), PumpOnce() still
reads directly from the socket (the net thread isn't running yet).
Dispose() cancels the thread via CancellationToken, joins with a
2-second timeout, then disposes the socket.

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.
