Erik 3c3f5267de docs(plan): Phase 4 networking design
Design-only doc covering the networking subsystem needed to bring
the static Holtburg scene online: UDP packet codec, ISAAC keystream,
fragment reassembly, GameMessage dispatch, WorldSession lifecycle,
and composite IGameState so server CreateObject messages flow through
the same IEvents pipeline the dat-hydrated static entities already use.

Also documents that ACE is the authority for the protocol (neither
WorldBuilder nor ACViewer implements client networking) and captures
the license hygiene plan: read ACE's AGPL source for protocol knowledge,
reimplement from scratch, credit in NOTICE.md.

Explicit win condition for Phase 4: the foundry statue finally appears,
because it's a server weenie, not a dat decoration.

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.
