Erik b72851a3ee docs(phase-2): refine design after DatReaderWriter spike 
Verified the real GfxObj data shape against DatReaderWriter's generated
types and WorldBuilder's ObjectMeshManager. Three corrections:

- GfxObj.Surfaces is a list and Polygon.PosSurface indexes into it;
  multiple surfaces per GfxObj are the norm. GfxObjMesh.Build now
  returns IReadOnlyList<GfxObjSubMesh> — one sub-mesh per referenced
  surface. StaticMeshRenderer draws entities by grouping entities by
  GfxObj and then by sub-mesh within each GfxObj. Matches the approach
  WorldBuilder takes.

- LandBlockInfo has both Objects (Stabs — small decorations, rocks,
  trees) AND Buildings (BuildingInfo). LandblockLoader loads both
  lists and maps them uniformly to WorldEntity since both types share
  the Frame shape.

- Stab.Frame and BuildingInfo.Frame carry position+orientation only,
  no scale component. WorldEntity.Scale dropped. WorldEntitySnapshot
  loses its Scale field too. Phase 3+ can add it back if needed.

Closes the one open design question flagged in the original doc.

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.
