Erik 4782532c4b research: indoor transition pseudocode from ACE + decompiled analysis 
Sprint 2 research for indoor transitions. Documents:
- ACE EnvCell.find_transit_cells: sphere-plane + BSP containment
- ACE SortCell/BuildingObj.check_building_transit: outdoor→indoor
- PortalSide semantics and portal polygon plane testing
- Gap analysis: acdream needs CellBSP, BldPortal list, VisibleCells

Key finding: full accuracy requires CellBSP (physics BSP from dat)
for sphere_intersects_cell. Current PortalPlane.IsCrossing is a valid
approximation. ACME's AABB PointInCell is an intermediate option.

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.
