Erik a722c29759 feat(physics): re-enable indoor transitions with containment validation 
Sprint 2 of the audit remediation plan.

Re-enables the outdoor→indoor portal transition in PhysicsEngine with
an added containment check: after detecting a portal plane crossing,
verify the target cell's floor polygon actually covers the candidate
position AND the floor Z is within step height of the player's Z.

This prevents the wall-bounce bug (where portal planes on upper
floors captured outdoor positions) while allowing genuine doorway
transitions. Without full CellBSP, the SampleFloorZ + Z-proximity
check is the best available approximation per the indoor transition
research (docs/research/acclient_indoor_transitions_pseudocode.md).

Source: ACE EnvCell.find_transit_cells validates via
sphere_intersects_cell in the target cell's local space. Our
SampleFloorZ + Z check is the equivalent without BSP.

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.
