Erik e08a06ac5b feat(physics): Transition.FindTransitionalPosition core algorithm 
Port FindTransitionalPosition, TransitionalInsert, FindEnvCollisions,
AdjustOffset, DoStepDown, ValidateTransition from transition_pseudocode.md.
Outdoor terrain collision with step-down ground contact. Indoor BSP and
object collision deferred to subsequent tasks.

Also adds PhysicsEngine.SampleTerrainZ() which dispatches the terrain Z
query to the right registered landblock by world-space XY position.

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.
