Erik 874bcc8690 feat(physics): retail-faithful collision system port from ACE 
Replace the patched collision system (~60-70% retail) with a faithful
port of ACE's BSPTree/BSPNode/BSPLeaf/Polygon collision pipeline.

BSPQuery.cs completely rewritten (1808 lines):
- Polygon-level: polygon_hits_sphere_precise (retail two-loop test),
  pos_hits_sphere, hits_sphere, walkable_hits_sphere, check_walkable,
  adjust_sphere_to_plane, find_crossed_edge, adjust_to_placement_poly
- BSP traversal: sphere_intersects_poly, find_walkable, hits_walkable,
  sphere_intersects_solid, sphere_intersects_solid_poly
- BSP tree-level: find_collisions (6-path dispatcher), step_sphere_up,
  step_sphere_down, slide_sphere, collide_with_pt, adjust_to_plane,
  placement_insert

PhysicsDataCache.cs: Added ResolvedPolygon type with pre-computed
vertex positions and face planes (matching ACE's Polygon constructor
which calls make_plane() at load time). Populated at cache time to
avoid per-collision-test vertex lookups.

TransitionTypes.cs: FindObjCollisions rewritten to use the retail
per-object FindCollisions 6-path dispatcher instead of the old
"find earliest t, then apply custom response" approach. BSP objects
now go through the same collision paths as indoor cell BSP.

The previous approach was explicitly rejected by the user after ~10
iterations of patches. This port follows the CLAUDE.md mandatory
workflow: decompile first → cross-reference ACE → port faithfully.

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.
