Erik 14b0a6e2b8 feat(physics): CylSphere collision for trees, rocks, NPCs
Most scenery objects (trees, rocks) use CylSphere collision from
their Setup, not PhysicsBSP. Register these in ShadowObjectRegistry
with a Cylinder collision type. FindObjCollisions now handles both:
- BSP: full polygon collision via BSPQuery (buildings, stabs)
- Cylinder: radial + vertical cylinder-sphere test (trees, NPCs)

Diagnostics showed 170 CylSphere entities vs 278 BSP entities in
the Holtburg landblock alone — this roughly doubles collision coverage.

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.
