Erik 78d43a0914 fix(core+app): slope gradient compensation for feet clipping 
The triangle-aware Z sampling from the previous commit produces exact
terrain-surface Z values, but a point-sampled Z on a tilted surface
places the character's center on the surface while their feet (which
extend horizontally) clip into the rising terrain ahead/behind.

Fix: in PlayerMovementController, sample Z 1 unit ahead in the walk
direction and add 40% of the gradient as an upward bias. This
compensates for the character's collision cylinder radius on slopes
while producing zero bias on flat ground. The bias is applied in the
movement controller (gameplay concern) not in TerrainSurface.SampleZ
(which stays exact for physics/tests).

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.
