Erik 50c0704ada research: complete acclient.exe function map — 70+ identified functions 
Maps decompiled functions to their real AC class::method names by
cross-referencing against ACE's C# physics port. Covers:

- CPhysicsObj (13 functions): Euler integration, velocity, gravity,
  collision dispatch, friction, contact checking
- CMotionInterp (18 functions): full motion state machine including
  jump, movement, velocity computation, motion dispatch
- CLandBlockStruct (7 functions): terrain mesh construction, split
  direction, UVs, water depth, normal lighting
- CLandBlock (6 functions): landblock lifecycle, static object loading,
  cell management, neighbor expansion
- LandDefs (4 functions): coordinate system constants and transforms
- Collision/Transition (13 functions): sphere-polygon intersection,
  ray-plane tests, BSP traversal, walkable surface detection,
  slide/step sphere, main collision loop
- WeenieObject vtable (7 entries): confirmed from call site analysis

Also documents PhysicsObj struct layout (13 fields with offsets) and
MotionInterp struct layout (14 fields with offsets).

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.
