Erik e3f8f95dfc feat(core): port decompiled AC client MotionInterpreter — 10 methods, 45 tests 
C# port of CMotionInterp from chunk_00520000.c — the AC client's
motion state machine that controls walk/run/jump/turn.

Methods ported:
- PerformMovement: top-level 5-case dispatcher
- DoMotion: process raw motion command from packet
- StopCompletely: reset to Ready (0x41000003)
- get_state_velocity: compute velocity for current interpreted state
- apply_current_movement: push velocity to PhysicsBody
- jump: initiate jump (validate + set extent + leave ground)
- get_jump_v_z: vertical jump velocity (delegates to WeenieObj)
- get_leave_ground_velocity: full 3D launch vector
- jump_is_allowed: requires Gravity + Contact + OnWalkable
- contact_allows_move: slope angle + state checks

Supporting types: MotionCommand constants, MovementType enum,
WeenieError enum, RawMotionState/InterpretedMotionState structs,
IWeenieObject interface.

412 total tests (303 core + 109 net). 45 new MotionInterpreter tests.

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.
