Erik 67b51a3e6f fix(anim): implement adjust_motion — TurnLeft/SideStepLeft play backward 
ROOT CAUSE FIX for missing left-side animations.

The AC client's MotionTable has NO cycles for TurnLeft (0x000E),
SideStepLeft (0x0010), or WalkBackward (0x0006). The real client
calls adjust_motion() which remaps these to their right-side
equivalents with NEGATIVE speed before looking up the cycle. Then
multiply_framerate() swaps LowFrame↔HighFrame so the animation
plays backward.

Source: ACE MotionInterp.cs:394-428, decompiled FUN_005267E0.

Changes:
- AnimationSequencer.SetCycle: adds adjust_motion block that remaps
  left→right with speed *= -1 (TurnLeft, SideStepLeft) or
  speed *= -0.65 (WalkBackward = BackwardsFactor)
- LoadAnimNode: when framerate < 0, swaps Low↔High (matching the
  decompiled multiply_framerate)
- GameWindow.UpdatePlayerAnimation: passes original animCommand to
  SetCycle (sequencer handles remapping internally), keeps legacy
  fallback for non-sequencer entities

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.
