Erik 49c1a9d29e fix(core): resolve AnimData HighFrame=-1 sentinel before filtering cycles 
Diagnostic spawn dump revealed the player character arrives with
`low=0 high=-1 framerate=30.00 partFrames=33`. The -1 is ACViewer's
"play the whole animation" sentinel (see
references/ACViewer/.../Physics/Animation/AnimSequenceNode.cs:96-113
set_animation_id). My Phase 6.1 code used the raw int values, so
the downstream registration filter evaluated `HighFrame(-1) > LowFrame(0)`
as false and threw away every animated entity whose AnimData used the
sentinel — which, from the live dump, appears to be basically all of
them.

MotionResolver.GetIdleCycle now does the same four-step clamp ACViewer
does: -1 HighFrame → NumFrames-1, clamp LowFrame and HighFrame to
NumFrames-1, and collapse to LowFrame if LowFrame > HighFrame. The
IdleCycle carried up to GameWindow is always in terms of real frame
indices the playback loop can step through. Static poses (framerate==0
or single frame after resolution) still skip registration correctly.

168 tests green.

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.
