Erik 8402aee703 research: full animation pseudocode from decompiled acclient.exe 
Complete pseudocode translation of the retail AC client's animation
system, extracted from chunk_00520000.c. Covers:

- Sequence::update_internal (1021 bytes, the core frame advance loop)
- Sequence::advance_to_next_animation (node transitions)
- Sequence::append_animation (queue management)
- MotionTableManager::PerformMovement (1878 bytes, full state machine)
- AddAnimationsToSequence (transition link → sequence nodes)
- GetStartFramePosition / GetEndFramePosition (reverse playback support)
- AdjustNodeSpeed (negative speed = swapped start/end frames)

Key findings:
- framePosition is a 64-bit DOUBLE, not float
- Negative speedScale swaps startFrame↔endFrame at the node level
- update_internal handles both forward and reverse in one loop
- Frame triggers fire at every integer boundary crossing
- The keyframe slerp lives in the renderer, not the sequencer

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.
