Erik 120e801ecf feat(net+core): Phase 6.2 — honor server CurrentMotionState for idle pose 
CreateObject's MovementData was being skipped past, so the renderer
always fell back to the MotionTable's default style/substate. That's
correct for most NPCs and characters but wrong for entities the
server explicitly puts into a non-default stance — most visibly the
Foundry's Nullified Statue of a Drudge, which the server sends with
a combat stance + Crouch ForwardCommand override and which therefore
rendered as an upright drudge instead of the aggressive crouched
statue you see on the retail client.

CreateObject.TryParse now extracts ServerMotionState (Stance +
optional ForwardCommand) from the inner MovementData. The header=false
layout was confirmed via ACE/.../WorldObject_Networking.cs:326 plus
MovementData.cs::Write and InterpretedMotionState.cs::Write. Only the
two fields the resolver needs are read; remaining InterpretedMotionState
bytes are skipped via the outer length so we don't have to handle
alignment of fields we don't care about.

MotionResolver.GetIdleFrame now takes optional stanceOverride and
commandOverride. Resolution priority is server-stance+command →
server-stance + style-default substate → MotionTable default. If the
composed cycle key doesn't resolve we fall back to the table default
rather than returning null, so a partial server override never makes
the entity worse than Phase 6.1.

160 tests green.

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.
