Erik f0fa067566 feat(core+app): Phase 6.4 — per-frame animation playback (breathing/idle cycles) 
Phase 6.1-6.3 resolved the right cycle and rendered its first frame
as a static pose. Phase 6.4 actually walks the cycle over time so
creatures, characters, and props animate their idle motion — the
breathing the user noticed was missing after Phase 6.1.

MotionResolver gains GetIdleCycle() returning IdleCycle(Animation,
LowFrame, HighFrame, Framerate). The existing GetIdleFrame() now
shares a private ResolveIdleCycleInternal helper, so the resolution
algorithm (motion-table override, stance/command priority, fallback)
is identical for both entry points and stays in one place.

WorldEntity.MeshRefs becomes a get/set so the per-frame tick can
swap in fresh per-part transforms without rebuilding the entity.
Static decorations never get touched.

GameWindow keeps a Dictionary<entityId, AnimatedEntity> for entities
whose motion table resolved to a multi-frame, non-zero-framerate
cycle. AnimatedEntity caches a per-part template (gfxObjId +
surfaceOverrides + scale) snapshot taken from the hydration pass so
the tick doesn't redo AnimPartChange/TextureChange resolution every
frame — only the per-part transform matrices are recomputed.

OnRender calls TickAnimations(dt) before Draw. The tick advances each
entity's CurrFrame by dt*Framerate, wraps it inside [LowFrame, HighFrame],
samples the corresponding AnimationFrame, and rebuilds the entity's
MeshRefs by composing scale → quaternion rotate → translate per part
in the same order SetupMesh.Flatten uses, then baking the entity's
ObjScale on top in the same PartTransform * scaleMat order as the
hydration path.

160 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.
