Modern open-source C# .NET 10 Asheron's Call client. Faithful port of retail client behaviour to Silk.NET with a plugin API.

Before: when the dead-reckoner's prediction and the server's
UpdatePosition disagreed, the hard reassignment caused a visible 1-frame
teleport. Even a small 0.3m prediction error (common when velocity ≠
server's ground truth by a bit) looked like a stutter-step.
Now: on each UpdatePosition, we compute the error
preSnapPos - newServerPos
and stash it as SnapResidual. Each tick the residual decays at
SnapResidualDecayRate (~8/sec, so ~300ms to fade from 1m to 0.05m). The
rendered Entity.Position = authoritative_DeadReckonedPos + residual.
Authoritative position and rendered position are now separated:
- DeadReckonedPos: server truth + velocity*dt integration (used by
clamp logic, collision, shadow registration — anything that needs
accuracy).
- Entity.Position: DeadReckonedPos + SnapResidual (what the camera
sees — smooth blend through prediction errors).
Large errors (> SnapHardSnapThreshold = 5m) are treated as
teleports/rubber-bands and hard-snap with no residual, so a portal
transition doesn't produce a 300ms slow-drift.
No new tests — the visual smoothing is a GPU-side behavior. The
integration tests already cover the authoritative DeadReckonedPos
correctness (via CurrentVelocity scaling + retain-through-link).
659 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 directoryreferences/— 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.
