Erik 9dbb2cbd5c fix(core): Phase B.3 — add centroid + radius bounds to PortalPlane crossing test 
Portal planes are infinite — IsCrossing only checked if positions
were on opposite sides of the plane, without verifying the crossing
point was near the actual portal opening. Walking 50m from a
building but crossing the same plane extension triggered false indoor
transitions, sinking the player into underground cell floors.

Fix: FromVertices now computes centroid (average of 3 vertices) and
bounding radius (max vertex distance + 2 unit padding). IsCrossing
rejects crossings where both positions are further than 2×radius
from the centroid. Only nearby crossings (within doorway range)
trigger a transition.

Also fixes jump-not-landing: the false portal transitions were
producing wrong resolvedGroundZ values during the jump arc, making
the landing check (candidateZ <= resolvedGroundZ) never true.

283 tests still 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.
