Campaign P Slice P3 item 1. Retail CPhysicsObj::transition (0x00512dc0)
seeds the collision sweep from CPartArray::GetSphere (the Setup's own
<=2-sphere list, each origin+radius scaled by m_scale) via
SPHEREPATH::init_sphere (0x0050c670) -- not from a symmetric two-scalar
(radius, height) capsule reconstruction. The human Setup 0x02000001's
authored spheres are (0,0,0.475) r=.48 and (0,0,1.350) r=.48; the old
reconstruction from (0.48, 1.835) produced (0,0,0.48) + (0,0,1.355), a
5 mm head-center offset the TS-46 register row documented as a residual.
Port:
- SpherePath.InitPath gains a sphere-list overload (ImmutableArray<
FlatCollisionSphere>, scale) sharing a new InitPathCore with the
existing (radius, height) overload, which is now the degenerate
2-scalar case of the same code -- byte-for-byte unchanged, so every
captured-fixture replay (CellarUpTrajectoryReplayTests,
DoorBugTrajectoryReplayTests, CellarLipWedgeTests) keeps passing
unmodified.
- PhysicsEngine.ResolveWithTransition gains optional sphereList/
sphereScale parameters; empty/default preserves the legacy scalar
path for every pre-existing caller.
- LiveEntityMotionRuntimeController.GetSetupMoverShape is a new sibling
of GetSetupCylinder (left untouched) that resolves the Setup's own
sphere list plus Setup-derived step-up/step-down
(CPartArray::GetStepUpHeight/GetStepDownHeight, 0x005180d0/0x005180f0,
x ObjScale, 0.4 m fallback matching the pre-existing literal).
- Threaded through PlayerMovementController (both resolve call sites,
new SphereList property set by PlayerModeController.ApplyStepHeights
and the Headless world projection), RuntimeRemotePhysicsUpdater
(Tick + TickHidden), and RuntimeOrdinaryPhysicsUpdater.TryBegin.
Remote/ordinary step heights are now Setup-derived instead of a
hardcoded 0.4f literal. Projectile and camera-probe sweeps are
untouched (already single-sphere-exact).
- PlayerModeController.ApplyStepHeights also now applies the x ObjScale
multiply to the player's own step heights (previously only the
remote/ordinary paths did), closing an adjacent gap the P3 research
flagged.
Ts46SphereListConformanceTests proves the sphere-list overload sees the
exact dat spheres (not the reconstruction), that the scalar overload is
unchanged, and that ResolveWithTransition's sphereList parameter
actually drives the sweep (a decoy-scalar control pair using a
head-height obstacle sphere).
Register: TS-46 retired (both residuals it named are closed); header
count corrected to 40 active TS rows.
dotnet build + dotnet test (Core.Tests 3991/2 skip, Runtime.Tests
425/0, App.Tests 3968/3 skip, complete solution build) all green.
