The last link is in. AdvanceLegAnimation (@004a5028) and AdvanceBodyAnimation
(@004a5678) reconstructed and wired into Mech::Simulate, and the first live
run put a walking gait on the wire:
before 22 handles, 1 animating (the vehicle root)
after 22 handles, 16 animating, ZERO 2-float records
root 812 poses; six PAIRS at 650/649, 599/596, 563/563,
542/540, 531/529, 434/421; three slow joints at 25
Six left/right pose-count pairs is six joints per leg cycling in alternating
strides -- the symmetry is itself evidence that the handed clip alternation
(Right, Left, Right, each clip one stride) is running correctly. Chain, end
to end, every stage previously verified in isolation and now live together:
mapper demand -> AdvanceLegAnimation (state machine) -> SelectSequence
-> SequenceController::Advance (keyframes -> Joint::SetHinge/SetRotation)
-> BTL4HingeRenderable (5.3.88 matrix transport) -> 12-float flush
-> render bridge applies. Mission drove itself clean, no fault.
RECONSTRUCTED FROM THE RAW DECOMP, NOT THE DONOR -- and the sidecar says why:
BT411's versions carry port-era replicant accommodations (its mapper cell
does not replicate; the binary's does) and a turn-in-place dispatcher it
relocated INTO the leg machine from mech4's master performance. None of that
is 1995 code. Here the leg version reads the mapper unconditionally, exactly
as decompiled, and state 4's ARMING stays where the binary has it -- in
mech4, not yet reconstructed.
THE TWO CHANNELS DIFFER MORE THAN THEIR ClipFinished TWINS DO, all
binary-verified: the leg version has the wind-down block, the turn-in-place
case and the "Standing Not Supported" guard; the body version has none of
those, its case 4 sits in the plain-advance group, and move_joints reaches
every body Advance AND its reset's Reset -- the caller decides whether the
body channel poses joints or only measures stride. Wired accordingly: leg
poses, body measures (move_joints 0), body distance dropped at a seam marked
STAGED -- consuming it as the forward step is IntegrateMotion's job (mech4).
Also faithful: case 0 FALLS THROUGH so a freshly armed clip advances the same
frame it was selected; the plain group's Standing guard is unreachable via
that fall-through and catches direct entry only; each cycle plays its clip at
cycle/stride of the authored rate (a slow walk IS the walk clip played slow);
and the reverse cycle's caps are all negative with the advance ratio folded
positive at the end.
UNSOURCED, named in the sidecar rather than invented: idleStrideScale
(+0x5ac, defaults 1) and runSpeedMax (+0x7a0, the run cycle's upward cap --
LoadLocomotionClips does not set it; defaulted huge so it never binds until
its real writer is found). ForceUpdate(8) is a STAGED no-op pending the
replication emitter.
Still deferred: the airborne Advance* flavours (@004a5bf8/@004a71f4, jump
jets) and the Gimp*ClipFinished limp machines.
