gorilla-walk

A folded-over knuckle walk: hands reach down to the floor, hips high, advancing in lurches.

Composes: move-arm + move-torso + move-leg

How

• Use a sequence with loop:false. Frame root is ABSOLUTE; compute the travel axis from state.position+state.faceDeg (0=+Z, 90=+X). The example assumes origin facing +Z.
• Torso folded deep (Spine+X70), arms down toward the floor (UpperArm X150), knees soft; lurch the hips forward.
• durationMs ~2600.

Limits & posture

Keep ≥1 foot grounded except at a jump's airborne apex; stay inside human joint ranges and keep weight over the support — see balance-and-posture.
