monster-walk
Stay low and wide; step one foot out, then bring the other in — traveling laterally under control. Translate root while OMITTING faceDeg so the heading holds.
Composes: move-leg + bend-knees + balance-and-posture
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. Step x; do NOT set faceDeg.
- Stay in a low half-squat (
Spine+X~14, knees ~60, hips abducted); never let the knees cave.
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.
