cut-left

Plant the right (outside) foot, drop the hips, and redirect to the left with the heading turning that way.

Composes: walk + shift-weight + turn-and-face

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.
• Plant the outside foot (RightUpLeg abducted) and lean, then drive x negative with faceDeg turning toward the new line.
• Short durationMs (~1100).

Example

• "cut left" -> {"durationMs":1100,"say":"Cut left!","sequence":{"loop":false,"frames":[{"t":0,"pose":{"Spine":[6,0,-10],"RightUpLeg":[40,0,-130],"RightLeg":[60,0,0]},"root":{"z":0.4}},{"t":0.5,"pose":{"Spine":[0,0,8],"RightUpLeg":[0,0,180]},"root":{"x":-0.4,"z":0.6,"faceDeg":-30}},{"t":1,"pose":{"Spine":[0,0,0]},"root":{"x":-1,"z":0.9,"faceDeg":-45}}]}}

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.
