zigzag-run

A quick evasive run that cuts hard left then right while advancing, leaning into each cut.

Composes: walk + turn-and-face + move-torso

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.
• Alternate sharp x cuts with z advancing and faceDeg tipping; lean the torso (Spine Z) into each cut.
• durationMs ~2400.

Example

• "zigzag run" -> {"durationMs":2400,"say":"Zigzag—can't catch me!","sequence":{"loop":false,"frames":[{"t":0,"pose":{"Spine":[12,0,14]},"root":{"x":-0.6,"z":1,"faceDeg":-25}},{"t":0.5,"pose":{"Spine":[12,0,-14]},"root":{"x":0.6,"z":2,"faceDeg":25}},{"t":1,"pose":{"Spine":[0,0,0]},"root":{"x":0,"z":3,"faceDeg":0}}]}}

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.
