hop-and-turn

A small two-foot hop that rotates the heading partway (e.g. 90) and lands facing the new way.

Composes: bend-knees + turn-and-face + move-leg

How

• Use a sequence with loop:false. Crouch (root.y~-0.15), hop (root.y~0.3) while faceDeg turns ~90, land.
• durationMs ~900.

Example

• "hop and turn" -> {"durationMs":900,"say":"Hop, turn!","sequence":{"loop":false,"frames":[{"t":0,"pose":{"LeftUpLeg":[35,0,0],"LeftLeg":[50,0,0],"RightUpLeg":[35,0,0],"RightLeg":[50,0,0]},"root":{"y":-0.15,"faceDeg":0}},{"t":0.5,"pose":{"LeftUpLeg":[0,0,180],"LeftLeg":[0,0,0],"RightUpLeg":[0,0,180],"RightLeg":[0,0,0]},"root":{"y":0.3,"faceDeg":90}},{"t":1,"pose":{"LeftUpLeg":[20,0,0],"RightUpLeg":[20,0,0]},"root":{"y":0,"faceDeg":90}}]}}

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.
