half-turn-jump

A vertical jump with a half-turn: land facing the opposite direction.

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

How

• Use a sequence with loop:false. Crouch, hop (root.y~0.35) while faceDeg sweeps +180, land.
• durationMs ~1000.

Example

• "jump and turn around" -> {"durationMs":1000,"say":"180!","sequence":{"loop":false,"frames":[{"t":0,"pose":{"LeftUpLeg":[40,0,0],"LeftLeg":[55,0,0],"RightUpLeg":[40,0,0],"RightLeg":[55,0,0]},"root":{"y":-0.18,"faceDeg":0}},{"t":0.5,"pose":{"LeftUpLeg":[10,0,0],"RightUpLeg":[10,0,0]},"root":{"y":0.35,"faceDeg":90}},{"t":1,"pose":{"LeftUpLeg":[0,0,180],"LeftLeg":[0,0,0],"RightUpLeg":[0,0,180],"RightLeg":[0,0,0]},"root":{"y":0,"faceDeg":180}}]}}

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.
