leapfrog
Plant the hands on the obstacle and spread the legs wide over it, landing beyond.
Composes: move-arm + move-leg + 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.
- Beats: load + reach hands (
UpperArm X~110), legs splayed over the top (abduct ~140, torso forward, root.y~0.45), land to rest.
durationMs ~1200.

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.
