baseball-slide
A figure-4 slide: lead leg extended, trail leg folded under, body leaning back, carrying forward low.
Composes: move-leg + move-torso + balance-and-posture
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.
- Drop and extend the lead leg (
RightUpLeg~85,RightLeg~10) with the trail leg tucked under (folded + turned in), lean back, then recover.
durationMs ~1300.
Example
- "slide into the base" ->

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.
