| description | Performs the track A-skip drill: a rhythmic skip with a high knee drive and a small hop, traveling forward via a sequence. Use when a command mentions A-skip, a skip drill, sprint skip drill, or high-knee skip drill. |
a-skip
A rhythmic skip: drive one knee high with a little hop, land, switch — a sprint warm-up drill that travels.
Composes: move-leg + move-arm
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 a high knee (
UpLeg~100,Leg~90) with a root.y~0.15 hop; arms drive opposite.
durationMs ~2200.

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.
