roll
Drop low and roll over sideways, then stand. Since the rig rotates about the vertical axis, the roll is stylized as a low body sweeping root.faceDeg 360° while down.
How
- Use a
sequence with loop:false. Drop root.y low (~-0.7) and tuck the legs (UpLeg:[90,0,0],Leg:[100,0,0] both) with a forward torso; sweep root.faceDeg from the current heading through +180 to +360, then rise (root.y:0, legs to rest).
durationMs ~1400–1800.
Example
- "roll on the ground" (at faceDeg:0) ->
