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) -> {"durationMs":1600,"say":"Roll!","sequence":{"loop":false,"frames":[{"t":0,"pose":{"LeftUpLeg":[90,0,0],"LeftLeg":[100,0,0],"RightUpLeg":[90,0,0],"RightLeg":[100,0,0],"Spine":[30,0,0]},"root":{"y":-0.7,"faceDeg":0}},{"t":0.5,"pose":{"LeftUpLeg":[90,0,0],"RightUpLeg":[90,0,0]},"root":{"y":-0.7,"faceDeg":180}},{"t":1,"pose":{"LeftUpLeg":[0,0,180],"LeftLeg":[0,0,0],"RightUpLeg":[0,0,180],"RightLeg":[0,0,0],"Spine":[0,0,0]},"root":{"y":0,"faceDeg":360}}]}}
