bear-crawl

Crawl on hands and feet (not knees) with the hips up — the athletic bear crawl. A sequence with a moderate root.y drop and forward translation, legs fairly straight.

How

• Use a sequence with loop:false (frame root is ABSOLUTE — z grows; compute forward from state.position+state.faceDeg, here origin facing +Z). Keep root.y ~-0.35 (higher than a knee crawl).
• Hands-and-feet pose: light torso bend (Spine:[30,0,0]), arms to the floor (LeftUpperArm:[90,0,0],RightUpperArm:[90,0,0]), legs only partly bent so the feet stay down (UpLeg:[55,0,0],Leg:[40,0,0] both). Alternate diagonal limbs.
• durationMs ~2200–2600.

Example

• "bear crawl forward" (at x:0,z:0,faceDeg:0) -> {"durationMs":2400,"say":"Bear crawl!","sequence":{"loop":false,"frames":[{"t":0,"pose":{"Spine":[30,0,0],"LeftUpperArm":[90,0,0],"RightUpperArm":[90,0,0],"LeftUpLeg":[55,0,0],"LeftLeg":[40,0,0],"RightUpLeg":[55,0,0],"RightLeg":[40,0,0]},"root":{"y":-0.35,"z":0}},{"t":0.5,"pose":{"LeftUpperArm":[70,0,0],"RightUpperArm":[100,0,0]},"root":{"y":-0.35,"z":0.6}},{"t":1,"pose":{"LeftUpperArm":[90,0,0],"RightUpperArm":[90,0,0]},"root":{"y":-0.35,"z":1.2}}]}}
