army-crawl

Stay flat on the belly and drag forward — the lowest crawl, for going under things. A sequence with a deep root.y drop and a slow forward translation.

How

• Use a sequence with loop:false (frame root is ABSOLUTE — z grows slowly; compute forward from state.position+state.faceDeg, here origin facing +Z). Keep root.y very low (~-0.8).
• Prone pose: deep torso bend (Spine:[45,0,0],Chest:[25,0,0]), arms reaching ahead (LeftUpperArm:[90,0,0],RightUpperArm:[90,0,0]), legs splayed low (UpLeg:[40,0,0],Leg:[60,0,0] both). Alternate arm/leg pulls.
• Slow durationMs ~2800–3400.

• "army crawl forward" (at x:0,z:0,faceDeg:0) -> {"durationMs":3000,"say":"Staying flat.","sequence":{"loop":false,"frames":[{"t":0,"pose":{"Spine":[45,0,0],"Chest":[25,0,0],"LeftUpperArm":[90,0,0],"RightUpperArm":[90,0,0],"LeftUpLeg":[40,0,0],"LeftLeg":[60,0,0],"RightUpLeg":[40,0,0],"RightLeg":[60,0,0]},"root":{"y":-0.8,"z":0}},{"t":0.5,"pose":{"LeftUpperArm":[70,0,0],"RightUpperArm":[100,0,0],"LeftUpLeg":[55,0,0],"RightUpLeg":[25,0,0]},"root":{"y":-0.8,"z":0.5}},{"t":1,"pose":{"LeftUpperArm":[90,0,0],"RightUpperArm":[90,0,0]},"root":{"y":-0.8,"z":1}}]}}
