strafe-left

Step sideways to its LEFT without turning to face that way. Because the body must keep its heading, this uses a sequence that translates root sideways while OMITTING faceDeg (so the facing holds).

How

• The left of the current facing is the direction faceDeg-90: dx=sin((face-90)deg), dz=cos((face-90)deg). At face 0 that is -X, so root.x DECREASES.
• Use loop:false (frame root is ABSOLUTE — make x step more negative each frame). Do NOT set faceDeg, so the body keeps looking forward.
• Side-step legs: lead with the left leg out (LeftUpLeg:[0,0,150]), then bring the right to meet it (back to rest).
• durationMs ~2000–2600.

Example

• "strafe left" (at x:0,z:0,faceDeg:0) -> {"durationMs":2200,"say":"Sliding left.","sequence":{"loop":false,"frames":[{"t":0,"pose":{"LeftUpLeg":[0,0,150]},"root":{"x":-0.4}},{"t":0.33,"pose":{"LeftUpLeg":[0,0,180]},"root":{"x":-0.8}},{"t":0.66,"pose":{"LeftUpLeg":[0,0,150]},"root":{"x":-1.2}},{"t":1,"pose":{"LeftUpLeg":[0,0,180],"RightUpLeg":[0,0,180]},"root":{"x":-1.6}}]}}
