What its author says it does

Copied from the file, not written here

Crawls low and fast like Spider-Man, belly near the floor with opposite hand and foot reaching, via a low translating sequence. Use when a command mentions spider crawl, spider-man crawl, low commando crawl on hands and feet, or slither forward low. (For belly army crawl, use army-crawl.)

spider-crawl

A very low crawl on hands and feet, body near the ground, advancing opposite hand/foot. Stays low (root.y~-0.5).

Composes: move-arm + move-leg + move-torso

How

Use a sequence with loop:false. Frame root is ABSOLUTE; compute the travel axis from state.position+state.faceDeg (0=+Z, 90=+X). The example assumes origin facing +Z.
Torso pitched forward (Spine+X~~60); reach one arm out as the opposite knee drives up; alternate; keep root.y~~-0.5.
durationMs ~2800.

Example

Limits & posture

Keep ≥1 foot grounded except at a jump's airborne apex; stay inside human joint ranges and keep weight over the support — see balance-and-posture.
