RIGGING

Pins that follow bones

A pin can follow a bone instead of keyframes of its own: it sits at the bone's joint and moves and turns with it, so the rig bends the artwork. It suits things that bend along their length, like a tail, a sleeve or this worm.

The worm wiggles with its three bones: its pins follow them, without a keyframe of their own.
WHAT YOU’LL MAKE

The worm wiggles with its three bones: its pins follow them, without a keyframe of their own. This one is the real exported SVG, playing.

Step by step

  1. Select the worm

    With the Select tool, click the worm beside the bones lying along it. The bones already wiggle, but they don't carry the worm.

  2. Pick the Pin tool

    Press W. The bones stay on the canvas while the Pin tool is on.

  3. Turn on Bind to bones

    Click Bind to bones in the bar above the canvas. It is there while a layer that takes pins is selected and the scene has bones.

  4. Click each bone

    Click Bone 1, Bone 2 and Bone 3. Each click adds a red pin at that bone's joint, bound to it; clicking a bound bone again unbinds it. Press Esc when you're done.

  5. Play it

    Press Space. The bones wiggle and the worm bends with them: in the Pins section, each pin names its bone instead of a Position.

Good to know. Bound pins work together with ordinary ones on the same layer: add a few more to hold a part still, or to bend it by hand. The Bind tool binds a pin you already have: click the pin, then the bone. A bone inside a pinned group can't take the group's pins, since it already moves the artwork.
