Echo Trail

Paste it into your composition

Open compositions/components/echo-trail.html and copy what is inside into your own composition.A component has no size or duration of its own. It takes both from the composition you paste it into.

Variables

Every one of these has a default, so the piece works untouched. Set the ones you want to change on the element:

Variable	Default	Accepts	What it does
`echoes`	`4`	number	Ghost copy count, clamped 2 to 6.
`delta`	`0.09`	number	Lag between successive ghosts in seconds, clamped 0.03 to 0.3.
`path`	`sweep`	`sweep`, `rise`, `arc`	Authored traversal preset.
`accent`	`green`	`green`, `blue`, `violet`	Subject accent color: green rides —brand, blue rides —accent, violet rides —accent-2.
`exit`	`none`	`none`, `fade`, `up`	Optional departure. Default none: the settled element holds until the frame cuts.

Set them with data-variable-values on the element that mounts it. These are the defaults, so this behaves exactly like the preview above until you change one:

<div
  data-composition-id="echo-trail"
  data-composition-src="compositions/components/echo-trail.html"
  data-variable-values='{"echoes":4,"delta":0.09,"path":"sweep","accent":"green","exit":"none"}'
></div>
