perturbation

Randomizes each character's reveal timing for a more organic, less uniform effect. At 0, characters reveal at evenly spaced intervals. Higher values add a random offset to each character's start and end times. At 1, that offset can reach the full settle duration, so characters overlap and settle out of order.

Accepts

Number between 0 and 1

Default

0

perturbation code example

import { animate, scrambleText } from 'animejs';

const [ $p ] = utils.$('p');
const buttons = utils.$('button');

const values = [0, 0.5, 1];

function play(i) {
  animate($p, {
    innerHTML: scrambleText({ perturbation: values[i], cursor: '_________' }),
  });
}

buttons.forEach(($btn, i) => $btn.addEventListener('click', () => play(i)));
