speed

Controls the global playback rate of all animations managed by the engine.
Values greater than 1 speed up animations, while values between 0 and 1 slow them down.

Adjusting the global playback rate is useful for creating slow-motion or fast-forward effects across all animations simultaneously.

engine.speed = 0.5; // Run all animations at half speed

Accepts

A Number greater than or equal to 0

Default

1

speed code example

import { engine, animate, utils } from 'animejs';

const [ $container ] = utils.$('.container');
const [ $range ] = utils.$('.range');

for (let i = 0; i < 150; i++) {
  const $particle = document.createElement('div');
  $particle.classList.add('particle');
  $container.appendChild($particle);
  animate($particle, {
    x: utils.random(-10, 10, 2) + 'rem',
    y: utils.random(-3, 3, 2) + 'rem',
    scale: [{ from: 0, to: 1 }, { to: 0 }],
    delay: utils.random(0, 1000),
    loop: true,
  });  
}

function onInput() {
  utils.sync(() => engine.speed = this.value);
}

$range.addEventListener('input', onInput);
