Cuberto Particles

Quick start

Add css and markup to your project.

You can use particles.scss from demo.

import Particles from './particles';

const demoParticles = document.querySelector('.cb-particles');
const particles = new Particles({
    container: demoParticles,
    itemsSelector: ".cb-particles-item",
});

Frontend dependencies

GSAP (https://greensock.com/gsap/)

Setup demo project

Install

npm install

Start develop server

gulp or gulp serve deploy app and start browsersync server + watchers

Options

parameter	type	default	description
container	HTMLElement or string	null	particles container (required)
itemsSelector	string	[data-particle-item]	particle element selector
observable	bool	true	automatically play/stop movement if the container is not in viewport
observableTarget	HTMLElement	null	another observable element, instead of a container.
observableRefresh	bool	true	automatically refresh particles when container observe.
repeats	number	-1	number of repeats; -1 is infinite
timeScale	number	1	initial timescale
initialSeek	number	1500	seek timeline to time on first start (not used when repeats > -1)
fadeInDuration	number	0.7	duration of fade in (0 disable).
fadeInEase	string	"power1.out"	fade in ease (see gsap easing)
fadeOutDuration	number	0.7	duration of fade out (0 disable).
fadeOutEase	string	"power1.out"	fade out ease (see gsap easing)
yStart	number or function	containerHeight	start y-coordinate
yEnd	number or function	-particleHeight	end y-coordinate
xStart	number or function	undefined	start x-coordinate
xEnd	number or function	undefined	end x-coordinate
ease	string	"none"	particle movement ease (see gsap easing)
duration	function, number or string	gsap.utils.random(5, 10)	duration of each particle (see gsap duration)
offset	function	gsap.utils.random(0, 20)	function that returns time offset of each particle

Methods

const particles = new Particles({
    container: demoParticles,
    itemsSelector: ".cb-demo-particle",
});

// Start particles
particles.start();

// Stop particles
particles.stop();

// Bind observer to target
particles.observe(target);

// Destroy observer
particles.unobserve();

// Speedup to 2x
particles.setTimeScale(2);

// Reverse particles direction
particles.setReversed(true);

// Check is reversed (return bool)
particles.isReversed();

// Get GSAP timeline object
particles.getTimeline();

// Refresh particles
particles.refresh();

// Destroy particles
particles.destroy();
