PixiJS Particle Emitter
A particle system library for the PixiJS library. Also, we created an interactive particle editor to design and preview custom particle emitters which utilitze PixiJS Particle Emitter. Note that the editor was built for an older version of the library - to use its output you'll have to use the upgradeConfig()
function.
Breaking changes in v6 from v5
pixi.js
updated to v8- all imports now from 'pixi.js', it is backward compatible but is better to use v5 for pixi.js < v8
- update method of Emitter now have param of type: number | Ticker
- removed LinkedListContainer (for now, development in progress)
- particle performance example is not working as expected now, because LinkedListContainer is not available
- dependencies updated to newer versions (e.g. typescript version now is ^5.0.4)
- examples updated to
pixi.js
v8
Breaking changes in v5 from v4
- Project has been renamed from
pixi-particles
to@pixi/particle-emitter
- On
Emitter
, configuration format has drastically changed. UseupgradeConfig()
to convert old configuration objects automatically. PathParticle
andAnimatedParticle
no longer exist, use the new behaviors instead.- Dropped support for PixiJS v4. Please use v6 - while v5 may work, Typescript definitions won't work and will cause you a headache.
- The library now outputs ES6 code - if you need it in ES5 code, you'll need to make sure your build process transpiles it.
Sample Usage
Please see the examples for various pre-made particle configurations.
// Create a new emitter
// note: if importing library like "import * as particles from '@pixi/particle-emitter'"
// or "const particles = require('@pixi/particle-emitter')", the PIXI namespace will
// not be modified, and may not exist - use "new particles.Emitter()", or whatever
// your imported namespace is
var emitter = new PIXI.particles.Emitter(
// The PIXI.Container to put the emitter in
// if using blend modes, it's important to put this
// on top of a bitmap, and not use the root stage Container
container,
// Emitter configuration, edit this to change the look
// of the emitter

Contributer Note
This project uses yarn
rather than npm
to take advantage of the workspaces feature for the tests, making it easier to have standalone tests that share dependencies where possible.
