Proton是一个灵活的html5粒子引擎。他默认支持canvas,dom,webgl,easeljs,pixel五种渲染方式,当然你还可以轻易的自定义自己的渲染器。只需10几行代码就可以打造你想要的粒子效果。
Proton安装
npm install proton-js --save
...
import Proton from 'proton-js';
使用
var proton = new Proton();
var emitter = new Proton.Emitter();
//set Rate
emitter.rate = new Proton.Rate(Proton.getSpan(10, 20), 0.1);
//add Initialize
emitter.addInitialize(new Proton.Radius(1, 12));
emitter.addInitialize(new Proton.Life(2, 4));
emitter.addInitialize(new Proton.Velocity(3, Proton.getSpan(0, 360), 'polar'));
//add Behaviour
emitter.addBehaviour(new Proton.Color('ff0000', 'random'));
emitter.addBehaviour(new Proton.Alpha(1, 0));
//set emitter position
emitter.p.x = canvas.width / 2;
emitter.p.y = canvas.height / 2;
emitter.emit(5);
//add emitter to the proton
proton.addEmitter(emitter);
// add canvas renderer
var renderer = new Proton.CanvasRenderer(canvas);
proton.addRenderer(renderer);
//use Euler integration calculation is more accurate (default false)
Proton.USE_CLOCK = false or true;
