const scene = new Scene({
container,
width: 600,
height: 600,
})
const layer = scene.layer('fglayer')
const proton = new Proton()
const 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 = layer.canvas.width / 2
emitter.p.y = layer.canvas.height / 2
emitter.emit(5)
// add emitter to the proton
proton.addEmitter(emitter)
// add canvas renderer
const renderer = new ProtonRenderer(layer)
proton.addRenderer(renderer)
// use Euler integration calculation is more accurate (default false)
Proton.USE_CLOCK = false
