Particles.init not returning anything

[Jhon (kiko)]

I'm trying to pause animation with

  var particles = Particles.init({
         // options
       });
  particles.pauseAnimation();

however particles is undefined
the partcicles keep moving/animating

@jhonalino Are you initializing particles.js on window load? Check this fiddle if you need a working example: https://jsfiddle.net/b1b0q42x/
