    Proton

    See the detailed documentation please visit here

    Proton is a lightweight and powerful javascript particle engine. With it you can easily create countless cool effects.

    Check out examples at: http://a-jie.github.io/Proton/

    Features

    • Seven kinds of renderers
      • canvas - CanvasRenderer
      • dom - DomRenderer
      • webgl - WebGLRenderer
      • pixel - PixelRenderer
      • easeljs - EaselRenderer
      • pixi.js - PixiRenderer
      • custom - CustomRenderer
    • Create cool effects like the demo of 71squared's ParticleDesigner in 10 lines of code.
    • Integratable into any game engine.
    • Veriety of behaviors which can simulate many different physical effects.
    • Three kinds of emitters and can be easily expanded.
    • The 3D version of the proton engine is here https://a-jie.github.io/three.proton/

    Installation

    Install using npm

    anix

    npm install proton-js --save
    ... 
    import Proton from 'proton-js';
    

    OR include in html

    <script type="text/javascript" src="js/proton.min.js"></script>
    

    Usage

    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;
    

    Description

    Proton.Span (or Proton.getSpan) is a very important concept of the Proton engine, it's everywhere. If you understand its usage, you can create almost any desired effect!

    Proton has now been upgraded to the v3 version. Performance has been greatly improved and api also has some improvements. For more details, please check here.
