How to create snow effects for this Christmas with tsParticles

#javascript #webdev #tutorial #html

Christmas is coming 🎅 and why don't add a snow effect in your website?

Here's a simple guide to add the snow effect using tsParticles.

Demo

Here's a small demo of the effect, if you remove the background options it will be transparent so you can put in your website without changing anything.

Configuration

This is one of the easiest configuration for a nice snow effect. It's not interacting with the mouse events, but it can be achieved easily.

For more options and examples checkout the official website

snow.json

{
   "background":{
      "color":"#000000"
   },
   "particles":{
      "color":{
         "value":"#fff"
      },
      "move":{
         "direction":"bottom",
         "enable":true,
         "outModes":"out",
         "speed":2
      },
      "number":{
         "density":{
            "enable":true,
            "area":800
         },
         "value":400
      },
      "opacity":{
         "value":0.7
      },
      "shape":{
         "type":"circle"
      },
      "size":{
         "value":10
      },
      "wobble":{
         "enable":true,
         "distance":10,
         "speed":10
      },
      "zIndex":{
         "value":{
            "min":0,
            "max":100
         }
      }
   }

{
   // The background color is for making the particles visible since they're white. Remove this section if not needed

      // Some depth to the effect, (the layers count by default is 100, changing max here is not affecting that count)
      // The zIndex will affect speed, size and opacity of the particles/snowflakes, the smaller the zIndex the smaller/more transparent/slower the particles/snowflakes will be

  }
}
Enter fullscreen mode Exit fullscreen mode

Web Components

For adding this effect in any website using Web Components, you just have to add the snow.json file above in your folder, and add this HTML below in your page.

index.html

<web-particles
        id="tsparticles"
        url="snow.json"
/>

<script src="https://cdn.jsdelivr.net/npm/@webcomponents/webcomponentsjs@2.6.0/custom-elements-es5-adapter.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@webcomponents/webcomponentsjs@2.6.0/webcomponents-loader.js"></script>
<script src="https://cdn.jsdelivr.net/npm/tsparticles@1.37.5/tsparticles.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/web-particles@1.10.5/dist/web-particles.min.js" type="module"></script>
Enter fullscreen mode Exit fullscreen mode

jQuery

For adding this effect in any website using jQuery, you just have to add the snow.json file above in your folder, and add this HTML below in your page.

<div id="tsparticles"></div>

<script src="https://cdn.jsdelivr.net/npm/tsparticles@1.37.5/tsparticles.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/jquery-particles@1.37.5/dist/jquery.particles.min.js"></script>
<script>
  $("#tsparticles").particles().ajax("snow.json");
</script>
Enter fullscreen mode Exit fullscreen mode

Presets

For adding this effect in any website using just plain HTML and JavaScript with just a single script and a line of code, a snow preset is also available. Just add this to your website and you'll have a snow effect immediately.

<div id="snow"></div>

<script src="https://cdn.jsdelivr.net/npm/tsparticles-preset-snow@1.22.5/tsparticles.preset.snow.bundle.min.js"></script>
<script>
  tsParticles.load("snow", { preset: "snow" });
</script>
Enter fullscreen mode Exit fullscreen mode

The object { preset: "snow" } is still a complete tsParticles options object, you can still customize everything, just complete the object with your additional configuration, every options added to that object will override the preset default options.

For example:

  tsParticles.load("snow", {
    preset: "snow",
    particles: {
      shape: {
        type: "square"
      }
    }
  });
Enter fullscreen mode Exit fullscreen mode

With this sample, you'll have squared particles/snowflakes instead of the default "circle" value, falling like snow.

You can read more about the snow preset here.
A typo was made in the README.md file of the package, the loadFirePreset should be loadSnowPreset.
It's already fixed in the source code, when the new version will be published everything is going to be fine.

Custom Shape

It's possible also to create a custom shape, like a generated snowflake. This is not recommended since a snowflake is heavy to be generated on the go, use images instead. But if someone wants to try it I'll leave the link below.

https://codepen.io/matteobruni/pen/yLzeMqB

The preview is not added here since it can be heavy to render.

The custom shape code is this:

const deg = Math.PI / 180;

function snowflake(c, n, len) {
  c.save();
  leg(n);
  c.rotate(-120 * deg);
  leg(n);
  c.rotate(-120 * deg);
  leg(n);
  c.closePath();
  c.restore();

  function leg(n) {
    c.save();
    if (n === 0) {
      c.lineTo(len, 0);
    } else {
      c.scale(1 / 3, 1 / 3);
      leg(n - 1);
      c.rotate(60 * deg);
      leg(n - 1);
      c.rotate(-120 * deg);
      leg(n - 1);
      c.rotate(60 * deg);
      leg(n - 1);
    }
    c.restore();
    c.translate(len, 0);
  }
}

tsParticles.addShape("snowflake", function (context, particle, radius) {
  snowflake(context, Math.floor(Math.random() * 3 + 2), radius);
});
Enter fullscreen mode Exit fullscreen mode

And it can be used in any of the configuration above, when used in Vanilla JS, jQuery or Web Components with <script> tags you can just add it before calling the tsParticles.load function.
In all the other case refer to the documentation for the particlesInit or init parameter (some component differs in this property) and the parameter of that function is going to replace tsParticles object when calling .addShape method.

For example, React.js component is going to appear like this:

snowflake.json

{
   "background":{
      "color":"#000000"
   },
   "particles":{
      "color":{
         "value":"#fff"
      },
      "move":{
         "direction":"bottom",
         "enable":true,
         "outModes":"out",
         "speed":2
      },
      "number":{
         "density":{
            "enable":true,
            "area":800
         },
         "value":400
      },
      "opacity":{
         "value":0.7
      },
      "shape":{
         "type":"snowflake"
      },
      "size":{
         "value":10
      },
      "wobble":{
         "enable":true,
         "distance":10,
         "speed":10
      },
      "zIndex":{
         "value":{
            "min":0,
            "max":100
         }
      }
   }
}
Enter fullscreen mode Exit fullscreen mode

snowflakes.jsx

import { useCallback } from "react";
import Particles from "react-tsparticles";
import snowflakeConfig from "./snowflake.json";

const deg = Math.PI / 180;

function snowflake(c, n, len) {
  c.save();
  leg(n);
  c.rotate(-120 * deg);
  leg(n);
  c.rotate(-120 * deg);
  leg(n);
  c.closePath();
  c.restore();

  function leg(n) {
    c.save();
    if (n === 0) {
      c.lineTo(len, 0);
    } else {
      c.scale(1 / 3, 1 / 3);
      leg(n - 1);
      c.rotate(60 * deg);
      leg(n - 1);
      c.rotate(-120 * deg);

      leg(n - 1);
    }
    c.restore();
    c.translate(len, 0);
  }
}

const Snowflakes = () => {
  const particlesInit = useCallback((main) => {
    main.addShape("snowflake", function (context, particle, radius) {
      snowflake(context, Math.floor(Math.random() * 3 + 2), radius);
    });
  }, []);

  return (<Particles id="tsparticles" options={snowflakeConfig} init={particlesInit} />);
