Introdution

react-text-fun is a small component library that encapsulates Blotter.js shader materials in the form of React components and provides a very easy to use API.

I created react-text-fun after finding myself imperatively using the Blotter.js APIs for custom and existing materials. I decided to convert all its shader materials in the form of React components to make it easier to work with.

Hope you find it useful as well 🙂

Install

yarn add react-text-fun

This package also depends on Blotter.js so make sure you put the below script in your HTML file.

<script src="https://unpkg.com/blotterjs-fork@0.1.0/build/blotter.min.js"></script>

Example

Let's take an example of distortion text material that distorts the shape of the text using various transforms

import { DistortionText } from 'react-text-fun'
import React from 'react';
import ReactDOM from 'react-dom';

const App = props => (
  <div>
    <DistortionText text="Hello wold" />
  </div>
)

// Assuming you have an element with id 'root' to which you want the component to render to.
ReactDOM.render(<App />, document.getElementById('root'))

If you've followed the installation instructions carefully, you should see this output.

Cool, isn't it?

Check out the API reference for DistortionText component to see what other effects you can apply to the text.

Blotter components

Distortion Text

Distortion text is based on the Rolling Distort Material in Blotter.js.

Example

import { DistortionText } from 'react-text-fun'

<DistortionText
  speed={1.5}
  rotation={45.0}
  distortX={4.9}
  distortY={6.5}
  noiseAmplitude={0.8}
  noiseVolatility={1.2}
/>

While it's a good practice to change the values of these props and see the result, I'll still recommend reading this brilliant piece written by Josh Comeau on Waveforms. It will give you a little more idea on how and what values you should use to update the noise amplitude and its volatility.

Flies Text

Flies Text component is based on the FliesMaterial in Blotter.js

import { FliesText } from 'react-text-fun';

<FliesText
  cellRadius={0.5}
  cellWidth={0.012}
  speed={2}
  dodge={true}
  dodgeY={0.35}
  dodgeSpread={3.5}
/>

Split color channel

Split color channel is based on ChannelSplitMaterial in Blotter.js

import { SplitColorChannelText } from 'react-text-fun';

<SplitColorChannelText
  rotation={85.0}
  rgbOffset={2.8}
  addBlur={false}
  addNoise={true}
/>

Liquid distortion text

import { LiquidDistortionText } from 'react-text-fun';

<LiquidDistortionText
  speed={0.6}
  volatility={2.4}
/>

Styling text

You can use the below props with any of the above component to style the text. These are the common props.

Using text canvas

You can also access the canvas which renders the text using the callback function get2dContext. As the prop name suggests, the callback function receives the 2D rendering context for the drawing surface as an argument. This is useful if you want to update the canvas using any other third party library.

get2dContext can be used with any of the above material components. For instance, here is an example of how you would use it with FliesText component.

<FliesText {...props} get2dContext={ctx => console.log(ctx)} />
