Rubik's Cube

A web based Rubik's Cube implementation. The goal of this package was to provide a minimal interface to the rendered Rubik's cube that would allow consumers to implement custom UI elements and build upon the provided functionality.

Features

• 3D rendered Rubik's Cube
• Customizable material and textures
• Exposed Singmaster notation methods
• Configurable rotation speed
• Responsive canvas

Installation

NOTE: Three.js is a required peer dependency of this package. It has purposefully been excluded in order to reduce bundle size and allow the consumer to use their preferred version.

yarn add @curtishughes/rubiks-cube three

npm install @curtishughes/rubiks-cube three

Exports

Default:

• RubiksCube(canvas: HTMLCanvasElement, materials: THREE.MeshBasicMaterial[], speed?: number, width?: string, height?: string)
  • F (clockwise?: boolean, duration?: number): rotate the side currently facing the solver
  • B (clockwise?: boolean, duration?: number): rotate the side opposite the front
  • U (clockwise?: boolean, duration?: number): rotate the side above or on top of the front side
  • D (clockwise?: boolean, duration?: number): rotate the side opposite the top, underneath the Cube
  • L (clockwise?: boolean, duration?: number): rotate the side directly to the left of the front
  • R (clockwise?: boolean, duration?: number): rotate the side directly to the right of the front
  • f (clockwise?: boolean, duration?: number): rotate the side facing the solver and the corresponding middle layer
  • b (clockwise?: boolean, duration?: number): rotate the side opposite the front and the corresponding middle layer
  • u (clockwise?: boolean, duration?: number): rotate the top side and the corresponding middle layer
  • d (clockwise?: boolean, duration?: number): rotate the bottom layer and the corresponding middle layer
  • l (clockwise?: boolean, duration?: number): rotate the side to the left of the front and the corresponding middle layer
  • r (clockwise?: boolean, duration?: number): rotate the side to the right of the front and the corresponding middle layer
  • x (clockwise?: boolean, duration?: number): rotate the entire Cube on R
  • y (clockwise?: boolean, duration?: number): rotate the entire Cube on U
  • z (clockwise?: boolean, duration?: number): rotate the entire Cube on F

Named:

• materials
  • classic: THREE.MeshBasicMaterial[]: the classic Rubik's Cube material (shown in above gif)

Usage

Rubik's Cube is not coupled with any specific framework. However, I have included some examples of how it can be used with a few of the popular frontend frameworks:

React

import React, { useRef, useEffect, useState } from 'react';
import RubiksCube, { materials } from '@curtishughes/rubiks-cube';

function App() {
  const canvasRef = useRef<HTMLCanvasElement>(null);
  const [cube, setCube] = useState<RubiksCube>();

  useEffect(() => {
    if (canvasRef.current) {
      setCube(new RubiksCube(canvasRef.current, materials.classic, 100));
    }
  }, []);

  return (
    <>
      <canvas width="200px" height="200px" ref={canvasRef} />
      <button onClick={() => { if (cube) cube.F() }}>F</button>
      <button onClick={() => { if (cube) cube.F(false) }}>F'</button>
      {/** ... **/}
    </>
  );
}

export default App;

Vue

<template>
  <div>
    <canvas ref="cube" />
    <button @click="() => cube.F()">F</button>
    <button @click="() => cube.F(false)">F'</button>
  </div>
</template>

<script lang="ts">
import { Component, Vue } from 'vue-property-decorator';
import RubiksCube, { materials } from '@curtishughes/rubiks-cube';

@Component
export default class Editor extends Vue {
  private cube!: RubiksCube;

  mounted() {
    const canvas = this.$refs.cube as HTMLCanvasElement;
    this.cube = new RubiksCube(canvas, materials.classic, 100);
  }
}
</script>

Customize material/textures

import * as THREE from 'three';
/* IMPORTANT: Load RubiksCube from the 'core' sub-module to avoid loading unnecessary material assets */
import RubiksCube from '@curtishughes/rubiks-cube/core';

new RubiksCube(canvas,  [
  new THREE.MeshBasicMaterial({ map: new THREE.TextureLoader().load('path/to/texture1') }),
  new THREE.MeshBasicMaterial({ map: new THREE.TextureLoader().load('path/to/texture2') }),
  new THREE.MeshBasicMaterial({ map: new THREE.TextureLoader().load('path/to/texture3') }),
  new THREE.MeshBasicMaterial({ map: new THREE.TextureLoader().load('path/to/texture4') }),
  new THREE.MeshBasicMaterial({ map: new THREE.TextureLoader().load('path/to/texture5') }),
  new THREE.MeshBasicMaterial({ map: new THREE.TextureLoader().load('path/to/texture6') }),
], 100);
