How to use: import matter js into your project import Matter from 'matter-js' import matterjs-boilerplate import { matterBoilerplate } from './MatterBoilerplate' start a matterjs project after one line, de-structuring the constants/variables that we'll need access to in our main project file, passing in width and height parameters let { engine, render, runner, world, mouse, mouseConstraint } = matterBoilerplate(width [int], height [int]) runs all the necessary setup of the engine, render, and runner and abstracts it away from the main file you can access these important variables via the line above ^^ now, you can start adding your physics bodies! let rectangle = Matter.Bodies.rectangle(0, 0, 100, 200) World.add(world, body1)
