How to use Cannon.js physics in Spark AR
I’ve recently been playing with physics in Spark AR, and I thought I would share the journey so far. I’ve also made a project and an npm package that might help kickstart your physics exploration.
This is by no means a complete guide to physics engines, but it should be enough to get you started. For my experiments so far, I’ve been using Cannon.js.
The concept
The way I think about physics engines, is that there’s a visual world and a physics world. …
If you’ve spent some time scripting in Spark AR, you’ve probably come across the limitation of one script file per project. This limitation creates a walled environment away from using all the great JavaScript packages that already exist. Using Webpack, we can get around this limitation.
Webpack to the rescue
If you haven’t come across it before, Webpack is a module bundler primarily for JavaScript, but you can also use it for CSS, images and a whole bunch of things.
The part we’re interested in is bundling multiple JavaScript modules into one file. …
