hosted on GitHub Pages, although given part of our business is selling licenses to portals, they are all located in private repositories.
I’ve created a few tutorials which still seem to be quite popular. Gamedev Canvas workshop is something that can help you learn how to build HTML5 games using the Breakout game as an example, documented on MDN Web Docs as 2D Breakout game using pure JavaScript.
Quack Whack is a WebVR game demo I was using to teach A-Frame at a few workshops, the Gamepad API Content Kit was showcased during a couple of talks I gave, MDN Games 3D was an effort to go through the basics of 3D games on the Web published on MDN Web Docs, and Gamedev Phaser Content Kit contains the tutorial on building a Breakout game using Phaser.
There’s also the js13kPWA app going through the PWA features, which was used as an example in another MDN Web Docs series of articles, the Core PWA guides.
As you can see there’s plenty of little things, but I’m still surprised they were enough to become a GitHub Star.
Still, I do hope at least a few HTML5 game developers will use some of the materials listed above, and will benefit one way or the other!
