I really haven’t had a lot of time to spend on new things, I’ve had a lot of personal distractions over the past 2-3 years that have really limited my time and interest in learning new things.
I have however spent a little time looking at HTML5 game engines. Not that I would have time to actually write a game but I always like reading about and experimenting with graphics and HTML5 seems quite suited to that. I only experimented with a few game engines, I looked at quite a few but the two that I found the easiest to use and understand were http://www.kiwijs.org/ and http://www.pixijs.com/.
I spent the most time using pixijs simply because there were enough tutorials and web resources to get a better understanding how the pieces tied together. It’s one thing to write your own engine that you think other people can use, it’s another to actually show people how to use it rather than assume they want to spend hours pulling it apart and actually understanding how things fit together.
Eventually I would like to get back using pixijs and modify the pixelsystems.net logo a the top of this page to make it animated, perhaps some simple 2D effect from the good old Amiga demo/intro days. I’m just surprised how far browsers have gone where you can write a legitimately good looking and fun game in a web based language instead of C++.
