I'm planning to write a game for Ludum Dare 42 using SBCL and clopengl. I wrote a simple Asteroids game way back with SDL (https://github.com/andyhd/asteroids), but I haven't had much opportunity to use CL since then. I find Lisp is the most enjoyable language to write in, because it has such minimal syntax, but is incredibly flexible.

I was planning to write about my experience writing this, so I'll keep you posted.

It's really not elegant or special code at all, though, just something I used to learn some more about Lisp.

Thanks!

Thanks for your support! I totally agree with you - I put the code up on Github because I figured someone like me might want to improve it or take it in another direction.

I wasn't trying to write it in less than 600 lines, that's just what the OP used for an interesting title, I guess.

It's just a fun project I did to learn a bit of CL. I translated the code from a Python game, so it's not in pure functional style. Now that you mention it, though, I feel like I should try that.

Thanks for the tip. I didn't realize numbers with the same value could be different to eq.

Hi, author here. I am new to Lisp (about 4 months in) and I've been a happy Vim user for many years, so I'm not finding the transition to Emacs very easy. I am trying, though.

Weird, it was working when I posted. Fixed now.
