A simple Asteroids clone, inspired by Square Shooter by No Time To Play, but written in Common Lisp with Lispbuilder-SDL.
I'm learning Common Lisp this year, and it seemed like a fun project. It was.
It's a pun on Abstract Syntax Tree - which Lisp essentially is. Sorry.
I'm afraid you'll need to install Steel Bank Common Lisp and the Quicklisp package tool, which is pretty easy, and then set up Lispbuilder-SDL, which is not. I will write about how I got everything set up on OSX Lion soon.
Assuming you have everything installed, you can simply start SBCL and (load "asteroids.lisp")
and then call (asteroids:main)
from the REPL.
The game is mouse controlled.
A bit rubbish, really. Next steps are learning some OpenGL to make it a bit prettier.
