I love this stuff. Programmers at my office had a Robocode melee competition that ran every week for a month. Grand prize was an extra vacation day. It was so much fun I started working on a JS version thinking it would be a good learning tool for JavaScript. I dropped the idea about a year ago but now I want to pick that back up again. Here's an example view of where I left off. The battling javascript even had a function for taunting and responding to hits. http://www.jellyrobotics.com/2013/01/16/code-wars/
