My JRuby Port of a Game by Minecraft's Creator
Last weekend, hundreds of coders took part in Ludem Dare, a 48 hour game coding contest. Minecraft’s creator “Notch” created a cool little game in Java called Prelude of the Chambered. So far, I’ve spent two days porting it to JRuby. It’s not complete but you can play the first few minutes OK now (get weapon, push rocks, kill bats, etc.) The performance is nowhere near as good as in Java but that’s the next step, so if you’re a JRuby expert, I expect pull requests.. :-)
