An in-progress JRuby port of notch's 48 hour "Ludum Dare" game competition entry

One thing I was taken back by while watching Notch coding (besides his incredible productivitiy) was that all of his code was super-simple... no crazy tricks (besides some nice bit-twiddling), no weird data structures, no language-specific magic: I don't know much Java but I understood every single thing he did! That's awesome.

In fact, the source code is so straightforward that I think you could almost automatically generate the game in other languages!

I'm really disappointed in myself for not taking advantage of watching him code. Seeing the source code is one thing, but it's another to watch someone work. I learned a lot from pair-programming with others, so I can't imagine why I didn't see the utility in this.

However, it has inspired me to dissect his code and learn from it, and hopefully be ready to submit my own entry in the next one. I imagine I'll need to put a lot of practice in before then so I can be ready to code an entire game in 48 hours.

Any tips are welcome!

Very nice, good work Peter! It crossed my mind too when I peeped Notch code (was a bit addictive) to try port it in jruby, as it was as already mentioned a very explicit Java implementation.

The FPS was higher than I expected it to be, for a script language that is. :)

jruby is getting better everyday. :)
