This is just some JRuby( and jMonkeyEngine( fun. Currently these are all samples from the jMonkeyEngine Hello tutorials re-written in JRuby. There are a few small modifications.


(rvm not required, but it's awesome)

rvm install jruby
git clone git://
cd Waves
rvm gemset create @waves
rvm use @waves
gem install bundler

You should be good at this point.


The main application can be run by

jruby bin/waves

You can view other samples by passing the sample number as an argument

jruby bin/waves 8

Normal camera operations use W A S D to move. To exit just hit esc.


OSX (Because I haven't tried this on anything else)
JRuby 1.6+
Bundler gem


Contributing to waves

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet

  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it

  • Fork the project

  • Start a feature/bugfix branch

  • Commit and push until you are happy with your contribution

  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.

  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
