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

install jruby-head
git clone git://github.com/jwoertink/Waves.git
cd Waves

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. Some examples use space bar, or J and K keys. Read sample file in lib/samples for more info.

OSX 10.8.0+ / Windows 7+

The Nifty-gui must be implemented in Java (for now) to work. This requires taking the lib/samples/nifty/StartScreenController.java and compiling it into the package/classes/java/StartScreenController.class file. If this file is missing, then to compile, run

javac -classpath vendor/jme3_2014-3-31.jar  lib/samples/nifty/StartScreenController.java
mv lib/samples/nifty/StartScreenController.class package/classes/java

• Not tested in any other OS

• Nifty/JRuby example (sample 13a) throws nasty exception

• Rag-doll sample loads, but isn’t useable

• Sample 16 isn’t working

• Sample 17 is missing some stuff

• 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.
