Baku provides a simple Entity Component System framework for use with Ruby game engines. It has been tested with Gosu, but should be flexible enough to work with any Ruby project that has a game loop.

Baku is still very much a work in progress. There are undoubtedly bugs. I will be continually iterating and improving on it as I use it for my personal game development projects. Enjoy!

The Baku wiki includes a quick start guide if you're already familiar with the ECS approach. If not, there is also a descriptive tutorial that will cover ECS concepts while walking you through setting up Gosu with Baku.

Add this line to your application's Gemfile:

gem 'baku'

And then execute:

$ bundle

Or install it yourself as:

$ gem install baku

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Bug reports and pull requests are welcome on GitHub at https://github.com/jtuttle/baku.
