Javier Ramírez will present "Fun with Ruby (and without r***s)" and teach how to program your own games with Gosu. The presentation will introduce Gosu, the game development framework, and Chipmunk, the 2D physics library. It will also cover game design considerations and components of a game development workflow. Attendees will learn how to package Ruby games into executable files using the rubyscript2exe tool to distribute their creations.

Fun With Ruby And Gosu Javier Ramirez
- 1. EuRuKo presents Javier Ramírez (javier@formatinternet.com) * in * Fun with Ruby (and without r***s) Program your own games with Gosu
- 2. the characters Ruby ................. as The Damsel Hardware ............ as The Villain Gosu ...................... as The Hero Chipmunk ........ as The Scientist Rubyscript2exe ........ as Himself
- 3. why games work rest play sleep improve, have fun
- 4. why ruby because i can! less code, less clutter easy to try out
- 5. why me HTML PASCAL / BASIC C/C++ JAVA RUBY ASP DBase LOGO SQL PHP VBasic JavaScript Assembler
- 6. Non-technical considerations concept ● game specs / core design ● gameplay/game mechanics ● balance ● look and feel ● More at “Game Architecture and Design: A New Edition” by Andrew Rollings & David Morris
- 7. Part I what's in a game? (game development 101)
- 9. One ring to rule them all
- 10. Game Development Abstraction 3D games are the same, just harder
- 12. the living game
- 13. Development Components main loop / event loop ● game logic: levels, collisions, AI ... ● stateless images (tiles / models) ● stateful images (sprites / models) ● sound FX and music ●
- 14. Part II when Ruby met Gosu
- 15. about by Julian Raschke and Jan Lücker Gosu ( 고수 ): High Hand - Leader C++ + Ruby Bindings http://code.google.com/p/gosu/ (http://tinyurl.com/euruko-gosu)
- 16. design rationale Bloatfree: Gosu aims to contain everything that is necessary to write a game in clean C++ or Ruby code, yet not much more. Reality-driven: Everything in Gosu exists for the same single reason: It was necessary for an existing project. Nothing was, and will ever be, added out of boredom.

- 19. Gosu::Window
- 20. Gosu::Image load individually or tiled drawing can be rotated / scaled supports z-index can use Rmagick objects
- 21. Gosu::Sample & Gosu::Song full playback control volume, speed, pause, resume, stop, pan looping supported midi are better if converted to XM
- 22. Gosu::Font can be a system font or a file easy to check the real width supports rotation and scaling

- 30. tar2rubyscript by Erik Veenstra RBA file: init.rb => tar + base64 + comments
- 31. rubyscript2exe by Erik Veenstra packages ruby, the script and all dependencies together into an executable file. works on windows, linux, OSx
- 32. rubyscript2exe First Step: it runs the application, checking for all the required gems and scripts, creating a list of dependencies to include in the executable
- 33. rubyscript2exe The “Environment Embedding Executable” gzips all the dependencies and attaches the file to a copy of eee
