I finally found Railgun Ruby on the web and installed it.

But I cannot find any documentations.

Does anyone have played around with it? Does anyone still have a good documentation about it?

I'd like to have a look at what it can do.


Yours, Joern.

Doesn't look like it. The project appears dead -- links to it's homepage on Rubyforge go nowhere, and there's only a few casual mentions of it around the internet (usually with associated chatter about Rubygame and some naysayers asserting that Ruby isn't suitable for game development -- YMMV).

I wouldn't recommend using a library in this state. Rubygame looks, at least superficially, like a much more viable product than Railgun.

rubygame is for 2d only... I know ruby won't be the best for 3d, but I wanted to play around a little, test some ideas for game engines – Joern Akkermann Jun 29 '11 at 17:44
Ah I didn't realize that you wanted 3D specifically -- you can probably find some generic OpenGL bindings out there. I don't see why Ruby would be inherently unsuitable (that was just hearsay) except perhaps in a lack of robust framework support for games. – Josh Petrie Jun 29 '11 at 18:55

You may checkout ruby Game libraries at ruby-toolbox. (13 projects)

There is list of languages bindings:,_cross-platform,_real-time_3D_engines#Native_and_binded_languages_support

also you may search "3D Game engine with Ruby binding ?" at and "Velocity Reviews > Newsgroups > Programming > Ruby > Ruby 3D" at velocityreviews dot c0m

sorry, some information not so fresh
