Ruby Bindings to Chipmunk Physics Version 6.1.3 (C) Scott Lembcke, Beoran, John Mair (banisterfiend) and Shawn Anderson (shawn42) IMPORTANT NOTICE: This is version 188.8.131.52 of the bindings for MRI Ruby 1.9.x to Chipmunk version 6.1.3. (1) 1/10/09 Cross-Platform Gem built by John Mair (banisterfiend) * Just go: gem install chipmunk FORUM: http://www.slembcke.net/forums CONTACT: email@example.com (also on Google Talk) for Chipmunk. firstname.lastname@example.org for these bindings to Ruby. ABOUT CHIPMUNK: Chipmunk is a simple, lightweight and fast 2D rigid body physics library written in C by Slembcke. It's licensed under the unrestrictive, OSI approved MIT license. ABOUT THESE RUBY BINDINGS: Although chipmunk comes with ruby bindings, they are not always up to date with regards to the functionality of the C library, and historically, they have been incompatible with recent versions of Ruby. Therefore, these bindings are intended to as an enhanced version with more features and better compatibility with recent versions of Ruby. They are also intended to be an alternative to the chipmunk-ffi bindings when performance is of the utmost importance, as it may be for games. The intent is for these bindings to be mostly source code compatible with the FFI bindings. Main exceptions are when it did not support the functionality I added yet. All this is documented by specs and by the html documentation. If you have any problems with these bindings, please contact the maintainer at email@example.com, or report the issue on the issue tracker: https://github.com/beoran/chipmunk/issues REQUIREMENTS * 1.9.x. * rspec for running the specs. * rake and rake-compiler for compiling the extension. INSTALLATION Clone this repository and do: rake clean compile There is also a gem available for Linux and OS/X, and a binary gem for Windows, which you can try to install with: gem install chipmunk However, due to incompatilties in the latest versions of Rake, Rake-Compiler and rubygems, the gem method of installation may fail for you. This will be solved when these incompatibilities are solved by these upstream tools. These bindings vendor Chipmunk 6.1.3 with a few extra patches, so you don't need to have it installed. DOCUMENTATION: Full handcrafted documentation based on the C documentation is available at: http://beoran.github.com/chipmunk/ CHANGES: * Bumped to Chipmunk version 6.1.3; dropped 1.8 support * Since 184.108.40.206: Vendored chipmunk again, uncleanly. should compile well now. * Version 220.127.116.11 and 18.104.22.168 are broken, don't use them. * Since 22.214.171.124: Vendored chipmunk again, cleanly. Several bugfixes. * Since 5.1.0 : Much more of Chipmunk's functionality is wrapped. Unvendored chipmunk. More specs and documentation. VERSIONING POLICY: Since 126.96.36.199 these bindings follow the version of chipmunk, followed by an extra number for the version of the bindings. All major releases will be backwards compatible in their API. The API may be enhanced in minor releases. KNOWN BUGS: * There are no bindings to SpaceHash since I think they are not so useful anymore since Chipmunk supports BB queries. * Some methods may crash with a segentation violation in case they are not used correctly, according to the underlying requirements of the C library. CONTRACTING: Howling Moon Software (Slembke's company) is available for contracting if you want to make the physics in your game really stand out. Feel free to contact them through their webpage: http://howlingmoonsoftware.com/contracting.php TODO: * Allow several constructors to be more flexible and take nil as a default argument. * Try to prevent segfauts on incorrect use of certain methods, if possible. * Some more specs. * Fix the gem when the upstream tools get fixed.
