Re: [QUIZ] Space Merchant (#71)
Here is my Galaxy implementation. It seems to do everything it needs to do, but I didn't go overboard with extra stuff since I don't know what kind of stuff might be useful for the Galaxy to do... The easiest way to use this with the GalaxyLoader seems to be to remove the 'require galaxy' from GalaxyLoader and do it the other way around. Then you can run the tests including the dump test with: ruby -rgalaxy_loader galaxy.rb There are some naive benchmarks I used to make the obvious optimizations, run them with: ruby galaxy.rb -bm One additional thing I did consider was multiplayer - it's fairly easy to get a galaxy working over DRb, and I did work up a basic multiplayer version like this but had one overriding problem - all output ends up on the server, or the game ends up useless because of constantly marshalling sectors to send down the wire. I toyed with routing output through the Player but still had problems... Ho hum. Finally, I need to thank a couple of people: Dominik Bathon's solution to Ruby Quiz 31 ( see http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-talk/141783 ) gave me a much-needed start with Dijkstra's shortest path algorithm (in fact it's only very slightly modified from his original) and Mauricio Fernandez's WeakHash class let's me cache stuff irresponsibly (see http://eigenclass.org/hiki.rb?weakhash+and+weakref ) -- Ross Bamford - rosco@roscopeco.REMOVE.co.uk
