Subject: class method defined, still undefinded method exeption

Hi

i try to untangle tightly coupled classes. To that end theres a class to
hold all resources that are needed by multiple other classes. Its called
RA for Resource Aggregator.

Moving one central object to that class broke the programm. Here's the
output:

./video.rb:11:in `initialize': undefined method `screen' for RA:Class
(NoMethodError)
  from ./game.rb:32:in `new'
  from ./game.rb:32:in `initialize'
  from ./resourceaggregator.rb:10:in `new'
  from ./resourceaggregator.rb:10
  from ./main.rb:3:in `require'
  from ./main.rb:3

RA is pretty big, so i ommit most Methods. Its intended to be a utility
class and has no custom initialize:

class RA
  @@xRes = 1280
  @@yRes = 800
  @@colordepth = 16
  @@screen = SDL.setVideoMode(@@xRes, @@yRes, @@colordepth,
SDL::SRCCOLORKEY) #SDL::FULLSCREEN
  @@game = Game.new
  @@videoManager = VideoManager.new
  ...
  def self.screen
    @@screen
  end
end

Here is initialisite from VideoManager

def initialize
  @screen = RA.screen
  @xOffset = 0
  @yOffset = 0
end
