Subject: Re: Text Based RPG in Ruby

Hi there Hugh,

I'd previously taken a look at Dwemthy's array (Poignant Guide to Ruby 
right) and it is undoubtedly a nice implementation of a text-based RPG 
in Ruby. My problem is that I'm extremely stubborn and even lifting a 
line of code makes me feel dirty.

I want this program to be 100% written by me. I know that doesn't stop 
me learning from others but I often end up writing code that is far too 
similar for my liking!

Also on a slightly embarassing note, my ruby skills are not to the level 
where I can easily understand snippets such as:

 define_method( :initialize ) do
      self.class.traits.each do |k,v|
        instance_variable_set("@#{k}", v)

or   def self.metaclass; class << self; self; end; end

  def self.traits( *arr )
    return @traits if arr.empty?

    attr_accessor(*arr)

    arr.each do |a|
      metaclass.instance_eval do
        define_method( a ) do |val|
          @traits ||= {}
          @traits[a] = val

And so my code is far less efficient and rather ugly too :(

Thanks for the link though!

Kind Regards,

Ruairidh McHardy
