Subject: alternate to case; generating a list of sub-classes

The below uses pseudo-random number generation to populate an array
with various monsters, all inherit from Creature.  Can a list of
classes which inherit from Creature be generated automagically?  There
must be a better technique to fill the array then the case
statement...


C:\code>
C:\code>
C:\code>type Driver.rb
require 'ArrayOfCreatures'

require 'Creature'
require 'AssistantViceTentacleAndOmbudsman'
require 'Dragon'
require 'DwarvenAngel'
require 'TeethDeer'



puts "\nquantity of creatures:"
numOfCreatures = gets.chomp.to_i


someCreatures = ArrayOfCreatures.new


0.upto(numOfCreatures) do |i|

        creatureType = Kernel.rand(4)

        case creatureType
        when 0
                someCreatures[i]=AssistantViceTentacleAndOmbudsman.new
        when 1
                someCreatures[i]=Dragon.new
        when 2
                someCreatures[i]=DwarvenAngel.new
        when 3
                someCreatures[i]=TeethDeer.new
        end
end

someCreatures.toString
