Subject: using a module to create an object

The following runs, which is good.  But, I get these "nil" outputs for 
each object, rather than even the ?hash code? or ?object id? for each 
object.

I get an error if I try to:  save.creature from within the loop.  I'm 
trying to use the module:

thufir@arrakis ~/Desktop/dwemthys $ 
thufir@arrakis ~/Desktop/dwemthys $ ruby db_crud_create.rb 
-- create_table(:creatures)
  SQL (0.011644)   CREATE TABLE creatures ("id" INTEGER PRIMARY KEY NOT 
NULL, "type" varchar(255) DEFAULT NULL, "life" integer DEFAULT NULL, 
"strength" integer DEFAULT NULL, "charisma" integer DEFAULT NULL, 
"weapon" integer DEFAULT NULL) 
   -> 0.1323s
nil
nil
nil
nil
nil
thufir@arrakis ~/Desktop/dwemthys $ 
thufir@arrakis ~/Desktop/dwemthys $ tail db_crud_create.rb -n 5
 
5.times do |index|
        creature = Instantiate.randomCreature
        puts creature.inspect
end
thufir@arrakis ~/Desktop/dwemthys $ 
thufir@arrakis ~/Desktop/dwemthys $ cat instantiate.rb 
require 'dragon'
 
module Instantiate
 
def Instantiate.randomCreature()
 
        creatureType=Kernel.rand(0)
 
        case creatureType
        when 0
                Dragon.new
        when 1
                Dragon.new
        end   #case
end  #makeCreature
 
 
end # Instantiate
thufir@arrakis ~/Desktop/dwemthys $




thanks,
