Argh ok having problems with this. My code has just become very messy 
because I can't get my head clear on this one.

I'm trying to structure the enemy classes as per your advice and so have 
Grunty laid out in a manner similar to this:

class Grunty < Enemy
 def initialize(hp,attack, defense, weapon)
    super(hp, attack, defense)
    @weapon = "AK47"
    @hp =100
    if Grunto.hp  == 0
  puts "Grunty is dead!"
else
  puts "Grunty is wounded but can still fight!"
end
randy = rand(100)
health = Grunto.hp - randy
puts "Grunty's hp is #{Health}"
end

This throws up no errors and although the hit assignment is poor, it 
remains functional.

I then continue to test with an example scenario battle hard coded into 
the script:

Grunty = Grunt.new("hp", 300, 300, "Ak47")
 puts  "Grunty is battling a kitten!"
puts "The kitten attacks Grunty with an AK47 and inflicts #{randy} 
points of damage!"
puts "Grunty lost #{randy} health!"
puts "Grunty's hp is #{Health} "
end
end

In theory this should work but get the following errors:

/home/roo/dev/RubyRPG/RubyRPG/lib/main.rb:19:in `initialize': 
uninitialized constant Enemy::Grunt::Grunto (NameError)
        from /home/roo/dev/RubyRPG/RubyRPG/lib/main.rb:31:in `new'
        from /home/roo/dev/RubyRPG/RubyRPG/lib/main.rb:31
        from :1
        from :1

I'm not too sure why these errors are being thrown up, I assume it's not 
liking the way the class has been edited?

Thanks for all the help so far Stephen, it's helped show me the 
direction I should be taking!

Kind Regards,
