Subject: Re: Ruby-warrior : Teaching AI concepts with Ruby

Hello guys! I consider RubyWarrior may be useful for learning. A have
reached for 6'th level (as beginner).

Now my code looks as following: http://good.net/_5pJ5Rurvz .
I can't understand issue: if i call in method:
    def roam_to_combat!
      debug("Entering roam_to_combat")
      state = :ws_combat
      @ini_health = health
      debug(@ini_health)
      warrior.attack!(cur_dir)
    end

then it lacks to execute string "state = :ws_combat".
But if i call
    def roam_to_combat!
      debug("Entering roam_to_combat")
      self.state = :ws_combat # <-- here is difference
      @ini_health = health
      debug(@ini_health)
      warrior.attack!(cur_dir)
    end
then it executes "state = :ws_combat" normally.

Why it didn't execute "state =" without "self"?
Is it Ruby's bug?
I got Ruby 1.8 installed.
