Subject: Stumped newbie...

Here is what I'm trying to do. Simulate nodes with objects. The nodes 

are updated with the class's update method, now where I'm stuck is 

acessing outside variables within the method.

Simply, how do I refer to an objects state within a method?

class Gate
  def initialize
    @state = rand(2)
  end
  def state
    @state
  end
  def update
    @state = a[1].state
  end
end

num = 2

a = Array.new
for b in 0..(num - 1)
  a[b] = Gate.new
  puts a[b].state
end

puts
puts a[0].state
a[0].update
puts a[0].state


Can anyone tell me how to do this?
