I'm sorry if this question seem stupid, but couldn't find it in the books.

I have this code in the models directory:
class Figure
  attr_reader  :xpos, :ypos

  def initialize
    @xpos = 0
    @ypos = 0
    @other = 0
    @another = 0
  end

  def some
     call_other(@xpos,@ypos)
  end

  def more
     call_other(@other,@another)
  end

  def call_other(var1, var2)
    max = 9
    var1= rand(max)
    var2=rand(max)
  end
end


And have this on my controller:

  def figure
    fig = Figure.new
    fig.some
    render :text => "<h1>new values</h1>"+fig.xpos.to_s+" "+fig.ypos.to_s
  end

Problem is, it always print 0 0... as if the random wouldn't work, but I
have test the random outside this method (calling it in the first method,
not the second one), but the second method is one I need cos I use it too
many times and with different instance variables

Any help?
