Subject: Re: How can I overwrite class variables

Wow! I knew someone would come with a better solution. Awesome!

I'm not trying to improve your code I'm just trying to practice by
overwriting variables (in this case an instance variable not a class
variable).
----------------------------------------
class Machine
  def initialize(part_width, part_length)
    @part_width = part_width
    @part_length = part_length
  end

  def laser
    @kerf = 20
    calc
  end

  def turret
    @kerf = 10
   calc
  end

  private

  def calc
    sheet_width = 60
    sheet_length = 120

    parts_y = sheet_width / (@part_width + @kerf)
    parts_x = sheet_length / (@part_length + @kerf)
     puts parts_y * parts_x
  end
end

machine1 = Machine.new(10 , 20)
machine1.laser
machine1.turret
----------------------------------------------------
This makes me feel good and bad, good because its increible to see
people helping others and whats best see people that identify the
problem in a metter of seconds (you guys are awesome) and bad becuase I
could't figure this out by my self :(

Thanks a lot
