Ignoring Tone

[khmp]

In the hidden sprite class is a method for manipulating tone. I need to alias the manipulation of this property if possible.

class Sprite
  attr_accessor :ignore_tone
  alias_method :test_sprite_tone=, :tone=
  def tone=(tone)
    p 'here'
    return if ignore_tone
    self.test_sprite_tone=(tone)
  end
end

It never reaches that print. So I assume I'm screwing up somewhere or aliasing the wrong method. I would be eternally grateful to someone who might be able to offer a solution or guidance to this dilemma.

Thanks for taking the time to read this. :thumb:

You're absolutely right. I omitted an important detail I guess. The problem lies in the fact that I'm doing this through a Viewport object. In XP the above code works as well. :lol: Here's what I'm trying to get done. When the Viewport's tone is changed I want some of the sprites within the viewport to be ignored. I figured the Viewport was setting each of the Sprite's tones when the Viewport's tone was changed. Looks like I'm wrong.

viewport = Viewport.new(0, 0, 640, 480)
sprite1 = Sprite.new(viewport)
sprite2 = Sprite.new(viewport)
viewport.tone = Tone.new(0, 0, 0, 0)

...normally hidden classes can only only be acces like so:
class << Input
class << Graphics

blabla... im not sure if that will help... although most hidden "classes" are actually modules (input and graphics are)
