I Must Be Missing Something Simple

[Tomo2000 60]

Meddling with C++ and Java lately for university has really been screwing with my general ability to RGSS, but I digress. This is nowhere near the final version but I simply want a script where, in a script section of an event, I can initialize it and then do something like "if @citizens.isInfected == true". I'm sure I must be doing something simple wrong but I have no idea why. Thanks guys.

class Citizens
  attr_accessor   :infected
 
  def initialize
    @citizen_id = 0
    @infected = false
  end
 
  def isInfected
    if @infected == true
      return true
    else
      return false
    end
  end

  def getInfected
    @infected = true
  end
end
