Question: Modify the scream method to increment the screams key of the @actions hash before printing out that the monster screams.

Code:

monster.rb 
class Monster
  attr_reader :name, :actions

  def initialize(name)
    @name = name
    @actions = {
      screams: 0,
      scares: 0,
      runs: 0,
      hides: 0
    }
  end

  def scream(&block)

    print "#{name} screams! "
    @actions[screams] = @actions[screams] + 1
  end

end

monster = Monster.new("Fluffy")

monster.scream { puts "BOO!" }

Hi, Devin Scheu

  • increment the :screams key before print statement, not after.
  • also, your Hash key lookup isn't correct, you need to use the symbol as key.
  def scream(&block)
    @actions[:screams] += 1
    print "#{name} screams! "

  end
