Build a Monster Class: Part 3

Code Samples

Here is our final Monster class:

class Monster
  attr_reader :name, :actions

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

  def say(&block)
    print "#{name} says... "
    yield
  end

  def print_scoreboard
    puts "------------------------------"
    puts "#{name} scoreboard"
    puts "------------------------------"
    puts "- Screams: #{actions[:screams]}"
    puts "- Scares: #{actions[:scares]}"
    puts "- Runs: #{actions[:runs]}"
    puts "- Hides: #{actions[:hides]}"
    puts "------------------------------"
  end

  def scream(&block)
    actions[:screams] += 1
    print "#{name} screams! "
    yield
  end

  def scare(&block)
    actions[:scares] += 1
    print "#{name} scares you! "
    yield
  end

  def run(&block)
    actions[:runs] += 1
    print "#{name} runs! "
    yield
  end

  def hide(&block)
    actions[:hides] += 1
    print "#{name} hides! "
    yield
  end
end

And here is how we can use it:

monster = Monster.new("Fluffy")
monster.say { puts "Welcome to my home." }

monster.scream do
  puts "BOO!"
end

monster.scare do
  puts "Go away!"
end

monster.run do
  puts "Going to get you!"
end

monster.hide do
  puts "Running away and hiding!"
end

puts "\n"
monster.print_scoreboard
