In this stage, we'll be working towards creating our own class that uses blocks, arrays, hashes, and more. In this video, we'll print out a scoreboard of our monster's actions.
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
