The Self Defense gem in action

The example below demonstrates how Bob the Martial Artist can defend himself 10 times in 30 seconds before adopting a different strategy.

require 'self-defense'

class MartialArtist
  
  def initialize()

  end

  def defend(manoeuvre={})
    action = ''
    strategy = lambda do |defense|

      coping_with_it = []
      coping_with_it << defense.sustained?(duration: '30s', hit_limit: 10)

      action = coping_with_it.all? ? 'blocked' : 'stop hitting me'
    end

    SelfDefense.new(&strategy) 
    puts Time.now.to_s + ': ' + action.to_s
  end
end


bob = MartialArtist.new

Time.now #=> 2013-08-16 18:42:43 +0100

bob.defend against: :kick  #=> 2013-08-16 18:42:43 +0100: blocked
