class Player

  def play_turn(warrior)
    # cool code goes here
    @warrior = warrior
    @previous_health ||= @warrior.health

    forward_spaces = @warrior.look
    backward_spaces = @warrior.look(:backward)

    enemy_ahead = forward_spaces.any?(&:enemy?)
    enemy_behind = backward_spaces.any?(&:enemy?)
    captive_ahead = forward_spaces.any?(&:captive?)
    stairs_ahead = forward_spaces.any?(&:stairs?)

    if !enemy_ahead && !enemy_behind && @warrior.health < 20
      @warrior.rest!
    elsif @previous_health > @warrior.health
      # Taking damage so head towards nearest enemy
      if @warrior.feel.enemy?
        @warrior.attack!
      else
        @warrior.walk!
      end
    elsif enemy_ahead && !captive_ahead
      @warrior.shoot!
    elsif forward_spaces[0].captive?
      @warrior.rescue!
    elsif forward_spaces.any?(&:wall?) && !stairs_ahead && !captive_ahead
      @warrior.pivot!
    else
      @warrior.walk!
    end

    @previous_health = @warrior.health
  end
