I'm running through Ruby Warrior, and I'm at Level 6 (https://www.bloc.io/ruby-warrior/#/warriors/26290/levels/6). I've completed the level, but I need to clean up the code. I'm not sure exactly what the problem is. This code doesn't stop and rest in one spot until health == 20. It keeps walking around while resting. The code 'as is' is successf…

Ruby_Warrior_Level_6.rb

class Player
  
  def initialize
    @health = 20
    @wall   = 0
  end
  
  def play_turn(warrior)
    if @health >= warrior.health
      if    warrior.feel.enemy?              then warrior.attack!
      elsif warrior.health < 20              then warrior.rest!
      elsif warrior.feel(:backward).captive? then warrior.rescue!(:backward)
      elsif warrior.feel.captive?            then warrior.rescue!
      elsif warrior.feel(:backward).wall?    then warrior.walk!
        @wall = 1
      elsif @wall == 1                       then warrior.walk!
      else warrior.walk!(:backward)
      end
    else
      if    warrior.feel.enemy? && warrior.health > 6  then warrior.attack!
      elsif warrior.feel.empty? && warrior.health > 13 then warrior.walk!
      else  warrior.walk!(:backward)
      end
    end
    @health = warrior.health
  end
  
end

SOLVED: I was assuming incorrectly about when the game was adding/subtracting health from the warrior. Once I realized that, I figured it out.
