Hey guys, So Im trying to build a simple game in rails. Its premise is to add all the numbers up in your memory and type in the highest sum you can within a predefined time limit. Right now I able to generate the numbers and check for correct answers, however I don`t know how to loop the method in a way that points are added after each successful round.

I`m assuming the problem is that for each instance of "new" it sets the start_game开发者_如何学C method again, thus zeroing the points and round again?

You are correct, every time you hit the 'new' action it will start your game over again. You could do something like below to get it to keep over multiple requests to 'new'

  def start_game
    session[:round] ||= 1
    session[:points] ||= 0
    @round = session[:round]
    @points = session[:points] 
  end

  def game_over
    session[:round] = nil
    session[:points] = nil
    puts "Game Over."
  end
