How to run a method from another class in Ruby

Question

Hi I try to make my first game in ruby :)

I have two files:

#"game.rb" with code: class Game attr_accessor :imie, :klasa, :honor def initialize(start_scena) @start = start_scena end def name() puts "Some text" exit(0) end end

and second file

#"game_engine.rb" require_relative 'game.rb' class Start def initialize @game = Game.new(:name) end def play() next_scena = @start while true puts "\n---------" scena = method(next_scena) next_scena = scena.call() end end end go = Start.new() go.play()

The question is, how can I call class Game.name method from Start.play() class. The game goes deeper, and insted of 'exit(0)' it returns :symbol of another method from "Game" class that should work.

initialize method in Start class, @game is instance of Game class, but question is what is :name there?? — Alok Anand

:name refers to method called "name" in Game calss, or it should be pointing. Im very gen at this. — Kask

Make start readable for the Game class. DO NOT call exit(0) in your code unless it's really necessary. Instead, use some conditions to make sure the program runs to the end of script.

#"game.rb" with code: class Game attr_accessor :imie, :klasa, :honor attr_reader :start def initialize(start_scena) @start = start_scena end def name() puts "Some text" :round2 end def round2 puts "round2" nil end end

Use instance#method(...) to get a bounded method to that instance.

#"game_engine.rb" require_relative 'game.rb' class Start def initialize @game = Game.new(:name) end def play() next_scene = @game.start while next_scene puts "\n---------" scene = @game.method(next_scene) next_scene = scene.call() end end end go = Start.new() go.play()
