直接上代碼：

#encoding:utf-8class Dungeon  #建立Get Set方法  #儲存玩家和room列表  attr_accessor :player  def initialize(player_name)    @player = Player.new(player_name)    @room = []  end  #設定玩家location屬性  def start(location)    @player.location = location    show_current_description  end  #根據玩家location找到所在房間  def show_current_description    puts find_room_in_dungeon(@player.location).full_description  end  #  def find_room_in_dungeon(reference)    @room.detect{|room|room.reference == reference}  end  #  def find_room_in_direction(direction)    find_room_in_dungeon(@player.location).connections[direction]  end  #  def go(direction)    puts "去 #{direction.to_s}"    @player.location = find_room_in_direction(direction)    show_current_description  end    #添加房間  def add_room(reference, name, description, connections)    @room << Room.new(reference, name, description, connections)  end    #Player = Struct.new(:name, :location)  #Room = Struct.new(:reference, :name, :description, :connections)endclass Player  #建立Get Set方法  #儲存名字和當前位置  attr_accessor :name,:location  def initialize(player_name)    @name = player_name  endendclass Room  #建立Get Set方法  #儲存名字，說明，與其它房間的串連方式，供其它房間串連的引用  attr_accessor :reference,:name,:description,:connections  def initialize(reference, name, description, connections)    @reference = reference    @name = name    @description = description    @connections = connections  end    def full_description    "#{@name}\n \n在 #{@description}"  endend#Mainmy_dungeon = Dungeon.new("larry")#Add roomsmy_dungeon.add_room(:largecave, "大洞穴", "大的,空蕩蕩的洞穴", {:west => :smallcave})my_dungeon.add_room(:smallcave, "小洞穴", "小的,密閉的洞穴", {:east => :largecave})#Startmy_dungeon.start(:largecave) my_dungeon.go(:west)my_dungeon.go(:east)
