Question

我开始为我的学习红宝石做一个小游戏，练习第43号，在我做任何课程之前，我尝试过这样做：

def start
  puts '''Times are tough and we need your help as much as ever.
Plase tell me, what do you do for living? Are you maybe a:
a. swift and strong skater
b. wise and clever lawyer during his first year at University
c. dreamer who only read one book but a good book and a communist commerade in one person'''

  print "> "  
  class = $stdin.gets.chomp.downcase
  if class == "a" || "skater" || "swift and strong skater"

strenght = 5 + Random.rand(12)
dexterity = Random.rand(9...17)
inteligence = Random.rand(7..14)
charisma = 2 + Random.rand(10)

  puts '''Your stats are:
          STRENGHT: #{strenght}
          DEXTERITY #{dexterity}
          INTELIGENCE #{inteligence}
          CHARISMA #{charisma}
          Good job! '''
          armory_room
  end
end

它没有用，我得到了：“未初始化的恒定”按摩。我也试过这个：

charisma = 2 + Random.rand(10)
puts "Pls work #{charisma}"

我再次得到了“未初始化的”按摩。为什么它不起作用，我应该如何使它工作？

Answer 1

class是保留名称。您不能将其用作变量名称。请尝试使用class_。

Answer 2

在ruby中，class是保留关键字。最佳做法是使用

克拉斯

生成随机数时，未初始化为常量
