Question

所以我用红宝石写这个游戏，我有这个功能：

puts "Monsters that make you loose a hand-weapon"
  for m in monsters
    specificTreasures = Array.new
    specificTreasures = m.bc.SpecificVisibleTreasures + m.bc.specificHiddenTreasures
    for treasure in specificTreasures
      if (treasure == TreasureKind::ONEHAND)
        puts m.to_s
        break
      end
    end
  end

bc是“badconsequence”，bc指向一个“怪物”类，它有：

def initialize(name, level, prize, bc)
    @name = name
    #@combatLevel = level
    @level=level
    @prize = prize
    @badConsequence = bc
  end

和类badconsequence：

def initialize(aText, someLevels, someVisibleTreasures, someHiddenTreasures, someSpecificVisibleTreasures, someSpecificHiddenTreasures, death)
    @text = aText
    @levels = someLevels
    @nVisibleTreasures = someVisibleTreasures
    @nHiddenTreasures = someHiddenTreasures
    @SpecificVisibleTreasures = someSpecificVisibleTreasures
    @SpecificHiddenTreasures = someSpecificHiddenTreasures
    @death = death
  end

但它给了我这个错误： NoMethodError：nil的未定义方法`SpecificVisibleTreasures'：NilClass

请帮忙吗？

好的，谢谢大家，我已经修好了。它是其中一个类中的attr_accessor，我使用不同的循环类型更改了主要内容：

monsters.each do |monstruo|

...

所以，就是这样，它现在有效。
