将proc存储在哈希内的数组中 [英] Storing a proc inside an array inside a hash

问题描述

我仍在从事文字冒险.我在使用/使用功能时遇到麻烦.它的目的是调用一个哈希，其中的键是使用的对象，内容包括一个数组.数组中的第一个元素是目标对象，第二个元素是Proc，如果该关系变成与use/with函数的参数匹配，则将执行该Proc.

I am still working on my text adventure. I am having trouble with the use/with function. It is meant to call a Hash in which the key is the used object and the content includes an array; the first element in the array is the target object, and the second a Proc that will be executed if that relation turns to match the arguments for the use/with function.

请，您可以澄清一下如何将代码块存储在哈希内部的数组中，以便以后可以根据组合的对象来调用它吗?

Please, may you clarify me how I can store a code block inside an array inside a hash so I can recall it later depending on the objects that are being combined?

这是我的使用函数，它使用将对象与 with 一起使用":

Here is my use function that takes "use object with with":

    def use(object, with)
    if INTERACTIONS[object][0] == with
        INTERACTIONS[object][1]
    end
end

这就是我定义关系的方式(到目前为止只有一种):

And this is how I defined the relations (so far there is just one):

INTERACTIONS = {"key" => ["clock", p = Proc.new{puts "You open the clock!"}]}

每当我键入

use key with clock

它只返回新的提示行.

推荐答案

您忘记了 .call proc:

INTERACTIONS = {"key" => ["clock", Proc.new {puts "You open the clock!"}]}

def use(object, with)
  if INTERACTIONS[object][0] == with
    INTERACTIONS[object][1].call  # procs need to be `call`ed :)
  end
end


use("key", "clock") # => You open the clock!
