Ruby-如何从嵌套在哈希中的数组访问键

Question

I'm working on a small video game on the console where I have a main config hash that stores values for the game. When I try to access keys in an array in that hash, they don't return anything. Am I doing something wrong?

cfg =
{
    :gameVersion => 1.0,
    :invPouch => ['flint', 'string'],
    :gold => 50
}

puts cfg[:invPouch[1]]

Answer 1

It should be:

puts cfg[:invPouch][1]

In your case, :invPouch[1] is "n" , and cfg["n"] gives you nil .
