在尝试提供更具信息性的标题10分钟之后，我的想法用完了。
我有2个问题。首先，每当我尝试输入pos_in的位置时，它会在nul语句中运行时注册为case，该语句确定该转弯的m_index。
第二，每当AI转弯时，总是选择1 1。
我的问题是：有什么方法可以解决这个问题吗？我试过切换输入类型无济于事，我完全不知道该做什么。
我的代码：
$moves = ["x", "o"]
$move = 1
m_index = 0
$spots = [" ", " ", " ", " ", " ", " ", " ", " ", " "]
possiblesx = (1..3)
possiblesy = (1..3)

您指定
pos_in = "1 1"
作为String，在你的case语句中检查数组
case pos_in
when ["1 1"]
答案 1 :(得分：1)
你遇到的问题是你的范围，以及你试图将字符串与数组匹配的事实，正如Piotr Kruczek指出的那样。
将pos_in变量设为全局变量，并将数组输入中的when语句更改为字符串。
以下是您的代码的工作版本：
$moves = ["x", "o"]
$move = 1
m_index = 0
$spots = [" ", " ", " ", " ", " ", " ", " ", " ", " "]
$pos_in = nil

正如Piotr和Menelik所说，这里有一些明显的错误。奇怪的是，ai_move的结构就是其中之一。工作代码如下。这不是最干净的东西，并且有一些错误需要解决，但它确实有效。
$moves = ["x", "o"]
$move = 1
m_index = 0
