Question

我对使用groovy编程语言非常陌生，我正在尝试开发一种简单的Pelmanism游戏（Pairs）。游戏的目的是匹配4x4板上的字符对。

我已经填充了字符和弹出的对话框，询问行和列号，但是当我输入字符时，我不断收到消息说抱歉 - 你错了，即使我输入了正确的位置人物。

如果有人能就我做错了什么提供任何指导，我将不胜感激？我认为这与我编写代码比较两个字符的方式有关吗？

我已经复制了我到目前为止编写的源代码。正如我所说，我对此非常新，所以如果这听起来很简单就道歉。

import javax.swing.*
def int ask(message) {
  def txt = JOptionPane.showInputDialog(message)
  def temp = Integer.parseInt(txt)
  boolean valid=false
   while(!valid){
        if (temp<1||temp>4){
            txt = JOptionPane.showInputDialog("Number must be in the range 1 to 4")
            temp = Integer.parseInt(txt)
        } else {
            valid=true
        }
    }
    return temp
  return answer
}
def askReply (message) {
    def txt = JOptionPane.showInputDialog(message)
    boolean valid=false
    while(!valid){
        if (txt=="N" || txt=="n"|| txt=="Y"||txt=="y"){
            valid=true
        } else {
            txt = JOptionPane.showInputDialog("Enter Y or N only")
        }
    return txt
    }
}

主要问题是最后的比较部分，因为您实际上并没有比较指定位置的字符。比较逻辑基本上应该是：

def firstChar = Guess[row1 - 1][column1 - 1]
def secondChar = Guess[row2 - 1][column2 - 1]

if (firstChar == secondChar) {
    println "You got it!"
}
else {
    println "Nope."
}

字符的位置是错误的
