为猜谜游戏保存分数

Question

下面是我的代码。一切都很好，但我不知道如何保持对随机数的最低猜测量的得分。我如何跟踪高分(高分是猜测系统给出的随机数所需的最低猜测次数)。我是一个初级程序员，这是我第一次制作gui，所以我为混乱道歉。

Answer 1

你看这里有:saveScore = clicked;?把那行代码放在这里可不是个好地方。如果你设置saveScore等于clicked然后在下一行代码中检查clicked是否小于或等于(<=)saveScore，考虑到在前一行代码中您使saveScore等于clicked，您认为会发生什么?

将saveScore = clicked;作为if语句代码块的第一行代码移动到它的正下方。使saveScore只在之后等于clicked你知道clicked确实比saveScrore小。
