我正在尝试制作一个游戏，当您点击与顶部数字匹配的数字时，数字网格会随机化。
我还没有鼠标输入的代码但是我如何随机化数字网格以便没有重复并且其中至少有一个与顶部数字匹配？
此外，我如何才能使数字仅在鼠标点击其中一个时才会改变，这样它们每1/60秒不会改变一次？

你需要一个 n 数字的数组，每当你初始化你的网格时，你从它中随机选择一个数字（使用System.Random）作为顶部数字，你从数组中删除它你也把它复制到网格中。您可以对网格的其他数字执行相同的操作，每次将其添加到网格中时删除一个数字，这将确保您不会有任何重复的数字。
对于另一个问题，如果你想让数字只在鼠标点击其中一个时改变，你只需要在检测到鼠标点击时更新你的结构，而不是每个周期都这样做。
