Question

我需要在Unity中生成一个游戏对象，它会生成数字。

对某些人来说，原因是预制件产生的数字早于预期。例如：预制件显示＆＃34; 10＆＃34;，但实际变量实际上是24。＆＃34; 10＆＃34;预制件被毁坏，另一个产生了＆＃34; 24＆＃34;。所以基本上，预制件正在被推迟＃。

你有这个：

   switch (HexToBinary.rand1)
   {
       case 1:
           valGroup1 = "1";
           break;

稍后在一些评论代码中：

HexToBinary.HexBin[rand1].ToString()

你遇到的问题是数组（至少在很多语言中，包括C＃）start at index 0。

此处的索引1（通过switch语句将valGroup1设置为字符串"1"）实际上是2的值：

   HexBin.Add(1); // <-- index 0
   HexBin.Add(2); // <-- index 1

当然......无论如何，你都错过了零价值......这样也可以解决你的问题。

作为旁注，您根本不需要switch语句（更不用说两次，您可以将其封装为函数！），您只需使用ToString("X")即可。

我还看到一些变量被视为静态而一些变量没有（甚至静态变量都被HexToBinary.var和var混合引用），没有明确的原因。如果您需要从场景there are other ways中其他位置附加的其他脚本访问这些值。
