从阵列列表中产生一个数字，显示前面的数字
我需要在Unity中产生一个gameobject，在那里它会产生数字。从阵列列表中产生一个数字，显示前面的数字
对于某些人来说，预制产品的原因是早于应该产生的数字。例如：预制件显示“10”，但实际变量实际上是24.“10”预制件被破坏后，另一个预制件产生“24”。所以基本上，预制被“延迟”了。

回答：
你有这样的：
switch (HexToBinary.rand1){
case 1:
valGroup1 = "1";
break;
再后来在一些注释代码：
HexToBinary.HexBin[rand1].ToString()
你的问题是，数组（至少，大量o f语言，包括C＃）start at index 0。
指数1在这里（你设置valGroup1通过你的switch语句中的字符串"1"）实际上是2值：
HexBin.Add(1); // <-- index 0HexBin.Add(2); // <-- index 1
当然......你错过值无论如何......这样就可以解决你的问题了。作为一个方面说明，根本不需要switch语句（少两次，你可以将它封装为一个函数！），你可以使用ToString("X")来代替。这将真的让事情变得更容易！
我也看到一些变量被视为静态，有些没有（甚至静态的变量被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中其他位置的其他脚本访问这些值。
