Question

我正在研究一个使用正方形的简单世界生成器。但它在随机数行后失败，它没有实例化最后一项。

我无法理解为什么它失败了，因为它有可用的块选项放在那个位置。在相同数量的行之后，它并不总是失败。

它有时也会将错误的块放在某些地方，但我认为这是由于另一个问题错误：

ArgumentOutOfRangeException: Argument is out of range. Parameter name: index 
System.Collections.Generic.List`1[UnityEngine.GameObject].get_Item (Int32 index
(at/Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Collections.Generic/List.cs:633) GenGround.Start () (at Assets/Code/GenGround.cs:93)

 // Update is called once per frame
 void Update() {

 }
}

错误在行结束时在while循环中实例化Prefab，在随机数量的行
