Question

有人知道为什么这会给游戏对象数组的索引带来错误吗？

public GameObject[] Prefab;
public GameObject[] CopyPrefab;

for (int i = 0; i < 10; i++)
{
    CopyPrefab[i] = Instantiate(Prefab[i]) as GameObject;
}

错误：IndexOutOfRangeExCeption: Index was outside the bounds of the array.

我尝试了CopyPrefab[i-1] = Instantiate(Prefab[i-1]) as GameObject;和CopyPrefab[i] = Instantiate(Prefab[0]) as GameObject;。我不明白我在做什么错

Answer 1

您如何知道GameObject []中对象的确切数量？不要将循环结束条件硬编码为i <10。相反，您应该使用foreach循环进行循环或使用Array的Length属性。

Looping in C#

Answer 2

public GameObject[] Prefab;
public GameObject[] CopyPrefab;
CopyPrefab = new GameObject[Prefab.Length];
for (int i = 0; i < Prefab.Length; i++)
{
    CopyPrefab[i] = Instantiate(Prefab[i]) as GameObject;
}

首先，确保两个数组长度相同，如果CopyPrefab.Length = 10，您只能使用CopyPrefab [0 ... 9]，不能使用CopyPrefab [-1]或CopyPrefab [10] ...“超出范围”

GameObject数组初始化的“索引超出数组范围”
