unity随机更换相互子物体位置

可以使用以下代码实现：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RandomizeChildPositions : MonoBehaviour
{
    void Start()
    {
        int childCount = transform.childCount;
        List<Transform> children = new List<Transform>();
        for (int i = 0; i < childCount; i++)
        {
            children.Add(transform.GetChild(i));
        }

        Shuffle(children);

        for (int i = 0; i < childCount; i++)
        {
            children[i].SetSiblingIndex(i);
        }
    }

    void Shuffle(List<Transform> list)
    {
        int n = list.Count;
        while (n > 1)
        {
            n--;
            int k = Random.Range(0, n + 1);
            Transform value = list[k];
            list[k] = list[n];
            list[n] = value;
        }
    }
}

这段代码会将父物体下的所有子物体随机排序，从而实现随机更换相互子物体位置。
