C# 如何使用循环最小化代码，并且不应重复随机数？

我有18个游戏对象，我想把所有18个游戏对象放在定义的随机位置。是的，我说的“定义位置”是指我的游戏对象z位置只会随机变化，比如[0,60,120,180等等]。请帮忙

GameObject[] hurdles;
int randShared;

void Shart()
    {
        hurdles = GameObject.FindGameObjectsWithTag("Hurdles");
        randShared = Random.Range(0,19);

        if (randShared == 0)
        {
            hurdles[0].transform.position = new Vector3(0f, 0f, 0f);
            hurdles[1].transform.position = new Vector3(0f, 0f, 60f);
            hurdles[2].transform.position = new Vector3(0f, 0f, 120f);
            .
            .
            .
            hurdles[18].transform.position = new Vector3(0f, 0f, 120f);
        }

        if (randShared == 1)
        {
            hurdles[0].transform.position = new Vector3(0f, 0f, 120f);
            hurdles[1].transform.position = new Vector3(0f, 0f, 0f);
            hurdles[2].transform.position = new Vector3(0f, 0f, 60f);
            .
            .
            .
            hurdles[18].transform.position = new Vector3(0f, 0f, 120f);
        }

        if (randShared == 2)
        {
            hurdles[0].transform.position = new Vector3(0f, 0f, 60f);
            hurdles[1].transform.position = new Vector3(0f, 0f, 120f);
            hurdles[2].transform.position = new Vector3(0f, 0f, 0f);
            .
            .
            .
            hurdles[18].transform.position = new Vector3(0f, 0f, 120f);
        }

        .
        .
        .

        if (randShared == 18)
        {
            hurdles[0].transform.position = new Vector3(0f, 0f, 60f);
            hurdles[1].transform.position = new Vector3(0f, 0f, 120f);
            hurdles[2].transform.position = new Vector3(0f, 0f, 0f);
            .
            .
            .
            hurdles[18].transform.position = new Vector3(0f, 0f, 120f);
        }
    }

您可以在您的范围内循环，并根据您的随机数以60为间隔创建偏移

for (var i = 0; i < 19; i++)
{
    var offset = i + randShared;
    if (offset > 18)
    {
        offset = offset - 19;
    }

    hurdles[i].transform.position = new Vector3(0f, 0f, (float)(offset * 60));

}

for（变量i=0；i<19；i++）
{
var offset=i+randShared；
如果（偏移量>18）
{
偏移量=偏移量-19；
}
跨栏[i].transform.position=新矢量3（0f，0f，（float）（偏移量*60））；
}

var rnd=new Random（）；
对于（变量i=0；i<19；i++）
跨栏[i].transform.position=new Vector3（0f，0f，60f*rnd.Next（4））；

它可以工作，但不是随机的，此代码按顺序生成zPos。根据randShared，只有第一个是随机的。我想要随机的zPos@Zdravko DanevIts显示错误，类型为

UnityEngine.Random'不包含

Next'的定义，并且找不到类型为UnityEngine.Random'的扩展方法

Next'。是否缺少程序集引用@Zdravko Danev将其更改为System.RandomOk，现在错误消失。但所有的障碍都出现在接下来的4个位置，其余14个位置都是空的：(
var rnd = new Random();
for (var i = 0; i < 19; i++)
    hurdles[i].transform.position = new Vector3(0f, 0f, 60f * rnd.Next(4)));
