Assign 3 gameObjects to 3 random specified positions-CodePudding

I have 3 gameObjects created in my scene. And I have 3 Vector positions defined as well. I want to randomly assign each of these gameObjects to one of the positions. But no more than 1 gameObject should have same position as other. How do I use Random.Range() property here? Or is there a better approach?

public GameObject[] myObjs;
public Vector3[] myPos;

void Start(){
 var number = Random.Range (0, myPos.Length);
}

CodePudding user response：

Simply shuffle one of the arrays and then assign them in order like e.g.

using System.Linq;

...

public GameObject[] myObjs;
public Vector3[] myPos;

void Start()
{
    var randomPositions = myPos.OrderBy(n => Random.value).ToArray();

    var amount = Mathf.Min(myPos.Length, myObs.Length);

    for(var i = 0; i < amount; i  )
    {
        myObjs[i].transform.position = randomPositions[i];
    }
}

This simply uses Linq OrderBy to sort the items of myPos gien a certain order "property". Here we simply pass in Random.value. => randomPositions will contain all the item of myPos exactly once but in random order. So then you can just iterate and assign them in a normal loop.
