Question by D-Coy · May 15, 2017 at 11:23 PM · arrayvector3listrandom.range

Getting Vector3 from random item in List

Hi, New to C# and be stuck on this for a couple of nights. Trying to find a way to get transform info from a item randomly selected from an List. Had originally tried using an Array, but had read that using Lists were better suited.

Ultimately I want to be able to attach this script to a cube and have it Lerp quickly it between moving targets in my scene. Any help would be appreciated.

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

public class focusChaser3 : MonoBehaviour { public List targets = new List();

 void Start()
 {
     foreach (GameObject item in GameObject.FindGameObjectsWithTag("targetEye"))
     {
         targets.Add(item);
     }

     var targRan = Random.Range(0, targets.Count);
     Debug.Log(targets[targRan]);
     transform.position = new Vector3(targets[targRan].transform);
 }

}

Always format pasted code with the 101010 button.

You seem to have a handle on how to grab your random element, but you don't appear to be making use of it correctly. Perhaps you wanted:

 transform.position = targets[targRan].transform.position;
