using UnityEngine;using UnityEngine.AI;public class Target : MonoBehaviour{    private NavMeshAgent[] navAgents;    public Transform targetMarker;    private void Start ()    {      navAgents = FindObjectsOfType(typeof(NavMeshAgent)) as NavMeshAgent[];    }    private void UpdateTargets ( Vector3 targetPosition )    {
