how to make an enemy move towards the player within a certain range using navmesh-CodePudding

I have been attempting to add a "range" of sorts to my enemy movement (too many move toward the player at once) and I have seen one solution but I am uncertain how to implement it as it doesn't really detect that I'm using the dis and distval values.

I am not trying to add any movement or route for them to follow. Just a wide (but not too wide) activation sphere of sorts. (also note that I am new, and I know it's probably a stupid question to ask, but I still don't know the answer to it and can't find it ((or at the very least understand it))).

here is my code.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;
public class Follow : MonoBehaviour
{
    public NavMeshAgent enemy;
    public Transform Player;
    

    // Update is called once per frame
    void Update()
    {
        var distVal = 5.0f;
        var dis = Vector3.Distance(enemy.position, Player.position);

        if (dis <= disVal)
        {
            enemy.SetDestination(Player.position);
        }
    }
}

If you set a NavMeshAgent's destination to be its own position it will stop moving.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;
public class Follow : MonoBehaviour
{
    public NavMeshAgent enemy;    
    public Transform Player;


    // Update is called once per frame
    void Update()
    {
        float distVal = 5.0f;
        float dist = Vector3.Distance(enemy.transform.position, Player.position);

        if (dist <= distVal)
        {
            enemy.SetDestination(Player.position);
        }
        else
        {
            enemy.SetDestination(enemy.transform.position);
        }
    }
}

This should do what you want. But I should point out you were never using your distVal variable, and that enemy.position should have been enemy.transform.position.
