看敌方半径统一3D

Question

In my code I am trying to establish and a look radius on how far the AI enemy can see the player. When I run the code It comes up with "gizmo drawing functions can only be used in ondrawgizmos and ondrawgizmosselected". I don't know what this means or what I should do. Please help, thank you.

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

public class EnemyFollow : MonoBehaviour
{

    public float lookRadius = 10;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        Gizmos.color = Color.red;
        Gizmos.DrawWireSphere(transform.position, lookRadius);
    }
}

My C# code

I think you should do kinda next thing:

public float lookRadius = 10;

void OnDrawGizmos(){
    Gizmos.DrawSphere(transform.position, lookRadius);
}
