detect enemy when seen

so i have this script for random movement of ai

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class WanderingAI : MonoBehaviour
5. {
6.  
7.     public float wanderRadius;
8.     public float wanderTimer;
9.  
10.     private Transform target;
11.     private UnityEngine.AI.NavMeshAgent agent;
12.     private float timer;
13.  
14.     // Use this for initialization
15.     void OnEnable()
16.     {
17.         agent = GetComponent<UnityEngine.AI.NavMeshAgent>();
18.         timer = wanderTimer;
19.     }
20.  
21.     // Update is called once per frame
22.     void Update()
23.     {
24.         timer += Time.deltaTime;
25.  
26.         if (timer >= wanderTimer)
27.         {
28.             Vector3 newPos = RandomNavSphere(transform.position, wanderRadius, -1);
29.             agent.SetDestination(newPos);
30.             timer = 0;
31.         }
32.     }
33.  
34.     public static Vector3 RandomNavSphere(Vector3 origin, float dist, int layermask)
35.     {
36.         Vector3 randDirection = Random.insideUnitSphere * dist;
37.  
38.         randDirection += origin;
39.  
40.         UnityEngine.AI.NavMeshHit navHit;
41.  
42.         UnityEngine.AI.NavMesh.SamplePosition(randDirection, out navHit, dist, layermask);
43.  
44.         return navHit.position;
45.     }
46. }

and i was wondering if i could add a player detection to it so if i get within a trigger or somthing it detects the player and goes in that direction

 

Yep, add a trigger collider of the appropriate size and shape on a child object of the enemy and add an OnTriggerEnter to your script.

 

ight thx but is there a way to disable the random movement script while inside the trigger

 

Sure make a boolean variable that you set to true when the enemy sees the player. Use that variable to decide which movement behavior to run with an if statement.

 

ight thx
