Code to make NPC wait from point a to point b

Questions & Answers

Ok so im a 3d artist and i im trying to make IA for NPC to walk around…i have basic code from unity documentation and it is like this now :

// Patrol.cs
using UnityEngine;
using UnityEngine.AI;
using System.Collections;

public class Patrol : MonoBehaviour {
	

    public Transform[] points;
    private int destPoint = 0;
    private NavMeshAgent agent;

    void Start () {
        agent = GetComponent<NavMeshAgent>();

        // Disabling auto-braking allows for continuous movement
        // between points (ie, the agent doesn't slow down as it
        // approaches a destination point).
        agent.autoBraking = false;

        GotoNextPoint();
    }

    void GotoNextPoint() {
        // Returns if no points have been set up
        if (points.Length == 0)
            return;

        // Set the agent to go to the currently selected destination.
        agent.destination = points[destPoint].position;

        // Choose the next point in the array as the destination,
        // cycling to the start if necessary.
        destPoint = (destPoint + 1) % points.Length;
    }
	

	 

    void Update () {
        // Choose the next destination point when the agent gets
        // close to the current one.
        if (!agent.pathPending && agent.remainingDistance < 0.5f)
            GotoNextPoint();
    }
}

now i know from the documentation that this code(is to wait) :

using UnityEngine;
using System.Collections;

public class WaitForSecondsExample : MonoBehaviour
{
void Start()
{
StartCoroutine(Example());
}

IEnumerator Example()
{
    print(Time.time);
    yield return new WaitForSecondsRealtime(5);
    print(Time.time);
}

}

my question is where to i add to the one above as just one script and make it work???can any one help me ? thanks a lot in advance

Supposing you want your agent to wait when he has reached a point:

public class Patrol : MonoBehaviour
{         
     public Transform[] points;
     private int destPoint = 0;
     private NavMeshAgent agent;
     private bool waiting;
     private WaitForSecondsRealtime wait;
     
     void Start ()
     {
         agent = GetComponent<NavMeshAgent>();
         // Disabling auto-braking allows for continuous movement
         // between points (ie, the agent doesn't slow down as it
         // approaches a destination point).
         agent.autoBraking = false;
         wait = new WaitForSecondsRealtime(5); 
         StartCoroutine( GotoNextPoint() );
     }
     
     IEnumerator GotoNextPoint()
     {
         // Returns if no points have been set up
         if (points.Length == 0)
             yield break;

         waiting = true ;
         
         yield return wait;
         
         waiting = false ;
         
         // Set the agent to go to the currently selected destination.
         agent.destination = points[destPoint].position;
         // Choose the next point in the array as the destination,
         // cycling to the start if necessary.
         destPoint = (destPoint + 1) % points.Length;
     }
     
      
     void Update ()
     {
         // Choose the next destination point when the agent gets
         // close to the current one.
         if (!agent.pathPending && agent.remainingDistance < 0.5f && !waiting)
             StartCoroutine( GotoNextPoint() );
     }
 }

Thanks for the replay… The code i have now is this :

// Patrol.cs
using UnityEngine;
using UnityEngine.AI;
using System.Collections;

public class Patrol : MonoBehaviour
{
public Transform points;
private int destPoint = 0;
private NavMeshAgent agent;
private bool waiting;
private WaitForSecondsRealtime wait = new WaitForSecondsRealtime(5);

  void Start ()
  {
      agent = GetComponent<NavMeshAgent>();
      // Disabling auto-braking allows for continuous movement
      // between points (ie, the agent doesn't slow down as it
      // approaches a destination point).
      agent.autoBraking = false;
      StartCoroutine( GotoNextPoint() );
  }
  
  IEnumerator GotoNextPoint()
  {
      // Returns if no points have been set up
      if (points.Length == 0)
          return;
      waiting = true ;
      
      yield return waiting;
      
      waiting = false ;
      
      // Set the agent to go to the currently selected destination.
      agent.destination = points[destPoint].position;
      // Choose the next point in the array as the destination,
      // cycling to the start if necessary.
      destPoint = (destPoint + 1) % points.Length;
  }
  
   
  void Update ()
  {
      // Choose the next destination point when the agent gets
      // close to the current one.
      if (!agent.pathPending && agent.remainingDistance < 0.5f && !waiting)
          GotoNextPoint();
  }

}

What i want is for my npc to go to point A,then B etc …but i want him to wait for a couple of seconds and then move to point B…etc…the code above is the one that is not working…The one that works is :

public class Patrol : MonoBehaviour {

 public Transform[] points;
 private int destPoint = 0;
 private NavMeshAgent agent;
 void Start () {
     agent = GetComponent<NavMeshAgent>();
     // Disabling auto-braking allows for continuous movement
     // between points (ie, the agent doesn't slow down as it
     // approaches a destination point).
     agent.autoBraking = false;
     GotoNextPoint();
 }
 void GotoNextPoint() {
     // Returns if no points have been set up
     if (points.Length == 0)
         return;
     // Set the agent to go to the currently selected destination.
     agent.destination = points[destPoint].position;
     // Choose the next point in the array as the destination,
     // cycling to the start if necessary.
     destPoint = (destPoint + 1) % points.Length;
 }
 
  
 void Update () {
     // Choose the next destination point when the agent gets
     // close to the current one.
     if (!agent.pathPending && agent.remainingDistance < 0.5f)
         GotoNextPoint();
 }

}

but that one the npc does not stop…just keeps moving from poitn a to b and to c etc…( this code above is the one from Unity - Manual: Making an Agent Patrol Between a Set of Points

and i want to add the waiting part of it as well…hope you understand what i said…thanks a lot again
