How do you set up navmesh agents to go to multiple destinations?

[Polinator]

I looked at some tutorials and the documentation on how NavMeshAgents work, and currently have NPC’s going to a target in my scene. I can’t seem to find where the documentation tells me how to setup multiple destinations for my NPC though. Here is my code for the NavMesh with one target:

public var target : Transform;

function Start () {
	GetComponent(NavMeshAgent).destination = target.position;
}

Now here is what I thought up in order to do multiple positions:

public var currentTarget : Transform;
public var targets : Transform[];
public var navigation : NavMeshAgent;
public var i : int = 0;


function Start () {
	
	navigation.destination = targets*.position;*

}

function Update () {
_ var dist = Vector3.Distance(targets*.position,transform.position);_
_ currentTarget = targets;*_

* //if npc reaches its destination…*
* if (dist < 5){*
* //go to next target by setting it as the new destination*
* navigation.destination = navigation.nextPosition;*
* if (i < targets.Length){*
* //change next target*
* i++;*
_ navigation.nextPosition = targets*.position;
}
}*_

}
At the moment the NPC is warping all the way down to the last transform in targets[], so I think it’s because “i” is getting incremented too fast? How should I fix this?

I figured it out a fix for myself, but it doesn’t use nextPosition, so if anyone would like to chime in and explain how I would exactly use that, it’d be great.

Here’s my fix, everything works fine:

public var currentTarget : Transform;
public var targets : Transform[];
public var navigation : NavMeshAgent;

private var i : int = 0;


function Start () {
	
	navigation.destination = targets*.position;*

}

function Update () {
_ var dist = Vector3.Distance(targets*.position,transform.position);_
_ currentTarget = targets;*_

* //if npc reaches its destination (or gets close)…*
* if (dist < 5){ *
* if (i < targets.Length - 1){ //negate targets[0], since it’s already set in destination.*
* i++; //change next target*
_ navigation.destination = targets*.position; //go to next target by setting it as the new destination*
* }
}*_

}

Link to the docs… (I imagine that these docs are newer than the question).

Hi, to cycle between destinations:

#pragma strict


private var targets : GameObject[];
private var navigation : NavMeshAgent;
private var i : int = 0;
     
     
function Start () 
  	{
        navigation = GetComponent(NavMeshAgent);
     	targets = GameObject.FindGameObjectsWithTag("NavTarget");
        
     	//set first target
        navigation.destination = targets*.transform.position;* 

• }*

function Update ()

• {*
  var dist = Vector3.Distance(targets*.transform.position,transform.position);*
  //currentTarget = targets*.transform;*
  //if npc reaches its destination (or gets close)…
  if (dist < 2)
  *{ *
  i++; //change next target
  if (i < targets.Length )
  * {*
  navigation.destination = targets*.transform.position; //go to next target by setting it as the new destination*
  * }*

//check if at end of cycle, then reset to beginning of cycle
if (i == targets.Length )
* {*
* Debug.Log(“NAVIGATION FINISHED. RESET.”);*
* i = 0;*
_ navigation.destination = targets*.transform.position;
}
}
}*_
