Problem with calculating distance

Questions & Answers
1

So I’m trying to make a script that checks that a tagged object is still near it after three seconds. If it’s still less than a certain distance away, the script will load the “completed” state for the level through a separate script called DataCenter.

For whatever reason, though, once I added the distance calculation it started giving me null reference errors. Here’s the code:

var bulletObject : GameObject;
var endStar : GameObject;

function Update ()
{

}

function OnTriggerEnter(hit : Collider)
{
	if(hit.tag == "Player")
	   {
	     yield WaitForSeconds (3);
		     var distance = Vector3.Distance(bulletObject.position, endStar.position);
				if (distance > 3.0f) {
				DataCenter.allDestroyed=true;
				}
			}
}

The error is on line 14

Anyone have any idea why this might be happening? I’m still new to the coding side of game development.

if bulletObject and endStar are gameobjects as stated at the top of your code, you need to use transform.

Line 14 should be

var distance = Vector3.Distance(bulletObject.transform.position, endStar.transform.position);

If thats not it, try Debug.Log on both of those objects on line 13 to make sure they are there.
