Follow Script attached Object Won't Follow Player

Unity Engine
1

All,

Below is a script that i found online. The idea is for a turret to follow the player by (looking at him). It worked fine after finessing it a bit. I realized that I had to ensure that the object that the “follow” script was attached to was on the same y axis as the player.

For some reason, after I rebuilt my player prefab, (My previous one was corrupted) The object will not follow the player. I tried to ensure that the Transform Y value was the same for my player’s ship and the turret object. I am not sure what if the issue is code related, or if I’ve done something wrong in the prefabs. Any suggestions would be greatly appreciated.

PS: I’m making a top down shooter.

var attackRange = 30.0;
var shootAngleDistance = 10.0;

var FireFreq : float ;
var enemyBullet : GameObject;
var enemyBullet2: GameObject;


private var lastShot : float;

var target : Transform;


function Start () {
    if (target == null  GameObject.FindWithTag("Player"))
        target = GameObject.FindWithTag("Player").transform;
}

function Update () {


if (Time.time > lastShot + FireFreq){


    Shoot();
}

    if (target == null)
        return;

    if (!CanSeeTarget ())
        return;

    // Rotate towards target   
    var targetPoint = target.position;
     //targetPoint.y = transform.position.y;
   
    var targetRotation = Quaternion.LookRotation (targetPoint -     transform.position, Vector3.up);
    transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, Time.deltaTime * 2.0);

// If we are almost rotated towards target - fire one clip of ammo
var forward = transform.TransformDirection(Vector3.forward);
var targetDir = target.position - transform.position;
if (Vector3.Angle(forward, targetDir) < shootAngleDistance){
 
 
    }
}


function Shoot() {
   
   
   
    lastShot = Time.time;
//    bulletposition2 = gameObject.transform.TransformPoint(Vector3.back * -3);
   
    Instantiate ( enemyBullet, transform.position, Quaternion.Euler (Vector3(0, -90,0) ));
    Instantiate ( enemyBullet2, transform.position, Quaternion.Euler (Vector3(0, 90,0) ));
}






function CanSeeTarget () : boolean
{
if (Vector3.Distance(transform.position, target.position) > attackRange)
    return false;

var hit : RaycastHit;
if (Physics.Linecast (transform.position, target.position, hit))
return hit.transform == target;

return false;
}

Although this may be more of a mistake I make myself, I suggest double-checking that the ‘player’ still has its tag set as ‘Player’, as I seem to forget to do this myself and chase thin air for a few minutes.

Hi,

I checked the player tag. it is attched to the player object. Any other suggestions?
