Why is my turret not shooting

bulletSpawn = transform.Find ("bulletSpawn"); // only works if bulletSpawn is a turret child!
}

if (other.tag == "Enemy"){ // only enemies are added to the target list!
targets.Add(other.transform);
}
}

void OnTriggerExit(Collider other){
if (other.tag == "Enemy"){
targets.Remove(other.transform);
}
}

void TargetEnemy(){
if (selectedTarget == null){ // if target destroyed or not selected yet...
if (targets.Count > 0) selectedTarget = targets[0];
}
}

void SortTargetsByDistance(){
targets.Sort(delegate(Transform t1, Transform t2){
return Vector3.Distance(t1.position, myTransform.position).CompareTo(Vector3.Distance(t2.position, myTransform.position));
});
}

void Update(){
Debug.Log ("shooting");
BulletScript script = GetComponent<BulletScript>();
TargetEnemy(); // update the selected target and look at it
if (selectedTarget){ // if there's any target in the range...
transform.LookAt(selectedTarget); // aim at it
if (Time.time >= shootTime){ // if it's time to shoot...
Rigidbody bullet = (Rigidbody)Instantiate(bulletPrefab, bulletSpawn.position, bulletSpawn.rotation);
bullet.AddForce(transform.forward*speed); // shoot in the target direction
shootTime = Time.time + shotInterval; // set time for next shot
}
}

I had a quick look at the script and it seems the reason is because the enemies are not being added to the array, the reason was because the enemies entering the trigger need to be rigidbodies, you can make them kinematic so it doesnt change anything for your game. Give that a whirl.

EDIT: after taking a closer look at the actual shooting which wasnt working either, I found that the bulletspawn variable was being wiped after the script was started so removing:

bulletSpawn = transform.Find ("bulletSpawn"); // only works if bulletSpawn is a turret child!

and applying the bulletspawn manually afterwards worked for me.

 

Thanks for helping but I had change my target to 1 in my array and attach the bullet script to my turret but it is still not working.

Edited:how do i apply the bulletspawn manually
