    I've written code blocks for turrets and a target on a sphere.
    See the attached files for a sample picture.
    My goal is that Turret_1 and Turret_2 aim at the target continuously. Turret_1 and Turret_2 rotate only on the y-axis. The target spins around the sphere. I couldn't solve the problem in my script. Turret_2 does not move at all. Turret_1 is aiming at the target but if the target is moving towards turret_1, it is not aiming at the target.

    Code (CSharp):
    1. public class Target : MonoBehaviour {
    2.  
    3.     public float targetSpeed;
    4.    
    5.     void Update () {
    6.         transform.RotateAround(Vector3.zero, transform.right, targetSpeed * Time.deltaTime);
    7.     }
    8. }
    Code (CSharp):
    1. public class Turret : MonoBehaviour {
    2.  
    3.     public Transform target;
    4.     public float rotateSpeed;
    5.  
    6.     private Rigidbody rb;
    7.     private Vector3 direction;
    8.     private float rotateAmount;
    9.  
    10.     void Start () {
    11.         rb = GetComponent<Rigidbody>();
    12.     }
    13.    
    14.     void Update () {
    15.         TurretDirection();
    16.     }
    17.  
    18.     void TurretDirection()
    19.     {
    20.         direction = target.position - transform.position;
    21.         direction.Normalize();
    22.         rotateAmount = Vector3.Cross(direction, transform.forward).y;
    23.         rb.angularVelocity = -rotateSpeed * rotateAmount * transform.up;
    24.     }
    25. }

    This may not be right, but it doesn't look like you are updating the target. Have you tried putting
    transform.LookAt(target); 
    in the Update?

    Didn't say it was wrong. Maybe this would help you more forum.unity.com/threads/unity-turret-tutorial.341866/
