Enemys jittering when moving

Hey guys, my game is not a rigidbody based game, so when I set the camera movement and the player movement to FixedUpdate, the player goes perfectly smooth, but the enemys now stutter. Does someone know how i can fix that. (It'a a 3D game)

The cameraMotor script:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class CameraMotor : MonoBehaviour { public Transform LookAt;

public float boundX = 0.5f; public float boundY = 0.5f; public float boundZ = 0.5f; public float speed = 0.15f;

private Vector3 desiredPosition;

 // Update is called once per frame
 void FixedUpdate()
 {
   Vector3 delta = Vector3.zero;

   float dx = LookAt.position.x - transform.position.x;

   // X Axis
   if (dx > boundX || dx < -boundX)
   {
     if (transform.position.x < LookAt.position.x)
     {
       delta.x = dx - boundX;
     }
     else
     {
       delta.x = dx + boundX;
     }
   }

   float dy = LookAt.position.y - transform.position.y;

   // Y Axis
   if (dy > boundX || dy < -boundY)
   {
     if (transform.position.y < LookAt.position.y)
     {
       delta.y = dy - boundY;
     }
     else
     {
       delta.y = dy + boundY;
     }
   }

   float dz = LookAt.position.z - transform.position.z;

   // Z Axis
   if (dz > boundZ || dz < -boundZ)
   {
     if (transform.position.z < LookAt.position.z)
     {
       delta.z = dz - boundZ;
     }
     else
     {
       delta.z = dz + boundZ;
     }
   }

   // Move the camera
   desiredPosition = transform.position + delta;
   transform.position = Vector3.Lerp (transform.position, desiredPosition, speed);



 }

}

the playerMovement script:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Movement : MonoBehaviour { //Variables public CharacterController controller; public float gravity = -9.81f; public Transform groundCheck; public float groundDistance = 0.4f; public LayerMask groundMask; public float jumpHeight = 3f; public float speed;

Vector3 velocity; bool isGrounded; private bool canDoubleJump;

void FixedUpdate() {

   //Gravity & GroundCheck
   isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);

   if(isGrounded && velocity.y < 0)
   {
     velocity.y = -4f;
   }


   //Movement
   float x = Input.GetAxisRaw("Horizontal");
   float z = Input.GetAxisRaw("Vertical");

    Vector3 move = transform.right * x + transform.forward * z;

   velocity.y += gravity * Time.deltaTime;
   controller.Move(move * speed * Time.deltaTime);
   controller.Move(velocity * Time.deltaTime);


   //Jump / DoubleJump
   if(isGrounded)
   {
     canDoubleJump = true;
   }

   if(Input.GetButtonDown("Jump"))
   {
     if (isGrounded) {
     velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
   } else {
     if (canDoubleJump == true) {
     velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
     canDoubleJump = false;
     }
   }


 }

} }

The enemy AI script:

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.AI; using EZCameraShake;

public class EnemyAI : MonoBehaviour { public NavMeshAgent agent; public Transform player; public LayerMask whatIsGround, whatIsPlayer; public float damage = 10f; public float range = 10000f;

 public float magnitude;
 public float roughness;
 public float fadeInTime;
 public float fadeOutTime;

 public GameObject firingpoint;

 bool alreadyAttacked;

 //Patroling
 public Vector3 walkPoint;
 bool walkPointSet;
 public float walkPointRange;

 //Attacking
 public float timeBetweenAttacks;

 //States
 public float sightRange, attackRange;
 public bool playerInSightRange, playerInAttackRange;


 private void Update()
 {
     //Check for sight and attack range
     playerInSightRange = Physics.CheckSphere(transform.position, sightRange, whatIsPlayer);
     playerInAttackRange = Physics.CheckSphere(transform.position, attackRange, whatIsPlayer);

     if (!playerInSightRange && !playerInAttackRange) Patroling();
     if (playerInSightRange && !playerInAttackRange) ChasePlayer();
     if (playerInAttackRange && playerInSightRange) AttackPlayer();

     if (playerInSightRange){
       Vector3 playerPosition = new Vector3(player.transform.position.x, transform.position.y, player.transform.position.z);
       transform.LookAt(playerPosition);
     }
 }

 private void Patroling()
 {
     if (!walkPointSet) SearchWalkPoint();

     if (walkPointSet)
         agent.SetDestination(walkPoint);

     Vector3 distanceToWalkPoint = transform.position - walkPoint;

     //Walkpoint reached
     if (distanceToWalkPoint.magnitude < 1f)
         walkPointSet = false;
 }
 private void SearchWalkPoint()
 {
     //Calculate random point in range
     float randomZ = Random.Range(-walkPointRange, walkPointRange);
     float randomX = Random.Range(-walkPointRange, walkPointRange);

     walkPoint = new Vector3(transform.position.x + randomX, transform.position.y, transform.position.z + randomZ);

     if (Physics.Raycast(walkPoint, -transform.up, 2f, whatIsGround))
         walkPointSet = true;
 }

 private void ChasePlayer()
 {
   transform.LookAt(player);
   transform.Translate(Vector3.forward*7*Time.deltaTime);
 }

 private void AttackPlayer()
 {

     if (!alreadyAttacked)
     {
         Shoot();
         alreadyAttacked = true;
         Invoke(nameof(ResetAttack), timeBetweenAttacks);

     }
 }

 private void ResetAttack()
 {
     alreadyAttacked = false;
 }

 void Shoot()
 {

   RaycastHit hit;
   if (Physics.Raycast(firingpoint.transform.position, firingpoint.transform.forward, out hit, range))
   {
     Debug.Log(hit.transform.name);

   DamageObject target = hit.transform.GetComponent<DamageObject>();
   if (target != null)
   {
     target.TakeDamage(int damage);
     CameraShaker.Instance.ShakeOnce(magnitude, roughness, fadeInTime, fadeOutTime);
   }

 }
 }
 public void OnDrawGizmosSelected()
 {
     Gizmos.color = Color.red;
     Gizmos.DrawWireSphere(transform.position, attackRange);
     Gizmos.color = Color.yellow;
     Gizmos.DrawWireSphere(transform.position, sightRange);
 }

I really hope someone know how i can fix that.
