I want my camera to move only Y axis and my character to rotate with my camera

This is my code for my camera

     public Camera cam;
 public Transform target;
 public float distance = 5.0f;
 public float ySpeed = 120.0f;
 public float yMinLimit = -20f;
 public float yMaxLimit = 80f;
 public float distanceMin= 0.5f;
 public float distanceMax= 15f;

 public Rigidbody rigidbody;

 float y = 0.0f;

 void Start(){
     Vector3 angles = transform.eulerAngles;
     y = angles.x;

     if (rigidbody != null) {
         rigidbody.freezeRotation = true;
     }

 }

 void LateUpdate(){
     if (target) {
         y -= Input.GetAxis ("Mouse Y") * ySpeed * 0.02f;
         y = ClampAngle (y, yMinLimit, yMaxLimit);

         Quaternion rotation = Quaternion.Euler (y, 0, 0);
         distance = Mathf.Clamp (distance - Input.GetAxis ("Mouse ScrollWheel") * 5, distanceMin, distanceMax);

         RaycastHit hit;
         if (Physics.Linecast (target.position, transform.position, out hit)) {
             distance -= hit.distance;
         }
         Vector3 negDistance = new Vector3 (0.0f, 0.0f, -distance);
         Vector3 position = rotation * negDistance + target.position;
         transform.rotation = rotation;
         transform.position = position;

     }
 }

 public static float ClampAngle(float angle,float min,float max){
     if (angle < -360f)
         angle += 360f;
     if (angle > 360f)
         angle -= 360f;
     return Mathf.Clamp (angle, min, max);
 }

} And this is my code for my character movement

     public float skorost = 1.0f;
 public float zavurtane = 1.0f;




 // Use this for initialization
 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {
     float translation = Input.GetAxis ("Vertical") * skorost;
     float r = zavurtane * Input.GetAxis ("Mouse X");
     translation *= Time.deltaTime;
     transform.Translate (0f, 0f, translation);
     transform.Rotate (0f, r, 0f);

     }

Now my character rotate when i move my mouse but my camera dont follow my character rotation. Pls help ! :)
