Hi , I have a problem with my script. When i nothing click camera is smooth . But i want when i will click right mouse button, run Camera orbit function;
The problem is that when i click RMB camera is not good . Camera does not charge current position .

This is my script :

Should be added to the camera.
transform Target is Player;

Use code tags. We’re lazy folks here:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class cameracontroler : MonoBehaviour {
    //if nothing click
    public Transform target;
    public float smoothTime = 0.3F;
    private Vector3 velocity = Vector3.zero;
    public float cameraxx = 0f;
    public float camerayy =2f;
    public float camerazz = -4f;
  
    //CameraOrbit()
    private Vector3 _cameraOffset;
    public Transform PlayerTransform;
    [Range(0.01f, 1.0f)]
    public float SmoothFactor = 0.5f;
   public float RotationsSpeed = 5.0f;
  
    void Start() {
        _cameraOffset = transform.position - target.position;
    }
    void LateUpdate()
    {
  
        if (Input.GetMouseButton(1)) {
            cameraorbit();
        }
        else {
            camerasmooth();
        }
    }
    void cameraorbit() {
            Quaternion camTurnAngle =
             Quaternion.AngleAxis(Input.GetAxis("Mouse X") * RotationsSpeed, Vector3.up);
            _cameraOffset = camTurnAngle * _cameraOffset;
          
        Vector3 newPos = target.position + _cameraOffset;
        transform.position = Vector3.Slerp(transform.position, newPos, SmoothFactor);
        transform.LookAt(target);
      
          
    }
    void camerasmooth() {
        // Define a target position above and behind the target transform
      
        Vector3 targetPosition = target.TransformPoint(new Vector3(cameraxx, camerayy, camerazz));
      
        // Smoothly move the camera towards that target position
        transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref velocity, smoothTime);
        transform.LookAt(target);
    }
}

Note that you’re using Vector3.Slerp incorrectly.
It expects you to feed percentage of the transition between point A and B.

Try using Vector3.MoveTowards instead, if you need movement interpolation like so:

transform.position = Vector3.MoveTowards(transform.position, newPos, SmoothFactor * Time.deltaTime);

Or, if you do want to use Slerp, do the following:

[SerializeField]
private float _orbitTransitionDuration = 1f;

private float _lerpStartTime;
private Vector3 _initialPosition;

private bool _doLerp;

// In Update
if (Input.GetButtonDown(1)){
    _lerpStartTime = Time.time; // Record time when the lerp has started
    _initialPosition = transform.position; // And the point A for the lerp

    // Could as well setup a flag, just in case
    _doLerp = true;
}

// In the orbit method
if (_doLerp) {
    float percentage = (Time.time - _lerpStartTime) / _orbitTransitionDuration; // Calculate percentage of how much time left for the lerp
    transform.position = Vector3.Slerp(_initialPosition, target.position, percentage); // Transition between starting lerp point to the target point

    if (percentage >= 1f) _doLerp = false; // Done lerping
}

Note don’t forget to lerp camera position back when you’re done.
