Snapping using kinect v2 sdk

this is my snapping script.

 using UnityEngine;
 using System.Collections;
 
 public class Snap : MonoBehaviour {
 
     public  string partnerTag;
     public  float closeVPDist = 0.05f;
     public float farVPDist = 1;
     public  float moveSpeed = 40.0f;
     public  float rotateSpeed = 90.0f;
 
     private Vector3 screenPoint;
     private Vector3 offset;
     private bool isSnaped;
     Color color = new Color(1, 0, 0);
 
     float dist = Mathf.Infinity;
     Color normalColor;
     GameObject partnerGO;
     // Use this for initialization
     void Start () {
         normalColor = GetComponent<Renderer>().material.color;
         partnerGO = GameObject.FindGameObjectWithTag(partnerTag);
     }
 
     void OnMouseDown()
     {
         screenPoint = Camera.main.WorldToScreenPoint(transform.position);
         offset = transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
         Cursor.visible = false;
     }
 
     void OnMouseDrag()
     {
         //transform.SetParent(null);
         Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
         Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
         transform.position = curPosition;
         Vector3 partnerPos = Camera.main.WorldToViewportPoint(partnerGO.transform.position);
         Vector3 myPos = Camera.main.WorldToViewportPoint(transform.position);
         dist = Vector2.Distance(partnerPos, myPos);
         GetComponent<Renderer>().material.color = (dist < closeVPDist) ? color : normalColor;
     }
 
     void OnMouseUp()
     {
         Cursor.visible = true;
         if (dist < closeVPDist)
         {
             transform.SetParent(partnerGO.transform);
             StartCoroutine(InstallPart());
             isSnaped = true;
         }
         if( dist > farVPDist)
         {
             //  transform.SetParent(null);
         }
     }
 
     IEnumerator InstallPart()
     {
         while (transform.localPosition != Vector3.right || transform.localRotation != Quaternion.identity)
         {
             transform.localPosition = Vector3.MoveTowards(transform.localPosition, Vector3.right, Time.deltaTime * moveSpeed);
             transform.localRotation = Quaternion.RotateTowards(transform.localRotation, Quaternion.identity, Time.deltaTime * rotateSpeed);
             yield return new WaitForEndOfFrame();
         }
     }
 }

it works fine with mouse controling.
