Zigfu Update status

I always wonder how do I update my zigfu updater? I cannot called it at my update function. Please help me out for this.

 void Start () {
         KK = GameObject.Find ("Blockman").GetComponent<Kick> ();
         ball = GameObject.Find ("Ball");
     }
     
     // Update is called once per frame
     void Update () {
 
 
 
     }
 
     void OnTriggerEnter(Collider col){
         if (col.gameObject.name == "LeftFoot") {
             Debug.Log("Leftfoot");
             //KK.OnLeftkicking();
             ball.rigidbody.AddForce(leftFootVelocity);
         }
         if (col.gameObject.name == "RightFoot") {
             //KK.OnRightkicking();
             Debug.Log("Rightfoot");
             ball.rigidbody.AddForce(rightFootVelocity);
         }
     }
 
     public void Zig_UserUpdate(ZigTrackedUser user)
     {
         if (user.Id == trackingId) {
             oldLeftFoot = currLeftFoot;
             oldRightFoot = currRightFoot;
             
             if (user.SkeletonTracked) {
                 
                 
                 currLeftFoot = user.Skeleton[(int)ZigJointId.LeftFoot].Position;
                 
                 
                 currRightFoot = user.Skeleton[(int)ZigJointId.RightFoot].Position;
                 
                 
                 //currLeftHand = user.Skeleton[(int)ZigJointId.LeftHand].Position;
                 
                 /*ZigInputJoint torso = user.Skeleton[(int)ZigJointId.Torso];
 
                 Vector3 calculated = origin.position - torso.Position;
                 Debug.Log ("distance compared: " + calculated);*/
 
                 rightFootVelocity = (currRightFoot - oldRightFoot) * 100;
                 leftFootVelocity = (currLeftFoot - oldLeftFoot) * 100;
                 
                 Debug.Log ("Right V: " + currRightFoot.ToString());
                 Debug.Log ("Left V: "  + currLeftFoot.ToString());
 
                 Vector3 LF = currLeftFoot;
                 Vector3 RF = currRightFoot;
                 LF.z *= 10000;
                 RF.z *= 10000;
                 LF.x *= 1000;
                 LF.y *= 1000;
                 RF.y *= 1000;
                 RF.x *= 1000;
             }
         }
     }
