Cant made the object do smthing after its not in raycast anymore

if(Physics.Raycast (camera.transform.position, fwd, out raycast, distance) & raycast.transform.tag == "Object")
            {
                if(raycast.rigidbody)
                {

                    PlayerPrefs.SetString("PulledObj", this.raycast.transform.name);
                    if(Input.GetMouseButton(1))
                    {              
                        this.gravObj.GetComponent<Rigidbody>().AddForce((camera.transform.position-raycast.transform.position).normalized*pullForce/50,ForceMode.VelocityChange);
                        if(raycast.distance<stopDistance)
                        {
                            this.raycast.transform.GetComponent<Rigidbody>().velocity = Vector3.zero;
                            this.raycast.transform.GetComponent<Rigidbody>().Sleep();
                            this.raycast.transform.GetComponent<Rigidbody>().useGravity=false;
                            this.raycast.transform.SetParent(gravyGun.transform);
                            this.raycast.transform.rotation = Quaternion.Slerp(raycast.transform.rotation, Quaternion.LookRotation(camera.transform.position - raycast.transform.position), 100f * Time.deltaTime);
                            click=2;
                        } 
                    }
             
                else if(raycast.rigidbody==null)
            {
                    this.gravObj.transform.GetComponent<Rigidbody>().useGravity=true;
                    this.gravObj.transform.parent=null; 
                    click=1;
            }                                
            }
