Grappling hook script not working, HELP!

I'm using this script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class GrapplingHook : MonoBehaviour {
 
     private bool grappling;
     private HingeJoint grabHinge;
     RaycastHit hit;
     public float range;
     GameObject parent;
     Vector3 reposition;
     GameObject positioning;
     GameObject player;
 
     void Awake () {
         parent = GameObject.Find ("FirstPersonCharacter");
         positioning = GameObject.Find ("Transform");
         reposition = positioning.transform.position;
         player = GameObject.Find ("FPSController");
     }
     void Update () {
         if (Input.GetButtonDown("Fire2")) {
             grappling = true;
             GrapplingShot ();
         }
         if (Input.GetButtonUp ("Fire2")) {
             grappling = false;
         }
         if (grappling == false) {
             positioning.GetComponent<RopeForHook>().line.enabled = false;
             transform.position = reposition;
             transform.parent = parent.transform;
 
         }
     }
     //To shoot your hook, call this method:
     void GrapplingShot(){
         if (grappling == true) {
             transform.parent = null;
             Physics.Raycast (transform.position, transform.forward, out hit, range);
             transform.position = hit.point;
             positioning.GetComponent<RopeForHook>().Rope ();
             if (Input.GetKey ("q")) {
                 player.transform.position = Vector3.MoveTowards (player.transform.position, hit.point, 1);
                 }
             }
         }
     }
 

For a grappling hook and this:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class RopeForHook : MonoBehaviour {
 
     public LineRenderer line;
     GameObject hook;
 
     void Awake () {
         line = GetComponent<LineRenderer> ();
         hook = GameObject.Find ("Grappling Hook");
     }
 
     void Update () {
         
     }
     public void Rope () {
         line.enabled = true;
         line.SetPosition (0, hook.transform.position);
     }
 }
 

For the rope. However, when I test it, the hook doesn't move with the player, although it sort of follows the player's rotation. The hook also shoots on a weird diagonal angle to the player, the "reel-in" part does nothing and the rope shoots straight out behind the player. There is obviously something very wrong with my script, and I can't find it after meticulous trial-and-error searching. Please help me fix this!
