Unity 2D Grapple hook problems

Questions & Answers
1

I’m making a simple 2D platformer game and would like to make a grappling hook that the player can use by clicking in a certain game object.
I’ve followed Wabble - Unity tutorials, tutorial (DonHaul Game Dev - Wabble - Unity Tutorials - YouTube) I’ve followed the tutorial and copied the code correctly but it doesn’t seem to work.
Does anyone know how to fix it?

Here’s the code I’m currently using:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Rope_Placement : MonoBehaviour
{

    DistanceJoint2D Joint;
    Vector3 targetPos;
    RaycastHit2D hit;
    public float distance = 10f;
    public LayerMask Mask;

    // Start is called before the first frame update
    void Start()
    {
        Joint = GetComponent<DistanceJoint2D> ();
        Joint.enabled = false;
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButtonDown(1))
        {
            targetPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            targetPos.z = 0;

            hit = Physics2D.Raycast(transform.position, targetPos - transform.position,distance,Mask);

            if (hit.collider!=null && hit.collider.gameObject.GetComponent<Rigidbody2D>() !=null)
            {
                Joint.enabled = true;
                Joint.connectedBody = hit.collider.gameObject.GetComponent<Rigidbody2D>();
                Joint.distance = Vector2.Distance(transform.position,hit.point);
            }
        }

        if (Input.GetMouseButtonUp(1))
        {
            Joint.enabled = false;
        }
    }
}
