How do I make the length of my rope shorter

Questions & Answers
1

I picked up some code from a video that explained how to incorporate rope physics into my 2D game. Everything works as intended except for the fact that the length of the rope is too large for the small testing space that I made to present my game in. Basically, I am trying to cut the length of the rope down so I could start swinging earlier, but I do not know how to do so. Any help for this truly appreciated.

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

public class Rope : MonoBehaviour {
    public GameObject ropeShooter;
    private SpringJoint2D rope;
    public int maxRopeFrameCount;
    private int ropeFrameCount;

    public LineRenderer lineRenderer;
	// Use this for initialization
	void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
		if (Input.GetMouseButtonDown(0))
        {
            Fire();
        }
	}

    void FixedUpdate()
    {
        if (rope != null)
        {
            lineRenderer.enabled = true;
            lineRenderer.positionCount = 2;
            lineRenderer.SetPosition(0, ropeShooter.transform.position);
            lineRenderer.SetPosition(1, rope.connectedAnchor);
        }
        else
        {
            lineRenderer.enabled = false;
        }
    }
    void Fire()
    {
        Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        Vector3 position = ropeShooter.transform.position;
        Vector3 direction = mousePosition;
        RaycastHit2D hit = Physics2D.Raycast(mousePosition,direction,Mathf.Infinity);

        if (hit.collider != null)
        {
            SpringJoint2D newRope = ropeShooter.AddComponent<SpringJoint2D>();
            newRope.enableCollision = true;
            newRope.frequency = .2f;
            newRope.connectedAnchor = hit.point;
            newRope.enabled = false;
            GameObject.DestroyImmediate(rope);
            rope = newRope;
            ropeFrameCount = 0;

        }
    }
}

Also, here is a link to that youtube video I mentioned: Unity 2D Basic Rope Swinging Physics - YouTube

have you tried using the method “transform.localScale”

Hre is a an example code for 3d transform.localScale += new Vector3(0.1F, 0, 0);

To make it for 2d just change Vector3 to Vector2 and delete one of the axes. Your code should look something like that:

 transform.localScale += new Vector2(0, 0);
