Pulling up a Rope

Hi Guys!

I made a physical rope, using empty gameobjects, hingeJoints and line renderer - and it is working remarkably well. However, I would like to be able to pull in the rope (like rolling up around your arm, and pulling up objects) and that.. I cannot do :(

I uses this code to generate the rope between two characters: using UnityEngine; using System.Collections; using System.Collections.Generic;

 public class RopeGeneratorScript : MonoBehaviour {
 
     private LineRenderer line;
     private List<GameObject> joints;
     private int vertexCount;
     private float NTDistance;
     public GameObject emptyPrefab;
     public GameObject neil;
     public GameObject thomas;
 
     // Use this for initialization
     void Start () {
         vertexCount = (((int)Vector3.Distance (neil.transform.position, thomas.transform.position))*4)-1;
         joints = new List<GameObject> ();
         line = GetComponent<LineRenderer> ();
         line.SetWidth (0.05f, 0.05f);
         line.SetColors (Color.black, Color.blue);
         for (int i = 0; i < vertexCount; i++) {
             joints.Add((GameObject)Instantiate(emptyPrefab, new Vector3(transform.position.x, transform.position.y, transform.position.z + (i+1)*0.25f), Quaternion.identity));
         }
         for(int j = 0; j < joints.Count-1; j++){
             joints[j].transform.parent = this.transform;
             joints[j].GetComponent<HingeJoint>().connectedBody = joints[j+1].rigidbody;
         }
         joints [0].AddComponent<HingeJoint>().connectedBody = thomas.rigidbody;
         joints [vertexCount - 1].GetComponent<HingeJoint> ().connectedBody = neil.rigidbody;
     }
     
     // Update is called once per frame
     void Update () {
         line.SetVertexCount (joints.Count);
         for(int i = 0; i < joints.Count; i++){
             line.SetPosition(i, joints[i].transform.position);
         }
     }
 }

As I said it works quite well - here is a screen of how it looks like:

Now picture one shows how it looks when its started - BUT in picture #2 I would like to be able to pull the lower character up, using the rope.. I tried extending and shorting the length of the rope, but it just didn't work very well at all - here is my attempt:

 void UpdateRobe(){
         int oldVertexCount = vertexCount;
         vertexCount = (((int)Vector3.Distance (neil.transform.position, thomas.transform.position))*4)-1;
 
         if (vertexCount == oldVertexCount) {
             return;
         } else if (vertexCount > oldVertexCount) {
             joints [oldVertexCount - 1].GetComponent<HingeJoint> ().connectedBody = null;
             int vertexDifference = vertexCount - oldVertexCount;
             for (int i = 0; i < vertexDifference; i++) {
                 joints.Add ((GameObject)Instantiate (emptyPrefab, new Vector3 (joints [oldVertexCount - 1].transform.position.x, joints [oldVertexCount - 1].transform.position.y, joints [oldVertexCount - 1].transform.position.z + (i + 1) * 0.25f), Quaternion.identity));
             }
             for (int j = oldVertexCount-1; j < vertexCount-1; j++) {
                 joints [j].transform.parent = this.transform;
                 joints [j].GetComponent<HingeJoint> ().connectedBody = joints [j + 1].rigidbody;
             }
                 joints [vertexCount - 1].GetComponent<HingeJoint> ().connectedBody = neil.rigidbody;
         } else if (vertexCount < oldVertexCount) {
             //int vertexDifference = oldVertexCount - vertexCount;
             joints[oldVertexCount-1].GetComponent<HingeJoint>().connectedBody = null;
             for(int k = oldVertexCount-1; k > vertexCount; k--){
                 Destroy(joints[k]);
                 joints.RemoveAt(k);
             }
             joints[vertexCount-1].GetComponent<HingeJoint>().connectedBody = neil.rigidbody;
         }
 
 
     }

So I was thinking if instead of making the rope longer and shorter than I could just wind it up and out, but I have no idea where to start really :O this is my first attempt with ropes so I on shaky ground as it is :)
