Shower spiral cable simulation

Questions & Answers
1

I’m trying to simulate a shower spiral cable like in the picture blow. [188357-sh1.png*_|188357]. I tried all the Joints for the movement and rotation of the bones but couldn’t do what I wanted. Finally, I wrote a script for the transforms of the bones, but here, too, I couldn’t manage to calculate the rotations of the bones depending on their movements.

using UnityEngine;

public class SetTransforms : MonoBehaviour
{
    [SerializeField] float force = .033f;
    GameObject[] bones;
    Vector3 diffPos, pos1, pos2;
    Vector3 diffRot, rot1, rot2;
    int numBones;
    // Start is called before the first frame update
    void Start()
    {
        numBones = transform.childCount;

        bones = new GameObject[numBones];

        for (int i=0; i<numBones; i++)
        {
            bones *= transform.GetChild(i).gameObject;*

}

diffPos = new Vector3(0, 0, 0);
pos1 = pos2 = bones[0].transform.position;
}

// Update is called once per frame
void Update()
{
pos1 = bones[0].transform.position;
rot1 = bones[0].transform.eulerAngles;

diffPos = pos1 - pos2;

diffRot = (rot1 - rot2);// * Mathf.PI / 180;

diffPos = diffPos + diffRot;

if (pos1 != pos2) SetPos();

pos2 = pos1;
rot2 = rot1;
}

void SetPos()
{
for (int i=1; i<numBones; i++)
{
Vector3 pos = bones.transform.position + diffPos * force * ((float)numBones - (float)i);
//Vector3 rot = bones.transform.eulerAngles + diffRot * force * ((float)numBones - (float)i);
//bones*.transform.position = _pos;*

bones*.transform.position = pos;*
}
}
}_

I would be grateful if you help.
