I have a rope generated by pure code in a script to do a fishing line, the problem here is when i put the fishing buoy on the rope tip, the rope stretches infinitely and i want the buoy hanging
Thanks in advance
Here is my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class hiloCanya : MonoBehaviour
{
private LineRenderer lineRenderer;
private List hiloSegmentos = new List();
private float hiloSegLen = 0.25f;
private int segmentoLength = 35;
private float lineWidth = 0.05f;
[SerializeField] private Transform startPoint;
[SerializeField] private Transform endPoint;
// Use this for initialization
void Start()
{
this.lineRenderer = this.GetComponent();
Vector3 hiloStartPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);
for (int i = 0; i < segmentoLength; i++)
{
this.hiloSegmentos.Add(new HiloSegmento(hiloStartPoint));
hiloStartPoint.y -= hiloSegLen;
}
}
// Update is called once per frame
void Update()
{
this.DrawRope();
}
private void FixedUpdate()
{
this.Simulate();
}
private void Simulate()
{
// SIMULACION
Vector2 fuerzaGravedad = new Vector2(0f, -1.5f);
for (int i = 1; i < this.segmentoLength; i++)
{
HiloSegmento primerSegmento = this.hiloSegmentos[i];
Vector2 velocidad = primerSegmento.posNow - primerSegmento.posOld;
primerSegmento.posOld = primerSegmento.posNow;
primerSegmento.posNow += velocidad;
primerSegmento.posNow += fuerzaGravedad * Time.fixedDeltaTime;
this.hiloSegmentos[i] = primerSegmento;
}
//CONSTRAINTS
for (int i = 0; i < 50; i++)
{
this.ApplyConstraint();
}
}
private void ApplyConstraint()
{
//Constrant to Mouse
/* HiloSegmento primerSegmento = this.hiloSegmentos[0];
primerSegmento.posNow = Camera.main.ScreenToWorldPoint(Input.mousePosition);
this.hiloSegmentos[0] = primerSegmento; */
//objeto para el principio del hilo
HiloSegmento primerSegmento = this.hiloSegmentos[0];
primerSegmento.posNow = this.startPoint.position;
this.hiloSegmentos[0] = primerSegmento;
//objeto para el final del hilo
HiloSegmento finalSegmento = this.hiloSegmentos[this.segmentoLength - 1];
finalSegmento.posNow = this.endPoint.position;
this.hiloSegmentos[this.segmentoLength - 1] = finalSegmento;
for (int i = 0; i < this.segmentoLength - 1; i++)
{
HiloSegmento primerSeg = this.hiloSegmentos[i];
HiloSegmento segundoSeg = this.hiloSegmentos[i + 1];
float dist = (primerSeg.posNow - segundoSeg.posNow).magnitude;
float error = Mathf.Abs(dist - this.hiloSegLen);
Vector2 changeDir = Vector2.zero;
if (dist > hiloSegLen)
{
changeDir = (primerSeg.posNow - segundoSeg.posNow).normalized;
} else if (dist < hiloSegLen)
{
changeDir = (segundoSeg.posNow - primerSeg.posNow).normalized;
}
Vector2 changeAmount = changeDir * error;
if (i != 0)
{
primerSeg.posNow -= changeAmount * 0.5f;
this.hiloSegmentos[i] = primerSeg;
segundoSeg.posNow += changeAmount * 0.5f;
this.hiloSegmentos[i + 1] = segundoSeg;
}
else
{
segundoSeg.posNow += changeAmount;
this.hiloSegmentos[i + 1] = segundoSeg;
}
}
}
private void DrawRope()
{
float lineWidth = this.lineWidth;
lineRenderer.startWidth = lineWidth;
lineRenderer.endWidth = lineWidth;
Vector3[] posicionesHilo = new Vector3[this.segmentoLength];
