How can I add collider to my line renderer

I am making a swinging game based on spider man style. Problem is when line attached to wall and ı am started to swinging, line is passing inside of walls. Phsyic does not working. How can ı solve this ? Thanks for help

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

namespace Rope {
    public class GrapplingRope : MonoBehaviour {
        [Header("Values")]
        public AnimationCurve effectOverTime;
        public AnimationCurve curve;
        public AnimationCurve curveEffectOverDistance;
        public float curveSize;
        public float scrollSpeed;
        public float segments;
        public float animSpeed;


        [Header("Data")]
        public LineRenderer lineRenderer;

        private Vector3 _start;
        private Vector3 _end;
        private float _time;
        private bool _active;

        public void UpdateGrapple() {
            lineRenderer.enabled = _active;
            if (_active)
                ProcessBounce();
        }


        private void ProcessBounce() {
            var vectors = new List<Vector3>();



            _time = Mathf.MoveTowards(_time, 1.4f,
                Mathf.Max(Mathf.Lerp(_time, 1.5f, animSpeed * Time.deltaTime) - _time, 1.5f * Time.deltaTime));

            vectors.Add(_start);
           

            var forward = Quaternion.LookRotation(_end - _start);
            var up = forward * Vector3.up;

            for (var i = 1; i < segments + 1; i++) {
                var delta = 1f / segments * i;
                var realDelta = delta * curveSize;
                while (realDelta > 1f) realDelta -= 1f;
                var calcTime = realDelta + -scrollSpeed * _time;
                while (calcTime < 0f) calcTime += 1f;

                var defaultPos = GetPos(delta);
                var effect = Eval(effectOverTime, _time) * Eval(curveEffectOverDistance, delta) * Eval(curve, calcTime);

                vectors.Add(defaultPos + up * effect);
            }

            lineRenderer.positionCount = vectors.Count;
            lineRenderer.SetPositions(vectors.ToArray());
        }

        private Vector3 GetPos(float d) {
            return Vector3.Lerp(_start, _end, d);
        }

        private static float Eval(AnimationCurve ac, float t) {
            return ac.Evaluate(t * ac.keys.Select(k => k.time).Max());
        }

        public void Grapple(Vector3 start, Vector3 end) {


            _active = true;
            _time = 1f;


            _start = start;
            _end = end;
        }





        public void UnGrapple() {
            _active = false;
        }

        public void UpdateStart(Vector3 start) {

            _start = start;
        }

        public bool Grappling => _active;
    }
}

A line renderer is just that : a renderer.

If you want realistic rope physics you’ll have to either build up a rope using physics joints or use something off the asset store like Obi Rope: Obi Rope | Physics | Unity Asset Store

It will not be as simple as “adding a collider”.

What Praetor said… mostly… but there is this API:

You can bake the current internal mesh the LR is using and put that in your own MeshCollider.

BUT! I don’t think it will work well for a rope or moving stuff. The reason is to do that you will need a Rigidbody on that object as well, and you will be effectively doing the BakeMesh every frame, and this injecting fresh colliders into it, so I don’t think any of the collisions would be reliable if the rope was moving. Injecting a fresh collider each frame is going to startle the physics engine in a way that will lead you to results like the GTA IV Swingset Of Death (google for yourself).

But you could raycast to the MeshCollider, or you could bake the mesh and use it to collide against from OTHER Rigidbodies hitting it, such as making a boundary or floor out of the LR.

Baking the mesh on a line renderer will just give you a rigid solid rod though. It won’t handle bending or stretching at all!

when my character swinging

I tried and it happened like gta4. İt did not worked. I think there is no way at now to add phsyic to line renderer ?

My game is 3d. I am not sure this will work for 3d. Still ı will try thanks

I’m also looking for a 3d Collider solution. It would be great to know if you found a solution yet?
