Resolved LaserBeam Reflection (RaycastHit2D)was not working like expected and didnt reflect correctly

I'm trying to simulate the laser reflection, this partially works,
however it doesn't work across the entire collider.
But only in places.

I've attached four images that effectively illustrate the problem I'm encountering.
And a image from the settings of my LineRenderer.

The laser hits exactly at a certain point of the collider, but not at all other points.
I'm confused by this inconsistency.

Interestingly, I've also implemented a GrapplingLogic function that I use to pre-emptively check if a hookshot collides with anything at a given distance.
This RaycastHit2D works perfectly.

So now I'm at a loss as to what could be the issue.


Here my GrabblingSystem which is working
(just for demonstrating)

Code (CSharp):

1.  Vector3 GetCollisionPoint(Vector3 directionToCursor)
2.     {
3.         Vector3 startPosition = player.position;
4.  
5.         RaycastHit2D hit = Physics2D.Raycast(startPosition, directionToCursor.normalized, hookRange, LayerMask.GetMask("Ground"));
6.  
7.         if (hit.collider != null)
8.         {
9.             return hit.point;
10.         }
11.  
12.         return Vector3.zero;
13.     }

Here my Laser Reflection Code
(where i need help)

Code (CSharp):

1.  IEnumerator ReflectLaser()
2.     {
3.         Vector3 raycastOrigin = laserBeam.transform.position;
4.         Vector3 raycastDirection = laserBeam.transform.right;
5.         laserBeam.positionCount = 1;
6.         laserBeam.SetPosition(0, raycastOrigin);
7.  
8.         float remainLength = defaultLength;
9.         int groundLayerMask = LayerMask.GetMask("Ground");
10.  
11.         for (int i = 0; i < numOfReflections; i++)
12.         {
13.             RaycastHit2D hit = Physics2D.Raycast(raycastOrigin, raycastDirection, remainLength, groundLayerMask);
14.  
15.             if (hit.collider != null)
16.             {
17.                 laserBeam.positionCount += 1;
18.                 laserBeam.SetPosition(laserBeam.positionCount - 1, hit.point);
19.                 remainLength -= Vector2.Distance(raycastOrigin, hit.point);
20.                 raycastOrigin = hit.point;
21.                 raycastDirection = Vector2.Reflect(raycastDirection, hit.normal);
22.             }
23.             else
24.             {
25.                 laserBeam.positionCount += 1;
26.                 laserBeam.SetPosition(laserBeam.positionCount - 1, raycastOrigin + (raycastDirection * remainLength));
27.                 break; // No more reflections if no collision is detected.
28.             }
29.         }
30.         yield return new WaitForSeconds(laserSpeed);
31.         laserBeam.SetPosition(0, raycastOrigin);
32.         laserBeam.SetPosition(1, raycastOrigin);
33.         laserBeam.SetPosition(2, raycastOrigin);
34.     }

fixed by using:

Code (CSharp):

1. raycastOrigin = hit.collider.ClosestPoint(raycastDirection);

Instead of:

Code (CSharp):

1. raycastOrigin = hit.point;

 

I accidentally fixed it by using:

Code (CSharp):

1. raycastOrigin = hit.collider.ClosestPoint(raycastDirection);

Instead of:

Code (CSharp):

1. raycastOrigin = hit.point;

now it uses the closestPoint and it is reflecting correctly.



Regarding your question:

The image showed one working reflection and one that didn't work. Normally reflections should always occur and always come out at the same angle as they came in, but I believe my previous version allowed the same collider for the reflection direction and so in some cases actually used it instead of bouncing off it.
Anyway, it works as expected and I thank you for your answer and help.
