Reflecting lasers on a mirror with a collider?

Questions & Answers
1

I am a beginner in Unity.
So I have implemented the following script with the help of some tutorials to create a laser using line renderer and raycasting. The laser comes in fine but the reflection is confusing and is happening but the direction that it takes I cant understand. If someone could help it shall be great!!

I have the following questions-

  1. Does this code look correct for my required application?

  2. The reflections I am getting are pretty random and are not along the surface normals. Could there be something during modelling that could be causing this incorrect surface reflections?

  3. Using LaserLine.SetPosition (NumOfVert, pos); after the second vector onwards reduces the width of my laser, what could be the reason for this? But if i dont use that the laser still reflects but i dont know in what direction and based on what criteria, BUT its width remains

             using UnityEngine;
 using System;
 using System.Collections;

 public class LaserTip_LaserScript : MonoBehaviour 
 {
 	int NumOfVert;
 	LineRenderer LaserLine;
 	Light FlareLight;
 	Ray LaserRay;
 	float LaserWidth= 0.05f;

 

 	void Start () 
 	{
 		LaserLine = gameObject.GetComponent<LineRenderer> ();
 		LaserLine.enabled = false;

 		FlareLight= gameObject.GetComponent<Light> ();
 		FlareLight.enabled = false;

 	}
 	
 	// Update is called once per frame
 	void Update () 
 	{

 		if( Input.GetButtonDown("Fire1") )
 		{
 			LaserLine.SetWidth (LaserWidth, LaserWidth);
 			NumOfVert = 1;
 			LaserRay=	new Ray( transform.position, transform.forward);

 			StopCoroutine("FireLaser");
 			StartCoroutine("FireLaser");
 		}
 	}

 	IEnumerator FireLaser()
 	{
 		LaserLine.enabled= 		true;
 		FlareLight.enabled = 	true;

 		LaserLine.SetPosition(0, LaserRay.origin);

 		while( Input.GetButton("Fire1")){
 			RaycastHit LaserRayHit;
 			if (Physics.Raycast (LaserRay, out LaserRayHit, 1000)) {
 				LaserLine.SetPosition (NumOfVert, LaserRayHit.point);
 				NumOfVert++;
 				print (NumOfVert);
                                         while(LaserRayHit.collider.tag == "MirrorCollider")
 				{
 					//Debug.DrawRay(LaserRayHit.point, LaserRayHit.normal * 10, Color.green);
 					LaserLine.SetVertexCount (NumOfVert);
 					NumOfVert++;
 					Vector3 pos = Vector3.Reflect (LaserRay.direction, LaserRayHit.normal);
 					LaserLine.SetPosition (NumOfVert, pos);
 					LaserRay= new Ray( LaserRayHit.point, LaserRayHit.normal);
 					Physics.Raycast (LaserRay, out LaserRayHit, 1000);
 				}

 				//}
 			}
 			NumOfVert = 1;
 			yield return null;
 		}
                         LaserLine.enabled= false;
 		FlareLight.enabled = false;
 	}

@anuraggoes3d 3 things:

  1. Can you post a picture of the result
  2. You are using 2 obselete functions, try fixing those.
  3. Are the objects that you are reflecting off of unity objects, or are they imported objects. If they are imported, try with a built in unity object, and if it works, its a problem with the normals of your imported object, align its Vectors with the directions in unity, that might fix it.
