Resolved How to add a collider to a line renderer?

I have added a box collider to test whether the collider is present.When I tested the collider is present not the gameobject but behind the gameobject.How to add a collider to line renderer and detect collisions.

 

if you use edgecollider, can set the edgecollider vertices to match linerenderer points

one example

Code (CSharp):

1. if(Input.GetMouseButtonDown(0))
2.         {
3.             Debug.Log("Mouse down");
4.             currenline = Instantiate(linePrefab);
5.             currenline.transform.SetParent(LineParent);
6.             NewLine = currenline.GetComponent<LineRenderer>();
7.  
8.             CurrmousePos0 = Camera.main.ScreenToWorldPoint(Input.mousePosition);
9.             temp0 = new Vector3(CurrmousePos0.x, CurrmousePos0.y, -4);
10.  
11.             NewLine.SetPosition(0, temp0);
12.             NewLine.SetPosition(1, new Vector3(CurrmousePos0.x, CurrmousePos0.y, -4));
13.  
14.  
15.         }
16.         if(Input.GetMouseButtonUp(0))
17.         {
18.  
19.  
20.             CurrmousePos1 = Camera.main.ScreenToWorldPoint(Input.mousePosition);
21.             temp1 = new Vector3(CurrmousePos1.x, CurrmousePos1.y, -4);
22.             NewLine.SetPosition(1, temp1);
23.            
24.             PolygonCollider2D poly=NewLine.gameObject.GetComponent<PolygonCollider2D>();
25.             Vector2[] points = poly.points;
26.  
27.             EdgeCollider2D collider2d = NewLine.gameObject.AddComponent<EdgeCollider2D>();
28.             collider2d.points = points;
29.             Destroy(poly);
30.         }

I tried this code but not working.The collider is as shown above it is behind the gameobject on the origin.Here I added a PolygonCollider2D to the prefab.

 

Any idea how to adjust the z position of collider

 

BoxCollider3D lineCol = gameObject.AddComponent<BoxCollider3D> ();
lineCol.transform.position = line.transform.position;
lineCol.size = new Vector3(5f, 5f,5f);
