Im using Unity and developing a game,which when a laser hit the object with the tag "gems" and it will be destroyed.Here's my code:

```

//Handle ray reflection

Ray ray = new Ray(position, direction);

            RaycastHit hit;

            if (Physics.Raycast(ray, out hit, laserMaxLength, reflectionMask))

            {

                Vector3 reflectDirection = Vector3.Reflect(direction, hit.normal);

                lineRenderer.positionCount = ++pointCount;

                lineRenderer.SetPosition(pointCount - 1, hit.point);

                position = hit.point;

                direction = reflectDirection;

                Check(hit.collider.gameObject);

            }

            else

            {

                lineRenderer.positionCount = ++pointCount;

                lineRenderer.SetPosition(pointCount - 1, position + direction * laserMaxLength);

                break;

            }

//Handle Collision with Gems

            if (Physics.Raycast(ray, out hit)) {

                if(hit.collider.gameObject.tag=="gems"){

               Destroy(hit.collider.gameObject);

                }

              }

```

however it is not working!my gem contains a mesh collider with Convex set to true only.

Pls help!
