Raycast hit function condition

Unity Engine
1

This is a general question. I have an if statement inside a Physics.Raycast that detects if a “laser switch” has been hit and if so if call for a function.

Method 1:

if (hit.collider.tag == "LaserSwitch")
        {
            hit.transform.GetComponent<LaserSwitch>().LaserRaycastHit();
        }

Method 2:

if (hit.collider.TryGetComponent<LaserSwitch>(out var @switch))
        {
            @switch.LaserRaycastHit();
        }

Since I can’t cache “hit.transform.GetComponent()” since the laser switch may be different every time which method is less expensive or is there a better way to do this?

You’re splitting hairs here. Though I will say that hit.collider.CompareTag("LaserSwitch") is more efficient than hit.collider.tag == "LaserSwitch"

Thanks for the tip! Good to know.
