trigger only on collision with player efficiently?

Unity Engine
1

i have an object laying on the ground and it has a tigger so its constantly getting collisions triggers from the terrain collider

so i have this code which works fine

public class ArrowPickupTrigger : MonoBehaviour
{

    private void OnTriggerEnter(Collider other)
    {
        if (!other.gameObject.CompareTag("Player"))
            return;

        GameObject UI = GameObject.Find("UI");
        GameObject pickUpText = Helpers.FindObject(UI, "PickUpText");
        pickUpText.SetActive(true);

       // Debug.Log("ArrowPickupTrigger OnTriggerEnter");
    }

my worry is that its inefficient. i have a feeling that layers are designed to make this more efficient but don’t know how. can someone please advise? thanks

I don’t think it matters as it is minuscule.

But you could make a child object with the trigger on the child object. Then in layers make the child object only interact with the Player in the Physics matrix.

for a handful of arrows it probably is miniscule but its good to know anyhow. i’ll look into layers anyhow, everything is default at the moment
