The Collider that was hit.
This property is null if the ray hit nothing and not-null if it hit a Collider.
using UnityEngine;
public class Example : MonoBehaviour { void Update() { if (Input.GetMouseButtonDown(0)) { RaycastHit hit; Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
if (Physics.Raycast(ray, out hit)) { if (hit.collider != null) { hit.collider.enabled = false; } } } } }
