The rigidbody that was hit by the controller.
Null if we didn't touch a rigidbody but a static collider.
using UnityEngine;
public class Example : MonoBehaviour { // Activate the gravity of other object we touch void OnControllerColliderHit(ControllerColliderHit hit) { if (hit != null) { hit.rigidbody.useGravity = true; } } }
