using UnityEngine;

public class ExampleScript : MonoBehaviour { // Make all rigidbodies we touch fly upwards void OnCollisionStay(Collision collision) { // Check if the collider we hit has a rigidbody // Then apply the force if (collision.rigidbody) { collision.rigidbody.AddForce(Vector3.up * 15); } } }
