被击中的碰撞器的Rigidbody。如果碰撞器没有附加到 Rigidbody
则为 null
。
using UnityEngine;
public class Example : MonoBehaviour { // Apply a force to a clicked rigidbody object.
// The force applied to an object when hit. float hitForce;
void Update() { if (Input.GetMouseButtonDown(0)) { RaycastHit hit; Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
if (Physics.Raycast(ray, out hit)) { if (hit.rigidbody != null) { hit.rigidbody.AddForce(ray.direction * hitForce); } } } } }
