Unity鼠标抓取gameobject(类似碰撞检测)

using UnityEngine;using System.Collections;public class Mouse : MonoBehaviour{    Ray ray;    RaycastHit hit;    void Update()    {        if (Input.GetMouseButton(0))        {            ray = Camera.main.ScreenPointToRay(Input.mousePosition);            if (Physics.Raycast(ray, out hit))                Debug.Log(hit.collider.gameObject.name);        }    }}
