计时器

using System.Collections;
using System.Collections.Generic;
using System.Threading;
using UnityEngine;
public class Async : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        //创建定时器
        Timer timer = new Timer(TimeOut, null, 5000, 0);
    }
    // Update is called once per frame
    private void TimeOut(System.Object state)
    {
        Debug.Log("sfas");
    }
}
