時(shí)間管理類TimerManager.cs
using UnityEngine;
using System;
using System.Collections.Generic;

/// <summary>

時(shí)間對(duì)象類TimerItem.cs

        if (offsetTime >= this.delayTime)
        {

            for (int index = 0; index < count; index++)
            {

啟動(dòng)計(jì)時(shí)管理器UpdateItem.cs
using UnityEngine;

        TimerManager.Run();
    }
}

測(cè)試類Test.cs
using UnityEngine;

public class Test : MonoBehaviour {
    float time = 5f;
        // Use this for initialization
        void Start () {
        TimerManager.Register(this, 1f, () => {
            if (time>0)
            {
                time -= 1f;
                Debug.Log("倒計(jì)時(shí)測(cè)試："+time);
            }
            else
            {
                Debug.Log("倒計(jì)時(shí)結(jié)束");
                TimerManager.UnRegister(this);
            }
