Unity日常记录-本地保存未来时间实现倒计时

本地保存未来时间实现倒计时

TimeTool工具类：获取当前时间、未来时间、两时间差

 using System;
 using UnityEngine;

 public class TimeTool {

     public static DateTime GetFutureTime()
     {
         return DateTime.Today.AddDays() ;
     }

     //获取当前
     public static DateTime GetNowTime()
     {
         return DateTime.Today;
     }

     public static int GetLeadTime(DateTime d1, DateTime d2)
     {
         return (d1 - d2).Days;
     }

 }

使用unity自带本地保存数据，PlayerPrefs

 //记录时间
 DateTime time = TimeTool.GetFutureTime();

 //设置时间
 PlayerPrefs.SetString("CountDownTime", time.ToString());

 //获取时间
 PlayerPrefs.GetString("CountDownTime", "");

获得剩余时间，进行倒计时提示

 string timeStr = PlayerPrefs.GetString("CountDownTime", "");

 int day = TimeTool.GetLeadTime(Convert.ToDateTime(timeStr), TimeTool.GetNowTime());

 text = "剩余" + day + "天";
