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

 1 using System;
 2 using UnityEngine;
 3 
 4 public class TimeTool {
 5     
 6     public static DateTime GetFutureTime()
 7     {
 8         return DateTime.Today.AddDays(30) ;
 9     }
10 
11     //获取当前
12     public static DateTime GetNowTime()
13     {
14         return DateTime.Today;
15     }
16 
17     public static int GetLeadTime(DateTime d1, DateTime d2)
18     {
19         return (d1 - d2).Days;
20     }
21 
22 }

使用unity自带本地保存数据，PlayerPrefs

1 //记录时间
2 DateTime time = TimeTool.GetFutureTime();
3 
4 //设置时间
5 PlayerPrefs.SetString("CountDownTime", time.ToString());
6 
7 //获取时间
8 PlayerPrefs.GetString("CountDownTime", "");

获得剩余时间，进行倒计时提示

1 string timeStr = PlayerPrefs.GetString("CountDownTime", "");
2 
3 int day = TimeTool.GetLeadTime(Convert.ToDateTime(timeStr), TimeTool.GetNowTime());
4 
5 text = "剩余" + day + "天";
