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(30) ;
    }

    //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";
