如何存盤DateTime資料并在以后計算？統一C#

我是一個初學者，我正在嘗試用花制作一個經典的 Tamagotchi 游戲，你需要每天給它澆一次水。我使用“澆花”按鈕作為主要功能。為此，我需要知道最后一次單擊以將其與當前時間進行比較是什么時候。

我很努力地嘗試使用PlayerPrefsandDateTime方法，但問題出在這里——DateTime使用 long 和PlayerPrefs使用intor strings。我找到了轉換DateTime為二進制然后轉換為字串的解決方案，但 Unity 告訴我這件事：

FormatException：輸入字串的格式不正確。System.Number.StringToNumber (System.String str, System.Globalization.NumberStyles options, System.Number NumberBuffer& number, System.Globalization.NumberFormatInfo info, System.Boolean parseDecimal) (at <695d1cc93cca45069c528c15c9fdd749>:0) System.Number.ParseInt64 (System.String value, System.Globalization.NumberStyles options, System.Globalization.NumberFormatInfo numfmt) (at <695d1cc93cca45069c528c15c9fdd749>:0) System.Int64.Parse (System.String s, System.IFormatProvider provider) (at <695d1cc93cca45069c528c15c9fdd749>: 0) System.Convert.ToInt64 (System.String 值) (在 <695d1cc93cca45069c528c15c9fdd749>:0) HealthScript.Update () (在 Assets/Scripts/HealthScript.cs:42)

這是整個代碼：

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class HealthScript : MonoBehaviour
{
    public int health = 100;
    public Slider slider;
    public int damage;
    public int waterTime;
    public bool isGoing = true;
    DateTime currentTime = DateTime.UtcNow;
    DateTime lastTimeClicked;

    //reseting the health every time button is clicked and saving the time of it
    public void buttonClicked()
    {
        health = 100;
        PlayerPrefs.SetString("Last Time Clicked", DateTime.UtcNow.ToBinary().ToString());
    }

    public void Update()
    {
        //connecting the health to the slider
        slider.value = health;
        //quit of the game
        if (Input.GetKey(KeyCode.Escape))
        {
            Application.Quit();
        }

        //calculating the difference between last click and actual time
        long temp = Convert.ToInt64(PlayerPrefs.GetString("Last Time Clicked"));
        lastTimeClicked = DateTime.FromBinary(temp);
        print("LastTimeClicked"   lastTimeClicked);

        TimeSpan difference = currentTime.Subtract(lastTimeClicked);
        print("Difference: "   difference);
    }
}

現在，我只是想解決這個問題，以便繼續做其他事情。您能否建議控制臺日志的解決方案，或者是實作我目標的更好方法？

如果您更改存盤和檢索DateTime邏輯的其余部分的方式應該沒問題。試試這個：

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class HealthScript : MonoBehaviour
{
    public int health = 100;
    public Slider slider;
    public int damage;
    public int waterTime;
    public bool isGoing = true;
    DateTime currentTime = DateTime.UtcNow;
    DateTime lastTimeClicked;

    //reseting the health every time button is clicked and saving the time of it
    public void buttonClicked()
    {
        health = 100;
        PlayerPrefs.SetString("Last Time Clicked", DateTime.UtcNow.ToString()); // you can add a formatter here if you want
    }

    public void Update()
    {
        //connecting the health to the slider
        slider.value = health;
        //quit of the game
        if (Input.GetKey(KeyCode.Escape))
        {
            Application.Quit();
        }

        //calculating the difference between last click and actual time
        lastTimeClicked = DateTime.Parse(PlayerPrefs.GetString("Last Time Clicked"));
        print("LastTimeClicked"   lastTimeClicked);

        TimeSpan difference = currentTime.Subtract(lastTimeClicked);
        print("Difference: "   difference);
    }
}

如果要登錄到控制臺，命令為Debug.Log、Debug.LogWarning或Debug.LogError。

您需要確保您的控制臺過濾器也設定為顯示您要列印的任何內容：
