我一直在为我的项目开发保存游戏解决方案,但遇到了困难。经过几天的研究、试验/错误等,我决定试一试堆栈。我正在尝试将 Json 文本文件转换回对象,然后将其添加到字典中。无论我如何遍历 Jdata 对象,它都会不断地给出我的无效强制转换异常。请记住,我正在使用 LitJson 3rd 方。这是到目前为止的代码。错误发生在 foreach 语句中。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using LitJson;
using System.IO;
public static class SaveGame {
public static string savePath = Application.persistentDataPath +
"/Saves/";
public static int numberOfSaves = 0;
public static string saveFileName = PlayerCrew.playerShipName + ".json";
public static void SavePlayerData ()
{
string playerSavePath = savePath + saveFileName;
string jsonHolder;
jsonHolder = JsonMapper.ToJson(PlayerCrew.playerCrewManifest);
if (!File.Exists(playerSavePath))
{
FileStream fs = new FileStream(playerSavePath,
FileMode.OpenOrCreate);
fs.Close();
File.WriteAllText(playerSavePath, jsonHolder);
}
else
{
File.WriteAllText(playerSavePath, jsonHolder);
}
}
public static void LoadCrewManifest()
{
string playerSavePath = savePath + saveFileName;
string jsonHolder;
jsonHolder = File.ReadAllText(playerSavePath);
JsonData jdata = JsonMapper.ToObject(jsonHolder);
PlayerCrew.playerCrewManifest.Clear();
foreach (KeyValuePair<string,CrewMember> item in jdata)
{
PlayerCrew.playerCrewManifest.Add(item.Key, item.Value);
Debug.Log(item.Key);
}
}
}
