使用json存储角色的数据，数据类型

[Serializable]
public class SaveGameData
{
    public CharacterInfo characterInfo;
    public string title;
    [HideInInspector]
    public float savePosX;
    [HideInInspector]
    public float savePosY;
    [HideInInspector]
    public string path;
}

　　

保存游戏数据

 public static void SavePlayerInfo(CharacterInfo characterInfo,Transform transform,string title)
    {
        SaveGameData saveGame = new SaveGameData()
        {
            characterInfo = characterInfo,
            title = saveIndex + "、" + title,
            savePosX = transform.position.x,
            savePosY = transform.position.y,
            path= Application.dataPath + "/Resources/Save/" + saveIndex + ".json"
    };

        string s = JsonConvert.SerializeObject(saveGame);
        using (FileStream fs = new FileStream(saveGame.path, FileMode.OpenorCreate, FileAccess.Write))
        {
            byte[] b = System.Text.Encoding.UTF8.GetBytes(s);
            fs.Write(b,0,b.Length);
        }      
        saveIndex++;

    }

 

读取解析数据

  static SaveGameData ReadJson(string path)
    {
        using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read))
        {
            byte[] data = new byte[fs.Length];
            if (data.Length==0)
                return null;
            fs.Read(data, 0, data.Length);
            byte[] bomBuffer = new byte[] { 0xef, 0xbb, 0xbf };
            string dataStr = System.Text.Encoding.UTF8.GetString(data);
            if (data[0] == bomBuffer[0]
                && data[1] == bomBuffer[1]
                && data[2] == bomBuffer[2])
            {
                int copyLength = data.Length - 3;
                byte[] datanew = new byte[copyLength];
                Buffer.Blockcopy(data, 3, datanew, 0, copyLength);
                dataStr = System.Text.Encoding.UTF8.GetString(datanew);
            }

            return JsonConvert.DeserializeObject<SaveGameData>(dataStr);
        }
    }

　　

    public static void ReadplayerAllInfo()
    {
        string[] paths= Directory.GetFiles(rootPath);
        List<string> validpath = new List<string>();
        for (int i = 0; i < paths.Length; i++)
        {
            if (paths[i].EndsWith(".json"))
            {
                paths[i]=paths[i].Replace("\\", "/");
                validpath.Add(paths[i]);
            }
        }
        m_saveInfo = new List<SaveGameData>();
        saveIndex = validpath.Count+1;
        for (int i = 0; i < validpath.Count; i++)
        {
            Debug.Log(validpath[i]);
            SaveGameData loadplayer = ReadJson(validpath[i]);
            m_saveInfo.Add(loadplayer);
        }
    }

清除保存信息

    internal static void ClearSave(SaveGameData saveInfo)
    {
        m_saveInfo.Remove(saveInfo);
        string file= Path.GetFileName(saveInfo.path);
        string path = rootPath + "/" + file;
        if (File.Exists(path))
        {
            File.Delete(path);
        }
     
        path= rootPath + "/" + file + ".Meta";
        if (File.Exists(path))
        {
            File.Delete(path);
        }
       
    }

　　

暂时没考虑数据加密，后面可能会添加上。
