JsonUtility如何将json打入新行

Question

我一直关注this视频中的教程。

可以在here ...

找到教程源代码

我的问题是我的Json数据全部存储在一行中，

我想将数据分成单行对象数据的新行

这里是Json教程的代码

演员档案

using UnityEngine;
using System.Collections;
using System;

public class Actor : MonoBehaviour {

public ActorData data = new ActorData();

public string name = "Tile";

string newline = "\n";

public void StoreData()
{
    data.name = name;
    data.pos = transform.position;
}

public void LoadData()
{
    name = data.name;
    transform.position = data.pos;

}

public void ApplyData()
{
    SaveData.AddActorData(data);
}

void OnEnable()
{
    SaveData.OnLoaded += LoadData;
    SaveData.OnBeforeSave += StoreData;
    SaveData.OnBeforeSave += ApplyData;

}

void OnDisable()
{
    SaveData.OnLoaded -= LoadData;
    SaveData.OnBeforeSave -= StoreData;
    SaveData.OnBeforeSave -= ApplyData;
}

}

[Serializable]
 public class ActorData
 {
    public string name;
public Vector2 pos;
 }

保存数据文件

 using UnityEngine;
 using System.Collections;
 using System.Xml.Serialization;
 using System.IO;

 public class SaveData
 {

public static ActorContainer actorContainer = new ActorContainer();

public delegate void SerializeAction();
public static event SerializeAction OnLoaded;
public static event SerializeAction OnBeforeSave;

public static void Load(string path)
{
    actorContainer = LoadActors(path);

    foreach (ActorData data in actorContainer.actors)
    {
        GameController.CreateActor(data, GameController.playerPath,
            data.pos, Quaternion.identity);
    }

    OnLoaded();

    ClearActorList();
}

public static void Save(string path, ActorContainer actors)
{
    OnBeforeSave();

    //ClearSave(path);
    SaveActors(path, actors);

    ClearActorList();
}

public static void AddActorData(ActorData data)
{
    actorContainer.actors.Add(data);
}

public static void ClearActorList()
{
    actorContainer.actors.Clear();
}

private static ActorContainer LoadActors(string path)
{
    string json = File.ReadAllText(path);

    return JsonUtility.FromJson<ActorContainer>(json);
}

private static void SaveActors(string path, ActorContainer actors)
{
    string json = JsonUtility.ToJson(actors);

    StreamWriter sw = File.CreateText(path);
    sw.Close();
    File.WriteAllText(path, json);
 }
}

Answer 1

JsonUtility.ToJson函数有两个重载：

• public static string ToJson(object obj);
• public static string ToJson(object obj, bool prettyPrint);

使用第二个并将true传递给它。它将输出格式化为可读性，使json分成几行。

只需将string json = JsonUtility.ToJson(actors);替换为string json = JsonUtility.ToJson(actors, true);

即可

如果您对结果不满意，请对Unity使用Newtonsoft.Json并像这样格式化json：

string json = JsonConvert.SerializeObject(actors);
string newLineJson = JValue.Parse(json).ToString(Formatting.Indented);
