I have a JSON file that is given as:

{
    "Person": "true",
    "Age": "true",
    "Location": "false",
    "Phone": "true"
}

I am able to read it in Unity by using the code below. I am using SimpleJSON library.

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

public class ReadWriteScene : MonoBehaviour {
    public string jsonFile;
    JSONNode itemsData;
    string path;

    // Start is called before the first frame update
    void Start () {

        path = Path.Combine (Application.streamingAssetsPath, "Settings.json");
        if (File.Exists (path)) {
            jsonFile = File.ReadAllText (path);
            DeserializePages ();
        }
    }

    void Update () {
        
    }

    public void DeserializePages () {
        itemsData = JSON.Parse (jsonFile);
        var parseJSON = JSON.Parse (jsonFile);

        Debug.Log(parseJSON["Phone"].Value);

    }

}

But I do not know how to write or make changes to the JSON via code? For example, how do I change the attribute "Age" to "false"?

It's very easy.

itemsData["Age"] = "false";

Check https://docs.unity3d.com/Packages/[email protected]/api/SimpleJSON.JSONNode.html.

CodePudding user response：

itemsData["Age"] = "false";
File.WriteAllTextAsync(path, itemsData.ToString());

It was quite easy. I used JSONObject and did the following:

public void SaveData(){
        JSONObject json = new JSONObject();
        json.Add("Person", "true");
        json.Add("Age", "false");
        json.Add("Location", "true");
        json.Add("Phone", "true");

        File.WriteAllText(path, json.ToString());
    }

Know that, I did not create a new file, it replaces the already created file but make sure you add all the given attributes or else it will get erased.
