Deserialize Json into list.,how to deserialize a list via .FromJson

Hi,

I have a problem while deserializing a list, that contains user-type class objects. I successfully serialize the list to a JSON file. However, I cannot load it nor do I get an error. So, here is the PlayerData.cs script that contains player information:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 [System.Serializable]
 public class PlayerData
 {
     public GameObject saveAnnouncer; // This line was added to match the order of variables with CharacterDataTracker.cs.
 
     // Player Data
     public int currentHealth = 3;
     public int maxHealth = 3;
     public int currentCoins = 1;
 
     public List<Gun> equiptedGuns;
 }

Here, you can see DataSaver.cs script file that converts data to JSON and from JSON:

 using UnityEngine;
 using System.IO;
 using System.Runtime.Serialization.Formatters.Binary;
 using System.Collections;
 using System.Collections.Generic;
 
 public static class DataSaver
 {
     private static readonly string SAVE_FOLDER = Application.dataPath + "/Save/";
     
 public static void SavePlayerData(CharacterDataTracker playerData)
     {
         if (!Directory.Exists(SAVE_FOLDER))
         {
             Directory.CreateDirectory(SAVE_FOLDER);
         }
         string jsonString = JsonUtility.ToJson(playerData);
 
         Debug.Log("Saved JSON => " + jsonString); // Referened in the below as '*'
 
         File.WriteAllText(SAVE_FOLDER + "playerData.json", jsonString);
     }
 
     public static PlayerData LoadPlayerData()
     {
         if (!Directory.Exists(SAVE_FOLDER))
         {
             Directory.CreateDirectory(SAVE_FOLDER);
         }
 
         if (File.Exists(SAVE_FOLDER + "playerData.json"))
         {
             string jsonString = File.ReadAllText(SAVE_FOLDER + "playerData.json");
 
             Debug.Log("Loaded JSON => " + jsonString); // Referened in the below as '**'
 
             PlayerData m_playerData = JsonUtility.FromJson<PlayerData>(jsonString);
             if (m_playerData == null)
             {
                 Debug.LogError("The" + m_playerData + "is null. Returning [null].");
                 return null;
             }
             else
             {
                 Debug.Log(m_playerData.currentHealth + "/" + m_playerData.maxHealth + "/" + m_playerData.currentCoins); // Referened in the below as '***'
 
                 foreach (Gun index in m_playerData.equiptedGuns)
                     Debug.Log("The Gun of DataSaver =>" + index); // Referened in the below as '****'
                 
                 return m_playerData;
             }
         }
         return null;
     }
 }

Whenever I save the player data using DataSaver.cs, the Debug.Log(jsonString) (aka '*') prints following log message:

Saved JSON => {"saveAnnouncer":{"instanceID":14614},"currentHealth":95,"maxHealth":100,"currentCoins":22,"equiptedGuns":[{"instanceID":-1514},{"instanceID":-26102},{"instanceID":-26114}]}

So, it is saved into a .json file.

Whenever I try to load from the JSON file using DataSaver.cs, Debug.Log(jsonString) (aka **) prints following log message:

Loaded JSON => {"saveAnnouncer":{"instanceID":14614},"currentHealth":95,"maxHealth":100,"currentCoins":22,"equiptedGuns":[{"instanceID":-1514},{"instanceID":-26102},{"instanceID":-26114}]}

---

According to these two log messages, I'm able to save and load the data into the JsonUtility object. But, if I print the members of the return value of JsonUtility.FromJson(jsonString);, I see following log messages:

95/100/22 (aka '***')

And

The Gun of DataSaver =>Pistol (Gun) (aka '')

The Gun of DataSaver =>

The Gun of DataSaver =>

---

According to the last two log messages, I can convert primitive types but cannot convert the list.

By the way, the Gun class has the following members:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 
 public class Gun : MonoBehaviour
 {
     public static Gun instance;
 
     [Header("Bullets")]
     public GameObject bulletToFire;
     public Transform firePoint;
 
     [Header("Fire System")]
     public float timeBetweenShots;
     private float shotCounter;
 
     [Header("Weapon System")]
     public string weaponName;
     public Sprite gunUI;
 
     [Header("Shop System")]
     public int itemCost;
     public Sprite gunShopSprite;
 
     private void Awake()
     {
         instance = this;
     }
 
     // Start is called before the first frame update
     void Start()
     {
         
     }
 
     // Update is called once per frame
     void Update()
     {
         if (PlayerController.instance.canMove && !LevelManager.instance.isPaused)
         {
             if (shotCounter > 0)
             {
                 shotCounter -= Time.deltaTime;
             }
             else
             {
                 if (Input.GetMouseButtonDown(0) || Input.GetMouseButton(0))
                 {
                     Instantiate(bulletToFire, firePoint.position, firePoint.rotation);
                     shotCounter = timeBetweenShots;
                     AudioManager.instance.PlaySFX(12);
                 }
             }
         }
     }
 }
 

To sum it up, I cannot convert user-type class objects from JSON string into a list, that contains them. I hope I could tell the point where I need help.

Thank you for reading up until this point,

Have a nice night.
