Question by PeroChield · Apr 30, 2018 at 02:58 PM · uijsonscript error

I don't understand how save to QualitySettings.SetQuality with a json file

I want someone to fix what I've sent and thank you. There is my SettingsManager script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 using System.IO;
 
 public class SettingsManager : MonoBehaviour {
 
     public Dropdown textureQualityDropdown;
     public GameSettings gameSettings;
     public Button applyButton;
 
     void OnEnable()
     {
         textureQualityDropdown.onValueChanged.AddListener(delegate {
 OnTextureQualityDrowpon(); });
         applyButton.onClick.AddListener(delegate { OnApplyButtonClick(); });
         LoadSettings();
     }
     public void OnTextureQualityDrowpon()
     {
         QualitySettings.SetQualityLevel (gameSettings.textureQuality = textureQualityDropdown.value);
     }
     public void OnApplyButtonClick()
     {
         SaveSettings();
     }
     public void SaveSettings()
     {
     public void SaveSettings()
     {
         string jsonData = JsonUtility.ToJson(gameSettings, true);
         File.WriteAllText(Application.persistentDataPath + "/gamesettings.json", jsonData);
     }
  public void LoadSettings()
     {
         File.ReadAllText(Application.persistentDataPath + "/gamesettings.json");
         gameSettings = JsonUtility.FromJson<GameSettings>(File.ReadAllText(Application.persistentDataPath + "/gamesettings.json"));
         textureQualityDropdown.value = gameSettings.textureQuality;
   }
 }

And other is my GameSettings script:

 public class GameSettings{
 
   public int textureQuality;
 
     }

I have another question to ask about how to setup a slider and an input field to takes value ? Thank you for your answers. Because I'm started a Unity program 3 weeks ago.
