Alterar as qualidades das sombras com um dropdown

Bom vou explicar rapidamente e espero que alguém me responda...

tenho isto em meu script:

Código:

public Dropdown ShadowQualityDropdown;

ShadowQualityDropdown.onValueChanged.AddListener (delegate {Shadow();});
   
public void Shadow(){
      QualitySettings.shadows = gameSettings.ShadowQuality = ShadowQualityDropdown.value;
   }

e tenho outro script que guarda as infos em um arquivo .json para carregar depois:
(Ele e um script limpo que não importa nada nem deriva do MonoBehaviour)

Código:

public int ShadowQuality;

eu queria saber como que quando eu alterar na dropdown que esta sendo controlada pelo script 1 ele altere no QualitySettings

se alguem quiser os 2 scripts completos para ver melhor oq eu posso fazer ta ai:

Código:

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

public class SettingsManager : MonoBehaviour {
   public Toggle FullScreenToggle;
   public Dropdown ResolutionDropDown;
   public Dropdown QualityDropDown;
   public Dropdown AADropDown;
   public Dropdown ShadowQualityDropdown;
   public Dropdown vSyncDropDown;
   public Slider MusicVolume;
   public Slider SFXVolume;
   public Slider WeatherVolume;
   public AudioSource MusicSource;
   public AudioSource SFXSource;
   public AudioSource WeatherSource;
   public string[] QualityLevels;
   public Button ApplyButton;

   public Resolution[] resolutions;
   public GameSettings gameSettings;

   void OnEnable(){
      resolutions = Screen.resolutions;
      gameSettings = new GameSettings();
      FullScreenToggle.onValueChanged.AddListener (delegate {OnFullScreenToggle();});
      ResolutionDropDown.onValueChanged.AddListener (delegate {OnResolutionChange();});
      QualityDropDown.onValueChanged.AddListener (delegate {OnQualityChange();});
      AADropDown.onValueChanged.AddListener (delegate {OnAAChange();});
      vSyncDropDown.onValueChanged.AddListener (delegate {OnVsyncChange();});
      MusicVolume.onValueChanged.AddListener (delegate {OnMusicChange();});
      SFXVolume.onValueChanged.AddListener (delegate {OnSFXChange();});
      WeatherVolume.onValueChanged.AddListener (delegate {OnWeatherVolChange();});
      ApplyButton.onClick.AddListener (delegate {OnSaveButton();});
      ShadowQualityDropdown.onValueChanged.AddListener (delegate {Shadow();});

      resolutions = Screen.resolutions;

      foreach (Resolution resolution in resolutions) {
         ResolutionDropDown.options.Add (new Dropdown.OptionData (resolution.ToString ()));
      }

   }
   public void OnFullScreenToggle(){
      gameSettings.FullScreen = Screen.fullScreen = FullScreenToggle.isOn;
   }
   public void OnResolutionChange(){
      Screen.SetResolution (resolutions [ResolutionDropDown.value].width, resolutions [ResolutionDropDown.value].height, Screen.fullScreen);
   }
   public void OnQualityChange(){
      QualitySettings.masterTextureLimit = gameSettings.Quality = QualityDropDown.value;

   }
   public void OnVsyncChange(){
      QualitySettings.vSyncCount = gameSettings.vSync = vSyncDropDown.value;
   }
   public void OnAAChange(){
      QualitySettings.antiAliasing = gameSettings.AntiAliasing = (int)Mathf.Pow (2, AADropDown.value);
   }
   public void OnMusicChange(){
      MusicSource.volume = gameSettings.MusicVolume = MusicVolume.value;
   }
   public void OnSFXChange(){
      SFXSource.volume = gameSettings.SxfVolume = SFXVolume.value;
   }
   public void OnWeatherVolChange(){
      WeatherSource.volume = gameSettings.WeatherVolume = WeatherVolume.value;
   }
   public void SaveSett(){
      string JsonData = JsonUtility.ToJson (gameSettings, true);
      File.WriteAllText (Application.persistentDataPath + "/gamesettings.json", JsonData);

   }
   public void OnSaveButton(){
      SaveSett ();
   }
   public void Shadow(){
      QualitySettings.shadows = gameSettings.ShadowQuality = (int)Mathf.Pow (1, ShadowQualityDropdown.value);
   }

}


Código:


public class GameSettings {

   public bool FullScreen;
   public int Quality;
   public int AntiAliasing;
   public int vSync;
   public int ResolutionIndex;
   public float MusicVolume;
   public float SxfVolume;
   public float WeatherVolume;
   public int ShadowQuality;

}


Apenas coloque um método no OnValueChanged do Dropdown pelo inspector e passar a função para mudar a resolução!
