Saving SelectedLocale with PlayerPrefs

Hello!

I'm new to programming, and I'm stuck with saving the chosen language.

I'm using the Localization Package. And I'd like to save the preferable language using PlayerPrefs.

I've found a script for changing the language within the game via dropdown, and I started adding PlayerPrefs. But when I'm trying to retrieve the value in another script, I have an error "CS0029: Cannot implicitly convert type "int" to "UnityEngine.Localization.Locale"."

How can I save the language preference properly?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Localization.Settings;
5. using TMPro;
6.  
7. public class LocaleDropdown : MonoBehaviour
8. {
9.     public TMP_Dropdown dropdown;
10.  
11.  
12.     IEnumerator Start()
13.     {
14.         // Wait for the localization system to initialize, loading Locales, preloading etc.
15.         yield return LocalizationSettings.InitializationOperation;
16.  
17.         // Generate list of available Locales
18.         var options = new List<TMP_Dropdown.OptionData>();
19.         int selected = 0;
20.         for (int i = 0; i < LocalizationSettings.AvailableLocales.Locales.Count; ++i)
21.         {
22.             var locale = LocalizationSettings.AvailableLocales.Locales[i];
23.             if (LocalizationSettings.SelectedLocale == locale)
24.                 selected = i;
25.             options.Add(new TMP_Dropdown.OptionData(locale.name));
26.            
27.            
28.         }
29.         dropdown.options = options;
30.      
31.  
32.         dropdown.value = selected;
33.         dropdown.onValueChanged.AddListener(LocaleSelected);
34.     }
35.  
36.     public static void LocaleSelected(int index)
37.     {
38.         LocalizationSettings.SelectedLocale = LocalizationSettings.AvailableLocales.Locales[index];
39.         PlayerPrefs.SetInt("language", index);
40.         PlayerPrefs.Save();
41.         Debug.Log(PlayerPrefs.GetInt("language") + "Language Saved!");
42.     }
43. }

and the second script

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Localization.Settings;
3.  
4. public class LocalizationManager : MonoBehaviour
5. {
6.     void Awake()
7.     {
8.         if (PlayerPrefs.HasKey("language"))
9.         {
10.             LocalizationSettings.SelectedLocale = PlayerPrefs.GetInt("language");
11.         }
12.         else if (Application.systemLanguage == SystemLanguage.Russian)
13.         {
14.             PlayerPrefs.SetInt("language", 1);
15.         }
16.         else
17.         {
18.             PlayerPrefs.SetInt("language", 0);
19.         }
20.     }
21. }

 

Thank you!
Could you please point out how to add it? I have a 2021.1 Unity version and there's no playerprefs, although I saw screenshots with a Player Preference Key

My version


Found screenshot

 

How do you save that player pref?

Like this?

PlayerPrefs.SetString("selected-locale", LocalizationSettings.SelectedLocale.LocaleName);

My other question is, how do you load it? or will it be automatically loaded?

I'm new using this package, thank you in advance

 

Yes, I'm using that in the fuction "OnSelectionChanged", but once I run the game again, it doesn't change to my last selected local

Code (CSharp):

1. using System.Collections.Generic;
2. using UnityEngine.Localization.Settings;
3. using UnityEngine.ResourceManagement.AsyncOperations;
4. using TMPro;
5. namespace UnityEngine.Localization.Samples
6. {
7.     public class LanguageSelectionMenuUGUIDropdown : MonoBehaviour
8.     {
9.        
10.         public TMP_Dropdown m_Dropdown;
11.         AsyncOperationHandle m_InitializeOperation;
12.  
13.         void Start()
14.         {
15.             // First we setup the dropdown component.
16.             m_Dropdown = GetComponent<TMP_Dropdown>();
17.             m_Dropdown.onValueChanged.AddListener(OnSelectionChanged);
18.  
19.             // Clear the options an add a loading message while we wait for the localization system to initialize.
20.             m_Dropdown.ClearOptions();
21.             m_Dropdown.options.Add(new TMP_Dropdown.OptionData("Loading..."));
22.             m_Dropdown.interactable = false;
23.  
24.             // SelectedLocaleAsync will ensure that the locales have been initialized and a locale has been selected.
25.             m_InitializeOperation = LocalizationSettings.SelectedLocaleAsync;
26.  
27.             if (m_InitializeOperation.IsDone)
28.             {
29.                 InitializeCompleted(m_InitializeOperation);
30.             }
31.             else
32.             {
33.                 m_InitializeOperation.Completed += InitializeCompleted;
34.             }
35.         }
36.  
37.         void InitializeCompleted(AsyncOperationHandle obj)
38.         {
39.             // Create an option in the dropdown for each Locale
40.             var options = new List<string>();
41.  
42.             int selectedOption = 0;
43.  
44.             var locales = LocalizationSettings.AvailableLocales.Locales;
45.  
46.             for (int i = 0; i < locales.Count; ++i)
47.             {
48.                 var locale = locales[i];
49.  
50.                 if (LocalizationSettings.SelectedLocale == locale)
51.                     selectedOption = i;
52.  
53.                 var displayName = locales[i].Identifier.CultureInfo != null ? locales[i].Identifier.CultureInfo.NativeName : locales[i].ToString();
54.              
55.                 options.Add(displayName);
56.             }
57.  
58.             // If we have no Locales then something may have gone wrong.
59.             if (options.Count == 0)
60.             {
61.                 options.Add("No Locales Available");
62.  
63.                 m_Dropdown.interactable = false;
64.             }
65.             else
66.             {
67.                 m_Dropdown.interactable = true;
68.             }
69.  
70.             m_Dropdown.ClearOptions();
71.  
72.             m_Dropdown.AddOptions(options);
73.  
74.             m_Dropdown.SetValueWithoutNotify(selectedOption);
75.  
76.             LocalizationSettings.SelectedLocaleChanged += LocalizationSettings_SelectedLocaleChanged;    
77.         }
78.  
79.         void OnSelectionChanged(int index)
80.         {
81.             // Unsubscribe from SelectedLocaleChanged so we don't get an unnecessary callback from the change we are about to make.
82.             LocalizationSettings.SelectedLocaleChanged -= LocalizationSettings_SelectedLocaleChanged;
83.  
84.             var locale = LocalizationSettings.AvailableLocales.Locales[index];
85.  
86.             Debug.Log("current Selected local " + LocalizationSettings.SelectedLocale.LocaleName);
87.  
88.             //Here I'm using it
89.             LocalizationSettings.SelectedLocale = locale;
90.  
91.             Debug.Log("new Selected local "+ LocalizationSettings.SelectedLocale.LocaleName);
92.  
93.             // Resubscribe to SelectedLocaleChanged so that we can stay in sync with changes that may be made by other scripts.
94.             LocalizationSettings.SelectedLocaleChanged += LocalizationSettings_SelectedLocaleChanged;
95.         }
96.  
97.         void LocalizationSettings_SelectedLocaleChanged(Locale locale)
98.         {
99.             // We need to update the dropdown selection to match.
100.             var selectedIndex = LocalizationSettings.AvailableLocales.Locales.IndexOf(locale);
101.  
102.             m_Dropdown.SetValueWithoutNotify(selectedIndex);
103.         }
104.     }
105. }
106.  

 

Is this how it's supposed to be?

 

Yes, there was another script causing a conflict, now it works, thanks!

 

Excuse me, how can I save the state on localization when changing scene?

 

I'm trying to save the state of the setting of the user where the user selected a preferred language, but I don't know how to save it. When I'm changing the scene the selected language is resetting to the default language.

 

Can I ask how to set the playerpref for localizationSettings.SelectedLocale?

 

So it will no more needed for the c# script? it just automatically save the selected language? There's no need for code when the user click language? Sorry for having too many questions? I'm new in using Unity hehe

 

How I'm going to set this if I want this to apply to other scenes? It keeps on going back to default

 

Hey, man. Thanks, it works. It is changing the language when the user selected a language, it save the the selected language. But there is still a little thing to fix when changing the scene. It doesn't changing the text.

 

Oh, I haven't read that. I'm going to read it now. In order to change the text in other scenes, do I need to follow all of this in the manual? Or just choose one of this guides?

 

I folow the instructions but I have encountered an error. How can I fix this?
