Question Localization not working in build

I got localization to work in my project, but it doesn't seem to be working whenever I build. I have rebuilt the addressables in multiple ocassions, but in my build everything appears to be resorting to fallback fonts or fallback text. I am currently using this custom class to handle localization in TMPRO components.

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using TMPro;
5. using UnityEngine;
6. using UnityEngine.Localization;
7. using UnityEngine.Localization.Components;
8. using UnityEngine.Localization.Settings;
9. using UnityEngine.ResourceManagement.AsyncOperations;
10.  
11.     public class LocalizeTMProComponent : MonoBehaviour
12.     {
13.         [SerializeField]
14.         LocalizedString stringReference = new LocalizedString();
15.  
16.         public LocalizedString StringReference { get => stringReference; }
17.  
18.         [SerializeField]
19.         LocalizedTMProFont fontAssetReference = new LocalizedTMProFont();
20.  
21.         private TextMeshProUGUI textMeshProUGUI;
22.  
23.         private void Awake()
24.         {
25.             LocalizationSettings.SelectedLocaleChanged += LocaleChanged;
26.             textMeshProUGUI = GetComponent<TextMeshProUGUI>();
27.         }
28.  
29.         IEnumerator Start()
30.         {
31.             // Wait for the Locales to load.
32.             yield return LocalizationSettings.InitializationOperation;
33.         }
34.  
35.         private void OnEnable()
36.         {
37.             LoadString();
38.             LoadFont();
39.         }
40.  
41.         private void LocaleChanged(Locale locale)
42.         {
43.             LoadString();
44.             LoadFont();
45.         }
46.  
47.         private void LoadString()
48.         {
49.             if (!ValidateStringReference()) return;
50.             var operation = stringReference.GetLocalizedStringAsync();
51.             UpdateString(operation);
52.  
53.             textMeshProUGUI.ForceMeshUpdate();
54.         }
55.  
56.         private void LoadFont()
57.         {
58.             if (!ValidateFontAssetReference()) return;
59.             var operation = fontAssetReference.LoadAssetAsync();
60.             UpdateFont(operation);
61.  
62.             textMeshProUGUI.ForceMeshUpdate();
63.         }
64.  
65.         private void UpdateString(AsyncOperationHandle<string> value)
66.         {
67.             if(!value.IsDone)
68.             {
69.                 value.Completed += UpdateString;
70.                 return;
71.             }
72.  
73.             textMeshProUGUI.text = value.Result;
74.         }
75.  
76.         private void UpdateFont(AsyncOperationHandle<TMP_FontAsset> value)
77.         {
78.             if (!value.IsDone)
79.             {
80.                 value.Completed += UpdateFont;
81.                 return;
82.             }
83.  
84.             textMeshProUGUI.font = value.Result;
85.         }
86.  
87.         private bool ValidateStringReference()
88.         {
89.             if (stringReference == null) return false;
90.             return true;
91.         }
92.  
93.         private bool ValidateFontAssetReference()
94.         {
95.             if (fontAssetReference == null) return false;
96.             return true;
97.         }
98.  
99.  
100.     }
101.  
102.  

 

It worked! But now I'm having an issue were if I try to start my game in a different language it shows invalid characters (as if it was translating) and then jumps back to English without changing the font. Do you know why something like this would happen?

 

Both of them, yes

 

Is giving this error

Code (CSharp):

1. Exception: Attempting to use an invalid operation handle
2. UnityEngine.ResourceManagement.AsyncOperations.AsyncOperationHandle`1[TObject].get_InternalOp () (at Library/PackageCache/com.unity.addressables@1.19.19/Runtime/ResourceManager/AsyncOperations/AsyncOperationHandle.cs:213)
3. UnityEngine.ResourceManagement.AsyncOperations.AsyncOperationHandle`1[TObject].get_Result () (at Library/PackageCache/com.unity.addressables@1.19.19/Runtime/ResourceManager/AsyncOperations/AsyncOperationHandle.cs:277)
4. Fiero.Localization.LocalizeTMProComponent+<ChangeText>d__9.MoveNext () (at Assets/Scripts/System/Localization/LocalizeTMProComponent.cs:61)
5. UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at <40205bb2cb25478a9cb0f5e54cf11441>:0)
6.  

 

Is still giving errors even when yielding for the Addressables initialization but if I use the previous LoadFont and LoadText methods it works. The only other detail I have now is that the user is able to see when the language change happens, so I will probably need to add a loading screen or a buffer before the player encounters the first scene

 

I will keep looking into it.
Thanks a lot Karl! Your answers have made my life easier with localization multiple times already and I can't thank you enough
