Download Contents Update Workflow

I would like to update my localized download contents without leaving the app running.
I think the following steps are needed to do this.

1. Unload target tables
2. Update the Addressables Catalog
3. Re-initialize Localization
4. Load the tables again

I have been able to test that the contents can be updated using the following script, but I am not confident that this is correct. In particular, the part that resets and reinitializes LocalizationSettings.

What is the correct way to update the download contents by Localization?

Code (CSharp):

1. using System.Collections;
2. using UnityEngine;
3. using UnityEngine.AddressableAssets;
4. using UnityEngine.Localization.Settings;
5. using UnityEngine.UI;
6.  
7. namespace LocalizationTest
8. {
9.     public class LocalizationContentsUpdateTest : MonoBehaviour
10.     {
11.         [SerializeField] private Button _button;
12.         [SerializeField] private Text _text;
13.         [SerializeField] private string _stringTableName = "ExampleStringTable";
14.         [SerializeField] private string _stringEntryName = "ExampleStringEntry";
15.  
16.         public void Awake()
17.         {
18.             _button.onClick.AddListener(OnClicked);
19.         }
20.  
21.         public void OnDestroy()
22.         {
23.             _button.onClick.RemoveListener(OnClicked);
24.         }
25.  
26.         private void OnClicked()
27.         {
28.             LogEntryValue();
29.         }
30.  
31.         private void LogEntryValue()
32.         {
33.             StartCoroutine(LogEntryValueRoutine());
34.         }
35.  
36.         private IEnumerator LogEntryValueRoutine()
37.         {
38.             // Update catalog.
39.             var checkUpdatesHandle = Addressables.CheckForCatalogUpdates(false);
40.             yield return checkUpdatesHandle;
41.             var updates = checkUpdatesHandle.Result;
42.             Addressables.Release(checkUpdatesHandle);
43.             if (updates.Count >= 1)
44.                 Addressables.UpdateCatalogs();
45.  
46.             // Reset initialization state.
47.             LocalizationSettings.Instance.ResetState();
48.            
49.             // Initialize LocalizationSettings.
50.             yield return LocalizationSettings.InitializationOperation;
51.  
52.             // Load table.
53.             var handle = LocalizationSettings.StringDatabase.PreloadTables(_stringTableName);
54.             yield return handle;
55.  
56.             // Get entry.
57.             var entry = LocalizationSettings.StringDatabase.GetTableEntry(_stringTableName, _stringEntryName).Entry;
58.  
59.             if (_text != null)
60.                 _text.text = entry.Value;
61.  
62.             // Release table.
63.             LocalizationSettings.StringDatabase.ReleaseTable(_stringTableName);
64.         }
65.     }
66. }
67.  

Thanks!

 

Thanks for the immediate response.

> You need to make sure the tables are actually unloaded though.
Yes, I understand. Thank you!

That sounds so good!
