Hello,
I’m trying to write a script that get the localized string.
I’m trying to use
UnityEngine.Localization.Settings.LocalizationSettings.StringDatabase.GetLocalizedStringAsync(table, key)
but I don’t know how to wait response and return the string.
Could you help me?
We have examples in the package samples.
The manual has some examples.
There are also examples in the scripting docs.
I would suggest using the LocalizedString class instead of accessing the databases directly.
Yes,
I tried this code
var stringOperation = LocalizationSettings.StringDatabase.GetLocalizedStringAsync("My String", new object[] { 123 });
stringOperation.Completed += s =>
{
// Example output: "The value is 123"
Debug.Log(s.Result);
};
But s.Result is always empty string.
Try passing in the table name before the entry name.
You are using the version that uses the default table so unless you have also configured a default table it wont work.
If its still not working then check that you have a localized value for the current language.
Thanks for your help but nothing works for me.
I’m going crazy 
I think there is a problem with the table loading and also because have to table.
I’ll try to explain.
If the gameobject where I want to load my translations is active when I start the “game” I don’t have any value. I got empty string.
If the gameobject is active later after starting the game it’s ok for my first table named “Localization Table”. But if I tried to get a value into my second table named “StrumPatternTable” I got no translation found for … in StrumPatternTable.
So I think I have two problems :
Here is my entire code where I tried to load a collection within a dropdown :

Yes, your getLocalString method is not waiting for it to complete. I would just use the synchronous methods instead.
Use GetLocalizedString instead of GetLocalizedStringAsync.
Is this script just to localize a Dropdown? You can use the localized property variants to do that.

Thanks I’ll tried.
But first, is there something to call to be sure Localization tables are loaded at start?
By default we dont load all the tables at start, we only load them when they are needed.
You can enable preloading if you want them to be loaded String Tables | Localization | 1.4.5
This will happen during initialization.
You can call LocalizationSettings.InitializationOperation.WaitForCompletion() to force them to be loaded at the start.
Yes I see this documentation on preloading but I don’t have this option.
I have version 1.3.2 of Localization. I think this option have to be there but I don’t have the right part of the windows.
You need to click the metadata icon next to the language name in the table editor window
OK thanks, it seems to work now.
I don’t know what happens before because I do that at first.
Now, I have to reload those values when users change language from the UI. I don’t know how
If you use the LocalizedString.StringChanged event then it will call this when the language changes.
You can also use LocalizationSettings.SelectedLocaleChanged.
oH yes it works
Thank you!
I can now publish my app in english too
