GetLocalizedString(TableEntryReference, IList<Object>, Locale, FallbackBehavior)

Attempts to retrieve a string from the requested table. Uses WaitForCompletion to force the loading to complete synchronously. Please note that WaitForCompletion is not supported on WebGL.

Declaration
public string GetLocalizedString(TableEntryReference tableEntryReference, IList<object> arguments, Locale locale = null, FallbackBehavior fallbackBehavior = FallbackBehavior.UseProjectSettings)
Parameters
Type Name Description

A reference to the entry in the StringTable
IList<Object> arguments

Arguments passed to SmartFormat or String.Format.
Locale locale

The Locale to use instead of the default SelectedLocale
FallbackBehavior fallbackBehavior

A Enum which determines if a Fallback should be used when no value could be found for the Locale.
Returns
Type Description
String
Examples

This example shows how to get a localized string from the DefaultTable which uses formatting arguments and use the Completed event to display it.

    // Example string: "The value is {0}"
    var stringOperation = LocalizationSettings.StringDatabase.GetLocalizedStringAsync("My String", new object[] { 123 });
    stringOperation.Completed += s =>
    {
        // Example output: "The value is 123"
        Debug.Log(s.Result);
    };

GetLocalizedStringAsync(TableEntryReference, IList<Object>, Locale, FallbackBehavior)

Attempts to retrieve a string from the requested table. This method is asynchronous and may not have an immediate result. Check IsDone to see if the data is available, if it is false then you can use the Completed event to get a callback when it is finished, yield on the operation or call WaitForCompletion to force the operation to complete.

    // We can force the operation to complete.
    if (!stringOperation.IsDone)
        stringOperation.WaitForCompletion();

    Debug.Log(stringOperation.Result);

This example shows how to get a localized string from the DefaultTable of a custom locale (not the currently selected locale) and use a coroutine to wait for it to complete.

    // We can skip waiting if the operation is already done.
    if (!stringOperation.IsDone)
