FText::FindTextInLiveTable_Advanced

function Core Since unknown

#include "Internationalization/Text.h"

Access: public Specifiers: static

Description

Looks up a localized FText entry directly from the live (runtime) localization table by namespace and key, bypassing the normal LOCTEXT macro caching.

Caveats & Gotchas

• Returns false if the namespace/key combination is not present in the currently loaded localization data — always check the return value and handle missing text gracefully rather than assuming a match.
• The _Advanced suffix signals that this is a low-level API. Prefer LOCTEXT() or NSLOCTEXT() macros in almost all gameplay and UI code; use this function only when you need runtime key/namespace lookups (e.g. data-driven localization pipelines).

Parameters

Name	Type	Description	Default
Namespace	const FTextKey&	The localization namespace to search within.	—
Key	const FTextKey&	The localization key to look up.	—

Return Type

bool

Example

Runtime lookup of a localized string by key C++

FText FoundText;
bool bFound = FText::FindTextInLiveTable_Advanced(
    FTextKey(TEXT("MyNamespace")),
    FTextKey(TEXT("MyKey")),
    FoundText);
if (bFound)
{
    UE_LOG(LogTemp, Log, TEXT("Found: %s"), *FoundText.ToString());
}
