Text Functions

The UUDCoreTextFunctionLibrary provides utilities for working with Unreal's FText type.

FText is Unreal Engine's localization-friendly text type. Use it for any user-facing text that may need translation.

Validation Functions

IsNotEmpty

Checks if an FText value contains any content (is not empty).

This is the inverse of the built-in IsEmpty function, provided for cleaner Blueprint logic.

Search for "Is Not Empty" (under Text category) in the Blueprint action menu.

FText TextToCheck = FText::FromString(TEXT("Hello"));
bool bHasContent = UUDCoreTextFunctionLibrary::IsNotEmpty(TextToCheck);
// Result: true

FText EmptyText = FText::GetEmpty();
bool bIsEmpty = UUDCoreTextFunctionLibrary::IsNotEmpty(EmptyText);
// Result: false

Parameters

Name	Type	Description
`Text`	`FText`	The text to check

Returns

Name	Type	Description
`ReturnValue`	`bool`	`true` if the text is not empty

Use Cases

Input Validation

// Validate that user entered something
FText UserInput = GetUserInput();
if (UUDCoreTextFunctionLibrary::IsNotEmpty(UserInput))
{
    // Process the input
    ProcessInput(UserInput);
}
else
{
    // Show error message
    ShowError(TEXT("Please enter a value"));
}

Conditional Display

In Blueprints, you can use this to conditionally show UI elements:

Get your FText value
Call Is Not Empty
Branch based on the result
Show/hide UI elements accordingly
