UGameFeatureAction_DataRegistry
is a subclass of UGameFeatureAction
, designed for handling data registries within the Unreal Engine 5 framework. This class focuses on the lifecycle management of data registries associated with game features, including their registration, activation, deactivation, and unregistration.
Functionality
Core Functions
OnGameFeatureRegistering()
: Called when a game feature is being registered. It preloads data registries if required.OnGameFeatureUnregistering()
: Invoked during the unregistering phase of a game feature, handling the temporary disabling of preloaded data registries.OnGameFeatureActivating()
: Executes when a game feature is activated, ensuring data registries are loaded and initialized if not preloaded during registration.OnGameFeatureDeactivating()
: Called when deactivating a game feature, handling the removal of data registries from consideration.
Utility Functions
ShouldPreloadAtRegistration()
: Determines whether data registries should be preloaded during the registration phase, primarily based on the editor context and specific flags.
Editor-Only Functions
AddAdditionalAssetBundleData()
: (Editor-only) Enhances asset bundle data with additional data registry assets.IsDataValid()

Implementation Details
- Utilizes
LOCTEXT_NAMESPACE
for localization support. - Employs conditional compilation with
WITH_EDITOR
andWITH_EDITORONLY_DATA
for editor-specific functionalities. - Implements robust logging and debugging, leveraging
UE_LOG
for logging key actions and conditions. - Includes comprehensive error handling and validation mechanisms, especially within the editor context.
- Compatible with editor mode and handles deprecated include orders (
UE_ENABLE_INCLUDE_ORDER_DEPRECATED_IN_5_2
).
