ALimenBaseHUD

Overview

ALimenBaseHUD is a custom HUD class designed to manage various UI widgets within the game. It inherits from AHUD and provides functionality to show, hide, and update widgets based on player controller and pawn interactions. The class also includes methods for initializing and destroying widgets, as well as handling forced HUD states.

Properties

Type	Name	Access	Description
`uint8`	bAreWidgetsInitialized	Private	A bit flag indicating whether the widgets have been initialized.
`uint8`	bForceHideHud	Private	A bit flag indicating whether the HUD should be forced to hide.
`TArray<TWeakObjectPtr<[ULimenWidget](LimenWidget.md)>>`	WidgetList	Protected	A list of weak pointers to all managed widgets.

Functions

Return Type	Signature	Description
`void`	ShowHUD()	Shows the active widget if it is valid.
`void`	HideHUD()	Hides the active widget if it is valid.
`void`	ForceHUDState(const bool bForce)	Sets the forced HUD state.
`bool`	GetForcedHudState() const	Returns the current forced HUD state.
`void`	ShowActiveWidget()	Shows the currently active widget.
`void`	HideActiveWidget()	Hides the currently active widget.
`ULimenWidget*`	GetActiveWidget() const	Returns a pointer to the currently active widget.
`TArray<TWeakObjectPtr<[ULimenWidget](LimenWidget.md)>>`	GetWidgetList() const	Returns an array of weak pointers to all managed widgets.
`void`	EndPlay(const EEndPlayReason::Type EndPlayReason)	Cleans up and destroys all widgets when the HUD is destroyed.
`void`	DestroyWidgets()	Placeholder for destroying all widgets. Currently does nothing.
`void`	InitializeWidgets()	Placeholder for initializing all widgets. Currently does nothing.
`void`	HudInitialized(APlayerController* PlayerController)	Called after the HUD has been initialized with a player controller.
`void`	UpdateWidgets(APlayerController* PlayerController, APawn* Pawn)	Updates the state of the HUD based on the player controller and pawn.
`bool`	CanSwitchWidgetVisibility(UWidget* InWidget) const	Determines if a widget can be shown or hidden based on the forced HUD state.
`void`	ShowWidget_Internal(ULimenWidget* Widget)	Internal method to show a widget, ensuring it is valid and not already showing.
`void`	HideWidget_Internal(ULimenWidget* Widget)	Internal method to hide a widget, ensuring it is valid and currently showing.
`void`	AddWidgetToList(ULimenWidget* InWidget)	Adds a widget to the internal list of managed widgets.
`void`	RemoveWidgetFormList(ULimenWidget* InWidget)	Removes a widget from the internal list of managed widgets.

Usage & Implementation Notes

Threading Constraints: This class is designed to be used within the Unreal Engine's game thread.
Replication Requirements: None.
Memory Lifetime Management: Widgets are managed using weak pointers, ensuring that they can be safely destroyed without causing memory leaks.
Initialization Dependencies: The UpdateWidgets method should be called with a valid player controller and pawn to properly initialize the HUD.
