FLimenReplicatedInventoryItemRegistry

Overview

FLimenReplicatedInventoryItemRegistry is a struct used to store and manage items in a replicated inventory. It includes properties for the item class and instance, as well as callbacks for replication events such as adding, removing, and changing items.

Properties

Type	Name	Access	Description
TSoftClassPtr	ItemClass	Public	The class of the item.
TWeakObjectPtr	ItemInstance	Public	A weak pointer to the instance of the item.

Functions

Return Type	Signature	Description
void	PreReplicatedRemove(const FLimenReplicatedInventoryItemRegistryArray& InArraySerializer)	Called right before deleting an element during replication. Asynchronously handles item retrieval if not on the authority server.
void	PostReplicatedAdd(const FLimenReplicatedInventoryItemRegistryArray& InArraySerializer)	Called after adding and serializing a new element. Asynchronously adds the item to the inventory if not on the authority server.
void	PostReplicatedChange(const FLimenReplicatedInventoryItemRegistryArray& InArraySerializer)	Called after updating an existing element with new data. Asynchronously updates the item in the inventory if not on the authority server.
FString	GetDebugString()	Returns a debug string for logging purposes.

FLimenReplicatedInventoryItemRegistryArray

Overview

FLimenReplicatedInventoryItemRegistryArray is a struct that extends FFastArraySerializer to manage an array of item registries. It includes callbacks for replication events such as adding, removing, and changing items.

Properties

Type	Name	Access	Description
TArray	Items	Public	The array of item registries.
TWeakObjectPtr< ULimenInventoryComponent >	Owner	Public	A weak pointer to the owner component.

Functions

Return Type	Signature	Description
bool	NetDeltaSerialize(FNetDeltaSerializeInfo & DeltaParms)	Serializes changes to the array during replication.
void	PreReplicatedRemove(const TArrayView & RemovedIndices, int32 FinalSize)	Called before removing elements and after the elements themselves are notified. Asynchronously handles slot removals on the game thread.
void	PostReplicatedAdd(const TArrayView & AddedIndices, int32 FinalSize)	Called after adding all new elements and after the elements themselves are notified. Asynchronously handles slot additions on the game thread.
void	PostReplicatedChange(const TArrayView & ChangedIndices, int32 FinalSize)	Called after updating all existing elements with new data and after the elements themselves are notified. Asynchronously handles slot item updates on the game thread.

FLimenReplicatedInventorySlot

Overview

FLimenReplicatedInventorySlot is a struct used to store and manage slots in a replicated inventory. It includes properties for the slot name and item, as well as callbacks for replication events such as adding, removing, and changing items.

Properties

Type	Name	Access	Description
FName	SlotName	Public	The name of the slot.
TScriptInterface< ILimenSlotInventoryItem >	Item	Public	A script interface for the item in the slot.

Functions

Return Type	Signature	Description
void	PreReplicatedRemove(const FLimenReplicatedInventorySlotsArray& InArraySerializer)	Called right before deleting an element during replication.
void	PostReplicatedAdd(const FLimenReplicatedInventorySlotsArray& InArraySerializer)	Called after adding and serializing a new element.
void	PostReplicatedChange(const FLimenReplicatedInventorySlotsArray& InArraySerializer)	Called after updating an existing element with new data.
FString	GetDebugString()	Returns a debug string for logging purposes.
bool	operator==(const FName& InSlotName) const	Equality operator comparing the slot name.
bool	operator==(const FLimenReplicatedInventorySlot& Other) const	Equality operator comparing the slot name and item.
bool	operator==(const TScriptInterface< ILimenSlotInventoryItem >& InItem) const	Equality operator comparing the item in the slot.

Usage & Implementation Notes

The PreReplicatedRemove, PostReplicatedAdd, and PostReplicatedChange functions are designed to handle replication events asynchronously on the game thread.
These structs are used within components like ULimenInventoryComponent and ULimenSlotInventoryComponent to manage inventory data across networked sessions.
