Changelog

[added] Dedicated (optional) Loot Handler that can handle received loot on client and server. [added] Dynamic Attributes will support level-based curve tables to update their values. [added] Dynamic Attribute ViewModel to be used in conjunction with the equivalent List version.

[added] Item prerequisites that can be applied when the item is being added to the inventory or an equipment state is being set. [added] Support for Customizable Objects (Mutable) for Equipment State Representations. [added] Preliminary checks for pickups, before adding them to inventories. Includes stack change and synchronization for pickup quantities. [added] Introduced a new specialized base widget for grid-based containers. [added] Offhand placement fragment including a fast-access cache in the Equipment Manager. [added] Loot persistency policies used by loot generation (none, requester, source). [improvement] Removed timer from Equipment Manager used to wait for a controller. Added broadcasts for avatars and owners to the Inventory Subsystem. [improvement] Helper function to move equipment items between storage and equipment containers (i.e. "right click equip"). [improvement] Introduced an option to create a brush based on the icon, for the User Interface ViewModel. [improvement] Promoted spatial layouts and linked containers from experimental to beta. [improvement] Consumable fragment is more deliberate about its use mode, supporting unlimited and single use directly. [fix] Get Inventory from the Function Library will be able to navigate Pawn/Player States/Controllers for inventory search. [fix] Ensured that items with equipment without a presence for their initial state are always initialized. [fix] Ensured that the item is removed from the inventory when the last item stack is consumed.

[added] Key fragment with accompanying unlock operation class. [improvement] Removed the order requirement for container and equipment fragments. [improvement] Equipment Manager is compatible with inventory avatar changes during gameplay. [build] Added support to Unreal Engine 5.7, removed Unreal Engine 5.4 support

[added] "InventoryInitializationWatcherInterface" to track final inventory states on an owner or avatar. [added] "EquipmentAnimationInterface" allows Equipment Animation Blueprints to receive the equipment and avatar. [improvement] Consolidated interface names to be categorized in a better hierarchy. [fix] Ensure that presence is updated when state changes, so sockets are updated. [fix] Ensure that all active equipment presences are removed when equipment manager ends play.

[added] Encumbrance Gameplay Effect for convenience. [improvement] Gameplay Effect fragment can interact with the Stack fragment. [improvement] Ensure the Weight fragment always synchronizes with new stack sizes. [improvement] Clean-up the Wealth Gameplay Effect, so it can be properly extended. [improvement] Gameplay Debugger also allows displaying item IDs. [improvement] Reviewed equipment state callback functions to avoid potential race conditions. [fix] Replication for Dynamic Attributes is kept during inventory transfers. [fix] Items fully merged will be deleted instead of dropped. [fix] The drag and drop operation will correctly trigger a swap for items of same type, when the target item has a full stack. [fix] Ensured that swap logic will always sanitize position types and prioritize swapped items before finding alternative positions.

[added] ViewModel exposing Inventory Attributes, such as Encumbrance and Wealth. [improvement] Modified Equipment Load callback to make it more robust for precompiled libraries plus deep hierarchies. [fix] Send Inventory Event notify won't trigger ensure assertion on editor. [fix] Added platform allowlist for the test module. [fix] Ensured that dynamic magnitudes are always applied, regardless of a previous application that happened before. [fix] Changed direct call to interface call in NinjaInventoryDropZoneWidget.

[improvement] Marked container function GetTotalSlots as virtual. [improvement] Added an option to still execute item actions, even when an ability animation is missing. [improvement] The inventory Subsystem will support registering inventories using either the avatar or owner. [improvement] Added a GetInventoryAnimInstance function in the Equipment Interface, to support realtime retargeting scenarios. [fix] Ensured that the equipment manager queries equipment instances, not items. [fix] Reintroduced missing blueprint attributes for inventory item, equipment and components. [fix] Corrected the logic to determine the attach socket for the equipment actor, so it correctly addresses optional overrides.

[added] Introduced a network proxy and authorized inventory checkers. [improvement] Exposed dedicated transfer function for inventory items. [improvement] Updated arrays with raw object pointers to use TObjectPtr instead. [improvement] Simplified the ASC binding flow to remove the confusing "bShouldFailFromASC" flag. [improvement] Modified fragment initialization signature to avoid unnecessary copying of the initial memory struct. [improvement] Automatic server RPC management for item and container functions. [improvement] Tag-based visibility for Equipment Actors. [fix] Build issue from FInventoryItemContainerPlacementOperation. [fix] Corrected the description to match the purpose of the Drag and Drop ViewModel. [fix] Added missing call to "Super" in the Inventory View Model resolver.

[major] Moved all inventory and fragment delegates to the Inventory Manager. [major] Updated Blueprint APIs to use FInstancedStruct (replaces TInstancedStruct in select signatures). [major] Converted mostly the entire UI to View Models + Inventory Resolver. [major] Container Placement: memory-driven initialization with salvage; deterministic container/position selection. [major] Container Placement: new PlacementInitialized event; refined ContainerChanged/PositionChanged gating. [major] Container Placement: accurate payloads (previous/current container & position); swap-aware add/move. [major] Linked Container: primary and linked mirroring (equipment single-slot semantics). [major] Linked Container: redirect when placed in linked first; move owner to primary, then mirror. [major] Nested Container: auto-create on activation; lifecycle tied to owner; auto-remove on owner removal. [added] Allowed build platforms: Linux and Mac. [added] Spatial layout: PerCell and BitSetRows fit algorithms; custom hook via TestWithCustomAlgorithm (C++). [added] Occupancy Masks with rotation support and in-editor mask UI (paint/mirror/rotate/validate). [added] Drag & Drop: UNinjaInventoryDropZoneWidget + UNinjaInventoryDragDropOperation integration for world/container drops. [added] Automated test suite covering placement, events, swaps, nested/linked, eviction, container removal. [improvement] Container Placement: single graceful retry path (TryPlaceWithRetry) for transient failures. [improvement] Container Placement: ResolveById for authoritative container instance resolution. [improvement] Linked Container: listens to item + container events; clears mirror on container removal/unequip. [improvement] Consume ability: expanded logs/comments to clarify cancellation causes. [improvement] Attribute Set: replaced ensure with check/warning for Equipment Managers. [improvement] Test utilities consolidated into shared event listeners and helpers. [fix] Crash when removing items without stacks fragments. [fix] Consume from gameplay events condition corrected. [fix] Equipment State ability now ends correctly when no animation is found. [fix] Linked Container: prevented duplicate subscriptions and stale mirror memory on deactivate. [fix] Nested Container: prevented duplicate creation on re-activation or load. [fix] Crash when loading inventory with certain stack values.

[added] Completed "Load" functionality. [added] New Scene Selector (`EquipmentSceneComponentProvider`) based on an interface, for advanced logic. [improvement] Added the source to pickup actors. [improvement] Exposed consumable objects in the Consumable Ability. [fix] Fixed `IsSuccessful` in the `FInventoryItemContext`.

[added] Support for Unreal Engine 5.5. [improvement] Added the appropriate Editor Category for all Inventory Assets in the Content Browser. [improvement] Improved the logic for the Inventory Animation Ability activation check. [fix] Fixed the Equipment State Changed broadcast not being called.

[improvement] Added a default implementation to the Equipment Actor Interface so it can use the Equipment Receiver Component.

[improvement] Organizing the code to eventually auto-generate Mesh Components for slots. [improvement] Added a component that enables direct integration with Ninja Combat. [improvement] Added a function that can assume the container from an item in safe scenarios. [fix] Fixed initial memories for Level and Quality fragments. [fix] Fixed filters for Data Tables. [fix] Fixed a crash while checking for empty Inventory Avatars. [fix] Fixed a corner-case of adding items to the first position in a container, without a pre-set container and multiple stacks. [fix] Fixed the helper function that checks the result of an item context and provides a path.
