# 2.8.1 Engine support: 5.4 The "Need for Speed" edition This is one of the biggest updates since 2.0 and was on the border of becoming version 3.0. This update changes a good chunk of behaviour under the hood and brings lots of optimizations. `IFP` is already extremely fast and is probably the fastest and most feature-rich inventory system on the marketplace, but that doesn't mean there isn't room for improvements. Highlights: * Added **ItemStructObject**'s, which are a brand new way of handling gameplay logic for items. This is one of the biggest and most exciting features added to `IFP` since release. * Improved editor workflow. * Several performance improvements. * Updated documentation. *** ## Items * Added **ItemStructObject**'s, which are a brand new way of handling gameplay logic for items. [Documentation](https://inventoryframework.github.io/classes-and-settings/da_coreitem/) has been added * You can now drag the item data asset into the viewport to place the item actor. This is also possible by clicking and dragging the asset icon in the `ItemEditor` tool. * The `VerifyData` button has been removed. The logic has been moved into the `IsDataValid` function, which is ran whenever an asset is saved. * Added buttons for opening the item actor and item struct object. * Item assets thumbnails in the content browser and drop down windows now use their inventory image or the developer image as the thumbnail image. * Added **ItemType** tag to items to simplify the item type logic for items. * Shape is now baked into the data asset, greatly improving the performance of several functions that relied on the items shape. * **GetItemDescription** will now replace any text that includes "< Tag value name >" with the value of that tag value. For example; "Current Durability: \" will be changed to Current Durability: 20" if the tag value was 20. The apple, helmet and gun items uses this for an example. You can also style your floats with the new `Rich Text Wrapper` parameter. (Read code comment for more info) * Items can now have sockets, just like a static mesh or a skeletal mesh. This is achieved through the socket manager object on the item asset and can be edited through the `ItemEditor` toolbox. ## Inventory * When replicating containers to clients, server now clears the tile map when sending the RPC and has clients regenerate it when it reaches them, resulting in an average 20% smaller RPC sizes. * A new **ID\_Map** system has been added. This allows the system to find ANY container or item in constant time, meaning it takes the same amount of time to find a container or item in index 0 as it takes to find a container or item at index 1000. This also means that **GetItemByUniqueID** has been reworked and is virtually free and this has had a tremendous performance improvement for projects with hundreds of containers or items in one inventory component. * A new **IndexCoordinates** system has been added, allowing the system to instantly convert a tile into an index. This wasn't expensive, but the system used this convertion so much, the small cost started to pile up. * **GetFirstAvailableTile** is no longer blueprint overridable. * The inventory component now has a custom icon. * Added **GetItemCount** function. * Added **GetItemsByType** function. * Added **GetItemsParentContainer** function. * Added a **DoNotBind** parameter to **CreateAttachmentWidgetForItem** so it's easier for people to do custom bindings. ## Interfaces * The **I\_WidgetUpdates** interface has been renamed to **I\_ExternalObjects**. The \`ExternalWidgets system has also been reworked to not be limited to just widgets. * Many of the functions inside of **I\_WidgetUpdates** have been reworked to expose more parameters and have better categories. ## Tools * The `ItemEditor` tool has had a layout make-over. * The `ItemInspector` tool has been disabled for runtime. Should only be used in the `ItemEditor` from now on. ## Preview Actor * The collider actor has been removed. This actor was a overkill solution to a rare bug. This has also improved the garbage collector performance. * Added a new option to skip the cloning process. If enabled, it'll just attach itself to the owner. This has almost doubled its performance. * All actors spawned by the preview actor now get labeled as one with the new **I\_Inventory** -> **SetIsPreviewActor** function. You can then use the **I\_Inventory** -> **IsPreviewActor** to find out if that actor instance is a part of the preview actor system or not. * Preview actor now supports leader poses. Documentation has been updated. ## Documentation * `DA_CoreItem` has been updated. * A new `Optimizations` page has been added. ## Bugs * Default items declared in the item data asset containers would fail to spawn. * Item struct in item data asset containers would say "No Item Available" * Widget factories were using the wrong blueprint type. * Crash if invalid data was passed into **GetItemsTagValues** * Generated item icons would go into the wrong folder. * Clicking on a specific spot on non-custom shaped items did not treat that spot as the anchor point. ### 2.8.1 * Disabled struct object creation on preview actor instances. Bug fixes: * Clients item data would not include the item struct object in some scenarios. * Moving an item via double click could cause item duplication. * Dropped items would not have their containers setup correctly, which would also cause those containers to get lost when picking up a dropped item. * The stack variables inside the data asset would get hidden if max stack was set to 1. *** ## Color Sheet: **functions** - **variable** - **category** - **class**
