Item Management
Create items, categories, currencies, and crafting recipes in an intuitive editor. Every aspect of the inventory flow is customizable, from the underlying data to the visuals.
Item Attribute System
Attributes drive item variants and can be bound directly to component properties, so a single item definition covers a whole family of in-game objects.
Predefined Schemas
Get started immediately with predefined schemas, or import and export your item data to move it between projects.
Item Restrictions
Apply restrictions to limit which items an inventory will accept.
Inventory Display
Use the built-in UI or customize it to match your game’s style and input method — mouse, controller, or touch. Items can be equipped in allocated slots, occupy multiple slots within a grid, and be dragged and dropped between them.
Item Actions
Assign item actions to perform operations directly from the inventory menu, including hotbar bindings.
Split Screen / Co-op
Supports split screen and co-op configurations, with full controller support.
Crafting
Craft new items from recipes you define in the editor.
Currencies
Create your own currencies and use them across shops and crafting.
Upgrades
Use item attribute values to build an upgrade system on top of your existing items.
Loot Items
Inventories can be configured for looting, so containers and defeated enemies use the same system as the player.
Save & Load
Supports saving and loading to disk, with full localization support for global releases.
