Save&&Load System

Overview

The Generic Inventory System (GIS) provides full serialization support through its inventory subsystem and allows complete customization of its underlying logic via the inventory factory.

Inventory Subsystem

GIS offers a comprehensive API through GIS_InventorySubsystem for creating/duplicating item instances, collections, and saving/loading inventories, item collections, and item instances.

Save/Load Example

GIS provides a robust serialization API to easily integrate with any dedicated save system.

You only need to focus on saving the InventoryRecord (the inventory’s save data) to disk or a database and retrieving it to initialize the inventory system.

In the demo included with the GIS's paired project, I’ve implemented a simple component and guid based save manager to demonstrate how to use the serialization API.

Inventory Factory

The API provided by GIS_InventorySubsystem is essentially a wrapper around GIS_InventoryFactory.

You can inherit from GIS_InventoryFactory in Blueprint or C++ to fully customize GIS’s underlying operations.

Additionally, you need to specify your custom inventory factory class in Project Settings -> GIS Inventory System Settings.
