Overview

The Advanced Save System plugin provides a comprehensive, production-ready solution for implementing save/load functionality in your Unreal Engine projects. It supports both Blueprint and C++ workflows with advanced features including async operations, auto-save, slot management, AES encryption, and cloud save integration (Steam Cloud & Epic Online Services).

Features

• Complete save/load system with Blueprint and C++ support for all common data types (int, float, bool, string, vector, rotator, transform)

• Multiple save slot management with metadata tracking (timestamp, play time, version, file size)

• Advanced slot operations: duplicate, rename, swap, and delete save slots

• AES encryption for secure save files with password-based key generation

• Cloud save integration supporting Steam Cloud and Epic Online Services with auto-detection (require platform configuration that needs to be done by you first.)

• Asynchronous save/load operations to prevent gameplay hitches

• Auto-save functionality with configurable intervals

• Quick save/load to default slot for one-button saving

• Save slot enumeration and detailed information retrieval

• Transaction-safe operations with comprehensive error handling and logging

• Extensible architecture allowing custom save game classes

• Game Instance Subsystem for persistent save management across levels

Platform-Specific Setup:

• Steam Cloud: Requires Steam SDK and configuration in DefaultEngine.ini

• Epic Online Services: Requires EOS configuration

• Cloud saves are optional - Core save system works without any platform setup

File Format:

• Standard Unreal Engine .sav format

• Optional AES encryption

• Cross-platform compatible

• Forward compatible with custom data structures

Extensibility:

• Inherit from UAdvancedSaveGame for custom save structures

• Override serialization for advanced use cases

• Add custom metadata fields

• You can also Implement custom encryption algorithms if needed

Best For:

• Single-player games

• Local multiplayer games

• Games requiring save file security

• Games with multiple save slots

• Games needing cloud save support

• Any game requiring robust save/load system

Not Suitable For:

• Pure multiplayer games with server-authoritative saves (use database instead)
