SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Implements a complete Unity 6+ save and persistence system that ensures reliable state capture, atomic writes, versioned data, multi-slot support, auto-save, and optional cloud storage integration for Unity projects.

Core Features & Use Cases

Atomic and crash-safe saves using .tmp and .bak in a persistent data path.
Versioned SaveData with migration pipelines to evolve schemas without data loss.
Multi-slot saves, cloud or platform-backed storage, and ISaveable-based state capture/restoration for flexible game persistence.

Quick Start

Install the SaveManager into your Unity project and begin saving and loading game state with a few simple calls.

FAQPage Schema

How do I implement atomic writes in a Unity save system?▼

Migrate Unity save data by using versioned SaveData and migration pipelines. This approach evolves schemas without data loss, allowing you to update your game's data structure while preserving existing player progress across different game versions.

What is the best way to handle multi-slot saves in Unity?▼

Multi-slot saves in Unity are handled by a SaveManager that supports capturing and restoring state via the ISaveable interface. This allows flexible game persistence across distinct save slots, giving players multiple independent playthroughs.

Can I integrate cloud storage with Unity game persistence?▼

Yes, Unity game persistence supports optional cloud or platform-backed storage integration. This extends local saving capabilities to remote servers, enabling cross-platform save synchronization for your Unity 6+ projects.

Does this Unity save system support automatic autosave workflows?▼

Yes, this Unity save system supports an auto-save workflow. It automatically captures game state at intervals or events using the ISaveable interface, ensuring continuous persistence without requiring manual save calls from the player.

Why do I need migration patterns for Unity save data?▼

Migration patterns are needed for Unity save data to handle schema evolution across game updates. By implementing versioned SaveData, you ensure that older save files remain compatible with newer game versions, preventing data loss.
