FoxEasySave — Slot-based key-value saving for Blueprints, no USaveGame subclass required

Save and load named values to disk without ever creating a USaveGame subclass. FoxEasySave treats every save as a slot full of typed key-value pairs, with built-in versioning, automatic schema migration, sync and async disk I/O, and a player-profile pattern. Beginner-friendly by design, with a full concept guide included.

KEY FEATURES

1. No USaveGame subclass — A slot is just a name. Skip the boilerplate of defining a save class, casting, and wiring properties; just save and load named values directly.

2. Typed setters and getters — One clear node per type for String, Int, Float, Bool, Vector, Transform, Soft Object Reference, and GameplayTag, so your graphs stay readable.

3. Defaults on load — Every Load node takes a default value. Missing keys never crash and never return nil; you simply get your default back.

4. Auto-versioning with migration — Each slot tracks its own version. Register a migration delegate and old saves are transformed to the new schema automatically on load, without breaking existing player saves.

5. Sync and async disk I/O — Use synchronous SaveSlot and LoadSlot at startup or level transitions, and latent SaveSlotAsync and LoadSlotAsync to save mid-game without frame hitches.

6. Player Profile pattern — Set an active profile slot once, then save and load against it through dedicated profile nodes, including a one-call SwitchActiveProfile that saves the current profile and switches in one step.

7. GameInstance subsystem — Built on UFoxSaveSubsystem, the slot cache persists across level transitions, and BlueprintAssignable events OnSlotSaved, OnSlotLoaded, and OnSlotMigrated let your UI react to save activity.

8. Slot management and metadata — Create, delete, duplicate, and query slots, and read each slot's last-saved time, version, value count, and estimated size for your load menu.
