UE Serialization & Save Games

Target engine: UE 5.8. APIs below are verified against the 5.8 headers; older forms are listed under "Deprecated — do not use".

This skill covers persisting game state: USaveGame objects through UGameplayStatics, the platform ISaveGameSystem, FArchive binary serialization, UPROPERTY(SaveGame) actor snapshots, save versioning, and config/settings storage. Build.cs modules: Core, CoreUObject, Engine; add DeveloperSettings to PublicDependencyModuleNames for UDeveloperSettings, and Json + JsonUtilities to PrivateDependencyModuleNames for FJsonObjectConverter.

Context

Read .agents/ue-project-context.md if it exists (module names, conventions, enabled plugins, GAS/networking setup). Do not stop if it is missing.

Identify the area from the request and the codebase. Ask only when two plausible readings would produce different code.
