CupkekGames Packages

Luna ships on top of a wider ecosystem of 49 CupkekGames UPM packages — small, single-concern libraries (object pooling, service location, data catalogs, save/load, RPG stats, inventory, …) that Luna and the GameFull sample are built from. This section documents each one. This page is the map; the Architecture & Distribution page is the full deep-dive.

💡 Most users never touch this section. If you just want the UI Toolkit component library, install com.cupkekgames.luna from the Asset Store — its dependencies are bundled as transitives. The packages below matter only if you're running the GameFull sample or building a full game on the CupkekGames systems.

ℹ️ Used in a real game. This full package architecture — every tier below, foundation through domain — is the stack that powers Hero Manager, the RPG built by CupkekGames. The GameFull sample is the same architecture, trimmed down to a runnable scaffold you can start from.

How the packages are organized

Three tiers, lowest-level first:

Tier	What's in it
Foundation primitives	Single-concern, (near-)leaf packages extracted from the former `core` package — `singletons`, `pool`, `fadeables`, `keyvaluedatabases`, `editorui`, `editorinspector`, `packagemanager`, `input`.
Foundation dependents	Build on one or more primitives — `prefabloaders`, `assetfinder`, `services` (the ServiceLocator DI layer).
Domain layer	Game systems on top of the foundation + data layer — `luna`, `data`, `graphs`, `gamesave`, `rpgstats`, `inventory`, `settings`, `combat`, and more.

The full per-package dependency graph lives in Architecture & Distribution.

Custom Package Manager

The sibling packages are served from the CupkekGames UPM scoped registry at https://www.docs.cupkek.games/upm, not the Asset Store. You don't edit Packages/manifest.json by hand — a dedicated editor window does it for you:

com.cupkekgames.packagemanager is the bootstrap package. Install it first (git URL or local file: path); it self-registers the scoped registry into your manifest so everything else resolves natively in Unity's Package Manager UI.
Tools > CupkekGames > Package Manager lists every com.cupkekgames.* package with status, version, and one-click install. Install GameFull Packages writes the registry block and installs the whole domain graph atomically — one manifest write, one domain reload.

See the Package Manager package for the API, and the registry/distribution details on the architecture page.
