NEXUS Inventory is a professional game development framework: modular item infrastructure with a deterministic core, visual tooling, and a server-authoritative transaction layer — production-ready game systems a team can extend, diff, and ship.
◆ Affix Forge — seeded, budget-governed generation.
Tiered affixes roll under designer-set budgets per level and rarity. Same seed ⇒ identical item, forever — proven by shipped tests and demoable in one click. Rare stays rare because you control the valve.
◆ Transaction Ledger — anti-duplication by construction.
Every add, move, split, socket, enchant, craft and trade is a validated, idempotent, quantity-conserving transaction in an append-only journal. A conservation audit proves integrity on load and in the runtime overlay. Watch a dupe exploit die in the demo.
◆ Item Lineage.
Every item remembers its full history — forged, socketed, enchanted, traded — persisted with your saves, readable in tooltips, the editor viewer, and the F9 Inventory Lens overlay.
◆ Versioned saves from day one.
Schema v1 with an automatic migration chain, a documented reference migration, and corruption recovery that quarantines and guides instead of losing data. Upgrade the asset mid-project without touching your players' saves.
Full catalog-card systems: item database · instances & stacks · durability · weight · rarity · affixes with random stats · sockets & gems · enchantments · equipment with stat aggregation · containers with limits & filters · loot tables (seeded) · trading (atomic) · crafting (stations, professions, crit/failure) · valuation · item XP & levels · serialization.
Server-ready: authority modes (Server / Client-Predictive with PendingAck), serializable compact transactions, deterministic seeded rolls, and a pure-C# domain that runs on dedicated servers without Unity. Works with your transport — FishNet, Mirror, NGO, or custom (integration pattern in the manual).
Tooling that pays for itself in minutes: Item Database window (search, create, validate), Affix Forge window, Diagnostics window (broken refs, duplicate ids, budget outliers, code↔asset parity), Lineage Viewer, guided inspectors with live valuation preview, one-command showcase demo scene.
Documentation a team can stand on: quick start (first success in ten minutes), 20-section manual, full API reference, samples guide, 20-question FAQ, migration guide, changelog, and three ready-to-record tutorial scripts.
Requirements & compatibility: Unity 2021.3 LTS / 2022.3 LTS / Unity 6. Built-in, URP and HDRP (pipeline-agnostic overlay UI). Zero third-party dependencies. Full C# source with XML documentation; the domain core is engine-agnostic pure C#. Runtime UI uses Unity's built-in uGUI module.
Support promise: every review answered; response within 48h on business days; documented updates with a public roadmap (vendor & wallet windows, TMP theming, transport samples next).
Roadmap: 1.1 vendor & wallet windows + theming layer · 1.2 degradation hooks, salvage rules, bulk CSV import · 1.3 second transport sample, save-slot UI, localization hooks.
