RPG Stat & Attribute System — Data-Driven Modifiers
Data-driven RPG stat & attribute system. Author stats in the Inspector (no code), generate a type-safe enum, then drive them with modifiers, events, a live HUD and collection stats. Zero dependencies.

Stop hard-coding stats. StatSystem is a data-driven stat & attribute framework: you
define your stats as data in a ScriptableObject catalog — id, type, default,
min/max/clamp, category — and one click generates a type-safe StatId enum. No more
editing the package to add a stat, and no stringly-typed access.
Each entity gets its own live stat set from a drop-in component, so 100 NPCs share one
catalog but keep independent values. Works for any genre — RPG, sim, survival, tower
defense, crafting — and any render pipeline, with zero dependencies and full C# source.
Everything is push-based: subscribe to a stat, bind a field with [SubscribeToStat], or
read a live StatRef<T>. Modifiers are additive + multiplicative and source-tagged, so a
buff or a piece of equipment removes cleanly. Collection stats hold inventories. A
generic OnGUI HUD renders any catalog with no hard-coded names.
Seven playable demos (each with an in-scene usage guide that shows the exact API call),
six ready catalogs, an offline RTF manual with a step-by-step guide, and 157 EditMode
tests are included.
