RPG Stat & Attribute System — Data-Driven Modifiers

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.
