Build every gameplay system as a self-contained UPM package. Data lives in ScriptableObjects, behavior lives in small single-responsibility MonoBehaviours, and systems talk through SO Event Channels — never direct references.

| One system = one UPM package | Create a "shared contracts" package with interfaces | | Data in ScriptableObjects, behavior in MonoBehaviours | Put data and behavior in the same class |

| MonoBehaviour [SerializeField] only for SO refs, component refs, scene refs, UnityEvents | [SerializeField] primitives (float, int, bool, string, LayerMask, enum, AnimationCurve) directly on MonoBehaviours — these belong in an SO Config asset | | SO Event Channels for cross-system communication | Use singletons, service locators, or static managers |

在构建可重用的 Unity 游戏系统、创建 UPM 包或为库存、战斗、对话、任务或保存/加载等游戏系统设计基于 ScriptableObject 的模块化架构时使用。当连接多个需要在没有直接依赖关系的情况下进行通信的独立 Unity 包时也可使用。 来源：eyenpi/unity-systems-skills。
