Unity Architect

Replace singletons with ScriptableObject event channels and variable containers like FloatVariable for cross-system communication, eliminating tight scene coupling and global state while maintaining modular, data-first architecture.

A RuntimeSet in Unity is a ScriptableObject-based pattern used to track active entities without relying on global state or singletons. Use RuntimeSet tracking to manage active entities modularly when you need to decouple systems from scene hierarchy dependencies.

To refactor God MonoBehaviours, decompose them into single-responsibility components wired through the Inspector using ScriptableObject-driven design, replacing GameObject.Find calls and God classes with self-contained prefabs and event-channel messaging for clean modular architecture.

This ScriptableObject-first architecture approach works for both refactoring existing Unity projects and creating new systems, applying modular SOP-driven components, reusable runtime sets, and event-channel messaging to eliminate spaghetti architecture regardless of project age.

Serialization hygiene rules for Unity ScriptableObjects include avoiding scene-instance references inside SOs and using correct EditorUtility.SetDirty usage, preventing Unity serialization surprises and ensuring reliable data persistence across editor and runtime environments.

Avoid GameObject.Find in Unity architecture because it creates tight scene coupling and performance bottlenecks. Replace it with ScriptableObject event channels and RuntimeSet patterns to achieve decoupled, singleton-free systems that scale without hard scene dependencies.
