unity-architecture

Runtime architecture for Unity C# projects - composition over inheritance, thin MonoBehaviours with logic in plain C# classes, dependency injection options, ScriptableObject event channels vs C# events vs message buses, singletons and bootstrapping, update loop ownership, initialisation order, data-driven design, model-view separation, state machines, assembly boundaries enforcing dependency direction, testing with the Unity Test Framework, and when to adopt ECS/DOTS. Load when designing systems, splitting code into assemblies, choosing communication patterns, structuring for testability, or reviewing coupling.
