Metroidvania Tutorial Series - Better Architecture: Service Locator Pattern | Data Persistence in Unity | Ep. 04

In this episode of the Unity Scene Persistence series, we introduce the Service Locator pattern as a cleaner, more scalable way to manage persistent systems across scenes. Instead of relying on singletons or fragile references, we centralize access to core systems like parallax, spawning, and camera control—making our architecture more flexible and easier to maintain as the project grows. By the end of this video, you’ll understand how to use a Service Locator to simplify your scene management and build systems that actually scale. In this episode you’ll learn how to: • Replace expensive "Find" searches with a Service Locator • Access persistent systems cleanly across scenes • Improve the structure of your Bootstrap architecture This episode is part of a larger series where we build a complete Unity scene persistence system—from Bootstrap scenes to scalable game architecture. If you're ready to move beyond prototypes and build systems that hold up in real projects, this series is for you.
