unity-singleton-pattern

To create a global Unity manager that persists across scene loads, you use the PersistentSingleton implementation. This pattern maintains your manager's state and data throughout scene transitions without being destroyed or duplicated.

The best way to handle duplicate global managers in Unity is through strict lifecycle control. The Singleton implementation automatically destroys duplicate instances to keep the original, while RegulatorSingleton destroys older instances to support hot-swapping with the newest manager.

Yes, you can use a lightweight global reference in Unity without strict duplication enforcement by implementing StaticInstance. It provides accessible global references for your GameObjects without the overhead of destroying duplicate instances.

Your Unity singleton has inconsistent states during scene transitions because it lacks a controlled lifecycle. Without deterministic startup and correct destruction rules, duplicates arise, leading to hard-to-trace bugs in your core systems.

You need a RegulatorSingleton for Unity game development when you want to hot-swap managers. It keeps the newest instance by destroying older ones, ensuring your global manager updates dynamically without retaining outdated references.
