• Works in both Development and Production
• Instantiates Singleton objects if they aren't available by Lazy Load
• You can configure fields in the inspector for singleton objects in the preload scene

This package can be added to your project via Git UPM. To add this package, copy:

https://github.com/UnityCommunity/UnitySingleton.git

and add it as a git package in the Unity Package Manager by clicking on the "+" icon on the top left of the Package Manager Window, and selecting "Install package from git URL".

• Create your own Singleton classes by extending the Generic ✨ Singleton ✨ class. (🚀 Check out the example GameManager in the example _Preload scene.)
• Attach your singleton classes to a GameManager game object in a _Preload scene of your own.
• Edit the variables inside the inspector
• Run the game and enjoy!

Add using UnityCommunity.UnitySingleton; for using the classes.

• Use Singleton<T> for plain C# classes.
• Use MonoSingleton<T> if you want a Scene-based singleton which is not persistent across scenes.
• Use PersistentMonoSingleton<T> if you want a Global and persistent singleton across scenes.
