Generic Singleton

Generic version of singleton for both MonoBehaviour and Standard classes.

Singleton is a development pattern that prevents having multiple instances of the same component in a scene. It allows also any script to access this one wihout requiring a manual link between the two.

This one is a generic Singleton that allows you to inherit from it from your class to access its instance with the static Instance property. There are two singleton:

  • Singleton that inherits from MonoBehaviour
  • SimpleSingleton that does not

Usage

Extends the Singleton<T> (for MonoBehaviour singletons) or SimpleSingleton<T> (for standard classes singletons) class from your own classes like this:

public class MyBrandNewClass : Singleton<MyBrandNewClass> {
// ... fields, methods, etc.
}

You can call it from other scripts like this :

MyBrandNewClass.Instance.PublicMethod()

See Transition class for a demo.
