Class DontCreateNewSingleton<T>

Utility class to make inheriting types singletons.

public abstract class DontCreateNewSingleton<T> : MonoBehaviour where T : DontCreateNewSingleton<T>

Remarks

Assumes complete ownership of the parent GameObject.

Unlike Singleton<T>, this does not create a new instance of T if there are no existing ones.

Is there an existing instance of type T?

public static bool HasInstance { get; }

The singleton instance of type T.

public static T? Instance { get; }

Check HasInstance to check if an instance actually exists.

protected virtual void Awake()

If Instance is null, sets it to this, otherwise, destroys the current GameObject. All inheriting classes must invoke this method if overriding it.

Tries to get the singleton T instance.

public static bool TryGetInstance(out T? instance)
