Class Singleton<T>

Namespace

Gamelogic.Extensions

Assembly

Assembly-CSharp.dll

Provides a generic implementation of a singleton-like pattern for MonoBehaviour classes. This class automatically searches for an existing instance in the scene or logs an error if none or more than one are found.

Remarks

Singletons usually manage their own creation, but it is common in Unity projects to have a singleton already placed in the scene. In this sense, this class really checks whether an instance can be used as a singleton, and then provides access to the instance.

If you want to create a singleton that is not already placed in the scene, you can use put
<xref href="Gamelogic.Extensions.SingletonPrefabSpawner%601" data-throw-if-not-resolved="false"></xref> in the scene instead.
