Info

• The Singleton pattern is a bit rigid. hence the service locator pattern.
• It is still meant for global access and should not be overused.
• Similar to a singleton, only one instance at a time, and usually represents some kind of Manager

<aside> 💡

Consider using Dependency Injection instead!

Services

• An object accessible from the static context of the app, there is always only one available instance for a given type.
• Any class inheriting from IService can be registered as a service within AppCore.Services
• Use class AppCore.Services

Registering

• You can use AppCore.Services.Register and AppCore.Services.Unregister to handle your own custom services
• If your MonoBehaviour is supposed to be a service during its whole lifetime use AServiceBehaviour
  • It registers itself in Awake and unregisters in OnDestroy

Obtaining

• GetReturns registered instance or null
• TryGet - Returns true and outs instance if its registered, return false otherwise
• WhenRegistered - Registers callback to get when service is registered, if service is already registered method is invoked directly
• AwaitRegistered - UniTask variant to WhenRegistered, is awaitable in async call
