Understanding the Service Locator pattern
The Service Locator pattern is a creational design pattern, similar to the Singleton pattern. It provides a centralized point of access where user classes can obtain services without being tightly coupled to the specific classes that implement those services. This allows for more flexibility and decoupling in the system’s architecture.
For instance, instead of instancing AudioStreamPlayer2D nodes to play sound effects, a node could rely on a SoundEffectService class that would instantiate, play, and handle the life cycle of the AudioStreamPlayer2D node that would play the requested sound effect. This adds a layer of indirection between the user class and the concrete service class, effectively decoupling them.
By providing a centralized registry where any class can retrieve a given service, the Service Locator pattern allows for loose coupling between different components in the system. It’s especially useful if you think...
