LiteNinja Camera Services is a collection of Camera-related services for Unity projects.

A service that allows registering and retrieving cameras.

ICameraRegistry is an interface that defines the contract for a camera registry service. It provides methods for registering, retrieving, and unregistering cameras.

Here are the key methods of the ICameraRegistry:

• RegisterCamera(string id, Camera camera): This method allows you to register a camera with a unique string identifier. If a camera with the same identifier is already registered, it will be replaced.

• GetCamera(string id): This method allows you to retrieve a camera using its unique string identifier. If no camera is registered with the given identifier, it returns null.

• UnregisterCamera(string id): This method allows you to unregister a camera using its unique string identifier. If no camera is registered with the given identifier, the method does nothing.

• CameraIds: This property returns an array of all registered camera identifiers.

• OnCameraChanged: This event is invoked when a camera is registered or unregistered. The event handler receives the identifier of the changed camera.

CameraRegistry is a class that implements the ICameraRegistry interface. It uses a dictionary to store cameras, identified by a unique string ID.

Here's a basic usage example:

// Create a new CameraRegistry instance
ICameraRegistry cameraRegistry = new CameraRegistry();

// Register a camera
Camera mainCamera = Camera.main;
cameraRegistry.RegisterCamera("Main", mainCamera);

// Retrieve a camera
Camera retrievedCamera = cameraRegistry.GetCamera("Main");

// Unregister a camera
cameraRegistry.UnregisterCamera("Main");

Remember to add a listener to the OnCameraChanged event if you want to be notified when a camera is registered or unregistered:

cameraRegistry.OnCameraChanged.AddListener((string id) => {
    Debug.Log($"Camera changed: {id}");
});
