Namespace UnityEngine.XR.Management

Classes

XRConfigurationDataAttribute

This attribute is used to tag classes as providing build settings support for an XR SDK provider. The unified setting system will present the settings as an inspectable object in the Unified Settings window using the built-in inspector UI.

The implementor of the settings is able to create their own custom UI and the Unified Settings system will use that UI in place of the build in inspector. See the Extending the Editor portion of the Unity documentation for information and instructions on doing this.

XRLoader

XR Loader abstract class used as a base class for specific provider implementations. Providers should implement subclasses of this to provide specific initialization and management implementations that make sense for their supported scenarios and needs.

XRLoaderHelper

XR Loader abstract subclass used as a base class for specific provider implementations. Class provides some helper logic that can be used to handle subsystem handling in a typesafe manner, reducing potential boilerplate code.

XRManager

Class to handle active loader and subsystem management for XR SDK. This class is to be added as a component on a GameObject in your scene. Given a list of loaders, it will attempt to load each loader in the given order. The first loader that is successful wins and all remaining loaders are ignored. The loader that succeeds is accessible through the activeLoader property on the manager.

Depending on configuration the XRManager component will automatically manage the active loader at correct points in the scene lifecycle. The user can override certain points in the active loader lifecycle and manually manage them by toggling the Automatic Loading and Automatic Running properties through the inspector UI. Disabling Automatic Loading implies the the user is responsibile for the full lifecycle of the manager. Toggling this to false also toggles automatic running to false.

Disabling Automatic Running implies that the user is responsible for starting and stopping the activeLoader through the StartSubsystems() and StopSubsystems() APIs.

Automatic lifecycle management is executed as follows

• OnEnable -> InitializeLoader(). The loader list will be iterated over and the first successful loader will be set as the active loader.
• Start -> StartSubsystems(). Ask the active loader to start all subsystems.
• OnDisable -> StopSubsystems(). Ask the active loader to stop all subsystems.
• OnDestroy -> DeinitializeLoader(). Deinitialize and remove the active loader.
