class DataModelInspectorFeature(val spatial: SpatialInterface, val componentManager: ComponentManager, val port: <Error class: unknown class>) : SpatialFeature

The Data Model Inspector (DMI) feature provides real-time debugging capabilities for the ECS in a Spatial SDK project.

More info: https://developers.meta.com/horizon/documentation/spatial-sdk/spatial-sdk-tooling-dmi/

DMI offers a live view of your scene’s data model directly in Android Studio, making debugging easier by allowing developers to:

Monitor entity attributes in real-time as they change during runtime

Temporarily modify entity attributes without rebuilding the application

Select entities either from the inspector panel or directly in the 3D scene

Search and filter entities and their attributes

This feature works in conjunction with the Meta Horizon Android Studio Plugin, which provides a dedicated panel for interacting with the data model. This should not be enabled in the release version of an app.

Functions

Name	Summary
componentsToRegister	open fun componentsToRegister(): List<ComponentRegistration> Override this function to define a list of components that should be used by the application.
earlySystemsToRegister	open fun earlySystemsToRegister(): List<SystemBase> Override this method to register your systems that should be executed with com.meta.spatial.core.PriorityGroup EARLY.
getDependencies	open fun getDependencies(): List<KClass<out SpatialFeature>> Override this method to define a list of dependencies required by this feature. This will be verified at runtime.
lateSystemsToRegister	open override fun lateSystemsToRegister(): List<SystemBase> Override this method to register your systems that should be executed with com.meta.spatial.core.PriorityGroup LATE.
loadLibrary	open fun loadLibrary(libName: String) Loads a native library into the application.
onCreate	open override fun onCreate(savedInstanceState: <Error class: unknown class>?) Called when the application is created. Override this method to perform actions during the OnCreate() lifecycle of the application.
onDestroy	open fun onDestroy() Called when the application is in onDestroy callback. Be aware that onDestroy() is not guaranteed to be called. Override this method to perform actions during the OnDestroy() lifecycle of the application.
onPauseActivity	open fun onPauseActivity() Called when the activity is in onPause callback. Override this method to perform actions during the OnPause() lifecycle of the application.
onResume	open fun onResume() Called when the application is resumed. Override this method to perform actions during the OnResume() lifecycle of the application.
onSceneReady	open fun onSceneReady() Called when the scene is ready. Override this method to perform actions during the OnSceneReady() lifecycle of the application.
onSpatialShutdown	open fun onSpatialShutdown() Called when the application is shutting down. Clean up all Spatial resources for your feature, e.g. entites.destroy(), in this callback.
onStart	open fun onStart() Called when the application is started. Override this method to perform actions during the OnStart() lifecycle of the application.
onStopActivity	open fun onStopActivity() Called when the activity is in onStop callback. Be aware that onStop() is not guaranteed to be called. Override this method to perform actions during the OnStop() lifecycle of the application.
onVRPause	open fun onVRPause() Called when the VR mode is paused. Override this method to perform actions during the OnVRPause() lifecycle of the application.
onVRReady	open fun onVRReady() Called when the VR mode is ready. Override this method to perform actions during the onVRReady() lifecycle of the application.
preRuntimeOnCreate	open fun preRuntimeOnCreate(savedInstanceState: <Error class: unknown class>?) Called before the application’s onCreate() method is called. Override this method to perform actions before the rest of the OnCreate() lifecycle of the application.
registerRequiredOpenXRExtensions	open fun registerRequiredOpenXRExtensions(): List<String> Override this function to define a list of required OpenXR extensions that should be enabled by your application.
systemsToRegister	open fun systemsToRegister(): List<SystemBase> Override this method to register your systems that should be executed com.meta.spatial.core.PriorityGroup NORMAL.
