This makes it possible to iterate on a Spatial SDK app without needing to don/doff the headset. This requires usage of the MQDH Cast feature, which mirrors your headset to your computer.

This should not be enabled in the release version of an app.

override fun registerFeatures(): List<SpatialFeature> {
  val features = mutableListOf<SpatialFeature>()
  if (BuildConfig.DEBUG) {
    ...
    features.add(CastInputForwardFeature(this))
  }
}

Signature

class CastInputForwardFeature(val vrActivity: VrActivity, val initialPose: Pose? = null) : SpatialFeature

Constructors

CastInputForwardFeature ( vrActivity , initialPose )

Signature

constructor(vrActivity: VrActivity, initialPose: Pose? = null)

Parameters

                                                    vrActivity:
VrActivity

The VrActivity of the Spatial SDK application.

                                                    initialPose:
Pose?

Optional pose to initialize the virtual camera with. If null, uses Scene.getViewOrigin().

Returns

CastInputForwardFeature

Properties

initialPose : Pose? [Get]	Optional pose to initialize the virtual camera with. If null, uses Scene.getViewOrigin(). Signature val initialPose: Pose? = null
vrActivity : VrActivity [Get]	The VrActivity of the Spatial SDK application. Signature val vrActivity: VrActivity

Functions

earlySystemsToRegister ()	Override this method to register your systems that should be executed with PriorityGroup EARLY. Signature open fun earlySystemsToRegister(): List<SystemBase> Returns List A list of SystemBase objects
getDependencies ()	Override this method to define a list of dependencies required by this feature. This will be verified at runtime. Example: // MyCustomFeature.kt override fun getDependencies(): List<KClass<out SpatialFeature>> { return listOf(ToolkitFeature::class) } @return A list of SpatialFeature classes representing the dependencies. Signature open fun getDependencies(): List<KClass<out SpatialFeature>> Returns List
lateSystemsToRegister ()	Override this method to register your systems that should be executed with PriorityGroup LATE. Signature open override fun lateSystemsToRegister(): List<SystemBase> Returns List A list of SystemBase objects
loadLibrary ( libName )	Loads a native library into the application. Signature open fun loadLibrary(libName: String) Parameters libName: String The name of the library to load.
onCreate ( savedInstanceState )	Called when the application is created. Override this method to perform actions during the OnCreate() lifecycle of the application. Signature open fun onCreate(savedInstanceState: Bundle?) Parameters savedInstanceState: Bundle? The saved instance state of the application.
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. Signature open fun onDestroy()
