CastInputForwardSystem manages the communication between a Spatial SDK app and the MQDH Cast window. Per execute() tick it retrieves the updated mouse/keyboard state info from MQDH Cast and processes the info to manipulate the camera/send input down into the Spatial SDK application.

Signature

class CastInputForwardSystem(val vrActivity: VrActivity, val initialPose: Pose? = null) : SystemBase

Constructors

CastInputForwardSystem ( 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

CastInputForwardSystem

Properties

executeCount : Long [Get]	The number of times this system's SystemBase.execute method has been called by the system manager. Incremented automatically before each execution cycle. Useful for performance monitoring. Signature var executeCount: Long
initialPose : Pose? [Get]	Optional pose to initialize the virtual camera with. If null, uses Scene.getViewOrigin(). Signature val initialPose: Pose? = null
maxPointerDistance : Float [Get]	Signature val maxPointerDistance: Float = 5.0f
movementSpeed : Float [Get][Set]	Signature var movementSpeed: Float
pitchSensitivity : Float [Get]	Signature val pitchSensitivity: Float = 100.0f
shiftMultiplier : Float [Get][Set]	Signature var shiftMultiplier: Float
systemManager : SystemManager [Get][Set]	The SystemManager that this system is registered with. Provides access to other systems and the scene. Initialized during system registration. Signature lateinit var systemManager: SystemManager
vrActivity : VrActivity [Get]	The VrActivity of the Spatial SDK application. Signature val vrActivity: VrActivity
yawSensitivity : Float [Get]	Signature val yawSensitivity: Float = 100.0f

Methods

associateSystemManager ( systemManager )	Associates this system with a SystemManager. Called during registration. Throws RuntimeException if the system is already associated — each system instance can only belong to one manager. Signature fun associateSystemManager(systemManager: SystemManager) Parameters `systemManager: SystemManager` The system manager that will own and execute this system.
calculateDirectionVector ( normalizedX , normalizedY , fovLeft , fovRight , fovUp , fovDown )	Signature fun calculateDirectionVector(normalizedX: Double, normalizedY: Double, fovLeft: Double, fovRight: Double, fovUp: Double, fovDown: Double): Vector3 Parameters `normalizedX: Double` `normalizedY: Double` `fovLeft: Double` `fovRight: Double` `fovUp: Double` `fovDown: Double` Returns `Vector3`
delete ( entity )	Called when an SystemBase.delete is removed from the scene. Override to clean up any per-entity state this system maintains, such as cached components, tracking maps, or native resource handles. Signature open fun delete(entity: Entity) Parameters `entity: Entity`
destroy ()	Called during system shutdown to release all resources held by this system. Override to dispose of native handles, close streams, and clear any global state accumulated during the session. Signature open override fun destroy()
destroyPanelAppStreamer ()	Signature fun destroyPanelAppStreamer()
equals ( other )	Checks if this system is equal to another object. Two systems are considered equal if they are the same instance or share the same Kotlin class, regardless of configuration state. Signature open operator override fun equals(other: Any?): Boolean Parameters `other: Any?` The object to compare with. Returns `Boolean` True if the other object is the same system instance or the same system class.
execute ()	Called each frame by the SystemManager to perform this system's per-tick logic. Override to query entities with relevant components and apply updates. Signature open override fun execute()
getDependencies ()	Returns the execution ordering dependencies for this system. Override to declare which other systems must run before or after this one using SystemDependencies. Signature open fun getDependencies(): SystemDependencies? Returns `SystemDependencies?` The dependency configuration, or null if this system has no ordering constraints.
getScene ()	Returns the Scene that this system operates within. Delegates to the associated SystemManager to retrieve the active scene instance. Signature fun getScene(): Scene Returns `Scene` The scene containing the entities and rendering state for this system.
hashCode ()	Returns the hash code of this system, based on its Kotlin class identity. Consistent with the SystemBase.equals implementation — systems of the same class produce the same hash code. Signature open override fun hashCode(): Int Returns `Int` The hash code derived from this system's Kotlin class.
onPause ()	Signature fun onPause()
onResume ()	Signature fun onResume()
setEnabled ( enabled )	Signature fun setEnabled(enabled: Boolean) Parameters `enabled: Boolean`
