Syntax

public abstract class XREnvironmentProbeSubsystem : TrackingSubsystem<XREnvironmentProbe, XREnvironmentProbeSubsystemDescriptor>

Constructors

XREnvironmentProbeSubsystem()

Constructs an XREnvironmentProbeSubsystem. Do not create this directly. Call Create on an XREnvironmentProbeSubsystemDescriptor obtained from the SubsystemManager.

Declaration

public XREnvironmentProbeSubsystem()

Properties

automaticPlacement

Specifies whether the AR session should automatically place environment probes in the scene.

Declaration

public bool automaticPlacement { get; set; }

Property Value

Type	Description
Boolean	true if automatic placement of environment probes is enabled. Otherwise, false.

Remarks

If both manual and automatic placement of environment probes are supported, manually placed environment probes may be specified via regardless of whether automatic placement is enabled or not.

Exceptions

Type	Condition
NotSupportedException	Thrown when setting this value to true for implementations that do not support automatic placement.

environmentTextureHDR

Specifies whether the environment textures should be returned as HDR textures.

Declaration

public bool environmentTextureHDR { get; set; }

Property Value

Type	Description
Boolean	true if the environment textures should be returned as HDR textures. Otherwise, false.

Methods

CreateProvider()

Must create an implementation of XREnvironmentProbeSubsystem.Provider, the provider-specific implementation of this subsystem.

Declaration

protected abstract XREnvironmentProbeSubsystem.Provider CreateProvider()

Returns

Type	Description
XREnvironmentProbeSubsystem.Provider

GetChanges(Allocator)

Declaration

public override TrackableChanges<XREnvironmentProbe> GetChanges(Allocator allocator)

Parameters

Type	Name	Description
Allocator	allocator

Returns

Type	Description
TrackableChanges<XREnvironmentProbe>

Overrides

UnityEngine.XR.ARSubsystems.TrackingSubsystem<UnityEngine.XR.ARSubsystems.XREnvironmentProbe, UnityEngine.XR.ARSubsystems.XREnvironmentProbeSubsystemDescriptor>.GetChanges(Allocator)

OnDestroyed()

Destroys the subsystem and any internal state.

Declaration

protected override sealed void OnDestroyed()

Overrides

UnityEngine.XR.ARSubsystems.XRSubsystem<UnityEngine.XR.ARSubsystems.XREnvironmentProbeSubsystemDescriptor>.OnDestroyed()

OnStart()

Starts the subsystem. If automaticPlacement is true, environment probes will be created automatically.

Declaration

protected override sealed void OnStart()

Overrides

UnityEngine.XR.ARSubsystems.XRSubsystem<UnityEngine.XR.ARSubsystems.XREnvironmentProbeSubsystemDescriptor>.OnStart()

OnStop()

Stops the subsystem. This does not remove existing environment probes, but it stops automatically placing them, and manually placed probes will not be updated until OnStart() is called again.

Declaration

protected override sealed void OnStop()

Overrides

UnityEngine.XR.ARSubsystems.XRSubsystem<UnityEngine.XR.ARSubsystems.XREnvironmentProbeSubsystemDescriptor>.OnStop()

Register(XREnvironmentProbeSubsystemCinfo)

Registers a subsystem implementation based on the given subystem parameters.

Declaration

public static bool Register(XREnvironmentProbeSubsystemCinfo environmentProbeSubsystemCinfo)

Parameters

Type	Name	Description
XREnvironmentProbeSubsystemCinfo	environmentProbeSubsystemCinfo	The parameters defining the environment probe functionality implemented by the subsystem provider.

Returns

Type	Description
Boolean	true if the subsystem implementation is registered. Otherwise, false.

Exceptions

Type	Condition
ArgumentException	Thrown when the values specified in the environmentProbeSubsystemCinfo parameter are invalid. Typically, this will occur if id is null or empty if implementationType is null if implementationType does not derive from the XREnvironmentProbeSubsystem class

RemoveEnvironmentProbe(TrackableId)

Asynchronously removes the environment probe matching the trackable ID from the AR session.

Declaration

public bool RemoveEnvironmentProbe(TrackableId trackableId)

Parameters

Type	Name	Description
TrackableId	trackableId	Trackable ID of the environment probe to be removed from the AR session.

Returns

Type	Description
Boolean	true if the environment probe is found in the current AR session and will be removed. Otherwise, false.

Remarks

RemoveEnvironmentProbe may be used to remove both manually-placed and automatically-placed environment probes if the implementation supports such removals, as indicated by the descriptor properties supportsRemovalOfManual and supportsRemovalOfAutomatic.

Exceptions

Type	Condition
InvalidOperationException	Thrown when the environment probe subsystem is not running and this method is called to an add environment probe.
NotSupportedException	Thrown for platforms that do not support removal of the type of environment probe.

TryAddEnvironmentProbe(Pose, Vector3, Vector3, out XREnvironmentProbe)

Tries to create an environment probe.

Declaration

public bool TryAddEnvironmentProbe(Pose pose, Vector3 scale, Vector3 size, out XREnvironmentProbe environmentProbe)

Parameters

Type	Name	Description
Pose	pose	The position and rotation at which to create the environment probe.
Vector3	scale	The scale at which to create the environment probe.
Vector3	size	The size (dimensions) of the environment probe to create.
XREnvironmentProbe	environmentProbe	If successful, populated with the newly created environment probe. Otherwise, it will contain default values.

Returns

Type	Description
Boolean	true if the environment probe was successfully added, otherwise false.

Exceptions

Type	Condition
InvalidOperationException	Thrown when the environment probe subsystem is not running and this method is called to an add environment probe.
NotSupportedException	Thrown for platforms that do not support manual placement of environment probes.
