Properties

automaticPlacement

A property of the environment probe subsystem that, if enabled, automatically generates environment probes for the scene. This method is obsolete. Use automaticPlacementRequested or automaticPlacementEnabled instead.

Declaration
[Obsolete("Use automaticPlacementRequested or automaticPlacementEnabled instead. (2020-01-16)")]
public bool automaticPlacement { get; set; }
Property Value
Type Description
bool

true if automatic environment probe placement is enabled. Otherwise, false.

automaticPlacementEnabled

true if automatic placement is enabled on the subsystem.

Declaration
public bool automaticPlacementEnabled { get; }
Property Value
Type Description
bool

automaticPlacementRequested

If enabled, requests automatic generation of environment probes for the scene.

Declaration
public bool automaticPlacementRequested { get; set; }
Property Value
Type Description
bool

true if automatic environment probe placement is requested. Otherwise, false.

debugPrefab

Specifies a debug Prefab that will be attached to all environment probes.

Declaration
public GameObject debugPrefab { get; set; }
Property Value
Type Description
GameObject

A debug Prefab that will be attached to all environment probes.
Remarks

Setting a debug Prefab allows for these environment probes to be more readily visualized but is not required for normal operation of this manager. This script will automatically create reflection probes for all environment probes reported by the XREnvironmentProbeSubsystem.

environmentTextureFilterMode

Specifies the texture filter mode to be used with the environment texture.

Declaration
public FilterMode environmentTextureFilterMode { get; set; }
Property Value
Type Description
FilterMode

The texture filter mode to be used with the environment texture.

environmentTextureHDR

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

Declaration
[Obsolete("Use environmentTextureHDRRequested or environmentTextureHDREnabled instead. (2020-01-16)")]
public bool environmentTextureHDR { get; set; }
Property Value
Type Description
bool

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

environmentTextureHDREnabled

Queries whether environment textures will be provided with high dynamic range.

Declaration
public bool environmentTextureHDREnabled { get; }
Property Value
Type Description
bool

environmentTextureHDRRequested

Get or set whether high dynamic range environment textures are requested.

Declaration
public bool environmentTextureHDRRequested { get; set; }
Property Value
Type Description
bool

gameObjectName

The name of the GameObject for each instantiated AREnvironmentProbe.

Declaration
protected override string gameObjectName { get; }
Property Value
Type Description
string
Overrides

Methods

AddEnvironmentProbe(Pose, Vector3, Vector3)

Creates a new environment probe at pose with scale and size if supported by the subsystem. Use the descriptor's supportsManualPlacement property to determine support for this feature. If successful, a new GameObject with an AREnvironmentProbe is created immediately; however, the provider might not report the environment probe as added until a future frame. Check the status of the probe by inspecting its pending property.

Declaration
[Obsolete("Add an environment probe using AddComponent<AREnvironmentProbe>(). (2020-10-06)")]
public AREnvironmentProbe AddEnvironmentProbe(Pose pose, Vector3 scale, Vector3 size)
Parameters
Type Name Description
Pose pose

The position and rotation at which to create the new environment probe.
Vector3 scale

The scale of the new environment probe.
Vector3 size

The size (dimensions) of the new environment probe.
Returns
Type Description
AREnvironmentProbe

A new AREnvironmentProbe if successful, otherwise null.
Exceptions
Type Condition
InvalidOperationException

Thrown if this manager is not enabled
InvalidOperationException

Thrown if this manager has no subsystem.
NotSupportedException

Thrown if manual placement is not supported by this subsystem. Check for support on the descriptor's supportsManualPlacement property.

GetEnvironmentProbe(TrackableId)

Attempts to find the environment probe matching the trackable ID currently in the scene.

Declaration
public AREnvironmentProbe GetEnvironmentProbe(TrackableId trackableId)
Parameters
Type Name Description
TrackableId trackableId

The trackable ID of an environment probe to search for.
Returns
Type Description
AREnvironmentProbe

Environment probe in the scene matching the trackableId, or null if no matching environment probe is found.

GetPrefab()

Gets the prefab that should be instantiated for each AREnvironmentProbe. May be null.

Declaration
protected override GameObject GetPrefab()
Returns
Type Description
GameObject

The prefab that should be instantiated for each AREnvironmentProbe.
Overrides

OnBeforeStart()

Enables the environment probe functionality by registering listeners for the environment probe events, if the XREnvironmentProbeSubsystem exists, and enabling environment probes in the AR subsystem manager.

Declaration
protected override void OnBeforeStart()
Overrides

OnCreateTrackable(AREnvironmentProbe)

Invoked when an AREnvironmentProbe is created.

Declaration
protected override void OnCreateTrackable(AREnvironmentProbe probe)
Parameters
Type Name Description
AREnvironmentProbe probe

The AREnvironmentProbe that was just created.
Overrides

OnDestroy()

Destroys any game objects created by this environment probe manager for each environment probe, and clears the mapping of environment probes.

Declaration
protected override void OnDestroy()
Overrides

OnTrackablesChanged(List<AREnvironmentProbe>, List<AREnvironmentProbe>, List<AREnvironmentProbe>)

Invoked when the base class detects trackable changes.

Declaration
protected override void OnTrackablesChanged(List<AREnvironmentProbe> added, List<AREnvironmentProbe> updated, List<AREnvironmentProbe> removed)
Parameters
Type Name Description
List<AREnvironmentProbe> added

The list of added AREnvironmentProbe.
List<AREnvironmentProbe> updated

The list of updated AREnvironmentProbe.
List<AREnvironmentProbe> removed

The list of removed AREnvironmentProbe.
Overrides

RemoveEnvironmentProbe(AREnvironmentProbe)

Remove an existing environment probe. Support for this feature is provider-specific. Check for support with the descriptor's supportsRemovalOfManual and supportsRemovalOfAutomatic properties.

Declaration
[Obsolete("Call Destroy() on the AREnvironmentProbe component to remove it. (2020-10-06)")]
public bool RemoveEnvironmentProbe(AREnvironmentProbe probe)
Parameters
Type Name Description
AREnvironmentProbe probe

The environment probe to remove
Returns
Type Description
bool

true if the environment probe was removed, otherwise false.
Exceptions
Type Condition
InvalidOperationException

Thrown if this manager is not enabled.
InvalidOperationException

Thrown if subsystem is null.
ArgumentNullException

Thrown if probe is null.
InvalidOperationException

Thrown if the environment probe was manually placed, but removal of manually placed probes is not supported. You can check for this case with placementType and the descriptor's 'supportsRemovalOfManual` property.
InvalidOperationException

Thrown if the environment probe was automatically placed, but removal of automatically placed probes is not supported. You can check for this case with placementType and the descriptor's supportsRemovalOfAutomatic property.
