Syntax

public abstract class Provider : SubsystemProvider<XRAnchorSubsystem>

Methods

GetChanges(XRAnchor, Allocator)

Invoked to get the changes to anchors (added, updated, and removed) since the last call to GetChanges(XRAnchor, Allocator).

Declaration

public abstract TrackableChanges<XRAnchor> GetChanges(XRAnchor defaultAnchor, Allocator allocator)

Parameters

Type	Name	Description
XRAnchor	defaultAnchor	The default anchor. This should be used to initialize the returned NativeArrays for backwards compatibility. See TrackableChanges(Void*, Int32, Void*, Int32, Void*, Int32, T, Int32, Allocator).
Unity.Collections.Allocator	allocator	An allocator to use for the NativeArrays in TrackableChanges<T>.

Returns

Type	Description
TrackableChanges<XRAnchor>	Changes since the last call to GetChanges(XRAnchor, Allocator).

TryAddAnchor(Pose, out XRAnchor)

Should create a new anchor with the provided pose.

Declaration

public virtual bool TryAddAnchor(Pose pose, out XRAnchor anchor)

Parameters

Type	Name	Description
UnityEngine.Pose	pose	The pose, in session space, of the new anchor.
XRAnchor	anchor	The new anchor. Must be valid only if this method returns true.

Returns

Type	Description
Boolean	Should return true if the new anchor was added, otherwise false.

TryAttachAnchor(TrackableId, Pose, out XRAnchor)

Should create a new anchor "attached" to the trackable with id trackableToAffix. The behavior of the anchor depends on the type of trackable to which this anchor is attached and might be implementation-defined.

Declaration

public virtual bool TryAttachAnchor(TrackableId trackableToAffix, Pose pose, out XRAnchor anchor)

Parameters

Type	Name	Description
TrackableId	trackableToAffix	The id of the trackable to which to attach.
UnityEngine.Pose	pose	The pose, in session space, of the anchor to create.
XRAnchor	anchor	The new anchor. Must be valid only if this method returns true.

Returns

Type	Description
Boolean	true if the new anchor was added, otherwise false.

TryRemoveAnchor(TrackableId)

Should remove an existing anchor with TrackableId anchorId.

Declaration

public virtual bool TryRemoveAnchor(TrackableId anchorId)

Parameters

Type	Name	Description
TrackableId	anchorId	The id of an existing anchor to remove.

Returns

Type	Description
Boolean	Should return true if the anchor was removed, otherwise false. If the anchor does not exist, return false.
