Class XRReferenceObjectLibrary

A container for reference objects. A reference object represents a 3D scan of a real object that can be recognized in the environment. A XRObjectTrackingSubsystem will search for objects based on the contents of a XRReferenceObjectLibrary.

Declaration

public int count { get; }

Property Value

Type	Description
Int32

guid

A Guid associated with this reference library. The Guid is used to uniquely identify this library at runtime.

Declaration

public Guid guid { get; }

Property Value

Type	Description
Guid

Item[Int32]

Get a reference object by index.

Declaration

public XRReferenceObject this[int index] { get; }

Parameters

Type	Name	Description
Int32	index	The index in the array of reference objects. Must be greater than or equal to 0 and less than count.

Property Value

Type	Description
XRReferenceObject	The XRReferenceObject at index.

Methods

GetEnumerator()

Gets an enumerator which can be used to iterate over the reference objects in this library.

Declaration

public List<XRReferenceObject>.Enumerator GetEnumerator()

Returns

Type	Description
List.Enumerator<>	An IEnumerator which can be used to iterate over the reference objects in the library.

Examples

This examples iterates over the reference objects contained in the library.

XRReferenceObjectLibrary library = ...
foreach (var referenceObject in library)
    Debug.LogFormat("Reference object guid: {0}", referenceObject.guid);

indexOf(XRReferenceObject)

Get the index of referenceObject in the object library.

Declaration

public int indexOf(XRReferenceObject referenceObject)

Parameters

Type	Name	Description
XRReferenceObject	referenceObject	The XRReferenceObject to find.

Returns

Type	Description
Int32	The zero-based index of the referenceObject, or -1 if not found.
