Properties

boundingBoxPrefab

Get or set the prefab to instantiate for each detected 3D bounding box. Can be null.

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

gameObjectName

The name to be used for the instantiated GameObject whenever a new 3D bounding box is detected.

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

Methods

Awake()

Saves a reference to the XR Origin component and initializes a BoundingBoxRaycaster with a collection of bounding box trackables.

Declaration
protected override void Awake()
Overrides

GetPrefab()

Get the prefab to instantiate for each detected 3D bounding box. Can be null.

Declaration
protected override GameObject GetPrefab()
Returns
Type Description
GameObject

The Prefab which will be instantiated for each ARBoundingBox.
Overrides

OnDisable()

Invoked when this component is disabled. Used to unregister with the ARRaycastManager.

Declaration
protected override void OnDisable()
Overrides

OnEnable()

Invoked when Unity enables this MonoBehaviour. Used to register with the ARRaycastManager.

Declaration
protected override void OnEnable()
Overrides

Raycast(Ray, TrackableType, Allocator)

Performs a raycast against all currently tracked 3D bounding boxes.

Declaration
public NativeArray<XRRaycastHit> Raycast(Ray ray, TrackableType trackableTypeMask, Allocator allocator)
Parameters
Type Name Description
Ray ray

The ray, in Unity world space, to cast.
TrackableType trackableTypeMask

A mask of raycast types to perform.
Allocator allocator

The Allocator to use when creating the returned NativeArray.
Returns
Type Description
NativeArray<XRRaycastHit>

A new NativeArray of raycast results allocated with allocator. The caller owns the memory and is responsible for calling Dispose on the NativeArray.

TryGetBoundingBox(TrackableId, out ARBoundingBox)

Attempt to retrieve an existing ARBoundingBox by trackableId.

Declaration
public bool TryGetBoundingBox(TrackableId trackableId, out ARBoundingBox arBoundingBox)
Parameters
Type Name Description
TrackableId trackableId

The TrackableId of the bounding box to retrieve.
ARBoundingBox arBoundingBox

The output bounding box, if this method returns true.
Returns
Type Description
bool

true if a bounding box exists with the given trackableId. Otherwise, false.
