Namespace: UnityEngine.XR.ARSubsystems

Syntax

public abstract class XRRaycastSubsystem : XRSubsystem<XRRaycastSubsystemDescriptor>, ISubsystem

Remarks

This abstract class should be implemented by an XR provider and instantiated using the SubsystemManager to enumerate the available XRRaycastSubsystemDescriptors.

Constructors

XRRaycastSubsystem()

Constructor. Do not invoke directly; use the SubsystemManager to enumerate the available XRRaycastSubsystemDescriptors and call Create on the desired descriptor.

Declaration

public XRRaycastSubsystem()

Methods

CreateProvider()

Should return an instance of XRRaycastSubsystem.Provider.

Declaration

protected abstract XRRaycastSubsystem.Provider CreateProvider()

Returns

Type	Description
XRRaycastSubsystem.Provider	The interface to the implementation-specific provider.

OnDestroyed()

Destroys the subsystem.

Declaration

protected override sealed void OnDestroyed()

Overrides

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

OnStart()

Starts the subsystem.

Declaration

protected override sealed void OnStart()

Overrides

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

OnStop()

Stops the subsystem.

Declaration

protected override sealed void OnStop()

Overrides

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

Raycast(Ray, TrackableType, Allocator)

Casts ray against trackables specified with trackableTypeMask.

Declaration

public NativeArray<XRRaycastHit> Raycast(Ray ray, TrackableType trackableTypeMask, Allocator allocator)

Parameters

Type	Name	Description
Ray	ray	A ray in session space.
TrackableType	trackableTypeMask	The types of trackables to test for ray intersections.
Allocator	allocator	The Allocator used to allocate the returned NativeArray.

Returns

Type	Description
NativeArray<XRRaycastHit>	A NativeArray of all the resulting ray intersections.

Raycast(Vector2, TrackableType, Allocator)

Casts a ray originating from screenPoint against trackables specified with trackableTypeMask.

Declaration

public NativeArray<XRRaycastHit> Raycast(Vector2 screenPoint, TrackableType trackableTypeMask, Allocator allocator)

Parameters

Type	Name	Description
Vector2	screenPoint	A point on the screen in normalized screen coordinates (0, 0) - (1, 1)
TrackableType	trackableTypeMask	The types of trackables to test for ray intersections.
Allocator	allocator	The Allocator used to allocate the returned NativeArray.

Returns

Type	Description
NativeArray<XRRaycastHit>	A NativeArray of all the resulting ray intersections.
