Struct XRRaycastHit

Represents the intersection of a raycast with a trackable.

Namespace: UnityEngine.XR.ARSubsystems
Syntax
public struct XRRaycastHit : IEquatable<XRRaycastHit>

Constructors

XRRaycastHit(TrackableId, Pose, Single, TrackableType)

Constructs an XRRaycastHit.

Declaration
public XRRaycastHit(TrackableId trackableId, Pose pose, float distance, TrackableType hitType)
Parameters
Type Name Description
TrackableId trackableId

The TrackableId of the trackable which was hit.
Pose pose

The session-space Pose of the intersection.
Single distance

The session-space distance from the raycast origin to the intersection point.
TrackableType hitType

The type(s) of trackables which were hit by the ray.

Properties

defaultValue

A default-initialized raycast hit. This may be different from a zero-initialized raycast hit.

Declaration
public static readonly XRRaycastHit defaultValue { get; }
Property Value
Type Description
XRRaycastHit

distance

The session-space distance from the raycast origin to the intersection point.

Declaration
public float distance { get; set; }
Property Value
Type Description
Single

hitType

The type(s) of trackables which were hit by the ray.

Declaration
public TrackableType hitType { get; set; }
Property Value
Type Description
TrackableType

pose

The session-space Pose of the intersection.

Declaration
public Pose pose { get; set; }
Property Value
Type Description
Pose

trackableId

The TrackableId of the trackable which was hit. This may be invalidId as not all trackables have ids, e.g., feature points.

Declaration
public TrackableId trackableId { get; set; }
Property Value
Type Description
TrackableId

Methods

Equals(Object)

Tests for equality.

Declaration
public override bool Equals(object obj)
Parameters
Type Name Description
Object obj

The object to compare against.
Returns
Type Description
Boolean

True if obj is of type XRRaycastHit and Equals(XRRaycastHit) also returns true; otherwise false.
Overrides

Equals(XRRaycastHit)

Tests for equality.

Declaration
public bool Equals(XRRaycastHit other)
Parameters
Type Name Description
XRRaycastHit other

The other XRRaycastHit to compare against.
Returns
Type Description
Boolean

True if every field in other is equal to this XRRaycastHit, otherwise false.

GetHashCode()

Generates a hash suitable for use with containers like HashSet and Dictionary.

Declaration
public override int GetHashCode()
Returns
Type Description
Int32

A hash code generated from this object's fields.
Overrides

Operators

Equality(XRRaycastHit, XRRaycastHit)

Tests for equality. Same as Equals(XRRaycastHit).

Declaration
public static bool operator ==(XRRaycastHit lhs, XRRaycastHit rhs)
Parameters
Type Name Description
XRRaycastHit lhs

The left-hand side of the comparison.
XRRaycastHit rhs

The right-hand side of the comparison.
Returns
Type Description
Boolean

True if lhs is equal to rhs, otherwise false.

Inequality(XRRaycastHit, XRRaycastHit)

Tests for inequality. Same as !Equals(XRRaycastHit).

Declaration
public static bool operator !=(XRRaycastHit lhs, XRRaycastHit rhs)
Parameters
Type Name Description
XRRaycastHit lhs

The left-hand side of the comparison.
XRRaycastHit rhs

The right-hand side of the comparison.
Returns
Type Description
Boolean

True if lhs is not equal to rhs, otherwise false.
