API reference
OVRMarkerPayload Struct
Extends IOVRAnchorComponent< OVRMarkerPayload >, IEquatable< OVRMarkerPayload >
(Obsolete) Represents a marker payload (QR Code) associated with an OVRAnchor.
Deprecated
The QR Code Detection API has moved to MRUK: https://developers.meta.com/horizon/documentation/unity/unity-mr-utility-kit-overview
Anchors with a payload support this component type. In order to access an anchor's payload, first get this component from the OVRAnchor, as in the following example:
void AccessPayload(OVRAnchor anchor) {
if (!anchor.TryGetComponent\<OVRMarkerPayload\>(out var payload)) {
Debug.LogError("Anchor does not have a payload component.");
return;
}
Debug.Log($"Anchor payload is of type {payload.PayloadType}.");
}
A OVRMarkerPayload can represent different types of data, indicated by the PayloadType property. If the type is a OVRMarkerPayloadType.StringQRCode, use AsString to get the payload as a System.String.
Public Statics
static readonly OVRMarkerPayload Null[Get]
A null representation of an OVRMarkerPayload.
Use this to compare with another component to determine whether it is null.
Properties
bool IsNull[Get]
Whether this object represents a valid anchor component.
bool IsEnabled[Get]
True if this component is enabled and no change to its enabled status is pending.
SpaceComponentType Type[Get]
ulong Handle[Get]
OVRMarkerPayloadType PayloadType[Get]
The payload type, e.g., string vs binary.
ArraySegment< byte > Bytes[Get]
A copy of the payload bytes.
This property creates a new copy of the payload bytes each time it is invoked. Use GetBytes to provide your own buffer.
int ByteCount[Get]
The number of bytes in the payload.
Member Functions
bool Equals
( OVRMarkerPayload other )
Compares this component for equality with other .
Parameters
other
The other component to compare with.
Returns
True if both components belong to the same OVRAnchor, otherwise false.
override bool Equals
( object obj )
Compares this component for equality with obj .
Parameters
obj
The object to compare with.
Returns
True if obj is an OVRMarkerPayload and Equals(OVRMarkerPayload) is true, otherwise false.
override int GetHashCode ( )
Gets a hashcode suitable for use in a Dictionary or HashSet.
Returns
A hashcode for this component.
override string ToString ( )
Gets a string representation of this component.
Returns
A string representation of this component.
string AsString ( )
Gets the payload as a string.
PayloadType must be OVRMarkerPayloadType.StringQRCode.
Returns
Returns the payload as a string.
Exceptions
InvalidOperationException
Thrown if PayloadType is not OVRMarkerPayloadType.StringQRCode
int GetBytes
( Span< byte > buffer )
Copies the payload bytes to buffer .
Use this method to copy the payload data into a byte array. buffer must be large enough to hold the data. Use ByteCount to create a buffer large enough to hold the payload data.
byte[] GetData(OVRMakerPayload payload)
{
var bytes = newbyte[payload.ByteCount];
var length = payload.GetBytes(bytes);
return bytes;
}
Parameters
buffer
A Span to write the payload data to.
Returns
Returns the number of bytes written to buffer .
Exceptions
ArgumentException
Thrown if buffer is less than ByteCount.
Static Member Functions
static bool operator==
( OVRMarkerPayload lhs,
OVRMarkerPayload rhs )
Compares two components for equality.
Parameters
lhs
The component to compare with rhs .
rhs
The component to compare with lhs .
Returns
True if both components belong to the same OVRAnchor, otherwise false.
static bool operator!=
( OVRMarkerPayload lhs,
OVRMarkerPayload rhs )
Compares two components for inequality.
Parameters
lhs
The component to compare with rhs .
rhs
The component to compare with lhs .
Returns
True if the components do not belong to the same OVRAnchor, otherwise false.
