OpenXRMarkerTracker

public OpenXRMarkerTracker();

Creates a caller-owned RefCounted tracker without starting OpenXR, registering with XRServer or detecting anything. Base state is Paused, category Anchor, entity/context RIDs empty. Real applications normally use the borrowed provider-registered tracker rather than a synthetic resource. Release your own instance after removing owned references/registration.

public Vector2 BoundsSize { get; set; }

Stored marker size, initially Vector2.Zero. The setter only stores Vector2; it starts no camera, changes no tracker pose and creates no mesh/collider. Real size comes from the runtime; synthetic tracker metadata proves no detection.

public uint MarkerId { get; set; }

Numeric uint marker ID, initially 0. Match ArUco/AprilTag with type and dictionary; neither a persistence UUID nor QR text. The setter only stores metadata; zero alone is not an error.

public OpenXRSpatialComponentMarkerList.MarkerType MarkerType { get; set; }

Marker type, initially Unknown. Runtime data can represent QR, Micro QR, ArUco or AprilTag; check support for each type. The setter changes metadata only; it starts no detector and selects no dictionary.

public Vector2 GetBoundsSize();

Stored marker size, initially Vector2.Zero. The setter only stores Vector2; it starts no camera, changes no tracker pose and creates no mesh/collider. Real size comes from the runtime; synthetic tracker metadata proves no detection.

public Variant GetMarkerData();

Variant payload, initially Nil. QR/Micro QR provider data can be String or PackedByteArray; C# SetMarkerData can store other Variants too, so check VariantType before reading. Map allowed identifiers rather than treating arbitrary text as a path/code. The setter decodes no marker and resets the internal buffer ID.

public uint GetMarkerId();

Numeric uint marker ID, initially 0. Match ArUco/AprilTag with type and dictionary; neither a persistence UUID nor QR text. The setter only stores metadata; zero alone is not an error.

public OpenXRSpatialComponentMarkerList.MarkerType GetMarkerType();

Marker type, initially Unknown. Runtime data can represent QR, Micro QR, ArUco or AprilTag; check support for each type. The setter changes metadata only; it starts no detector and selects no dictionary.

public void SetBoundsSize(Vector2 boundsSize);

Stored marker size, initially Vector2.Zero. The setter only stores Vector2; it starts no camera, changes no tracker pose and creates no mesh/collider. Real size comes from the runtime; synthetic tracker metadata proves no detection.

public void SetMarkerData(Variant markerData);

Variant payload, initially Nil. QR/Micro QR provider data can be String or PackedByteArray; C# SetMarkerData can store other Variants too, so check VariantType before reading. Map allowed identifiers rather than treating arbitrary text as a path/code. The setter decodes no marker and resets the internal buffer ID.

public void SetMarkerId(uint markerId);

Numeric uint marker ID, initially 0. Match ArUco/AprilTag with type and dictionary; neither a persistence UUID nor QR text. The setter only stores metadata; zero alone is not an error.

public void SetMarkerType(OpenXRSpatialComponentMarkerList.MarkerType markerType);

Marker type, initially Unknown. Runtime data can represent QR, Micro QR, ArUco or AprilTag; check support for each type. The setter changes metadata only; it starts no detector and selects no dictionary.
