AMRUKTrackable Class

Extends AActor
Represents a trackable object in the Mixed Reality Utility Kit. A trackable is a type of object that can be detected and tracked by the runtime, such as keyboards and QR codes. Unlike scene anchors, trackables can move dynamically and may become temporarily untracked if they cannot be seen by the device.
Trackables are instantiated and managed by UMRUKSubsystem. When a new trackable is detected, the subsystem creates an AMRUKTrackable actor and invokes the OnTrackableAdded event.

Constructors

AMRUKTrackable ( ObjectInitializer )
Signature 
AMRUKTrackable::AMRUKTrackable(const FObjectInitializer &ObjectInitializer)
Parameters
ObjectInitializer: const FObjectInitializer &

Fields

IsTracked : bool
Whether this trackable is currently being tracked. A trackable may become temporarily untracked if it cannot be seen by the device.
Signature 
bool AMRUKTrackable::IsTracked
MarkerPayloadBytes : TArray< uint8 >
The marker's payload as raw bytes. If this trackable is a marker (e.g., a QR Code), this property contains the raw payload bytes. Otherwise, the array is empty.
Signature 
TArray<uint8> AMRUKTrackable::MarkerPayloadBytes
MarkerPayloadString : FString
The marker's payload as a string. If this trackable is a marker (e.g., a QR Code) and its payload can be interpreted as a string, this property contains the decoded string. Otherwise, it is empty.
Signature 
FString AMRUKTrackable::MarkerPayloadString
The type of payload the trackable carries.
Signature 
EMRUKMarkerPayloadType AMRUKTrackable::PayloadType
PlaneBoundary2D : TArray< FVector2D >
If the trackable has a plane attached to it, this represents the boundary of it in local coordinate space.
Signature 
TArray<FVector2D> AMRUKTrackable::PlaneBoundary2D
PlaneBounds : FBox2D
If the trackable has a plane attached to it, this represents the bounds of that plane in local coordinate space.
Signature 
FBox2D AMRUKTrackable::PlaneBounds
TrackableType : EMRUKTrackableType
The type of this trackable (e.g., Keyboard, QRCode)
Signature 
EMRUKTrackableType AMRUKTrackable::TrackableType
VolumeBounds : FBox
If the trackable has a volume attached to it, this represents the bounds of that volume in local coordinate space.
Signature 
FBox AMRUKTrackable::VolumeBounds
