ARGeospatialAnchor
The ARGeospatialAnchor is an ARCore Extensions object that provides a similar service to AR Foundation's ARAnchor as an anchor for game objects in your scene.
It is created at the specified geodetic location and orientation relative to the Earth.
When the game object containing the ARGeospatialAnchor component is destroyed, the underlying native object will be detached and the resource will be released.
Gets the TrackingState associated with this Geospatial Anchor.
Public functions
OnDestroy
voidOnDestroy()
When the game object containing the ARGeospatialAnchor component is destroyed, the underlying native object will be detached and the resource will be released.
