|nodeStates||A list that is populated with XRNodeState objects.|
Describes all currently connected XRNodes and provides available tracking states for each.
Use this method to acquire all the currently available XR input Nodes, as an alternative to handling the node events InputTracking.nodeAdded and InputTracking.nodeRemoved. The contents of
nodeStates list will be cleared and replaced with fresh data.
Not all XR platforms provide complete tracking data. Use the methods XRNodeState.TryGetPosition, XRNodeState.TryGetRotation, etc. to read the data if it's available.
