Hi! Welcome to have a view of this project.

This project contains anything that I have helped with my fellows' project, so most of them are about HoloLens/UWP development. I recommend you to download Unity pages instead of git clone or downloading zip file, and please install MixedRealityToolkit-Unity(MRTK) before you import packages(URL:https://github.com/Microsoft/MixedRealityToolkit-Unity)

This project would be updated on a monthly basis. ;-)
Good luck!

Same from the default function - WorldAnchor, this solution is trying to duplicate the WorldAnchor function which extracts Object name, positions.
For a reason, considering the instantiated GameOject newly cannot be saved into WorldAnchorStore.cs correctly, this process could be utilized to take the place of WorldAnchor.

This project is using XML to save the position information by the GameController.cs.
Those objects that you want to save should add a PrefabActor.cs component. Data would be written into Data/actors.xml, and as I mentioned before because it is using two different platforms (UnityEditor and UWP), so the PATH setting is also included.
