Session History

Any session starts with the user sending the current scene file to the server.
Because modifying that scene and reloading it every time for everyone is inefficient and difficult, we use a History system.

This system builds on the initial data provided by the user.
You can receive the initial data from a session by calling:

Session session = ...;
session.GetInitialSceneData();

Any changes made during the session are saved as individual history objects.

Session session = ...;
List<History> history = session.GetAllHistory();  

You can see a 'History' as a 'Change'

Examples of 'History'

ObjectDestroyedHistory

A specific object was destroyed

TransformChangeHistory

moving, scaling or rotating an specific object

Joining and Catchup

Whenever a new user joins the session, session.SendHistory() gets called automatically.
This will send all changes made before the user joined, to the user.

Whenever a user makes new history, all users will get send this history aswell to keep them up to date.
