Synchronizing client/server states

Is there a provided way to synchronize the game state between the client and the server, or is this something that is implemented by the game developer?

Right now, this is something implemented by the game developer and in general is pretty specific to the type of engine being created… maybe with large categories of similarity.

There may be some updates to this status in the future. There is currently the deprecated sync service that does not work with the new API but I think someone has plans of replacing that with a fully-functioning and better version at some point.

Yes there will be a built-in sync system. Right now it is a work-in-progress.
