A simple way seems to do this seems to be by updating the virtual currency directly through the Game Manager (Player > Virtual currency), but it doesn't look like there's a way to update the client this way?
The usage here would be for example for customer support rewarding the player with X amount of X currency for whatever reason, so the initiation should be from the server and not the server. The server should just let the client know that their currency has been updated.
How could this be done? Thanks!
