we're doing a videogame, and we have setted a procedure to create rooms server side.
Now our rooms are created when a player create a clan, and when he has created a clan, we generate a clan room.
When all the members of the clan are disconnected we destroy the room of the clan.
We need this to doing a chat group.
Now to recreate the room we have think to do this.
When a member is login, we research into the database if he has a clan, and then create the clan room if room is not active.
But i have problem to write the procedure server side.
I post my code to show what i need
Code: Select all
public class LoginEventHandler extends BaseServerEventHandler {

}
i have problem because the method createRoom needs a user, on the other handler is different because i call the execution when a user is logged in.
How can i do my procedure on my explaination??
Thanks to all for the help
