External DB and Custom Login

Postby Prefix » 21 Oct 2011, 02:38

Hello all, and thank you for reading and responding in advance. I've used the default login that SFS2x had in place for the tutorial FPS. Ive tweaked it a little and it worked well.

I recently expanded on this to create an external Database and so on. I've read the tutorials, how to's and utilized this Tutorial....

Recipe #1 — Custom login with database:

Since then, there's been some hardships and bugs and tweaking to get it workable. Ive finally gotten down to... pressing play on Unity, getting to a login screen. Typing in the name & password, IP and port. Click on Login, and then i get the following messages. I've looked through script after script and have no clue as to what im looking for, or where exactly the error is occuring.

So in short, it "hangs" on ... Sending login Request, approx 20-30 sec... Then finishes with ... OnConnectionLost.

Can you post the part of the script where you make the connection and all the callbacks please.
Are you processing the events that come back from SFS ?

My apologies, im just getting a grasp on the concept of this stuff. If you need more info, just lemme know in a little more detail what you need. Im still a begginer with this stuff :)

Thanks....

This is the LoginEventHandler

Your not making the connection at all in the client.
In your start function your should call a connect and the addlisteners function.

Ok. Could you please help me out with how this is supposed to be structured...

The client side handles the GUI and the entry login info. That info is then passed to the smartfoxserver (LoginEventHandler script)... LoginEventHandler script should be listening for the info that I have sent via client side GUI. Once Smartfox server has obtained (listened) for the information, it then sends that info to the "database" to do a "crosscheck" of username and password. Once it clears the login and password, the LoginEventHandler should now do a hand-off to the ZoneEventHandler?

Im confused as to what is supposed to be happening.

Thanks

client connects, zone extension sends to the logineventhandler, once allowed the connection becomes a client and gets sent to the joinzonehandler.
In the joinzone you can create rooms and send the connection to the room extension.

Checking the picture from the server log, there are no bound sockets!

I bet you put the wrong IP in the server config so the server isnt listening on any ports
