Development:Network:process login

MMO mode is meant for more persistent gameplay than deathmatch mode, for this a accountserver is needed.

• to join an MMO Server, select "Online Account Server" under vegastrike multiplayer dialog
• at the time of writing there are no public MMO servers available (see forum for tharin server, in case it gets back online someday), but it can be run locally:
• see "HOWTO: Setup and configure vegaserver." http://forums.vega-strike.org/viewtopic.php?f=37&t=17701

STUB article, some incomplete notes:

• instead of logging into the game server directly, the game first logs into the account server via http request
• the account server replies via http with success/failure status, and in case of success the ip and port of the gameserver to log in to

account server protocol

• the reply of the account server (http answer payload) is plaintext using the format <number>SPACE

• see also data/cgi-accountserver/accountserver.py
• first char is message type :

• ACCT_LOGIN='l'
• ACCT_LOGIN_DATA='d',(field username),(field warning),(field serverip),(field serverport) -- sent by server when login is accepted
• ACCT_LOGIN_ERROR='e'
• ACCT_LOGIN_ALREADY='f'
• ACCT_LOGIN_NEW='n'
• ACCT_LOGIN_ACCEPT='a'
• ACCT_LOGOUT='o'
• ACCT_SAVE_LOGOUT='S'
• ACCT_RESYNC='r'
• ACCT_SAVE='s'
• ACCT_NEWCHAR='c'
• ACCT_NEWSUBSCRIBE='u'
• ACCT_SUCCESS='!'

login request

• client sends http "d6 asdasd6 asdasd" (ACCT_LOGIN_DATA, username=asdasd password=asdasd)
• server sends http "d6 asdasd0 9 127.0.0.14 6777" (ACCT_LOGIN_DATA, username=asdasd, warning=emptystring, serverip=127.0.0.1, port=6777)
