STUB article, some incomplete notes:

multiplayer modes

Vegastrike Multiplayer supports 2 modes :

  • deathmatch, for lan instant action. vegastrike multiplayer dialog : "Independent Server"
  • mmo (massive multiplayer online). vegastrike multiplayer dialog : "Online Account Server"

Deathmatch mode

by default a system with no jumps and just 1 planet for buying stuff

MMO mode

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
  • mmo-mode : 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

mmo mode : 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)
