Legacy:UT Server Query
Contents
Introduction[edit]
UT makes use of the so called GameSpy Query Protocol to return status information to be used by the in-game browser or 3rd party server browsers.
The server query system uses. just like the game protocol. Wikipedia:UDP. This is an unreliable protocol, meaning packets might get lost during transmission.
UT listens on the port gameport+1 (7778 by default) for GameSpy Query commands.
Below is a list of commands that are accepted by UT. The field seperator is the backslash. The returns always consists out of a set of \name\value elements.
Requests often end with \queryid\[number.number]\final\, if you encounter the \final\ the last piece of the request has been send. But don't rely on the \final\. It may not be received at all.
Note: I've broken down the replies for readability. The actual replies do not have newlines in them.
Query commands[edit]
\basic\[edit]
This returns basic server information, mainly for recognition.
\gamename\[game name] \gamever\[Level.EngineVersion] \minnetver\[Level.MinNetVersion] \location\[Level.Game.GameReplicationInfo.Region]
The game name is always ut for UT
The regional location is one of the following:
- No Region Specified (any Region)
- Southeast US
- Western US
- Midwest US
- Northwest US, West Canada
- Northeast US, East Canada
- United Kingdom
- Continental Europe
- Central Asia, Middle East
- Southeast Asia, Pacific
- Africa
- Australia / NZ / Pacific
- Central, South America
Usual the server admin has not set their location, so it's usualy 0
\info\[edit]
Information about the current game running on the server
\hostname\[Level.Game.GameReplicationInfo.ServerName] \hostport\[game port] \maptitle\[Level.title] \mapname\[file name without extention] \gametype\[Level.Game.Class] \numplayers\[Level.Game.NumPlayers] \maxplayers\[Level.Game.MaxPlayers] \gamemode\openplaying \gamever\[Level.EngineVersion] \minnetver\[Level.MinNetVersion] \worldlog\[world logging enabled and working] \wantworldlog\[world logging enabled] ...
Game mode is always openplaying
More replies can be added here by various game types, this should not contain game type settings. Check the GetInfo(); function in the game type for additions
\rules\[edit]
Setting for the current game, the rules
\mutators\[comma seperated list] \listenserver\[is a listen server/non dedicated server] \password\[true or false] ... \AdminName\[Level.Game.GameReplicationInfo.AdminName] \AdminEMail\[Level.Game.GameReplicationInfo.AdminEmail]
The return sets of rules depends on the running game type.
Check the GetRules(); function in the game type for additions.
A CTFGame would return the following additional values:
\timelimit\[Timelimit] \goalteamscore\[GoalTeamScore] \minplayers\[MinPlayers] \changelevels\[bChangeLevels] \maxteams\[MaxTeams] \balanceteams\[bBalanceTeams] \playerbalanceteams\[bPlayersBalanceTeams] \friendlyfire\[percentage] \gamestype\[Turbo or Hardcore or Classic] \botskill\[class'ChallengeBotInfo'.default.Skills[Difficulty]]
\players\[edit]
Returns information about each player on the server. The # in the names below is the player number
\player_#\[PlayerReplicationInfo.PlayerName] \frags_#\[PlayerReplicationInfo.Score] \ping_#\[player ping] \team_#\[PlayerReplicationInfo.Team] \mesh_#\[Player mesh] \skin_#\[Player skin] \face_#\[Player face] \ngsecret_#\[bot or true or false]
ngsecret defines if the player has a ngStats password set
\status\[edit]
This is a shorthand for \basic\\info\\rules\\players\
\echo\[edit]
This command requires a argument, the argument will be returned.
For example when you send:
\echo\this is a test
the following will be returned:
\echo_replay\this is a test
Note: the name of the reply can be diffirent, it could be \echo\, \echo_reply\, \ignored\ or something else.
\level_property\[edit]
This will return the value of the argument passed to it.
For example:
\level_property\Title
will return
\Title\[Level.Title]
\game_property\[edit]
This works just like \level_property\ except it will return values of Level.Game
\player_property\[edit]
This will return a the value of a PlayerPawn variable, for each PlayerPawn on the server.
Tricks[edit]
You can combine commands in a single query:
\basic\\info\\rules\
But watch out, when the last command is invalid you might not get a single result. A nice trick to get around this problem is to always append \echo\something at the end.
This allows you to use 3rd party commands that might have been added by a mod.
