Legacy:UT Server Query
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
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.
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
- Australia / NZ / Pacific
- Central, South America
Usual the server admin has not set their location, so it's usualy 0

GetInfo(); function in the game type for additions
Setting for the current game, the rules

The return sets of rules depends on the running game type.
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]]
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
This is a shorthand for
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
\ignored\ or something else.
This will return the value of the argument passed to it.
This works just like \level_property\ except it will return values of Level.Game
This will return a the value of a PlayerPawn variable, for each PlayerPawn on the server.
You can combine commands in a single query:
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.
