UT :: Object >> Actor >> Info (UT) >> GameInfo (Package: Engine)

A GameInfo subclass contains the rules for a gametype. This includes timelimit, fraglimit, scoring, difficulty, game speed, allowed playerpawn classes, default inventory assignment, and if appropriate, team assignment and general bot behavior.

This is assigned to a map in the Level Properties window, under LevelInfo -> DefaultGameType.

The GameInfo for the current game can be retrieved from every actor in that game via Level.Game, but only on the server. GameInfo is not replicated to network clients; only GameReplicationInfo (UT) is.

See GameInfo for the UT200x version of this class.

Server query info


AdminLogin (PlayerPawn P, string Password) 
This function will allow a player to log in as the administrator if the password entered is correct. The function also broadcasts a notification message to the other players.
AdminLogout (PlayerPawn P) 
This function is called when a player leaves administrator mode. It ensures that the player is forced to "Walk", and kills them. There is code in there to preserve the players score when they die from logging out of admin mode but I'm sure it doesn't work in practice. – must check.
InitLogging ( ) 
Called from PostBeginPlay(). Logs more stuff than you can shake a big stick at. Calls functions on the WorldLog, Log, and LocalLog objects to do so.
InitGameReplicationInfo ( ) 
This function is responsible for placing the values of the attributes of the GameInfo class important to the client onto the GameReplicationInfo object.
string GetInfo ( ) 
Returns the status of the World log.
string GetRules ( ) 
This function builds up a description of the server from the list of mutators currently in use, the type of server (Listen or otherwise), and whether there is a password on the server or not.
int GetServerPort ( ) 
This functon returns the port the server is runing on by interrogating the level URL.
bool SetPause (bool bPause, PlayerPawn P) 
If the level can be paused then the player who paused the game is stored and the function returns true. If the game is not pausable then the function will return false.
LogGameParameters (StatLog StatLog) 
This function writes the general game parameters to the StatLog.
SetGameSpeed (float T) 
This function sets the game speed (but never below 0.1).
bool IsRelevant (Actor Other) 
This function is called from any Actor's PreBeginPlay(). If this function returns true the actor continues to exist. If the function returns false the actor is removed from the game. This function calls the AlwaysKeep() and IsRelevant() functions on any mutators within the game prior to checking actor difficulty levels and "odds of appearing" values. The function also counts the number of remaining SecretGoals, ItemGoals, and KillGoals left within the level (also see Creating Actors And Objects).
bool GrabOption (out string Options, out string Result) 
Grabs the next left option from a string. Result contains the part between the first "?" and the next "?" (if exist). Result is removed then from Options. If Options starts with "?", true is returned, otherwise false.
GetKeyValue (string Pair, out string Key, out string Value) 
Break up a key=value pair into its key and value.
bool HasOption (string Options, string InKey) 
See if an option was specified in the options string.
string ParseOption (string Options, string InKey) 
Find the most left option of kind "InKey=Value" in Options and returns Value if InKey has been found, an empty string else. Options stays unchanged.
ProcessServerTravel (string URL, bool bItems) 
Called when a map changes. Is responsible for handling the transfer of players and their inventory as well as ensuring that all logging for the level just played is tidied up.
bool AtCapacity (string Options) 
This function returns true if the server has the maximum number of players allowed on it.
bool CheckIPPolicy (string Address) 
Returns true if the IP address of the client is allowed to connect to the server.
int GetIntOption( string Options, string ParseString, int CurrentValue ) 
Same as ParseOption but returns an Integer. If the key ParseString is not found, CurrentValue is returned.
Logout (Pawn (UT) Exiting) 
Logs the player out and tells the logging engine about it.
AddDefaultInventory (Pawn (UT) PlayerPawn) 
Add any default inventory to the player.
NavigationPoint FindPlayerStart (Pawn (UT) Player, optional byte InTeam, optional string incomingName) 
Locates the "best" player start for the player.
bool RestartPlayer (Pawn (UT) aPlayer) 
Restart a player after he has died. This function adds the default inventory by calling AddDefaultInventory(), finds a start location by calling FindPlayerStart(). Once this has been acomplished, sets the player's stats back to defaults.
StartPlayer (PlayerPawn Other) 
Start a player. Finish me
Killed (Pawn (UT) Killer, Pawn (UT) Other, name damageType) 
Called when someone gets killed. This function broadcasts the death message, logs the event, and calls the ScoreKill() function.
BroadcastRegularDeathMessage (Pawn (UT) Killer, Pawn (UT) Other, name damageType) 
Calls on to BroadcastLocalizedMessage().
ScoreKill (Pawn (UT) Killer, Pawn (UT) Other)

Adds a message mutator at the front of the list of message mutators.
int ReduceDamage (int Damage, name DamageType, Pawn (UT) injured, Pawn (UT) instigatedBy) 
This function returns a damage of 0 if the injured Pawn (UT) is in a zone that has it's bNeutralZone property set to true. Otherwise the original damage is returned.
bool ShouldRespawn (Actor Other) 
Returns whether an actor item should respawn. In death matches this function should return true for weapon and item pickups.
bool PickupQuery (Pawn (UT) Other, Inventory (UT) Item) 
Called when pawn has a chance to pick Item up (i.e. when the pawn touches a weapon or item pickup). Should return true if it is allowed to pick it up, false if not.
DiscardInventory (Pawn (UT) Other) 
Discard a player's inventory after he dies.
float PlayerJumpZScaling ( ) 
Returns 1.0, but could be overidden for "low grav" game types.

bool SetEndCams (string Reason) 
Puts all player pawns into a GameEnded state and calls the ClientGameEnded() function on them. The function returns true.
ResetGame ( ) [static] 
GameInfo's ResetGame( ) does nothing. In Game type Assault it is overridden and some default values are reset and saved there.
bool AddBot ( ) 
GameInfo's AddBot( ) does nothing. It is overwitten in derivied game types, for example in DeathMatchPlus.
bool ForceAddBot ( ) 
GameInfo's ForceAddBot( ) does nothing. It is overridden in DeathMatchPlus.

PlayerPawn Login (string Portal, string Options, out string Error, class<PlayerPawn> SpawnClass)

Known subclasses


We could do with a nice time diagram showing when all of the different functions and events (including those on the mutators) get called.

Fearless: Hmmm, some interesting information here even if it's basic. I'd really like to do a mutator that changes gamespeed without the intervention of an admin. I have also a little question concerning the adminlogout command. It says here that the player is killed when the command is invoked. This does happen on our Linux 4.40 server but this doesn't happen on a server you're hosting yourself. Does anyone have any idea why this is :P ?

NogginBasher: You can do that using a combination of x3dfxMapVote and IdeFiX's ServerMode. In ServerMode.ini you need something like: "Commands[11]=SET Engine.GameInfo GameSpeed 1.25". I'm currently testing: "Commands[12]=SET Botpack.DeathMatchPlus bHardcoreMode True"
