Unreal Tournament Console Commands

 

Last updated by Michiel Hendriks, more toys for v3323. Previously updated by Chris Linder to include additional information. Original author was Martin Actor (UdnStaff?).

Overview

To use console commands, bring up the console and type them in. Console commands may be executed from within the game, from within the editor, or if the game has been started using the -server switch, from the server’s console. They can do various things from resetting the engine to setting particular actor’s variables.

Lists of commands can also be stored in text files in the system directory and executed by typing “exec filename ” at the console.

Command List

The following is a list of engine supported console commands

General Purpose

  • CANCEL – tells the engine to cancel an in progress connection attempt
  • DISCONNECT – disconnects the client from the current game/server
  • EXIT – tells the engine to shutdown and close the application
  • MAP – alias for START
  • OPEN – tells the engine to open a map by the name of the string that comes immediately after
  • QUIT – same as EXIT
  • RECONNECT – reconnects the client to the current game/server
  • SERVERTRAVEL – travels the client to the server by the name/address of the string that comes immediately after
  • START – similar to OPEN, difference is it does a TRAVEL_Absolute instead of TRAVEL_Partial

STAT ZONE

Debugging

DEBUG CRASH Test crashing the game by appError.
DEBUG EATMEM Test allocating memory until it fills up.
DEBUG GPF Test a general protection fault.
DEBUG RECURSE Test crash by infinite recursion.
DUMPCACHE Display the contents of the memory cache GCache.
DUMPNATIVES Display a list of unused native function ids.
EDITACTOR CLASS=classname During game play, edits the properties of the nearest actor belonging to that class. Cool for debugging.
GET <classname> <variable> Gets the default value for a variable in a class
MARK Mark all objects that are in memory (for garbage collection debugging in conjunction with MARKCHECK).
MARKCHECK Display a list of all unmarked objects that are in memory (for garbage collection debugging in conjunction with MARK).
MEM List memory usage; only works when Unreal is compiled with the memory-tracking option (it’s usually not).
MEMSTAT Show Windows overall memory statistics.
OBJ CLASSES Prints a list of all loaded classes.
OBJ DEPENDENCIES PACKAGE=pkgname EXCLUDE1=otherpackage EXCLUDE2=otherpackage… Show package dependencies
OBJ GARBAGE Collect and purge garbage (“garbage” means objects which are no longer in use).
OBJ HASH Show object hashing statistics.
OBJ LINKERS Show a list of active linkers (each linker is responsible for loading objects from a package file).
OBJ LIST CLASS=objectclass INSIDE=insideclass List all objects belonging to the class and residing inside the specified object. If the class isn’t specified, lists ALL objects. If the inside object isn’t specified, shows all objects. Gives a summary of memory usage. This is very useful during game play for figuring out how much memory is being used. In UnrealEd, this statistic isn’t useful because a huge amount of extra stuff is loaded which might not be used by your map.
OBJ REFS CLASS=objectclass NAME=objectname Show a list of objects which reference the object you specify. When trimming memory usage, this is useful for figuring out why some object is being loaded.
REPORT Copies a report of the current gameplay situation to the clipboard. You can then paste the resulting text into an email program, Notepad, etc. Extremely useful for beta testers, because it dumps the player’s X,Y,Z location, the difficulty level, etc.
RMODE Set the rendering mode. 0-9.
SET <class> <variable> <value> Sets the specified property of the specified class with the specified value
SHOWACTORS Shows actors during gameplay.
SOCKETS In network play, shows a list of network sockets (UNetConnection’s) in use.
URL urlname In network play, parses a URL and displays its components.

Unreal Tournament Key Bindings

In the Unreal Tournament key bindings (type PREFERENCES to bring up Advanced Options / Advanced / Raw Key Bindings), you can associate console commands and other special input commands with key presses and releases. In the text box next to a key name, you can type in one or more console commands, separated by the “|” character. For example, to bind the “S” key to the “Jump” alias, type this:

Jump

That causes the “Jump” alias to be executed when th user presses the “S” key. For another example, if you want to bind a chat message to a key, use this:

Say “Come get some!”

In addition, you can bind multiple actions to a keypress like this, to make the “S” key both jump and say a message.

Jump | Say “Come get some!”

You can also bind an action to the release of a key by using the OnRelease keyword. For example, you can make the “S” key fire when it’s released:

OnRelease Fire

Or you can make the key jump when pressed, and fire when released:

Jump | OnRelease Fire

Keys can be bound to any of the following kinds of things:

  • Any console command in the above lists.

  • Any key alias (explained below).

  • Any special input command.

“Special input command” refers to console commands which only make sense in conjunction with the press or release of a key, or the movement of the mouse or joystick along an axis. The special input commands are:

  • BUTTON <UnrealScript boolean variable name>, for example “BUTTON bFire”: Maps a button to an UnrealScript variable stored in the Pawn class or any subclass. This tells the input system to automatically set the variable to True when the key is held down, and False when it’s not pressed. For example, the Pawn script looks at bFire to tell whether the fire button is being held. The setting of bFire is not some hardcoded behavior of the engine, rather it is propagated into UnrealScript code by the input system, as a result of binding a key to “BUTTON bFire”.

  • TOGGLE <UnrealScript boolean variable name>, for example “TOGGLE bLook”: Like the BUTTON command, but simply tells the input system to toggle the boolean variable’s value when the key is pressed.

  • AXIS <UnrealScript floating point variable name> <SPEED=some number>, for example “Axis aStrafe Speed=-300.0”. Maps an analog input axis movement to an UnrealScript variable, scaling it by some factor. The current axis keys listed in the Advanced Options menu are: MouseX, MouseY, MouseW (Intellimouse wheel), JoyX, JoyY, JoyZ, JoyR (joystick rudder), JoyU, JoyV (joystick alternate axis for example the Panther XL trackball). Supported PlayerPawn axes are aBaseX, aBaseY (base movements which are translated to rotating, strafing, looking, and forward movement based on context), aMouseX, aMouseY, aForward, aTurn, aStrafe, aUp (not used), aLookUp, aExtra0-aExtra4 (not used). To see how the game code processes movement, see the PlayerPawn class’s PlayerInput and PlayerTick functions.

In addition to the Advance Options menu, you can also bind keys from the console using the following command:

SET INPUT <keyname> <binding>

For example:

SET INPUT X Fire
SET INPUT Enter Fire

Unreal Tournament Key Aliases

Key aliases are listed in Advanced Options / Advanced / Input Aliases. Aliases provide a convenient way to map one word (for example, “Jump”) to a complex series of console commands that carry out a particular action. For example, the “Fire” alias is defined as: “Fire | Button bFire”. This has the effect of calling the UnrealScript “PlayerPawn.Fire” function (aliases are not recursive), and then causing the input button bJump to be set to True as long as the key is held.

C++ Console Commands

These only work on the local machine.

BRIGHTNESS Cycle through 10 screen brightness values.
CANCEL Cancels an “open” command in progress that is trying to connect to a network server.
CDTRACK num Play the specified CD track.
CPUSPEED=# Identify your CPU speed, useful for machines which don’t autodetect their speed properly. For example, CPUSPEED=266.
DEMOPLAY <filename>
[?noframecap]
[?timebased]
[?3rdperson]
Play a recorded demo. noframecap plays the demo back as fast as possible. This option is assumed if timedemo 1 is enabled. timebased gives a smoother playback if the playback machine is significantly slower than the recording machine. 3rdperson lets you fly around a first person demo as a spectator. eg demoplay mydemo?3rdperson?timebased
DEMOREC <filename> Record a demo to <filename>
DISCONNECT Disconnect from the current server
ENDFULLSCREEN Go back to playing in a window.
EXEC filename Execute the console commands in the filename, default is in the System directory.
EXIT Exit the game..

Debugging

DEBUG CRASH Test crashing the game by appError.
DEBUG EATMEM Test allocating memory until it fills up.
DEBUG GPF Test a general protection fault.
DEBUG RECURSE Test crash by infinite recursion.
DUMPCACHE Display the contents of the memory cache GCache.
DUMPNATIVES Display a list of unused native function ids.
EDITACTOR CLASS=classname During game play, edits the properties of the nearest actor belonging to that class. Cool for debugging.
GET <classname> <variable> Gets the default value for a variable in a class
MARK Mark all objects that are in memory (for garbage collection debugging in conjunction with MARKCHECK).
MARKCHECK Display a list of all unmarked objects that are in memory (for garbage collection debugging in conjunction with MARK).
MEM List memory usage; only works when Unreal is compiled with the memory-tracking option (it’s usually not).
MEMSTAT Show Windows overall memory statistics.
OBJ CLASSES Prints a list of all loaded classes.
OBJ DEPENDENCIES PACKAGE=pkgname EXCLUDE1=otherpackage EXCLUDE2=otherpackage… Show package dependencies
OBJ GARBAGE Collect and purge garbage (“garbage” means objects which are no longer in use).
OBJ HASH Show object hashing statistics.
OBJ LINKERS Show a list of active linkers (each linker is responsible for loading objects from a package file).
OBJ LIST CLASS=objectclass INSIDE=insideclass List all objects belonging to the class and residing inside the specified object. If the class isn’t specified, lists ALL objects. If the inside object isn’t specified, shows all objects. Gives a summary of memory usage. This is very useful during game play for figuring out how much memory is being used. In UnrealEd, this statistic isn’t useful because a huge amount of extra stuff is loaded which might not be used by your map.
OBJ REFS CLASS=objectclass NAME=objectname Show a list of objects which reference the object you specify. When trimming memory usage, this is useful for figuring out why some object is being loaded.
REPORT Copies a report of the current gameplay situation to the clipboard. You can then paste the resulting text into an email program, Notepad, etc. Extremely useful for beta testers, because it dumps the player’s X,Y,Z location, the difficulty level, etc.
RMODE Set the rendering mode. 0-9.
SET <class> <variable> <value> Sets the specified property of the specified class with the specified value
SHOWACTORS Shows actors during gameplay.
SOCKETS In network play, shows a list of network sockets (UNetConnection’s) in use.
URL urlname In network play, parses a URL and displays its components.

Unreal Tournament Key Bindings

In the Unreal Tournament key bindings (type PREFERENCES to bring up Advanced Options / Advanced / Raw Key Bindings), you can associate console commands and other special input commands with key presses and releases. In the text box next to a key name, you can type in one or more console commands, separated by the “|” character. For example, to bind the “S” key to the “Jump” alias, type this:

Jump

That causes the “Jump” alias to be executed when th user presses the “S” key. For another example, if you want to bind a chat message to a key, use this:

Say “Come get some!”

In addition, you can bind multiple actions to a keypress like this, to make the “S” key both jump and say a message.

Jump | Say “Come get some!”

You can also bind an action to the release of a key by using the OnRelease keyword. For example, you can make the “S” key fire when it’s released:

OnRelease Fire

Or you can make the key jump when pressed, and fire when released:

Jump | OnRelease Fire

Keys can be bound to any of the following kinds of things:

  • Any console command in the above lists.

  • Any key alias (explained below).

  • Any special input command.

“Special input command” refers to console commands which only make sense in conjunction with the press or release of a key, or the movement of the mouse or joystick along an axis. The special input commands are:

  • BUTTON <UnrealScript boolean variable name>, for example “BUTTON bFire”: Maps a button to an UnrealScript variable stored in the Pawn class or any subclass. This tells the input system to automatically set the variable to True when the key is held down, and False when it’s not pressed. For example, the Pawn script looks at bFire to tell whether the fire button is being held. The setting of bFire is not some hardcoded behavior of the engine, rather it is propagated into UnrealScript code by the input system, as a result of binding a key to “BUTTON bFire”.

  • TOGGLE <UnrealScript boolean variable name>, for example “TOGGLE bLook”: Like the BUTTON command, but simply tells the input system to toggle the boolean variable’s value when the key is pressed.

  • AXIS <UnrealScript floating point variable name> <SPEED=some number>, for example “Axis aStrafe Speed=-300.0”. Maps an analog input axis movement to an UnrealScript variable, scaling it by some factor. The current axis keys listed in the Advanced Options menu are: MouseX, MouseY, MouseW (Intellimouse wheel), JoyX, JoyY, JoyZ, JoyR (joystick rudder), JoyU, JoyV (joystick alternate axis for example the Panther XL trackball). Supported PlayerPawn axes are aBaseX, aBaseY (base movements which are translated to rotating, strafing, looking, and forward movement based on context), aMouseX, aMouseY, aForward, aTurn, aStrafe, aUp (not used), aLookUp, aExtra0-aExtra4 (not used). To see how the game code processes movement, see the PlayerPawn class’s PlayerInput and PlayerTick functions.

In addition to the Advance Options menu, you can also bind keys from the console using the following command:

SET INPUT <keyname> <binding>

For example:

SET INPUT X Fire
SET INPUT Enter Fire

Unreal Tournament Key Aliases

Key aliases are listed in Advanced Options / Advanced / Input Aliases. Aliases provide a convenient way to map one word (for example, “Jump”) to a complex series of console commands that carry out a particular action. For example, the “Fire” alias is defined as: “Fire | Button bFire”. This has the effect of calling the UnrealScript “PlayerPawn.Fire” function (aliases are not recursive), and then causing the input button bJump to be set to True as long as the key is held.
