SWITCHCOOPLEVEL : Causes the server (or local machine, in a single-player game) to switch to a new level with coop-style weapon carrying between levels.
SWITCHLEVEL : Causes the server (or local machine, in a single-player game) to switch to a new level.
Command Line Parameters
-profile: When C++ is compiled with DO_SLOW_GUARD=1, generates an UnrealScript function profile using the timings in the most recently played level only.
-nosound: Disables sound.
-nodsound: Disables DirectSound support.
-noddraw: Disables DirectDraw support.
-nohard: Disables 3d hardware support.
-log: Runs with the log window initially visible.
-firstrun: Re-asks the "First Run" questions in Unreal.
-nologwin: Don't output to log window, useful for debugging when printing so many log messages that performance is slowed down by window updates.
-conflicts: Show objects of different classes whose names conflict.
-nok6: Disable AMD K6-3D support.
-nommx: Disables MMX support.
-noreplace: Don't automatically replace textures, sounds, and music if they are not found.
-make: Rebuilds all .u files from their source .uc files.
-make -h: Rebuilds all .u files from their source .uc files and generate a C++ header for each package.
-editor: Runs Unreal for editing.
-server: Runs as a dedicated server.
-strict: Treat all script warnings as critical errors; useful for tracking down the call stack when debugging scripts.
-nobind: Don't treat UnrealScript/C++ binding errors as critical, for rebuilding scripts and avoiding the chicken-and-egg binding problem.
-showdep: Causes script compiler to log dependency information when recompiling scripts.
-nogc: Disables garbage collection.
-alladmin: Enable all players administrative access to the server. LOG=logfilename: Uses the specified log file instead of Unreal.log. Useful when running multiple copies on the same machine.
INI=inifilename: Sets the .ini file to use for configuration, normally Unreal.ini.
READINI=inifilename: Sets the .ini file for reading only (not for writing); overrides the INI= option. PORT=num: Sets the UDP port number for the Internet server.
MULTIHOME=126.96.36.199: Sets the "home" ip address (in numerical format) for Unreal of a machine with multiple network cards.
C++ Console Commands
(Only works on the local machine)
BRIGHTNESS: Cycle through 10 screen brightness values.
CHAT: Brings up a prompt to type chat text.
CANCEL: Cancels an "open" command in progress that is trying to connect to a network server.
CDTRACK num: Play the specified CD track.
CONSOLE FULL: Make the console fullscreen.
CONSOLE HIDE: Hide the console.
CONSOLE SHOW: Show the console.
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.
DUMPINTRINSICS: Display a list of unused intrinsic function ids.
EDITACTOR CLASS=classname: During game play, edits the properties of the nearest actor belonging to that class. Cool for debugging.
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 program.
FLUSH: Flush all caches. Regenerates all lighting, 3d hardware textures, etc.
HIDEACTORS: Hide actors during game play.
JUMPTO x y z: In UnrealEd, move the viewport to a certain X,Y,Z location, useful in conjunction with tester reports generated with the REPORT command.
LOADGAME num: Load a game in position 0-9.
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.
MUSICORDER num: Change to a certain track in the song (0=ambient, 1=action, 2=suspense).
OBJ CLASSES: Prints a list of all loaded classes.
OBJ DEPENDENCIES PACKAGE=pkgname EXCLUDE1=otherpackage EXCLUDE2=otherpackage...: !!
OBJ GARBAGE: Collect and purge garbage ("garbage" means objects which are no longer in use).
OBJ HASH: Show object hashing statistics.
OBJ LIST CLASS=objectclass: List all objects belonging to the class (if the class isn't specified, lists 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.
OPEN url: Opens a local map (i.e. "unreal.unr") or an Internet server (i.e. "188.8.131.52" or "unreal.epicgames.com").
PREFERENCES: Displays the preferences in a window.
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.
SAVEGAME num: Save the game in a specified position, 0-9.
SHOT: Take a screenshot and save it in the System directory with a consecutive name like Shot0001.bmp.
SHOWACTORS: Shows actors during gameplay.
SOCKETS: In network play, shows a list of network sockets (UNetConnection's) in use.
STAT ACTOR: Shows various statistics.
STAT FPS - the number is in milliseconds. 1000 divided by this number is your FPS
TOGGLEFULLSCREEN: Toggles fullscreen mode on and off.
TYPE: Types text on the console.
URL urlname: In network play, parses a URL and displays its components.
VIEWUP: Sizes the view up. VIEWDOWN: Sizes the view down.
