Console commands carry out a particular action when sent to the console.

Console commands[edit]

Console commands are executed, they don't inherently store values to be checked.

Flags[edit]

Console commands have flags assigned to them, which alter their usability. They are:

  • buffered: wait until all screen has rendered before running command.
  • hidden: not showing when running cmdlist.
  • level: only runnable during levels.
  • netvar: under multiplayer, synchronizes with the other players.
  • notnet: forbidden in multiplayer (unless during a demo).
  • server: if under multiplayer, only triggerable by the "server" player.

Categories[edit]

The commands can be grouped by their purpose:

  • Control: general game control.
  • Core: main console stuff, such as "echo" or "delay".
  • I/O: input/output setup.
  • Information: purely informative commands. Can be executed any time as they don't affect the game.
  • Logging: special console logging commands.
  • Menu: commands that show various menus, as well as a few commands with actual effects, which depend on the current menu state, and can't be run standalone.
  • Testing: gameplay testing and "cheating" commands.

List of console commands[edit]

Name Parameters Flags Category Description
addfile wadfilename buffered notnet Control Adds the specified wad file at run-time. Some features will not function completely as expected when WADs are loaded at run-time, so for maximum compatibility always use the command line to load files.
alias newcmdname command Core alias alone will list all currently defined aliases. Providing newcmdname alone will remove that alias if it exists. Providing newcmdname and a valid console command will create "newcmdname" as an alias to that command, allowing shortcuts.

In order to make an alias take parameters, use the special variable "%opt", as such:

 alias "mycommand" "hu_overlay %opt"
animshot numframes Control Takes the given number of consecutive screenshots for the purpose of making a crude animation. Would be useful for animated GIFs or AVI movies. This command will make the game run very slow, however, and will eat up disk space quickly, so use it with care.
banish level notnet Testing If the player is autoaiming at an enemy, the enemy will be removed from the play simulation and its memory will be freed once no other objects reference it.
bind keyname actionname I/O Binds the specified action to the specified key. actionname is a string and should be enclosed in quotes if it contains whitespace. actionname may specify any valid action or console command. If "actionname" is not provided, the current binding status of the specified key will be displayed.
bindings Information Dumps a list of all active keybindings to the console.
buddha level notnet Testing Toggles "Buddha" mode, where you can take any amount of damage without dying.
c_popup Core Instantly removes the console from view.
closelog Logging Closes a console log opened by the openlog command. If no logging is currently occuring, this command does nothing. This command doesn't apply to files used by dumplog, as they are closed immediately, so it doesn't need to be used with the dumplog command.
cmdlist filter Core Displays all user-visible console commands, one per line. As of Eternity Engine v3.31 Delta, this command accepts an optional filter parameter that, if provided, should consist of a single character between A and Z. The character will be used to filter the command list down to only commands beginning with that letter.
creator Information Displays the name of the creator as set in EMAPINFO.
credits Menu Displays game engine / game credits.
cvarhelp variablename Core Outputs a list of possible values for the given variable.
delay amt Core Delays the running of the next console command by either 1, or if provided, by amt game tics.
defdmflags mode server Control Sets the deathmatch flags variable to its default settings. If no argument is provided, dmflags is set to the default for the current game type. Otherwise, the "mode" parameter indicates what game mode's defaults to set, with the following values:
  • 0 = Single-player mode
  • 1 = Cooperative mode
  • 2 = Deathmatch mode
  • 3 = Altdeath mode (deathmatch 2.0, items respawn)
  • 4 = Trideath mode (DM 3, barrels respawn, players drop backpacks)
dir Information Lists the contents of the current working directory to the console.
dumplog filename Logging Dumps the current state of the console message buffer to the specified file as ASCII text. The text will be appended to the file if it already exists, allowing multiple use of a single log file.

e_listkeyitems Information Lists all key-type artifact definitions.
e_listlinedefs level Information Lists all linedef definitions from the current map's ExtraData. If no linedefs are defined or no ExtraData exists for the current map, an appropriate error message will be given.
e_listmapthings level Information Lists all mapthing definitions from the current map's ExtraData. If no mapthings are defined or no ExtraData exists for the current map, an appropriate error message will be given.
e_mapthing recordnum level Information Lists verbose information on an ExtraData mapthing record with the given numeric record number. If no such mapthing is defined or no ExtraData exists for the current map, an appropriate error message will be given.
e_playsound name Testing Plays an EDF sound.
