Commands which take parameters may accept numbers, strings, or members of a predefined set of values.

  ex:
  $ delay 50
  $ spawn 249 1
  $ name Quasar
  $ hu_overlay distributed

  ex:
  $ echo "This has to be in quotes"
  $ i_error "R_FindVisplane: no more visplanes!"

  ex:
  $ delay; kill

• +
  Affixed to the end of the variable, it will increment it to the next valid value, but no higher than the maximum allowed.

      ex:
      $ screensize +
      

• -
  Affixed to the end of the variable, it will decrement it to the next lower valid value, but no lower than the minimum allowed.

      ex:
      $ screensize -
      

• /
  Toggles through the variable values from minimum to maximum, wrapping around to the minimum value again when it is maxed out. This is most useful with two-state yes/no and on/off variables.

      ex:
      $ hu_overlay /
      

In the list below, command arguments enclosed in brackets are optional. Commands typically have some default behavior when the arguments they expect are not provided, although this is often to simply print usage information.

An ellipsis (...) signifies that the command will accept any number of arguments and will amalgamate them into one continuous string.

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

These commands are for manipulating the console itself.

Synopsis of Commands:

	* flood		* echo
	* delay		* dumplog
	* alias 	* openlog
	* cmdlist	* closelog
	* quote         * dir

• flood
  
  Writes 300 garbage characters to the console. Usefulness is of debate.
  
  
• delay <amt>
  
  Delays the running of the next console command by either 1, or if provided, by amt game tics.
  
  
• alias <newcmdname> <command>
  
  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"
    

• cmdlist <filter>
  
  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.
  
  
• quote
  
  Just for fun, displays a random quote from IRC.
  
  
• echo msg
  
  Echoes a string message to the console. As with all console strings, the string should be in quotes if it contains whitespace.
  
  
• dumplog filename
  
  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.
  
  
• openlog filename
  
  Opens the specified file in append mode and begins writing any text printed to the console into the file. All console messages will be logged until either the closelog command is used, or the program closes. Note this log file is totally separate from any used with the "dumplog" command, which is simply for saving the current buffer. If a log file is already open, this command does nothing.
  
  
• closelog
  
  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.
  
  
• dir
  
  Lists the contents of the current working directory to the console.

These commands display and affect various aspects of the menu system.

• p_linespec name <arg> <arg> <arg> <arg> <arg>
  
  Executes the named Eternity Engine parameterized line special (as documented in editref.html) with the given parameters. The line special is restricted to behaving as though it has been invoked without any linedef to reference, and thus certain effects such as sector special transfers will not occur even if specified by the special type or arguments.
  Flags: not in a network game, only in levels.

These commands are related to the Eternity Definition Files (EDF) system. They expose information which may be useful for editing or for use with other console commands.

Synopsis of Commands:

• e_mapthing recordnum
  
  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_listlinedefs
  
  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_linedef recordnum
  
  Lists verbose information on an ExtraData linedef record with the given numeric record number. If no such linedef is defined or no ExtraData exists for the current map, an appropriate error message will be given.

These commands are related to the Small scripting engine.

Synopsis of Commands:

	* a_running
	* a_execv
	* a_execi

• a_running
  
  Prints debug information about the currently running script callbacks. The data listed is as follows: internal script number, internal callback type number, and callback data (wait time or sector tag).
  
  
• a_execv vm scriptname
  
  Executes a public Small script, passing no parameters (use this for scripts declared with an empty parameter list). The "vm" parameter should be 0 to indicate the Gamescript VM, or 1 to indicate the Levelscript VM. If the indicated VM isn't valid, an error message will be displayed. The indicated script will run under the INVOKE_CCMD invocation model.
  
  
• a_execi vm scriptname ... Executes a public Small script, passing one or more integer parameters provided to this command. You cannot pass string values to Small functions using this command. The number of parameters passed should match the prototype of the Small function being invoked, or an error may occur. The "vm" parameter should be 0 to indicate the Gamescript VM, or 1 to indicate the Levelscript VM. If the indicated VM isn't valid, an error message will be displayed. The indicated script will run under the INVOKE_CCMD invocation model.

Variables differ from commands in that they are assigned values rather than performing actions directly.

  * NOTE: on and off for this variable do not equate to flipped or non-flipped in the same way for every combination of sound card and/or Allego configuration. If your sound is right, turning on s_flippan will make it wrong. If your sound is wrong, try this to make it right.
  
  
• s_precache
  type: on / off
  on = sounds will be precached at the beginning of the game
  off = sounds will be loaded as they are used
  
  * NOTE: off will make load times shorter, but may degrade performance. on may require more system memory.

  off = sounds always play at real pitch
  
  
• snd_channels
  type: integer
  value range: 0 - 128
  value = number of software channels to maintain
  
  * NOTE: this has nothing to do with the number of available hardware channels, which, unless you are very rich, is probably nowhere near 128 :P
  
  This value affects the number of sounds the game will *attempt* to play at one time. If set too low, you will lose sound unnecessarily. Setting it too high will use more memory and take more time to process.
