gzdoom/docs/commands.txt

This document lists all commands and cvars supported by the current version
of ZDoom (1.22) and a short description of each. There are a total of 130
commands and 141 cvars.
===========================================================================

There are five types of cvars:

boolean:  This is a number that can be either "0" or "1". "0" indicates no/
          false, and "1" indicates yes/true.

  color:  This is a series of three hexadecimal numbers representing the
          amounts of red, green, and blue (in that order) in a color. For
          example, pure redwould be represented as "ffff 0000 0000". The
          setcolor command can be used to set one of these cvars using a
          color name instead of numbers. (See the description of the
          setcolor command below.)

 number:  This is an ordinary number.

 integer: This is an ordinary that doesn't take fractional values.

 string:  This is a series of text characters enclosed in quotes.


Some commands also take parameters. Any parameters that are required are 
enclosed in < >, and those that are optional are enclosed in [ ].


ACTION COMMANDS

OTHER COMMANDS AND CVARS
========================
addbot [name]
(command)
 Spawns a bot. If a name is given, the corresponding bot in bots.cfg will be
 spawned. Otherwise, a bot will be picked at random from bots.cfg.

alias <new command> <command string>
(command)
 If specified with no parameters, will display a list of all current
 aliases. If only <new command> is specified, it will be removed from the
 list of aliases. If <command string> is also specified, it will be added
 to the list of aliases as <new command>. For example, to create a new
 command to kill the monsters on the level, you can use the command:

     alias massacre kill monsters

 Then, you can use the newly created massacre command to kill all the
 monsters on the level.

alwaysapplydmflags

 Normally, some dmflags are only used in deathmatch. If alwaysapplydmflags
 is 1, then they will also be used in single-player and co-op games.

am_overlay
(cvar: boolean)
default: 0
 Normally, the togglemap command switches the automap between fully off and
 fully on. Setting this cvar to "1" will cause togglemap to draw the
 automap on top of the player's view before it draws the automap
 fullscreen. (Bad description, I know. Just try it)
See also: am_rotate, togglemap

am_ovotherwallscolor
(cvar: color)

 automap is activated.
See also: all the am_* cvars

am_rotate
(cvar: boolean)
default: 0
 Normally, the automap is always drawn such that north is at the top of the
 screen. Setting this cvar to "1" causes the automap to be drawn so that
 lines toward the top of the screen are always directly in front of the
 player's view. Changes to this cvar take effect immediately, unlike most
 of the other am_* cvars. This can be particularly useful when the automap
 is overlayed.

autoaim
(cvar: number)
default: 5000
 This represents the vertical distance from an object that the player's
 sight must be before that object is aimed at. Setting this cvar to "0"
 disables autoaiming, while large values such as "5000" will reproduce the
 original DOOM behavior of always autoaiming.
See also: color, name

autoexec
(cvar: string)
default: "<PROGDIR>/autoexec.cfg"
 This is a file that will be automatically executed by ZDoom each time it
 starts. This file is executed immediately after the config file is loaded.
 It should contain a series of console commands. C++ style comments are
 also supported. Comments begin with // and anything after them until the
 end of the line will be ignored.

 <PROGDIR> represents the directory that ZDoom is in and will naturally
 vary depending on where you put it.

bind [key [command string]]
(command)
 If no parameters are specified, the entire list of bound keys will be
 printed to the console. If only [key] is specified, the binding for that
 specific key will be printed. If both [key] and [command string] are
 specified, [command string] will be bound to [key].
See also: doublebind, unbind, unbindall, undoublebind

binddefaults
(command)
 Binds all keys to their default commands. This will not unbind any keys
 that do not have any default bindings, so if you want to properly restore
 the default controls, you need to use unbindall first.
See also: unbindall, bind

bot_allowspy
(cvar: boolean)
default: 0
 Allows you to see through the eyes of bots during botmatch games.

bot_next_color
(cvar: number)
default: 11
 Theoretically, a number representing the color of the next bot to be
 spawned. In practice, it doesn't do anything.

bot_observer
(cvar: boolean)
default: 0
 When set to 1, the player will experience minimal interaction with the
 world, and bots will ignore him.

bumpgamma
(command)
 Increases the current gamma level by 0.1. If the new gamma level would be
 greater than 3.0, it wraps the gamma around to 1.0
See also: gamma

centerview
(command)
 Causes the player to look straight ahead.
See also: +lookup, +lookdown

changemap <map>
(command)
 Exits the current level and continues the game on the specified map.
 Unlike the map and idclev commands, this command *will* work properly
 during network games and is recorded in demos. Unfortunately, it has
 occasionally resulted in some problems. It should, however, be safe
 enough to use most of the time.
See also: idclev, map

changemus <music>
(command)
 Changes the currently playing music. <music> should be the name of a music
 lump or file on disk (which need not have been specified with the -file
 parameter).
See also: dir, idmus

chase
(command)
 Turns the chasecom on and off. This command also works while watching
 demos, so you can bind it to a key and watch demos in the third person.
See also: chase_dist, chase_height, chasedemo

chase_dist
(cvar: number)
default: 90
 This is how far away from the player the chasecam likes to be, but it will
 get closer as necessary to avoid going inside walls.
See also: chase, chase_height

chase_height
(cvar: number)
default: -8
 This is the base height above the top of the player's head that the
 chasecam will be positioned at. Looking up and down will move the camera
 in the opposite direction so that the player stays at approximately the
 same height on the screen. Large values of this cvar (either positive or
 negative) will produce strange output.
See also: chase, chase_dist

chasedemo
(cvar: boolean)
default: 0
 If this cvar is true, then demos will automatically start with the
 chasecam active.
See also: chase

chatmacro0
chatmacro1
chatmacro2
chatmacro3
chatmacro4
chatmacro5
chatmacro6
chatmacro7
chatmacro8
chatmacro9
(cvar: string)
 These are all strings programmable to the function keys during a netgame.
 To use these, enter chat mode with the messagemode command, and then hold
 down Alt and press one of the number keys. The string stored in the
 corresponding chatmacro cvar will be sent as if you had typed it yourself.

cl_bloodtype
(cvar: number)
default: 0
 Controls how blood is drawn. Supported values are:
    0: Blood is drawn as sprites
    1: Blood is drawn as both sprites and particles

cl_rockettrails
(cvar: boolean)
default: 1
 Controls whether or not rockets leave trails of smoke behind them.

cl_run
(cvar: boolean)

con_midtime
(cvar: number)
default: 3
 This is the number of seconds that messages in the middle of the screen

See also: con_notifytime

con_notifytime
(cvar: number)
default: 3
 This is the number of seconds that new messages will stay at the top of
 the screen before they start scrolling away.
See also: con_midtime

con_scaletext
(cvar: boolean)
default: 0
 If this cvar is true, then message text will be scaled to larger sizes
 depending on the screen resolution so that it will stay approximately the
 same size it would be on a 320x200 screen.

configver
(cvar: number)
default: "116"
 This cvar is used to keep track of which version of ZDoom was used to write
 the current config file and adjust for differences that may have been
 introduced between versions. Changing it has no effect, since it will
 always be changed to reflect the current game version before the config
 file is saved.

crosshair
(cvar: number)
default: 0
 If this cvar is non-zero, it draws a crosshair. If this cvar is negative,
 the crosshair is translucent, otherwise it is opaque. The specific
 crosshair drawn depends on the value of this cvar.

cvarlist
(command)
 Lists the values of all currently defined cvars. Each cvar can also be
 prefaced by multiple flags. These are:

    A Cvar gets saved in the config file.
    U Cvar contains user info.
    S Cvar contains server info.
    - Cvar can only be changed from the command line.
    L Changes to cvar's contents don't take effect until the next game.
    C Cvar has an internal callback.
    * Cvar was created by the user and is meaningless to the game.

 This is the color to mix with the background when a menu is displayed.
See also: dimamount, setcolor

dir [[path/][pattern]]
(command)

 will not recurse into multiple directories). If [path] is not specified,
 it will display the contents of the directory the game was run from.

deathmatch
(cvar: boolean)

 When set to true, the game is treated as a deathmatch. When the game is
 started with -altdeath or -deathmatch, this cvar is automatically set to 1.

dmflags
(cvar: number)
default: 0
 This cvar controls the behavior of several aspects of gameplay. To
 determine what value to store in this cvar, select the desired features
 from the table below and add their values together. If a feature is
 marked with (DM), then that feature will only be active during a
 deathmatch game.

doublebind [key [command string]]
(command)
 If no parameters are specified, the entire list of doublebound keys will be
 printed to the console. If only [key] is specified, the doublebinding for
 that specific key will be printed. If both [key] and [command string] are
 specified, [command string] will be doublebound to [key]. (Doublebindings
 are commands that are executed when a key is pressed twice quickly--such as
 double cliking a mouse button.)
See also: bind, unbind, unbindall, undoublebind

dumpheap
(command)
 Prints detailed information about the heap. Probably not very useful to
 the average user.
See also: mem

echo <string>
(command)
 Prints <string> to the console.

endgame
(command)
 Ends the current single player game and drops the console down to cover the
 screen.
See also: menu_endgame

error <error message>
(command)
 Simulates an error by killing the current game and falling back to the
 fullscreen console with the specified message.

exec <script file>
(command)
 Executes a series of commands stored in the <script file> as if they were
 typed in at the console.

fly
(command)
 Toggles fly mode on and off.

forcewater
(cvar: boolean)
default: 0
 When set to 1, all BOOM-style deep water will be swimmable. This is not
 the default, because the effect can be used for more than just deep water
 (although water is probably its most common use).

fov [viewfield]
(command)
 When used without a parameter, returns the current field of vision. When
 viewfield is specified, sets the field of vision. This can be between 1
 and 179 degrees. The default is 90.

fraglimit
(cvar: number)
default: 0
 If this cvar is non-zero, the game will automatically advance to the next
 level once anyone gets this many frags. (deathmatch only)
See also: timelimit

freelook

default: 0
 When true, mouse aiming will always be on, regardless of the state of
 +mlook.
See also: +mlook, invertmouse

freeze
(command)
 Use this command once to freeze gameplay (while still allowing you to move
 around). Use it again to unfreeze gameplay.

fullscreen
(cvar: boolean)
default: 1
 If this cvar is true, the game will be displayed fullscreen. Otherwise, it
 will be drawn in a window.

gameversion
(command)
 Prints the version number and compile date of ZDoom.

gamma
(cvar: number)
default: 1.0
 If <level> is not specified, displays the current gamma correction level. 
 Otherwise, sets the gamma correction level to <level>. 1.0 is equivalent
 to no correction, while larger numbers translate into a brighter display,
 and smaller numbers translate into a darker display. 0.0 is invalid and
 will be rejected. Negative numbers are technically invalid as well but
 will be accepted solely for the novelty value doing so provides.
See also: bumpgamma

gender
(cvar: string)
default: "male"
 This is the gender of your player. Valid values are "male", "female", and
 "neuter". Anything else will be treated as male. When you die, certain
 messages will be altered to reflect the gender selected here.
 Unfortunately, I don't provide any non-male player sounds, so you'll still
 sound like a man no matter what this cvar is set to unless you provide your
 own sounds.
See also: color, name, skin, team

get <cvar>
 Displays the value of <cvar>. This is probably redundant since typing the
 name of the cvar alone will accomplish the same thing.
See also: cvarlist, set

give <item>
(command)
 Gives an item to the player. This is a cheat. Give understands the
 following items:

    all - gives you everything
    health - gives you full health
    weapons - gives you every weapon

god
(command)
 Toggles God (Degreelessness) mode on/off. While active, you cannot be hurt
 by normal attacks (although telefragging will still kill you). Also known
 as iddqd. This is (of course) a cheat.
See also: sv_cheats

history
(command)
 Prints the console command history.

hud_scale
(cvar: boolean)
default: 0
 Controls scaling of the fullscreen hud. At resolutions of 640x400 or above,
 setting this cvar to 1 will cause the icons to be scaled to approximately
 the same size they would be at 320x200. If this cvar is 0, the icons will
 always be drawn without any scaling.

idclev <level code>
(command)
 Changes to the level specified by <level code>.

iddqd
 See god.

idmus <level code>
(command)
 Changes the music to that associated with the specified level.
See also: changemus

idmypos
(cvar: boolean)
default: 0
 When non-zero, constantly displays the player's current position and view
 angle.
See also: idmypos (command)

impulse <number>
(command)
 This is currently a hack to get weapon selection to work with keybindings
 until I finalize the inventory system (at which time, I plan to handle
 weapon selections as they are in Quake2). <number> can be a value ranging
 between 1 and 7 inclusive and will select the corresponding weapon. Values
 between 50 and 57 inclusive can be used to specify specific weapons instead
 of rolling between the fist/chainsaw and shotgun/ssg with impulses 1 and 3.
See also: weapnext, weapprev

i_remapkeypad
(cvar: boolean)
default: 1
 When non-zero, most keypad keys will act like the keys in the cursor
 island between the main keyboard and the numeric keypad. For instance,
 when this cvar is true, pressing "4" on the keypad is the same as pressing
 the left arrow on the cursor island. If you need to map different commands
 specifically to keys on the numeric keypad, set i_remapkeypad to "0".

in_mouse
(cvar: number)
default: 0
 This cvar select which method ZDoom will use to read the mouse. Valid
 values are:
    0: Automatically select a method based on the operating system.
    1: Use normal Win32 API calls (default for Windows NT).
    2: Use DirectInput (default for Windows 95/98).

invertmouse
(cvar: boolean)
default: 0
 When true, reverses the way mouse movement up and down is interpreted with
 +mlook. Normally, moving the mouse forward will make you look up, and
 moving it back will make you look down. Setting this cvar to true changes
 this behavior so that moving the mouse forward makes you look down, and
 moving it back makes you lookup.
See also: +mlook, freelook

joy_speedmultipiler
(cvar: number)
default: 1.0
 This cvar controls the overall sensitivity/movement speed possible with a
 joystick. Values above 1.0 will allow you to reach full speed with less
 movement of the joystick, but they will not let you go any faster than
 normal (use the turbo cvar for that). Values less than 1.0 will prevent
 you from reaching full speed with the joystick. One potentially useful
 trick is to create these two aliases:
    alias +creep "joy_speedmultiplier 0.25"
    alias -creep "joy_speedmultiplier 1.0"
 If you bind +creep to a button, then whenever that button is held down, you
 will walk with the joystick instead of run.
See also: joy_xsensitivity, joy_ysensitivity

joy_xsensitivity
(cvar: number)
default: 1.0
 This cvar controls how far the joystick needs to be moved horizontally to
 reach full speed for turning or strafing.
See also: joy_speedmultipiler, joy_ysensitivity

joy_xthreshold
(cvar: number)
default: 0.15
 This cvar is used to set the size of the joystick's horizontal "dead zone."
 Larger numbers correspond to a larger dead zone. The joystick needs to be
 outside this zone before its movement will register with the game.
See also: joy_xsensitivity, joy_ythreshold

joy_ysensitivity
(cvar: number)
default: -1.0
 This cvar controls how far the joystick needs to be moved vertically to
 reach full speed for moving forward and backward or looking up and down.
See also: joy_speedmultipiler, joy_xsenstivity

joy_ythreshold
(cvar: number)
default: 0.15
 This cvar is used to set the size of the joystick's vertical "dead zone."
 Larger numbers correspond to a larger dead zone. The joystick needs to be
 outside this zone before its movement will register with the game.
See also: joy_xthreshold, joy_ysensitivity

 Otherwise, it will kill you instead. This command is broken in netgames,
 so don't use it unless you are playing a single player game.

limits
(command)
 Prints the current state of all dynamic limits in ZDoom. These are only
 limits in the sense that they were limits in the original Doom. In ZDoom,

See also: msg0color, msg1color, msg2color, msg3color, msg4color

name
(cvar: string)
default: "Player"

 multiplayer game, but it can also be set for single player.
See also: color, gender, skin, team

neverswitchonpickup
(cvar: boolean)
default: 0
 When this cvar is true, you won't automatically switch to a new weapon
 when you pick one up.

nobfgaim
(cvar: boolean)
default: 0

 down if you shoot it at something, but you won't be able to, for instance,
 shoot it at the ground to quickly generate tracer damage by looking down.

noclip
(command)
 Toggles noclipping mode on/off. This is a cheat.
See also: sv_cheats

nofilecompression
(cvar: boolean)
default: 0
 This is a debugging cvar used to disable file compression. You should leave
 it set to 0.

noise
(cvar: boolean)
default: 0
 When set to 1, the current status of all sound channels is displayed on
 the screen.
See also: snd_channels

notarget
(command)
 Toggles notarget mode on/off. While active, monsters will not target you
 unless you hurt them first. This is a cheat.
See also: sv_cheats

pause
(command)
 Pauses or unpauses the game depending on whether or not it is currently
 paused.

pings
(command)
 This lists a very rough estimate of the speed of the connection between
 your machine and any others in the game. In reality, the values printed by
 this command aren't even pings; they're just the number of milliseconds
 that have passed since the last time you received a network packet from the
 other machines.

playdemo <demo>
(command)
 Plays a demo. The demo can be a file on disk or a lump in a wad.
See also: timedemo

r_columnmethod
(cvar: number)
default: 1
 Selects which of two algorithms to use to draw vertical columns on the
 screen. Method 0 is the original algorithm used by DOOM and is best for
 a 486. Method 1 is a new algorithm optimized for modern processors, and
 can as much as double the framerate on post-Pentium processors. (On 486s,
 it can drop the framerate by at least half.)

r_detail
(cvar: number)
default: 0
 This cvar selects the detail level of the view window. Valid values are:
    0. Normal detail level. Equivalent to Doom's high detail mode.
    1. Double pixels horizontally. Equivalent to Doom's low detail mode.
    2. Double pixels vertically.
    3. Double pixels horizontally and vertically.
 Doubling pixels horizontally offers more of a speed-up than doubling them
 vertically does.

r_drawflat
(cvar: boolean)
default: 0
 When set to 0, segs will be drawn as solid colors instead of textures.
 This is useful if you want to see how a node builder split a level's
 linedefs. Otherwise, it just looks ugly.

r_drawfuzz
(cvar: boolean)
default: 1
 When set to false, the "fuzz" effect on spectres and partially invisible
 players will be replaced with translucency.

r_drawplayersprites
(cvar: boolean)
default: 1
 When zero, the game will not draw the player's weapon or muzzle flash.

 String containing the width and height of the current view window. This
 cvar is read only.
See also: sizeup, sizedown, screenblocks

removebots
(command)
 Removes any bots from the game. Bots will also be automatically removed from
 network games when the arbitrator quits.

say <message>
(command)
 Sends a <message> to everyone playing.
See also: messagemode, messagemode2, say_team

say_team <message>
(command)
 Sends a <message> only to other members of your team. If teamplay is zero
 or you aren't on a team, then this command will act just like say and send
 the message to everyone.
See also: messagemode, messagemode2, say, team, teamplay

screenblocks
(cvar: integer)
default: 10
 This cvar determines the size of the view window. Valid values are in the
 range 3-12 inclusive. Attempts to set this cvar to values outside this
 range will be truncated. 3 is the smallest view window, and 12 is full
 screen. 11 is also full screen, but includes a small heads-up display.
See also: sizeup, sizedown, r_viewsize

screenshot [file]
(command)
 Dumps a copy of the screen to disk as a .pcx file. If [file] is not
 specified, the screenshot will be saved to the directory the game was run
 from with a name of the form doom????.pcx.

set <cvar> <value>
(command)
 Sets <cvar> to <value>. If <cvar> does not exist, it will be created.
See also: get

setcolor <cvar> <color name>
(command)
 Sets <cvar> to a color value specified in the X11R6RGB lump. (This is the 
 X11R6.rgb file from a standard X-Windows system.) If <color name> cannot
 be found, the contents of <cvar> are left unchanged. The file colors.txt
 included with the ZDoom archive contains a list of all the color names
 listed in zdoom.wad.
See also: all the am_* cvars, dimcolor

show_messages
(cvar: boolean)
Default: 1
 When this variable is non-zero, game messages will be displayed at the top
 of the screen. Regardless of the state of this cvar, console messages will
 always be displayed in the console and also written to disk if logging is
 enabled.

sizedown
(command)
 Decreases the size of the view window.
See also: screenblocks, sizeup

sizeup
(command)
 Increases the size of the view window.
See also: screenblocks, sizedown

skill
(cvar: integer)
default: 2
 This variable contains the game skill, ranging from 0 to 4 inclusive.
 Changes to this cvar only take effect when a new level is loaded.

skin
(cvar: string)
default: "base"
 This is your player's skin. Any skins you want to use or see need to be
 loaded at the command line with the -file parameter. "Base" is the name of
 the regular Doom marine and is always available. When (if?) I get
 client/server working, I will use a better mechanism where you can just
 throw the skins in a directory and use them without having to worry about
 specifying them at the command line.
See also: color, gender, name, skins, team

skins
(command)
 Lists the names of the skins that were loaded when the game was started.
See also: skin

snd_channels
(cvar: integer)
default: 8
 This cvar determines the number of channels used for mixing sound effects.
 Larger values generally sound better but also require a faster processor.
 In general, anything between 8-16 should be plenty.

snd_listmididevices
(command)
 This command lists the MIDI devices available in the system. Devices in
 this list can be used in the snd_mididevice cvar to select which device
 plays music.
See also: snd_mididevice, snd_midivolume

snd_mididevice
(cvar: integer)
default: -1
 This cvar determines which MIDI device ZDoom uses for MIDI and MUS music.
 A value of -1 indicates to use the Windows MIDI Mapper, while other
 values select specific MIDI devices. A complete list of MIDI devices
 available can be obtained with the snd_listmididevices command.
See also: snd_listmididevices, snd_midivolume

snd_midivolume
(cvar: number)
default: 0.5
 This is the volume at which MIDI and MUS music is played and can range
 from 0.0-1.0. 
See also: snd_musicvolume, snd_sfxvolume

snd_musicvolume
(cvar: integer)
default: 9
 This is the volume at which MOD music is played and can range from 0-64
 inclusive. Note that setting this near its maximum will probably result in
 nasty distortions of the music.
See also: snd_midivolume, snd_sfxvolume

snd_pitched
(cvar: boolean)
default: 0
 When set to true, the random pitch effect found in early version of Doom
 will be simulated.

snd_samplerate
(cvar: integer)
default: 44100
 This is the sampling rate at which sounds are mixed in the game. The value
 in this cvar will only take effect when MIDAS is restarted (usually when
 the game first starts). If you do not play MOD music from within the game,
 you can set this as low as 11025 without experiencing much perceptable
 loss of sound quality.

snd_sfxvolume
(cvar: integer)
default: 8
 This is the volume at which sound effects are played and can range from
 0-15 inclusive.
See also: snd_midivolume, snd_musicvolume

snd_surround
(cvar: boolean)
default: 1
 When true, selected sounds will be played on the surround channel. The
 effect is even noticable if (like me) you don't have special hardware
 to decode it. If you think it's annoying or you have a buggy soundcard
 that mixes in stereo but outputs in mono, you can turn this off.

splashfactor
(cvar: number)
default: 1.0
 This controls the amount of damage players receive when they fire a rocket
 and it explodes right next to them. It applies only to the player who fires
 the rocket; all others receive normal damage. A value of 0.5 would apply
 only half damage to the player. A value of 2.0 would apply double damage.
 Other values are similar. Useful mostly for people who like to rocket
 jump and don't like dying if they don't have 100% health and a lot of
 armor.

soundlinks
(command)
 Lists the links between different sounds that use the same sound lump.
 Links are generated dynamically while you play, so it is possible for this
 command to give different results in different games and even at different
 times during the same game.
See also: soundlist

soundlist
(command)
 Lists all the sounds defined and the lumps that they alias to. Unlike
 regular Doom, ZDoom refers to sounds using a long name and uses a SNDINFO
 lump to map those to the lumps in a WAD file that contain the actual
 sounds. Long names that refer to the same sound lump will have links
 generated as necessary to avoid actually loading multiple copies of the
 same sound into memory.
See also: soundlinks

spynext
(command)
 During a cooperative game or while watching a multiplayer demo, this
 command will switch the view to the next player.
See also: spyprev

spyprev

 During a cooperative game or while watching a multiplayer demo, this
 command will switch the view to the previous player.
See also: spynext

st_scale
(cvar: boolean)
default: 0
 When this cvar is true, the status bar will be scaled so that it covers
 the entire width of the screen in higher resolutions. This may look
 somewhat ugly, but it should be easier to read on high resolutions with
 smaller monitors.

stat [page]
(command)
 Displays profiling information. When used alone, displays a list of
 available displays. Use one of those as the page parameter to toggle
 the display on and off.
    stat fps : Time spent rendering the scene (not the same as vid_fps 1)
    stat bots : Time spent doing bot-related activities
    stat think : Time spent running all thinkers

stop
(command)
 Stops demo recording and exits the game.

sv_cheats
(cvar: boolean)
default: 0
 When non-zero, cheats will be allowed in Nightmare difficulty and network
 games. For purposes of fairness, this cvar can only be set from the
 command line when you run ZDoom. This is to avoid situations where the key
 player in a multiplayer game (player 1) could go to the console and type
 something like this:
    sv_cheats 1
    god
    sv_cheats 0
 whereby rendering himself immune to the attacks of others.
See also: give, god, noclip, notarget, idclev

sv_friction

default: 800
 This is the overall gravity of the entire level. 800 is normal gravity.

team
(cvar: string)
default: ""
 This is the team that your player belongs to.
See also: teamplay, say_team, messagemode2

teamplay
(cvar: boolean)
default: 0
 When set to "1", players will be recognized by team. Otherwise, everyone
 is treated as if they aren't on a team regardless of the settings of their
 team cvars. Useful primarily for the friendy fire avoidance dmflag and
 say_team command.
See also: dmflags, say_team team

testblend <color> <amount>
(command)
 Sets the palette blend to a specified color and amount. <color> can be
 either a color name defined in the X11R6RGB lump or a color string.
 <amount> can be a number between 0.0 and 1.0 inclusive and specifies how
 much of <color> should be mixed with the palette, with 0.0 being no mixing
 and 1.0 being full mixing.
See also: testcolor, testfade

testcolor <color>
 Sets the light color of any sectors using the default light to <color>.
 <color> can be either a color defined in the X11R6RGB lump or a color
 string.
See also: testblend, testfade

testfade <color>
(command)
 Temporarily sets the fade color of the current level to <color>. Most
 levels fade to black by default, but this can be changed with the MAPINFO
 lump. <color> can be either a color defined in the X11R6RGB lump or a
 color string.
See also: testblend, testcolor

testgibs
(cvar: boolean)
default: 0
 Does nothing.

ticker
(cvar: boolean)
default: 0
 When true, draws a series of dots at the bottom of the screen representing
 the number of tics it took to display the current frame. (One tic is
 1/35th of a second.) When -devparm is specified on the command line, this
 cvar is automatically set to "1". You can get a rough idea of your fps by
 counting the number of lit dots and dividing that from 35. A better way
 would be to use vid_fps.
See also: vid_fps

timedemo <demo>
(command)
 Plays a demo as fast as the refresh rate will allow and displays the
 average framerate attained during playback. For stability reasons, this
 command will also exit the game when the demo finishes.

 this and "toggle show_messages" is that this command always displays a
 message describing the current state of messages.
See also: show_messages, toggle

turn180
(command)
 Quickly turns your player around 180 degrees.

transsouls
(cvar: number)
default: 0.75

 are in the interval (0.0,1.0]. Large values mean less translucency.

turbo
(cvar: number)
default: 100
 This cvar effects how quickly the player moves. A value of 100 will cause
 the player to move at normal speed, 200 will cause the player to move at
 200% of normal speed, 50 will cause the player to move at 50% of normal
 speed, etc. Valid values range from 10 to 256.

unbind <key>
(command)
 Removes a binding from the specified key.
See also: bind, doublebind, unbindall, undoublebind

unbindall
(command)

 When this cvar is true, the game will refresh the palette every time
 the screen is redrawn. This can be useful with some buggy video drivers.

vid_winscale         (Linux only)
(cvar: number)
default: 1.0
 Controls how large the display is scaled when playing in an X window.
 Values of 1.0 and 2.0 are fast, other values use slower, generic scaling.
