NAME
prboom-plus.cfg - Configuration file for PrBoom+
USAGE
When a version of PrBoom+ is run, it searches for this configuration file to modify its
default settings. Every time PrBoom+ exits, it rewrites the configuration file, updating
any settings that have been changed using the in-game menus.
PrBoom+ expects the config file to be ~/.prboom-plus/prboom-plus.cfg. Alternatively, it
can be made to look elsewhere by using a command-line parameter:
prboom-plus [-config myconf]
FORMAT
prboom-plus.cfg consists of a number of variables and values. Each line is of the
following format:
{ {{# | ; | [} comment_text} | { variable {decimal_integer | 0xhex_integer |
"string_text"}} }
Any line beginning with a non-alphabetic character is treated as a comment and ignored;
for future compatibility you should start comments with a #, ; or [. Note however that
when PrBoom+ rewrites prboom-plus.cfg it does not preserve user added comments.
Any line beginning with an alphabetic character is treated as a variable-value pair. The
first word (sequence of non-whitespace characters) is the variable name, and everything
after the following block of whitespace is taken to be the value assigned to the variable.
Variables not recognised by PrBoom+, or which are given an invalid value or a value of an
inappropriate type, are ignored. Warning messages are given where relevant.
The variables recognised by PrBoom+ are described per-section in the following sections.
The sections are informal however; when PrBoom+ rewrites the config file it writes in
section headings and puts variables into the relevant sections, but when reading these are
ignored.
MISC SETTINGS
compatibility_level
PrBoom+ is capable of behaving in a way compatible with earlier versions of Doom
and Boom/PrBoom[+]. The value given here selects the version to be compatible with
when doing new games/demos. See README.compat for details.
realtic_clock_rate
Selects the speed that PrBoom+ runs at, as a percentage of normal game speed.
Leave at 0 unless you want to experiment. Note that it is considered `cheating' to
use this at any setting below or above 0.
max_player_corpse
Sets the maximum number of player corpses to leave lying around. If this limit
would be exceeded, an old corpse is removed. Useful for big/long Deathmatch games,
where the sheer number of corpses could slow the game down.
flashing_hom
Flag indicating whether a flashing red background is drawn to highlight HOM (Hall
of Mirrors) errors in levels (for level developers).
demo_insurance
Selects a method of protecting demos against `going out of sync' (where the player
seems to lose control and behave madly, but in fact the players original
instructions as stored in the demo have got out of sync with the game he was
playing). 0=No protection, 1=Full protection, 2=Only while recording demos. Safest
when left set to 2.
endoom_mode
This parameter specifies options controlling the display of the credits screen when
Doom exits. Currently it is the sum of 3 options: add 1 for colours, 2 for non-
ASCII characters to be displayed, and 4 for the last line to be skipped so the top
line doesn't scroll off screen.
level_precache
If set, when loading a new level PrBoom+ precaches all the graphics the level is
likely to need in memory. This makes it much slower to load the level, but reduces
disk activity and slowdowns reading data during play. Most systems are fast enough
that precaching is not needed.
FILES SETTINGS
wadfile_1, wadfile_2
The names of 2 .wad files to be automatically loaded when PrBoom+ is started. A
blank string means unused.
dehfile_1, dehfile_2
The names of 2 patch files (.deh or .bex) to be automatically loaded when PrBoom+
is started (empty string for none).
GAME SETTINGS
default_skill
The default skill level when starting a new game.
weapon_recoil
Enables recoil from weapon fire.
doom_weapon_toggles
Flag indicating whether pressing 3 or 1 when that weapon is already selected causes
the selected shotgun or fist/chainsaw to be toggled, as in original Doom. Some
people prefer to use a number for each weapon alone.
player_bobbing
Enables player bobbing (view moving up/down slightly as the player runs).
monsters_remember
Makes monsters remember their previous enemy after killing their current target.
monster_infighting
Whether monsters will fight each other when they injure each other accidentally.
monster_backing
Whether monsters without close combat weapons will back away from close combat
(unlike original Doom).
monster_avoid_hazards
Whether monsters avoid crushing ceilings.
monkeys
Whether monsters will climb steep stairs.
monster_friction
Whether monsters are affected by changed floor friction (they should be, but
weren't in Boom).
help_friends
Whether monsters will help out injured monsters by aiding them against their
attacker.
player_helpers
The number of helper dogs to spawn.
friend_distance
Distance within which friends will generally stay.
dog_jumping
Whether dogs will jump.
sts_always_red
PrBoom+ can make the colour of the text displays on the status bar reflect your
current status (red=low, yellow=average, green=good, blue=super-charged). This
option if set selects the traditional Doom behavior of always-red status bar
display; set to 0 to allow the coloured display.
sts_pct_always_gray
See above, this makes just the percent signs always gray, instead of changing
colour.
sts_traditional_keys
Doom and Boom have two types of keys; PrBoom+ will normally display both keys of a
given colour if you have both. This option, if enabled, instead makes PrBoom+ only
ever display one key of each colour, in the same way Doom did.
traditional_menu
Changes PrBoom+'s menu ordering to be the same as original Doom if enabled.
show_messages
When enabled, text messages are displayed in the top left corner of the screen
describing events in the game. Can be toggled in the game, this is just to preserve
the setting.
autorun
Makes the player always run, without having to hold down a run key. Can be toggled
in the game, this just preserves the setting.
SOUND SETTINGS
sound_card
Selects whether sound effects are enabled (non-zero enables). For compatibility
reasons with Boom, a range of values are accepted.
music_card
Selects whether in-game music is enabled (non-zero enables). For compatibility
reasons a range of values are accepted.
pitched_sounds
If enabled by this variable, this enables `pitching' (making pitch adjustments to
the playing sounds) for 16 bit sound cards.
samplerate
The samplerate for soundmixing and timidity. The sound quality is much better at
higher samplerates, but if you use timidity then higher samplerates need much more
CPU power. Useful values are 11025, 22050, 44100 and 48000.
sfx_volume
Sound effects volume. This is best adjusted in the game.
music_volume
Music volume. This is best adjusted in the game.
mus_pause_opt
Selects what PrBoom+ does to the music when a games is paused. 0=stop the music,
1=pause the music (stop it playing, but when resumed resume it at the same place -
not implemented), 2=continue playing.
sounddev, snd_channels, soundsrv, musicsrv
These variables are no longer used by PrBoom+, but are kept for compatibility
reasons.
COMPATIBILITY SETTINGS
These are settings that let you choose whether the normal game mechanics are used, or
whether various quirks, bugs and limitations of the original Doom game are emulated.
VIDEO SETTINGS
screen_width, screen_height
For versions of PrBoom+ which support high-res, these specify the default screen or
window size for PrBoom+. These settings are ignored and preserved by versions of
PrBoom+ which do not do high-res (they assume 320x200).
use_fullscreen
If set, this causes PrBoom+ to try to go full screen. Depending on your video
driver and mode, this may include changing screen resolution to better match the
game's screen resolution.
use_doublebuffer
Use double buffering to reduce tearing. On some machines this is even faster than
the normal method, but on others this makes problems, so you have to try out which
setting works best.
translucency
Causes PrBoom+ to display certain objects as translucent.
tran_filter_pct
Selects how translucent objects are when they are translucent. Play with this and
see for yourself.
screenblocks
Selects a reduced screen size inside the PrBoom+ window (the player's view is
surrounded by a border). Normally this is undesirable, but it can help speed up the
game. Can be changed in the game with the +/- keys, this variable is just to
preserve that setting.
usegamma
Selects a level of gamma correction (extra screen brightening) to correct for a
dark monitor or light surroundings. Can be selected in the game with the F11 key,
this config entry preserves that setting.
OPENGL SETTINGS
If you are knowledgeable about OpenGL, you can tweak various aspects of the GL rendering
engine.
gl_nearclip
The near clipping plane *100.
gl_colorbuffer_bits
The bit depth for the framebuffer. (16, 24 or 32 bits).
gl_depthbuffer_bits
The bit depth for the z-buffer. (16, 24 or 32 bits).
gl_tex_filter_string
A string, one of the following: GL_NEAREST or GL_LINEAR (no mipmapping), or one of
GL_NEAREST_MIPMAP_NEAREST, GL_NEAREST_MIPMAP_LINEAR, GL_LINEAR_MIPMAP_NEAREST,
GL_LINEAR_MIPMAP_LINEAR with mipmapping.
gl_tex_format_string
One of the following strings: GL_RGBA - means format selected by driver (not so
good), GL_RGBA2 - means 2 bits for each component (bad), GL_RGBA4 - means 4 bits
for each component (like GL_RGBA on most cards), GL_RGB5_A1 - means 5 bits for each
color component 1 bit for the alpha channel (default), GL_RGBA8 - means 8 bits for
each component (best quality, but only a little bit better than GL_RGB5_A1 and
slower on most cards).
gl_drawskys
If 0, disables drawing skies, which may be needed with some problematic 3D cards.
gl_sortsprites
Experimental option, possibly faster but less reliable.
MOUSE SETTINGS
This section specifies settings for using a mouse with PrBoom+. There are several settings
that control button bindings (what action each button causes in the game); these are
easiest set from the in-game menus, these config entries are to preserve the settings
between games.
use_mouse
Enable or disable the use of a mouse with PrBoom+.
mouse_sensitivity_horiz, mouse_sensitivity_vert
Sets the sensitivity of the mouse in PrBoom+. Easier set from the in-game menus.
KEY BINDINGS
These specify the keys that trigger various actions in PrBoom+. The codes used for keys
are internal to PrBoom+, though many keys are represented by their ASCII codes. It is
easiest to modify these via the in-game menus (OPTIONS->SETUP->KEY BINDINGS). These config
file entries preserve the settings from this menu between game sessions.
JOYSTICK SETTINGS
There are the trigger variables here, which are calculated during joystick calibration
(the values received from the kernel driver outside of which movement is caused in the
game). Also there are the button-bindings, again best adjusted using the in-game menus.
use_joystick
This selects the number of the joystick to use, or 0 selects no joystick. You have
to have the relevant device files (/dev/js0 etc) and the kernel driver loaded.
CHAT MACROS
These are pre-written text strings for quick transmission to players in a network game
(consult your Doom documentation). Easiest set via the in-game menus (OPTIONS->SETUP->CHAT
MACROS).
AUTOMAP SETTINGS
These are settings related to the automap. These are easiest set from within the game.
HEADS_UP DISPLAY SETTINGS
These are settings related to the heads-up display, that is messages received while
playing and the heads-up display of your current status obtained by pressing + while the
view is full-screen in PrBoom+. See the Boom documentation for details. All controlled
best from within the game.
WEAPON PREFERENCES
Here are the settings from the Weapons menu in the game (OPTIONS->SETUP->WEAPONS).
