NAME

     doomsday - Enhanced source port of Doom, Heretic and Hexen

SYNOPSIS

     doomsday [-iwad dir] [-game id] [-wnd] [-wh w h] [-file file ...]

     Everything following -- is ignored.  @ can be used to specify a response file whose contents
     are added to the command line.

OPTIONS

           -file | -f      Specify one or more data files or packages (.pack, PK3, WAD, LMP) to
                           load at startup. When used together with the -game option, the
                           specified files will be loaded at startup. Without -game they are just
                           registered as available files that can then be loaded in games. It is
                           also possible to load data files at runtime by opening the Packages
                           sidebar (see TASK BAR) or with the load console command.

           -game | -g      Sets the game to load after startup. If omitted, the Home screen will
                           be shown after startup. See GAMES for a list of available games. For
                           example: -game doom1-ultimate

           -h | -? | --help
                           Prints a brief list of the command line options.

           -iwad           Specifies a directory where to look for IWAD files. Searches for IWADs
                           from all known games and automatically loads them when needed.

           -version        Show version information.

           -wnd | -window  Starts in windowed mode. The default is to start in fullscreen mode.

           -wh             Sets the size of the Doomsday window. In fullscreen mode specifies
                           which display resolution to use.

   Additional Options
           -center         Center the window (when not in fullscreen mode).

           -command | -cmd
                           Execute a console command during startup. Multiple commands can be
                           joined together with semicolons. Note that console variables have game
                           plugin specific values, so if you change cvar values using this option
                           without loading a game (with -game), your values will be overwritten
                           when a game plugin is loaded.

           -connect        Attempts to connect to the server running at the given network
                           address. Equivalent to the console command connect.

           -devlog | -nodevlog
                           Enables or disables developer log entries. These are useful for
                           debugging and/or troubleshooting, but are too verbose or technical for
                           everyday use.

           -dpi            Set the UI pixel density. For example: -dpi 2.0

           -errors         Set the name of the error output file. The file is written to the
                           runtime folder. This output file is created in addition to the usual
                           doomsday.out. For example: -errors errors.out

           -fullscreen | -nofullscreen
                           Enable or disable fullscreen mode.

           -icd | -imusic | -isfx
                           Set the audio plugin for CD playback, music, and sound effects. The
                           following plugins are available:
                                 -   dummy
                                 -   fmod
                                 -   fluidsynth
                                 -   sdlmixer
                                 -   openal

           -fontsize       Set a scaling factor for UI fonts. This is applied separately from the
                           overall UI scale setting (see CONFIGURATION). For example: -fontsize
                           1.5

           -loglevel       Set the log output level. The levels are: XVerbose, Verbose, Message,
                           Note, Warning, Error, Critical.

           -maximize | -nomaximize
                           Maximize the window, or set the window to non-maximized mode.

           -noaudio        Disable all audio (sound effects and music).

           -noautoselect   Do not try to automatically select a game to load. Only has effect
                           when -game is not used. Doomsday will always start in the Home screen
                           or, when starting a server, not at all.

           -nodiscovery    Disable discovery of servers on the local network.

           -nofsaa         Disable antialiasing.

           -nogog          Disable detection of games from GOG.

           -nojoy          Disable gamepads and other game controllers.

           -nomouse        Disable mouse input.

           -nomusic        Disable music.

           -nosfx          Disable sound effects.

           -nosteam        Disable detection of games from Steam.

           -novsync        Disable vsync.

           -out            Set the name of the log output file. The file is always written to the
                           runtime folder. This option overrides the default doomsday.out.

           -parse | -p     Load and execute the specified file that contains console commands.
                           Behavior is similar to -command with the exception that the commands
                           are loaded from a file.

           -packs          Set additional folders where to find packages. Works similar to -iwad.

           -pkg            One or more identifiers of packages that are loaded when the -game
                           option is used to launch directly into a game.

           -reset          Reset the engine configuration to default values. In practice, this
                           just erases the contents of the persist.pack file that stores
                           configuration variables and UI state. The affected variables include,
                           for example, game window size and position, and log filter settings.

           -verbose | -v   Print verbose log messages. Specify more than once for extra
                           verbosity.

           -vvv            Enables all log messages (normal and developer, all levels).

           -warp           When starting directly into a game using -game, automatically also
                           jump to a specific map. The map can be specified either as the map
                           number, a pair of numbers (episode and map), or the map identifier
                           (e.g., "MAP12").

           -width | -height
                           Set the horizontal/vertical display resolution when in fullscreen
                           mode.

FILES

     Your runtime files are by default stored in a folder called ~/.doomsday/. The following
     noteworthy files and folders can be found inside:

           runtime/autoexec.cfg
                           Console commands to execute after loading the game with the -game
                           option.

           runtime/cache/  Cached data that helps Doomsday run faster. You can delete the
                           contents of this folder; Doomsday will recreate them automatically as
                           needed.

           runtime/configs/
                           Game profiles and saved values for console variables and control
                           bindings.

           runtime/doomsday.out
                           Log message output file.

           runtime/savegames/
                           Folder containing all saved games. Each game has its own subfolder for
                           saves.

   Additional Files
           /etc/doomsday/defaults
                           System-level default configuration. This is checked after
                           ~/.doomsday/defaults. For example:

                                 audio fluidsynth {
                                     driver: pulseaudio
                                 }

           /etc/doomsday/paths
                           System-level paths configuration (basedir, libdir, iwaddir). This is
                           checked after ~/.doomsday/paths. The syntax of the file
                           (https://manual.dengine.net/guide/configuration) is documented in the
                           wiki.

           ~/.doomsday/defaults
                           User's own defaults (similar to the system-level defaults; see above).

           ~/.doomsday/paths
                           User's paths configuration (basedir, libdir, iwaddir).

           /usr/share/doomsday/
                           Data files for the engine and game plugins.

ENVIRONMENT

     The following environment variables are recognized by Doomsday.

           DOOMWADDIR      Doomsday looks for WAD files in this directory.

           DOOMWADPATH     Delimited set of DOOM WAD directories. Use colon (:) to separate
                           directories. Supported WAD files are searched for in each directory.

INTRODUCTION

     The Doomsday Engine is a "source port" of id Software's Doom and Raven Software's Heretic
     and Hexen, which were popular PC FPS games in the early-to-mid 1990s. Doomsday enhances
     these classic games with many features including 3D graphics, fully customizable controls
     and client/server multiplayer, making them more accessible to modern gamers. However, the
     feel of the original games has been kept intact, ensuring sublime nostalgia or an exciting
     introduction to the pioneering games of the genre.

     Doomsday and the associated ports of Doom, Heretic and Hexen have been in development since
     1999; the first versions were released in late 1999 and early 2000. Several people have been
     involved in the project (see ACKNOWLEDGEMENTS).

GAMES

   Loading IWADs
     Doomsday requires IWAD files (http://wiki.dengine.net/w/WAD) to run games. You can use the
     following ways to let the engine know where your IWADs can be found:

              The first time you launch Doomsday and it doesn't find any IWADs, it will show a
               tab titled "Data Files?" containing a single button. Clicking the button opens a
               file dialog where you can pick a folder where your IWAD files are located.

              The directory /usr/share/games/doom is always checked for any recognized IWAD
               files.

              Using the -iwad command-line option. You can either provide the path to the IWAD
               to use, or the path of the directory under which IWADs are located. Doomsday will
               look through the specified location and use all the recognized IWADs
               automatically. In other words, you can have the IWADs for all games stored in a
               single directory; Doomsday will use the appropriate one for each launched game.

               -iwad will also accept multiple paths as parameters:

                     -iwad path1 path2

              The configuration file ~/.doomsday/paths is checked for iwaddir (see FILES).

              Environment variables DOOMWADDIR and DOOMWADPATH (see ENVIRONMENT).

              The configuration variable Config.resource.packageFolder. This is typically set
               automatically via the user interface, for instance when you first start Doomsday.
               Its value can also be manipulated in the Doomsday Script command prompt. (The
               variable Config.resource.recursedFolders determines if subdirectories should be
               searched.)

     Doomsday tries to recognize IWAD files based on their contents. The identification criteria
     can be viewed in GitHub (https://github.com/skyjake/Doomsday-
     Engine/blob/master/doomsday/apps/libdoomsday/net.dengine.base.pack/databundles.dei).

   Supported Games
     One game plugin, such as the Doom Plugin, is able to run many different variants of the
     game. Each variant emulates a specific version of the original game and typically has its
     own IWAD file.

     Below is a list of all the games supported by the game plugins distributed with Doomsday.

HOME SCREEN

     The Home screen in Doomsday 2 is a full replacement for the separate front-end application
     that was used in earlier versions. In Home you can manage your game library, resource packs
     and other add-ons, and join multiplayer games.

     Home consists of a number of scrollable tabs. There are several ways to navigate between
     tabs:

           -   Click on the tab names in the top of the screen.
           -   Left and right arrow keys move focus to an adjacent tab.
           -   Shortcut keys: D, H, X, O, M, and S (while not entering text in a text field.)
           -   Click on the left or right edge of the screen.

   Game Library
     The game library lists all the available games and their associated save files. Each game
     can be configured to load additional mods (WADs, PK3s, data files, resource packs). You can
     also add new customized games based on one of the built-in games.

     In User Interface settings you can hide entire game tabs, if you are not interested in a
     particular family of games. See CONFIGURATION for more details.

     Sorting games in the library. If you have lots of games available, it may be helpful to
     change the game library view options so you can more easily find the game you are looking
     for. Click on the "..." button under the tab title to see the view options.

     Starting a game with or without additional mods. Click on a game to select it, or move the
     selection with the arrow keys. When selected, Mods and Play buttons slide in. The Mods
     button shows a number for how many additional mods have been selected for loading. Click
     Play or double-click the game to start the game.

     Selecting mods. Click the game's Mods button to choose which additional mods are going to be
     loaded when the game is started. On the left side of the dialog, you have a list of the mods
     selected for loading. On the right, you can browse the available mods. The mods browser
     works similarly to the Mods tab, and it has a search field and Info buttons (see MODS). To
     add a mod to the game, click the Plus button or double-click the mod.

     Loading a saved game. All saved games are listed below the game they were created in. Click
     on a save to select it, and then press the game's Play button. Clicking on an already
     selected save will unselect it.

     NOTE:   Old savegames created with Doomsday 1.x do not contain information about which data
             files and mods were in use when the save was created, so Doomsday can't determine
             which game they belong to. Such saves are listed under each variant of the game.

     Savegame information. Right-click on a saved game to see information about the save: which
     data files and mods were in use, the overall game parameteres, current map, and other status
     information.

     Deleting a saved game. When a savegame is selected, a small X button appears next to it.
     Clicking the X lets you delete the save.

     Save folders. Each game is assigned a unique save folder where all the save files of the
     game are kept. Right-click on a profile and select "Show Save Folder" to open the folder in
     operating system file browser. Note that custom games created in version 2.0 or earlier
     share a save folder with the built-in game. You can use the "Create New Save Folder" menu
     item to create a new save folder for the custom game, but you will need to manually move the
     existing save files over there.

     Creating a custom game. At the bottom of each game tab, there is a Plus button that creates
     a new customized game. In the game settings, you can choose which game mode will be used,
     and which mods are selected for loading. Note that game cannot have a name that is identical
     to an already existing game in the library.

     Duplicate, edit, and delete games. Any game can be duplicated by right-clicking on it and
     selecting "Duplicate". Games can also be edited to change their name, the primary data file
     (IWAD), and the set of selected mods.

   Mods
     The Mods tab is used to browse the available mods and other packages. The Mods tab shows all
     the data files that Doomsday knows about. You can also quickly try out individual mods in
     one your games.

     Configuring the mod search folders. To let Doomsday know where your mods can be found,
     either select "Settings" in the Mods tab's actions menu (the "..." button under the tab
     title), or go to Data Files settings (see CONFIGURATION). The mods will not be copied or
     moved from wherever you keep them.

     Browsing mods. The mods list may contains hundreds of items, so you may want to find the
     mods you're looking for by entering some search terms. Enter the words to search for in the
     search field at the top of the list. The search is limited to metadata; the actual file
     contents are not accessed. When entering multiple words, only mods whose metadata contains
     all the words are shown.

     Special search keywords. Some search words have a special meaning:

              "gamedata": Primary game data files (IWADs).

              "hidden": Only mods that are normally hidden will be shown. Mods that are hidden
               by default include, for example, mods inside other packages that will get
               automatically loaded.

              "loaded": Only show currently loaded mods. This is useful when browsing mods while
               playing a game.

              "core": Doomsday's own core packages. These will be automatically loaded as
               needed.

     Viewing information about a mod. Right-click a mod or click on the "..." button to view
     information about it. In the case of WAD files, all the maps in the WAD are listed so you'll
     know which map to start when playing. The info popup also shows the game title picture found
     in the mod, and readme notes provided by the author. In some cases, Doomsday can make a
     guess about the game that the mod is meant to be used with.

     Quickly trying out a mod. One of the most useful features of the Mods tab is quickly loading
     a mod in one your games. This will make no changes to your existing games. Simply open the
     mod info popup (as explained above) and click on "Play in...". However, you should first
     check that the mod actually is compatible with the game you are playing. Also be aware that
     if you are already running a game, it will be unloaded first and any unsaved progress will
     be lost.

     Quickly adding a mod to a game. The "Add to..." button in the mod info popup will add the
     mod to one of your existing games. The games that already have the mod are tagged "ADDED" in
     the list.

     Configuring optional contents. Some mods have optional subcomponents. For instance, add-ons
     that use the Snowberry Box format may include both opt-in and opt-out mods. When viewing
     information about this kind of collections, an additional "Options" button is shown in the
     mod info popup. This will let you enable or disable individual contained mods.

   Multiplayer
     The Multiplayer tab lists multiplayer games that you can join. Servers on the local network
     are discovered automatically and are visible immediately in the Multiplayer games list. The
     dengine.net (http://dengine.net/) master server is also automatically queried for any public
     servers.

     Viewing server information. Right-click a server in the list to view information about it.
     The same popup can be opened by clicking the small "..." button in the server description.
     The status information includes:
           -   ping time
           -   which game and map is currently running
           -   outline of the current map
           -   list of mods loaded on the server
           -   list of connected players
           -   server version

     Joining a game. Join an open multiplayer game by clicking "Join" either in the server list
     or in the server information popup. Any missing mods are downloaded automatically after you
     click the button.

     Player name and color. When a game is running (after joining a multiplayer game or also in
     single-player), go to the game's "Options" menu and select "Player Setup". In this menu you
     can change your multiplayer name, player color, and (in Hexen) player class. Note that this
     is the game's own menu and not part of Doomsday's UI.

     Connecting to a non-public server. To connect to a server that is not announced to the
     master server, select "Connect to Server..." in the Multiplayer tab's actions menu ("..."
     under the tab title), and enter the server's IP address or domain name.

     Failure to connect? Connectivity problems can also be due to your firewall or network
     address translation (NAT) (https://en.wikipedia.org/wiki/Network_address_translation).
     Doomsday uses TCP network connections for multiplayer games. If you host a game and are
     behind a firewall or using NAT, you must make sure that other computers are able to open TCP
     connections to your computer. This entails opening the appropriate incoming TCP ports on
     your firewall and/or configuring the NAT so that the correct ports are routed to your
     computer.

     Additionally, UDP ports 13209-13224 are used for detecting servers running on the local
     network; if you are experiencing problems with autodetecting local servers, check that your
     firewall isn't blocking these UDP ports on either end.

     A server opens one TCP port for listening to incoming connections. The port must be open for
     incoming TCP traffic in the firewall. The port number is configured with the console
     variable net-ip-port. By default, a server uses TCP port 13209.

     Clients do not require any firewall configuration for incoming connections. A client only
     needs to be able to reach the server via the server's TCP port.

     You can see status information about the network subsystem with the console command:

           net info

     Hosting a game. Use doomsday-shell or doomsday-shell-text to host a multiplayer game of your
     own. The Shell allows you to start, stop, and control Doomsday multiplayer servers. This
     includes both your own local servers and remote servers on the internet.

     doomsday-server runs in a background process and has no UI of its own. The Shell provides a
     couple of basic game options that you can change via the GUI. For example, you can choose
     between Deatchmatch and Co-op mode, change the current map, and enable or disable monsters.
     The full set of console variables can be modified via the Console tab (text-mode command
     line interface).

     If your server is not public (i.e., announced to the master server), a client can connect to
     it manually using the IP address or domain name.

     For more information about the Shell, see Shell Help in the wiki
     (https://manual.dengine.net/Shell_Help).

TASK BAR

     The task bar is a central element of Doomsday's UI. It is available at all times and
     provides access to key features of the engine. For example, you can modify configuration
     settings, show the Home screen, and unload the current game.

     You can show the task bar by pressing Shift + Esc.

   App Menu
     The rightmost button in the task bar (with the DE logo) opens the Doomsday app menu.

     Tutorial. The first-run tutorial points out the basic features of Doomsday's UI. It is only
     shown once, but you can manually show it again by selecting "Help: Show Tutorial".

     Browsing and loading mods. "Browse Mods..." opens the mod browser in a sidebar where mods
     can be loaded and unloaded manually. You can also view information about mods like in the
     Home screen. The sidebar is only available when a game is loaded. You can use the "loaded"
     keyword to filter the list so that only the currently loaded mods are listed.

     NOTE:   Data from newly loaded mods may not be used until a new map is started in the game.
             Use of external textures can be enabled and disabled in Renderer settings.

     Checking for updates. Doomsday queries the dengine.net website to see if there are newer
     builds and shows a notification when updates are available. You can always also do a manual
     update check by selecting "Check for Updates".

     Clearing the resource cache. Some resources and metadata get cached for later access. This
     allows Doomsday to load the resources faster and operate more efficiently. Usually it is
     unnecessary to clear the cache manually. See FILES for the cache's location.

   Configuration
     The task bar's Gear button opens the configuration menu. This is where the majority of
     Doomsday's settings can be viewed and changed. Some of the settings are only available when
     a game is loaded ("Input", for instance).

     Reset to defaults and advanced settings. Many settings dialogs have a "Reset to Defaults"
     button. This affects only the settings in that one particular dialog. Sometimes a Gauge
     button is also available. It is reserved for advanced settings that are useful for
     developers and modding.

     Renderer settings. Most of the renderer settings are managed via appearance profiles. This
     makes it easy to select one of the presets, such as a vanilla look or more exaggerated
     effects. The dialog has a couple of general settings in addition to the active appearance
     profile. The "Pixel Density" slider is particularly useful as it allows improving rendering
     performance and achieving a more pixelated, 1990s VGA-style look. The selected appearance
     profile applies to all games.

     Some resource packs with high-resolution textures are intended to be used with the
     unmodified original games. However, a PWAD file may replace some of the textures with custom
     ones. The "External Images" options allow you to control when external images are actually
     enabled if the resource packs in use aren't compatible with the loaded PWADs.

     Renderer appearance sidebar. Click the Gear button next to the selected renderer appearance
     profile and select "Edit" or "View" to open the appearance sidebar. Alternatively you can
     open the sidebar with the rendedit console command. Individual settings groups can be folded
     and unfolded by clicking on the group titles. You can continue playing the game while the
     sidebar is visible. When you're done, dismiss the sidebar with the X button in the top right
     corner.

     Video aspect ratios. In addition to basic game window parameters, the Video settings dialog
     has a set of aspect ratio options. These control the aspect ratios applied to specific
     elements in the game:

           -   "Original 1:1": The aspect ratio is exactly as in the original game.
           -   "Smart": The aspect ratio is dynamic but does not stretch too far away from the
               1:1 ratio.
           -   "Stretched": The aspect ratio is unrestricted and adapts to window dimensions.
               Game elements may appear too wide or tall with this setting.

     Audio backend. Audio output capabilities vary based on operating system and audio hardware.
     Doomsday's audio backend can be configured according to your needs primarily via the
     selection of audio interface plugins. The recommendation on all platforms is FMOD for sound
     effects and FluidSynth for music, because these two enable software-based rendering of both
     3D sound effects and MIDI music. Some of the audio options are dependent on the active audio
     plugins. For example, a MIDI sound font is supported by the FMOD and FluidSynth plugins. 3D
     sound and reverb are supported by FMOD, OpenAL, and DirectSound. The audio backend can be
     reconfigured on the fly; any changes are applied when you press the "Apply" button.

     Game controllers. Doomsday comes with a few preset bindings for different gamepads. To use
     one of the presets, click on the "Game Controller Preset" button and select a suitable one.
     Then click "Apply" to erase all your existing game controller bindings and activate the ones
     in the preset. You can still manually edit the bindings in the game's "Options" menu.

     Mouse input settings. The "Sync Axis Sensitivities" option will ensure that mouse
     sensitivity is the same in both the horizontal and vertical directions.

     Minimizing mouse latency. The default input settings try to replicate the feel of the
     original 35 Hz input events of Doom. However, when the screen is actually refreshed at a
     higher rate, this may feel distractingly laggy. The 35 Hz limiter can be disabled in the
     advanced input settings (click the Gauge button). This will minimize mouse input latency as
     much as possible. You may additionally want to disable mouse filtering by toggling the
     "Filter X Axis" and "Filter Y Axis" options.

     Local multiplayer mods. By default, clients are not allowed to load mods in addition to what
     the server is using. This avoids any potential compatibility issues with the client's mods
     overriding some of the game's definitions. However, you can manually enable local mods in
     Network settings. You can then select additional local mods for multiplayer games in the
     server information popup before joining the game.

     User Interface settings. The "Scale" setting applies to the Doomsday UI only, and adjusts
     the overall size of UI elements and fonts. Lowering the UI scaling may be helpful for
     example when using a very low display resolution. In the Home screen there will be more tabs
     visible at the same time when using a smaller UI scale.

     Updater settings. The Updater settings determine when Doomsday will check for available
     updates. When an update is downloaded, it is saved to your temporary files folder.

   Log History and Log Options Menu
     The log message history panel slides in from the left edge of the view. When visible, you
     can drag its right edge to resize it.

     The leftmost button in the task bar opens the log options menu:

           Show Full Log   Expands the log history panel to its full size. When the task bar is
                           open, pressing PageUp will also expand the panel size.

           Close Log       Dismisses the log history panel.

           Go to Latest    Scrolls the log history to the latest message.

           Copy Path to Clipboard
                           Copies the doomsday.out file path to the system clipboard to make it
                           easier to find the output file.

           Clear Log       Deletes all log messages from memory. The doomsday.out file is
                           unaffected.

           Snap to Latest Entry
                           When this setting is enabled, new log entries will cause the history
                           panel to scroll to the latest entry (bottom of the list).

           Entry Metadata  When this setting is enabled, log entries will be prefixed with a
                           timestamp and categorization symbols.

           Log Filter & Alerts
                           Settings for filtering which log messages get printed. You can choose
                           filtering options individually for each engine subsystem. Developer
                           messages ("Dev") are primarily intended for developers and debugging,
                           so they are disabled by default. The "Alert" toggles cause warnings
                           and errors to pop up in the notification area.

   Command Prompt
     The middle of the task bar is occupied by a command prompt text field. Here you can enter
     console commands and modify console variables manually. This is typically most useful for
     developers, modders, and other advanced users.

     Console basics. Type help to get started. This prints some basic information about how to
     use the console, and commands for listing all the available console commands and variables
     (https://manual.dengine.net/consolevariable). At any time, press Tab to autocomplete the
     word being typed. This will pop up a list of all possible completions, including the current
     values for any variables. You can change console variable values as follows:

           rend-camera-fov 110

     Shortcut key. You should set up a console shortcut key if you find yourself going to the
     console often. The shortcut defaults to Tilde (U.S. keyboard) but you can choose your own
     shortcut key by clicking the ">" button next to the command prompt.

     Interactive Doomsday Script prompt. Doomsday Script is a fully-fledged Python/Ruby-like
     scripting language built into Doomsday 2. While it doesn't yet allow full access to all
     engine features, it is being improved in each release. The command prompt can be switched to
     Doomsday Script mode by right-clicking the ">" prompt menu button. Everything entered into
     the command prompt is then run as Doomsday Script. This mode is intended only for
     developers.

BUGS AND KNOWN ISSUES

     Doomsday remains a work in progress so there usually is a number of bugs and known issues.
