sopwith.cfg(5)

NAME
sopwith.cfg - configuration file for SDL Sopwith

DESCRIPTION

sopwith.cfg is the configuration file for sopwith(6). The settings stored in sopwith.cfg are usually modified in-game via the options menu.

sopwith.cfg is normally stored in the user's home directory, as ~/.local/share/SDL Sopwith/default.cfg. The path can be overridden using the XDG_DATA_HOME environment variable (see the XDG Base Directory Specification).

FILE FORMAT
The file is a plain-text file, consisting of a list of configuration options and their values, separated by whitespace. Each option is stored on a separate line.

For example:

    integer_value 1
    integer_value2 1

Lines beginning with "#" are interpreted as comments and will be ignored. Invalid lines or comments in the file will generate a warning, but will otherwise be ignored.

Some options are used for keyboard key bindings; these are stored as integer values containing the keyboard scan code of the key to be bound to. Boolean values are also stored as integers, with a value of zero usually indicating "false" and a non-zero value indicating "true".

CONFIGURATION VARIABLES

vid_fullscreen
    If 1, the game runs full screen rather than in a window. By default this is 0.

conf_solidground
    If 1, display the ground as a solid white block, reproducing the visual appearance of "Sopwith 1". If 0, the ground is displayed as a line, reproducing the visual appearance of "Sopwith 2". By default this is 0.

conf_video_palette
    Video palette to use for display. Valid values are 0 (CGA 1), 1 (CGA 2), 2 (CGA 3), 3 (Mono Amber), 4 (Mono Green), 5 (Mono Grey), 6 (Tosh LCD 1), 7 (Tosh LCD 2), 8 (Tosh LCD 3), 9 (IBM LCD), 10 (Tandy LCD), 11 (Gas Plasma) or 12 (Atari).

conf_hudsplats
    If 1, "splats" are shown on the screen when the plane takes damage: splatted birds are shown on the screen after a bird strike; windscreen "cracks" are shown if the plane is hit by bullets, and the whole screen turns magenta after flying through an ox. This feature was added by the original author of Sopwith in the "Network Edition" release. By default this is 0.

conf_wounded
    If 1, planes can take a single unit of damage without crashing. Your plane becomes slower to turn when wounded. This feature was added by the original author of Sopwith in the "Network Edition" release. By default this is 0.

conf_animals
    If 1, oxen and birds appear in the game. These were added in "Sopwith 2" but were not present in the original "Sopwith 1". By default this is 1.

conf_harrykeys
    If 1, the key_pullup and key_pulldown controls turn your plane relative to the screen, rather than your plane. It is a common point of confusion that the direction of turning appears to "reverse" when the plane is flipped / flying towards the left. By default this is 0.

conf_big_explosions
    If 1, oil tanks produce a huge explosion when destroyed. This reproduces the behavior found in both "Sopwith 1" and "Sopwith 2", but the magnitude of the explosion was dialed back significantly in the "Network Edition" release. The default is 1.

conf_medals
    If 1, medals are sometimes awarded to the player on return to base. Some details can be found in the "MEDALS" section of sopwith(6). The medals do not have any effect on gameplay. By default this is 1.

KEY BINDINGS
The following settings determine the in-game controls. These are keyboard scancodes, so the key binding does not change with keyboard layout. However, the name for the key as shown in the in-game options menu should match the current keyboard layout. The values for these settings are scancodes from the USB standard for HID devices.

key_accelerate
    Key to accelerate the plane. Default is "X" on a US layout keyboard.

key_decelerate
    Key to decelerate the plane. Decelerating too much may cause the plane to stall. Default is "Z" on a US layout keyboard.

key_pullup
    Key to pull up (aim the plane towards the sky). Default is "," on a US layout keyboard. Note that conf_harrykeys may change the behavior of this key binding.

key_pulldown
    Key to pull down (aim the plane towards the ground. Default is "/" on a US layout keyboard. Note that conf_harrykeys may change the behavior of this key binding.

key_flip
    Key to flip the plane upside down. Default is "." on a US layout keyboard.

key_fire
    Key to fire the machine gun. Default on a US layout keyboard is the spacebar.

key_dropbomb
    Key to drop a bomb. Default is "B" on a US layout keyboard.

key_home
    Key to autopilot the plane home to base. Default is "H" on a US layout keyboard.

HIDDEN SETTINGS
The following are "hidden settings": they cannot be edited in-game via the options menu, and editing the configuration file is the only way to change them.

snd_tinnyfilter
    If 1, a filter is applied to the sound output so that it sounds more like a tinny PC speaker that's inside a metal PC case. By default this is 1.

conf_missiles
    Enable missiles and starbursts (flares). This is a feature that was originally added by the author of Sopwith in the "Network Edition" release, but has been hidden as it significantly changes the gameplay in a way that doesn't fit the game's theme and also isn't particularly fun.

key_missile
    Fire missile, if conf_missiles is enabled. Default key is "V" on a US layout keyboard.

key_starburst
    Launch starburst (flare) if conf_missiles is enabled. Default key is "C" on a US layout keyboard.
