chromium-bsu(6) Games Manual chromium-bsu(6) NAME chromium-bsu - slick scrolling space shooter SYNOPSIS chromium-bsu [-fwv] [-na] [-nb] [-nt] [-V] [--fullscreen] [--window] [--vidmode <mode>] [--noaudio] [--noblend] [--notexborder] [--version] [--debug] DESCRIPTION chromium-bsu is a fast paced top down arcade style action shooter game. You progress through the game by destroying everything that you see on screen. There are a variety of 'power-ups' to assist you on the way. There is a big boss to destroy at the end of each level and there are various ships to destroy before you reach each boss. TIPS Do not let ANY enemy ships get past your fighters! Use your fighters as weapons! Strategic suicide is a powerful tactic! Self-destruct to preserve your ammunition! CONTROLS The input devices supported depend on the compile options used to build. You can control the ship with your mouse, keyboard (arrow keys) or joy- stick. To fire your weapons, hold the left mouse button, joystick buttons or the space bar. To pause the game, press pause or p on the keyboard. To blow up your ship, press enter/return or 0 twice or double right click. To switch to the next track in your music playlist, press n on the key- board. OPTIONS When run with arguments that are not understood, usage information is shown.

ENVIRONMENT The following environment variables are used. CHROMIUM_BSU_SCORE specifies the location of the user high-score file. CHROMIUM_BSU_DATA specifies the location of user-customised game data with the same layout and filenames as the system one. CHROMIUM_BSU_FONT When using the GLC backend, this specifies the font name to be used in the menu and the game if available. When using the FTGL backend, this specifies the path to the TTF font file used in the menu and the game. FILES The following files are used. ~/.chromium-bsu contains various user preferences. ~/.chromium-bsu-score contains the user high-scores. ~/.chromium-bsu-music contains a list of music to play during the game. ~/.chromium-bsu-data/ directory containing user-customized game data with the same layout and filenames as the system one. The game will also look in a system directory for data. CONFIGURATION The configuration file is a plain text file. Each line contains a key, a single-space separator and then a numeric value (integer or floating point). The following keys are recognised by the game. use_playList Enable/disable playlist support. This causes the game to open the ~/.chromium-bsu-music file and play the files listed there. Dis- abled by default. Only works when using OpenAL. use_cdrom Enable/disable CDROM support. This causes the game to attempt to play any audio CD that might be available. This is disabled by de- fault because the constant spinning up of the CD can be annoying and because CDs are less popular than MP3/OGG these days. Only works when compiled with SDL 1.X support. full_screen Enable/disable full-screen mode. This causes the game to fill the screen instead of just using a window. Disabled by default. Only works when using SDL support. true_color Enable/disable 24-bit color. When disabled it uses 16-bit color. Disabled by default. Only works when using SDL support. swap_stereo Enable/disable swapping sound orientation. Disabled by default. Only works when using OpenAL. auto_speed Use an alternate speed adjustment algorithm in certain situations. Disabled by default. Only works when using SDL support. show_fps Print the frames per second at the top right when in a game. De- faults to enabled. screenWidth The number of pixels wide to set the screen or window size. screenHigh The number of pixels high to set the screen or window size. screenSize Selects the screen or window size. Defaults to 800x600. This option is only exists for backwards compatibility purposes. It is replaced by the screenWidth and screenHeight options. 0 = 512 x 384 1 = 640 x 480 2 = 800 x 600 3 = 1024 x 768 4 = 1280 x 1024 gfxLevel Selects the desired amount of graphical effects. Defaults to full effects. 0 = minimal 1 = medium 2 = full gameSkillBase Selects the desired skill level. Defaults to normal. 0.2 = fish in a barrel 0.3 = wimp 0.4 = easy 0.5 = normal 0.6 = experienced 0.7 = fun 0.8 = insane 0.9 = impossible movementSpeed Speed that the ship moves around. The value shown in the menu is 1000 times the value in the configuration. Defaults to 0.03. maxLevel The maximum level that may be attempted. To attempt the next level you must first complete the maximum level. Defaults to 1. volSound Sets the volume of the sound effects. The value shown in the menu is 10 times the value in the configuration. Ranges from 0.0 to 1.0 and defaults to 0.9. volMusic Sets the volume of the sound effects.

Defaults to 1.1. audioType Sets which audio backend to use. The desired backend must be com- piled in for it to work, otherwise the other backend will be used. Defaults to OpenAL. 0 = OpenAL 1 = SDL Mixer textType Sets which text backend to use. The desired backend must be compiled in for it to work, otherwise the other backend will be used. De- faults to GLC. 0 = GLC 1 = FTGL cdromCount A cache of number of CDROM devices present, not used. cdromDevice The number of the CDROM device to use when use_cdrom is enabled. Zero-based.
