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 joystick.

       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 keyboard.

ENVIRONMENT

       The following environment variables are used.

              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

       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. Disabled 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 default 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. Defaults 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

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

viewGamma
Sets the gamma used when loading the PNG images used for sprites. Defaults to 1.1.

audioType
Sets which audio backend to use. The desired backend must be compiled 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. Defaults 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.
