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.
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.
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.
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.
