- Helpfile:
- ---------
- The following options are allowed:
-
- [-blocks n]
- Specifies the number of blocks.
- [-delay n]
- Specifies a delay; 0 <= n <= 10
- [-tanks n]
- Specifies the number of tanks.
- [-missiles n]
- Specifies the number of missiles.
- [-salvos n]
- Specifies the number of salvos that the player receives.
- The default is the maximum of ntanks or nmissiles.
- [-landers n]
- Specifies the number of landers.
- [-original]
- Sets defaults to the original arcade version. This option
- overrides all options other than [-quiet] [-delay n].
- [-scores]
- Prints out the scores.
- [-version]
- Prints out the version.
- [-coptersonly]
- A practice mode involving only helicopters.
- [-nooutput]
- Game will generally not produce text output to a tty. Useful
- when running the game from a menu.
- [-quiet]
- Do not ring the bell during the game.
- [-cursor]
- A cursor is provided. Typically only useful if extreme pointer
- motion will take you out of the window. This circumstance can
- occur w/ multiple displays or virtual root windows. Newer
- versions of the game will attempt to confine the cursor to the
- game window.
- [-mono]
- Run the game in mono, even on a color screen. This option really
- runs the game in white on black. There are methods for running
- two-tone games w/ various bg's and fg's....see XResources below.
- [-defaultcolormap]
- On color displays, use the default color map. The game will
- still try to use as many colors as possible, but will not
- allocate a private colormap to do so.
- [-nofullscreen]
- Run the game in a window just large enough to play in. This
- option works well under some conditions, such as playing in mono
- or when using the default color map. Otherwise, when using a
- private colormap, the border tends to change to some unintended
- color (probably yellow).
- [-help]
- Prints this message.
-
- Keyboard commands:
- 'p' - pause
- 'c' - continue
- 'i' - pause and iconify (also spacebar)
- Only under R4 or later. Window managers are free to ignore this.
- 'q' - quit (also ^C, also 1st and 3rd button down simultaneously)
- 'r' - redraw
-
- General Information
- -------------------
- Cbzone is a version of Battlezone derived from the Fortran
- sources written by Justin S. Revenaugh. This version is more
- flexible in that the number of opponents is user selectable.
-
- Input to the the game is primarily through the mouse, although
- some keyboard commands are accepted. Mouse left button will
- fire a salvo; mouse right button will switch between low/high
- sensitivity (sensitivity determines how sensitive the joystick is to
- pointer motion). On a three button mouse, the middle button will
- center the joystick and stop your tank. This facility can be done
- ona two button mouse by hitting both buttons at the same time.
- Directional control of the tank is by moving the mouse to
- different portions of the screen. The joystick in the lower right
- hand of the screen will correspond to your tanks current movement
- and rotation.
-
- Scores are only eligible for the high score list if they
- are played with the default options with the exceptions that
- the delay can be 0-5 and quiet mode can be on.
-
- Options settable via XResources
- -------------------------------
- The following resources can be modified to control the game. These
- changes can be made via xrdb or on the command line using "-xrm".
-
- The game class is "Cbzone".

- Example Use of Resources
- ------------------------
- In general, the following commands will do something useful only a
- color screen.
-
- % cbzone -tanks 3 -xrm "*EnemyColor: magenta"
- this command would make all enemies (tanks, supertanks, missiles,
- and copters) magenta. Additionally, there would be 3 tanks or
- supertanks in the game.
-
- % cbzone -xrm "*tankcolor: black" -xrm "*supercolor: black"
- this is stealth mode, assuming a black background. All tanks
- and supertanks are black. However, they will still show up
- on the scanner.
-
- % cbzone -xrm "*fadingcolors: 5"
- For the objects which fade (blocks, landers, or enemies), there
- will be this many shades of a particular color. The default is
- as many as possible.
- For no fading colors, use -xrm "*fadingcolors: 1"
-
- % cbzone -xrm "*maxcolors: 20"
- Use only 20 colors. The game would generally try to obtain as
- many colors as it can either from the default colormap or by making
- its own colormap. If there are not enough color cells available,
- the game will reduce the number of different colors. The steps
- taken to reduce the number of colors is to first try and reduce the
- number of fading colors; if this is not sufficient, the game
- then starts changing groups of objects to the same color.
-
- % cbzone -xrm "*maxcolors: 2" -xrm "*fgcolor: skyblue"
- This command would run the game w/ a black (default) background;
- everything else would be skyblue.

- PAGER - which pager to use to read the message-of-the-day and the
- helpfile.

- Bugs
- ----
- Tanks currently move through one another, consider it a
- feature. Anything else is probably really a bug and should
- be reported.

- Author
- ------
- Justin S Revenaugh, MIT, wrote the original Fortran version.
- Todd W Mummert, mummert+@cs.cmu.edu, CMU, translated to C,
- added variable number of objects and greater color support.
