This is a version of Battleships played on a 10x10 grid, with you
|
||
|
|
playing against the computer. There's a reasonable amount of onscreen
|
||
|
|
help, so you should be able to figure out how to work it pretty
|
||
|
|
quickly.

|
It's a port of a Unix curses version hacked by a few different people.
|
||
|
|
A formatted version of the man page (documentation) is given below,
|
||
|
|
and the 'readme' from the last person to hack it is in 'esr.txt'.

DESCRIPTION
|
||
|
|
This program allows you to play the familiar Battleships
|
||
|
|
game against the computer on a 10x10 board. The interface
|
||
|
|
is visual and largely self-explanatory; you place your
|
||
|
|
ships and pick your shots by moving the cursor around the
|
||
|
|
`sea' with the rogue/hack motion keys hjklyubn. If your
|
||
|
|
UNIX has a modern (non-BSD) curses, your arrow keys will
|
||
|
|
also work.
|
||
|
|
|
||
|
|
Note that when selecting a ship to place, you must type
|
||
|
|
the capital letter (these are, after all, capital ships).
|
||
|
|
During ship placement, the `r' command may be used to
|
||
|
|
ignore the current position and randomly place your cur-
|
||
|
|
rently selected ship. The `R' command will place all
|
||
|
|
remaining ships randomly. The ^L command (form feed, ASCII
|
||
|
|
12) will force a screen redraw).
|
||
|
|
|
||
|
|
The command-line arguments control game modes.
|
||
|
|
|
||
|
|
-b selects a `blitz' variant
|
||
|
|
-s selects a `salvo' variant
|
||
|
|
-c permits ships to be placed adjacently
|
||
|
|
|
||
|
|
The `blitz' variant allows a side to shoot for as long as
|
||
|
|
it continues to score hits.
|
||
|
|
|
||
|
|
The `salvo' game allows a player one shot per turn for
|
||
|
|
each of his/her ships still afloat. This puts a premium
|
||
|
|
scoring hits early and knocking out some ships and also
|
||
|
|
makes much harder the situation where you face a superior
|
||
|
|
force with only your PT-boat.
|
||
|
|
|
||
|
|
Normally, ships must be separated by at least one square
|
||
|
|
of open water. The -c option disables this check and
|
||
|
|
allows them to close-pack.
|
||
|
|
|
||
|
|
The algorithm the computer uses once it has found a ship
|
||
|
|
to sink is provably optimal. The dispersion criterion for
|
||
|
|
the random-fire algorithm may not be.
