|
||
|
|
|
||
|
|
CP/M port of the Unix game.
|
||
|
|
|

|
* bs.c - original author: Bruce Holloway
|
||
|
|
* salvo option by: Chuck A DeGaul
|
||
|
|
* with improved user interface, autoconfiguration and code cleanup
|
||
|
|
* by Eric S. Raymond <esr@snark.thyrsus.com>
|
||
|
|
* v1.2 with color support and minor portability fixes, November 1990
|
||
|
|
* v2.0 featuring strict ANSI/POSIX conformance, November 1993.
|
||
|
|
* v2.1 for Linux, October 1994.
|
||
|
|
* Slipstreamed in fixes to make it gcc -Wall clean, May '95.
|
||
|

|
I found it as part of the ZCN repository: https://github.com/jamesots/zcn
|
||
|
|
|
||
|
|
The C source has been modified for VT100 compatibility and some minor
|
||
|
|
changes have been made by me (Anna Christina Naß <acn@acn.wtf>.
|
||
|
|
|
||
|
|
bs.com is the compiled binary.
|
||
|
|
|
||
|
|
## 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.
|
||
|
|
|
||
|
|
## Keys
|
||
|
|
|
||
|
|
To position your ships: move the cursor to a spot, then type the first
|
||
|
|
letter of a ship (using CAPITAL letters) type to select it, then type a
|
||
|
|
direction ([hjkl] or [4862]),
|
||
|
|
indicating how the ship should be pointed.
|
||
|
|
You may also type a ship letter followed by r to position it randomly,
|
||
|
|
or type `R' to place all remaining ships randomly.

## Compiling
|
||
|
|
|
||
|
|
HiTech C has been used to compile it, but it needs a lot of free memory (TPA).
|
||
|
|
|
||
|
|
For compiling, I used the command c bs.c in CP/M.
