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.
|
||
|
|
|
||
|
|
See the ``*.txt`` files for more information.
|
||
|
|
|
||
|
|
## 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.
