Release notes on the source code:
A message from Dave Clark:
> I have already begun to take emails requesting assistance with the
> compilation of the Sopwith code place on sopwith.org. Although I would
> like to have the time to help everyone with its recompilation, I simply
> don't have the time. If I can, I would like to ask that emails directed to
> me concerning the code be restricted to the higher level "Why did you do it
> this way", rather than the more "nuts and bolts" type questions (i.e. The
> source won't compile under Frisbot C++, what's wrong?). If you really hit
> a roadblock with a particular piece of the code, I will help if I can, but
> please be very specific as to what the problem is (specific lines of codes,
> error messages, etc). If anyone else wants to become a Sopwith porting
> expert, and is able to handle the support calls involved, my best wishes to
> that person.
>
> The code is written to compile under Microsoft C V6.0 (for DOS) and
> Microsoft Assembler V5.1 (for DOS). I'm truly sorry, but I do not have the
> time to assist in porting it to any other compilers.
>
> I would ask that all questions concerning the code be sent to the Sopwith
> development eGroup, rather than to me directly. In that way, the greater
> number of people can contribute to and learn from the answers.
>
> I hope I'm not coming across too heavy here. I thoroughly encourage what
> folks are doing with Sopwith. Time permitting, I will attempt to answer
> every eMail regarding Sopwith. Please be patient, as Sopwith has become an
> unexpected addition to an already busy schedule.
>
> Thanks for you consideration
> Dave Clark
The Sopwith developers mailing list can be joined by going to
http://www.egroups.com/subscribe/sopwith
and following the instructions there.
The files in the source code archive are as follows:
Dave Clark stuff:
General stuff:
LICENSE.TXT - The Sopwith license agreement
NOTES.TXT - This file
SW.LNK - Linker response file
SW.MAK - Makefile
C Stuff:
SW.H - Main Sopwith header file. Included by all the C files.
Includes STD.H, SYSINT.H, SWDEVE.H and SWMACH.H. Has lots of
useful macros for constants and enumerations, as well as
definitions of the various structs.
STD.H - Header defining some handy macros and prototypes for some of
the functions in BMBLIB.C
SWDEVE.H - Defines the "DEVELOPE" macro.
SWMACH.H - Defines either the "IBMPC" macro or the "ATARI" macro
depending on the machine being compiled for.
SYSINT.H - Defines register structures used by sysint and sysint21 and
interrupts.
SWMISC.C - Miscellaneous support functions ("puts" function)
_INTC.C - Functions to handle Sopwith's interrupt vector table
BMBLIB.C - BMB library routines (command line processing, system
interrupts, hardware I/O and memory copying).
SWASYNIO.C - Asynchronous (serial port) communications
SWAUTO.C - The autopilot (computer player and automatic homing device)
SWCOLLSN.C - Collision detection routines
SWDISP.C - Display players and objects
SWEND.C - End of game cleanup and statistics
SWGAMES.C - Defines the positions, types and orientations of the runways
and buildings in the "world".
SWGROUND.C - Defines the array of altitudes which makes up the landscape
SWGRPHA.C - Low-level graphics routines
SWINIT.C - Initialization routines, command line and menus
SWMAIN.C - The main game loop
SWMOVE.C - Update objects
SWMULTIO.C - Imaginet multiplayer communications
SWNETIO.C - Modern networking replacement for SWMULTIO.C (or at least, it
will be...)
SWOBJECT.C - Routines for manipulating the object list
SWSOUND.C - Sound routines
SWTITLE.C - The title screen
SWPLANES.C - Graphics data for planes
SWSYMBOL.C - Other graphics data
Assembler stuff:
SEGMENTS.H - Assembler macro defining relative position of function call
arguments on stack
SW.HA - Assembler include for various useful constants
_INTA.ASM - Interrupt service routines, routines to get and set interrupt
vectors
_INTS.ASM - Functions to turn interrupts on and off
SWCOMM.ASM - Low level serial communications
SWGRPH.ASM - Low level graphics routines (duplication of some of the stuff
in SWGRPHA.C)
SWHIST.ASM - Dummy history processing
_DKIO.ASM - Low level disk I/O for Imaginet
SWUTIL.ASM - Keyboard, joystick, timing, sound, text output and object
movement routines
Andrew Jenner stuff:
General stuff:
MAKEFILE - Make file. Works with Borland make. Doesn't work with GNU
make for reasons which escape me (please tell me if you
know). Don't know about other flavours of make.
RESPONSE.RSP - Linker command line (response) file to link Sopwith. Works
with Borland TLINK 2.0.
RESPONS2.RSP - Linker command line (response) file to link Sopwith 2. Works
with Borland TLINK 2.0.
SOPWITH.PRJ - Turbo C 2.01 project file for Sopwith.
SOPWITH2.PRJ - Turbo C 2.01 project file for Sopwith 2.
DLCVSAMJ.TXT - File giving correspondances between identifiers in Dave
Clark's code and Andrew Jenner's. Work in progress.
Code:
SOPWITH.C - Sopwith.
SOPWITH2.C - Sopwith 2.
DEF.H - Generic header file
SOPASM.ASM - Assembler support routines, common to Sopwith and Sopwith 2.
Works with A86.
SOPASM.H - Header file declaring the functions in SOPASM.ASM.
GROUND.C - Landscape height field, common to Sopwith and Sopwith 2.
SPRITES.C - Graphics data, common to Sopwith and Sopwith 2.
