|
||||
This file contains information on the implementation of the direct play
|
||||
and direct play lobby features. There's lots to do and I'm not exactly
|
||||
implementing it overnight! Please lend a hand.
|
||||
|
||||
Most methods and APIs are but stubs at this point. Examine the code
|
||||
to see what has been implemented. Use -debugmsg +dplay to get a
|
||||
reasonably thourough description of what's going on.
|
||||
|
||||
Associated DirectX user header files are include/dplay.h, include/dplobby.h.
|
||||
|
||||
Implementation of the DPLAY and DPLAYX dlls are both in the dlls/dplayx
|
||||
directory. Here's a brief description of the function of each of the files in that
|
||||
directory:
|
||||
|
||||
dplay.c: Implementation of all the direct play object interfaces.
|
||||
|
||||
dplobby.c: Implementation of all the direct play lobby interfaces.
|
||||
|
||||
dpclassfactory.c: Implementation of the COM class factory which can create either
|
||||
direct play lobby or direct play lobby interfaces.
|
||||
|
||||
dpinit.h: Header file so that dpclassfactory.c can access dplay and dplobby query
|
||||
functions. Shouldn't be included by anything else.
|
||||
|
||||
dplayx_global.h,
|
||||
dplayx_global.c: Implementation of all things which are associated with dplay on
|
||||
the computer - ie shared resources and such. Methods in this
|
||||
compilation unit should not call anything out side this unit
|
||||
excepting base windows services and an interface to start the
|
||||
messaging thread.
|
||||
|
||||
name_server.h,
|
||||
name_server.c: Implementation of all things which are associated with the name
|
||||
server functionality
|
||||
|
||||
dplayx_main.c: LibMain executed for loading and unloading the dll. This will make
|
||||
the call to dplayx_global.c to request initialization and destruction
|
||||
of any global data.
|
||||
|
||||
dplayx_queue.h: Linked list implementation for dplay/dplobby. Based off of the BSD
|
||||
version found in <sys/queue.h>
|
||||
|
||||
dplayx_messages.h,
|
||||
dplayx_messages.c: Messaging interface required for both DirectPlay and
|
||||
DirectPlayLobby.
|
||||
|
||||
dplaysp.c,
|
||||
dplaysp.h: COM interface between DPLAYX and the service provider dlls. dplaysp.h is
|
||||
something that should be included into any service provider. Basically
|
||||
the COM interface is partially documented but is generally lacking in the
|
||||
finer points.
|
||||
|
||||
Presently the architectural relationship between this files is a little shakey, but
|
||||
isn't so sufficiently bad that it needs fixing yet.
|
||||
|
||||
I think I can safely say that any application which requires direct play
|
||||
or direct play lobby will not work at this point. Priority will be to get
|
||||
examples from the sdk running. Once they're at least partially working, I can
|
||||
get down to trying to get some of the games working.
|
||||
|
||||
However, now that address separation is a reality, all binary samples provided
|
||||
in the sdk can be used. I have had success spawning processes and one
|
||||
directx7 example will allow creation of an app and allow another to join it.
|
||||
Unfortunately, there isn't much for it to be able to do give the state of
|
||||
inter directlobby or directplay messaging.
|
||||
|
||||
Messages which work:
|
||||
|
||||
For session enumeration: DPMSGCMD_ENUMSESSIONSREPLY & DPMSGCMD_ENUMSESSIONSREQUEST
|
||||
have most fields understood, but not all. Everything _seems_
|
||||
to work.
|
||||
|
||||
For playerid requesting: DPMSGCMD_REQUESTNEWPLAYERID & DPMSGCMD_NEWPLAYERIDREPLY
|
||||
barely work. This needs to be completed for sessions to be
|
||||
able to actually start.
|
||||
|
||||
A small issue will be the fact that DirectX 6.1(ie. DirectPlay4) introduces a layer of functionality
|
||||
inside the DP objects which provide guaranteed protocol delivery. This is
|
||||
even if the native protocol, IPX or modem for instance, doesn't guarantee it. I'm going to leave
|
||||
this kind of implementation to as close to the end as possible. However, I
|
||||
will implement an abstraction layer, where possible, for this functionality.
|
||||
It will do nothing to start, but will require only the implementation of the
|
||||
guaranteness to give final implementation.
|
||||
|
||||
|
||||
TODO:
|
||||
- (done) Header files for DP4 and DPL3
|
||||
- (done) Add stub functions for all DP4 and DPL3 interfaces
|
||||
- (done) Correct naming of the parameters for DP3 and DPL2
|
||||
- (done) Separate out DP and DPL into multiple .c files
|
||||
- (done) Allow CoCreateInstance to create the new interfaces
|
||||
- (started)Implement mutual exclusion on object data for existing functions
|
||||
- (done) Create and move to correct dll directories (dplay and dplayx)
|
||||
- (done) Implement dplay in terms of dplayx
|
||||
- (done) Need a better internal implementation for the objects which scales and
|
||||
preferably doesn't involve casting structures. Solution is a crude ctor/dtor
|
||||
which can actually trap some runtime errors.
|
||||
- (done) More generic initialization and destruction helper methods based off
|
||||
the chosen internal implementation. Solution is a crude ctor/dtor.
|
||||
- Use only windows routines where an equivalent is available
|
||||
- (done) Fix wine dplay.h and dplobby.h header files to allow apps to create the ansi versions
|
||||
- (started) Port some WineLib test programs using sdk programs (both C and C++ progs)
|
||||
- (done) Implement a lib main for the dplayx dll (required for RunApplication, etc.)
|
||||
- (done)Figure out how to share the global memory correctly
|
||||
- Ensure that all dll stubs are present and the ordinals are correct
|
||||
- (started) Implementation of functionality
|
||||
- Addition of DirectX 7.0 functionality for direct play (try to catch that moving train)
|
||||
- bug fixes ;)
|
||||
- Implement some WineLib test programs using sdk programs as a skeleton
|
||||
- (done) Change all RegEnumKey calls to RegEnumKeyEx.
|
||||
- Change RegEnumKeyEx enumeration pattern to allow error handling and to
|
||||
share registry implementation (or at least simplify).
|
||||
- Add in appropriate RegCloseKey calls for all the opening we're doing...
|
||||
- Fix all the buffer sizes for registry calls. They're off by one - but in a safe direction.
|
||||
- (done) Find out how to call the service provider dlls - they don't have a published interface!
|
||||
- Fix race condition on interface destruction
|
||||
- Handles need to be correctly reference counted
|
||||
- Need to check if we need to deallocate any list objects when destroying
|
||||
dplay interface
|
||||
- RunApplication process spawning needs to have correct syncronization.
|
||||
- Need to get inter lobby messages working.
|
||||
- Decypher dplay messages between applications and implement...
|
||||
- Need to implement lobby session spawning.
|
||||
|
||||
ENHANCEMENTS:
|
||||
- Improve footprint and realtime blocking by setting up a separate data share
|
||||
between lobby application and client since there can be multiple apps per
|
||||
client. Also get rid of offset dependency by making data offset independent
|
||||
somehow.
|
||||
- Handle everything in UNICODE (as server does) and do conversions for ANSI
|
||||
interfaces. Should cut down on dplayx code base and maintanability (marginally)
|
||||
and could be used to improve efficiency of dialog with the server (it wouldn't
|
||||
have to do ANSI<->UNICODE transformations).
|
||||
|
||||
|
||||
|
||||
Programs to make work:
|
||||
- lserver.exe (from sdk)
|
||||
- override.exe (from sdk)
|
||||
- dpchat.exe (from sdk)
|
||||
- duel.exe (from sdk)
|
||||
- dplaunch.exe (from sdk)
|
||||
|
||||
Next API to implement on a per SDK program basis:
|
||||
override.exe
|
||||
- (calls dpserial so basic problems with that remain)
|
||||
- after that ?
|
||||
|
||||
dplaunch.exe
|
||||
- I think that everything is basically working. The launched app may not
|
||||
work on the other hand.
|
||||
|
||||
lserver.exe
|
||||
- Missing messaging portion. Everything else works.
|
||||
|
||||
bellhop.exe
|
||||
- Need to implement lobby server support.
|
||||
- ?
|
||||
|
||||
dpslots.exe
|
||||
- Works as host except for message stuff
|
||||
- Missing correct handling of receipt of playerid
|
||||
|
||||
Other TODO:
|
||||
|
||||
- look at problem with parsing the resource file for dplaunch. wrc problem?
|
||||
- I should be getting the dialog box to come up for dpchat when something is selected
|
||||
