I updated sdl2-config.cmake in dhewm3-libs so building on Windows with
them works again, however that required also a little change in
dhewm3's CMakeLists.txt
I also still had some uncommited changes for that fullscreen workaround
that I'm committing now.
.. that doesn't switch the display resolution, but creates a borderless
fullscreen window at current desktop resolution.
SDL2-only (SDL_WINDOW_FULLSCREEN_DESKTOP).
Doing this with an additional CVar instead of r_fullscreen 2 or similar
has the advantage that it works properly with Alt-Enter
SDL has a bug (at least on Windows) where SDL_CreateWindow() with
SDL_WINDOW_FULLSCREEN doesn't use the configured resolution (if it's
higher than the current desktop resolution).
Try to work around that - based on Yamagi Quake II code.
Also, if GLimp_Init() fails, the "safe mode" fallback is now in
windowed mode instead of fullscreen mode.
the game was frozen (the main menu and console worked though) when
switching from the Radiant to the engine (with F2 or that button).
Turned out common->ActivateTool( false ) must be called if the game window
has forcus, so idSessionLocal::Frame() doesn't return early (and thus not
run the game code).
Furthermore, there was no sound when switching from Radiant to the game,
because the SoundWorld was set to sth editor-specific. Fixed that as well.
OpenAL devices can disconnect, and with some luck they're back after
a few seconds. This especially seems to happen with Intels Windows GPU
driver and display-audio when switching the resolution or enabling
fullscreen, see #209
Now a disconnect is detected and we try to reset the device for 20
seconds, hoping it comes back. This needs at least openal-soft 1.17.0
to build and 1.20.0 or newer to actually work.
Also added missing stub functions in openal_stub.cpp (used by dedicated
server so it doesn't have to link libopenal)
On Windows, ID_INLINE does __forceinline, which is bad if the function
calls alloca() and is called in a loop..
So use just __inline there so the compiler can choose not to inline
(if called in a loop).
This didn't cause actual stack overflows as far as I know, but it could
(and MSVC warns about it).
the tables contain character constants like ('ä') that are supposed to
be interpreted as ISO8859-1 or WINDOWS-1252 or sth, but that doesn't
seem to work with MinGW (anymore) - seems like it assumes UTF-8 by
default, and for some reason -finput-charset=ISO8859-1 doesn't help
either, it complains about multichar character constants then..
Anyway, now the table entries are represented as the corresponding
integer constants which seems to work as intended.
Fixes#238
Editor also seems to start, didn't test much further.
Only tested 32bit Windows, I fear the editor code isn't 64bit clean..
I hope I haven't broken anything elsewhere..
causes trouble on macOS, and we shouldn't interact with X11 directly
anyway, because SDL does it for us.
OpenBSD apparently needed it (at least it was added for OpenBSD
support), but the only place I can imagine it being needed is the
superfluous #include <SDL_syswm.h> in neo/sys/glimp.cpp - which I now
removed. In case it's needed after all please tell me, then I'll add it
again - but guarded by if(os STREQUALS "OpenBSD") or however one checks
for OpenBSD in CMake.
handling SIGTTIN/OU allows running Doom3 in the background (or even
sending it to the background with Ctrl-Z + bg) by disabling TTY input
(before it would get stuck when run in background without +set in_tty 0,
see #215)
While at it, I also added signal handlers for some common crash signals
(SIGILL, SIGABRT, SIGFPE, SIGSEGV) to print a backtrace before exiting
the game (partly based on Yamagi Quake II code).
Sometimes memory was allocated with new[] but freed with delete instead
of delete[], which is wrong.
And there were some small memory leaks, too.
Furtunately clang's AddressSanitizer detected all that so I could easily
fix it.
(There seem to be some more small memory leaks which are harder to fix,
though)
as we do int buttonIndex = ev.button.button - SDL_BUTTON_LEFT;
it's only consistent to do if(ev.button.button < SDL_BUTTON_LEFT + 8)
it doesn't really make any difference as long as SDL_BUTTON_LEFT is 1,
but this way it's safe for SDL3 or whatever future version might break
the ABI.
The first row of AZERTY-Keyboards (used in France and Belgium) doesn't
have numbers as keys but ², &, é, ", ', (, -, è, _, ç, à, ), =
(with small differences between France and Belgium).
For some of those keys we don't have keycodes - and neither does SDL2.
See also https://bugzilla.libsdl.org/show_bug.cgi?id=3188
As a workaround, just map those keys to 1, 2, ..., 9, 0 anyway, as those
are keys Quake2 already knows (and those chars are printed on the keys
too, for typing they're reachable via shift).
This workaround only works for SDL2, as SDL1.2 doesn't have Scancodes
which we need to identify the keys.
This should obsolete one part of pull request #135
It's an SDL_TEXTEDITING event which we seem to get on Windows whenever
the Window gains focus (or is created). I think it can be safely
ignored, so that's what I do.
I also changed how those warnings are printed - as a hex number now,
because they're defined as hex numbers in the SDL source and it's easier
to find out what kind of event it is this way.
If res_none (event with .evType == EV_NONE) is returned,
idEventLoop::RunEventLoop() will assume there are no more events this
frame => pending events will be delayed til next frame (or later if
again res_none is returned in the meantime).
So res_none shouldn't be returned just because there was an SDL event
we didn't care about or we did care about but don't generate a doom3
event for (but toggle fullscreen or something).
Instead we should just fetch and handle the next SDL event.
Before checking there I look for gamedata next to the executable, but
the check was broken: I got the directory the executable is in and
checked if it exists.. well.. of course it does, but that doesn't mean
there's game data in it..
So now I check if that directory actually has a "base/" subdirectory
(or whatever is #defined in BASE_GAMEDIR) and if that fails
/usr/local/games/doom3/ is tried instead.
Thanks chungy for pointing the bug out in #97 !
the problem was that the CVar was initialized from the commandline
*after* Posix_InitConsoleInput() is called, so it was too late.
common->StartupVariable() seems to be the right way to initialize a
CVar early.
Commit 9e158470 set the SDL OpenGL attribut SDL_GL_ALPHA_SIZE to 0 since
the alpha channel is used by Wayland. But for X11 the GLX 1.4 specification
clearly states: "If the requested number of bits in attrib_list for a
particular color component is 0 or GLX_DONT_CARE, then the number of
bits for that component is not considered." So if SDL_GL_ALPHA_SIZE is
0 a framebuffer without an alpha channel is created. This is no problem
on the default GLX module due to a non standard implementation but
manifests with Nvidias GLX module. The consequence are render mistakes
like in game display showing static or the flashlight looking weird.
* the OpenAL function definitions mustn't include __declspec(dllimport)
=> fixed by pretending to compile OpenAL statically
* glimp.cpp shouldn't be used in dedicated-only mode (as it was already
the case on Linux and OSX)
=> No special handling for ID_DEDICATED needed in glimp.cpp, as it's not
used anyway
* add APIENTRY to every gl function in stub_gl.cpp for compatibility
with windows headers and MSVC
* remove GL/gl.h #include from win_local.h as it's not needed
* in qgl.h, when building dedicated server for windows, redefine WINGDIAPI
to nothing for SDL_opengl.h #include to get rid off __declspec(dllimport)
by using #pragma push_macro and pop_macro, because our stub is no dll.
Fixes https://github.com/dhewm/dhewm3/issues/39
Some functions were duplicated, the only difference was a const in one
parameter. The definitions in the header were with const, so I kept
those versions.
Also, the functions in the header are pure C, so add extern "C",
this fixes issues with MSVC and the formerly duplicated functions.
There used to be a bug (discussed in #40), that ALT was still set after
using ALT-Tab. Thus when next pressing enter fullscreen was toggled.
This should now be fixed by unsetting the modifiers when focus is
regained (SDL_ACTIVEEVENT or SDL_WINDOWEVENT_FOCUS_GAINED).
Since we don't have our own signal handler anymore, those two
init functions can be merged into the existing Sys_Init(), which
is already called by common->Init().
warning: variable ‘err’ set but not used [-Wunused-but-set-variable]
warning: unused variable ‘len’ [-Wunused-variable]
warning: format ‘%d’ expects argument of type ‘int’, but argument 3

This was only implemented with MSVC style asm.
Comments suggest that it was used to help catch invalid FOV calculations,
which were probably only happening with ancient compiler bugs.
