WIN_DESKTOP means that this can currently only be set for the top-level
window in a .gui (all its subwindows/widgets will be scaled implicitly)
There are two ways to make a GUI use this:
1. in the .gui add a window variable "scaleto43 1", like
windowDef Desktop {
rect 0 ,0 ,640 ,480
nocursor 1
float talk 0
scaleto43 1
// .. etc rest of windowDef
2. When creating the GUI from C++ code, you can afterwards make the
UserInterface scale to 4:3 like this:
idUserInterface* ui = Whatever(); // create it
ui->SetStateBool("scaleto43", true);
ui->StateChanged(gameLocal.time);
Both lines are important!
As you can see in my changes to Player.cpp, my primary usecase for this
is the cursor/crosshair GUI.
So stuff doesn't look so distorted in widescreen resolutions.
Implies that there are black bars on the left/right then..
Can be disabled with "r_scaleMenusTo43 0"
Does *not* affect the HUD (incl. crosshair) - scaling it automagically
would be very hard (or impossible), because it doesn't only render
the crosshair, healthpoints etc, but also fullscreen effects like the
screen turning red when the player is hit - and fullscreen effects
would look very shitty if they didn't cover the whole screen but had
"empty" bars on left/right.
(Mostly) fixes#188 and #189
Mods that have their own video settings menu can tell dhewm3 to replace
the "choices" and "values" entries in their choiceDef with the
resolutions supported by dhewm3 (and corresponding modes).
So if we add new video modes to dhewm3, they'll automatically appear in
the menu without changing the .gui
To enable this, the mod authors only need to add a "injectResolutions 1"
entry to their resolution choiceDef. By default, the first entry will
be "r_custom*" for r_mode -1, which means "custom resolution, use
r_customWidth and r_customHeight".
If that entry shoud be disabled for the mod, just add another entry:
"injectCustomResolutionMode 0"
This is an ugly hack that allows both exporting additional functions
(incl. methods via static function + void* userArg) to Game DLLs
and setting callback functions from the Game DLL that the Engine will
call, without breaking the Game API (again after this change).
This is mostly meant for replacing ugly hacks with SourceHook and
similar and mods (yes, this is still an ugly hack, but less ugly).
See the huge comment in Common.h for more information.
Right now the only thing implemented is a Callback for when images
are reloaded (via reloadImages or vid_restart) - Ruiner needs that.
Also increased GAME_API_VERSION to 9, because this breaks the A[PB]I
(hopefully after the next release it won't be broken in the foreseeable
future)
if --help or -h or -help or -? or /? is passed as commandline argument,
the help is printed (to stdout) and then the game quits.
The help shows some helpful commandline arguments, including how to
tell the engine where to find the game data, how to set the resolution
and more
If an OpenAL source runs out of samples it transisions into state
AL_STOPPED. That happens if we're entering the menu (which switches
to another soundworld) and when saving the game (because the game
blocks for some milliseconds). Work around this by adding a new
field 'stopped' to the channel state and use that to determine if
a sound was stopped. And not AL_STOPPED like before.
In the last few weeks I've played again through the game and kept an eye
on small oddities. And there're a lot of them. For example some GUIs and
videos getting stuck after the first frame (issue #192) or being unable
to protect the guy with the lamp in Alpha Labs 3. Some digging proved
that most - if not all - of these problems are caused by the compilers
optimization level. When build with -O2 both g++ 8.1 and clang 6.0.0 are
producing working code. g++ 8.1 with -O3 has some small, hard to notice
oddities, clang 6.0.0 with -O3 shows a lot of them. Since there's not
measurable difference between -O3 and -O2 just go down to the later:

so even with many loud sounds the overall volume isn't reduced by
OpenAL - apparently OpenAL scales down all sounds temporarily if the
mixed result would be too loud or sth like that.
Just sending all sounds to OpenAL with a lower volume prevents that from
happening (just set your system speaker volume a bit higher if needed).
This problem was especially noticable when shooting at metal walls with
the shotgun (each pellet produces an impact sound so it gets kinda loud)
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)
On FreeBSD, the game used to crash when loading the last level of RoE
(d3xp), while loading models/david/hell_h7.ma.
The problem could be reproduced on Linux whith #define USE_LIBC_MALLOC 1
and clang's AddressSanitizer.
Turns out that this file specifies a vertex transform for a non-existent
vertex (index 31, while we only have 0-30) and thus the bounds of
pMesh->vertexes[] are violated.
I added a check to ensure the index is within the bounds and a Warning
if it isn't.
It should work now. If however it turns out that more files have this
problem, maybe .ma is parsed incorrectly and we need a differently fix.
(Should) fix#138
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.
__builtin_trap() causes an illegal instruction and thus the process
can't resume afterwards.
raise(SIGTRAP) only breaks into the debugger and thus allows to
"ignore" the assertion while debugging.
