- s_scaleDownAndClamp CVar so the clamping and scaling down of all
sounds (that is done to prevent clipping) can be disabled
(enabled by default)
- s_alOutputLimiter CVar to allow configuring ALC_SOFT_output_limiter
which (if enabled) reduces the overall volume if it gets too loud,
to avoid clipping (defaults to -1 = "let OpenAL decide")
- s_alHRTF to allow enabling or disabling HRTF, requires ALC_SOFT_HRTF
(defaults to -1 = "let OpenAL decide")
Those CVars can be changed at runtime and are applied immediately
(in case of s_alHRTF and s_alOutputLimiter by resetting the OpenAL
device, just like we do when a disconnect is detected)
In the main menu the ImGui/SDL/System cursor was only drawn when it was
over an ImGui window, so only the Doom3 cursor is shown when outside
of ImGui windows.
The only problem with this is that the Doom3 cursor is only shown in
the parst of the window actually covered by the main menu, not the black
bars that are drawn on the left/right for widescreen-resolutions when
scaling the menu to 4:3 is enabled (which it is by default).
So now the ImGui cursor is also drawn when the cursor is on those
black bars (if any).
Also tweaked the windowtitle background colors a bit.
* Binding menu makes sure that the AllBindingsMenu always gets focus
when opened
* Give binding-related popups slightly rounder edges
* Move Game Options tab behind Video and Audio Options
* Make warning overlays a bit less translucent
Pause the game (with g_stopTime) when the settings menu is opened
while ingame, unpause it when it's closed.
If the menu is open while ingame and an ImGui window has focus,
the mouse cursor is shown. If the player clicks outside an ImGui window,
it gets unfocused and the cursor is hidden and the player can look
around. Pressing F10 (or whatever key is bound to "dhewm3Settings")
will give focus back to an open ImGui window, pressing it again then
will close the settings window, pressing it once again afterwards will
open the settings window again.
handleMouseGrab() (in sys/events.cpp) now checks if sys_imgui thinks
that a cursor should be shown (via D3::ImGuiHooks::ShouldShowCursor())
and if so, shows it and ungrabs the mouse. This, together with
D3::ImGuiHooks::NewFrame() checking ShouldShowCursor() to (unset)
ImGuiConfigFlags_NoMouseCursorChange, should prevent flickering cursor
problems that sometimes occurred when ImGui's SDL2 backend and dhewm3
disagreed on whether the cursor should be visible.
Also fix MSVC build: For some reason Microsoft's sad excuse of a compiler
only sets __cplusplus to a value from this millenium if the
/Zc:__cplusplus compiler option is set, but that's only supported from
VS2017 15.7 on. The alternative is to use _MSVC_LANG, which always holds
the version that __cplusplus *should* have...
I actually did this before the prototyping of a keybindings menu
in the imgui example code, so the prototype is actually based on this.
I'll merge the code from the prototype back once it's done.
idStr::(V)Format() is a static (v)printf-like function that returns
and idStr. Can be used like a better va(), or for
idStr mystr = idStr::Format( "number of items: %d", myarr.Num() );
turns out that __builtin_alloca_with_align() might releases the
allocated memory at the end of the block it was allocated in, instead
of the end of the function (which is the behavior of regular alloca()
and __builtin_alloca()): "The lifetime of the allocated object ends at
the end of the block in which the function was called. The allocated
storage is released no later than just before the calling function
returns to its caller, but may be released at the end of the block in
which the function was called."

Clang also supports __builtin_alloca_with_align(), but always releases
the memory at the end of the function.
And it seems that newer GCC versions also tend to release it at the
end of the function, but GCC 4.7.2 (that I use for the official Linux
release binaries) didn't, and that caused weird graphical glitches.
But as I don't want to rely on newer GCC versions behaving like this
(and the documentation explicitly says that it *may* be released at
the end of the block, but will definitely be released at the end of
the function), I removed all usage of __builtin_alloca_with_align().
(Side-Note: GCC only started documenting the behavior of
__builtin_alloca and __builtin_alloca_with_align at all with GCC 6.1.0)
added a simple helper print method to know what key/button is being pressed,
controlled via a bool cvar "in_namePressed" 1 or 0.
I tested it and it works with keyboard, mouse and gamepad.
it could happen that UIs are added to the internal list twice,
and also that the last UI wasn't removed from the list when a new one
was focused fast enough.
That should work better now, I hope I didn't break anything..
