Otherwise especially looped sounds continue playing while the menu
is open, especially noticeable when opening the menu while firing
the chaingun (the whirring sound continues playing).
the problem was that the sources were still associated to it, because
they get deleted after the listenerSlot: the sources get freed in
idSoundSystemLocal::Shutdown() which is called by
idCommonLocal::ShutdownGame() in line 3217,
while the listenerSlot is deleted via idSessionLocal::Shutdown()
-> delete sw/rw -> idSoundWorldLocal::~idSoundWorldLocal()
-> idSoundWorldLocal::Shutdown() - and idSessionLocal::Shutdown() is
called in idCommonLocal::ShutdownGame() line 3211, before the other.
I'm not gonna mess with the order of deleting things in ShutdownGame(),
but it's sufficient to unassociate the effect slot from the source
when destroying the emitters in idSoundWorldLocal::Shutdown(),
by adding a call for that to idSoundChannel::ALStop() - and destroying
the emitters before deleting listenerSlot.
Before this fix, with ALSOFT_LOGLEVEL=3 you got the following warning:
(WW) Error generated on context 0x5578fce2a280, code 0xa004,
"Deleting in-use effect slot 1"
Thanks for openal-soft's KittyCat for pointing this out!
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.
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.
variable set but not used
Removes some CollisionModel code under _DEBUG which was probably a
leftover, since it was completely useless (its done later anyways).
