The original implementation was pretty broken (but not used anyway),
it is now fixed and improved a bit (got rid of one inner loop).
This (at least part of the problem) was detected by PVS-Studio,
see http://www.viva64.com/en/b/0120/ Fragment 3
This happens before the SDL GL window is set up, which just
results in a warning. Another call will properly set the
gamma table after the window is initialized.
Make gammaTable a stack variable. This is sufficient, since SDL
already restores the gamma values for us on exit.
Fix silly issue from 3d692b58 (sizeof(E_EVENT_SIZEOF_VEC)).
Align entity values of events to the native pointer size, which
is noticeably faster on x86_64 and fixes another assert() in
debug builds.
Past savegames with entities in events are not compatible.
The argument size of each event is checked in debug builds
and this change was missing from the x86_64 commits.
Surprisingly this didn't trigger yet with the original game,
only with the mod 'Classic Doom 3'.
Set AL_LOWPASS_GAIN like EAX did under the hood.
Set the same filter via AL_DIRECT_FILTER on sources.
This should bring the overall sfx closer to EAX:
<kaan_> it sounds awesome
All infos provided by KittyCat from #openal.
The gain values are expressed as millibels in the .efx files
and need to be converted to normalized floating points.
Get the EAX4 EAXREVERBFLAGS_DECAYHFLIMIT from the "flags" token
and set AL_EAXREVERB_DECAY_HFLIMIT accordingly.
All infos provided by KittyCat from #openal, many thanks!
First attempt at porting the EAX reverb code to EFX.
This only works when the ALC_EXT_EFX extension is supported by
the OpenAL vendor (which is not the case for the OSX supplied
framework, use OpenAL soft instead).
The current stable version of OpenAL Soft (v1.13 as of this
writing) can barely handle this additional workload, current
master is highly recommended when using this feature.
We already link to OPENAL_LIBRARY further down.
Log some debug OpenAL info, mainly so OSX users can check they are not
using Apple's OpenAL. OpenAL Soft is recommended as it fixes many
issues.
I specify it as follows:
cmake -DOPENAL_LIBRARY=/usr/local/lib/libopenal.dylib -DOPENAL_INCLUDE_DIR=/usr/local/include -GXcode ../neo/
(because FindOpenAL.cmake prefers the /System frameworks)
