With this patch, entities can serve as a sound source whose position
updates relative to the listener. This implements the last missing
feature of my previous positional audio patch, which is moving sound sources.
Previously, all sounds were relative to the listener with the listener
centered at (0, 0, 0), and once a sound started playing, the position could
not be changed. Volume was set as an estimation of the distance to the listener.
These restrictions are now gone; OpenAL will handle the volume & panning
based on the distance.
The remaining problem is that stereo sounds are not attenuated, at all.
Lua additions:
- playSfx() takes an additional parameter now.
- entity_setStopSoundsOnDeath()
This changes all typical vector interpolation functions that get
value, time, loopType, pingPong, ease as args from the Lua state;
use unified functions for all value type occurances.
This fixes the slightly annoying problem that it was not possible to
pass a boolean true to pingPong or ease, because lua_tonumber() would
always return 0 in that case.
Also changed:
- obj_getWorldPosition() now takes optional x,y-vector
New:
- obj_getWorldPositionAndRotation() is a more efficient shortcut,
as often both position and rotation are retrieved together,
and the underlying matrix chain operation is rather expensive.
- entity_getEmitter()
- entity_getNumEmitters()
- setSceneColor2()
- getSceneColor2()
The fix as suggested by Jonas Kulla on the mailing list is also in.
There hasn't been any extensive testing, and it may not yet compile
on platforms other than win32.
- quad_setRepeatTexture()
- quad_setRepeatScale()
- quad_isRepeatTexture()
(bone, entity, ... as well)
- getOldDT() - return unmodified dt
- getDT() - as passed to update(), for complicated edge cases
where dt is unavailable but required.
This commit is mainly intended to ease packaging for linux.
Unless environment variable AQUARIA_DATA_PATH is set, there are two
directories which are checked by the game:
If AQUARIA_DEFAULT_DATA_DIR is defined, it will chdir there for main
operation. If it's not defined, it chdirs into the directory where
the executable is located.
Then, if AQUARIA_EXTRA_DATA_DIR is defined, it will mount this directory
and all contents into the working path, so that the files present there
will override those from the working directory when accessed by the game.
Setting the environment variable AQUARIA_DATA_PATH will disable this
behavior altogether and use *only* AQUARIA_DATA_PATH as working dir.
This has the side effect that elements on the dark layer will now properly
wiggle when affected by water ripples.
Before this patch, the dark layer was always drawn above the postprocessed
screen content, unaffected.
This allows attaching multiple shader programs, processing the entire
screen as texture. Chaining shaders works, each shader will use
the output of the previous shader as input.
This repairs pixel/vertex shader code that was seemingly
experimented with during testing, but it was never used and no
shaders ever made it to the data files.
GL_CULL_FACE is effectively always disabled, except for quad strip
rendering, and keeping GL_CULL_FACE disabled there does not seem
to cause any visual artifacts.
Instead, it enhances skeletal animation possibilities
(e.g. flipping bone strips over without it disappearing)
This commit introduces a second pause mode:
Full game pause (as in menu), and world pause (as in spirit form).
All related checks are no longer done against WT_* constants,
but against the new world pause which is functionally equivalent,
but more flexible. Continuity::worldType is now only used to toggle
world pause correctly, and to apply some related graphical effects.
The world pause can also be controlled via script without actually
switching forms.
Added Lua functions:
+ node_setSpiritFreeze()
+ quad_setPauseLevel()
+ isWorldPaused()
+ setWorldPaused()
The first one caused the music to stop randomly on scene changes,
reproducible by changing maps with different music while holding 'G'
button to speed up time.
For some reason this caused the music to stop playing during the crossfade.
Wasn't able to find the root cause, so I added a little hack to kick the
music back on track if it stops unexpectedly.
The second one was a simple string case issue; mostly noticable because of
map background sounds not playing in loop mode.
(this is possibly a regression from an earlier patch, not sure)
