Previously, any font names requested by RGSS would be translated
directly to filenames by lowercasing and replacing spaces with
underscores (and finally doing some extension substitution).
To make this whole thing work smoother as well as get closer to
how font discovery is done in VX, we now scan the "Fonts/" folder
at startup and index all present font assets by their family name;
now, if an "Open Sans" font is present in "Fonts/", it will be
used regardless of filename.
Font assets with "Regular" style are preferred, but in their
absence, mkxp will make use of any other style it can find for
the respective family. This is not the exact same behavior as
VX, but it should cover 95% of use cases.
Previously, one could substitute fonts via filenames, ie. to
substitute "Arial" with "Open Sans", one would just rename
"OpenSans.ttf" to "arial.ttf" and put it in "Fonts/". With the
above change, this is no longer possible. As an alternative, one
can now explicitly specify font family substitutions via mkxp.conf;
eg. for the above case, one would add
fontSub=Arial>Open Sans
to the configuration file. Multiple such rules can be specified.
In the process, I also added the ability to provide
'Font.(default_)name' with an array of font families to search
for the first existing one instead of a plain string.
This makes the behavior closer to RMXP; however, it doesn't
work 100% the same: when a reference to the 'Font.name' array is
held and additional strings are added to it without re-assignig
the array to 'Font.name', those will be ignored.
This initial implementation emulates the way RMVX splits
the sprite into "chunks" of about 8 pixels, which it then
scrolls left/right on a vertical sine wave. It even
replicates the weird behavior when wave_amp < 0, namely
"shrinking" the src_rect horizontally.
As with bush_opacity, this effect in combination with
rotation will render differently from RMVX.
This gets rid of the "batch/flush" semantics for #set_pixel
and instead just directly uploads the pixel color to the
texture, circumventing the float conversion entirely.
Also makes a lot of code simpler in many places as calling
'flush()' is no longer required for bitmaps.
Any options that are not arrays (ie. RTP paths) specified
as command line options will override entries in mkxp.conf.
The syntax is: --<option>=<value>
Because Windows has case insensitive paths, this should
be turned on (which it is by default) for maximum
compatibility. Can be turned off as an optimization
(this will speed up startup a little depending on the
number of game assets).
nearly all of the previous required extensions are CORE in OpenGL 2.0
the remaining ones need to have fallback checks for ARB vs EXT vs APPLE
variants..
This looks like a pretty major change, but in reality,
80% of it is just renames of types and corresponding
methods.
The config parsing code has been completely replaced
with a boost::program_options based version. This
means that the config file format slightly changed
(checkout the updated README).
I still expect there to be bugs / unforseen events.
Those should be fixed in follow up commits.
Also, finally reverted back to using pkg-config to
locate and link libruby. Yay for less hacks!
An exception is made of TexPool, which will need a
bit more testing before transitioning to std containers.
Also replace 'int' with 'size_t' where it is used only
as an array index.
When using something like Valgrind that will run
mkxp 20 times slower than normal, frame skip will
make the redraw loop completely grind to a halt.
Set 'frameSkip' to false in the config to
avert this.
A previous commit prevented the MeWatch from
starting a BGM stream that was in stopped state.
However, when a new BGM is loaded while the ME
is still playing, the BGM stream will be stopped
even though we want it to start after the ME
finishes.
Also add some comments trying to explain members
of 'AudioStream' a bit better.
We didn't account for the spec dictating that
scissor test does affect FBO blit operations,
which resulted in corrupted output if more than
one viewport with an active effect (tone, color)
was created.
The reason I never caught this before must be
that the fglrx-legacy driver is actually bugged
in this aspect and ignores the scissor on blit.
The general rule I'm aiming for is to <> include
system wide / installed paths / generally everything
that's outside the git managed source tree (this means
mruby paths too!), and "" include everything else,
ie. local mkxp headers.
The only current exception are the mri headers, which
all have './' at their front as to not clash with
system wide ruby headers. I'm leaving them be for now
until I can come up with a better general solution.
With this we now link to libvorbis/ogg directly.
When this is enabled, one can theoretically also
build SDL_sound without ogg support, although I
doubt it makes much of a difference.
Adittionally, count frames instead of samples
for playback offset calculation.
We will not be using librubberband for in place
pitch shifting. RMXP "shifts" PCM based audio
by just playing it back slower/faster, which
OpenAL takes care of for us. A native midi backend
will be able to effortlessly pitch shift by
multiplying note pitches, should we ever get one.
I have been chasing this ghost for way too long.
Making this an option makes no sense. It ought to
be the default behavior, as RMXP pitch shifts PCM
based audio files the exact same way.
This reverts commit ac35d4214e.
This is a major change in the Audio module that comes with
many changes throughout the codebase and dependency list.
The main gist is that we're finally nuking the last pieces
of SFML from the project. sfml-audio brought with itself
unneeded and big dependencies (libsndfile, libvorbisenc)
while at the same time limiting the amount of audio formats
mkxp can support (eg. we now get mp3 for free, and wma/midi
can be implemented by extending SDL_sound directly).
The increased control gained by interfacing with OpenAL directly
will also allow for easy integration of a dedicated audio
stretcher (librubberband), as well as enable us to implement
looped ogg vorbis (via the 'LOOPSTART'/'LOOPLENGTH' tags),
as required by RGSS2, in the future.
The FileSystem class has had its SFML parts removed.
Aditionally, audio file extensions to be supplemented are
now automatically detected based on how SDL_sound was
built (ie. if no mp3 support was built, mkxp won't try
to look for *.mp3 files). The final used extension
can be optionally returned by 'openRead' calls so
SDL_sound and SDL2_image can immediately choose the
right decoder.
The OpenAL context is created and destroyed in main.cpp
along side the GL context.
Finally got around to nuking that ugly pile of shit that was
previously there for PhysFS file enumeration because filepath
cache generation with unencrypted game files + archive + RTP
has started taking around 6 seconds. Thank $DEITY.
We now actively track how far behind / in front of an
ideal timestep we are during each frame, and try to
catch up / delay approximate this timing.
Therefore we use more precise timers and sleep functions
(nanosleep if available). We also delay **before** the
final buffer swap so the frame displays at more consistent
points in time.
Not only should this provide a somewhat more consistent
looking map scrolling at lower frame rates, it also
guarantees that we don't fall out of sync eg. with the
Audio during longer cutscenes.
'Graphics.frameReset()' now finally has a function, in
that it resets the ideal timestep approximation, which I
beliefe was also its job in the original RMXP engine.
I'm not sure how well this will work when the frame rate
is set to the monitor refresh rate and vsync is turned on.
Very likely unnecessary frame skips will occur here and there
due to imprecise timers. In the future we should probably
check if the frame rate is equal to or higher than the
monitor rate, and disable frame skip accordingly.
These changes currently break the F2 FPS display (it shows
a value that's slightly too high).
Releasing a Tilemap atlas into the pool on every map switch
will blow out tons of smaller textures for very little gain,
as atlas textures are already pretty much impossible to
recycle anywhere but in new Tilemaps.
This reverts commit 34d4103111.
Turns out we need at least GLSL 1.50, for which we'd
have to throw our OpenGL 2.0 compatibility in the water.
Nope, not yet.
Using "SDL2/SDL_xxx.h" instead of "SDL_xxx.h" caused
the include paths provided by pkg-config to be ignored,
and headers from a standard include path to be used instead.
If consecutive scanrows in the scene list have no foreign
elements in between them, we batch them up and draw them
in one glDrawElements() call.
This should reduce the Tilemap induced draw calls on
average by at least 50 percent.
