I think the reason this was originally done was some
issue with ruby's GC where it would wrongfully sweep
the script array variable on the C stack.
This change should speed up startup a little.
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.
