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.
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.
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.
This replaces the previously directly bound #clone
methods, which weren't really the "the Ruby way".
Rubys default Object#clone will call into our #init_copy
methods instead.
Partly incorporates pull request #3 by /cremno.
Previously, wrapped instances of mkxp core classes were
stored as RData ivars inside the actual object. This turned
out to be pointless as RData objects themselves are perfectly
valid objects that can carry ivars and have parent classes.
Therefore, the RData objects are now exposed directly to
the user scripts, effectively halving the amount of object
allocations.
We override 'Marshal::load()' via alias and call it with
a custom auxiliary proc in the alias which sets the encoding
of all demarshalled strings to UTF-8. The case where a user
himself provided a proc to 'load()' is not implemented.
This is definitely a better solution than patching the ruby
source tree. Thanks to github.com/cremno for hints and help!
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.
What can I say. I made a pact with the devil, and paid dearly.
Almost a whole day's worth of debugging, actually. Not again.
If this turns out to be slow we can always optimize the critical
parts (with no variable param count) later, or completely remove it.
