Add a mechanism for libraries to resolve incompatibilities between
library versions before linking.
This is currently used for ChipmunkSpriteEngine and GoatGUIEngine,
where early versions used integer IDs when loading CGs (later versions
use strings).
There are now two types of asset management:
1. ID-indexed assets, where IDs are not necessarily sequential
2. name-indexed assets
Name-indexed assets can have additional archives added at run-time. This
is to support the CGManager.LoadArchive function used in Rance Quest
Magnum.
Name-indexed assets always use .afa archives. ID-indexed assets mostly
use .ald archives, except for Daiteikoku and Shaman's Sanctuary.
asset_get_by_name is now case insensitive and ignores the file
extension.
asset_exists and asset_get now take 1-indexed IDs.
Custom CG indexing code for Shaman's Sanctuary is now removed and
replaced with a proper implementation of afa v1 archives in libsys4.
ReignEngine is the 3D rendering engine used in Toushin Toshi III, and is
the predecessor of the 3D engines for Rance Quest, Rance 9, Evenicle,
etc.
This implements minimal functionality to be able to draw the first 3D
dungeon scene. Many important parts such as motion and lighting are not
implemented yet.
This introduces draw_plugin struct that can be attached to a sprite.
The update() function of attached plugin is called every frame by
sact_Update(). This corresponds to the DrawPlugin mechanism of
System4/SACT2.
This is currently used only from DrawDungeon. The 3D engine for Toushin
Toshi 3 etc. will also use this.
Fix issue where outlines would get cropped when crossing the glyph
texture boundary.
This is accomplished by adding 4 border pixels to each glyph texture.
SDL_ttf isn't really designed to be used with OpenGL. It caches glyph
bitmaps in memory, whereas we want to cache glyph textures on the GPU.
By using FreeType directly we avoid creating and destroying a new
texture every time a glyph is rendered.
Additionally, all glyph textures (including fnl-derived glyphs) now use
the GL_RED internal format instead of GL_RGBA.
Part of StoatSpriteEngine and KiwiSoundEngine.
This fixes an issue with per-channel volume settings not working
correctly in Haruurare (and presumably other games).
Only unscaled glyph bitmaps are now cached in regular memory. Scaled
glyphs are stored as textures on the GPU. Only the alpha channel on
glyph textures is used, with the color being provided as an input to the
shader.
Outline and bold rendering is improved by using a simple dilate shader.
This looks okay but could be improved (the result is a bit blurry
still).
This improves the look and (especially) the performance of text
rendering in the MangaGamer version of Sengoku Rance.
There are still some bugs/unimplemented features, but the game should be
more or less bearable to play in this state.
The game now basically runs, but with very bad performance and lots of
aliasing on text.
Need to implement anti-aliasing and caching of rendered glyphs next.
Add an option to control the horizontal scaling of text. This is mainly
to work around text overflow issues in the MangaGamer version of Rance
02 (an appropriate value is set automatically for that game).
Read .xsys4-debugrc from ~/.xsystem4 and/or the game directory on
startup. This is just a text file with one debugger command per line.
Can be used to set breakpoints or log functions automatically at
startup.
This can also be used to work around a limitation on Windows where the
IME doesn't work in the debugger, making it impossible to input Japanese
text.
Add vm-state command, which prints disassembly around the current
instruction pointer and the current contents of the stack.
It was necessary to change how breakpoints are implemented for this.
When adding a breakpoint, the original opcode now remains in the
instruction stream, bitwise-or'd with BREAKPOINT. A hash table indexed
by address is used to store breakpoint objects.
* Add "frame" command to change the current frame.
* Add "members" command to print struct members for current frame (if it's
a method frame).
* Support printing member variables (e.g. "this.var") in the "print"
command.
Gpx2Plus.CopyStretchReduceAMap behaves differently in the English
version.
Fixes an issue with text being squashed horizontally on the regional
phase menus.
System 4 has 4 font weights: light, medium, bold and heavy bold.
SDL_ttf has 2 (normal and bold). For now, xsystem4 treats light/medium
as normal and bold/heavy-bold as bold.
It was a bug to call this function outside of sact_Update, because it
set scene_is_dirty to false without first rendering the scene. This can
cause the scene to not be rendered in a timely manner.
cJSON_AddArrayItem is O(n), which made saving arrays O(n^2). This was
causing extremely poor performance when saving large arrays, such as
those created by MultiSprite_Encode.
A special cJSON_CreateIntArray_cb function is now used instead, which
can create and populate an array in O(n).
