- Enable both alpha map and alpha mod, using the new drawing function
gfx_copy_stretch_blend_amap_alpha().
- Do not draw if `bcg->show` flag is false.
- Do not WARNING() for SetBackCGNum(0) as it's used to unload the CG.
This implements a parser for particle effect definition files (.pae)
and a set of field accessor functions for the RE_ITYPE_PARTICLE_EFFECT
instance type. Rendering of effects is not yet implemented.
There are two types of fog, linear fog and atmospheric scattering. The
formula for light scattering is incorrect (see the comment in
reign.v.glsl) and therefore not physically correct.
This is used to compute Y-positions of map objects.
It is called quite often, so this implementation creates and caches a
height map of the instance by (re)using the shader for shadow mapping.
This implements a Phong shading with ambient, diffuse and specular
components, using up to three directional lights and one specular light.
The light calculation is made to match the "high quality" 3D mode of
Toushin Toshi 3.
Parent-child relationships are established by the UpdateComponent
function. Parts_SetParentPartsNumber does not establish the relationship
(and it does not create the parent object if it does not exist yet).
Render params are now computed recursively on children when they are set
on the parent (instead of recomputing them every time a child parts is
rendered).
* SetAddColor and SetMultiplyColor implemented
* additive draw filter implemented
* GetPartsUpperLeftPos{X,Y} implemented
* various parameters are now applied from parent to child parts
* misc. bug fixes
The first dungeon screen in Rance 01 now renders correctly.
Implement Parts_SetNumeralLinedCGNumberWidthWidthList and
Parts_SetNumeralLength.
Also fix bugs where changing numeral properties would not update the
texture until the number was reset.
Plugins can implement this so that scene_print will print additional
information for the sprite. RE_plugin implements this to dump the 3D
scene information.
Add a scene_print function which prints a textual representation of the
current scene. This works by attaching a `debug_print` function to each
entity in the scene. This function is implemented for SACT2 and
GUIEngine entities. A default implementation will be used of none is
provided.
This can be accessed from the debugger via the `scene` command (although
the output is typically too much to view in a terminal; it's better to
run `scene_print` somewhere and redirect stdout to a file).
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).
