This allows playback of videos in encodings other than MPEG-1, e.g. VC-1
used in the English version of Rance VI.
The FFmpeg dependency is optional. If it's not available, the PL_MPEG
backend will be used.
In SACT2 it's declared as int, so any integer can be passed. A Sengoku
Rance mod actually passes 2, but some compilers generate code that
interprets it as false.
After this, xsystem4 uses the global/group save format used by the
original System4, instead of the JSON format. Existing JSON save files
can still be loaded.
This makes save files interoperable between System4 and xsystem4 in some
games, including Sengoku Rance and Toushin Toshi III.
The nanosleep() function in mingw-w64 often sleeps for more than the
specified time. This causes a problem in Rance 6 combat scene, where
the damage popup is noticeably slow.
This adds vm_sleep() that calls SDL_Delay() which uses high-resolution
timer on Windows.
Most of the functionality of gfx_render_texture (draw method, blend
rate) is moved into sprite_render, since this was the only place using
it.
The draw method and blend rate are now stored in sact_sprite objects
instead of textures.
sact_sprite now has two renderers: the old SACT2 renderer (with blend
rate as the only shader parameter) and the new ChipmunkSpriteEngine
renderer, which supports multiply/add colors and the "surface area"
feature from PartsEngine.
Rance Quest now runs up to the first Flash-related function call
(Flash?!?!).
The 3rd argument to the instruction indicates the type of the second
argument. If there are multiple specifiers in the format string, the
first specifier matching the given type is substituted (NOT the first
specifier encountered when processing the format string).
Add 'step' (s) and 'next' (n) commands for single-stepping bytecode.
'step' is the 'step into' type which descends into function calls,
wheras 'next' is the 'step over' type which continues until the next
instruction within the current function.
These HLLs play .mpg movie files (later games use .alm file extension,
but the format is the same, i.e. MPEG-PS) that contain MPEG1 video and
MP2 audio streams.
pl_mpeg.h is the PL_MPEG library (https://github.com/phoboslab/pl_mpeg)
imported from commit 5aeef4d07593be1960a0e4c7fe204809cfae30bd.
This adds a few mixer functions (mixer_stream_*) for playing custom
audio streams under the master mixer.
Now parsed particle-effect definitions are cached in a hash map in the
plugin object. To make it possible, static part of `struct
particle_effect` and `struct particle_object` are factored out to
`struct pae` and `struct pae_object` respectively.
When there are multiple instances of a model, now they share a single
model object. Model objects are retained in a hash table until the
plugin is released, which is fine because Toushin Toshi 3 doesn't reuse
a plugin across scenes.
It visualizes the bounding sphere of the instance. Although it is only
called from dead code in Toushin Toshi 3, it's useful for debugging
shadow mapping.
This fixes broken shadow rendering e.g. when Nacht climbs a ladder.
Now update_bones() calculates the instance's bounding sphere which
is the minimum sphere containing the AABB of current bone coordinates.
This corresponds to the sphere that is displayed when calling
SetInstanceDebugDrawShadowVolume on the original ReignEngine.dll.
This fixes billboard rendering issue in some dungeons.
* For polygon models, use its AABB's center coordinates.
* Consider the camera angle, i.e. sort by view-space Z-coordinate
instead of world-space Z-coordinate.
Some games have assets that are too large to mmap everything on a 32-bit
address space. For example, TT3 has a total of 2.82GB of assets, which
is too large for the 3GB address space limit of 32-bit Linux. On Android
it's even stricter and mmaps of hundreds of MB can fail.
Before this, the order of drawing was determined on an instance-by-
instance basis. Instances with even a single transparent material were
drawn after fully opaque instances.
After this, first the opaque meshes in all instances are drawn, and then
the transparent meshes are drawn from the nearest to the farthest.
- 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.
