Offset the sprite so that the origin matches the anchor selected by the
graphic key's align field. Use the source rectangle dimensions when an
area is specified, and the full texture dimensions otherwise.
Replace direct one-shot zlib compression and decompression calls with
the libsys4 wrappers. Use exact-size decompression where file formats
provide the uncompressed size.
File2.c continues to depend directly on zlib because it uses streaming
inflate.
This implements rendering of FLAT_LIB_EMITTER libraries: timed spawning,
per-particle motion, fade, and 3-axis rotation.
For each visible emitter, render_flat_emitter() builds an emitter base
matrix from the ancestor key stack so particles follow their parent
timelines. parent_key_mode chooses between filtering ancestor properties
via the emitter's inherit_* flags (SELECTIVE) and using ancestor poses
wholesale (ANCESTOR_CURRENT / ANCESTOR_AT_BIRTH). For each birth frame
in the lifetime window, parts_flat_foreach_emitter_particle() reseeds
the RNG from (rand_seed, birth_frame), making particles deterministic
across re-renders, and yields each particle's pose, which is composed
with the emitter transform and submitted as a quad through the standard
parts texture pipeline.
Memory allocated with xcalloc_aligned (which uses _aligned_malloc on
Windows) must be freed with _aligned_free. Using standard free() caused
heap corruption and crashes.
There is no need to call initialize_instructions() in system4.c, because
ain_open() initializes the instruction set internally when it reads the
VERS tag.
- Add support for setBreakpoints request
- Add source locations to stackTrace response
- Source-level stepIn/stepOut/next executions
All of these only work if debug information is available. Otherwise they
work at the instruction level as before.
Collision detection is based on a mesh named "collision" in the map's 3D
model. The "collision" mesh specifies the area in which the character
can move in the xz plane, and the y coordinate represents the height of
the map at that point.
Now cglm 0.9.2 is required, for 2D AABB operations.
V5 is used until Daiteikoku, and v7 since Rance Quest. Since both are
Ain v6, the save version is determined by the presence of the "MainVM"
field in AliceStart.ini.
Writing save files in RSM format is only enabled if `--save-format=rsm`
command line flag is specified, because this implementation does not
create save files that are fully compatible with the AliceSoft's
implementation:
* There is no simple way to determine the RSM format version used by the
game.
* There are several unknown fields in the RSM format.
* Empty arrays are represented as NULL pages in xsystem4, so type
information of such objects cannot be saved.
These limitations are not a problem for the following use cases:
* Use the created save files only in xsystem4
* Load save files created by System40.exe
Also, RSM save files are much smaller and faster to read and write than
JSON.
And by extension config.save_dir. This fixes an issue where paths
retrieved by system.GetSaveFolderName and then passed to gamedir_path
would become invalid.
Fixes#115
So far only basic debugging functionality is implemented (breakpoints,
stepping, stack traces/variables).
This is not tested against an established DAP client. My intention is to
create a custom GUI frontend and extend the protocol to support
xsystem4-specific features, such as inspecting the scene. (This work is
underway.)
Instruction references are hex-encoded address strings. Clients do not
need to obtain them from DAP requests. This is outside the spec, but it
is needed for a binary-only debugger.
Functions that write directly to stdout (e.g. printf) should generally
not be used any more. Instead, use either sys_message (which respects
sys_silent) or log_message (which will send the message to the debugger
if DAP is enabled). stderr can be used as normal.
When loading a delegate, the stored objects must be registered to it.
Also, delegate_call cannot use vm_execute because the VM cannot be
resumed from such a state.
Incidentally, this means that ResumeSave cannot be called from within a
constructor/destructor (since they also use vm_execute), but this is
probably not a problem.
The game currently runs up until the first unimplemented function
(SeekEndMotion) during the intro events, using the existing PE_
functions with a few minor fixes.
The afa implementation from libsys4 now handles basename indexing, so we
use that instead of creating a separate index. Also, afa v1 is now
properly supported in libsys4, so there is no need for the
id_indexed_afa hack.
Statically link FFmpeg on Windows. This requires building a slimmed-down
version of FFmpeg from source. The build process is documented in the
README.
Also add ffmpeg dependency to the nix flake.
Try to link statically as much as possible on Windows, to reduce the
number of DLLs that have to be shipped with Windows builds.
Also document the build process on Windows.
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 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).
Print usage information when there is an error in the command line
arguments. Also, wait for keypress before exiting on Windows so that the
user can read the error message.
Pointers to `struct font_size` objects are cached in `struct text_style`
objects, so the `sizes` array can't be reallocated.
This fixes a crash in Rance 02 when entering battle.
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).
