Ensure that sact_get_sprite always returns a sprite object if sprite
number is not negative. SACT2 functions in general should work before
pixel data is attached to a sprite.
This also fixes the default for the 'show' property (true) and changes
the logic for adding/removing sprites from the scene to be less
error-prone (checked whenever a sprite is dirtied).
Implement the SP_SetText* and MultiSprite_* functions added by
StoatSpriteEngine (as well as the TRANS_* functions introduced in
SACTDX). Enough to get to the opening movie in Vanish!
Split the code from sact_graphics.c into sprite.c and hll/SACT2.c.
sprite.c contains an index-independent sprite/scene interface, whereas
hll/SACT2.c handles the indexing of sprites.
This is to better support the StoatSpriteEngine.MultiSprite_* functions,
which use a different indexing system.
ref types are currently passed to HLL functions as pointers into the
heap. If the HLL function itself needs to allocate memory from the heap,
it can cause the heap to be reallocated, rendering these heap pointers
invalid.
In order to work around this, hll_call now guarantees 64 slots are
available on the heap before calling any HLL function. This is not a
great solution, but it should work to the extent that HLL functions only
allocate a fixed number of heap slots < 64.
This bug could be easily triggered by scrolling up on the message log in
Sengoku Rance.
MacOS does not support OpenGL compatibility profile, so the following
changes had to be made:
- Replaced deprecated texture2D() with texture() in shaders
- Renamed `texture` uniform variable to `tex`, to avoid name conflict
- Use VAO, which is mandatory in OpenGL 3 core profile
These functions should NEVER return a pointer into the ain object, since
its storage can be realloc'd. Now all get/add functions return an index
which can safely be stored for later use.
Stack traces now list addresses in addition to function names.
Additionally, debugger stack traces number each frame, and the numbers
can be used together with the PRINT-LOCALS function to print the values
of local variables for any frame on the stack.
This is implemented by inserting special opcodes into the game's code.
When the breakpoint handler is finished, it returns the original opcode
so that execute_instruction can continue executing normally.
E.g.
* start xsystem4 with --debug option to drop into debugger immediately
* run (bp "game_main")
* ^d or \exit to close debugger REPL
* ...drop into a debugger REPL again at the game_main function
global config in $XSYSTEM4_HOME/.xsys4rc (default ~/.xsys4rc)
game-specific config in <game-dir>/.xsys4rc
Supported options so far are "font-mincho" and "font-gothic". Syntax is
the same as System40.ini. E.g.
font-mincho = "/home/user/.fonts/msmincho.ttc"
Even though this game is still ain v14, it makes an incompatible change
to the file format: struct definitions now contain a list of functions
at the end (I believe this is a listing of the struct's vtable).
There is now a system for tracking the minor version of the ain file
format. This is a made up value, determined by the file name of the ain
file.
This commit also fixes an issue where the empty string was being added
as a new string to the string table when rebuilding ain files with
ainedit.
SDL_mixer reads loop information from WAV files if you use the Mix_Music
interface, but NOT the Mix_Chunk interface. So bgm now uses the
Mix_Music interface to get proper looping.
There's also some code here for reading bgi files (taken from xsystem35)
but it's not actually used. There doesn't seem to be a simple way to set
up custom loops with SDL_mixer.
Fixes#2.
The problem here was that init_member_functions assumed ASCII or SJIS
encoding of function/struct names in the ain file. Now it will convert
to UTF-8 when analyzing member functions.
This commit also removes the --ain-encoding option to ainedit.
--output-encoding should always match the encoding of the input ain
file. --transcode can be used to change the encoding before running
running further ainedit commands.
This is mainly for testing purposes. Defaults to creating an ain v4
file, which is the same version produced by the SDK compiler.
Also various small improvements so that output matches the SDK compiler:
* add "0" function (currently does nothing)
* add "NULL" function
* compile null return at the end of every function
* set main function index in ain file
