As noted in notes/parts-engine.md, many functions have been renamed.
They link to existing PE_ functions.
Some functions have had their arguments or return values changed from
int to float. For now, they just use the existing int functions.
Class members are destroyed in the reverse order of their declaration
(like C++). The previous code destroyed members in declaration order,
which caused a use-after-free in Rance 9's T_Map class.
Added a test to verify the reverse destruction order.
When a delegate finishes calling all registered functions,
variable_fini() was called on the original stack arguments. For ref
types, this results in an unbalanced heap_unref() because the caller
pushes raw ref-values without incrementing the reference count. Non-ref
string/struct/array arguments are not affected because their push
instructions allocate new heap slots with ownership.
This fixes use-after-free in T_Loop@checkSelect in Rance 9.
Two changes from Pastel Chime 3 (likely to make the executables
incompatible):
- SystemService.XXX function
- PartsEngine.Update() has two dummy string parameters
The system.ExistsFile() system call returns 1 if a file or directory
exists, but returns 0 when the provided path ends with a directory
separator, regardless of whether a directory exists at that location.
This subtle difference in behavior caused problems in Pastel Chime 3.
The meaning of the method parameter is the same as that of
StoatSpriteEngine.SP_SetDrawMethod.
This fixes a visual issue in Pastel Chime 3's battle scene.
This allows a specified part to be used as an alpha map (clipper) during
rendering. A dedicated vertex shader (parts.v.glsl) is introduced to
calculate clipping coordinates using an inverse transformation matrix.
Refactored parts_render_text() to use parts_render_texture() so that
alpha clipping is applied to text. This also enables color modifications
for text, while rotation and scaling remain unsupported, matching the
original PartsEngine behavior.
Incremented the parts save version since alpha_clipper_parts_no is now
persisted.
This fixes an issue where thumbnails do not display on the save screen
in Pastel Chime 3.
If `cg_name` starting with "<save>" is passed, the function loads the CG
from the save directory.
Note that unlike GoatGUIEngine.SetPartsCG() in Rance Quest, `cg_name`
does not include "SaveData\\".
This library is for rendering the isometric map grid in Pastel Chime 3.
It manages a background texture and an isometric grid texture. The grid
is generated from a sprite tile and an array representing tile
visibility. It provides functions to create, delete, and copy/blend
these textures onto destination sprites.
This HLL provides functionality for loading, managing, and rendering
animations stored in the MAD file format. A MAD file consists of a
header followed by a series of QNT image frames.
Pastel Chime 3 executes system.GroupSave() with a group name of
"共有データ", but that group name does not exist in the OBJG section of
AIN.
Pascha3.exe does not treat such system.GroupSave() calls as failures,
instead behaving as if saving an empty variable group.
Custom comparison functions for string arrays receive their arguments by
value. Create a copy of the strings before pushing them to the stack to
prevent them from being prematurely freed after the function call.
This appears to be an anti-cheat mechanism. To make save files
compatible, it should do the same calculation as the original,
but for now we just return the values as they are.
