Used for the treasure chest opening effect in Rance Quest.
Implemented using draw_plugin. The render() method of draw_plugin is no
longer dedicated to custom sprites, but can be used for any sprites to
override the default sprite rendering function.
It is called when the plugin is unbound from a sprite, or when the
sprite to which the plugin is bound is released.
This prevents memory leaks when sprites are destroyed without the plugin
being released, and simplifies lifetime management of the DrawDungeon
plugin.
Used in Tsuma Shibori, and some indie System 4 games.
This HLL is a draw plugin that uses SACT2's "custom sprite" mechanism.
Custom sprites do not have a texture. Instead, the plugin's render()
callback draws them directly to the main surface.
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.
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.
