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.
Each delegate call needs to copy its arguments so that they aren't
double-freed by the next call.
Also fix a bug in FT_ASSIGNS where -1 was returned for non-existant
functions instead of 0.
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.
The parent's z-value determines the render order of its children.
Alicesoft's implementation of this is a bit weird. The render order only
changes when the parent's visibility is toggled (via Parts_SetShow), NOT
when the parent is set on a child or the parent's z-value changes.
I have chosen to implement this so that the render order is always based
on the current parent/child z-values.
This fixes some bugs in Rance 01.
Fixes a crash bug when attempted to get a string property of nonexistent
motion.
This also fixes compiler warnings, and simplifies the code by using
helper functions.
Move position/size values around and rename them to reflect what they
actually mean:
* parts->offset moved to parts_common->origin_offset
* parts->pos moved to parts_common->hitbox
* x and y coordinates from parts->rect renamed to parts->pos
* width and height from parts->rect moved into parts_common
Check for uninitialized or explicitly zeroed surface area at render
time. This fixes an issue where some construction process parts would
not be rendered (specifically, the button text on the Rance 01 title
screen).
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.
