The Eternity-based definitions are currently disabled due to unclear semantics and overall unsatisfying design. They can be re-enabled once their precise working has been established.
New properties were added to replace them with something that will be clearly specified and is fully ortohonal i.e. they will allow to align an upper tier skew with the floor as well and a lower tier's skew with a ceiling.
While 'block players' was just a simple remap, 'block land monsters' required quite a bit of work...
This also fixes the bug that BLOCK_FLOATERS was never checked for sliding against a wall.
It can now be used from UDMF and ZScript.
To avoid clutter it doesn't allow setting the values individually but requires definition of a data record in TEXTURES.
colorization
{
DesaturationFactor <float>
Invert
AddColor <color>
ModulateColor <color>
BlendColor <color>, <mode> [, <alpha>]
}
Mode for BlendColor can be Alpha (normal translucent blending), as well as 3 special values taken from Build engine games: Screen, Overlay and HardLight.
It makes little sense exposing every minute detail of this through UDMF.
Setting it up that way is far too complicated. Using virtual textures that map to a real texture plus a colorization record should be far easier to use by mappers.
This also doesn't piggyback on the Doom64 color feature anymore and is completely separate, despite some redundancies.
This is still missing the texture definition part, though.
Add 'useowncoloradd_{top,mid,bottom}' sidedef properties to the UDMF
spec
Only use side's additive colors if 'useowncoloradd_(top|mid|bottom)' is
set.
Rename UseOwnColors flag to UseOwnSpecialColors
Add UseOwnAdditiveColor flag to side_t::part
Add EnableAdditiveColor to side_t
Add Side.EnableAdditiveColor to ZScript API
* Colors can npw be defined per sidedef, not only per sector.
* Gradients can be selectively disabled or vertically flipped per wall tier.
* Gradients can be clamped to their respective tier, i.e top and bottom of the tier, not the front sector defines where it starts.
The per-wall colors are implemented for hardware and softpoly renderer only, but not for the classic software renderer, because its code is far too scattered to do this efficiently.
With no 3D floors this appears to be ok, but there are so many places where colormaps are being set in the software renderer that I cannot guarantee that I got all of them correct. This will need some testing.
- for explicitly defined glows, use the one for the current animation frame, if an animated texture is active. For default glows it will still use the base texture's to avoid inconsistencies.
'ceilingterrain' is needed because the top of 3D-floors refers to the model sector's ceiling, so in order to give a 3D floor a terrain it must be assignable to the sector's ceiling.
Note that although it is basically the same property, its actual function bears no relevance to its use in Eternity.
- major overhaul of the static sector damage system:
* consolidated special based damage, Sector_SetDamage and UDMF properties into one set of damage properties. The parallel handling that could lead to double damage infliction was removed. This also means that damage through sector specials can be retroactively changed through Sector_SetDamage.
* all special cases were turned into flags. The new system can switch between Strife's delayed damage and regular damage, and it can also set whether terrain splashes are used or not. It also has access to the special properties of the end-level type (i.e. switching off god mode and ending the level.)
* the damage related flags are accessible through Sector_ChangeFlags, not the damage functions themselves.
