Previously, the only way to disable the 3D noise tunnels was to set
'cave width' > 1.0, however doing so did not disable the very intensive
noise calculations or the generation loop.
All the other types of cave generation (randomwalk caves, caverns)
can already be independently and completely disabled.
This feature is now needed more because the small randomwalk caves are
now available for use as an alternative to the 3D noise tunnels.
Add mapgen parameters to set the range of the random number of
randomwalk caves per mapchunk, and to set the proportion that are
flooded with liquids.
Default values are, for now, unchanged from the previous hardcoded
values.
Add parameters to allow small randomwalk caves
Disabled by default for now as they have never been present in the
non-mgv6 mapgens.
Revert gamma upper limit to 3.0 because that was raised based on
a misunderstanding and had no benefit. A sane upper limit is
needed as players on a competitive server tend to use the maximum.
Set gamma lower limit to 0.33 for consistency with 3.0.
Set sane limits on alpha, beta, boost and enforce these in code
to limit values entered in minetest.conf and to avoid easy cheating
by editing settingtypes.txt.
Improve documentation and 'readable' setting names.
Clarify that gamma does not significantly affect natural night light.
light.cpp: Various codestyle and comment improvements.
All on_* hooks that return an itemstack are NOT guaranteed to
modify and return the original stack. We cannot count on the
behavior of the existing builtin definitions not to be overridden
by game/mod logic.
This value reduces how far randomwalk caves can extend into the
mapchunk padding, to avoid 'out of voxelmanip' cave nodes which cause
flattened cave walls.
Testing shows that a value of 2 (instead of 10) is enough to make
'out of area' nodes extremely rare.
Reducing this value results in a higher chance of overlap and
connection with caves of neighbour mapchunks.
- Add style properties for overriding the the hovered/pressed state
- By default, hovered buttons are a lighter version of the base color
- By default, pressed buttons are a darker version of the base color
- Add hovered bg image support for image buttons (style property)
This reverts commit 1db3d252cff9e8d61fecf1052d7497813851da51.
Temporary solution until a compatible solution is found to define both - formspec and fullscreen backgrounds.
