Use noises to create a varying mix in coniferous forest biomes:
Areas of large pines only, areas of small pines only, mixed areas.
While also having areas of high and low tree densities.
Saplings grow into large or small pines with equal chance.
Acacia bush: Create a unique form different to normal bush, with more
leaf nodes at top than at base.
Acacia tree: Maximum height increased by 1 node. 2 extra nodes of
height variation.
Jungle tree: Add an extra node of height variation. Y-slices moved
downwards to be more balanced between trunk and branches, makes
branches more common.
Pine tree: Increase maximum height by 1 node. Add an extra node of
height variation.
Update sapling 'on place' protection checks for acacia and pine trees.
Denser jungletree for darker rainforest:
Highest 'jungletree' nodes now prob 255.
Add a 5th lower branch layer.
Increase lower branch layer y-slice prob to 191.
Aspen:
Extend trunk upwards by 1 node to reduce leafdecay radius to 2.
Pine:
Make lower trunk 1 node longer so that lowest branches are more often
higher off the ground, also to make pines taller.
Appletree:
Make 2 opposite branches prob 255, the other 2 prob 127, to avoid
trees with 1 or 0 branches. Therefore also add random rotation.
Papyrus:
Make base node dirt instead of dirt_with_grass. Formerly the exposed
dirt would change to grass but the new grass spread ABM now prevents that.
Waterlily:
Don't specify a water_source node in the schematic, as it may be used in
river water. It was not force-placed but should really be "air" prob = 0.
Biomes:
Add 'sandstone desert', 'cold desert', 'snowy grassland'.
Rename 'glacier' biome to 'icesheet' biome.
Rename non-swamp 'swamp' biomes to 'shore' biomes.
Remove 'sandstone grassland' biome.
Rename 'stone grassland' biome to 'grassland' biome.
Edit biome points for improved similarity to Whittaker classification.
Change 'tundra' to bare stone with snowblocks.
Make dirt 'swamp' / 'shore' less deep.
Ores:
Make dirt blob ore biome-specific, limit to dirt biomes.
Decorations:
Make mushroom noise spread match that of appletrees as originally intended,
to have mushrooms spawn in darker thicker forest areas.
Add coral reefs in warm oceans.
Add bushes and acacia bushes.
Jungletrees in deeper water for larger swamps.
Register flower mod decorations in singlenode mapgen for use by
minetest.generate_registered_decorations, as in default/mapgen.lua.
Adds a birch-like tree to the default_game. Aspen was chosen on
purpose instead of birch, as several birch tree mods already exist
and choosing a different name avoids any conflicts.
Schematics were made for both normal and sapling version, assuring
saplings will not be able to grief. The shape of the Aspen is "fanning
out at the top" and provides an easy tree to walk under, but still a
somewhat thick cover. The Aspen trunk is 4 to 6 blocks tall, with up
to three layers of leaves on top, making it slightly taller than an
Apple tree, but shorter than a Pine tree, which provides a good blend.
Textures were painted from scratch, except tree_top and _wood
variants, which are color modified versions of the pine_wood
variants. Appropriate licenses have been chosen for the new textures.
The leaf texture is light enough to contrast other trees, but dark
enough to offset against our light default grass color. The leaves
are drawn in the typical minetest default fashion with plenty of
transparancy, but enough definition to suggest that you're seeing
something that looks like leaves. The placement of leaves in the
schematic also suggests the top of the tree is sparse and you can
see the sky through the leaves.
Sapling texture is both traditional and different, with lush green
leaves and a well-defined stem, but slightly stick-like and skinny,
as these plants tend to grow up first, then out.
Add fallen Aspen logs. We make these logs a minimum of 2 blocks long,
and up to 3. This allows us to make these logs a place where both
red and brown mushrooms can be found, to these may be attractive to
players. However, the spawn rate for these has been reduced a lot
compared to the other logs, to account for the scarcity of Aspen.
Add stairs, slabs for these wood types as well.
Mapgen will place these trees in deciduous forests only, but in
a way that the biome is a range between entirely Apple trees, and
mostly entirely Aspen trees, with a bias to Apple trees. To make
fallen logs somewhat correlated with trees, we modify the planting
of Apple trees and logs to use perlin noise and not fill ratio,
otherwise you'd always end up with Apple logs in Aspen tree areas,
which would be suspicious. There still is a bit of a mix.
Dirt waters are more suitable for waterlilies
Add dedicated dunes biome in coniferous forest
Papyrus: use dirt base again
Force-place roots on mapgen tree schematics
Tune some humidity points to improve voronoi cells
Add random rotation to jungle trees
More complex distribution of dry grasses
Remove water below glacier rivers
Gravel as glacier seabed
Do not force-place acacia root
Tune acacia tree density
Match mgv5/v7 mushrooms to tree density
Spawn mgv6 mushrooms by trees
