Previously, maximum flora density was chosen based on the extremely rare
occurrence of all 8 flowers being at high density at one location. This
caused flora everywhere to spread to an unacceptably high density.
Revert the threshold to 3, which in testing results in a more acceptable
maximum density of 7 flora per 9x9 area.
Match maximum spread density to maximum mapgen density for flowers.
Place 3 flora nodes at once instead of 1.
Change ABM chance value to 300 to match previous spread rate.
ABM becomes 3 times less intensive.
Adds a direct resource of green dye, and a flower resource of black dye.
Completes the colour sequence: red, orange, yellow, green, blue, violet.
Makes all base dyes cultivatable and sustainable, without the presence
of coal.
Add the new flowers to the world with the same density variation as the
others, but obviously with different noise seeds. Results in more flowers
in a world and more variety of flower combinations.
Only register floatland biomes if mgv7 'biomerepeat' flag is false.
Simplify floatland biomes to coniferous forest and ocean.
Make 'mgv7_floatland_level' and 'mgv7_shadow_limit' parameters global
values for mods to use to register their own floatland biomes.
Flora is converted to dry shrub in desert sand and silver sand.
No conversion in sand to preserve sand dune grasses.
Dry shrubs do not spread so this conversion, used by players, is the
only way to generate them.
If there is no group:soil node found below, do not replace flora with
dry shrub, this was breaking flower pots and other mods.
Originally, flora would only turn to dry shrub if in desert sand.
Use the soil group more instead of checking for multiple node names.
Remove 'neighbors' from ABM.
Turn any flora to dry shrub if on a non-soil, except when on default:sand
to avoid dune grasses being replaced.
Search for "group:soil" when searching for a position for the new flora
node, instead of searching for multiple node names, however do not spread
flora onto desert sand, which is in the soil group.
Remove default:dirt_with_snow from the soil group as it would be frozen
soil. It can be dug and placed to turn it into dirt (consider this some
extra work needed to make it cultivatable).
A simple set of biomes for now: Ocean, coniferous forest, grassland,
sandstone desert.
Update biome lists for blob ores and decorations.
Make sandstone desert filler 1 node deeper to match other deserts.
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.
With mip-mapping enabled, some GPUs cause a visual bug with indexed
textures that use alpha. This bug has been present for a while but
not noticed before. All indexed alpha textures must now be converted
to RGBA, to start this process we revert some textures converted to
indexed in the recent commit af3c918.
