--[[ These biomes try to resemble MC. This means especially the floor cover and the type of
plants and structures (shapes might differ). The terrain itself will be of course different and
depends on the mapgen.
Important: MC also takes the terrain into account while MT biomes so far don't care about the
terrain at all (except height).
MC has many “M” and “Hills” variants, most of which only differ in terrain compared to their original
counterpart.
In MT, any biome can occour in any terrain, so these variants are implied and are therefore
not explicitly implmented in MCL2. “M” variants are only included if they have another unique feature,
such as a different land cover.
In MCL2, the MC Overworld biomes are split in multiple more parts (stacked by height):
* The main part, this represents the land. It begins at around sea level and usually goes all the way up
* _ocean: For the area covered by ocean water. The y_max may vary for various beach effects.
Has sand or dirt as floor.
* _deep_ocean: Like _ocean, but deeper and has gravel as floor
* _underground:
* Other modifiers: Some complex biomes require more layers to improve the landscape.
The following naming conventions apply:
* The land biome name is equal to the MC biome name, as of Minecraft 1.11 (in camel case)
* Height modifiers and sub-biomes are appended with underscores and in lowercase. Example: “_ocean”
* Non-MC biomes are written in lowercase
* MC dimension biomes are named after their MC dimension
Intentionally missing biomes:
* River (generated by valleys and v7)
* Frozen River (generated by valleys and v7)
* Hills biomes (shape only)
* Plateau (shape only)
* Plateau M (shape only)
* Cold Taiga M (mountain only)
* Taiga M (mountain only)
* Roofed Forest M (mountain only)
* Swampland M (mountain only)
* Extreme Hills Edge (unused in MC)
TODO:
* Better beaches
* Improve Extreme Hills M
* Desert M (desert lakes - removed?)
