41 --[[ These biomes try to resemble MC as good as possible. This means especially the floor cover and
42 the type of plants and structures (shapes might differ). The terrain itself will be of course different
43 and depends on the mapgen.
44 Important: MC also takes the terrain into account while MT biomes don't care about the terrain at all
45 (except height).
46 MC has many “M” and “Hills” variants, most of which only differ in terrain compared to their original
47 counterpart.
48 In MT, any biome can occour in any terrain, so these variants are implied and are therefore
49 not explicitly implmented in MCL2. “M” variants are only included if they have another unique feature,
50 such as a different land cover.
51 In MCL2, the MC Overworld biomes are split in multiple more parts (stacked by height):
52 * The main part, this represents the land. It begins at around sea level and usually goes all the way up
53 * _ocean: For the area covered by ocean water. The y_max may vary for various beach effects.
54 Has sand or dirt as floor.
55 * _deep_ocean: Like _ocean, but deeper and has gravel as floor
56 * _underground:
57 * Other modifiers: Some complex biomes require more layers to improve the landscape.
58
59 The following naming conventions apply:
60 * The land biome name is equal to the MC biome name (in camel case)
61 * Height modifiers and sub-biomes are appended with underscores and in lowercase. Example: “_ocean”
62 * Non-MC biomes are written in lowercase
63 * MC dimension biomes are named after their MC dimension
64
65 Intentionally missing biomes:
66 * River (generated by valleys and v7)
67 * Frozen River (generated by valleys and v7)
68 * Mesa (Bryce)
69 * Hills biomes
70 * Plateau
71 * Plateau M
