2018-06-21Biome API: Fix absent water decorations and dust, in deep water (#7470)Paramat
Previously, the biomemap was 'BIOME_NONE' for a mapchunk column if a stone surface was not found in it, causing water surface decorations and water surface dust to fail. Store the biome ID of the biome calculated at a water surface and add it to the biomemap if the biomemap is 'BIOME_NONE' for the mapchunk column. The biome calculated at a stone surface still has priority for the biomemap entry, as it should. Edit an incorrect comment.
2018-06-08Mapgen flags: Add 'biomes' global mapgen flag (#7355)Paramat
Previously the only way to disable biomes was to 'clear' the registered biomes in a mod, but this method causes large amounts of unnecessary processing: 1. Calculation of 4 2D noises. 2. Looping through all nodes of a mapchunk replacing nodes with identical nodes. The new flag disables those operations.

2018-04-07Biome API / dungeons: Add biome-defined dungeon nodesParamat
Add new biome fields 'node_dungeon', 'node_dungeon_alt', 'node_dungeon_stair'. If 'node_dungeon' is not defined dungeons fall back to classic behaviour. Remove messy and imprecise dungeon material code from 'generateBiomes()'. Code deciding dungeon materials is now in 'generateDungeons()' and uses the biome at mapchunk centre for more precision. Remove hardcoded 'MG_STONE' types as long intended.
2018-04-05Biome API / cavegen: Add definable cave liquid for a biome (#7192)Paramat
Add 'node_cave_liquid' as a new field in biome registration. If field is absent cave liquids fall back to classic behaviour.

2018-03-11Biome API: Add 'get_biome_name(biome_id)' APIparamat
Change name of default biome to a more suitable lowercase 'default'.
2018-03-09Biomes: Add 'min_pos'/'max_pos' xyz biome limitsparamat
'y_min' and 'y_max' are still accepted for compatibility.
2018-02-20Vertical biome blend: Tune blend patternsparamat
2018-01-16Biomes: Add 'get heat', 'get humidity', 'get biome data' APIsparamat
'get biome data' returns biome id, heat and humidity. Clean up nearby lines in lua_api.txt.

2018-01-05Biomes: Add vertical biome blend (#6853)Paramat
Add 'vertical blend' parameter to biome registration that defines how many nodes above the biome's 'y max' limit the blend will extend.
