* Caverns: Remove unnecessary liquid excavationparamat2017-05-16
| | | | | | | | | | | | | | | Also disable CavesRandomWalk at a safer distance from caverns. Excavating liquids in cavern code is unnecessary as in practice we are already successfully disabling the generation of liquid caves that could intersect with caverns and cause excessive amounts of spreading liquids in caverns. However to be safer this commit now disables liquid caves at a larger distance from caverns, to compensate for liquid caves being able to generate up to a mapblock beyond a mapchunk border. Not excavating liquids in cavern code also allows a feature i am working on in experimental new core mapgens, but also allows for more flexibility in future.
* Mapgen: Remove '#include treegen.h' from non-mgv6 mapgensparamat2017-04-05
| | | | Only mgv6 uses the tree functions from treegen.cpp.
* Cavegen/Mgv5/Mgv7: Add optional giant cavernsparamat2017-04-03
| | | | | | | | | | | | | | Add to MapgenBasic for use by multiple mapgens. Add to mgv5 and mgv7, enabled by default. Similar to mgvalleys caverns but half the scale. Parameters for upper y limit, distance caverns taper to full size, and noise threshold (full cavern size). As with mgvalleys caverns are generated first and classic caves are disabled in any mapchunk containing a cavern, to avoid excessive spreading volumes of liquids. This also avoids floating blobs of liquid where a large classic cave has overgenerated out into a neighbouring previously-generated mapchunk.
* Add MapSettingsManager and new mapgen setting script API functionskwolekr2016-07-03
| | | | | | | | | | | | | | | This commit refactors the majority of the Mapgen settings system. - MapgenParams is now owned by MapSettingsManager, itself a part of ServerMap, instead of the EmergeManager. - New Script API functions added: core.get_mapgen_setting core.get_mapgen_setting_noiseparams, core.set_mapgen_setting, and core.set_mapgen_setting_noiseparams. - minetest.get/set_mapgen_params are deprecated by the above new functions. - It is now possible to view and modify any arbitrary mapgen setting from a mod, rather than the base MapgenParams structure. - MapgenSpecificParams has been removed.

* Mapgen: Remove calculateNoise from most mapgenskwolekr2016-05-27
| | | | | | This commit moves noise calculation to the functions where the noise is actually required, increasing the separation of concerns and level of interdependency for each mapgen method. Valleys Mapgen is left unmodified.

* Mapgen: Combine generateBiomes, dustTopNodes, and generateCaveskwolekr2016-05-27
| | | | | This commit condenses the above methods into a single implementation used by V7, V5, Flat, Fractal, and Valleys mapgens and introduces MapgenBasic.
* Move biome calculation to BiomeGenkwolekr2016-05-27
| | | | | | | BiomeGen defines an interface that, given a set of BiomeParams, computes biomes for a given area using the algorithm implemented by that specific BiomeGen. This abstracts away the old system where each mapgen supplied the noises required for biome generation.
* Mapgen: Make 3D noise tunnels' width settableparamat2016-04-28
| | | | | | Correct parameter names mg_valleys to mgvalleys Remove biome NoiseParams from MapgenValleysParams Improve format of parameter code
* Mgv5: Optimise tunnels, add biome material in entrancesparamat2016-04-12
| | | | | | Place biome top node on tunnel entrance floor Instead of doing nothing at node_max.Y + 1 use 1-down overgeneration for tunnel generation and noisemaps
* Mapgen: Fix light in tunnels at mapchunk bordersparamat2016-03-14
| | | | | | Don't excavate the overgenerated stone at node_max.Y + 1, this creates a 'roof' over the tunnel, preventing light in tunnels at mapchunk borders when generating mapchunks upwards.
* FindSpawnPos: Let mapgens decide what spawn altitude is suitableparamat2016-02-09
| | | | | | | | | | | | To avoid spawn search failing in new specialised mapgens Increase spawn search range to 4000 nodes Add getSpawnLevelAtPoint() functions to EmergeManager, class Mapgen and all mapgens Remove getGroundLevelAtPoint() functions from all mapgens except mgv6 (possibly to be re-added later in the correct form to return actual ground level) Make mgvalleys flag names consistent with other mapgens Remove now unused 'vertical spawn range' setting
* Mgv5/v7/flat/fractal: Move tunnel noise calculation into generateCavesparamat2016-02-02
| | | | | | | | | | Tunnel 3D noises are only calculated when solid terrain is present in mapchunk, avoiding large amounts of unnecessary calculations Change 'int' to 's16' in calculateNoise Change 'i' to 'vi' for voxelmanip indexes for consistency Keep 'u32 index3d' local to a smaller part of tunnel code Mgv7: Don't call CaveV7 if no solid terrain in mapchunk Give 'open' bool a more descriptive name
