2017-09-17Biome API: Revert biomes, decos, ores being relative to water levelparamat
Feature is unnecessary and would greatly complicate future development, it would also make 'get biome at pos' extremely complex. Mgv7: Revert option to repeat surface biomes in floatlands, which depended on the above.

* Modernize various files (src/m*) * range-based for loops * code style * C++ headers instead of C headers * Default operators * empty function Thanks to clang-tidy
2017-08-09Mgv7: Raise spawn point by 1 node for no mountain caseparamat
2017-07-30Dungeons: Use biome 'node_stone' if normal stone types not detectedparamat
Construct dungeons from the node defined as biome 'node_stone' if 'mapgen_stone', 'mapgen_desert_stone' and 'mapgen_sandstone' are not detected. Feature long-intended by kwolekr/hmmmm and present in code as a TODO.
2017-07-26VoxelManip cleanups (const ref, const move) + function removal (#6169)Loïc Blot
* VoxelManip cleanups (const ref, const move) permitting to improve a little bit performance * VoxelArea: precalculate extent (performance enhancement) This permits to reduce extend high cost to zero and drop many v3s16 object creation/removal to calculate extent It rebalance the client thread update to updateFastFaceRow instead of MapBlockMesh generation This will also benefits to mapgen
2017-07-26Mgv7: Add 'mount_zero_level' parameterparamat
Allows setting of the mountain 'zero level' (y where density gradient is zero). It is easy to vertically shift smooth terrain by editing noise parameter 'offset', but vertically shifting mountain terrain was complex and imprecise, involving making a calculation based on an average of the mountain height parameter.
2017-07-22Mgv7: Add option to repeat surface biomes in floatlandsparamat
2017-07-11Biomes/decorations/ores: Make relative to 'water_level' settingparamat
Add 'biome_zero_level' argument to 'generateBiomes()', 'deco_zero_level' argument to 'placeAllDecos()' and 'ore_zero_level' to 'placeAllOres()' to allow mapgens to vertically shift the registered biomes, decorations and ores per-mapchunk. Will also allow many realm possibilities in future mapgens.
2017-06-30Mapgen: Remove unnecessary 'this->' from constructors (#6069)Paramat
2017-06-28Mgv7: Fix undefined 'float_mount_height'paramat
Commit cad10ce3b747b721fd63784915e05f12bc488128 altered the parameter 'float_mount_height' but was missing the necessary line in the constructor to get the altered value from 'params'. Fixes 3D floatland terrain generating everywhere.
2017-06-25Mgv7: Clean up divide-by-zero fixparamat
2017-06-24Mgv7: Avoid divide-by-zero errorsparamat
Some settings of paramters can cause mgv7 variables to be -inf, nan or -nan. This can cause massive vertical columns of water to appear above sea level.
2017-06-22CavesRandomWalk: Make 'lava_depth' a mapgen parameterparamat
As with 'large_cave_depth', lava depth was previously a fixed y value and therefore incompatible with the ability to shift terrain vertically. Add 'lava_depth' mapgen parameter to mgflat, mgfractal, mgv5, mgv7.
2017-06-21Mgv5/v7/fractal: Add 'large_cave_depth' parameter to replace fixed valueparamat
The value cannot be fixed because we can shift terrain vertically. This also makes these mapgens consistent with mgflat and mgvalleys which have 'large_cave_depth' parameters.
2017-06-19Mgv7: Do not limit river generation if no floatlandsparamat
Previously, the carving of rivers was disabled above 'shadow_limit' even if floatlands were disabled. This caused rivers to be unnecessarily disabled if mapgen was customised to have surface level above y = 1024.
2017-06-19Mgv7 spawn search: Cope with extreme custom terrain and biome 'dust'paramat
Previously, maximum spawn level was set to 'water_level + 16'. This would result in spawn search failing if terrain had been customised to be much higher than 'water_level' at all points. Also raise spawn level by 1 node to avoid spawning half-buried in a biome 'dust' node such as 'default:snowblock'.
2017-06-17Cpp11 initializers 2 (#5999)Loïc Blot
* C++11 patchset 10: continue cleanup on constructors * Drop obsolete bool MainMenuData::enable_public (setting is called with cURL in server loop) * More classes cleanup * More classes cleanup + change NULL tests to boolean tests

2017-05-16Caverns: Remove unnecessary liquid excavationparamat
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.
2017-04-22Mgflat, Mgv7: Fix noise crash on world exit.paramat
Fix crash caused by destructor 'delete' on noise objects that are not created due to mapgen options. Crash was caused by commit 57eaf62c697cec91890d9cb28d10385d293d2d3f
2017-04-22Mgflat, Mgv7: Only create noise objects if neededparamat
2017-04-05Mapgen: Remove '#include treegen.h' from non-mgv6 mapgensparamat
Only mgv6 uses the tree functions from treegen.cpp.
2017-04-03Cavegen/Mgv5/Mgv7: Add optional giant cavernsparamat
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.
2016-12-13Mgv7: Change default cave width to 0.09sfan5
2016-12-01Mgv7 floatlands: Various improvementsparamat
Floatland base terrain underside was too thin, causing excessive water leakage through tunnels under lakes, now make it thicker. Floatland mountain terrain had a rim 1 node thick which made it bare stone, now make it 2 nodes thick to merge with the floatland base terrain rim and to have a layer of biome material. Make mountain terrain more exponentially shaped by altering the exponent. Remove unnecessary and potentially ugly MYMAX() applied to n_base_height.
2016-11-15Mgv7: Add optional floatlands, disabled by defaultparamat
2016-09-30Mgv7: Avoid mid-air spawn on disabled mountain terrain, optimise functionparamat
'getSpawnLevelAtPoint()' did not account for disabled mountains, it was possible to be spawned in mid-air where a mountain surface would have been. Avoid check for river area if rivers are disabled.
2016-07-03Add MapSettingsManager and new mapgen setting script API functionskwolekr
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.
2016-06-24Mgflat/fractal/v7/valleys: Denser 3D noise tunnelsparamat
Reduce spread from 96 to primes 61 and 67 (either side of 64) Prime spreads help to keep 3D noise periodic features unaligned 'cave width' 0.2 to preserve tunnel width Reduce octaves to 3 to improve network structure
2016-06-05Mapgen: Optimize biomemap creation by combining with generateBiomeskwolekr
2016-06-02Mgv7: Always carve river channels in mountain terrainparamat
Previously, rivers were sometimes blocked by vertical walls of mountain terrain due to river carving being disabled when base terrain height was below water_level - 16 Remove now unused base terrain heightmap created in generateTerrain()

2016-05-27Mapgen: Deduplicate common constructor codekwolekr
2016-05-27Mapgen: Remove calculateNoise from most mapgenskwolekr
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.
2016-05-27Mapgen V7: Remove now-unused ridge heightmapkwolekr
2016-05-27Cavegen: Move V5-style caves to CavesNoiseIntersectionkwolekr
2016-05-27Fix MgStoneType and BiomeType enum nameskwolekr
2016-05-27Mapgen: Combine generateBiomes, dustTopNodes, and generateCaveskwolekr
This commit condenses the above methods into a single implementation used by V7, V5, Flat, Fractal, and Valleys mapgens and introduces MapgenBasic.
2016-05-27Move biome calculation to BiomeGenkwolekr
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.
2016-04-28Mapgen: Make 3D noise tunnels' width settableparamat
Correct parameter names mg_valleys to mgvalleys Remove biome NoiseParams from MapgenValleysParams Improve format of parameter code
2016-04-20Mgv7: Combine mountain terrain generation with base terrain generationparamat
Previous mountain terrain generation was by necessity placing stone in air, this was removing air from any overgenerated structures such as tunnels, dungeons and large caves Moving it into the base terrain generation loop ensures that only 'ignore' is replaced generateRidgeTerrain: only return if node_max.Y < water_level - 16 Previously, if water level was set a few nodes above a mapchunk border the river channel was only partially excavated
2016-04-12Mgv7, mgflat, mgfractal: Tunnel generation code optimisationparamat
2016-04-08Mapgen: Optimise cave noises and tunnel excavationparamat
Instead of doing nothing at node_max.Y + 1 use 1-down overgeneration for tunnel generation and noisemaps Move some old unused code in mgv7 to end of file
2016-03-30Mgv7: Decrease cliff steepnessparamat
2016-03-21Mgv7/flat/fractal: Stop tunnel-floor biome nodes being placed everywhereparamat
A bool for 'in or under tunnel' was missing 1-node-deep stone ledges were being replaced with biome surface material
2016-03-19Mgv7: Limit pseudorandom caves to surface mapchunk or belowparamat
To avoid bright caves at mapchunk borders when generating mapchunks upwards
2016-03-14Mapgen: Fix light in tunnels at mapchunk bordersparamat
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.
2016-02-09FindSpawnPos: Let mapgens decide what spawn altitude is suitableparamat
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
