* Move duplicated mapgen parameters to class MapgenBasic (#9134)Paramat2019-11-19
| | | 'large_cave_depth', 'dungeon_ymin' and 'dungeon_ymax' are duplicated across many mapgens so should have been in class MapgenBasic from the start.
* Randomwalk cave liquids: Remove deprecated 'lava depth' parameter (#9105)Paramat2019-11-18
| | | | | | | | | Low-disruption first step towards removing the hardcoded cave liquid code. Since MT 5.0.0 cave liquids can be defined and located by biome definitions instead. In games that do not yet use biome definitions to define and locate cave liquids (MTGame does), lava will now appear below y = water_level - 256 instead of below 'lava depth' (usually y = -256). Therefore no change in most mapgens if using the default 'lava depth'.
* Randomwalk caves: Add parameters for number, proportion flooded. Allow small ↵Paramat2019-11-08
| | | | | | | | | | | | | | caves (#8928) Add mapgen parameters to set the range of the random number of randomwalk caves per mapchunk, and to set the proportion that are flooded with liquids. Default values are, for now, unchanged from the previous hardcoded values. Add parameters to allow small randomwalk caves Disabled by default for now as they have never been present in the non-mgv6 mapgens.
* Dungeons: Settable density noise, move number calculation to mapgens (#8473)Paramat2019-06-01
| | | | | | | | | | | | Add user-settable noise parameters for dungeon density to each mapgen, except V6 which hardcodes this noise parameter. Move the calculation of number of dungeons generated in a mapchunk out of dungeongen.cpp and into mapgen code, to allow mapgens to generate any desired number of dungeons in a mapchunk, instead of being forced to have number of dungeons determined by a density noise. This is more flexible and allows mapgens to use dungeon generation to create custom structures, such as occasional mega-dungeons.
* mapgen: drop mapgen id from child mapgens.Loïc Blot2019-03-31
| | | | | | This id must be owned by the child mapgen and never be set to a misc value by a developer Also use nullptr in some places
* Valleys mapgen code rewrite (#8101)Paramat2019-03-14
| | | | | | | | | | | | Shorter, simpler, clearer and more consistent with other mapgens, while preserving functionality. Base terrain shape is unchanged. With the 'vary river depth' option disabled, river surface level is unchanged. Behaviour of the 4 heat/humidity/river depth options is very slightly changed due to bugfixes and code cleanup (the mapgen is 'unstable'). Apply heat and humidity gradients above water_level instead of above y = 0.
* Mgvalleys: Make river depth variation and humidity drop optional (#7532)Paramat2018-07-18
| | | | | | | | | | | Add 2 new mapgen flags to make river depth variation and humidity drop with altitude independently optional, instead of both being enabled by the 'humid rivers' flag. Simplify and clarify related code by removing a low priority optimisation regarding 't_heat'. Remove unnecessary optimisation bools and use spflags directly instead. Improve and fix documentation in settingtypes.txt. A few minor code cleanups.
* Mgvalleys: Code cleanupParamat2018-04-24
| | | | | | | | | | | Split some long lines. Edit comments. Remove unnecessary comments and unnecessary commented-out code. Use std::fmax/fmin instead of MYMAX/MYMIN. Remove scope-limiting braces. Consistently define literals as floats, except in noise parameters. Cleanup literals in noise parameters. Remove unnecessary 'near_cavern' line. Reduce max spawn y to be consistent with other mapgens.
* Mgvalleys: Use shared tunnel / cavern code instead of internalParamat2018-04-21
| | | | | | | | | | | | | | | | Caverns first appeared in mgvalleys and were later added to other mapgens as shared code. Now this shared code can replace mgvalley's internal cavern code. Also use shared tunnel code instead of internal code. Changes to mapgen that will affect existing worlds (mgvalleys is not stable): Single lava and water sources not added in tunnels. Previous caverns are unchanged but an equal number of new ones are added at a distance from the previous. From y = -256 to 192 nodes below, where the caverns taper at their upper limit, they will have a slightly different shape as the taper is now linear.
* Dungeons: Add Y limits in all mapgensparamat2018-02-20
| | | | Preserve the upper limit used in mgvalleys.
