* Mgv6 mudflow: Remove decoration if 'dirt with grass' below flows away (#5798)Paramat2017-05-25
| | | | | | | Mudflow of a neighbouring mapchunk extends into a mapchunk's edge, and could remove 'dirt with grass' from under a decoration, creating unsupported decorations. Remove any decoration above if a 'dirt with grass' node is removed by mudflow.
* Dungeongen: Add and improve parametersparamat2017-02-26
| | | | | | | | | | | | | | | | | | Add: Bool for 'only_in_ground'. Min and max corridor length. Min and max room size with X, Y, Z components. Min and max large room size with X, Y, Z components. 'only_in_ground = false' allows core mapgens to create structures in air and water using dungeongen. Corridor length parameters replace a fixed random range. Room size parameters replace the former system where one parameter 'roomsize' was added to fixed random ranges. All parameters are set for no change to current dungeon behaviour. Remove some now-redundant and long-unused code.
* Mgv6: Add fallback node for gravelparamat2017-02-04
| | | | | | | | Gravel now falls back to stone. Gravel is not a particularly fundamental node, allowing it to fall back to stone frees up subgames from having to include a gravel node. Non-blob-ore gravel is only present in mgv6 as extremely rare 'gravel biomes'.
* Mgv6: Add stairs to desert stone dungeonsparamat2017-02-04
| | | | | | As with the other mapgens, now that wide stairs in dungeons are possible we can now finally add stairs to desert stone dungeons. Re-order some lines.
* Mapgen: Remove unused 'flat' and 'trees' flags from mg_flagsparamat2016-08-04
| | | | | | | | | | | | | | | | When the 'flat' and 'trees' flags were moved into mgv6_spflags they were left in mg_flags in an attempt to support old mgv6 worlds. However their appearence in mg_flags causes confusion, also, later, old-world support was found to be broken for mgv6 worlds with 'notrees'. This commit cleans up the mess and comes a month after a thread warning of the change, and explaining the required action, was posted in the news subforum. Only old mgv6 worlds with 'flat' or 'notrees' are affected, a small minority of worlds, the required action being correctly setting these flags in mgv6_spflags. Disable a section of the 'map settings manager' unit test which is to be changed as it is causing problems for pull requests.
* 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.
* Dungeons: Generalise use, add capabilities, various modificationsparamat2016-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Generalise node names to c_wall and c_alt_wall - Remove 'mossratio' and instead disable alt_wall loop if c_alt_wall == CONTENT_IGNORE - Use one generalised 3D noise for alternative wall nodes and in mgv6 create moss distribution similar to the previous - Rename rarity noise to density noise and enable the option of multiple dungeons per chunk determined by the value. Recreate previous distribution - Add parameters for min and max rooms per dungeon - Add dungeon y limits - Integrate river water properly Generalisation is needed now that we have sandstone and desert stone dungeons by default and can choose any node for alternative structure. The current code is based around cobble dungeons with mossycobble alternative nodes, the 2 noises controlling the alternative nodes are based on wetness. Enabling multiple dungeons per chunk with definable number of rooms allows the option of very dense and complex underground structures that could interconnect to create megastructures. Y limits are added to be consistent with other mapgen elements, and enable locaton of dungeon or megastructure realms as part of our 'stacked realms' philosophy.

* Cavegen: Rename CaveV6 to CavesV6kwolekr2016-05-27
| | | | | | | - Add comment explaining why it exists - Remove unused 'flooded' variable - Rename shadowed variable - Fix some code style
* Mapgen V6: Synchronize spflags with defaultsettingskwolekr2016-05-10
| | | | | This fixes an issue where trees are omitted from Mapgen V6 maps on configurations that explicitly defined the mgv6_spflags setting.
* 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
* Mapgen: Various fixes and improvementsparamat2016-01-11
| | | | | | | | | | | | | Lua_api.txt: Document 'minetest.registered_biomes' Minimal: Remove 'mapgen_air' alias Cavegen: Add fallback node for 'mapgen_ice' Dungeongen: Add fallback node for 'mapgen_river_water_source' Mgv5: Remove unnecessary '#include util/directiontables.h' Add missing 'this->'s in makeChunk() Mgv6: Edit empty line formatting Remove leading spaces in makeChunk() Add missing spaces after 'for' and 'if' Mgv7: Edit empty line formatting
* Mapgen: Add propagate_shadow bool to calcLightingparamat2015-12-07
| | | | | | | | | | To terminate unwanted shadows from floatlands or realms above Also add to LuaVoxelManip calc_lighting for use in mapgen mods Remove the 2 argument calcLighting, mapgens now use the 5 argument form to specify the volumes for propagateSunlight and spreadLight In mgsinglenode replace calcLighting with setLighting and clean-up use of tabs and spaces
* Mapgen: Add global 'decorations' flagparamat2015-11-21
| | | | | | | | | | Flag is set by default in MapgenParams The global 'trees' flag remains but is now undocumented and unset by default in MapgenParams Add mgv6_spflag 'trees' set by default in defaultsettings.cpp to affect new worlds only This is automatically backwards compatible for existing worlds

* Lighting: Fix nearly all issueskwolekr2015-01-04
| | | | | | | | | | | The cause of a single light source seemingly being lit without spread was due to its creation in the +Y mapblock boundary layer during map generation, which was ignored as the overtop. This overtop explicitly needs to be omitted during sunlight propagation, however. To accomplish this, Mapgen::calcLighting() was split into separate functions taking separate parameters. Additionally, do not diminish light too early during spread. This fixes the output inconsistency between Map::updateLighting and Mapgen::calcLighting.
