2017-10-29Biome API: Add decoration flags for underground decorationsparamat
Add "all_floors" and "all_ceilings" flags for simple and schematic decorations. Decorations are placed on all floor and/or ceiling surfaces. Decorations are placed before dungeon generation so placement in dungeons is not possible. Add 'getSurfaces()' function to mapgen.cpp that returns 2 arrays of y coordinates for all floor and ceiling surfaces in a specified node column. Move 'getHeight()' checks into DecoSimple and DecoSchematic. Delete 'getHeight()' functions.
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.
2017-09-17Biome generation: Fix layers of 'filler' nodes at biome y limitsparamat
Error was exposed by commit a1389c38658fe69c3bd25c3099bae9a4e51ed401 'nplaced' was not set to U16_MAX when biome 'stone' was placed, so when biome was recalculated in a column of stone, the 'nplaced' value caused a few remaining filler nodes to be placed. Occurs when the lower biome has a deeper depth of 'top' plus 'filler' than the upper biome.
2017-09-16Generate biomes: Recalculate biome at biome lower limitparamat
Prevents biome nodes passing below the defined y_min of that biome.
2017-08-19Code modernization: src/m* (part 2)Loic Blot
* empty function * default constructor/destructor * remove unused Map::emergeSector(a,b) * for range-based loops * migrate a dirs[7] table to direction tables * remove various old unused function
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
2017-07-11Biomes/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.
2017-07-06Mapgen: Add Carpathian mapgen (#6015)Vaughan Lapsley
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.
2017-06-17Cpp11 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
2017-06-11(Re)spawn players within 'mapgen_limit'paramat
Previously, findSpawnPos() did not take the 'mapgen_limit' setting into account, a small limit often resulted in a spawn out in the void. Use the recently added 'calcMapgenEdges()' to get max spawn range through a new mapgenParams function 'getSpawnRangeMax()'. Previously, when a player respawned into a world, 'objectpos_over_limit()' was used as a check, which was inaccurate. Use the recently added 'saoPosOverLimit()' to get exact mapgen edges. Also fix default value of 'm_sao_limit_min'.
2017-06-03Properly remove SAO when worldedges are overtaken (#5889)Loïc Blot
* LuaEntitySAO: Remove beyond outermost mapchunk edges Based on a commit by, and with help from, nerzhul. Add 2 functions to class Mapgen: A function to calculate actual mapgen edges, called from the Mapgen constructor. A function called indirectly from content_sao.cpp per entity step to check SAO position is within mapgen edges. * Calculate borders from params not mapgen, which is not available everytime
2017-06-01Show singlenode mapgen to menu (#5868)Loïc Blot
Fix #5867
2017-05-26Mapgen files: Update and correct copyright creditsparamat
2017-04-04MapgenBasic: Add lava source as commonly used content (#5512)Paramat
Future mapgens are likely to use this for magma and volcanos. Remove the getting of lava source content id in mgvalleys.
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.
2017-04-01mapgen: Fix segfault when selecting invalid mapgen (#5491)SmallJoker
2017-03-27Map generation limit: Make per-worldparamat
The setting limits map generation but affects nothing else. Add 'mapgen_limit' to global mapgen parameters. Move 'blockpos_over_mapgen_limit()' to the only place it is called from: map.cpp. Allow teleportation to any part of the world even if over the set mapgen limit. Simplify the reading of this limit in mgvalleys. Remove the 'map_generation_limit' setting.
2017-03-05Dungeons: Use 'block' instead of 'brick' for nodebox stairsparamat
Affects only sandstone dungeons. Nodebox stairs made from 'sandstone_block' look better because every step is undivided.
2017-02-26Dungeongen: Add and improve parametersparamat
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.
2017-02-04MapgenBasic node resolver: Various fixesparamat
Add a fallback node for stair_desert_stone to avoid ignore placed in Minimal subgame desert dungeons. Don't allow river_water_source to fallback to water_source as river water needs to be non-renewable and have a short flow range. Make stair_sandstonebrick fall back to sandstonebrick instead of sandstone. Re-order some lines. Add a comment.
2017-01-26Dungeons: Add nodebox stairs to desert and sandstone dungeonsparamat
Desert and sandstone dungeons have 2 node wide corridors. Previously, nodebox stairs were disabled because dungeon generation code did not support nodebox stairs wider than 1 node, now it does. Add 'stair desert stone' content id to MappgenBasic. Requires 'mapgen stair desert stone' to be added to Minetest Game.
2016-08-04Mapgen: Remove unused 'flat' and 'trees' flags from mg_flagsparamat
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.
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.
2016-07-03Mapgen: Refactor mapgen creation and managementkwolekr
- Move mapgen creation logic out of EmergeManager and into Mapgen - Internally represent mapgen type as an enum value, instead of a string - Remove the need for a MapgenFactory per mapgen
2016-06-17Dungeons: Generalise use, add capabilities, various modificationsparamat
- 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.
2016-06-05Mapgen: Optimize biomemap creation by combining with generateBiomeskwolekr
2016-06-05Biome API: Add per-biome riverbed material and depthparamat
Mgvalleys: Remove riverbed sand placement from base terrain generation Riverbed material placement moved to MapgenBasic::generateBiomes() Document fields and add note that the biome API is still unstable
2016-06-04Mapgen: Performance improvement and fixes for updateLiquid (#4065)MillersMan
- Adds only ~100 nodes per chunk to trans_liquid with similar processing time - Adds liquid nodes themselves instead of potential solid nodes below them - CONTENT_IGNORE nodes are interpreted as if they continue their neighborhood - This allows liquid columns to span multiple chunks without being interrupted - NOTE: Expects an one-node border in generation chunk without liquid changes
2016-06-04Change internal type for seeds to s32kwolekr
This fixes value truncation (and therefore incompatibility) on platforms with an LP32 data model, such as VAX or MS-DOS.
2016-05-27Dungeongen: Remove dependency on Mapgenkwolekr
2016-05-27Mapgen: Combine dungeon generation codekwolekr
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.
2016-05-27Cavegen: Move V5-style caves to CavesNoiseIntersectionkwolekr
2016-05-27Cavegen: Re-add small caves to CavesRandomWalkkwolekr
2016-05-27Cavegen: Remove CavesRandomWalk dependency on Mapgenkwolekr
2016-05-27Cavegen: Merge CaveV5 and CaveV7 into CavesRandomWalkkwolekr
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.
2016-03-30Mapgen: Don't spread light of nodes outside the desired areakwolekr
This fixes #3935, a regression from 0338c2e. An 'optimization' was performed where an index for the VoxelManip being operated on was mistakenly used for bounds checking within the incorrect VoxelArea, namely, the area wherein light should be spread.
2016-03-29Mapgen: Spread both night and day light banks in spreadLightkwolekr
2015-12-07Mapgen: Add propagate_shadow bool to calcLightingparamat
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
2015-11-21Mapgen: Add global 'decorations' flagparamat
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
2015-10-23Decoration API: Add flag for placement on liquid surfaceparamat
Add findLiquidSurface() function to mapgen.cpp Update lua_api.txt
