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.
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.
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.
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.
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.
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.
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.
- 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
- 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.
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
- 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
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.
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.
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.
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
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
-> Don't pass pointer to whole IGameDef to NodeMetadata constructors
and deserializers, but only to IItemDefManager, which is needed
-> Remove the unused content_mapnode_get_new_name() method
-> Fix style for MapBlock::deSerialize and MapBlock::deSerialize_pre22,
improving accuracy of error messages a bit
-> Fix style at other serialisation methods too
-> Improve accuracy of some comments
Move debug streams to log.cpp|h
