kwolekr ebe638c32d Mapgen V6: Synchronize spflags with defaultsettings 
This fixes an issue where trees are omitted from Mapgen V6 maps on
configurations that explicitly defined the mgv6_spflags setting.
 2016-05-10 22:44:18 -04:00
paramat 4adbd69a37 FindSpawnPos: Let mapgens decide what spawn altitude is suitable 
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

paramat 8fc8cb819b Mapgen: Various fixes and improvements 
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

paramat 49073ba2c3 Mapgen: Add propagate_shadow bool to calcLighting 
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
 2015-12-07 03:18:24 +00:00
paramat d7bbe81726 Mapgen: Add global 'decorations' flag 
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
 2015-11-21 00:10:08 +00:00
paramat 4434498367 Mgv6: Move global mapgen flag 'flat' into mgv6 spflags 
Add mgv6 spflag 'flat'
Global flag is kept for backwards compatibility but is now undocumented
 2015-11-13 04:25:08 +00:00
paramat 7504cdcfbf Mapgen: Use mapgen-specific names for constants in headers 
Update copyright years in all mapgens
Add myself to copyright notices in mgv5 and mgv7

est31 452df1c723 Various style cleanups + unused code removal 
-> 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

kwolekr 7233a1228e Lighting: Fix nearly all issues 
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.

kwolekr 5a34f40d80 Huge overhaul of the entire MapgenParams system 
MapgenParams is no longer a polymorphic class, eliminating the need for messy and bug-prone reallocations.
Separation between the common and mapgen-specific parameters is now strongly defined.
Mapgen parameters objects are now properly encapsulated within the proper subsystems.
