* Mgv7: Combine mountain terrain generation with base terrain generationparamat2016-04-20
| | | | | | | | | | | | Previous mountain terrain generation was by necessity placing stone in air, this was removing air from any overgenerated structures such as tunnels, dungeons and large caves Moving it into the base terrain generation loop ensures that only 'ignore' is replaced generateRidgeTerrain: only return if node_max.Y < water_level - 16 Previously, if water level was set a few nodes above a mapchunk border the river channel was only partially excavated
* Mgv7, mgflat, mgfractal: Tunnel generation code optimisationparamat2016-04-12
|
* Mapgen: Optimise cave noises and tunnel excavationparamat2016-04-08
| | | | | | Instead of doing nothing at node_max.Y + 1 use 1-down overgeneration for tunnel generation and noisemaps Move some old unused code in mgv7 to end of file
* Mgv7: Decrease cliff steepnessparamat2016-03-30
|
* Mgv7/flat/fractal: Stop tunnel-floor biome nodes being placed everywhereparamat2016-03-21
| | | | | | A bool for 'in or under tunnel' was missing 1-node-deep stone ledges were being replaced with biome surface material
* Mgv7: Limit pseudorandom caves to surface mapchunk or belowparamat2016-03-19
| | | | To avoid bright caves at mapchunk borders when generating mapchunks upwards
* Mapgen: Fix light in tunnels at mapchunk bordersparamat2016-03-14
| | | | | | Don't excavate the overgenerated stone at node_max.Y + 1, this creates a 'roof' over the tunnel, preventing light in tunnels at mapchunk borders when generating mapchunks upwards.
* 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
* Mgv5/v7/flat/fractal: Move tunnel noise calculation into generateCavesparamat2016-02-02
| | | | | | | | | | Tunnel 3D noises are only calculated when solid terrain is present in mapchunk, avoiding large amounts of unnecessary calculations Change 'int' to 's16' in calculateNoise Change 'i' to 'vi' for voxelmanip indexes for consistency Keep 'u32 index3d' local to a smaller part of tunnel code Mgv7: Don't call CaveV7 if no solid terrain in mapchunk Give 'open' bool a more descriptive name

* 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.
