* Move debug.txt after it grows too big (#8904)HybridDog2019-09-07

* Re-order mapgens in mainmenu and 'all settings' mapgen selection (#8705)Paramat2019-07-25
| | | | | | v6 always last to discourage selection. Special mapgens flat, fractal, singlenode, next to last. Of these, singlenode last to discourage selection. Of the remaining, v5 last due to age, v7 first due to being the default.
* Mgfractal: Make non-fractal terrain optional (#8702)Paramat2019-07-25
| | | | | | Enabled by default. Only allow spawn on fractal, not on seabed terrain. Various codestyle and comment improvements.

|
* Mapgen Carpathian: Add optional rivers (#7977)Paramat2019-06-19
| | | | | Rivers are disabled by default and will not be added to existing worlds. Rewrite getSpawnLevelAtPoint() to be simpler and more consistent with generateTerrain().
* Use CDB author and name in installed package's config (#8550)Paul Ouellette2019-06-10
| | | | They are used for tracking the package, so should match ContentDB.
* Save forceloaded blocks file periodically (#8535)Thomas Rudin2019-06-10
| | | | | saves the forceloaded blocks periodically. checks every 10 seconds if the forceloaded blocks got changed in-game and persists them on-disk if that's the case
* Remove modstore leftovers. Fix core.show_path_select_dialog documentation ↵DS2019-06-07
| | | | | (#8572) This was forgotten in #5852.
* HTTP API: Allow binary downloads and headers (#8573)SmallJoker2019-06-06
| | | | Add minetest.features.httpfetch_binary_data
* Dungeons: Settable density noise, move number calculation to mapgens (#8473)Paramat2019-06-01
| | | | | | | | | | | | Add user-settable noise parameters for dungeon density to each mapgen, except V6 which hardcodes this noise parameter. Move the calculation of number of dungeons generated in a mapchunk out of dungeongen.cpp and into mapgen code, to allow mapgens to generate any desired number of dungeons in a mapchunk, instead of being forced to have number of dungeons determined by a density noise. This is more flexible and allows mapgens to use dungeon generation to create custom structures, such as occasional mega-dungeons.
* builtin/../register.lua: Abort make_wrap_deregistration if param is invalidANAND2019-05-04
|
* World start time: Move to first full light (day night ratio = 1000) (#8410)Paramat2019-04-13
| | | | | | | | 6125 is the time of first full light according to 'get_node_light()', and the time of first full light visually when basic shaders are on. This is the optimum default new world start time, taking all possible games into account. The previous time assumed a game similar to Minetest Game. Games should set this setting themselves according to their needs.
* Change pitch fly binding to 'P', add to change keys menu (#8314)rubenwardy2019-04-03
|
* Optimize core.after in a simple way (#8351)DS2019-03-27
|
* Require 'waving = 3' in a nodedef to apply the liquid waving shader (#8418)Paramat2019-03-27
| | | | | | | | Makes the liquid waving shader per-nodedef like waving leaves/plants, instead of being applied to all liquids. Like the waving leaves/plants shaders, the liquid waving shader can also be applied to meshes and nodeboxes. Derived from a PR by t0ny2.
* Document 'highly unstable' mapgens instead of 'stable' mapgens (#8404)Paramat2019-03-20

* num_emerge_threads: Fix documentation of automatic selectionparamat2019-03-17
