* Minimal: Add river water nodes (#5809)Paramat2017-05-24
| | | Is a base terrain node needed by any core mapgen with sloping rivers.
* Private nodemeta (#5702)sfan52017-05-10
| | | | * Private node metadata that isn't sent to the client
* Player attrs: permits to remove an attribute by setting value to nil (#5716)Loïc Blot2017-05-07
| | | | | | | | | | * Player attrs: permits to remove an attribute by setting value to nil When doing player:set_attribute("attr", nil) remove attribute Also remove a useless check on C++ API part (already done by checkplayer) Fix #5709
* Fix not being able to damage players in minimal (#5266)red-0012017-02-18

* Add 2D sheet animation for nodessfan52017-01-02
|
* Added "[sheet" to the texture special commands.Luke Puchner-Hardman2017-01-02
| | | | | | | | "[sheet:WxH:X,Y" assumes the base image is a tilesheet with W*H tiles on it and crops to the tile at position X,Y. Basically it works like "[verticalframe" but in 2D. For testing, I combined the four default_chest images into one.
* Mapgen: Various fixes and improvementsparamat2016-01-11
| | | | | | | | | | | | | 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

| | | | Fix 'is ground content' for some nodes
* Simpler patch for saplings trying to grow on unknown nodesShadowNinja2015-06-16
|
* Add list-ringsest312015-06-16
| | | | | | | Adds list-rings, a method to implement item sending between inventories via shift-click. Nice insider feature: a ring consisting of a single inventory list serves as nice clean-up method. Also adds them to minimal game, and the standard inventory. Craft output slots are not supported.
* Don't crash when saplings try to grow on unknown nodesy.st2015-06-15

* Fix NDT_GLASSLIKE normalsKahrl2015-01-31
| | | | Remove inventorycube() workaround for default:glass in minimal game
* Remove builtin_biome.lua from builtin and add simple biome minimalparamat2015-01-11
|
* Add minetest.swap_nodeNovatux2013-11-30
|
* Change default value of is_ground_content to truekwolekr2013-11-30
| | | | Most modders would otherwise forget to explicitly define this, and generated nodes aliased from mods would wall-off caves
* Fix possible crash with grass ABM.Novatux2013-11-02

* Add drowningPilzAdam2013-06-19
|
* Compress texturesDavid Gumberg2013-06-18
|
* Move scriptapi to separate folder (by sapier)sapier2013-05-25
| | | | | | | | | | | On the lua side, notably minetest.env:<function>(<args>) should now be replaced by minetest.<function>(<args>). The old way is and will stay supported for a long time. Also: Update and clean up lua_api.txt (by celeron55) Move EnvRef to lua and remove add_rat and add_firefly (by kahrl) Add separate src/util/CMakeLists.txt, other minor fixes (by kahrl)
