* Light calculation: New bulk node lighting codeDániel Juhász2017-03-11
| | | | | | | | | | | This commit introduces a new bulk node lighting algorithm to minimize lighting bugs during l-system tree generation, schematic placement and non-mapgen-object lua voxelmanip light calculation. If the block above the changed area is not loaded, it gets loaded to avoid lighting bugs. Light is updated as soon as write_to_map is called on a voxel manipulator, therefore update_map does nothing.
* Voxelmanip: Do not emerge or blit to blocks over map gen limitparamat2017-02-18
| | | | | | | | | | | | | | | Placing a structure that extends into mapblocks that extend past map_gen_limit causes a crash. For example a sapling growing at the world edge which adds leaves beyond the edge, or placing a structure using the lua voxelmanip, or placing a schematic or l-system tree. Do not run the 'load_if_inexistent' block of code if the mapblock is over limit, this also marks the mapblock with the flag VMANIP_BLOCK_DATA_INEXIST which later prevents blitting back those mapblocks. This fix therefore uses existing functionality by having the same effect as the 'load_if_inexistent' bool being false.
* Lighting: Update lighting at block loadingDániel Juhász2017-02-13
| | | | | This commit updates mapblocks' light if necessary when they are loaded. This removes ghost lighting.
* Remove `mathconstants.h` and use the correct way to get `M_PI` in MSVC. (#5072)red-0012017-01-20

* Map generation limit: Fix checks for block/sector over-limitparamat2017-01-08
| | | | | | | | | | | | | | Fix the maths that check if any part of a mapblock or sector is over the set map_generation_limit. Therefore avoid the loading of any over-limit blocks that were previously generated when map_generation_limit was larger. The set limit can vary for a world because it is not yet a per-world mapgen parameter, even when it is sometimes it will be changed deliberately. Therefore avoid a player being returned to world centre if they re-enter a world while being over-limit. Fix the createSector() crash caused by a mob spawning over-limit in an over-limit mapblock
* Improve getPointedThing() (#4346)Dániel Juhász2017-01-04
| | | | | | | | | | | | | | | | | | | * Improved getPointedThing() The new algorithm checks every node exactly once. Now the point and normal vector of the collision is also returned in the PointedThing (currently they are not used outside of the function). Now the CNodeDefManager keeps the union of all possible nodeboxes, so the raycast won't miss any nodes. Also if there are only small nodeboxes, getPointedThing() is exceptionally fast. Also adds unit test for VoxelLineIterator. * Cleanup, code move This commit moves getPointedThing() and Client::getSelectedActiveObject() to ClientEnvironment. The map nodes now can decide which neighbors they are connecting to (MapNode::getNeighbors()).

* Liquids: Update flow on block loadMillersMan2016-12-07
| | | | | When loading a block add liquid-nodes that might flow away or spread to neighbours to the transforming_liquid queue.
* Liquids: Preserve flow state if 'ignore' is a neighbourMillersMan2016-12-07
| | | | | | | Prevent waterfalls from falling down or streams from flowing away when the source node is in an unloaded block - Nodes near a CONTENT_IGNORE node will be interpreted as if the ignored node is a liquid node that just supports the current state of the nodes in question.

* Use node lighting for liquid spreadingDániel Juhász2016-10-27
| | | | This commit modifies the liquid transforming procedure to light and unlight nodes instead of whole map blocks.
* Improved lightingDániel Juhász2016-10-27
| | | | | | | | | | | | | | This commit rewrites the procedure that is responsible for light updating. this commit -provides iterative solutions for unlighting and light spreading -introduces a new priority queue-like container for the iteration -creates per-node MapBlock caching to reduce retrieving MapBlocks from the map -calculates with map block positions and in-block relative node coordinates -skips light updating if it is not necessary since the node's new light will be the same as its old light was
* Add MapSettingsManager and new mapgen setting script API functionskwolekr2016-07-03
| | | | | | | | | | | | | | | 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.
