* 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.
* 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()).
* 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.

* Add DISABLE_CLASS_COPY macro (and use it)kwolekr2015-10-27
| | | | | | | | | Use this macro to disallow copying of an object using the assignment operator or copy constructor. This catches otherwise silent-but-deadly mistakes such as "ServerMap map = env->getMap();" at compile time. If so desired, it is still possible to copy a class, but it now requires an explicit call to memcpy or std::copy.

| | | | | | 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.

* Set of changes to build mineTest using Visual Studio 11.0. These affectMukul Sati2013-03-24
| | | | | | | | | | | | | the following: 1. String concatenation in guiMainMenu.cpp - it is required for all individual strings to be of the same type <unicode/non-unicode>; adding explicit L qualifier before the other strings. 2. Correcting type of BlockMakeData to struct in place of class forward declarations. This information is used for name decoration by Visual Studio, leading to linker errors in case of mismatches. 3. Windows headers define max as a macro somewhere, leading to a compile time error in profiler.h; using () around function to prevent macro match from occurring.
