* SAO limits: Allow SAOs to exist outside the set 'mapgen limit'paramat2018-06-03

* Properly remove SAO when worldedges are overtaken (#5889)Loïc Blot2017-06-03
| | | | | | | | | | | | * LuaEntitySAO: Remove beyond outermost mapchunk edges Based on a commit by, and with help from, nerzhul. Add 2 functions to class Mapgen: A function to calculate actual mapgen edges, called from the Mapgen constructor. A function called indirectly from content_sao.cpp per entity step to check SAO position is within mapgen edges. * Calculate borders from params not mapgen, which is not available everytime
* Time: Change old `u32` timestamps to 64-bit (#5818)SmallJoker2017-05-26

* Player data to Database (#5475)Loïc Blot2017-04-23

* Add on_flood() callback.Auke Kok2017-04-22
| | | | | | | | | | | | | | | | | | | | | This callback is called if a liquid definitely floods a non-air node on the map. The callback arguments are (pos, oldnode, newnode) and can return a `bool` value indicating whether flooding the node should be cancelled (`return true` will prevent the node from flooding). Documentation is added, the callback function was tested with a modified minetest_game. Note that `return true` will likely cause the node's `on_flood()` callback to be called every second until the node gets removed, so care must be taken to prevent many callbacks from using this return value. The current default liquid update interval is 1.0 seconds, which isn't unmanageable. The larger aim of this patch is to remove the lava cooling ABM, which is a significant cost to idle servers that have lava on their map. This callback will be much more efficient.
* Light update for map blocksDániel Juhász2017-04-20
| | | | | | | | | This is not really different from the light update of a voxel manipulator. This update does not assume that the lighting was correct before, therefore it is useful for correction. Also expose this function to the Lua API for light correction, and allow voxel manipulators not to update the light.

* Map generation limit: Make per-worldparamat2017-03-27
| | | | | | | | | | | The setting limits map generation but affects nothing else. Add 'mapgen_limit' to global mapgen parameters. Move 'blockpos_over_mapgen_limit()' to the only place it is called from: map.cpp. Allow teleportation to any part of the world even if over the set mapgen limit. Simplify the reading of this limit in mgvalleys. Remove the 'map_generation_limit' setting.

* 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.
