2017-01-04Improve getPointedThing() (#4346)Dániel Juhász
* 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()).

2016-12-07Liquids: Update flow on block loadMillersMan
When loading a block add liquid-nodes that might flow away or spread to neighbours to the transforming_liquid queue.
2016-12-07Liquids: Preserve flow state if 'ignore' is a neighbourMillersMan
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.

2016-10-27Use node lighting for liquid spreadingDániel Juhász
This commit modifies the liquid transforming procedure to light and unlight nodes instead of whole map blocks.
2016-10-27Improved lightingDániel Juhász
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
2016-07-03Add MapSettingsManager and new mapgen setting script API functionskwolekr
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.
