* Dungeongen: Fix selection of diagonal corridorsparamat2017-01-26
| | | | | | The do .. while loop is waiting for both dir.X and dir.Z to be non-zero, so should continue to loop if either dir.X or dir.Z are zero. The brackets present suggest this was intended to be OR not AND.
* Dungeongen: Fix out-of-voxelmanip access segfaultparamat2017-01-25
| | | | | | | | | | | My recent dungeon commit allowed stairs to be placed across the full width of corridors, but some of the new node positions accessed were missing checks for being within the voxelmanip, causing occasional segfaults near dungeons with corridors wider than 1 node. Add 'vm->m_area.contains(pos)' checks just before stair position voxelmanip access. This allows an earlier check to be removed as it is now redundant.
* Dungeons: Support nodebox stairs wider than 1 nodeparamat2017-01-23
| | | | | | | Previously, code did not support stair nodeboxes in corridors wider than 1 node. Make stair nodeboxes full width even in corridors with different widths in X and Z directions.
* Dungeons: Generalise use, add capabilities, various modificationsparamat2016-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Generalise node names to c_wall and c_alt_wall - Remove 'mossratio' and instead disable alt_wall loop if c_alt_wall == CONTENT_IGNORE - Use one generalised 3D noise for alternative wall nodes and in mgv6 create moss distribution similar to the previous - Rename rarity noise to density noise and enable the option of multiple dungeons per chunk determined by the value. Recreate previous distribution - Add parameters for min and max rooms per dungeon - Add dungeon y limits - Integrate river water properly Generalisation is needed now that we have sandstone and desert stone dungeons by default and can choose any node for alternative structure. The current code is based around cobble dungeons with mossycobble alternative nodes, the 2 noises controlling the alternative nodes are based on wetness. Enabling multiple dungeons per chunk with definable number of rooms allows the option of very dense and complex underground structures that could interconnect to create megastructures. Y limits are added to be consistent with other mapgen elements, and enable locaton of dungeon or megastructure realms as part of our 'stacked realms' philosophy.

* Fix undefined evaluation order when constructing random vectorskwolekr2016-05-27
| | | | | | | | | | | | | | MSVC and GCC evaluate parameters in right-to-left order, whereas Clang evaluates in left-to-right order, and of course, an optimization could leave the order of evaluation completely indeterminate. This commit fixes all instances of the error by explicitly assigning the results of expressions that use PseudoRandom::next() or range() to their respective vector components. The right-to-left evaluation behavior is preserved since Clang is much less commonly used to compile Minetest than GCC and MSVC combined, and would therefore cause the least harm.

* 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
* Dungeongen: Fix rarely triggered segfaultparamat2015-12-01
| | | | | | | A segfault exposed a missing 'vm->m_area.contains()' check in makeCorridor that allowed the calculation of vm index for a node outside the vm area. The huge and invalid index number caused getContent to fail
* Dungeongen: Also preserve river water nodesparamat2015-11-29
| | | | | | For future river mapgens Dungeons will not generate in river water, to avoid dungeons filling and blocking river channels
* Dungeongen: Remove floating framesparamat2015-08-29
| | | | | | | | Preserves the rare unbroken protruding dungeons Fix random range for first room roomplace Fix checked volume for first room 'fits' bool and check for 'untouchable' flag instead of 'inside' Remove 'enable floating dungeons' setting

* Huge overhaul of the entire MapgenParams systemkwolekr2014-02-03
| | | | | | 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.
