* Remove unused functions reported by cppcheck (#10463)SmallJoker2020-10-05
| | | | | | | Run unused functions reported by cppcheck This change removes a few (but not all) unused functions. Some unused helper functions were not removed due to their complexity and potential of future use.

* Drop content_sao.{cpp,h}Loic Blot2020-04-11
| | | | | | | Move LuaEntitySAO to a new dedicated file Drop TestSAO (useless object) Drop the old static startup initialized SAO factory, which was pretty useless. This factory was using a std::map for 2 elements, now just use a simple condition owned by ServerEnvironment, which will be lightweight, that will also drop a one time useful test on each LuaEntitySAO creation. This should reduce server load on massive SAO creation

* Randomwalk cave liquids: Remove deprecated 'lava depth' parameter (#9105)Paramat2019-11-18
| | | | | | | | | Low-disruption first step towards removing the hardcoded cave liquid code. Since MT 5.0.0 cave liquids can be defined and located by biome definitions instead. In games that do not yet use biome definitions to define and locate cave liquids (MTGame does), lava will now appear below y = water_level - 256 instead of below 'lava depth' (usually y = -256). Therefore no change in most mapgens if using the default 'lava depth'.
* Tunnels: Completely disable generation when 'cave width' >= 10.0 (#9093)Paramat2019-11-09
| | | | | | | | | Previously, the only way to disable the 3D noise tunnels was to set 'cave width' > 1.0, however doing so did not disable the very intensive noise calculations or the generation loop. All the other types of cave generation (randomwalk caves, caverns) can already be independently and completely disabled. This feature is now needed more because the small randomwalk caves are now available for use as an alternative to the 3D noise tunnels.
* Randomwalk caves: Add parameters for number, proportion flooded. Allow small ↵Paramat2019-11-08
| | | | | | | | | | | | | | caves (#8928) Add mapgen parameters to set the range of the random number of randomwalk caves per mapchunk, and to set the proportion that are flooded with liquids. Default values are, for now, unchanged from the previous hardcoded values. Add parameters to allow small randomwalk caves Disabled by default for now as they have never been present in the non-mgv6 mapgens.
* Dungeons: Clean up parameters, improve structure variety (#8918)Paramat2019-09-14
| | | | | | | | | | | | | While preserving the general character of dungeon structure. Slightly increase the range of standard room horizontal size, while preserving the average horizontal size. Return to classic maximum large room size of 16x16x16. Make 1 in 4 dungeons have a 1 in 8 chance for each room being 'large', making multiple large rooms possible for the first time. Make 1 in 8 dungeons allow diagonal corridors, to make these a little more common. Make corridor width vary from 1 to 2, but forced to 2 if diagonal corridors are allowed, to make them passable. Add some comments.

* Better F6 profiler (#8750)SmallJoker2019-08-13
| | | | | | | Update the profiler names to make more sense of what they actually represent Move the profiler code from header to its source file Use monospace font to align lines Format the statistics line to align better with surrounding values Refresh the profiler each 3 seconds (roughly)
* Re-order mapgens in mainmenu and 'all settings' mapgen selection (#8705)Paramat2019-07-25
| | | | | | v6 always last to discourage selection. Special mapgens flat, fractal, singlenode, next to last. Of these, singlenode last to discourage selection. Of the remaining, v5 last due to age, v7 first due to being the default.
* Dungeons: Make multiple large rooms possible (#8678)Paramat2019-07-16
| | | | | | | | | Re-add the random size range for large rooms. Remove 'first_room_large' bool. Add 'large_room_chance' parameter that can disable large rooms, specify 1 large room, or specify a chance for large rooms. If 1 or a chance is specified, the first generated room is large, to take advantage of the intersection checks that are done for the 1st room only.
* Move more dungeon parameter selection to mapgens (#8653)Paramat2019-07-09
| | | | | | | | | | Move 'num_dungeons' to 'DungeonParams'. Add new parameter 'num_rooms' to replace 'rooms_min' and 'rooms_max', so that the mapgen has complete control over the number of rooms. Add new bool 'first_room_large' so that the mapgen chooses this instead of a hardcoded 1 in 4 chance. Add new parameter 'room_size_large' to replace 'room_size_large_min' and 'room_size_large_max', so that the mapgen has complete control over this.
* Dungeongen: Remove most hardcoded dungeon nodes (#8594)Paramat2019-06-30
| | | | | | | | | | | | | | | Biome-defined dungeon nodes was added as a feature to MT 5.0.0. So now remove most of the hardcoded dungeon node code that assumes a game has stone, sandstone, desert stone, and no other stone types. If biome-defined dungeon nodes are not found, dungeon nodes fall back to the 'cobble' mapgen alias if present, if not present they fall back to biome-defined 'stone'. Remove now-unnecessary mapgen aliases from MapgenBasic. Non-mgv6 games now only need to define 3 to 5 mapgen aliases. Document dungeon parameters. Make c_lava_source fallback to c_water_source as both are used as cave liquids.
* Dungeons: Settable density noise, move number calculation to mapgens (#8473)Paramat2019-06-01
| | | | | | | | | | | | Add user-settable noise parameters for dungeon density to each mapgen, except V6 which hardcodes this noise parameter. Move the calculation of number of dungeons generated in a mapchunk out of dungeongen.cpp and into mapgen code, to allow mapgens to generate any desired number of dungeons in a mapchunk, instead of being forced to have number of dungeons determined by a density noise. This is more flexible and allows mapgens to use dungeon generation to create custom structures, such as occasional mega-dungeons.

* mapgen: drop mapgen id from child mapgens.Loïc Blot2019-03-31
| | | | | | This id must be owned by the child mapgen and never be set to a misc value by a developer Also use nullptr in some places
* Biome API: Fix absent water decorations and dust, in deep water (#7470)Paramat2018-06-21
| | | | | | | | | | | | Previously, the biomemap was 'BIOME_NONE' for a mapchunk column if a stone surface was not found in it, causing water surface decorations and water surface dust to fail. Store the biome ID of the biome calculated at a water surface and add it to the biomemap if the biomemap is 'BIOME_NONE' for the mapchunk column. The biome calculated at a stone surface still has priority for the biomemap entry, as it should. Edit an incorrect comment.
* Biome dust: Revert fix that added dust to mod structures (#7464)Paramat2018-06-19
| | | | | | | | | Revert commit 99143f494711034068685b6ee845ce19fa09d7d9 and commit f4ca830abe1aa22875c99b31bf2ee56e26f83f05. These commits caused biome dust to be applied even when there was no core mapgen terrain in a mapchunk column. So the dust, which overgenerates, then appeared on structures added by mods in 'on_generated', such as floatlands, asteroids or above-surface realms.
* Mapgen flags: Add 'biomes' global mapgen flag (#7355)Paramat2018-06-08
| | | | | | | | | Previously the only way to disable biomes was to 'clear' the registered biomes in a mod, but this method causes large amounts of unnecessary processing: 1. Calculation of 4 2D noises. 2. Looping through all nodes of a mapchunk replacing nodes with identical nodes. The new flag disables those operations.

* Biomemap: Avoid empty biomemap entry to fix failing biome dust (#7393)Paramat2018-06-02
| | | | | | | | | | | | 'generateBiomes()' constructs the biomemap as it generates biomes. The biome calculated at first stone surface encountered is added to the biomemap. Previously, if no stone surface was encountered in a mapchunk column the biomemap was left empty for that (x, z) position, causing biome dust and water surface decoration placement to fail. If at the base of a mapchunk column the biomemap is empty, add the currently active biome to the biomemap, or if biome is NULL calculate it for this position and add it to the biomemap.

* Mapgen caves: Re-order generation to fix cavern bugParamat2018-04-29
| | | | | | | Previously, caverns confused tunnel generation causing biome top and filler nodes to appear in caverns. Split 'generateCaves()' into 2 functions to separate tunnel and large randomwalk cave generation. In each mapgen re-order cave generation to generate tunnels before caverns.

* Biome API / dungeons: Add biome-defined dungeon nodesParamat2018-04-07
| | | | | | | | | | Add new biome fields 'node_dungeon', 'node_dungeon_alt', 'node_dungeon_stair'. If 'node_dungeon' is not defined dungeons fall back to classic behaviour. Remove messy and imprecise dungeon material code from 'generateBiomes()'. Code deciding dungeon materials is now in 'generateDungeons()' and uses the biome at mapchunk centre for more precision. Remove hardcoded 'MG_STONE' types as long intended.
* Biome API / cavegen: Add definable cave liquid for a biome (#7192)Paramat2018-04-05

* Dungeons: Avoid generation in multiple liquid nodes and 'airlike'paramat2018-02-13
| | | | | | | | | | | | | | Previously only 'mapgen water source' and 'mapgen river water source' were checked for. Games can use multiple liquid nodes defined for biomes, many of which will not be aliased to those 2 mapgen aliases, causing floating dungeons to generate in some liquids. Now we check for liquid drawtype instead, so can remove liquid nodes from dungeonparams. Also check for 'airlike' drawtype instead of 'CONTENT_AIR' to avoid generation in 'airlike' nodes in some rare situations. This will also be needed for when we add definable biome air nodes.
