* FindSpawnPos: Let mapgens decide what spawn altitude is suitableparamat2016-02-09
| | | | | | | | | | | | To avoid spawn search failing in new specialised mapgens Increase spawn search range to 4000 nodes Add getSpawnLevelAtPoint() functions to EmergeManager, class Mapgen and all mapgens Remove getGroundLevelAtPoint() functions from all mapgens except mgv6 (possibly to be re-added later in the correct form to return actual ground level) Make mgvalleys flag names consistent with other mapgens Remove now unused 'vertical spawn range' setting

* Mgvalleys: fix riverbeds below sea levelDuane Robertson2016-02-02

* Mgv5/v7/flat/fractal: Move tunnel noise calculation into generateCavesparamat2016-02-02
| | | | | | | | | | Tunnel 3D noises are only calculated when solid terrain is present in mapchunk, avoiding large amounts of unnecessary calculations Change 'int' to 's16' in calculateNoise Change 'i' to 'vi' for voxelmanip indexes for consistency Keep 'u32 index3d' local to a smaller part of tunnel code Mgv7: Don't call CaveV7 if no solid terrain in mapchunk Give 'open' bool a more descriptive name
* Mgvalleys: use standard cavesDuane Robertson2016-01-31
| | | | | | | | | | Replace simple caves with V5 caves, adding unpredictable water and lava settings and massive caves based on subterrain. Remove fast terrain mode and accompanying settings. Remove superfluous temperature/humidity settings. Remove lava/water height setting. Fix errors in humidity handling and remove humidity_break_point setting. Move cave noises to generateCaves. Fix minor formatting/naming issues and use MYMAX/MYMIN/myround.

* Don't pass non-const references to collision methodsest312016-01-29
| | | | | Non const references cause a lot of confusion with behaviour of code, and are disallowed by minetest style guide.
* Clocksource: use a better clock if available.Auke Kok2016-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | clock_gettime() is a far better clock than gettimeofday(). Even better than clock_gettime() is that you can select either CLOCK_MONOTONIC, or even CLOCK_MONOTONIC_RAW. These clocks offer high precision time. And the _RAW variant will never roll back due to NTP drift or daylight savings, or otherwise. I've adjusted this code to select the right clock method auto- matically based on what's available in the OS. This means that if you're running a very old linux version, MacOS or other, you will automatically get the best clocksource available. I've tested all Linux clocksources by selectively compiling and running a 10k+ timer test suite. In all cases I confirmed that the 3 POSIX Linux clocksources worked properly, and were selected properly. I've modified the OS X compile path to use the high-res clock source for all time functions, but I can't confirm it works or that it compiles. As for WIN32, I confirmed that the used clocksource is indeed a Monotonic clocksource, so good news: that code section appears to be exactly what it should be.
* Don't print whole json data buffer to errorstream on errorest312016-01-28
| | | | | | `errorstream` must not be overly verbose as clientside it is directly printed onto the ingame chat window. These days, the serverlist can contain > 200k bytes, so better print it to warningstream if the data buffer is too long.
* Backface culling: Ignore setting in tiledef from old servers.Auke Kok2016-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | Outdated servers are always sending tiledefs with culling enabled no matter what, as the value was previously entirely ignored. To compensate, we must (1) detect that we're running against an old server with a new client, and (2) disable culling for mesh, plantlike, firelike and liquid draw types no matter what the server is telling us. In order to achieve this, we need to bump the protocol version since we cannot rely on the tiledef version, and test for it being older. I've bumped the protocol version, although that should have likely happened in the actual change that introduced the new backface_culling PR #3578. Fortunately that's only 2 commits back at this point. We also explicitly test for the drawtype to assure we are not changing the culling value for other nodes, where it should remain enabled. This was tested against various pub servers, including 0.4.13 and 0.4.12. Fixes #3598

* Allow per-tiles culling.Auke Kok2016-01-20
| | | | | | | | | | | | | | | | | | | | | | | | Backface culling is enabled by default for all tiles, as this is how the lua parser initializes each tiledef. We revert to always using the value from the tiledef since it is always read and serialized. Mods that wish to enable culling for e.g. mesh nodes, now can specify the following to enable backface culling: tiles = {{ name = "tex.png", backface_culling = true }}, Note the double '{' and use of 'name' key here! In the same fashion, backface_culling can be disabled for any node now. I've tested this against the new door models and this properly allows me to disable culling per node. I've also tested this against my crops mod which uses mesh nodes where culling needs to be disabled, and tested also with plantlike drawtype nodes where we want this to continue to be disabled. No default setting has changed. The defaults are just migrated from nodedef.cpp to c_content.cpp.

* Make all mesh manipulators in mesh.cpp work with any vertex typeKahrl2016-01-15
| | | | | | | | | cloneMesh() has to use a switch in order to create a different mesh buffer type depending on vertex type. (Credit: the new cloneMesh was written by RealBadAngel.) To avoid repetitive code, all other methods use getVertexPitchFromType() to automatically adapt the indexing to the vertex type at runtime.

* New 3D Mode: PageflipDalai Felinto2016-01-09
| | | | | | | | | | | | | | | | The pageflip mode requires a stereo quadbuffer, and a modern graphic card. Patch tested with NVidia 3D Vision. The mini-map is not drawn, but that's what is done for topbottom and sidebyside modes as well. Also most of the time the user would prefer the HUD to be off. That's for the user to decide though, and toggle it manually. Finally, the interocular distance (aka eye separation) is twice as much as the "3d_paralax_strength" settings. I find this a strange design decision. I didn't want to chance this though, since it's how the other 3d modes interpret this settings.

* filesys: safeWriteToFile(): Remove the target file before rename only on WindowsPerttu Ahola2016-01-01
| | | | | | | | | | Removing the target file on other platforms was enabled likely unintentionally by commit 5f1f1151d3a9c113902630adc16cc3f4845da7ba. This may be the reason why there has been corruption of files on Linux on hard shutdowns. Previously I described the problem and this fix in issue #3084.

* Fix cache path with RUN_IN_PLACEShadowNinja2015-12-30
| | | | | | | If an `XDG_CACHE_HOME` can't be found or `RUN_IN_PLACE` is enabled, `path_cache` is left at its default of `$PATH_USER/cache` (at a time when `PATH_USER` is `..`), rather than being reset to `$PATH_USER/cache` after `PATH_USER` has been properly set.
