* g_extrusion_mesh_cache new() and grab() to be managed in constuctor only (#7235 partial)
This global was getting grab()-ed by each call to getItemMesh, incrementing its reference count. What was to be the final drop() in the destructor ended up with > 0 reference count, so memory not freed by Irrlicht.
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.
Split some long lines.
Edit comments.
Remove unnecessary comments and unnecessary commented-out code.
Use std::fmax/fmin instead of MYMAX/MYMIN.
Remove scope-limiting braces.
Consistently define literals as floats, except in noise parameters.
Cleanup literals in noise parameters.
Remove unnecessary 'near_cavern' line.
Reduce max spawn y to be consistent with other mapgens.
Caverns first appeared in mgvalleys and were later added to other
mapgens as shared code. Now this shared code can replace mgvalley's
internal cavern code.
Also use shared tunnel code instead of internal code.
Changes to mapgen that will affect existing worlds (mgvalleys is not
stable):
Single lava and water sources not added in tunnels.
Previous caverns are unchanged but an equal number of new ones are
added at a distance from the previous.
From y = -256 to 192 nodes below, where the caverns taper at their
upper limit, they will have a slightly different shape as the taper
is now linear.
Instead of calling g_settings->getBool("flag") multiple times
during each movement step, the current settings are cached
in a new player object member. Updated via registered callbacks.
* Android: Add zoom, minimap, and toggle chat button
Zoom button is put above jump button.
Minimap and toggle chat button are put in settings bar.
* Jump button is rotated down button
* Move three buttons on the right screen higher
Fix elusive 5 year old bug that caused mgvalleys large caves to be flat and
limited to mapchunk borders.
Error was fixed 2 years ago in 'CavesV6' but not in 'CavesRandomWalk'.
In the client, raise lower limit from 30 to 45 degrees, to avoid server
seeing this as a zoom and loading world beyond the server-set limit.
Add minimum in settingtypes.txt and enforce lower limit when set using
minetest.conf.
In the server, distrust the client-sent FOV if below the heuristic zoom
threshold and use the player object property 'zoom_fov' to check it, to
protect against hacked clients.
* Android: Replace movement buttons with joystick
Replace movement control buttons (arrows at bottom left screen) with virtual joystick.
Joystick has 8 directions (same as keyboard). Basically, just map it to keyboard input.
Joystick applies only on left 1/3 of screen.
Joystick's position can be fixed by enabling fixed_virtual_joystick setting.
Three new images:
(1) placeholder joystick,
(2) joystick container (background), and
(3) joystick cursor.
Remove unused images: movement control buttons (*_arrow.png).
New data type: touch_gui_joystick_move_id
Joystick's fixed position is spaced one button size from bottom and from left of screen.
Remove unused variable: m_joystick_downlocation
Fix for incorrect translation of empty strings
In the key change menu, when a button key not have name an empty string is passed to gettext.
The empty string is reserved for gettext to return de header of the .po file an this is shoved in the button
Commit 5070ca2111dd5b3f333a942059ef2c592de8dc24 changed sun colour by
fixing what seemed to be a code mistake.
Return to the standard colour but comment-out the first assignment of the
double-assignment for performance.
Add a comment to explain.
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.
* Promote performance-type-promotion-in-math-fn as a coding error
* Promote performance-faster-string-find too (which is not problematic currently)
* Same for performance-implicit-cast-in-loop
* Fix remaining tidy points
* src/sky.cpp 146 warn V519 The 'suncolor_f.r' variable is assigned values twice successively. Perhaps this is a mistake. Check lines: 142, 146.
* src/sky.cpp 147 warn V519 The 'suncolor_f.g' variable is assigned values twice successively. Perhaps this is a mistake. Check lines: 143, 147.
* src/sky.cpp 148 warn V519 The 'suncolor_f.b' variable is assigned values twice successively. Perhaps this is a mistake. Check lines: 144, 148.
* src/threading/thread.cpp 63 err V730 Not all members of a class are initialized inside the constructor. Consider inspecting: m_thread_obj.
* src/server.cpp 3243 err V595 The 'log' pointer was utilized before it was verified against nullptr. Check lines: 3243, 3258.
* Use constexpr + unroll some calculations to cache definitively some calculations
* Unroll some calls in collision code & use a constref instead of a copy in one occurence
* Fix many issues reported by clang-tidy
We have many issues in code related to some performance to float <-> double.
Clang-tidy reported it in performance-type-promotion-in-math-fn
I fixed many of them. It's not ready for a promote to blocking
Also fix some value which should be const-ref
* Implement new travis clang-tidy build step
* This step enable some rules and enforce one rule as error
* This permits to have some C++ quality rules based on clang & clang contributor guidelines
* Fix clang-tidy reported problems on push_back -> emplace_back
