We try to use default fallback for both mono and main font when custom font path is not exist. This way, if Minetest is not corrupted, we could avoid crash.
Add "all_floors" and "all_ceilings" flags for simple and schematic
decorations. Decorations are placed on all floor and/or ceiling surfaces.
Decorations are placed before dungeon generation so placement in dungeons
is not possible.
Add 'getSurfaces()' function to mapgen.cpp that returns 2 arrays of y
coordinates for all floor and ceiling surfaces in a specified node column.
Move 'getHeight()' checks into DecoSimple and DecoSchematic. Delete
'getHeight()' functions.
This causes blocks in front of the player to be rendered sooner and
blocks in the periphal view (that would soon be out of view) a bit later.
Overall this leads to smoother rendering as the player is moving around.
Formspec input for each individual noise parameter and flag.
Allow noise flags to be set in advanced settings, previously only settable
in minetest.conf.
Standardise 'group format' for noise parameters set in minetest.conf, as
only these support noise flags. However the older 'single line' format is
still accepted to support existing minetest.conf files.
Therefore auto-generate minetest.conf.example with noise parameters in
'group format'.
Setting 'type' in settingtypes.txt is now either 'noise_params_2D' or
'noise_params_3D', the dimension number is displayed in the advanced
settings edit page.
This helps retrieving the right set of blocks when the player is falling,
traveling on cart, or in general traveling in a direction different from
the view direction.
Necessary for placing the base cube of 'plantlike_rooted' drawtype in the
seabed instead of on it.
Useful for placing decorations sunk into, or buried in, the ground.
For solid nodes, the lighting at a corner becomes face-dependent, which
means that only the four nodes in face-direction contribute to the
lighting (getSmoothLightSolid).
For special nodes, which use the lighting values at the eight corners of
a node, the lighting is not face-dependent, but certain nodes of the
eight surrounding nodes of a corner (here indices 4, 5, 6 and 7) can be
obstructed.
Ambient occlusion now also occurs for solid nodes, if two, three or four
of the four nodes in face-direction are solid.
In some cases NetworkPacket was created using default constructor and m_data is not properly sized.
This fixed out of bounds memory copy
Also use memcpy instead of std::vector affectation to enhance packet creation
If 'param2_max' is not used, parameter 'param2' works as before for
compatibility.
If 'param2_max' is used, 'param2' and 'param2_max' become the lower
and upper bounds of a per-decoration random param2.
Increase scrollrate depending on fontsize
Scroll on mousewheel
Allow scrolling and marking text on non writable textareas
Update lua api about readonly mode
Show scrollbar if text overflows
If either of the 2 noise parameters are omitted the ore will occur from y_min
to y_max in a simple horizontal stratum. As this does not compute noise
performance improves, and is ideal for placing many layers.
Clean up some nearby ore documentation.
* Make Player::peer_id server-side only and add getters and setters
Player::peer_id has no sense client side, move it to server, make it private and add setter and getter
Also add some PEER_ID_INEXISTENT instead of harcoded 0
* Add no_static_save property to luaentites to not save them statically.
This allows for temporary objects that would get deleted anyway as soon as they are loaded again without the static saving overhead.
* Use positive meaning for static_save object property
* Invert meaning also for the LUA parameter
Note: getboolfield() does not change &result when field does not exist, so it defaults to the default value in the header file, which is 'true'.
* Extend push_object_properties()
* Add session_t typedef + remove unused functions
u16 peer_id is used everywhere, to be more consistent and permit some evolutions on this type in the future (i'm working on a PoC), uniformize u16 peer_id to SessionId peer_id
* Update JsonCPP to 1.8.3
* Fix deprecated functions
Json::FastWriter, Json::StyledWriter and Json::Reader are marked deprecated since 1.1 and are deprecated in 0.8 but not shown at compilation time.
Use new methods to serialize/deserialize
Implement network communication for channels
* Implement ModChannel manager server side to route incoming messages from clients to other clients
* Add signal handler switch on client & ModChannelMgr on client to handle channels
* Add Lua API bindings + client packet sending + unittests
* Implement server message sending
* Add callback from received message handler to Lua API using registration method
Change OpenAL distance model from AL_INVERSE_DISTANCE to
AL_INVERSE_DISTANCE_CLAMPED to avoid excessive volume when very close
to the sound location, for example MTG doors, and MTG fire sounds which
are combined at an average position and often located in air nodes.
Because AL_REFERENCE_DISTANCE has been reduced to 1 node (the distance
under which gain is clamped), multiply volume by the same factor to keep
sound gains the same as before, since the gain is calculated as:
gain = (AL_REFERENCE_DISTANCE / distance)
Feature is unnecessary and would greatly complicate future development,
it would also make 'get biome at pos' extremely complex.
Mgv7: Revert option to repeat surface biomes in floatlands, which
depended on the above.
Error was exposed by commit a1389c38658fe69c3bd25c3099bae9a4e51ed401
'nplaced' was not set to U16_MAX when biome 'stone' was placed, so when
biome was recalculated in a column of stone, the 'nplaced' value
caused a few remaining filler nodes to be placed.
Occurs when the lower biome has a deeper depth of 'top' plus 'filler'
than the upper biome.
For 3D noise tunnels only, replace unsupported biome 'top' and 'filler'
nodes in tunnel roof with the defined biome 'stone'.
This makes terrain created by 3D noise tunnels consistent with the rest
of mapgen, which does exactly the same in this situation.
The 'glow' value is added to the ambient light value.
Negative 'glow' disables light's effect on object colour, for faking
self-lighting, UI-style entities, or programmatic colouring in mods.
Dig prediction allows clients to remove dug nodes without
waiting for server acknowledgement.
This patch allows mods to override dig prediction,
it can either be turned off or a different "prediction node"
can be selected.
For precise control of schematic vertical position relative to the
'place_on' node.
Avoids workarounds that add empty nodes to a schematic and therefore
reduce performance.
Also remove long-unused decoration cutoff code.
* Implement minetest.register_on_userlimit_check
This new callback permits to bypass the max_users parameter with new mods condition, based on player name or IP
Only one mod needs to permit it.
Move core part for builtin privileges checks to builtin
Creates a single undulating ore stratum that is continuous across mapchunk
borders and horizontally spans the world.
Due to being continuous is ideal for creating bands of alternative stone
type running through cliffs and mountains, or underground layers.
Add missing documentation of 'ore_param2' parameter.
* Fix animation frame_speed and blend loosing precision due to incorrect data type
Add lua function set_animation_frame_speed to update the frame speed without resetting the animation to start
* Fix HP transport + some double <-> float problems
TOCLIENT_HP transport u16 hp as a u8, use u16 HP, this prevent HP over 255 to overflow across network
* Fix more double/float problem in serverpackethandler & remove implicit struct type for TileAnimationParams
* Fix connection unittests container
* Formspec: Add options to set background color and opacity (fullscreen mode)
* Enhance previous comment: Set formspec background when regenerate UI.

* Add a setting for default background color into formspec, separated from fullscreen
* Add a little performance gain on formspecs using a const ref instead of copying formspec string
* Refactor clientevent structure
* Move structure outside of client header
* Create client events on heap not stack, this remove the ClientEvent object copy
* Use clientEventHandler to route events
* Alternative code for slipping
- does not depend on frame rate
- controllable via environment variables for now
* Adjust slipping speed for item entities too.
* Final version of framerate-independent slippery code
* Remove dead code and fix formatting
* getStandingNodePos should only look 0.05 nodes downwards
This ensures that, even if the player is standing on a partially
filled node, this node is used as the standing node and not the
node below it.
Specific use: enables slippery slabs
* Exchange global getStandingPosNode change for local inline change
Reverts previous commit
* Revert the item movement changes
* Slippery nodes now slip over cliffs and edges
Players no longer suddenly stop before falling off.
Also refactored slippery code into getSlipFactor method.
* Slipping over an edge gated by player's is_slipping state
A new flag for just this case, to reduce costly node lookups in
the normal case of leaning over a non-slippery edge.
Public access for consistency and potential future uses.

* Releasing buttons unblocks the respective action again
* Useful for inexperienced users in creative mode where default
repeat times may be too short
* Safe placing (right click repetition) does not need a guarding flag
* Added new setting to minetest.conf.example

* Also fix NetworkPacket code style & make it under clang-format
* Respect object property hp_max field for players
This allows modders to configure the maximal HP per player
* Statbars: Downscale bar to full 20 HP when exceeding this value
Add default max HP for players and breath constants to builtin
Document the constants
* Rename PLAYER_MAX_HP -> PLAYER_MAX_HP_DEFAULT
the BS constant
implicitly promotes all position calculations it is used in to double even
though positions (= v3f) are only meant to be floats.
There are many, many similar occurrences everywhere, but I'm not willing to
hunt down all; I only fixed the little part I'm already familiar with.

When minetest is launched, if there was no nameprovided in
configuration or parameters, the game would not show any error in
console. if the --go parameter was also prowided, the game would
exit without an error. This is undesired behavior, so this merged
commit add the missing function that displays the missing error
message in console.
Gives starting singleplayer games this subtle "dawn of a new world" feel.
I would have set it even earlier (up to 4:45am), but I was worried that in
some pre-existing games the player could be overwhelmed by hostile
mobs right at the start, seriously changing gameplay.
It's just the default, individual games should be able to override it, and
for public servers it's irrelevant anyway, because only the first player to
set foot in the world will notice, and that's usually the server admin.
Another small general problem: the player is always standing exactly on the
bondary between 2 nodes e.g. Y=1.5 is exactly between nodes Y=1 and Y=2.
floatToInt() and myround() will round +/-n.5 always 'outwards' to +/-(n+1),
which means they behave differently depending on where you are: they round
upwards above sea level and downwards when underground. This inconsistency
comes from the way the coordinates are calculated, independent of the
specific C++ code.
The result is a tiny bit of lost performance when moving underground,
because 1 node level more than necessary is checked for collisions. This can
be amended by adding a tiny offset to minpos_f.Y, like @paramat suggested.
This is not an elegant solution, but still better than wasting CPU.
To determine the area (nodes) where a player movement took place
collisionMoveSimple() first took the old/new player coordinates and rounded
them to integers, then added the player character's collision box and
implicitely rounded the result. This has 2 problems:
Rounding the position and the box seperately, then adding the resulting
integers means you get twice the rounding error. And implicit rounding
always rounds towards 0.0, unlike floatToInt(), which rounds towards the
closest integer.
Previous (simplified) behavior: round(pos)+(int)box, for example player at
Y=0.9, body is 1.75m high: round(0.9)+(int)1.75 = 1+1 = 2.
==> A character's height of 1.75m always got rounded down to 1m, its width
of +/-0.3 even became 0.
Fixed by adding the floats first, then rounding properly: round(pos+box) =
round(0.9+1.75) = round(2.65) = 3.
Construct dungeons from the node defined as biome 'node_stone' if
'mapgen_stone', 'mapgen_desert_stone' and 'mapgen_sandstone' are not
detected.
Feature long-intended by kwolekr/hmmmm and present in code as a TODO.
Move point at which light is sampled up to 0.5 nodes above foot level,
to avoid that point sometimes passing into the node below causing the
model to go dark.
The getBackgroundBrightness() function detects darkness in the view direction
to decide when to make the skybox dark. The volume checked was too narrow and
missed the left and right edges of the view, too easily causing a dark skybox.
Widen the checked volume to match a FOV of 72 degrees and a 16:9 aspect ratio
game window.
Remove usage of the SharedBuffer in zlib compression which has two problems:
* We copied the whole memory block to compress it (not good with mapblocks)
* We copied sometimes strings to SharedBuffer to SharedBuffer (2nd time)
Use this method in MapNode::serializeBulk + optimize serialization but merging 3 identical loops in a single loop
correctBlockNodeIds does 2 lookups for each loaded node, one to translate DB ID to name and a second to translate name to real ID. Name to real ID is very consumming if done on every node. As mapblocks are in most cases composed of many identical adjacent nodes, cache previous source and destination id and use them on the next node to prevent any lookup on those maps.
This reduce the function load from 15% of my CPU usage to ~0.7%, on the test, calls was reduced from 2.5M lookups to 42k lookups, it's a huge performance gain
* TileLayer: use shared_ptr for vector framespec
This reduce memory copy of TileLayer from (4 to 16) * FrameSpec where FrameSpec = (sizeof(int) + 3 * sizeof(ptr)) to int + sizeof(ptr)
Callgrind difference

* Fix one push_back to use vector::emplace_back & optimize inclusions
* VoxelManip cleanups (const ref, const move) permitting to improve a little bit performance
* VoxelArea: precalculate extent (performance enhancement)
This permits to reduce extend high cost to zero and drop many v3s16 object creation/removal to calculate extent
It rebalance the client thread update to updateFastFaceRow instead of MapBlockMesh generation
This will also benefits to mapgen
Allows setting of the mountain 'zero level' (y where density gradient is zero).
It is easy to vertically shift smooth terrain by editing noise parameter 'offset',
but vertically shifting mountain terrain was complex and imprecise, involving
making a calculation based on an average of the mountain height parameter.
Ensure in-cloud fog is always stronger than outside-of-cloud-fog even when
using a small view range.
Also limit in-cloud fog range to a maximum of 32 nodes to keep it fairly
strong when using a large view range.
The change from 800x600 to 1024x576 (16:9) was a reduction in height which caused
user interface to become smaller.
Continue to use width 1024 as it is a common small screen width.
* [CSM] Add flavour limits controlled by server
Server send flavour limits to client permitting to disable or limit some Lua calls
* Add limits for reading nodedefs and itemdefs
* flavour: Add lookup node limits
* Merge get_node_or_nil into get_node.
Sending fake node doesn't make sense in CSM, just return nil if node is not available for any reason
* Add node range customization when noderange flavour is enabled (default 8 nodes)
* Limit nodes range & disable chat message sending by default
* Bump protocol version
Spawn player 1 node higher to avoid spawning waist-deep in a possible
biome 'dust' node, such as tundra snowblock.
Tune default offset to spawn players in a more interesting location on the
mandelbrot sets, on a raised area that looks like a spawn platform.
Tune julia parameters to help avoid spawn search failing, especially for
fractal 6.
For consistency return to 'FPS =', add comma before FPS.
Remove 'R' from 'range_all' as may be re-keymapped.
Remove inconsistent brackets from 'range_all'.
Change 'v_range' to 'view_range'.

Add spaces around '=' in yaw display.
Remove brackets from around 'yaw' and 'seed'.
Move 'pointing_at' to 3rd line.
Remove 'param1' (0 for all solid nodes and unreadable for light sources due to
light bank encoding).
Remove file name of pointed node top tile (this also removes the need to get
ContentFeatures for the node, slightly improving performance).
Replace quotes around node data with brackets, looks better and more consistent.
Add 'guitext3' for third line.
Use 'setVisible' for all 3 lines to control the setting of each text rectangle.
Improve logic of 3rd line to only run code it needs to depending on whether
pointing data is avaialble and whether node is not 'ignore' and not 'unknown'.

Add 'biome_zero_level' argument to 'generateBiomes()', 'deco_zero_level'
argument to 'placeAllDecos()' and 'ore_zero_level' to 'placeAllOres()'
to allow mapgens to vertically shift the registered biomes, decorations
and ores per-mapchunk.
Will also allow many realm possibilities in future mapgens.
Useful for underwater plants.
Node consists of a base cube plus a plantlike extension that can pass through
liquid nodes above without creating air bubbles or interfering with liquid flow.
Uses paramtype2 'leveled', param2 defines height of plantlike extension.
This commit introduces Raycast, a Lua user object, which can be
used to perform a raycast on the map. The ray is continuable, so one can
also get hidden nodes (for example to see trough glass).

The 'absheight' flag was added years ago for the floatlands of 'indev'
mapgen (now deleted). The feature mirrored all ore placement around y = 0
to place ores in floatlands.
In MTG we now use dedicated ore registrations for floatlands.
The feature is crude, inflexible, problematic and very rarely used, it
also makes ore vertical range code more complex.
Minetest 0.5 is a good chance to remove the feature.
The flag itself remains to not break flag values.

Some settings of paramters can cause mgv7 variables to be -inf, nan or -nan.
This can cause massive vertical columns of water to appear above sea level.
As with 'large_cave_depth', lava depth was previously a fixed y value and
therefore incompatible with the ability to shift terrain vertically.
Add 'lava_depth' mapgen parameter to mgflat, mgfractal, mgv5, mgv7.
The value cannot be fixed because we can shift terrain vertically.
This also makes these mapgens consistent with mgflat and mgvalleys which
have 'large_cave_depth' parameters.
When adding items to an empty ItemStack, limit the number of items taken
based on the maximum stack size in the item description.
Likewise, when checking whether items will fit into an empty ItemStack,
only absorb as many items as are allowed in a single stack and return the rest.

Previously, the carving of rivers was disabled above 'shadow_limit' even if
floatlands were disabled. This caused rivers to be unnecessarily disabled if
mapgen was customised to have surface level above y = 1024.
Previously, maximum spawn level was set to 'water_level + 16'. This would result
in spawn search failing if terrain had been customised to be much higher than
'water_level' at all points.
Also raise spawn level by 1 node to avoid spawning half-buried in a biome 'dust'
node such as 'default:snowblock'.
* C++11 patchset 10: continue cleanup on constructors

* remove some unused since years exception classes
* remove unused & empty debug_stacks_init
* remove unused & empty content_nodemeta_serialize_legacy
* remove forgotten useless bool (bouncy) in collision.cpp code
Previously, when removing decorations we searched upwards and removed until we
found air or water. However, the node above the decoration can be 'ignore' if
a stacked decoration extends into the volume above the mapchunk. The result
could be a problematic column of air placed in the volume of 'ignore'. The
unnecessary placing of air also slows the function.
Add a check for 'ignore' nodes when removing decorations.
Recently we started to remove decorations if the dirt below was flowed away,
but this did not check for stacked decorations, causing them to have only
their lowest node removed.
Also, placed mud could partially bury stacked decorations.
Remove 'old_is_water' bool which on testing is never true.
Add new function 'moveMud()' to reduce indentation.
Remove stacked decoration nodes above a removed decoration.
Remove stacked decorations partially buried in placed mud.
thread_local permits to limit variable lifetime to thread duration. Use it on each setting place which uses static to cache variable result only for thread lifetime. This permits to keep the same performance level & reconfigure server from MT gui in those various variables places.
Add thread_local to undersampling calculation too.

Previously, findSpawnPos() did not take the 'mapgen_limit' setting into account,
a small limit often resulted in a spawn out in the void.
Use the recently added 'calcMapgenEdges()' to get max spawn range through a new
mapgenParams function 'getSpawnRangeMax()'.
Previously, when a player respawned into a world, 'objectpos_over_limit()' was
used as a check, which was inaccurate.
Use the recently added 'saoPosOverLimit()' to get exact mapgen edges.
Also fix default value of 'm_sao_limit_min'.
These code be generated by CSM, a modded client or just copy and pasted by the player.
Changes
- Update configuration example and setting translation file.
- Remove colour codes before logging chat.
- Add setting to remove colour codes before processing the chat.
C++11 implement function deleting, it's generally used to prevent some object copy
In script API use this function removal on ScriptApiBase instead of ScriptApiClient/Server/MainMenu, this affect all ScriptApis
Move DISABLE_CLASS_COPY with constructor, the deleted function permit to replace function in its original place
* Have the server send the player list to the client
Currently the client generates the player list based on the Client active object list, the issue with this is that we can't be sure all player active objects will be sent to the client, so this could result in players showing up when someone run `/status` but auto complete not working with their nick and CSM not being aware of the player
* Move GCC to GCC 6 & GCC 7
* Move Clang to Clang 3.6 & Clang 4.0
* LINT moves from Clang 3.9 to Clang 4.0
* Move XCode 7.3 to 8.0
* Use more travis tricks to install compilers instead of adding complexity to our build script
* Clang format fixes on checked files (compat Cpp11 instead of Cpp03)
* Mingw GCC update from 4.8.4 to 5.3 (Ubuntu Xenial)
* Drop mingw cmake generated files and add them to gitignore
* LuaEntitySAO: Remove beyond outermost mapchunk edges
Based on a commit by, and with help from, nerzhul.
Add 2 functions to class Mapgen:
A function to calculate actual mapgen edges, called from the Mapgen constructor.
A function called indirectly from content_sao.cpp per entity step to check SAO
position is within mapgen edges.
* Calculate borders from params not mapgen, which is not available everytime
* Use only one label instead of two for the soundText, this permit to ensure both label & values are aligned
* Add '%' character too, to reflect it's a percentage volume
* Remove rect on regenerateGui (upper part) which shadows outer part and which is not needed outside of the DesiredRect affectation
Fix issue #5837
* Enhance ABM performance a little bit by removing two std::set copy
* ActiveBlockModifier::getTriggerContents now returns a const ref
* ActiveBlockModifier::getRequiredNeighbors now returns a const ref
* ActiveBlockModifier::getRequiredNeighbors is now purely virtual
* Little code style fix
Mudflow of a neighbouring mapchunk extends into a mapchunk's edge, and could
remove 'dirt with grass' from under a decoration, creating unsupported
decorations.
Remove any decoration above if a 'dirt with grass' node is removed by mudflow.
* Revert 1469424075affce7c27bb44e5a5cbd51485e44b2 and fix wrong char position when doing mouse selection on intlGUIEditBox
position should look at current line not the whole text and shift 1 character on the last line (due to \0 string delimiter)
* Finish the fix and prevent values under zero for getCursorPos which crash the program if found
* Forget to remove old comment
* fix zero to NULL
* Fix typo
Fixes a crash caused in MTGame by breaking and right-clicking a chest.
If loading meta, digging, node can disappear and we looked at meta, which is wrong because meta became NULL.
Pointer is invalidated and we read wrong memory area
Seems the diff mode doesn't work well, PR are detected as working whereas in master it's shown it's problematic (and really problematic). Use same check everywhere
* [CSM] Add send_chat_message and run_server_chatcommand API functions
* Add client-side chat message rate limiting
* Limit out chat queue size
* [CSM] Add minetest.clear_out_chat_queue API function and .clear_chat_queue chatcommand
* Last fixes/cleanups before merge
* Allow enabling and disabling mods.
* Re-fix 605599b6f150b89ba6539c4d088231b326adcb48
This breaks some chars like € in chat.
Instead verify is char is a non control char -> iswcntrl
Use runData.dig_time_complete instead of params.time to find out whether it's instant digging.
runData.dig_time_complete is set to something very big if the node can't be dug, whereas param.time is 0 when digging is impossible or it's instant digging. So not using param.time fixes#5728.
Previously, every particle was rendered by (even if not actually visible to)
the client regardless of distance. This significantly reduced client FPS.
Acts clientside, particle spawners are always sent to clients, but each
particle is checked for distance from the player.
As with 'add particle' the distance limit is set to 'max block send distance'
as this determines how far a client can see.
Previously, every individual particle on a server is sent to, and rendered by
(even if not actually visible), every client regardless of distance. This
significantly reduces client FPS and creates unnecessary network traffic.
Maximum distance is set by 'max block send distance' as this determines how far
a client is able to see.
Also disable CavesRandomWalk at a safer distance from caverns.
Excavating liquids in cavern code is unnecessary as in practice we are already
successfully disabling the generation of liquid caves that could intersect
with caverns and cause excessive amounts of spreading liquids in caverns.
However to be safer this commit now disables liquid caves at a larger distance
from caverns, to compensate for liquid caves being able to generate up to a
mapblock beyond a mapchunk border.
Not excavating liquids in cavern code also allows a feature i am working on in
experimental new core mapgens, but also allows for more flexibility in future.
* Move KeyList & InputHandler from game.h to client/inputhandler.h
We have a header for inputs, move inputhandler class & related keylist object to it
Also introduce a cpp file for MyEventReceiver::OnEvent function in inputhandler.h because a so huge function doesn't needs to be inlined
* Pass clang-format on inputhandler.{cpp,h} (compatible)
- Split movement keys into separate entries.
- Increase buffer size due to the above change.
- Change capitalisation.
- Remove code-style violating white spaces.
* Rework escape/pause menu
- Remove build information
- Use current controls instead of default controls
- Add information about the current server in place of the build information
- Add text saying the game is paused to if in singleplayer mode.
rework pause/escape menu
* improve consistency + display server_name
* read_schematic_replacements: ensure fields are strings
add a type check before reading strings on read_schematic_replacements deserializer
* throw LuaError instead of asserting the whole client
Recent commit 45ab62d6a3d90ab3b97aec88251a766cb5dd1899 had a coding error that
made climbing out of water difficult due to an incorrect value of the step height
when not 'touching ground'.
It also incorrectly multiplied the custom stepheight by BS, resulting in being
able to step-up 2 nodes if set to the default of 0.6, or even 0.3.
Also the implementation was wrong because it customised the step height when
not 'touching ground', this step height is for a slight rise when catching the
edge of a node during a jump, and should always remain at 0.2 * BS.
Also remove hardcoded MTGame node.
The 'water surface shader' was duplicated shader code in preparation for
intended new water surface shaders. For development purposes the MTGame node
'default:water_source' had it's top tile assigned to 'water surface shader'.
Due to shader duplication this commit does not cause any change to shader
behaviour.
* Player attrs: permits to remove an attribute by setting value to nil
When doing player:set_attribute("attr", nil) remove attribute
Also remove a useless check on C++ API part (already done by checkplayer)
Fix#5709
Recent commit b6f4a9c7e1a4f0bac66fd6f6ff844425ac775975 removed a hardcoded
player collisionbox which resulted on falling back to an incorrect default.
This stopped players walking through 2-node high spaces and made the player
slightly wider.
Improve docs for custom player collisionbox feature and reformat nearby lines.
This unifies the settings APIs.
This also unifies the sync and async registration APIs, since the async
registration API did not support adding non-functions to the API table.
Default true.
Add 'm_clouds_enabled' bool to sky.h, set from new bool in 'set sky' API.
Make 'getCloudsVisible()' depend on 'm_clouds_enabled' instead of
'm_visible' (whether normal sky is visible).
* Optimize updateFastFaceRow processing by removing some TileSpec copy
It permit to decrease this function from 54% runtime to 45% and reduce copy from 14% runtime to 12.5%
getTileInfo also reduced from 27% to 23%
* makeFastFace should use a const ref too
this trigger a const pointer need in the underlying function
Also fix some code style and prevent calculating 4 times the same position at a point
* Reduce a comparison cost for lights in updateFastFaceRow
Instead of create fake events on the stack on each loop call (Game::run), verify is queue is empty or not and handle event directly if there is.
This prevents fake ClientEvent creation & memory allocations
Same fix is also applied on ClientEnvironment, & rename getClientEvent to getClientEnvEvent to match ClientEnvEvent object
Despite the split of TileSpec into TileDef and TileLayer, the
TileLayer struct is still 66 bytes large, and doesn't fit in
a single cacheline.
I'm moving the color member to cacheline 2, in the hope that it
is less used and the compiler loads all the hot members in a single
cacheline instead. Only color sits now in cacheline 2, all the
other members are in cacheline 1.
Note: is_color is probably rarely set, most nodes will likely
not use hardware coloring, but this may change in the future.
Ideally, this class is shrunk to 64 bytes.
Torches are dug instantly again.
When the digging time is 0, a delay of 0.15 seconds is added between digging nodes. If the left mouse button is released, the delay is set to 0, thus click-digging.
We introduce a new value for "waving" - 2:
0 - waving disabled
1 - wave like a plant
2 - wave like a leave
Plantlike nodes will only allow waving = 1, but for leaves we will
permit both 1 and 2 since current minetest_game sets it to 1 for
all leaves. This makes it somewhat backwards compatible.
For mesh and nodebox, values 1 and 2 are both valid, and the node
can wave in both fashions as desired.
I've tested this with the crops:corn plants, which are mesh nodes,
and the results are really good. The code change is trivial as
well, so I've opted to document the waving parameter in lua_api.txt
because it was missing from there.
Nodeboxes likely will not wave properly unless waving = 2. However
it's possible that waving=1 may be desired by some mod developers
for geometries I have not tried, so the code will not prohibit
either value for mesh and nodebox drawtypes.
Add lua_api.txt documentation for this feature and document both
the existing functionality and the expansion to mesh and nodebox
drawtypes.
Client: Don't send `TOSERVER_RECEIVED_MEDIA` since it's not used anymore
Server: Handle `TOSERVER_RECEIVED_MEDIA` using `Server::handleCommand_Deprecated`
* Remove redundant view_bobbing setting
Also fixes bug where disabling view_bobbing disables footstep sounds.
* Removes redundant view_bobbing setting
Setting view_bobbing amount to 0 is now the only way to
turn view_bobbing on and off. Also fixed a bug where footstep
sounds would not play when view_bobbing was disabled.

Fix crash caused by destructor 'delete' on noise objects that are not
created due to mapgen options.
Crash was caused by commit 57eaf62c697cec91890d9cb28d10385d293d2d3f
The 'sneak glitch' physics override now controls whether a player can
use the new move code replications of the old sneak side-effects:
sneak ladders and 2 node sneak jump. This completes our intention to
replicate the old sneak side-effects in new code and provide them as
an option that is disabled by default.
This callback is called if a liquid definitely floods a non-air
node on the map. The callback arguments are (pos, oldnode, newnode)
and can return a `bool` value indicating whether flooding the
node should be cancelled (`return true` will prevent the node
from flooding).
Documentation is added, the callback function was tested with a
modified minetest_game.
Note that `return true` will likely cause the node's `on_flood()`
callback to be called every second until the node gets removed,
so care must be taken to prevent many callbacks from using this
return value. The current default liquid update interval is 1.0
seconds, which isn't unmanageable.
The larger aim of this patch is to remove the lava cooling ABM,
which is a significant cost to idle servers that have lava on their
map. This callback will be much more efficient.
if mod is a reference to a class member a variable swap breaks.
We should find a way to keep this const ref if possible.
Added a comment about this in header
* Make CI happy with code style on master
* guiFileSelectMenu: remove useless includes
* some performance fixes pointed by cppcheck
* remove some useless casts
* TextDest: remove unused setFormSpec function
This is not really different from the light update of a voxel
manipulator. This update does not assume that the lighting was correct
before, therefore it is useful for correction.
Also expose this function to the Lua API for light correction, and
allow voxel manipulators not to update the light.
I play with the TAB key bound to the inventory. However, the
code here assumes that TAB means "close formspec" in all contexts,
including the main menu. This causes my game to exit when I attempt
to TAB in between USERNAME and PASSWORD fields.
We know when m_client != NULL that the game is a client game and
not in the main menu, and then it's OK to use the INVENTORY bound
key to exit the formspec, since it's not the main menu.
Cache size is configurable by the meshgen_block_cache_size (default 20 MB).
New profiler stats:
- MeshUpdateQueue MapBlock cache hit %
- MeshUpdateQueue MapBlock cache size kB
Removes one type of stutter that was seen on the client when received MapBlocks
were being handled. (the "MeshMakeData::fill" stutter)
Kind of related to at least #5239
Originally preceded by these commits, now includes them:
- Move the mesh generator thread into src/mesh_generator_thread.{cpp,h}
- mesh_generator_thread.cpp: Update code style
- MeshUpdateThread: Modify interface to house a different implementation: Actual functionality will be changed by next commits.
- MeshMakeData: Add fillBlockData() interface (so that caller can fill in stuff from eg. a MapBlock cache)
Temporary option for the old move code for specific old sneak behaviour.
Enabled by setting the added 'new move' physics override to false.
By default 'new move' is true.
* Resource leak: CHECK_FILE_ERR returns, without freeing chunk_name.

Please review again @nerzhul . Thanks!
* Satisfy nerzhul
Re-creates the old sneak-jump behaviour in new code.
Enabled by the 'sneak glitch' physics override.
When a ledge is detected the jump speed modifier is set to the larger
of 'physics override jump' and 1.3 to allow a 2-node climb-up.
An unexpected side-effect is the simple sneak ladder working smoothly.
Adds uniform undersampling for the 3D rendered scene. GUI elements
are not undersampled, resulting in better playability for users
with low-performance platforms with readable fonts and formspecs.
The undersampling setting can be set to 0 (disabled), 2, 3, 4 pixels
which translates into a resolution reduction of x4, x9 or x16, and
is significant.
Adds the possibility to colorize item stacks based on their metadata.
In the item/node definition you can specify palette (an image file)
and color (fallback color if the item has no palette or metadata).
Then you can add palette_index to the metadata.
Dropped itemstacks with different colors do not merge.
- If the hand can dig a node the item wielded can't, allow to dig it anyway.
- Fix the API callbacks from setting the hand instead of the wielded item.
* Add joystick type detection (with joystick_type setting to override it)
* Fix multiple joysticks from interfering with each other by only reading from one (add joystick_id setting)
* Add support for Xbox controllers
* Proper support for continuation indents in clang format
* make src/wieldmesh.h proper and remove it from whitelist
* Add CLion default build directories in .gitignore
Add to MapgenBasic for use by multiple mapgens.
Add to mgv5 and mgv7, enabled by default.
Similar to mgvalleys caverns but half the scale.
Parameters for upper y limit, distance caverns taper to full size, and
noise threshold (full cavern size).
As with mgvalleys caverns are generated first and classic caves are
disabled in any mapchunk containing a cavern, to avoid excessive
spreading volumes of liquids.
This also avoids floating blobs of liquid where a large classic cave
has overgenerated out into a neighbouring previously-generated mapchunk.
* Update embedded jsoncpp from unk version to 0.10.6
0.10.6 is last release without c++11
* Make jsoncpp more compliant with its amalgamate
Jsoncpp cpp file should be upper, make the library like it does in amalgamate
* Reorganization: move minetest embedded libs outside of source tree to /lib
* Fix a dead grep in LINT
Add the missing paramtype2 for param2 controlling the liquid level
inside the glasslike_framed drawtype.
Add missing documentation of the feature to lua_api.txt.
Update and improve comments for drawtype enumerations in nodedef.h.
The setting limits map generation but affects nothing else.
Add 'mapgen_limit' to global mapgen parameters.
Move 'blockpos_over_mapgen_limit()' to the only place it is called
from: map.cpp.
Allow teleportation to any part of the world even if over the set
mapgen limit.
Simplify the reading of this limit in mgvalleys.
Remove the 'map_generation_limit' setting.
* [BUILD] Add clang format + build skipping
* Add clang-format tool to check codestyle.
Warning: it check the whole modified file, not the diff part, it's why it's lazy. Please also look if rules are perfect, i take the Linux codestyle from LLVM site
Fix issue #5415
* Skip building project if no file is modified
* Fix a wrong brace to trigger LINT
* Make lint step outside of unix build scope
* Add AccessModifierOffset: -8
* Typo fix & needs compile fix
* Fix header priorities
* Some performance optimizations
This is globally removing some memory useless copy
* use a const ref return on std::string Settings::get to prevent data copy on getters which doesn't need to copy it
* pass some stack created strings to static const as they are not modified anywhere
* Camera: return nametags per const ref instead of a list pointer, we only need to read it
* INodeDefManager: getAll should be a result ref writer instead of a return copy
* INodeDefManager: getAlias should return a const std::string ref
* Minimap: unroll a Scolor creation in blitMinimapPixersToImageRadar to prvent many variable construct/destruct which are unneeded (we rewrite the content in the loop)
* CNodeDefManager::updateAliases: prevent a idef getall copy
* Profiler: constness
* rollback_interface: create real_name later, and use const ref
* MapBlockMesh updateFastFaceRow: unroll TileSpec next_tile, which has a cost of 1.8% CPU due to variable allocation/destruction,
* MapBlockMesh updateFastFaceRow: copy next_tile to tile only if it's a different tilespec
* MapBlockMesh updateFastFaceRow: use memcpy to copy next_lights to lights to do it in a single cpu operation
The previous implementation applied the setting to blockpos_over_limit(),
objectpos_over_limit() and in createSector(), causing many bugs near the
world edge.
First revert the previous implementation.
Rename blockpos_over_limit() to blockpos_over_max_limit() for clarity.
Add a new function to mapblock.h called blockpos_over_mapgen_limit() that
checks against the map_generation_limit setting, and call this only from
the code that decides where mapgen stops.
Use MAX_MAP_GENERATION_LIMIT in objectpos_over_limit() to reduce the
chance of bugs, there is no need to use map_generation_limit here.
* showPauseMenu is now part of game
* remove many flags parameters passed to game functions, use the member.
* rename VolatileRunFlags to GameUIFlags (this will permit to share structure with client and CSM
* updatePointedThing: remove pointer ref, we already have the pointer in rundata
* move some attributes outside of VolatileRunFlags after renaming, to game class
* rename statustext to m_statustext
* make some const variables static
* All those changes permit to reduce a little bit function class cost and will permit to interface CSM with some interesting Game flags
* Expose GameUIFlags to client
* Client now have GameUIFlags parameter and setters for other classes
* Fix minimap show/hide in Lua because we now have access to the real flag
GameRunData is passed on many game functions, or one of its attributes whereas it's a member of the class. Remove it from functions arguments and call object directly from concerned functions.
This will reduce a little bit the Game class loop usage & very little bit the memory usage (due to non creation of pointer/references)
It is harmless for a biome listed in an ore or decoration registration
to be missing.
Now that we are registering certain biomes or not based on options
(such as floatland biomes), the biome lists in ore and decoration
registrations trigger these error messages, avoiding these error
messages would need a large amount of duplication of ore and decoration
registrations.
Sneaking won't actually hover you in the air, releasing shift guarantees not
falling down (same as in MC).
Sneak-jump no longer goes higher than a normal jump (^ was required for this).
Sneaking no longer avoids fall damage.
You can sneak on partial nodes (slabs, sideways slabs) correctly.
Sneaking doesn't "go out" as far anymore (0.29 instead of 0.4).
Can't jump when sneaking out as far as possible (breaks the sneak ladder).

This commit introduces a new bulk node lighting algorithm to minimize
lighting bugs during l-system tree generation, schematic placement and
non-mapgen-object lua voxelmanip light calculation.
If the block above the changed area is not loaded, it gets loaded to avoid
lighting bugs.
Light is updated as soon as write_to_map is called on a voxel manipulator,
therefore update_map does nothing.
If you happen to have a font_path setting that is incorrect,
minetest will just attempt to start the gui without a valid
font which leads to a segfault later on.
We can attempt to load the fallback font path fairly easy,
but if that fails we should give up with a proper error message
and not a weird segfault later. This forces an abort() if
the fallback fails as well, and prints a useful error
message to the console.
Add:
Bool for 'only_in_ground'.
Min and max corridor length.
Min and max room size with X, Y, Z components.
Min and max large room size with X, Y, Z components.
'only_in_ground = false' allows core mapgens to create structures
in air and water using dungeongen.
Corridor length parameters replace a fixed random range.
Room size parameters replace the former system where one parameter
'roomsize' was added to fixed random ranges.
All parameters are set for no change to current dungeon behaviour.
Remove some now-redundant and long-unused code.
Correct node placement prediction for attached colorwallmounted nodes.
Correct placement direction for colorfacedir and colorwallmounted nodes.
Correct detatch mechanism for attached colorwallmounted nodes.
Placing a structure that extends into mapblocks that extend past
map_gen_limit causes a crash. For example a sapling growing at the
world edge which adds leaves beyond the edge, or placing a structure
using the lua voxelmanip, or placing a schematic or l-system tree.
Do not run the 'load_if_inexistent' block of code if the mapblock
is over limit, this also marks the mapblock with the flag
VMANIP_BLOCK_DATA_INEXIST which later prevents blitting back those
mapblocks.
This fix therefore uses existing functionality by having the same
effect as the 'load_if_inexistent' bool being false.
This reverts the removal of Droid Sans as fallback font. The
license for this font used to be GPL2. I've updated the font
files to Liberation 2.00, which are SIL, and do not require
us to ship source code.
I've attempted to fix all the attribution and license strings,
and used the strings as provided by redhat for attribution
to make sure they're correct.
Last, I've removed a bunch of executable bits on files that do
not need them.
Fixes#5231
Previously in tunnel entrance floors only a single biome 'top' node was
placed and 'filler' nodes were missing.
Place 'top' and 'filler' nodes in tunnel entrance floors with depths
defined by the biome.
In tunnel entrances under rivers 'riverbed' nodes are placed to the
biome-defined depth.
Reduce the object limit by mapblock size, to avoid objects being
added just inside the map generation limit but in a block and sector
that extend beyond the map generation limit.
Change notification of 'objectpos over limit' from red in-chat ERROR
to in-terminal only WARNING, since this will happen often using mob
mods near the world's edge.
force_delete=true is usually set at shutdown in order to
also remove PlayerSAOs, however when too many objects
per block are detected force_delete is also set to true.
This was intended only for the current loop iteration but
obviously persisted to the next iterations thereby
deleting all other remaining SAOs.
It appears we were shipping font files without license text, and I
had my doubts about the bitmap fonts being usable directly.
This replaces existing TTF fonts with Apache-2.0 licensed fonts from
chome core (Cousine, Arimo, Tinos). Include the full license file
for all three fonts.
The Lucida Sans font bitmap is removed entirely for non-freetype
builds. There is therefore only mono fonts for non-freetype builds.
Fix footstep sounds coming from nodes to either side when walking on a
1 node wide row of nodebox slabs such as default:snow.
Fix sand footsteps when swimming in 1 node deep water.
Use a new function 'getFootstepNodePos()' instead of 'getStandingNodePos()'
to avoid using a horizontally-offset 'sneak node' for sounds.
Sound is selected from the node BS * 0.05 below the player's feet, so
that 1/16th slabs will play the slab sound but 1/32nd slabs will not.
If the player is not 'touching ground' the node detection position is
changed to BS * 0.5 below to preserve footstep sounds when landing after
a jump or fall.
This re-applies 2 commits that were reverted.
Visual_scale was applied twice to plantlike by accident sometime between
2011 and 2013, squaring the requested scale value. Visual_scale is
correctly applied once in it's other uses in signlike and torchlike.
Two lines of code are removed, they also had no effect for the vast
majority of nodes with the default visual_scale of 1.0.
The texture continues to have it's base at ground level.
Send sqrt(visual_scale) to old clients.
Keep compatibility with protocol < 30 clients now that visual_scale
is no longer applied twice to plantlike drawtype and mods are being
updated to a new value.
We want to reduce the chance that we get lots and lots of node
timers all happening once a second, because we're better off doing
small bits of work as they are available.
Reducing this to 0.2 seconds will greatly reduce the total amount
of nodetimers that elapse at the same instance, while not effecting
total work load. This results in a far better chance of the server
keeping up with work loads.
In createPlayingSoundAt(), AL_ROLLOFF_FACTOR is not set, so it has
the default value of 1.0, this makes the equation of the currently
used AL_EXPONENT_DISTANCE distance model identical to the equation
of the simpler AL_INVERSE_DISTANCE distance model.
Using AL_INVERSE_DISTANCE means an exponent is not processed,
exponents are quite intensive to process.
There is no change in sound attenuation behaviour.
The commented-out AL_ROLLOFF_FACTOR value is removed as it would
now have a different effect if used.
* mod can create a ModMetadata object where store its values and retrieve it.
* Modmetadata object can only be fetched at mod loading
* Save when modified using same time as map interval or at server stop
* add helper function to get mod storage path
* ModMetadata has exactly same calls than all every other Metadata
While experimenting with entities I ran into this unresolvable
error where the server is sending some texture that the client
crashes on. The crash prevents the client from ever reconnecting,
resulting in a server that has to use clearobjects.

Gravel now falls back to stone.
Gravel is not a particularly fundamental node, allowing it to fall back
to stone frees up subgames from having to include a gravel node.
Non-blob-ore gravel is only present in mgv6 as extremely rare 'gravel
biomes'.
Add a fallback node for stair_desert_stone to avoid ignore placed
in Minimal subgame desert dungeons.
Don't allow river_water_source to fallback to water_source as river
water needs to be non-renewable and have a short flow range.
Make stair_sandstonebrick fall back to sandstonebrick instead of
sandstone.
Re-order some lines.
Add a comment.
Fix missing decorations at horizontal chunk borders by adding
'updateHeightmap()' after terrain generation.
Swap order of 'calculateNoise' and 'calcBiomeNoise' because
'calculateNoise' modifies the heat and humidity maps created in
'calcBiomeNoise'.
Remove confusing comment, code block is not just for mods and
seems essential for correct mapgen behaviour.
Previously, m_move_pool could accomodate the client moving from the new
position to the old one, and the server accepted the client to go back
to its old position. However, it couldn't then accomodate the client
moving from its old to its new position, and therefore would reset position
to the old position. Thus, by emptying m_move_pool after a teleport, the
server no longer accepts the client to go back to its old position. A
drawback is however that a laggy client *will* trigger a few
"moved_too_fast" anticheats before being told about its new position.
Don't report player cheated if caused by lag.
Fixes#5118
Keep compatibility with protocol < 30 clients now that visual_scale
is no longer applied twice to plantlike drawtype and mods are being
updated to a new value.
For Game::openConsole() and GUIChatConsole::openConsole() the
parameter name 'height' is misleading because it's actually a
percentage of the screen/window height.
If a newly spawned thread called getThreadId or getThreadHandle before
the spawning thread finished saving the thread handle, then the
handle/id would be used uninitialized. This would cause the threading
tests to fail since isCurrentThread would return false, and if Minetest
is built with C++11 support the std::thread object pointer would be
dereferenced while ininitialized, causing a segmentation fault.
This fixes the issue by using a mutex to force the spawned thread to
wait for the spawning thread to finish initializing the thread object.
An alternative way to handle this would be to also set the thread
handle/id in the started thread but this wouldn't work for C++11
builds because there's no way to get the partially constructed object.
Visual_scale was applied twice to plantlike by accident sometime between
2011 and 2013, squaring the requested scale value. Visual_scale is
correctly applied once in it's other uses in signlike and torchlike.
Two lines of code are removed, they also had no effect for the vast
majority of nodes with the default visual_scale of 1.0.
The texture continues to have it's base at ground level.
* This backend permit mods to store extra players attributes to a common interface.
* Add the obj:set_attribute(attr, value) Lua call
* Add the obj:get_attribute(attr) Lua call
Examples:
* player:set_attribute("home:home", "10,25,-78")
* player:get_attribute("default:mana")
Attributes are saved as a json in the player file in extended_attributes
key
They are saved only if a modification on the attributes occurs and loaded
when emergePlayer is called (they are attached to PlayerSAO).
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.
Desert and sandstone dungeons have 2 node wide corridors. Previously,
nodebox stairs were disabled because dungeon generation code did not
support nodebox stairs wider than 1 node, now it does.
Add 'stair desert stone' content id to MappgenBasic.
Requires 'mapgen stair desert stone' to be added to Minetest Game.
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.
The default of 15 is unchanged.
7 degrees is x10 magnification which is common for binoculars.
Alter hardcoded limits in camera.cpp:
Minimum 7 degrees.
Maximum 160 degrees to match upper limits in advanced settings.
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.
- Increase ContentFeatures serialization version
- Color property and palettes for nodes
- paramtype2 = "color", "colored facedir" or "colored wallmounted"
Previously, object meshes had their North and South faces darker than
East and West faces, the opposite of nodes and meshnodes. This commit
corrects this.
State constants as float-literals not double-literals.
Simplify code.

Fix the maths that check if any part of a mapblock or sector is over the
set map_generation_limit.
Therefore avoid the loading of any over-limit blocks that were previously
generated when map_generation_limit was larger. The set limit can vary
for a world because it is not yet a per-world mapgen parameter, even when
it is sometimes it will be changed deliberately.
Therefore avoid a player being returned to world centre if they re-enter
a world while being over-limit.
Fix the createSector() crash caused by a mob spawning over-limit in an
over-limit mapblock
* 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()).
"[sheet:WxH:X,Y" assumes the base image is a tilesheet with W*H tiles
on it and crops to the tile at position X,Y. Basically it works
like "[verticalframe" but in 2D.
For testing, I combined the four default_chest images into one.
Breath is now handled server side. Changing this behaviour required some modifications to core:
* Ignore TOSERVER_BREATH package, marking it as obsolete
* Clients doesn't send the breath to server anymore
* Use PlayerSAO pointer instead of peer_id in Server::SendPlayerBreath to prevent a useless lookup (little perf gain)
* drop a useless static_cast in emergePlayer
Remake the light_decode_table.
The table starts out without pre-filled in values since those
are always discarded by the code apparently. We calculate a
pseudo curve with gamma power function, and then apply a new
adjustment table.
The adjustment table is setup to make the default gamma of 2.2
look decent: not too dark at light level 3 or so, but too dark
at 1 and below to be playable. The curve is much smoother than
before and looks reasonable at the whole range, offering a
pleasant decay of light levels away from lights.
The `display_gamma` setting now actually does something logical:
the game is darker at values below 2.2, and brighter at values
above 2.2. At 3.0, the game is very bright, but still has a good
light scale. At 1.1 or so, the bottom 5 light levels are virtually
black, but you can still see enough detail at light levels 7-8,
so the range and spread is adequate.
I must add that my monitor is somewhat dark to begin with, since
I have a `hc` screen that doesn't dynamic range colors or try to
pull up `black` pixels for me (it is tuned for accurate color and
light levels), so this should look even better on more dynamic
display tunings.
* Calculate maximum interact distance from wielded tool
* New "interacted_while_dead" cheat_type for the Lua API
* Disallow dropping items while dead
* Move player to spawn before resurrecting them
Currently, lua does a regular exit() after a lua panic, which can make
a problem hard to debug. Invoking FATAL_ERROR() instead will print
some useful information, and abort() minetest, so that a debugger can
be used to analyze the situation.
Trying to resolve a path with RemoveRelativePathComponents that can't
be resolved without leaving leading parent components (e.g. "../worlds/foo"
or "bar/../../worlds/foo") will fail. To work around this, we leave
the relative components and simply remove the trailing components one
at a time, and bail out when we find a parent component. This will
still fail for paths like "worlds/foo/noexist/../auth.txt" (the path
before the last parent component must not exist), but this is fine
since you won't be able to open a file with a path like that anyways
(the O.S. will determine that the path doesn't exist.
Try `cat /a/../etc/passwd`).
As mgv7 is now the default mapgen i re-checked its tunnel width on request,
discovered they needed to be wider, and have made this change.
This commit widens the identical 3D noise tunnels in the other mapgens in
exactly the same way.
Fixes#4878
Also remove an artificial viewing range reduction that
(presumably) was added to compensate for miscomputed
viewing ranges, and that doesn't seem to be needed any
more (thanks to lhofhansl).
Schematics can already be placed with a param2 value, but not
simple 1-node plant decorations of the simple type.
This adds a `param2` field to the simple deco type that is
checked to be between 0 and 255, and put to the placed node
at mapgen.
This can be used to put a degrotate value in, or e.g. a fill
value for leveltype nodes, or a place_param2 value at mapgen
placement, or vary the shape of meshoptions plantlike drawtype.
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.
To avoid smaller biomes when extra biomes are added to MTGame.
The addition of bushes in MTGame grasslands makes wood resources easier
to find and less distant, so slightly larger biomes are now acceptable,
but also desirable to encourage travel and create more sense of adventure.
Floatland base terrain underside was too thin, causing excessive water
leakage through tunnels under lakes, now make it thicker.
Floatland mountain terrain had a rim 1 node thick which made it bare
stone, now make it 2 nodes thick to merge with the floatland base
terrain rim and to have a layer of biome material.
Make mountain terrain more exponentially shaped by altering the
exponent.
Remove unnecessary and potentially ugly MYMAX() applied to
n_base_height.
This combats the problem of sending the hundreds of
"creative" / "armor" or whatever detached invs that
exist on popular servers to each and every player
on join or on change of said invs.
Previously, paths like ./worlds would be resolved to /worlds since the
leading dot was considered just as irrelevant as a dot in the middle of
the path.
Position, velocity and acceleration vectors of particles are rotated
by the yaw of the parent object so that they are truly relative to it.
Clarify new attached particle spawner behavior in lua_api.txt.
Active objects that are attached to other objects are not safe
from deletion. As a result, the parent object may have a reference
to an id of a child's that no longer exists.
If at some point an attempt is made to manipulate the child,
enviromment->getActiveObject(child-id) returns NULL. Using the
NULL pointer causes the crash...
This is a slightly modified and cleaned up version of #3774 by RealBadAngel.
By sofar: Remove color change (just make it lighter) and some minor cleanups.
The client would not compute the distance from the camera to
to a mapblock correctly. The result was that blocks that were in
view (i.e. not beyond the fog limit) would not be rendered.
With the improved distance computation, a range adjustment that
existed in clientiface.cpp is no longer required.
The problem was seen while using the mobf mod package.
The problem happens when the server serializes entity attachments.
Sometimes, such attachments no longer exist. The serialization code
skips those. However, the total number of attachments was serialized
earlier. Therefore the client expects more than it gets, and logs a
serialization error.
PlayerSAO::disconnected() function was historical and remove the link between SAO and RemotePlayer session. With previous attributes linked to RemotePlayer saving was working. But now attributes are read from SAO not RemotePlayer and the current serialize function verify SAO exists to save the player attributes.
Because PlayerSAO::disconnected marks playersao for removal, only mark playerSAO for removal and let PlayerSAO::removingFromEnvironment do the correct saving behaviour and all the disconnection process instead of doing a partial removal and let the server loop doing the RemotePlayer cleanup and remove some saved attributes...
* Create UnitSAO, a common part between PlayerSAO & LuaEntitySAO

* Move m_hp from LuaEntitySAO to UnitSAO
* Use m_hp from PlayerSAO/UnitSAO instead of RemotePlayer
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
Flash alpha maximum is reduced from 180 to 127 to avoid player blindness
in combat. Flash alpha minimum is unchanged.
The 'damage_flash' value is now limited to max alpha, to avoid multiple
hits creating a huge value that causes flash to stay at maximum alpha
for a long period. Now alpha always starts to fade immediately after
taking damage.
Both problems can be seen in Minetest let's play videos.
Simplify and optimise some code.
Move static object storage force-delete message from errorstream to
warningstream.
Increase 'max objects per block' setting to 64.
Add missing spaces in warning code.
Modification of the emergeblocks internal state was not protected
by a lock, causing a race condition.
This can be reproduced by repeatedly running emergeblocks for an
already-generated section of the map (with multiple emerge threads).
* Move client list to ServerEnvironment and use RemotePlayer members instead of Player
* ClientEnvironment only use setLocalPlayer to specify the current player
* Remove ClientEnvironment dead code on player list (in fact other players are CAO not Player objects)
* Drop LocalPlayer::getPlayer(xxx) functions which aren't used.
* Improve a little bit performance by using const ref list for ClientEnvironment::getPlayerNames() & Client::getConnectedPlayerNames()
* Drop isLocal() function from (Local)Player which is not needed anymore because of previous changes
This change permits to cleanup shared client list which is very old code.
ClientEnvironment doesn't use player list anymore, it only contains the local player, as addPlayer is only called from Client constructor client side.
Clients are only CAO on client side, this cleanup permit to remove confusion about player list.
* remove IGameDef from Player class, only LocalPlayer has it now
* move many attributes/functions only used by LocalPlayer from Player to LocalPlayer
* move many attributes/functions only used by RemotePlayer from Player to RemotePlayer
* make some functions const
* hudGetHotbarSelectedImage now returns const ref
* RemotePlayer getHotbarSelectedImage now returns const ref
* various code style fixes
* ClientEnvironment now uses UNORDERED MAP for active objects
* Use RemotePlayer and LocalPlayer everywhere it's possible
* Minor code style fixes
* Drop Client::getBreath() unused function
* Server/Client Environments now have an helper to cast Player object in the right type to use it
* Server: use RemotePlayer everywhere and remove previous added casts
* Client: use LocalPlayer where needed
* Environment: remove unused functions (getPlayers(), getRandomConnectedPlayer(), getNearestConnectedPlayer())
* LocalPlayer take ownership of maxHudId as it's the only caller
* RemotePlayer take ownership of day night ratio as it's the only user
* Pass getPlayerControl as const reference to prevent object copy on each call (perf improvement in ObjectRef::l_get_player_control call)
* getPlayerSAO is now only RemotePlayer call
* get/setHotbarItemCount is now RemotePlayer owned
* Server: Use RemotePlayer instead of Player object on concerned call to properly fix the object type
* PlayerSAO now uses RemotePlayer instead of Player because it's only server side
* ObjectRef::getplayer also returns RemotePlayer as it's linked with PlayerSAO
The initial problem was that mutex_auto_lock.h tries to use std::unique_lock<std::mutex>
despite mutex.h not using C++11's std::mutex on Windows. The problem here is the mismatch
between C++11 usage conditions of the two headers. This commit moves the decision logic
to threads.h and makes sure mutex.h, mutex_auto_lock.h and event.h all use the same features.
This is part 2 for 5f084cd98d7b3326b51320455364337539710efd
Other improvements:
* Use the defined ItemGroupList when used
* make Client::checkPrivilege const
* inline some trivial functions
* Add ActiveObjectMap typedef
* Add SettingsEntries typedef
'getSpawnLevelAtPoint()' did not account for disabled mountains, it

Rebased and tuned version of Calinou's original pull request.
'm_view_bobbing_speed' controls the frequency of view bobbing,
hand bobbing and footsteps, it was limited to a maximum of 40 (walking
frequency) so did not increase if player speed was modified by a
'speed buff', a sprinting mod or modified in .conf or advanced
settngs.
This commit raises the limit to 70 which is suitable for sprinting.
Adds several new ways that the plantlike drawtype mesh can be changed.
This requires paramtype2 = "meshoptions" to be set in the node
definition. The drawtype for these nodes should be "plantlike".
These modifications are all done using param2. This field is now
a complex bitfield that allows some or more of the combinations to
be chosen, and the mesh draw code will choose the options based as
neeeded for each plantlike node.
bit layout:
bits 0, 1 and 2 (values 0x1 through 0x7) are for choosing the plant
mesh shape:
0 - ordinary plantlike plant ("x" shaped)
1 - ordinary plant, but rotated 45 degrees ("+" shaped)
2 - a plant with 3 faces ("*" shaped)
3 - a plant with 4 faces ("#" shaped)
4 - a plant with 4 faces ("#" shaped, leaning outwards)
5 through 7 are unused and reserved for future mesh shapes.
bit 3 (0x8) causes the plant to be randomly offset in the x,z
plane. The plant should fall within the 1x1x1 nodebox if regularly
sized.
bit 4 (0x10) causes the plant mesh to grow by sqrt(2), and will cause
the plant mesh to fill out 1x1x1, and appear slightly larger. Texture
makers will want to make their plant texture 23x16 pixels to have the
best visual fit in 1x1x1 size.
bit 5 (0x20) causes each face of the plant to have a slight negative
Y offset in position, descending up to 0.125 downwards into the node
below. Because this is per face, this causes the plant model to be
less symmetric.
bit 6 (0x40) through bit 7 (0x80) are unused and reserved for
future use.

Disable the ability to connect to old servers by default to
improve password security.
If people still want to connect to old (0.4.12 and earlier)
servers, they can flip the send_pre_v25_init setting.
Add the ability to detect if we've tried to connect
to a server which only supports the pre v25 init protocol,
and show an apropriate error message. Most times the error
will already be catched at the serverlist level, the
detection mechanism only acts as last resort, because the
"Connection timed out" error message that would be shown
otherwise would be very confusing.
Automatic "fixing" of this condition is not desired,
as it would allow for downgrade attacks.
As already 161 of the 167 servers on the serverlist
support the new srp based auth protocol (> 96%),
the breakage should be minimal.
Follow up of commit
af30183124d40a969040d7de4b3a487feec466e4 "Add option to not send pre v25 init packet"
Also change the pessimistic assumption of masterlist
server versions to optimistic, in order to avoid buggy
behaviour (favourites not in the serverlist would be
denied to connect to, etc).
Fixes#4446: a syntax error that happens if something else (such as
<iomanip> or <locale> in certain libstdc++ versions) includes
<libintl.h> later, which contains a function declaration for gettext
that gets mangled by the macro.
See the added comment in gettext.h and the discussion in #4446/#4452
for details.
If compiling according to a C++ version before C++11, then define
std::to_string ourselves.
Add a to_wstring version as well
As std::to_string() for floating point types uses %.6f as floating
point format converter, instead of %G, it needs special care.
To preserve ftos() behavior (which is expected to use the %G format
converter), it no longer uses to_string().
If a mod is disabled, or upgraded without sufficient backward compatibility,
then entities it has put into the world become unknown, and continue moving
around, but are completely unrecognisable.
This change allows the player to see their type, and therefore which mod is
or was responsible.
previously function used tonumber which returned float
this caused errors in large numbers and resulted in
obj-def-handlers being invalid when retrived from lua tables in c
* Move included json code to jsoncpp subdirectory
This is needed to avoid having to specify the minetest src directory
as a system include when fixing the json includes.
* Fix json includes
They used "", so that the compiler searches the project's directory
first. The result was that when compiling with a system jsoncpp,
the project's own version of json.h was still included, instead of
the system version.
The includes now use <>, so a system location, or one specified with
'-Ilocation' is searched only.
* Fix for jsoncpp deprecated function warning
When compiling with a newer version of jsoncpp (and
ENABLE_SYSTEM_JSONCPP=true), jsoncpp emits a warning
about a deprecated function that minetest uses.
This fallback to std::map & std::set for older compilers
Use UNORDERED_SET as an example in decoration and ore biome sets

Fix height check comparison from '>=' to '>'.
Fix getHeight() for schematic decorations to account for
'deco place center y' flag and for how normal placement
sinks schematic 1 node into the ground.
Jungletrees were not being placed at y = 46, y = 47 despite
having an acceptable 16 nodes of height above ground surface.
When the 'flat' and 'trees' flags were moved into mgv6_spflags they
were left in mg_flags in an attempt to support old mgv6 worlds. However
their appearence in mg_flags causes confusion, also, later, old-world
support was found to be broken for mgv6 worlds with 'notrees'.
This commit cleans up the mess and comes a month after a thread warning
of the change, and explaining the required action, was posted in the
news subforum. Only old mgv6 worlds with 'flat' or 'notrees' are
affected, a small minority of worlds, the required action being
correctly setting these flags in mgv6_spflags.
Disable a section of the 'map settings manager' unit test which is to

The "testStartStopWait" unit test is unreliably failing on mac,
for some time already. See bug #3786.
Having the unittest fail unreliably doesn't help anybody but mostly
inhibits the main feature of travis builds: to test PRs for regressions.
Therefore, disable the specific unit test for until bug #3786
is fixed.
The source used a hodge-podge of different combinations of different
macros to check for linux: 'linux', '__linux', '__linux__'.
As '__linux__' is standard (Posix), and the others are not, the source
now uniformly uses __linux__. If either linux or __linux are defined,
it is made sure that __linux__ is defined as well.
It seems that various different devices register as
Joysticks on linux, and their presence has caused
lots of confusion amongst minetest users.
Therefore, disable the joystick feature.

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.
- Move mapgen creation logic out of EmergeManager and into Mapgen
- Internally represent mapgen type as an enum value, instead of a string
- Remove the need for a MapgenFactory per mapgen
Reduce spread from 96 to primes 61 and 67 (either side of 64)
Prime spreads help to keep 3D noise periodic features unaligned
'cave width' 0.2 to preserve tunnel width
Reduce octaves to 3 to improve network structure
- 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.
Add new colours 'skycolour_bright_night', 'bgcolour_bright_night'
and enable these between sunset end and sunrise start
Night sky has same hue as day sky but is darker and more saturated
Night horizon haze (bgcolour) is slightly less saturated and
slightly brighter than night sky, to be consistent with daytime
horizon haze
Mgvalleys: Remove riverbed sand placement from base terrain generation
Riverbed material placement moved to MapgenBasic::generateBiomes()
Document fields and add note that the biome API is still unstable
- Adds only ~100 nodes per chunk to trans_liquid with similar processing time
- Adds liquid nodes themselves instead of potential solid nodes below them
- CONTENT_IGNORE nodes are interpreted as if they continue their neighborhood
- This allows liquid columns to span multiple chunks without being interrupted
- NOTE: Expects an one-node border in generation chunk without liquid changes
Previously, rivers were sometimes blocked by vertical walls
of mountain terrain due to river carving being disabled
when base terrain height was below water_level - 16
Remove now unused base terrain heightmap created in
generateTerrain()
Gives a convenient way to check a player's password.
This entirely bypasses the SRP protocol, so should be used
with great care.
This function is not intended to be used
in-game, but solely by external protocols, where no
authentication of the minetest engine is provided, and
also only for protocols, in which the user already gives the
server the plaintext password.
Examples for good use are the classical http form, or irc,
an example for a bad use is a password change dialog inside
formspec.
Users should be aware that they lose the advantages of the SRP
protocol if they enter their passwords for servers outside the
normal entry box, like in in-game formspec menus,
or through irc /msg s,
This patch also fixes an auth.h mistake which has mixed up the
order of params inside the decode_srp_verifier_and_salt function.

Adds the particle option `collision_removal = bool`
Some particles are hard to use right now since they either go through
solid blocks (without collision detection), and with collision
detection enabled they (e.g. raindrops) would just stop dead on the
floor and sit there until they expire, or worse, scrape along a wall
or ceiling.
We can solve the problem by adding a boolean flag that tells the
particle to be removed if it ever collides with something. This will
make it easier to add rain that doesn't fall through your roof or stick
on the top of it. Or clouds and smoke that don't go through trees.
Particles that collide with this flag are marked expired
unconditionally, causing them to be treated like normal expired
particles and cleaned up normally.
Documentation is adjusted accordingly.
An added bonus of this patch is that particles can potentially collide
many times with nodes, and this reduces the amount of collisions to 1
(max), which may end up reducing particle load on the client.
This commit moves noise calculation to the functions where the noise is
actually required, increasing the separation of concerns and level of
interdependency for each mapgen method. Valleys Mapgen is left unmodified.
- Convert instances of numeric literal doubles to floats
- Move dswitchint to a local variable now that being a member is unnecessary
- Improve const correctness
- Indentation fixes
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.
BiomeGen defines an interface that, given a set of BiomeParams, computes biomes
for a given area using the algorithm implemented by that specific BiomeGen.
This abstracts away the old system where each mapgen supplied the noises
required for biome generation.
We can remove the function in MtNativeActivity now
as it serves precisely that purpose: to tell irrlicht
that we handled the esc key.
TODO for later:
* Perhaps try to find a more performant container than KeyList
Fixes a bug where packet reordering made the server give the
client two peer ids instead of one. This in turn confused
reliable packet sending and made connecting to the server fail.
The client usually sends three packets at init: one "dummy"
packet consisting of two 0 bytes, and the init packet as well as
its legacy counterpart. The last one can be turned off since commit
af30183124d40a969040d7de4b3a487feec466e4, but this is of lower
relevance for the bug. The relevant part here is that network
packet reorder (which is a normal occurence) can make the packets
reach the server in different order.
If reorder puts the dummy packet further behind, the following
would happen before the patch:
1. The server will get one of the init packets on channel 1 and
assign the client a peer id, as the packet will have zero as
peer id.
2. The server sends a CONTROLTYPE_SET_PEER_ID packet to inform
the client of the peer id.
3. The next packet from the client will contain the peer id set by
the server.
4. The server sets the m_has_sent_with_id member for the client's
peer structure to true.
5. Now the dummy packet arrives. It has a peer id of zero, therefore
the server searches whether it already has a peer id for the
address the packet was sent from. The search fails because
m_has_sent_with_id was set to true and the server only searched
for peers with m_has_sent_with_id set to false.
6. In a working setup, the server would assign the dummy packet to
the correct peer id. However the server instead now assigns a
second peer id and peer structure to the peer, and assign the
packet to that new peer.
7. In order to inform the peer of its peer id, the server sends a
CONTROLTYPE_SET_PEER_ID command packet, reliably, to the peer.
This packet uses the new peer id.
8. The client sends an ack to that packet, not with the new peer id
but with the peer id sent in 2.
9. This packet reaches the server, but it drops the ACK as the peer
id does not map to any un-ACK-ed packets with that seqnum. The
same time, the server still waits for an ACK with the new peer
id, which of course won't come. This causes the server to
periodically re-try sending that packet, and the client ACKing it
each time.
Steps 7-9 cause annoyances and erroneous output, but don't cause
the connection failure itself.
The actual mistake that causes the connection failure happens in 6:
The server does not assign the dummy packet to the correct peer, but
to a newly created one.
Therefore, all further packets sent by the client on channel 0 are
now buffered by the server as it waits for the dummy packet to reach
the peer, which of course doesn't happen as the server assigned
that packet to the second peer it created for the client.
This makes the connection code indefinitely buffer the
TOSERVER_CLIENT_READY packet, not passing it to higher level code,
which stalls the continuation of the further init process
indefinitely and causes the actual bug.
Maybe this can be caused by reordered init packets as well, the only
studied case was where network has reliably reordered the dummy
packet to get sent after the init packets.
The patch fixes the bug by not ignoring peers where
m_has_sent_with_id has been set anymore. The other changes of the
patch are just cleanups of unused methods and fields and additional
explanatory comments.
One could think of alternate ways to fix the bug:
* The client could simply take the new peer id and continue
communicating with that. This is however worse than the fix as
it requires the peer id set command to be sent reliably (which
currently happens, but it cant be changed anymore). Also, such a
change would require both server and client to be patched in order
for the bug to be fixed, as right now the client ignores peer id
set commands after the peer id is different from
PEER_ID_INEXISTENT and the server requires modification too to
change the peer id internally.
And, most importantly, right now we guarantee higher level server
code that the peer id for a certain peer does not change. This
guarantee would have to be broken, and it would require much
larger changes to the server than this patch means.
* One could stop sending the dummy packet. One may be unsure whether
this is a good idea, as the meaning of the dummy packet is not
known (it might be there for something important), and as it is
possible that the init packets may cause this problem as well
(although it may be possible too that they can't cause this).
Thanks to @auouymous who had originally reported this bug and who
has helped patiently in finding its cause.
Version 1.8.2 of irrlicht changed the way that IGUIStaticText::getTextHeight() works and since that release properly deals with newlines.
From irrlicht changes.txt for 1.8.2, "IGUIStaticText::getTextHeight returns now the correct height for texts with newlines even WordWrap is not set."
* Remove the copy from db::loadBlock by using a pointer to the destination

The path finding code works fairly well except that it considers
anythin not CONTENT_AIR to be "above the surface". This results in
paths that are unwalkable for entities since e.g. plants are not
walkable. The path would force them to jump on top of grass plants,
etc..
The obvious solution is not to use CONTENT_AIR as a criteria, but
instead distinguish between walkable and non-walkable nodes. This
results in paths that properly walk through grass nodes.
This was extensively tested by a flock of electric sheep.
Note that for underwater purposes this changes the behaviour from
"the surface is walkable" to "ignore water entirely" making the
path go across the water bottom, and pathing fail likely from the
water surface. This is intentional.
Before, the GridNodes were stored in vector<vector<vector<T>>>,
and initialized in advance. Putting three vectors inside each other
puts lots of unneccessary stress onto the allocator, costs more memory,
and has worse cache locality than a flat vector<T>.
For larger search distances, an the array getting initialized means
essentially O(distance^3) complexity in both time and memory,
which makes the current path search a joke. In order to really
profit from the dijkstra/A* algorithms, other data structures
need to be used for larger distances.
For shorter distances, a map based GridNode storage may be slow as
it requires lots of levels of indirection, which is bad for things like
cache locality, and an array based storage may be faster.
This commit does:
1. remove the vector<vector<vector<T>>> based GridNodes storage that
is allocated and initialized in advance and for the whole
possible area.
2. Add a vector<T> based GridNodes storage that is allocated and
initialized in advance for the whole possible area.
3. Add a map<P,T> based GridNodes storage whose elements are
allocated and initialized, when the path search code
demands it.
4. Add code to decide between approach 2 and 3,
based on the length of the path.
5. Remove the unused "surfaces" member of the PathGridnode class.
Setting this isn't as easy anymore for the
map based GridNodes storage.
* Fix naming style for methods and classes:
Use camelCase for methods and PascalCase for classes as
code style demands it. And use sneak_case for methods that
are not member of a class.
* Replace "* " with " *" for Pointers
* Same for references
* Put function body opening braces on new line
* Other misc minor non functional style improvements
There is no need to put them into the header, they are solely used
inside the pathfinder.
Another advantage of this change is that only the pathfinder.cpp has
to be compiled if PATHFINDER_DEBUG gets defined or undefined, not
all files including the .h.
This commit moves the pathfinder classes to the cpp file without
modifications.
Also, the PATHFINDER_DEBUG macro gets moved to the cpp file and
the PATHFINDER_CALC_TIME macro gets moved to a plce where it
actually does work.
Previously, race conditions occurred inside logging, that caused
segfaults because a thread was trying to use an old pointer that
was freed when the string was reallocated. Using a fixed-length buffer
avoids this, at the cost of cutting too long messages over seveal lines.
The shadow bug at y = 63 was caused by dark air being placed as dust,
when the biome dust was unspecified it was falling back to 'air'
In dustTopNodes only dust == 'ignore' will disable dust placement
Previous mountain terrain generation was by necessity placing
stone in air, this was removing air from any overgenerated
structures such as tunnels, dungeons and large caves
Moving it into the base terrain generation loop ensures that
only 'ignore' is replaced
