Use 128px textures with a slight blur to reduce distortion caused
by formspec texture scaling.
Cross is shifted slightly up and left to compensate for formspec
button image shift.
In survival mode, zoom is disabled, the binoculars item is needed to
allow a zoom with a 10 degree FOV, realistic for compact binoculars.
Creative mode or per-player creative privilege allows a zoom with a
15 degree field of view (the default MT engine zoom FOV).
Adds a direct resource of green dye, and a flower resource of black dye.
Completes the colour sequence: red, orange, yellow, green, blue, violet.
Makes all base dyes cultivatable and sustainable, without the presence
of coal.
Add the new flowers to the world with the same density variation as the
others, but obviously with different noise seeds. Results in more flowers
in a world and more variety of flower combinations.
Previously, body and limbs were stretched vertically by 1.125, creating
rectangular pixels on side faces. Head was unstretched.
Remove stretch of body and limbs, leaving the head unchanged.
No other change would excessively shorten the model, so also scale up
the model slightly, by * 1.05, such that the reduction factor for height is
equal to the increasing factor for width. This minimises the changes to
height and width.
Remove cape support.
Update the collisionbox to match.
Add missing license.txt.

Add and use 'default.node_sound_snow_defaults()' function.
Some files or editors may use \r instand of \n like notepad++. If you copy
text written in notepad++ and pasted into the book. The book will only have
one page.
Uses the new player object property 'can zoom'.
In survival mode, use of zoom requires the binoculars item in
inventory.
Zoom is automatically allowed in creative mode and for players with
the 'creative' privilege.
The binoculars.update_player_property() function is global so can be
redefined by a mod for alternative behaviour.
In survival mode, use of the minimap requires the mapping kit item.
Minimap radar mode is always disabled in survival mode.
Minimap and minimap radar mode will be automatically enabled in creative mode
and for any player with the 'creative' privilege.
The 'map.update_hud_flags()' function is global so can be redefined by a mod for
alternative behaviour.
Make deeper, to compensate for ease of travel using 3D noise tunnels.
Make depth more progressive with value:
Ore, upper limit
Coal 64 no change
Iron 0 no change
Tin -32 > -64
Copper -16 > -128
Gold -64 > -256
Diamond -128 > -512
Mese crystal -64 > -512
Mese block -1024 no change
Make y of 1st density increase deeper but following a similar logic to before:
Ore, upper limit
Coal 0 no change
Iron -64 no change
Tin -128 no change
Copper -64 > -256
Gold -256 > -1024
Diamond -256 > -1024
Mese crystal -256 > -1024
Mese block -2048 new
Add second, denser layer of mese blocks with a decrease of separation and
increase in density equal to mese ore layers.
The tnt:boom node doesn't actually need the on_construct and on_timer functions to remove the node after 0.4 seconds as the tnt_explode function already does this beforehand.
Liquids that are 'igniters', such as lava, will drop the torch without
a flame-extinguish sound, as the torch item will burn up after a few
seconds with a sound and smoke particles.
All other liquids cause a flame-extinguish sound.
Only register floatland biomes if mgv7 'biomerepeat' flag is false.
Simplify floatland biomes to coniferous forest and ocean.
Make 'mgv7_floatland_level' and 'mgv7_shadow_limit' parameters global
values for mods to use to register their own floatland biomes.
Previous times were chosen using statistical maths, but reports suggested
this was too long.
I tested by timing an ABM acting on 100 nodes, with interval and chance equal
to the old sapling ABM.
50 at 4m59s.
99 at 24m58s.
100 at 26m58s.
So choose a grow time between 5 and 25 min for tree and bush saplings.
If 'can grow' is false at grow time the timer is reset to 5 min.
This allows us to preserve mgv6 ore distribution while giving us the freedom
to alter ore distribution for other mapgens.
Other mapgens are larger scale and have 3D noise tunnels which make vertical
travel easier, so ores can be deeper.
Other mapgens have registered biomes which allows us to limit ores to certain
biomes.
It is useful for protection mods to know who owns an exploding
TNT block. This allows the blocks destroyed by the TNT to be
limited to the same ones the owner could destroy without using
TNT.
TNT placed within a protected area by the area owner, and later
ignited by another player will destroy within the protected area
nodes the igniter may not otherwise be able to interact with. Any
player could significantly increase the size of an explosion by
placing more TNT in an adjacent unprotected area if the original
TNT block was placed withing 1 node of such a boundary. This
feature sounds dangerous, but we are talking about TNT. Players
should use it carefully.
If backface culling is not specified for a tile in 'images' it is set to true.
Slabs already have backface culling due to being defined as nodeboxes (which
are then converted to meshnodes).
Really large books just waste hard drive space and the engine is not designed to
handle that much data in item metadata, this can cause strange things to happen.
No longer have 2 recipes for stairs, choose the one that matches the appearence
in inventory (stair rising toward the right).
Helps to reduce recipe count now that an increasing number of stairs are
being registered.
Alter the wooden trapdoor side texture, replacing the white area with a
repetition of the wood pixels.
It is now consistent with the steel trapdoor side texture.
This keeps the filenames the same, but adds a new "inside" double texture
for the open chest.
Use regular drawtype for closed chest and delete the "cube.obj" model.
X-flip the right-side texture for the closed chest.
Revert the new 'default:game' inventory back to the old 'main' and use the
lbm to restore the contents of the chest.
Change the name of the conversion LBM to ensure it is run again on already
converted chests.
Adds a mesh model that appears when a chest is opened. The chest
stays visibly open as long as the player keeps it open. When the
player closes the formspec, the chest returns back to the closed
shape. While opening and closing, a sound plays.
A second person inspecting the chest will trigger a second sound
open. However, only after the last player closes the chest, does the
chest actually visually close and is the sound close played. This
keeps mesh updates to a minimum.
While it's possible that a server shutting down may cause chests
to remain open, this does not affect the chests' working matter,
and opening or closing them should fix them.
Old chests are converted to the new style by LBM. I previously
had them converted on open but this was unreliable, and LBMs
don't have that problem.
Open chests cannot be dug up. This prevents people from keeping
a chest open and digging it out as well, since closing a chest
would place a chest back (swap) at the spot. We could protect
against this, but it still messes up the client and causes a lot
of "missing node inventory" error messages otherwise. It's
unlikely but possible that a player lagging out causes a chest
to stay "open" and thus unremovable by digging, but there are
other ways of dealing with that - a server restart fixes that
issue.
If the lid of the chest is obstructed, the sounds continue to play,
but the lid isn't opened. Obstructed means that a node is present
above the chest lid, however, we ignore several node types like signs,
torches (not 3d) and wallmounted nodeboxes (typically signs) since
they don't pose any major obstruction in almost any case, and are
typically found above chests. Additionally, the selection box of the
opened chest does not include the lid, and so one can still interact
with e.g. a sign behind an open lid.
Due to the fact that chests now have 7+ textures, we can no longer
use materials (limit: 6) to texture the chest, and so there is now
a single UV mapped image that applies both to open and closed chests.
While this does mean texture pack makers need to create it, this
is extremely simple and consists of a simple cut'n'paste over the
template and should be really easy to do. Only one texture file is
now then used for both open and closed chests.
Previously i had matched ore density to moreores, but this density was
too high and out of balance with MTGame, reduce density to be similar
to copper ore.
The 2 levels of underground ore were overlapping, fix.
Textures are actually by kilbith, update credits.
Also credit kilbith for bronze, copper, gold and steel blocks, credits
had not been updated at the time.
Use Calinou's textures from moreores mod.
Craft bronze from tin and copper instead of steel and copper.
Match ore density to the moreores mod but start ore at a depth of
y = -32 to be part of the depth progression of other ores.
Allow skeleton keys to be stacked by converting them to craftitems and
adding a few lines of code to add a new itemstack to the inventory with
the new key or drop it at the player position if the inventory is full.
Bush saplings grow in half the time of tree saplings.
Bushes do not need 'from sapling' schematic variants because only the
stem node is force-placed in the mapgen schematic, so only the sapling
is force-replaced.
Bush leaves drop saplings with a rarity that ensures at least 1 sapling
per bush on average.
Slabs are placed horizontal instead of vertical, even if they are
placed on a wall.
Slabs are rotated automatically if they are placed to another slab,
no matter which material.
Slabs are placed at the lower position if the placer points into
the lower half of the pointed node and to the upper position if
pointed to the upper half.
Stairs are placed normal if the placer points to the lower half of
the pointed node and rotated upside down if pointed to the upper half.
As part of making vertical travel easier to reduce reliance on
sneak ladders.
Calculate using cubic pixels of steel.
A steelblock is 16^3 = 4096 cubic pixels steel.
6 ingots is 6/9 steelblocks.
A rail is a 2*2*16 pixel length of steel, 64 cubic pixels steel.
6 ingots produces 2*21 rails = 21 rail nodes.
Choose 18 for an even number that is a multiple of ingot number.
Replace the stick with 2 wood in the recipe to be closer to the amount
of wood that would be needed for 20*4 sleepers.
Replace 2 mese crystal fragments with 1 mese crystal to
compensate for the larger number of nodes returned. The result
is the recipe is much more generous with steel usage but slightly
less generous with mese usage, keeping power rail cost reasonably high.
Replace 2 coal lumps with 1 for a similar recipe to power rails.
Flora is converted to dry shrub in desert sand and silver sand.
No conversion in sand to preserve sand dune grasses.
Dry shrubs do not spread so this conversion, used by players, is the
only way to generate them.
Replace possibly trademarked artwork with royalty free and
OK for commercial use artwork.
The Pup appears by default but does not alias the Nyan Cat nodes
away. For that you will have to enable the setting. A settingtypes.txt
is provided to make that really easy. This allows people to get
an out-of-tree mod and not have their Nyan nodes disappear.
The mod can also be disabled entirely this way for those who don't
want it.
There's some eatser eggs in here as well. Instead of making the
nodes burnable, they are edible, and make you bark and howl. And
perhaps something else too.
If there is no group:soil node found below, do not replace flora with
dry shrub, this was breaking flower pots and other mods.
Originally, flora would only turn to dry shrub if in desert sand.
Use the soil group more instead of checking for multiple node names.
Remove 'neighbors' from ABM.
Turn any flora to dry shrub if on a non-soil, except when on default:sand
to avoid dune grasses being replaced.
Search for "group:soil" when searching for a position for the new flora
node, instead of searching for multiple node names, however do not spread
flora onto desert sand, which is in the soil group.
Remove default:dirt_with_snow from the soil group as it would be frozen
soil. It can be dug and placed to turn it into dirt (consider this some
extra work needed to make it cultivatable).
Commit c68b8274fe prevented books from
being copied in the crafting grid, and made it so that old books, though
seemingly successfully transferred to the new format, could not be written
to as the old data still persisted.
- Allow rotation of wallmounted nodeboxes (signs) since they are
now rotating properly.
- Instead of testing `ndef` several times, do it once, correctly.
- Simplify exception logic for nodes that have `on_rotate` set.
- For simplicity, return itemstack, always.
- Remove a useless nil check.
Previously you could place junglegrass on dirt to convert that dirt to
dirt_with_grass, but this is unsuitable now that rainforest has a
surface of dirt_with_rainforest_litter.
Remove junglegrass from the 'grass' group.
Since meta secret field is blank on any keys (default:key) obtained using
/give, the game will crash if you attempt to use one of these. This follows
along the principle that the game should never have any reason to crash.
A simple set of biomes for now: Ocean, coniferous forest, grassland,
sandstone desert.
Update biome lists for blob ores and decorations.
Make sandstone desert filler 1 node deeper to match other deserts.
Instead of right click, the skeleton key is now a true `tool`
in the sense that it's default left-click action is to create
a key for the locked object.
This is far better than the outcome of the patches we've done
where the only way to create a key for a locked item was to
use sneak+rightclick. Now keys are perhaps a bit more sensible,
left for making keys, right for opening stuff with keys.
Fixes#1625
Allows rotating things like signs and torches. Axis rotation
rotates over all 6 faces, face rotation flips upside down to
flat on floor only, and of course in the 4 horizontal directions.
Made the code a bit more modular to account for different rotation
schemes. Should be easier to extend from here on to other needs,
and the functions can be reused by other mods for convenience.
Usage and tool break sounds were played at 'pointed_thing.above' which
can be nil if not pointing at anything or at an entity. This caused
sounds to be played to all players on a server non-positionally.
Fallback to player pos for sounds if 'pointed_thing.above' is nil.
Replace 'pt' variable with 'pointed_thing' in 'register_tool'.
Currently jungletrees and junglegrass use sidelen 80 for simplicity,
but this results in a more uneven distribution of decorations. A more
even distribution helps keep rainforest darker with a more unbroken
canopy.
This is also more consistent. 80 is based on the default mapchunk
size, all other decorations use sidelen 16 or smaller to divide into
any mapchunk size.
Denser jungletree for darker rainforest:
Highest 'jungletree' nodes now prob 255.
Add a 5th lower branch layer.
Increase lower branch layer y-slice prob to 191.
Aspen:
Extend trunk upwards by 1 node to reduce leafdecay radius to 2.
Pine:
Make lower trunk 1 node longer so that lowest branches are more often
higher off the ground, also to make pines taller.
Appletree:
Make 2 opposite branches prob 255, the other 2 prob 127, to avoid
trees with 1 or 0 branches. Therefore also add random rotation.
Increase to 5 ladders from 7 sticks.
More generous to help with vertical travel.
Divide the log core volume of 14 * 14 * 16 cubic pixels by the volume of
a ladder node with two 2 * 2 * 16 side pieces and four 2 * 1 * 16 rungs
(cut down to length 14), to get 12.25 ladders per log.
The recipe of 7 stick items is 7 / 16 = 0.4375 logs.
Ladders per 7 stick items = 0.4375 * 12.25 = 5.36.
Utilizes the new key-meta (as with nodes) and the ability to set the description of an itemstack with the `description` meta key. Includes code to convert old metadata to new key-meta.
- beds
- boats
- carts
- key/skeleton key
- seeds
All these had on_place handlers that did not allow nodes with
an on_rightclick() handler to be used first (if not using
sneak). This code is taken from the torches mod and applied
everywhere.
This allows all these items to e.g. be inserted into the `frame`
mod's item frames.
Utilizes several new features allowing the description of an item to be changed using the `description` meta key. This also moves keys from using the old single-value itemstack metadata system to the new node-like metadata system.
Return to previous parameters interval = 1, chance = 2.
Compensates for the increase in default active block radius.
Large amounts of lava cooling at once is known to overload sound
creation, producing error messages.
As part of the original plan for a new lightcurve.
With the old lightcurve lights were so dim all light sources had light
source level 13 or 14 to compensate, resulting in almost no difference
between torchlight and a maximum brightness light.
The new lightcurve makes all light sources effectively much brighter by
spreading visually-bright light further, torches are now slightly too
bright. So now we can reduce the light source level of torches while
actually making them effectively brighter than with the old lightcurve.
This also creates a desirable difference between torchlight and a
maximum-brightness light source.
This implements a node-timer based leafdecay mechanism, and exposes
an API to use it in mods.
The API is documented in game_api.txt.
`default.register_leafdecay(leafdecaydef)`
`leafdecaydef` is a table, with following members:
{
trunks = { "default:tree"}, -- nodes considered trunks
leaves = { "default:leaves", "default:apple"}, -- nodes considered leaves
radius = 3, -- activates leafdecay this far from the trunk
}
The algorithm will drop `leaves` items in the area if no `trunks` are found
in the `trunk_radius` sized area around the position of the leaf. If a node
listed in `leaves` has a group `leafdecay_drop > 0`, then the item is dropped,
otherwise the item is removed but not dropped.
The algorithm also implements a value `default.leafdecay_speed` (default
15) which can be modified to increase or decrease of the leaf decay. The
algorithm will vary the actual speed a bit to introduce randomness.
Leaf decay is randomized by 0.1 seconds to reduce the chance that
decay happens many times on the same second interval. This requires
nodetimer_interval to be set to values lower than 1.0 to have an
effect.
The leaves will decay between 2 and 10 seconds after digging the trunk,
and happen at non-integer second intervals.
-- The API was added by sofar.
Plantlike drawtype no longer applies 'visual scale' twice, so now we
use the actual scale factor desired.
Remove unnecessary 'visual_scale = 1.0' lines.
Light level 14 to be able to grow plants.
3 returned from crafting with 1 glass node, 3 mese crystals and 1
wood plank.
Seamlessly placable on appletree wood fence posts.
Now that biomes are being specified for blob ores we need a separate
set of blob ore registrations for mgv6 which has no Biome API biomes
defined.
Various minor improvements to mapgen.lua.
Now that the missing 'default_dig_snappy' sound has been added we can
remove the dirt dig sound from the table. All nodes that use the
leaves defaults table have group 'snappy' so 'default_dig_snappy' now
becomes their default dig sound.
This reverts commit 5e4a6e8ac6, and
commit 60cf3f85b6.
The original door API rewrite I posted had all rotation disabled using
the correct on_rotate() handler returning `false`. Two subsequent
changes attempting first to enable simple rotation and second disabling
that again changed the callback handler to a boolean `false`, which
is incorrect use in the screwdriver API, and actually allows rotation.
The proper way to disable rotation for facedir nodes it to use a full
callback handler that does `return false`.
TNT removes flammable nodes from the destruction radius and should
remove flames within it too because they lose their fuel and would
be removed by ABM later anyway.
Create a simple triplet table (src1, src2, dst) for all the dye
recipes and group them logically, with a bit of explanation where
they actually come from.
This prunes a lot of recipes from the list, but the old list had a
ton of combinations that did not make any sense, as well as recipes
that were just gross approximations and duplicates, mixing the same
color with itself just to get the same color back, which just wastes
packets at logon.
The list has been checked to allow all colors created from the basic
dyes (flowers+coal) so that all colors can be crafted.
Craft 4 default:sand to default:sandstone.
Previously, 4 group:sand was craftable to sandstone and sandstone was
craftable back into default:sand, allowing silver and desert sands to
be converted into incorrect colour sandstone and yellow sand.
I recently made glass footstep and dig gains too low, raise slightly.
Change dirt dug gain from above-maximum 1.5 to maximum 1.0.
Reduce gain of footsteps: stone, dirt, gravel, wood, metal
Raise gain of leaves footstep.
Some nodes with the snappy group (wool, glass pane, seeds) were missing
sound when dug with a sword.
Adding the sound causes it to be used for glass pane, so define a 'dig'
sound in the 'node sound glass defaults' table, use the footstep sound.
Adding the sound also causes it to be used for seeds which deliberately
have no dig sound, so add an empty sound override for seed dig.
Reduce the gain of the glass footstep sound which was excessively loud.
Add some freesound members to license.txt.
Handbrake was barely noticeable and fairly useless.
Equalisng with brake rail deceleration makes it more intuitive to use
and easier to judge stopping distance.
Previous code:
Used looped sounds without attaching them to objects or playing direct
to players.
The looped sounds are not 'stopped' when players leave the area.
These may be causing the bug where sounds are heard at extreme
distances.
Entering a world with already present flames results in silent flames.
Sounds are often played at a large number of points in a 6 node lattice.
A large fire is reported to cause a high load, disabling the sound code
is reported to help this.
New code:
Optional flame sound to not interfere with ambience mods.
Permanent flame now has sound.
For multiple flames, sound is positioned at the centre of all flames, and
has volume determined by flame number.
The original freesound 'large fire' recording was used to create 3 sounds
that play at random for a non-repetitive effect. At low volume it is
suitable for small fires.
Original sound files and sound function (as an empty function) kept
temporarily to reduce disruption.
Reduce gain of flame extinguish sound.
Some GPUs cause visual bugs when mip-mapping is used with indexed textures
that use alpha. Because leaves are sometimes rendered opaque it is even
more important to keep these as RGBA to preserve the correct background
colour.
Papyrus:
Make base node dirt instead of dirt_with_grass. Formerly the exposed
dirt would change to grass but the new grass spread ABM now prevents that.
Waterlily:
Don't specify a water_source node in the schematic, as it may be used in
river water. It was not force-placed but should really be "air" prob = 0.
This changes the farming API such that any nodedef with paramtype2
and place_param2 are passed through to all the plant stages of the
farming plant.
This allows plants to use an alternative mesh for the plantlike
drawtype, and provide a bit of graphical variation in plants.
We enable this for wheat, using place_param2 = 3, which is the '#'
shaped plant mesh. If you would actually be able to give yourself
this plant in creative or through /give, you would also get the
same '#' shape.
Biomes:
Add 'sandstone desert', 'cold desert', 'snowy grassland'.
Rename 'glacier' biome to 'icesheet' biome.
Rename non-swamp 'swamp' biomes to 'shore' biomes.
Remove 'sandstone grassland' biome.
Rename 'stone grassland' biome to 'grassland' biome.
Edit biome points for improved similarity to Whittaker classification.
Change 'tundra' to bare stone with snowblocks.
Make dirt 'swamp' / 'shore' less deep.
Ores:
Make dirt blob ore biome-specific, limit to dirt biomes.
Decorations:
Make mushroom noise spread match that of appletrees as originally intended,
to have mushrooms spawn in darker thicker forest areas.
Add coral reefs in warm oceans.
Add bushes and acacia bushes.
Jungletrees in deeper water for larger swamps.
Register flower mod decorations in singlenode mapgen for use by
minetest.generate_registered_decorations, as in default/mapgen.lua.
Boats:
Previously, boats were not added to inventory in creative mode, fix.
In creative mode multiple boats will not be added to inventory.
Add comment.
Carts:
Set speed to 2 if punched by a non-player, to match the effect of a
player punch.
Add comments.
This is partly a workaround for a bug.
Climbs with continuous power rails were failing often due to
unexplained losses of speed leading to a reversal of direction.
The lack of acceleration on climbs meant that lost speed was not
regained.
Keeping cart speed at maximum on climbs helps reduce the chance of
reversals.
This also allows players to slowly accelerate up to full speed on a
climb without needing a horizontal run-up to reach full speed first.
It may not be possible to build the horizontal sections needed, or,
if players are replacing a previous carts mod their track
constructions, bridges, tunnels etc. will often not have the
horizontal sections needed.
Players will also sometimes need to place and enter a cart on a slope
and be able to climb.
- Improve arms attachment
The arm bones were at an angle, so that the bones were difficult
to orient correctly, as unintuitive combinations of angles
would be needed to get the default orientation, or any other
acceptable orientation. Moreover, a simple rotation of the arm,
e.g. forward, would require all angles to be adapted, instead
of just one.
The ends of the arms bones were moved from touching the body, to
the center of the arm, at an equal distance from the sides of the
arm and the shoulder; the arm bone is now in the center of the arm.
- Fix body rotation
The body was rotated 180° while the rest wasn't, leading to
strange results when setting bone positions manually.
- Fix default rotation of limbs (manually positioning them in
their default position would require an 180° rotation).
Is is not know how this was fixed. Maybe just because the
model was re-exported.
- The bone of the cape was moved to the center of the cape (it was
at the edge). For some reason this fixed the 180° rotation of the
cape when it was manually positioned (similar to previous issue).
The changes above fix most of the issues mentioned in #1376
- Add a player-model-specific workaround for the problem described in:
https://github.com/minetest/minetest/issues/2813#issuecomment-198796927https://github.com/minetest/minetest_game/pull/1392#issuecomment-261669915
During walking, attached tools would randomly switch hands. Walking also
happens to be the only animation where the body does not move. Making the
body move an imperceptible amount makes the issue disappear for the player
model.
- Fix body vertex group: it no longer includes parts of arms and legs
Thanks to @stujones11 for these last two changes.
This code adds the key concept to minetest_game, and integrates it
with lockable nodes. Currently supported lockable items are the Steel
Door, the Steel Trapdoor, and the Locked Chest.
The goal of this modification is to introduce a fine-grained multi-
player permission system that is intuitive and usable without any
console or chat commands, and doesn't require extra privileges to
be granted or setup. Keys can also physically be conveyed to other
players, adding to gameplay and adding some personality that is
preferable to console commands or editing formspecs.
A skeleton key can be crafted with 1 gold ingot. Skeleton keys can
then be matched to a lockable node by right-clicking the skeleton
key on a lockable node, which changes the skeleton key to a "key".
Gold was chosen as it's currently a not-so very useful item, and
therefore it's likely that players have some, but aren't really
using it for any purpose.
This key can subsequently used by any player to open or access that
lockable node, including retrieving items from Locked Chests, or
putting items in them.
They key is programmed to fit only the particular locked node it is
programmed to. This is achieved by storing a secret value in both
key and locked node. If this secret value doesn't match, the key
will not open the locked node. This allows many keys to be created
for one chest or door, but a key will only fit one node ever. The
secrets are stored in node, and item meta for the key.
If a locked node is removed, all keys that opened it are no longer
valid. Even if a new door/chest is placed in exactly the same spot,
the old keys will no longer fit that node.
Keys can be smelted back in gold ingots if they are no longer useful.
The method of storing a secret in nodemeta and itemstackmeta is secure
as there is no way for the client to create new items on the server
with a particular secret metadata value. Even if you could possible
create such an itemstack on the client, the server does not ever read
itemstackmeta from a client package.
The patch adds an API that allows other nodes and nodes added by
mods to use the same keys as well. The method how to implement this
is described in game_api.txt. The mod should add 2 callbacks to it's
node definition. Example code is given.
Textures are from PixelBOX, thanks to Gambit.
This merges the current state of the well-maintained and tested
`torches` mod as I've maintained it for the last 6 months.
This started out as a thorough cleanup of 3D torches by blockmen,
where some of the initial code still remains.
The models were redone entirely from scratch and have been extensively
tested with dozens of animated textures converted with mcimport,
and look a lot better than the original 3D Torches mod.
The ceiling torch is retained and functional. The `wieldlight`
addition that the torches mod has was removed, since it relies
on wieldview to look decent. This can stay external mod code.
I've opted to move the torch nodes to a separate file. It's not
a lot of code but nodes.lua is already huge, and I wanted to
retain the copyright header and some of the readme.txt notes,
and this was the easiest way of doing it.
This code passes "default:torch" to nodes with on_rightclick,
fixing problems with itemframes. Essentially it has a more
elaborate item_place() routine to make sure we're not passing
the wall torch to nodes that may display it.
The ceiling torch is a separate model and not the same as the
floor model. That does mean that there are 3 models in this
mod.
This is all the working code from SmallJoker's boost_cart, poored into
a more suitable form for minetest_game.
- Mesecons and moreores stuff was removed entirely.
- Textures were all renamed and moved out of default/
- Updated license, readme.txt, attribution
- Changed code license to MIT, left artwork at CC0
- removed default:rail and made aliases for it
- :carts:rail is now carts:rail.
- localized entity def
- removed copper rail entirely
- startstop rail was removed, as well as detector rail
- remodeled to b3d using stujones11 excellent blend model, but sizes
of cart adjusted to make pixel sizes consistent (0.625) everywhere.
- slightly more complex texture map for the cart (front/side visibly
different)
- rail parameters are passed as a separate def table, and stored in
a private list. This avoids having to call `get_meta` on every
node. In return, we need the node name, though.
- adds metal sounds (based on default metal sound function) and
cart moving sound.
- reduced cart speeds to max 7, 5 by pushing.
- Added on_step() rail event handler, gets called when a cart is on
a rail.
- Added various rebased updates from upstream (thanks Krock)
- Included a fix that removes the 'reverse jiggle' when stopping.
- Included reworked textures by sofar.
The mod namespace is still public, but I'm NOT declaring it an API. I'd
rather see it localized instead, for now. Any public interface in this
code is *experimental* at best, and should be considered non-stable and
unsupported for now.
Currently all minetest_game PR's are failing travis since the
upstream luacheck now also warns about whitespace issues, and
there are a few of those in the code. This fixes all of them
so we can yet again rely on luacheck.
With mip-mapping enabled, some GPUs cause a visual bug with indexed
textures that use alpha. This bug has been present for a while but
not noticed before. All indexed alpha textures must now be converted
to RGBA, to start this process we revert some textures converted to
indexed in the recent commit af3c918.
When placing boats, align the boat with the player's yaw.
Align drivers yaw with boat yaw when entering a boat, would previously turn
boat yaw by player's yaw + 90° to the right.
Make lava cooling ABM use a new group 'group:cools_lava'.
Nodes other than water can cool lava. We assume snowblock and ice melt,
turn to water and cool lava.
Leave 'group:water' present temporarily to not break mod liquids.
This fixes all cases where the color profile was broken, and
libpng warns about. It also makes almost all textures indexed
instead of RGB where possible (textures that don't have
semi-transparent pixels).
A deeper, darker level of leaves is created by tiling the texture
2 by 2, reducing brightness and offsetting this.
For a denser leaf appearence with the 'simple leaves' setting.
Also used for acacia bush leaves.
The purpose of this is to allow mods to be able to interact (e.g. fill up)
an empty bucket when it is used to punch a node that's not a liquid source
or when punching a custom entity (e.g. milking a cow).
- Use opaque texture for top+bottom of iron bar
- Add color variation for iron bar top/bottom
- Add paramat's texture to credits
- Update license info for paramat's textures
This plays when damage is disabled, an engine bug.
We can remove it because both sounds are identical, now it is removed
the 'player damage' sound still plays when falling damage is taken.
To allow mapgen bushes in green-grass and savanna grasslands.
Nodes for a generic bush and an acacia bush.
Stem nodes are craftable to a single wood node to provide a small
amount of wood resource in grasslands.
Fuel times are that of corresponding 'wood' nodes, 1/4 that of
corresponding tree nodes.
No leafdecay to enable use as hedges or without a nearby tree trunk.
Uses 'default leaves simple' texture for extra visual thickness.
Use 'player damage' sound for both damage and falling damage.
Gains for damage sounds are set in the engine, however we cannot change
those gains as other subgames already use damage sounds based on those
gains.
Sound has been re-edited from source and normalised to 0 dB for
maximum volume, which is only just enough because gain is fixed at 0.5
in the engine.
The check for igniters (fire/lava) will be performed every 10 secs
if the item is flammable.
if the item is found to be in lava it will then burn up and
disappear in a smoke puff.
If a non-lava igniter node is found, a combination of `flammable`
value of the item and `igniter` group value of the node will be used
to determine the chance for the item to be removed.
'jungleleaves simple' had completely different leaf colours to
'jungleleaves', now matched.
'leaves simple' had dark green instead of black colour for transparent
pixels (the 'leaves' texture uses black), normally these pixels would
not be rendered as opaque colours but bush nodes now use this texture
and will be rendering it as opaque. The dark green pixels resulted in
a texture lacking in contrast.
River water needs to be 'liquid_renewable = false' to avoid a mess caused by
spreading of sources, however picking it up with a bucket then creates
a hole in the river. Allow a 'force-renew' of the source node if it has a
source neighbour.
Pass nodename to tnt.burn function where possible to reduce
use of 'get_node'.
Change 'ipairs' to 'pairs'.
Use 'nodeupdate_single(pos)' instead of 'nodeupdate(pos)' to
avoid every node triggering recursion, the loop itself takes
the place of recursion and works upwards through horizontal
planes as required.
Credit to tenplus1 for the suggestion to generalise for mod use.
Mods can add mod nodes to 'group:spreading_dirt_type' enabling the
function to work with mod nodes.
Add some nodes to this group.
Removing 'dirt_with_grass' etc. from 'neighbors' stops the ABM action
running everywhere and constantly, on the dirt nodes immediately below
the surface nodes. Now the action only runs in the rare case of a dirt
node with neighbouring air, grass decorations or snow.
Remove check for air above to allow grass to spread under light-
transmitting nodes such as fences, walls, plants. This causes spread
under slabs, stairs and glass, when near air, but seems worth it.
Remove unnecessary check for nil node.
The collision box still extended into a neighbouring empty node, causing
falling node objects to collide but not transform back into normal nodes.
Completes the fix started in a previous similar commit.
Combine slabs if identical based on orientations using a simple lookup
table if the nodes are identical.
Otherwise relies on place_node() to place the node, which properly
handles rotation compared to adjacent nodes already, and can orient
based on look_dir as well.
Initial slabs placed are oriented based on (1) the orientation of
the pointed "face" (assumes nodes are cubic, of course), and uses
the player look direction to orient the node n/e/w/s if the slab
is horizontal or upside-down. If placed against a vertical face,
the slab is placed against the face without rotation around the axis
perpendicular to that vertical face. This allows upside down placement
and vertical placement without screwdriver.
If a slab is placed on top of an upside down slab, or below a normally
placed slab, the rotation is inverted so that no "floating" slab
is created.
Largely based on kilbith's #807 PR. Slab combining and place_node()
usage by sofar.
Since this relies entirely on `on_place` mechanics, this fails to
combine slabs into a plain node if the space *above* is occupied.
This is unavoidable due to the fact that on_place() happens after
the checks required to see if pointed_thing.above is empty or not.
I've rewritten this to use connected nodeboxes, but with a caveat. In
order to make flat nodes look better, I'm keeping one non-connected
pane that is flat around to convert flat sections to the flat nodes
instead of connected, as these look better and are easier to work
with. Once more sides are needed we convert the panes on the fly to
connected nodes and recalculate the shape.
We don't paint any of the half-panes that the previous generation of
xpanes did. There's no need and it's harder to work with. Updating the
nodes also seems more natural and placement and removal works straight
forward.
The conversion of old panes relies on an LBM, and does a reasonable
conversion job, but it's not exact, since the panes behave slightly
different now.
The game API documentation was wrong to begin with. We discard param
nr. 2 of the API entirely, and correct the tile usage text.
Part 1: All mods except default and xpanes.

Burn time is unchanged for applewood, and increases in the order:
aspen, pine, apple, acacia, jungle which is also the order of wood
colour darkness.
Indicate in the infotext when a furnace has filled up `dst` but still
has fuel. The info text shows the item as 100% with added "(output
full)" text, indicating that while it can cook the item, there is no
place for it in the `dst`. Emptying the `dst` should make the item
cook immediately and furnace resume normal operation.
Dig time is modified according to difference (leveldiff) between tool
'maxlevel' and node 'level'. Digtime is divided by the larger of leveldiff
and 1. In creative mode, where the hand is redefined to have maxlevel 3,
this results in higher level nodes taking significantly longer to break.
Now, to speed up digging, hand 'maxlevel' and 'digtime' have been
increased such that nodes of differing levels have an insignificant
effect on digtime. Dig time for all nodes is now identical to that of, for
example, dirt nodes.
Make the softer woods, pine and aspen, 'flammable = 3'.
Correct inconsistent flammability of wood and stairs in relation
to all other solid wood nodes in MTGame.

Other screwdriver mods, or mods that cause rotation, might operate without the screwdriver mod loaded and have `screwdriver.disallow` unavailable.
This allows nodes to default to full-disallow rather than full-rotation in such a situation.
This fixes the TNT bug that can crash game when blowing up a container
which holds huge stacks above the norm... e.g. give yourself 65535 snow,
place in chest, blow up, stalled!
Previously, the collision box extended into an empty node, causing
falling node objects to land on the open gate but not transform

either side of the end of the open gate and transform back.

Nyancats are independent in the default mod. Nothing else uses them or

Allow many crafted nodes to be rotated in any way possible.
These blocks all have slab and stair versions, which can create awkward
patterns if placed together. By allowing these to be rotated players
can create new patterns and appearances that were not before possible.
Since this wasn't possible before, there won't be any effect
to existing builds, as param2 should always be '0'. The current
screwdriver mod also refuses to rotate and alter param2, so this is
safe to enable from now on.
Personally, since these are all *crafted* nodes to begin with, it
should be apparent that they can be rotated to begin with, but I can
see people may disagree from a simplicity perspective. It also may
affect param2 usage that other mods rely on, although I'm not aware
of any mods that do this.
Lowering the top surface to be level with the boat top somehow

Allow water to turn cobble slab and stairs to turn into mossy versions.
There is no crafting recipe for mossy stairs and mossy slabs, the

The slabs and stairs will turn mossy when water is adjacent, just like
cobblestone. You can either farm mossy versions by placing them in
water for a while, then collecting them, or run water over your craft.

Because the fire nodes are not removed 100% when there are
no more burnable nodes nearby, they can potentially stay around
for very, very long times, leading to ABM trains every 5 seconds
for no good reason (only 1 in 16 will be removed every interval).
A much better method to remove fire nodes is to remove them by
timer, and give removal a 100% chance if no flammable nodes are
adjacent. This makes fire cleanup a lot faster and more natural,
and will reduce the amount of ABM hits making fire overall more
responsive.
We also remove the 1 in 4 chance and fold the removal of flammable
nodes into the ABM chance.
There's some low hanging fruit cleanups in here as well.
Each sapling is given a single node timer that is between
2 and 4 days of game play time (40-80 minutes). If you walk out
of the zone, and come back later, the tree will always grow
to full if the timer has elapsed.
Because trees.lua is all functions, it needs to be parsed before
nodes.lua, since that references some of its functions. Hence,
change the order of parsing here. Otherwise saplings would not
grow to full.
This PR requires @minetest/minetest#3677
Farming and plant growth has traditionally in minetest been
implemented using ABM's. These ABM's periodically tick and cause
plants to grow. The way these ABM's work has several side effects
that can be considered harmful.
Not to mention a comprehensive list of downsides here, but ABM's
are chance-dependent. That results in the chance that some nodes
potentially never get processed by the ABM action, and others get
processed always. One can easily find this effect by planting a large
field of crops, and seeing that some nodes are fully grown really
fast, and some just won't make it to fully grown status even after
hours or play time.
One could solve the problem by making the ABM's slower, and giving them
a 100% of action, but this would cause the entire field to grow a step
instantly at ABM intervals, and is both ugly, and a large number of
node updates that needs to be sent out to each client. Very un-ideal.
With NodeTimers though, each node will see a separate node timer event,
and they will likely not coalesce. This means that we can stop relying
on chance to distribute plant growth, and assign a single timer event
to grow the plant to the next phase. Due to the timer implementation,
we won't ever miss a growth event, and we can re-scehdule them until
the plant has reached full size.
Previously, plants would attempt to grow every 9 seconds, with a
chance of 1/20. This means typically, a plant would need 9*20 seconds
to grow 1 phase, and since there are 8 steps, a typical plant growth
would require 9*20*8 ABM node events. (spread out over 9*8 ABM actual
underlying events per block, roughly).
because plants are likely not growing to full for a very long time
due to statistics working against it (5% of the crops take 20x longer
than the median to grow to full, we'd be seeing ABMs fire possibly
up to 9*20*8*20 with a 95% confidence interval (the actual math
is likely off, but the scale should be correct). That's incredibly
wasteful. We'd reach those conditions easily with 20 plant nodes.
Now, after we convert to NodeTimers, each plant node will see exactly
8 NodeTimer events, and no more. This scales lineairly per plant.
I've tuned the growth rate of crops to be mature in just under 3
whole days. That's about 1hr of game time. Previously, about half
the crops would grow to full in under 2 days, but many plants would
still not be mature by the end of day 3. This is more consistent.
An additional problem in the farming mod was that the final fully-grown
plant was also included in the ABM, causing infinite more ABM's even
after the entire field had grown to completion.
Now, we're left with the problem that none of the pre-existing plants
have actual node timers started on them, and we do not want a new ABM
to fix this issue, since that would be wasteful. Fortunately, there
is now an LBM concept, and we can use it to assure that NodeTimers
on crop nodes are properly started, and only have to do the actual
conversion once per block, ever.
We want to provide a fairly similar growth rate after this conversion
and as such I've resorted to modelling some statistical data. For this
I created a virtual 32x32 crop field with 9 steps (8 transitions)
as is the default wheat crop. We then apply a step where 1 in 20
plants in the field grows a step (randomly chosen) and count the
number of steps needed to get to 25%, 50, 75% and 95% grown.
The resulting data looks as follows:
25% - ~120 steps * 9 sec / abm = 1080s
50% - ~152 steps = 1368s
75% - ~194 steps = 1746s
95% - ~255 steps = 2295s
Next, we want to create a model where the chance that a crop grows
is 100% every node timer. Since there will only be 8 steps ever,
we want the slowest crops to grow in intervals of ~ 2300 / 8 seconds
and the fastest 1/4 of crops to grow 1080 / 8 seconds intervals.
We can roughly compare this to a normal distribution with a median
of 1400 with a stddev of ~350 (thick fingering this one here).
The rest is a bit of thick-fingering to get similar growth rates,
taking into account that ABM's fire regularly so if they're missed
it's fairly painless, but our timers are going to be 1-2 minutes
apart at minimum. I calculate the timer should be around 150s
median, and experimented with several jitter ranges.
Eventually I settled for now on [80,200] with a redo of [40,80],
meaning that each growth step at minimum takes (80 to 200) seconds,
and if a negative growth condition was found (darkness, soil not
wet, etc), then the growth step is retried every (40 to 80) seconds.
The end result is a growth period from seed to full in ~ 2.25
minetest days. This is a little bit shorter than the current
growth rate but the chances you'll miss timer ticks is a bit
larger, so in normal gameplay it should be fairly comparable.
A side effect is that fields grow to full yield fairly quickly
after crops make it to mature growth, and no crops are mature
a very long time before the majority grows to full. The spread
and view over a growing field is also fairly even, there's no
large updates with plenty of nodes. Just a node here or there
every second or so in large fields.
Ultimately, we get rid of ABM rollercoasters that cause tens of
node updates every 9 seconds. This will help multiplayer servers
likely a lot.
Standing on a boat makes you appear to "hover" over it since this

This uses a vmanip to count adjacent tnt nodes and explodes them
all at once, using an inverse square law to recalculate the radius.
The maximum explosion becomes 125 nodes of tnt yielding a radius of
15 nodes, which does not break my machine and makes it return
in under a second.
This makes both bigger explosions and less stability issues.
The drop code has been simplified and now drops at all times a
reasonable amount of drops, never blanketing the area with drops,
even at the larges explosion level.
Particles are scaled up according to explosion size as well - a
bigger explosion will show bigger particles.
To scale the tnt:boom particle, we move it to the _effects() function.
Introduces an `on_blast(luaobj, damage)` callback that mods can attach
to an entity def. The function will get called with the damage that
TNT would make.
The function should return three values:
bool do_damage, bool do_knockback, table drops
do_damage allows the mod to tell the TNT code to perform damage on
the entity for the mod. The mod code should not do anything with
the entity HP. The entity should not be immortal. If false, then
the entity will not be damaged by the TNT mod.
do_knockback allows the mod to tell the TNT mod to perform an
entity knockback effect. If false, no knockback effect is applied
to the entity.
the drops table is a list of items to drop. It may be nil. E.g. {
"wool:red" }.
I've documented both on_blast() API methods in game_api.txt. It is
a better place than lua_api.txt.
Any second explosion near a first TNT explosion will punch all
entities found nearby, including item drops. This causes the
item pickup code to think the item was picked up, but by
a `nil` player, thus removing the item.
We query for the immortal entity group, and if the item is in
the immortal group, do not punch the item.
We reuse the tnt:boom texture for a particle that is added by the
on_construct() of tnt:boom, and has a short expiry time (0.2sec).
It is 3 nodes larged, centered on the explosion.
We then make tnt:boom airlike so it doesn't have a texture, and it's
the thing that emits lots of light (we could even make it exist a
bit longer).
The nice thing about particles is that the client is less susceptible
to lag and will always remove them as fast as possible, so this makes
the visual more constant and responsive.
The effect is similar, and the reduction in particles is a small
boost in responsiveness.
To compensate, I've lowered the spawner time and expiration length
as well.
We add a +/- 0.5 random value to the velocity vector of
ejecting nodes.
I've spotted a lot of nodes going exactly straight up if blowing
up sand above TNT. The extra variation looks less artificial.
We apply punch damage to mobs caught in the blast radius, as
this code previously only hurt players.
We "move" players back 1 node if they're caught in the blast, and
slightly up. We can't "eject" players due to missing API code to
support that, unfortunately.
Adds a minor helper function that allows efficient retrieval of
several inventories from a node inventory. We use this helper to
quickly retrieve the items in chests, vessel shelves, book shelves
and furnaces, and return these with the nodes itself to the TNT caller.
The TNT caller then performs the entity physics, and we don't need
to do anything else.
We disable TNT doing anything with bones.
We expose a bug in the code that drops the items - metadata was lost
entirely. This patch corrects that by properly copying the metadata
and creating the drops list inclusive metadata.
This changes how dirt blocks turn to dirt_with -grass, -dry_grass
or -snow.
Previously, dirt that was sunlit would turn to dirt_with_grass no
matter what, but this happened without any context, so you could
get green patches of dirt_with_grass in the middle of a savannah or
even desert.
Dirt no longer turns to covered dirt unless it's within 1 node from
another dirt_with_grass or dirt_with_dry_grass or dirt_with_snow.
This makes dirt_with_grass "growback" a lot slower, since it now only
happens on the edges, but it retains the context nicely now.
If there is any dirt with a grass or dry grass plant, or snow on top,
and enough light, we'll convert it sporadically to dirt_with_grass
or dirt_with_dry_grass or dirt_with_snow.
This allows us to plant grass of our choice in a large dirt patch,
or in a region where otherwise that type of grass is not present.
This used to be done by 2 abms, but I've combined them in to a single
ABM that is ordered to run with maximum efficiency, solving for the
most common outcome first before attempting more complex checks.
This is technically "dirt with grass" that's just under a snow
cover, so in darkness the grass on these nodes will also die,
turning it into dirt.
This doesn't convert dirt_with_snow under snow.
We add on_create() handlers for both burning TNT and burning
gunpowder. Because gunpowder will explode TNT in 1 second,
and not 4, we need to modify the 4 second timer after we
make the TNT burning. Other mods can now place burning TNT
that will by default explode after 4 seconds.
I spotted two places where under stress (many explosions) luajit would
end up passing nil to these functions. I'm not entirely sure how,
but it seems good form to guard against it, which does make it
more robust. After this patch, I'm not able to crash the server. With
many explosions, it may still lag significantly, but always returns
in the end.
We define the blast intensity as the square of the tnt_radius, divided
by the square of the distance to the explosion center, where distance
is limited to 1 at the lower end.
When destroying nodes, we calculate the intensity for each node, and
only destroy the nodes when the intensity is 1.0 or larger. To avoid
perfectly spherical explosions, we make sure to retain a randomness
factor of 20%. This will make explosion edges jagged and not smooth,
but not too much.
We pass the calculated intensity to on_blast() functions as well,
except we take the jitter here out and make sure it's always 1.0
or larger.
We apply a log scale to the size of the stacks ejected, so that
in larger explosions we are getting larger stacks. For normal r=3
explosions, this gives stack sizes ~6-7 or so, but for r=10 explosions
it could end up giving stacks of 25+.V
The drops list already has quantities, so let's just select the one
with the highest quantity from it, and use that as tile. Fallback
tile will therefore only be used if explosion happens in air. Oh well.
We add a dirt-like particle (drawn from scratch, uses some
colors from default_dirt's palette) to spawn many particles
that have collision enabled around the center of the blast.
This has the effect of obscuring the center of the blast, as
that is a painfully visible empty area when the explosion happens,
as there's only a little spark.
The dirt particles bounce around the walls and floor a bit,
and disappear rapidly, well before the smoke particles disappear.
This is a nice visual distraction that obscures the sudden
appearance of the gaping hole, and makes it a whole lot more
believable.
But not too much.
TNT is a bit underwhelming at the moment. We can make it a bit
more interesting by ejecting not just one or two itemstacks,
but a bunch of them. This code splits up the drops into
separate itemstacks that are 2-5 items together, which
results in generally roughly 10 itemstacks being ejected.
Since now we have multiple ejecta, it makes sense to tune
the ejecta velocities a bit better to get the appearance of
an actual explosion better. The items will not all start
with the same vertical velocity, since that would look
like fireworks. Instead we give them all a different vertical
speed.
If the node is special and has an on_blast() handler, we need
to call it instead of getting node drops manually. However, we
do want to know if drops should be added for the special nodes,
so we modify the on_blast() handler code to allow the nodedef
handlers to pass back itemstacks. This could be used by e.g.
the doors mod to drop door items after a blast.
Since this API is documented in lua_api.txt, a separate PR will
be incoming to update the on_blast() documentation.
Some people borrowed the creative code for their sub-games with an exclusive attribution to celeron55.
This is frustrating since I've largely rewritten, redesigned and carefully maintained this mod for the last months.
I expect to be credited.
Currently any doors viewed from underwater will disappear but removing the line 'use_texture_alpha = true,' seems to fix this. Thanks to Thomas-S for finding this glitch.
The boat model had over 1700 tris (!) before this redo. I've reduced
the amount of tris to ~150, which is very reasonable given that there
are almost 45 faces to this model.
I've also spent a good hour re-UV unwrapping the entire model which
has a huuuge impact on the boats' appearance. As much as possible,
the boat now looks like it's made out of actual blocks of wood,
and I've even attempted to make the grains connect around edges,
appear in the same pattern and spacing, and generally make it look
like it's just a nice crafted thing out of several pieces of wood.
I've had to tweak the rudder part to make the texture actually have
square texture pixels. I did that by varying the vertical position of
the botton of the rudder handle and the top of the rudder bottom, which
worked well. I also had to 'slice' the rear face of the boat to prevent
a strange texture tear, probably due to non-flat surface somewhere,
but I couldn't spot the issue there anymore after adding 2 extra edges.
This looks totally like a new boat now.

If LVM or some other nonmetadata method is used to place a door,
then metadata is missing that tells us whether the door is left
or right-hinged.
However, we can detect that nodemeta is missing and see if the node
name is _a or _b. In the case of _a, nothing needs to be done and we
can just open the door. In the case of _b we assume the door is right
hinged, and tune the state nodemeta value so that the door opens the
right way. This all of course assumes that the schematic method places
the doors *closed* by default, which is reasonable.
- disallow placing beds in protected areas
- fix rotation of beds(broken after 41c2b2ae)
- allow using others' beds, but don't change spawn location
Fixes#953. #943 isn't something I think was ever implemented, and
this does a fair job of addressing the main concern (spawning in
others' houses)
We were cleverly attempting to use an airlike node as the
top half of the doors, but as airlike nodes are not walkable,
falling nodes would not stop falling and thus remain an entity
stuck on top of a door.
After inspecting the builtin/game/falling.lua code, I considered
the remaining options: (a) revert doors such that the top part is
actually the door, (b) play with nodedef fields and see if other
flags may work, or (c) modify the hidden door part to another
drawtype that properly prevents this issue.
(a) seemed way over the top for now, although it would solve the
issue, it would cause a rewrite of most of the code including the
old-door-conversion.
(b) turned up nothing.
(c) turned out to be relatively simple.
So, here's the implementation where I turn the hidden door top
into a tiny, non-targetable but walkable nodebox that is entirely
inside the door hinge. It's entirely transparent, so you still
can't see it, can't hit it, nor can you place anything in it or
make liquids flow through it. The top part is placed in the right
position on placement and not touched further.
Falling nodes will properly stop on top of these doors. I've
adjusted the door conversion code to properly account for the
issue as well, so the only thing remaining is people who have
been running a git branch - those can upgrade by re-placing the
door.
the ```group:cracky``` group contains all sorts of odds and ends
nodes that we shouldn't connect to. There are a few nodes that
walls now no longer connect to, that probably should get
```group:stone``` added, or something similar, though.
