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.
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.
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
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.
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.
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.
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.
- 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.
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.
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.
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.
Retain definitions for node groups to support mods.
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.
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.
Make the the softer woods, pine and aspen, 'choppy = 3'.
With thanks to contributor tenplus1
Remove leaf cache and globalstep accumulator limiter
Use 'pos' instead of 'p0'
Remove non-essential 'group:liquid' from 'neighbors'
Increase chance value to 10 to compensate for disabled cache
Disable 'catch-up' to avoid the ABM often becoming 10 times more
intensive
Remove use of 'do preserve' bool, instead simply 'return'
Remove unnecessary checks for 'd' and 'd == 0'
Don't 'get' n0, use already present 'node' instead
Swap order two conditionals so that the one most likely is first
Allows walking in, and prevents being trapped in, 2 node high spaces.
Simulates player's feet sinking into snow.
Easier jumping up onto nodes with snow.
Add a global 'intersects protection' function to functions.lua for
checking if a specified volume intersects with a protected volume.
A 3D lattice of points are checked with an adjustable interval.
Add a global 'sapling on place' function to avoid duplicated code in
nodes.lua.
Nyancats are independent in the default mod. Nothing else uses them or
their code. Separating it into a separate mod makes it easier for
subgames to remove them. It also makes it easier for a mod to depend
on nyancats, as lots of subgames don't have them.
Default/mapgen.lua: Register biomes, ores and decorations in
singlenode mapgen. These were never disabled anyway because
singlenode was removed from the world creation menu.
* Unused variables
* Unused values (assigned to variables, but overwritten before use)
* Defining already defined variables instead of reassigning to them.
Preserve overlapping registrations of large and small clusters
below y = -64 but now extend the small clusters up to y = 0 (the
previous highest iron ore level) in a similar to way to coal
Re-order registrations
Add and improve comments
Change sand blob ymax to 0 as sand does not always rise above 0
Remove dirt blobs from sandstone as it is unsuitable for
many sandstone biomes and ugly in stony sandstone desert
Change ymax of first iron region to 0
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.
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
stair/slab API has been modified to allow for a recipeitem that
is `nil`, which will omit adding a crafting recipe for these two
items. The API documentation is updated.
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.
Mese texture is a classic-mese-yellow version
of celeron55's texture used in MTv0.4.0
Add missing texture credits for mese crystal
and mese crystal fragment
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.
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.
