User:Köpleres/Caves & Cliffs (Java)

1.17, the first release of Caves & Cliffs: Part I, is a major update to announced at Minecraft Live 2020 and released on June 8, 2021.

On April 14, 2021, Mojang Studios announced that the update would be split into two updates due to the amount and complexity of content, as well as team health. Multiple features such as revamped mountain and cave generation, the lush caves and dripstone caves biomes, and increased world height were removed in 21w15a, and were subequently released in 1.18. A data pack was included in the Minecraft.net article for 21w15a that re-enabled the removed features, and subsequent snapshots updated this data pack.

 * The tilt happens in 3 stages: unstable, partial, and full. These can be seen in the F3 debug menu.
 * All the stages are solid except the full stage, which is when the player falls through.
 * When nobody is standing on it, it is set to none stage.
 * The tilt can also be triggered by hitting the plant with a projectile.
 * The tilt can be prevented by powering it with redstone, but hitting it with a projectile still causes it to tilt.
 * Comes in two sizes: small and big. Small can be applied bone meal to grow into big.
 * Small dripleaf can be obtained only with shears (otherwise breaks) and can be planted on clay or moss blocks, or underwater on clay and dirt blocks.
 * Big dripleaf can be obtained with any tool or by hand and can be planted on grass, dirt, and moss blocks.
 * Both sizes can be found inside lush caves, which can currently only be accessed through the single biome, caves, or floating islands world types.
 * It is available in Survival through the wandering trader.


 * Dripstone Block
 * A decoration block.
 * Appears to be made of the same materials as stalactites and stalagmites but as a full cube.
 * Generates mainly in the dripstone caves biome, which is currently available only through single biome, caves, or floating islands world types.
 * Dripstone clusters can also be found rarely in regular caves.
 * Can be crafted from 4 pointed dripstone.

 * Obtained with shears, otherwise breaks.
 * It can also be obtained using a hoe on rooted dirt turning it into normal dirt.


 * Infested Deepslate
 * An infested variant of deepslate.
 * Spawns a silverfish when mined.


 * Light
 * A new waterloggable source of light, originally from.
 * Only available with commands such as.
 * Behaves like air and it is visible only when the item is held, similar to barriers.
 * Unlike barriers, light blocks can only be targeted when holding the item.
 * The light level it is emitting can be changed by interacting with it.


 * Lightning Rod
 * Can be crafted with 3 copper ingots.
 * Lightning strikes within a 32-block radius get redirected to the lightning rod.
 * Turns completely white when struck by lightning.
 * Gives off a redstone signal with a strength of 15 if hit by lightning.
 * Can be activated directly by throwing a trident with Channeling at it during a thunderstorm, though this does not produce a redstone signal.


 * Moss Block
 * An opaque block with a grass-like texture on all sides.
 * Can be fertilized with bone meal to grow grass, tall grass, moss carpets, and both types of azaleas on it and in its vicinity.
 * Can be fertilized with bone meal to grow over (expand) across stone surfaces, but not grass surfaces.
 * Breaks when pushed by a piston or sticky piston.
 * Can be combined with cobblestone or stone bricks to make the mossy versions of those blocks.
 * Vines can still be used, in addition to moss blocks.
 * Hoes are the appropriate tool to collect it.
 * Small dripleaf can be planted on it.


 * Moss Carpet
 * Same texture as the moss block, but one pixel thick.
 * Can be crafted with moss blocks, or be obtained by applying bone meal to them.


 * Pointed Dripstone
 * Can be either placed on a ceiling to create a stalactite or on top of a block to create a stalagmite.
 * Can be combined to form longer stalactites and stalagmites.
 * Thrown tridents break pointed dripstone. They also break when pushed directly or with a block by a piston.
 * Stalagmites break if not attached to something below.
 * Stalagmites hurt entities that fall on top of them more than normal fall damage.
 * Damage is relative to height: For example, jumping on a stalagmite deals of damage, and falling from 3 blocks deals  of damage.
 * Stalactites can fall or break if unsupported, and break apart on impact, hurting entities they fall on.
 * Damage is relative to height: For example, one falling from 2 blocks deals of damage, and one falling from 3 blocks deal  of damage.
 * They drip water or lava into cauldrons if a source block is placed above the stalactite, and gradually fill the cauldron. Water drips even without any water above the block (as does lava in the Nether) but this effect alone does not fill the cauldron.
 * If a stalactite is hanging from a dripstone block with a water source above, it will slowly grow both the stalactite from above and a stalagmite from below.
 * Growth speed is random but very slow; a single growth step can take several in-game days.


 * Potted Azalea
 * Obtained by planting an Azalea Bush into a pot.


 * Powder Snow
 * A variant of snow, entities that walk over it sink into it.
 * Leather boots can be worn to prevent entities from sinking into powder snow blocks.
 * Players can still crouch to descend with leather boots. Wearing leather boots also allows powder snow to be "climbed", like water or scaffolding. They also prevent fall damage when landing on powder snow.
 * Leather Horse Armor also protects horses from freeze damage.
 * When inside a powder snow block, a frosty vignette appears around the player's screen and any entity (with the exception of strays, polar bears, snow golems and withers) inside starts freezing and taking damage after a short time.
 * Wearing any piece of leather armor stops the freeze effect.
 * Can be collected and placed with a bucket.
 * Entities on fire melt powder snow when colliding.


 * Rooted Dirt
 * A dirt-like decorative block with roots on its texture.
 * Similar to coarse dirt, neither mycelium nor grass spread to it.
 * bone meal on any side grows hanging roots underneath.
 * Tilling rooted dirt with a hoe will now convert it into dirt, and pop out hanging roots.


 * Sculk Sensor
 * A redstone component that detects vibrations.
 * Currently, it does not generate naturally, available only from commands such as, but natural generation is planned for future versions.
 * Senses vibrations such as block placement, footsteps, and projectiles, and emits a redstone signal.
 * Vibration JE1 BE1.gif Emits particles when it senses a vibration nearby.

 * Can hold only one stack of items, but is able to hold different types of items inside of it.
 * Items with smaller stacks, such as ender pearls, take up more room in a bundle, and non-stackable items take up the whole bundle.
 * The bundle's contents can be opened by pressing while holding it, throwing out its entire content into the world. When destroyed as an entity, it drops the items it currently has as well.
 * Right-clicking a bundle in the inventory empties one item from the bundle.
 * The player receives a tutorial when first having a bundle in the inventory.
 * Even though bundles are not stackable, bundles can be nested.
 * Can hold up to 16 bundles.

 * Certain types of ores and structures still generate in the deepslate layer, as well as tuff and gravel.
 * Dirt, diorite, granite and andesite do not generate in this layer.
 * Biomes such as the dripstone caves and lush caves now generate in the underground.
 * Contain aquifers, bodies of water with different heights, independent of sea level (Y=63).
 * Aquifers below Y=0 sometimes generate with lava instead of water.
 * Improved old caves to blend in with the new generations of caves better
 * New noise caves, coming in 3 forms, "cheese", "spaghetti", and "noodle".
 * Cheese caves have large stone towers stretching from the bottom of the cave to the top, and are often large enough to allow safe elytra flight.
 * Spaghetti caves are long, thin caves that have small aquifers and are more similar to original caves.
 * Noodle caves are thinner, squigglier, and more claustrophobic variants of spaghetti caves.


 * Mountains
 * Come in 6 sub-biomes:
 * Meadow
 * A grassy elevated biome that looks like a flowery and colder plains, with an aqua grass color and dark blue water color.
 * Generates in plateaus and the lowest layers of some mountains, usually near plains and other temperate biomes.

 * Only goats spawn in this biome.
 * Pillager outposts can generate in this biome.
 * Stony Peaks
 * One of three biomes that generate in the mountain peaks.
 * Covered in stone, gravel, and strips of calcite.
 * Tends to generate in any peak surrounded by warm biomes such as jungles and savannas, to avoid temperature clashes.
 * No animals spawn in this biome.
 * Pillager outposts can generate in this biome.

 * Long and rare ore formations.
 * Copper ore veins mixed with granite and blocks of raw copper generate above Y=0.
 * Iron ore veins mixed with tuff and blocks of raw iron generate below Y=0.


 * Amethyst Geodes
 * A new feature found uncommonly underground (can rarely appear exposed to the surface close to sea level).
 * Contains blocks of amethyst and budding amethyst blocks, which are encased in a shell of calcite and smooth basalt.
 * Also generates with a small air pocket nearby that may open into the geode.
 * Generates up to Y=30.
 * Overrides standard caves and ravines, but is overridden by abandoned mineshafts.
 * Currently has a high generation rate, presumably for testing purposes as with ruined portals in the 1.16 snapshots.


 * Azalea Tree
 * Generate above lush caves, either on the surface or underground.
 * Consist of azalea leaves (both variants), oak logs and rooted dirt.


 * Upgrading of old worlds
 * The biomes and terrain from old and new chunks now seamlessly blend, preventing the hard cut borders from before. Any player-made structures in these chunks may either be intact, buried, or deteriorated.
 * Several checks are made on the previous bedrock layer to determine whether or not a chunk should generate new terrain below.
 * The game first checks if there is any bedrock at Y=0.
 * If bedrock is detected, the game then checks if each column in a chunk has air at Y=0. New terrain generates only under columns with non-air blocks.
 * If there is no bedrock whatsoever at Y=0, the whole chunk does not get new terrain below.
 * The old bedrock layer between Y=0 and Y=4 in old chunks gets replaced with deepslate.
 * A new bedrock layer is placed between Y=-64 and Y=-60.

 * Ore distribution
 * Changed ore generation of all ores making them have a spread value like lapis lazuli ore. Some still retain a linear generation alongside a spread generation.
 * Coal ore attempts to generate twice: once, evenly between an altitude of Y=136 and Y=256; and as a spread, peaking at an altitude of Y=96 and generating between an altitude of Y=0 and Y=192.
 * Copper ore generates between Y=-16 and Y=112, generating the most at Y=48 and like all other ores, uses spread. It peaks at Y=48. Bigger blobs of copper ore generate in dripstone caves.
 * Iron ore attempts to generate three times: once as a spread peaking at an altitude of Y=256, generating above Y=80; another as a spread peaking at Y=16 and generating with a minimum height of Y=-24 and a maximum height of Y=57, and a smaller one spreading evenly between the altitudes of Y=-64 and Y=-32.
 * Gold ore generates between the altitudes of Y=-64 and Y=32, peaking at Y=-16. Also, extra gold generates below Y=-48. The extra gold that generates in the badlands biome was increased, with a top height limit from Y=79 to Y=256, and increased number of blobs.
 * Lapis lazuli ore attempts to generate twice: once, as a spread between the altitudes of Y=32 and Y=-32, peaking at an altitude of 0; and evenly between the altitudes of Y=64 and Y=-64, generating buried like ancient debris.
 * Redstone ore attempts to generate twice: once, evenly between an altitude of Y=15 and Y=-64; and as a spread, peaking at an altitude of -64 and generating below an altitude of Y=-32.
 * Diamond ore now generate as a spread, generating below Y=16 and peaking at depths near Y=-64.
 * Emerald ore generates above Y=-16 as a spread, peaking at Y=256 and decreasing in quantity as the altitude decreases.
 * The size and positioning of diorite, andesite, granite, gravel and dirt has been tweaked - there are larger blobs of these blocks but they're fewer and further apart.
 * Diorite, andesite and granite generate less commonly above Y = 60.


 * Pillager outposts
 * Now generate in all the new mountain biomes.


 * Springs
 * Lava springs can now generate amid calcite, dirt, snow block, powder snow and packed ice.
 * These changes allow lava springs to generate in mountains and snowy terrain.

 * General
 * The overworld now uses the multi-noise biome source type.
 * Terrain generation is now independent from biomes, with biomes adapting to whatever terrain they happen to generate throughout.
 * This allows for natural variation in the terrain of any individual biome, both in terms of shape and elevation.
 * For example, forests and deserts could form up on a hill without needing a special biome just for that purpose.
 * This additionally allows for smoother transitions between biomes.
 * Terrain is now smoother and more extreme.
 * Bedrock layers generate dependent on the world seed now.
 * New random number generator is used for overworld generation.

 * When the inventory effects list is visible, it is hidden from the game view to reduce screen clutter.
 * There are now two effect-list vews, compact and classic:
 * Classic is the pre-existing list of effects, one after another.
 * Compact is a single icon for each effect, suitable for small screens.
 * The game automatically switches between the two looks to suit the available screen space.

 * Reworked world spawn selection algorithm.
 * Now spawns according to the same climate parameters that control biome placement and world generation: players should no longer be able to spawn in the ocean or some other inconvenient location.


 * Resource packs


 * Size limit for server resource packs has been increased from 100 MB to 250 MB.


 * Scoreboards
 * Removed length limits for scoreboards, score holders and team names.


 * Server

 * To run different main class than server, use property.
 * If this property is set to an empty value, the server just validates and extracts files, then exits.
 * Server classes are now signed.


 * Splashes
 * The splash "[this splash text has been delayed until part 2]" has been changed to "[this splash text is now available]".
