{{exclusive|java}} The '''Caves & Cliffs Prototype Data Pack''' is an official [[data pack]] that was released periodically by Mojang Studios from April 2021 to May 2021.[https://feedback.minecraft.net/hc/en-us/articles/4402614709389-Caves-Cliffs-Prototype-Data-Pack-for-Minecraft-Java-Edition Caves & Cliffs Prototype Data Pack for Minecraft Java Edition] – feedback.minecraft.net It contains several experimental and work-in-progress features, most of which were eventually released in [[Java Edition 1.18]]. Its first release coincided with the announcement that [[Caves & Cliffs]] would be split into two major updates.{{snap|21w15a|April 14, 2021}}{{Mcnet|a-caves---cliffs-announcement|A Caves & Cliffs announcement|April 14, 2021}} The data pack was eventually superseded by [[:Category:Java Edition 1.18 experimental snapshots|experimental snapshots]] as changes that are too large for a data pack were introduced.{{Mcnet|new-world-generation-java-available-testing|New world generation in Java available for testing|July 13, 2021|Henrik Kniberg}} == Features == ; Items * [[Bundle]]s can be crafted once again. ; General * The [[height limit]] has been expanded 64 blocks up and 64 blocks down to a total of 384 blocks, with Y=319 being the limit upward and Y=-64 being the limit downward. ; World generation * Deepslate [[ore (feature)|blob]]s no longer generate above Y=0. * Diorite, granite, and andesite blobs are larger and more spherical, but less common. * Underground generation has been extended 64 blocks down to go along with the downward height expansion. ** [[Deepslate]] makes up a majority of the expanded area, with the stone above gradually transitioning to it from Y=-1 to Y=-7 until it is completely replaced by deepslate at Y=-8. *** Certain types of ores and structures still generate in the deepslate layer, as well as [[tuff]]. *** [[Dirt]], [[gravel]], [[diorite]], [[granite]], and [[andesite]] do not generate in this layer. ** [[Lava]] replaces air below Y=-53 instead of below Y=11. ** The [[bedrock]] layer has been moved down to Y=-64. * [[Fossil]]s are able to generate at any height instead of just between Y=40 and Y=49. ** Fossils below Y=0 generate with deepslate diamond ore instead of coal ore. * [[Cave]]s have been completely overhauled. ** Now stretch down to Y=-59. ** New [[noise cave]]s, coming in three forms: cheese, spaghetti, and noodle. *** Cheese caves have large stone columns stretching from the bottom of the cave to the top. **** Very large, often large enough to fly through with [[elytra]]. **** Abundant with [[spring]]s, aquifers, and [[ore]]s. *** 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. ** Contain [[aquifers]], bodies of [[water]] with different heights, independent of sea level (Y=63). *** Only used below Y=31, meaning any noise caves between Y=31 and Y=63 are flooded with water. *** Aquifers below Y=0 sometimes generate with lava instead of water. ** The original [[carver]]s still exist with their generation slightly tweaked to add more variation and to better blend in with noise caves. ** New crevice carvers, which are deep, long cracks in the ground that are thinner and straighter than [[canyon]]s. * [[Ore vein]]s, long and rare formations of [[ore]] and rock, have been introduced. [[File:21w18a approximate ore distribution.jpg|thumb|300px|The new ore generation in the data pack.]] * Changed the generation of all ores, making them have a spread value like [[lapis lazuli ore]]. Some still retain a linear generation alongside a spread generation. ** [[Copper ore]] generates between Y=0 and Y=96, and uses spread like all other ores. It peaks at Y=48. ** [[Emerald ore]] generates above Y=32 as a spread, peaking at Y=256 and decreasing in quantity as the [[altitude]] decreases. ** [[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. ** [[Iron ore]] attempts to generate three times: once as a spread peaking at an altitude of Y=256, generating above Y=128; 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=64. ** [[Gold ore]] generates between the altitudes of Y=-64 and Y=32, peaking at Y=-16. The extra gold that generates in the [[badlands]] biome was left untouched. ** [[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]] generates below Y=16 as a spread, peaking at Y=-64 and decreasing in quantity as the altitude increases. == History == {{HistoryTable |{{HistoryLine|java}} |{{HistoryLine||1.17|dev=April 14, 2021|slink=https://www.minecraft.net/en-us/article/minecraft-snapshot-21w15a|The Caves & Cliffs Prototype Data Pack was first publicly made available to coincide with the release of [[21w15a]]. |The data pack currently contains all the world generation changes from [[21w06a]] to [[21w14a]] that were reverted in this snapshot.}} |{{HistoryLine|||dev=April 21, 2021|slink=https://www.minecraft.net/en-us/article/minecraft-snapshot-21w16a|The Caves & Cliffs Prototype Data Pack has been updated for [[21w16a]]. |[[Ore vein]]s have been added. |[[Aquifer]]s below Y{{=}}0 are sometimes filled with lava instead of water.}} |{{HistoryLine|||dev=April 28, 2021|slink=https://www.minecraft.net/en-us/article/minecraft-snapshot-21w17a|The Caves & Cliffs Prototype Data Pack has been updated for [[21w17a]]. |[[Noodle cave]]s have been added. |[[Ore vein]]s are now slightly smaller, rarer, more clumpy, and have a chance to contain a [[Block of Mineral#Raw Metal|raw metal block]].}} |{{HistoryLine|||dev=May 5, 2021|slink=https://www.minecraft.net/en-us/article/minecraft-snapshot-21w18a|The Caves & Cliffs Prototype Data Pack has been updated for [[21w18a]]. |[[Carver]]s can generate below Y{{=}}0 in ocean biomes. |[[Noodle cave]]s no longer generate above Y{{=}}30. |The minimum size of noodle caves and carvers has been increased. |[[Deepslate]] blobs no longer generate above Y{{=}}0. |[[Ore vein]]s are slightly rarer and smaller on average, and [[Block of Mineral#Raw Metal|raw metal block]]s are more likely to be found in them. |[[Copper ore]] generation has been slightly reduced. |Smaller [[iron ore]] blobs can additionally be found between Y{{=}}-32 and Y{{=}}64. |Larger iron ore blobs are now slightly less common.}} |{{HistoryLine|||dev=May 12, 2021|slink=https://www.minecraft.net/en-us/article/minecraft-snapshot-21w19a|The Caves & Cliffs Prototype Data Pack has been updated for [[21w19a]]. |[[Bundle]]s and [[candle]]s still have a crafting recipe after they were both made hidden in the base game.
