Varje specifik grupp av block formade i Minecraft baserat på kodning är en del av en naturlig struktur.

Övervärlden[edit]

Övervärlden innehåller många genererade strukturer på en stor variation av skalor.

Terräng[edit]

Landskap bestämmer höjden och formen av en värld. På det här steget är marken gjord endast av sten och vatten i alla tomma utrymmen under lager 63, med undantag av strukturer.

Berg[edit]

Berg är stora kullar med extrema klippor. Berg kan ha grottor genom sig. På en amplified är berg extremt vanliga i alla landskap utom hav och träsk.

Svävande öar[edit]

Svävande öar är strukturer som svävar i luften och inte tar i marken, havet, kullar eller klippor. Svävande öar är normalt bara bitar av jord och sten nära klippor, men i sällsynta fall kan de vara stora och de kan till och med ha träd och källor på sig. Svävande öar hittas oftast i extrema kullar, snöiga slätter och svampöar, men kan bli hittade var som helst. Svävande öar är väldigt vanliga i amplifiedvärldar.

Hålor[edit]

Hålor är motsatsen till svävande öar. De ser ut som grottor men de har inget att göra med grottgenerering, utom att de kan vara anslutna till dem. När det är många överhäng nära varandra skapas en håla. De har exakt samma golv som terrängen ovanför, beroende på landskap, inte som grottor. Grottor har inget specifikt golv. Gräs kan genereras inuti också, även fast det inte finns något ljus. När de genereras under havsnivån är de fyllda med vatten. De är extremt sällsynta i en vanlig värld, men de kan bli hittade i en anpassad värld.

Kullar[edit]

Kullar är slumpmässigt genererade bitar av mark i världen. Kullar är som trappor, Det finns nästan alltid en plats på varje nivå där man kan ta sig till nästa, vilket betyder att spelaren kan klättra en nivå i taget tills hen når toppen. Fall där det inte är så är sällsynta.

Stränder[edit]

Stränder genereras vid haven och täcker alla närliggande kustremsor. Det finns tre varianter: sandstränder, grusstränder och stenstränder. Under sanden på sandstränder finns det sandsten. Grusstränder har ingenting under, vilket skapar faror som att falla ner i grottor under dem. Stenstränder har klippor nära havet.

Ytan[edit]

Ytlager[edit]

Lagrena högst upp i terrängen är ändrat till landskapsberoende material: oftast gräsblock och jord, eller sand i öknar och stränder. sandsten finns under sand. Podzol hittas i megatajga, och röd sand i mesalandskap.

Basin[edit]

Istället för att ändras till jord eller sand blir ibland lagret högst upp borttaget och skapar en 'basin' av sten. De har en viss likhet med en geologisk 'sköld' (ett område They bear some resemblance to a geological 'shield' (an area of stable rock that has been exposed to prolonged erosion due to its very old age; it is distinct from the geological term "basin"). They seem to be more common in forest or plains, and are occasionally seen filled with water. Commonly, minerals can be found in these, generally coal ore and iron ore. If generated in a Mesa biome in Pocket Edition, gold ore can also be seen.

Water bodies[edit]

Ocean[edit]

Oceans/Seas are huge bodies of water with every single water tile being a source block. The ground can rise high enough to produce small, relatively barren islands. Prior to the Adventure Update, oceans were generated as part of the terrain generation algorithm, but since then, they are part of the ocean biome.

Deep oceans have a chance to spawn with an ocean monument.

River[edit]

Rivers are long "strands" of water that cut through or separate biomes. They do not have a current. Patches of sand and gravel are seen commonly dotting the banks of the rivers, and clay settled at the very bottom. In some cases, rivers will generate higher than normal, producing a dry riverbed, sometimes with occasional small water patches.

Lake[edit]

Lakes are small bodies of liquid. Water lakes, which are small pools of water springs, can generate above sea level or inside caverns. They can also generate isolated underground, connected to no other structures whatsoever. When in a winter biome, these small lakes are never initially frozen but will turn to ice if exposed. The lakes can also be composed of lava; however, lakes of lava are much rarer. Lava lakes found at the surface are surrounded by stone (which can be replaced by ore veins such as dirt, gravel and coal). Both types of lake generate with a small air pocket above them, which may result in floating sand, floating snow cover or even the top 2/3rds of trees above the lake. Lava lakes may cause trees to burn away.

Large structures[edit]

Cavern[edit]

Caverns are caves and tunnels that are automatically generated under the ground in various places. Caverns are composed mainly of stone, and expose large amounts of ores and igneous stones. When caves are generated so their entrances are located in a mesa or desert biome, some of the sand around cave entrances can be found compressed into the biome's respective sandstone.

Ravine[edit]

Ravines are tall, long cracks of air, usually measuring around 30 to 50 blocks in height, 84 to 112 blocks long and no more than 7 blocks wide. Ravines can have small ledges along the top. They can be found at levels 20 to 68, sometimes appearing on the world surface or underwater, forming canyons. They can go very deep underground, sometimes spawning slimes or exposing diamond ore. If they reach deep enough, they may also be floored by the lava lakes at level 11. In the Amplified world type, ravines can reach from surface level to bedrock. Ravines can also be found in oceans or rivers having a waterfall from the river/ocean falling into them.

Ravines can connect to caves, dungeons, abandoned mineshafts, and any other generated structures. Due to the large surface area of their walls, ravines often have water and/or lava flowing down them (from springs in the walls, underground lakes, or even openings to the sea).

Abandoned mine shaft[edit]

Abandoned Mineshaft
Minecraft Mineshaft.png
Biome(s)

Any

Consists of

Abandoned mineshafts are structures generated underground which consist of branching mining tunnels with wooden supports and broken rails passing through it. Cave spider spawners can be found in mine shafts. Open areas generate with oak wooden bridges instead of leaving floating platforms. They contain minecarts with chests that may have rare items such as diamonds and horse armor. They may also contain iron ingots, coal, pickaxes, and other useful items. They are likely to expose veins of coal, iron, lapis lazuli, gold ore, and rarely, emerald and diamond ore.

Stronghold[edit]

Strongholds are structures that contain multiple rooms, doors and other aspects (some of these rooms include libraries, fountain rooms, dungeon-like rooms, etc.). There are 128 per world . Stone brick, mossy stone brick, cracked stone brick, doors, iron bars, monster eggs and stone slabs are the materials that make up the strongholds. They also contain silverfish, which one should be careful of when digging around in strongholds. Portals to The End are found in specific rooms in strongholds. Chests may be found containing items such as books, redstone, ender pearls, apples, bread, compasses, iron tools/armor, and diamonds. Strongholds can be found by right clicking an eye of ender, which will be thrown into the air and point the direction where the End portal is, showing the way to the stronghold.

Small structures[edit]

The quantity of most of these features (aside from dungeons, mineral veins, and springs) is biome-dependent; not all features can be found in every biome.

Dungeon[edit]

Dungeon

Biome(s)

Any

Can generate
post-generation

No

Dungeons are small, mostly underground, one-room spaces bordered by moss stone and cobblestone, and typically contain chests with rare items, and a hostile monster spawner in the center. Dungeons generate with either a zombie (50% chance), skeleton (25% chance), or spider (25% chance) spawner. Occasionally a player may find that the spawner is covered with gravel and will be harder to reach, yet the mobs can still spawn with the gravel around it. The chests may contain rare valuables, such as music discs, enchanted books, saddles, horse armor, and golden apples. Rarely, multiple dungeons can generate next to each other. Dungeons generated in a desert can sometimes be visible from the surface due to the sand falling down.

Mineral vein[edit]

Mineral vein
Mineral vein.png
Biome(s)

Coal, iron, gold, redstone, diamond, lapis lazuli: Any
Emerald: Extreme Hills
Nether quartz: the Nether

A mineral vein is a natural deposit of ores. Players can come across these veins in caverns or anywhere where there is natural stone. Underground deposits of dirt and gravel are generated in this step, followed by the more precious ores: coal, iron, gold, redstone, diamond, emerald (in extreme hill biomes) and lapis lazuli. They can only form in stone, and do not replace each other or any other block. However, there is one exception: other ores can replace andersite, diorite and granite. Note that two or more mineral veins can form next to each other and make it look like a mineral vein made of more than one material.

Tree[edit]

Tree
Oak Tree.png
Biome(s)

Any (but not deserts or mesas (except for mesa plateau Fs))

Trees are common structures created both during world generation and by players (grown from saplings). They are made of wood and leaves. Tree sizes range from small trees that can be fully harvested from ground level, to large trees that may require several minutes to harvest.

Huge mushroom[edit]

Huge mushroom
Huge Red Mushroom.pngHuge Brown Mushroom.png
Biome(s)

Mushroom Island, Roofed Forest or the Swamp (Pocket Edition Exclusive)

Huge mushrooms are structures that only naturally occur in mushroom island biomes and roofed forest biomes. They are composed of mushroom stalks and either red or brown colored blocks for the cap. They can be grown outside mushroom islands by fertilizing red or brown mushroom with bone meal, or can be generated with mycelium.

Spring[edit]

Springs are randomly generated blocks of either lava or water that act as a source of their respective material. While both can be found on the vertical side of stone blocks above the surface, lava springs are more often found underground beneath layer 32 in caverns.

Desert well[edit]

Desert well
Desert Well.png
Biome(s)

Desert

Consists of

These well-like structures built of sandstone blocks and slabs generate only in the desert biome. They have a 1/1000 chance to be generated in any desert chunk, which makes them a rare sight. It is possible for a well to generate around a cactus. The well structure will still spawn with the "Generate Structures" option disabled.

Moss stone boulder[edit]

Moss stone boulder

Biome(s)

Mega Taiga

These structures are meant to represent boulders, made entirely of moss stone. The formation of these structures vary possibly infinitely. They can be found dotted around areas of the mega taiga biome. Due to the wide variety in shape they often appear to just be a patch of moss stone on the ground rather than a boulder. Moss stone boulders are quite rare, due to the mega taiga biome's rarity


Ice spike[edit]

Ice spike
Ice World Spikes.png
Biome(s)

Ice Plains Spikes

Ice spikes are tall spires made of packed ice. The spikes can only be found in the ice plains spikes. There are two variants of ice spikes: one is short and thick, and the other is extremely tall and thin.

Buildings[edit]

Buildings are naturally generating structures that form above ground. They can contain valuable treasure, but traps and puzzles as well.

Village[edit]

Village
Village.png
Biome(s)

Plains, desert, savanna

Villages are generated in desert, plains and savanna biomes and are a site for villagers, with whom the player can trade. They are composed of a random selection of various buildings and farms. There is always exactly one well, other buildings can be any of several different houses, single or double farms, blacksmith's shop, library, butcher's shop, or church. Villages are built with different materials depending on their biome; villages in plains and savanna biomes are comprised of oak wood, oak planks and cobblestone, and villages in deserts are built with varying types of sandstone. Villages may generate partly submerged in water. This results in some of the path being made of wood (Pocket Edition exclusive). The villagers move about in the area around the village, retreating indoors at night and during storms. Villages have three-block wide paths to join all houses.

Desert temple[edit]

Desert temple
Desert Temple.png
Biome(s)

Desert

Desert temples, also known as pyramids, are found in deserts. They mainly consist of sandstone and stained clay. In the middle of the temple is a block of blue stained clay, which if destroyed, reveals a deep, hidden chamber underneath, where players can find 4 chests, which can contain valuable loot, and a stone pressure plate trap connected to a 3×3 grid of TNT. Treasures found in the chests include emeralds, diamonds, iron ingots, gold ingots, rotten flesh, enchanted books, and bones. While rotten flesh, bones and gold ingots are found frequently, other treasures are not as common.

Jungle temple[edit]

Jungle temple
Jungle Temple.png
Biome(s)

Jungle and jungle M

Jungle temples are found in jungles, and mainly consist of cobblestone and mossy cobblestone. There are three floors, the bottom floor containing a chest and a puzzle. The chest is found through a corridor which contains hidden tripwires that triggers a dispenser to shoot arrows at the player. The player must carefully navigate through the corridor while triggering the tripwires. The puzzle is located at the opposite of the corridor and consists of three levers that must be pulled in the correct order to open a secret door which reveals another chest.

Witch hut[edit]

Witch huts generate in swamp biomes. Among all hostile mobs, only witches spawn in the 7x7x9 area inside and around the hut. There is one empty cauldron, one crafting table and one potted red mushroom inside each hut. However, in 1.8 the flower pot contains no mushrooms.

Ocean monument[edit]

Ocean monument
Ocean Monument.png
Biome(s)

Deep Ocean

Ocean monuments are underwater structures that spawn in deep oceans. They spawn in the shape of a pyramid with many randomly-generated rooms. They are composed of all three variants of prismarine and lit by sea lanterns. Eight gold blocks encased in dark prismarine can be found inside as treasures. Also, a random assortment of sponges may generate inside. Guardians and elder guardians spawn here.

Igloo[edit]

Igloos are structures that spawn in snowy biomes. They have consist of an igloo, and sometimes, a basement. In the basement there are a villager and a zombie villager, both of the same profession. They are locked up, so they aren't wandering around. The basement is accessible by removing one of the carpets to reveal a hidden trapdoor.

The Nether[edit]

The Nether, though equally vast, contains far fewer types of generated structures than the Overworld.

Lava sea[edit]

Lava seas are found at and below level 30 in the Nether. They make a large portion of the Nether, and are extremely common. They can stretch for hundreds of meters in any direction, and are usually bordered by netherrack (or more rarely soul sand). Even on far render distance, the player is rarely able to see the other side of the seas due to their vastness.

Nether fortress[edit]

Nether fortresses are very large complexes made mainly of nether bricks (with added nether brick fences and stairs to be found). Nether fortresses can often tunnel through netherrack, and the inside of the tunnels will be cleared of netherrack by the terrain generator. Blaze spawners and nether wart farms are only found in nether fortresses. Blazes, zombie pigmen and wither skeletons can spawn anywhere in the fortress. Nether fortresses have some chests. The chests with loot are usually generated in corners.

Glowstone cluster[edit]

Glowstone cluster
Glowstone Cluster.png
Biome(s)

Hell (The Nether)

Glowstone clusters are typically veins of glowstone that can be among the hardest natural materials to harvest that don't require digging. They form in coral-like structures on the underside of hanging Netherrack, so they are often found on the ceilings of the Nether, where they provide light along with the ever present lava.

Other things[edit]

There are areas of soul sand and gravel around layer 64, nether quartz ore veins and "hidden lava", which is a single block of lava in random places not visible without digging.

The End[edit]

The End is the most barren dimension, with only four types of significant structures.

The Island[edit]

Most of the End is a large, asteroid-like island composed entirely of end stone, floating in an endless void. The End also generates more islands about 1000 blocks away from the main island. These consist of large islands, about the size of the main island, and small ones, which are usually very thin and small.

Obsidian pillar[edit]

post-generation

No

Obsidian pillars, or obsidian towers, are tall, tower-like structures that generate in The End. No part of them are in the ground; there is no obsidian below the lowest block of obsidian that the player can see without digging. End crystals will spawn on top of each one to heal the Ender Dragon.

On the Console Edition, the pillars are generated in a circle around the fountain. Two of the end crystals are surrounded by iron bars, which must be destroyed before the crystal can be taken out.

Obsidian platform[edit]

The obsidian platform is a 5 by 5 square of obsidian that the player spawns once they enter The End. (Note that if the obsidian is destroyed, or if a block is placed on top of it, when the player or any other entity enters the End, the obsidian will be restored and any blocks on top of it will despawn.) Obsidian platforms mostly spawn far away from the island, making it tough to get there.

  • Sometimes the platform spawns inside a case of end stone. It will remove enough end stone so that the player can walk around.
  • Occasionally the platform will spawn in midair.
  • Very rarely, the platform will spawn on an obsidian pillar and have an end crystal on it.

End fountain[edit]

post-generation

Yes, when an Ender Dragon is defeated.

The exit end portal, in the shape of a fountain is found once the Ender Dragon is defeated, giving the player a way back to the overworld. This fountain is also the foundation of the Ender dragon egg. After entering the fountain, the Minecraft credits come on the screen, implying that you have "beaten the game" (despite the fact that the game never ends). You can skip these credits by pressing Esc. After the credits have finished (or after you skipped them), the player returns to the last bed they slept in (or their original spawn spot if the bed was obstructed). The fountain is also made of bedrock, making it indestructible.

On the Console Edition, the fountain is generated in between the Pillars, and already exists before the ender dragon is killed. The ender dragon will also fly above the fountain when the player approaches it, and spew Ender Acid. In addition, the ender dragon will defend the fountain from endermen every 3 minutes or so.

End gateway portal[edit]

post-generation

Yes, when an ender dragon is killed.

The end gateway portal is a portal to the outer islands of the End. It is a fast way to get there without bridging over or flying. It is generated after you kill the Ender Dragon. It will emit a purple beacon beam for a few seconds upon generation. You can get a new one each time you kill the ender dragon, with up to 20 created. It consists of the end gateway and two bulbs of bedrock. It is only accessible through ender pearls. When an entity enters, it will momentarily emit a yellow beam.

End city[edit]

End cities are structures that are naturally generated in the outer islands of the End. They are tall castle or tree-like structures constructed primarily of end stone bricks and purpur blocks and their variants. They are lit up by End rods. They are also the only places where shulkers can be found.

Chorus tree[edit]

post-generation

Yes, when a chorus flower is planted on end stone and left to grow.

Chorus trees generate on the outer islands of the end. They are shaped like tall and skinny trees. They consist of chorus plants and chorus flowers. A chorus flower will spawn at the top of each branch. They are the only source of chorus fruit and chorus flowers. You can grow a chorus tree by planting a flower on a block of endstone.

Technical details[edit]

Structures are generated for a given chunk after the terrain has been formed. The chunk format includes a tag called TerrainPopulated that indicates whether structures whose point of origin is in that chunk have been generated. If it is false or missing, they will be generated again. Structure generation is based on what is already in the chunk, so (for example) flagging a chunk that has already been populated for repopulation will approximately double the amount of ore in it.

When structures are generated, they can spill over into neighboring chunks that have been previously generated. Thus, a tree at the edge of the generated world (and probably only visible using external tools) may be overwritten by a lake before you reach it. It is also theoretically possible for two worlds generated with the same seed, from the same version of Minecraft, to differ slightly depending on the players' travel routes, because the order in which chunks are generated may determine which of two conflicting structures will overwrite or suppress the other.
