This article is about the modern custom world type. For the world type before Java Edition 1.13, see Old Customized. For the Easter egg dimensions in Java Edition 20w14∞, see Java Edition 20w14∞ § World generation.
"Custom world" redirects here. For creating custom dimensions, see Custom dimension. For controlling world generation using data packs, see Custom world generation.
Information icon
This feature is exclusive to Java Edition. 

Custom is a world type that allow users to change the generation of the Overworld, Nether, and End dimensions as well as the ability to create custom dimensions. It is edited using a JSON file that is imported on the world creation screen.

Access

Custom world generation works using JSON files, which need to be imported before world creation.

In the world creation menu, go to more options and select the "Import World" option. Then, select a world generation JSON file. A warning appears saying that custom worlds are experimental. Click "Yes" to continue.

The only way to access added dimensions is through commands, such as /execute in <dimension name> run tp @s ~ ~ ~, which teleports the player to the specified dimension (see § JSON format).

JSON format

Instructions: explanations on each component of the JSON file. Useful sources: [1], [2]

Custom generation files take the following format:

  • The root tag.
    •  bonus_chest (Boolean): Whether the world has a bonus chest or not (equivalent to the "Bonus chest" option).
    •  generate_features (Boolean): Whether structures should be generated or not (equivalent to the "Generate structures" option).
    •  seed (integer): The numerical seed of the world.
    •  legacy_custom_options (string): The custom world preset that was used to generate the world when it was an old customized world. Exists only for old customized worlds.
    •  dimensions: A list of the dimensions in this world where the key is the namespace ID of the dimension.
      • A dimension. The dimensions minecraft:overworld, minecraft:the_nether and minecraft:the_end are required for a well functioning world. Any other namespaced ID is allowed for custom dimensions.
        •  generator: Generation settings used for that dimension.
          •  type (string): The ID of the generator. Can be minecraft:flat for a superflat dimension, minecraft:noise for noise generation, or minecraft:debug for a debug dimension.
          • Other compounds (see below)
        •  type: This can be a list of options for the dimensions, the namespaced ID of a dimension type file in a data pack, or one of the four default dimension types (minecraft:overworld, minecraft:the_nether, minecraft:the_end, minecraft:overworld_caves).
          • Custom dimension/Data

Generator types

    •  type: The ID of the genarator. One of noise, flat, or debug.
      If  type is minecraft:noise, additional fields are as follows:
    •  settings: The noise settings used in this generator. Can be set to an ID of noise settings, or a object of noise_settings.
    •  biome_source: Settings dictating which biomes and biome shapes.
      •  type: The type of biome generation. One of multi_noise, fixed, checkerboard, or the_end.
        If type is multi_noise(3D biome generation used in the nether, and in the overworld in snapshot 21w37a and after.) , additional fields are as follows:
      •  preset: (mutually exclusive with  biomes) An ID or an object of a multi-noise biome source parameter list.
      •  biomes: (mutually exclusive with  preset) (Cannot be empty) A parameter list of biomes, including their IDs and target noise parameters.
        • : A biome and its properties.
          •  biome: The biome ID. A single biome ID may be repeated several times with different parameters.
          •  parameters: Represent optimal intervals for where the biome should be placed. These values do not affect the generation of terrain within biomes, instead, they only affect where the game chooses to place biomes. Thinking of a six-dimensional space, in the space these intervals are defined for biomes. If the six parameters at a location based on the noise router in noise settings fall into an interval, the corresponding biome is generated here. If the six parameters at a location do not fall into a defined biome interval in this list, it uses the closest biome interval to the 6D parameter point, in order to form a transition between biomes. Parameter combinations should be unique in the biomes list.
            • Noise parameter for biome (See Biome for usages of each parameter in vanilla game)
        If type is the_end(Biome generation used in the end with biome minecraft:the_end in the center and other end biomes around) , no additional field.
        If type is fixed(single biome) , additional fields are as follows:
      •  biome: The ID of the single biome to generate.
        If type is checkerboard(A biome generation in which biomes are square (or close to square) and repeat along the diagonals) , additional fields are as follows:
      •  biomes: A list of biomes that repeat along the diagonals. Can be a ID of biome or a tag of biome, or a list of biome IDs.
      •  scale: (optional, defaults to 2) Value between 0 and 62 (both inclusive). Determines the size of the squares on an exponential scale.
      If  type is minecraft:debug(used for Debug world generation) , no additional fields.
      If  type is minecraft:flat(used for Superflat world generation) , additional fields are as follows:
    •  settings: Superflat settings.
      • Flat generation settings


Defaults

Moved to Custom world generation#Noise settings

Noise generator preset defaults

These are the settings used by the 6 presets available for the minecraft:noise generator.

Structure defaults

These are the default values for all namespaced structures. Every preset uses the same values for all of these structures, with the exception of minecraft:ruined_portal.

*Placeholder values, have no effect

**Salt values aren't used for theses structures; changing them produces no effect }}

Biome parameter defaults

These are the default values used for each biome in the multi_noise biome_source. Interestingly, although only the values for nether biomes are accessible through a preset, several overworld biomes have default values as well.

Type defaults

These are the settings used by the 3 dimensions present in Vanilla and the additional Overworld Caves settings provided by Minecraft.

Default settings

The following is the settings for an exported default Minecraft world.

Expanded default settings

This file contains the same settings used to produce a default world, but with all of the presets expanded to their default values. Note that there is a bug that makes it impossible to create the ender dragon fight without using the dimension type preset minecraft:the_end, as the flag that creates the fight is hardcoded and not accessible through JSON. However, it is otherwise identical to the default world.

Custom superflat dimension

Custom superflat dimension

An overview of a world made with the adjacent settings.

This dimension is a Superflat world with a layer of grass on four layers of coarse dirt on top of five layers of basalt. The entire world is full of village houses as spacing is set to 3 (default: 32) and separation is set to 1 (default: 8). The words starts by default at time 1000.

An '''explorer map''' is a special [[map]] used to aid in finding rare [[generated structures]], including [[woodland mansion]]s, [[ocean monument]]s, and [[buried treasure]]s.

== Obtaining ==
=== Trading ===
Apprentice-level [[cartographer]] villagers sell ocean explorer maps for 13 emeralds and a compass. Journeyman-level cartographer villagers sell woodland explorer maps for 14 emeralds and a compass.

{{IN|java}}, if the cartographer is in [[the Nether]] or [[the End]], either spawned or transported, the trades for the map do not unlock. However, {{in|bedrock}}, the cartographer trades for the map are unlocked, but the purchased map shows the same layout as in the corresponding dimension and shows no destination structure, but if cartographer trades are unlocked in an old world type (prior-1.11.0), the game stops ticking.

In ''Java Edition'', each cartographer sells its own unique explorer map that points to a different location than other cartographers. Purchasing another explorer map from the same cartographer results in the same explorer map. In Bedrock Edition, a cartographer sells an explorer map that points to the nearest location, regardless of whether it is explored or previously mapped by another cartographer.<!-- start to glitched out-->

=== Chest loot ===
Treasure maps, in contrast to explorer maps, generate in underwater ruins or in shipwrecks.
{{LootChestItem|buried-treasure-map}}

== Usage ==
[[File:Explorer Map Comparison.gif|thumb|217px|Unexplored and partially explored maps.]]

{{See also|Map#Mapping|Map#Map content}}

=== Locating structures ===
There are three types of explorer maps: woodland, [[ocean]], and buried treasure. The maps differ from a normal map, in that it shows the area's land-water outline, with an orange striated (striped) texture for water<ref>Specifically, biomes in the "water_on_map_outlines" [[Tag#Biomes|biome tag]].</ref>, and the blank map texture for land. The maps show a section of land that contains a [[woodland mansion]], [[monument]] or [[buried treasure]] respectively. This may not be the nearest such [[structure]] to the [[player]]. The structures are displayed as a small icon. If the player icon is smaller than it would be on a normal map, that means the player is a great distance away. When the player is less than 1027 blocks away from the map border, the icon returns to the proper size. When the player reaches the map's area of land (512×512), the [[map]] fills in like a normal map.

The basic functions of a buried treasure explorer map are similar to that of the other two. However, instead of showing the structure icon on the map, it shows a red X instead. The [[buried treasure]] structure is located on the same X and Z coordinates as the middle of the X (the player marker may need to be aligned with the bottom of the middle 2×2 pixel square of the X). To locate the [[chest]] spot, hold the treasure map with both hands, not in the offhand slot.

}}

The parts of the world that have already been explored and mapped are copied, and newly explored areas appear on both instances. In Creative mode, cloned explorer maps can be obtained by pick blocking on the explorer map displayed on [[item frames]] (the map needs to be out of the [[player]]'s inventory when using pick block, or else that map moves into the active hotbar slot).

=== Metadata ===
{{see also|Bedrock Edition data values}}
{{IN|bedrock}}, the item [[Data value]] distinguishes explorer maps from one another:

{{:Map/DV}}

=== Item data ===
An explorer map differs from a map in that its <code>display</code> tag is set, which includes a <code>Mapcolor</code> and a <code>LocName</code>; also its <code>Decorations</code> list includes an entry for its target monument, mansion or buried treasure. Its [[Map item format#map_<#>.dat format|map item entry]] is identical to that of a normal map, except that by the time the player sees it, its <code>colors</code> byte array is pre-filled with explorer maps' characteristic land-water boundary lines and water shading.

<div class="treeview">
It should be noted that this additional data is stored in the Cartographer's NBT data and in the inventory item's NBT data, and not in the map file (e.g. <samp>map_0.dat</samp>). If the [[player]] were to use the {{cmd|give}} command to give themselves a map with the same map ID as an existing explorer map, it would still have the Ocean Monument or the Woodland Mansion icon on the map, but it would simply be named "Map" instead of, for example, "Ocean Explorer Map".
* {{nbt|compound}} Item data
** {{nbt|compound|tag}}: 
*** {{nbt|compound|display}}: How the map looks in an item slot. See also [[Player.dat_format#Display Properties]].
**** {{nbt|string|Name}}: The name the map is given. In this case, they are localized strings: either <code>{"translate":"filled_map.monument"}</code>,<code>{"translate":"filled_map.mansion"}</code> or <code>{"translate":"filled_map.buried_treasure"}</code>.
**** {{nbt|int|MapColor}}: Color codes are calculated from the Red, Green and Blue components using this formula:<br>'''<span style="color:red">Red</span>[[wikipedia:Logical shift|<<]]16 + <span style="color:green">Green</span><<8 + <span style="color:blue">Blue</span>'''.<ref group=note>For positive values larger than 0x00FFFFFF, the top byte is ignored. All negative values produce white.</ref> Monument maps use 3830373, which is {{color swatch|58|114|101}}. Mansion maps use 5393476, which is {{color swatch|82|76|68}}. Buried treasure explorer maps do not use a color code.
*** {{nbt|list|Decorations}}:
**** {{nbt|compound}}: One of these for each icon on the map. Explorer maps always have at least one representing their target.
***** {{nbt|string|id}}: An arbitrary unique string identifying the decoration. For explorer map target structures, this is "+".
***** {{nbt|double|rot}}: The rotation of the icon. For explorer map target structures, this is always 180.
***** {{nbt|byte|type}}: The ID of the [[Map#Map icons|map icon]]: 8 for a mansion map, 9 for a monument map, 26 for a treasure map.
***** {{nbt|double|x}}: The world x-coordinate of the target structure icon.
***** {{nbt|double|z}}: The world z-coordinate of the target structure icon.

== Issues ==
{{Issue list}}

== Trivia ==
* When a [[cartographer]] generates the trade offers for the explorer maps, it chooses the location of one of the nearest structures of the respective type ([[monument]] or [[woodland mansion]]).
* For the reason above, explorer maps obtained from one cartographer are always the same. Also, if two cartographers unlock the explorer map trades approximately at the same place and at the same time, the map locations are usually identical. This sometimes also happens when finding multiple treasure maps from [[ocean ruins]].
* Explorer maps fill as the [[chunk]]s are generated, rather than when the [[player]] holds them while in the area; leaving an explorer map while exploring the area still fills the map.
* Buried treasure explorer maps are named ''Buried Treasure Map'' {{in|java}} while {{in|bedrock}}, they are named ''Treasure Map''.
* It is possible for a cartographer to give a monument or woodland mansion explorer map for areas where the [[generated structures|structures]] would have spawned in the world, but were unable to as a result of terrain generation. As a result, explorer maps, unfortunately, don't always guarantee that a structure exists at the purported location. This is most common with woodland mansion explorer maps, due to its generation algorithm.
* On [[Bedrock Edition]], inventory editors and add-ons can be used to create Explorer Maps that lead to any structure.

A '''heart of the sea''' is a rare [[item]] that can be crafted into a [[conduit]].

== Obtaining ==
The heart of the sea must be found. It cannot be crafted or obtained by trading, making it a [[non-renewable resource]].

A heart of the sea is obtained from a [[buried treasure]]. The location is marked with a noticeable red X on a [[Explorer Map|buried treasure map]], which is found in [[Ocean_Ruins|ocean ruins]] and [[Shipwreck|shipwrecks]]. Feeding [[raw cod]] or [[raw salmon]] to a [[dolphin]] causes the dolphin to swim toward the nearest [[buried treasure]], [[shipwreck]], or [[ocean ruins]].

A '''minecart with furnace''' is a [[furnace]] inside a [[minecart]]. It can be powered with [[coal]] or [[charcoal]] to propel it across a [[rail]] line for a limited time, which can be used to move other minecarts.

==Obtaining==
Minecarts with furnace can be retrieved by attacking them, and by doing so it drops as an [[item]].

===Crafting===
{{Crafting
|Output= Minecart with Furnace
|type= Transportation
|Furnace|Minecart}}

==Usage==
Minecarts with furnaces are placed in the same way as other minecarts. It does not have a graphical user interface, unlike a [[furnace]].

Minecarts with furnaces can be powered, done by feeding fuel ([[coal]] or [[charcoal]]) into the furnace minecart with the {{Control|use}} button. The fuel is consumed immediately and it starts to move in the same direction the player clicked toward. Pressing {{Control|use}} always turns it to that direction, even when not holding coal.

Any piece of fuel, added at any time, increases the total range by an additional 3600 ticks (equal to 180 seconds or 3 minutes).  The upper limit is 32767 ticks, approximately 27 minutes.

When powered, minecarts with furnaces cover 240m per minute (about 4 m/s, slightly slower than walking speed) or 720m per piece of coal. They do not accelerate beyond this speed when going downhill or on active [[powered rail]]s, and as long as they remain powered, they do not slow down when going uphill, on inactive powered rails, or when pushing or pulling other minecarts.

If a powered furnace minecart is derailed and then pushed back onto a rail, it starts moving again in the direction it came from, so they are not easily turned around in this state unless a player is nearby to redirect it with {{Control|use}}.

Minecarts with furnaces can climb up steep inclines while pushing other minecarts as long as they have fuel. If a minecart with furnace reaches a slope while pulling another minecart, the pulled minecart is switched to the forward position so that it can be pushed along the slope instead of pulled.

When a minecart with furnace bumps into another minecart or multiple minecarts, the other minecarts are pushed forward with great speed. The furnace minecart continues on with its own speed. Because of this speed difference, some of the minecarts may end up inside unloaded chunks on straight tracks.

===Train mechanics===

[[File:FurnaceMinecartTrain.png|thumb|right|A Minecart train powered by furnace [[Minecart|minecarts.]]|alt=]]
A furnace minecart can be made to pull up to four other minecarts. All minecarts in this train move at the constant speed of the furnace minecart.  Trains are formed when a minecart is pushed into the back of a powered furnace minecart or a short-enough train.  These shunts are fragile at best and easily come undone, but some methods are stronger than others.  For example, pushing a minecart into a furnace minecart and then powering the furnace gives a weaker shunt than pushing the furnace minecart into the other minecart against a wall, and then powering the furnace in the other direction.

A high-speed minecart running into the back of a furnace minecart going in the same direction automatically creates a weak shunt with it, pulling it along.

Pulling a minecart with TNT causes it to explode.

{| class="wikitable"
|+Pulled minecart/Shunt behavior
!Condition
!Result
|-
|Furnace loses power/speed||Shunt comes undone
|-
|Entity bumping besides those part of the train||Jettisoned forward
|-
|Upward sloped track||Jettisoned forward
|-
|Downward sloped track||Jettisoned forward (strong shunt) or shunt comes undone (weak shunt)
|-
|90° turn in track||Jettisoned backward
|-
|Turn toward north/south or east/west that is not the direction the train was shunted in||Train derails
|}

When a train comes to a turn, the shunt comes undone with the pulled minecart jettisoned backward. The correct way to make such a turn is having the shunt undone before a turn, and then make the two rejoin on a straight rail later by having the pulled cart catch up with the minecart with furnace.<ref name=mango/>

Since the train runs slower on a fully powered track than a normal minecart (~5 m/s compared to 8m/s), a train pulled by an unpowered furnace minecart is ideal for AFK farms involving breaking or placing blocks like [[nether wart]].<ref name=mango>{{YouTubeLink|1=pRLiAQfhTG8|2=Why The Furnace Minecart Isn't As Useless As You Think|3=ilmango}}</ref>

==Properties==
The coal is not stored as an item in the entity, but in the object data in the fuel property as a time in ticks. ''Fuel'' is a short value, i.e. a maximum of 32767 ticks, which is about 27 minutes. However, {{cmd|/summon furnace_minecart ~ ~ ~ {Fuel:32000} }} alone doesn't make it go since it doesn't have a direction. It can be right-clicked on a track to give it a direction, or it can be summoned with the properties ''PushX'' and ''PushZ'' set, which are responsible for the direction. The <code>Motion</code> property of every entity allows for movement of the minecart, but it does not direct the minecart to move on its own.

==Sounds==
{{Edition|Java}}:<br>
Minecarts with furnaces use the Friendly Creatures sound category for entity-dependent sound events.<ref group=sound name=rollsource>{{bug|MC-42132}}</ref>

==Trivia==
*The minecart with furnace is excluded from {{els|be|3ds}} on purpose. In a tweet, [[Jeb]] considered removing it from {{el|je}}.<ref>{{tweet|jeb|699241247391772672|I think we will phase out the furnace minecraft ''(sic)''|15 Feb 2016}}</ref>
**When converting a [[Legacy Console Edition]] world to a [[Bedrock Edition]] world, any present minecarts with furnaces are converted into a normal minecart.
**Despite the above-described poor standing of the minecart, it was most recently briefly featured in an animation in the [[Minecraft Live 2022]], where one was depicted as moving a train of about 20 minecarts at a higher than normal speed.

A '''medicine''' is a type of [[potion]] that cures the specified [[effect]] instead of applying it.

== Obtaining ==

=== Brewing ===
Cures are brewed from awkward potions using different [[element]]s.{{only|bedrock|education}} These drinks remove the specified effect when drank, and cannot be modified into splash, lingering, extended or enhanced versions.

== Usage ==

Each type of medicine has an associated effect that it can cure (see {{slink||Brewing}} for details). Players can drink the medicine only if they have the corresponding effect. Drinking the medicine eliminates the effect. Although medicine does not resemble [[potion]]s, the player still gets the [[glass bottle]] back.
