Superflat[JE only] or Flat world[BE only] is a world type or a vanilla world preset that replaces the normal varied terrain of the Overworld with a completely flat surface composed of multiple layers and set to a single biome.
A superflat world can be customized using presets, which change its layers and biome. In Java Edition, presets can also change the features and structures found in a superflat world, and an in-game menu allows players to fully customize the layers and the biome.
In Java Edition, superflat can also refer to a dimension's generator type, with which the completely flat terrain can be generated in a specific dimension. See also Custom dimension and Custom world preset.
In the default superflat world, the terrain consists of one layer of bedrock, two layers of dirt, and one layer of grass blocks, with the biome set to plains. In Java Edition, villages generate relatively frequently, and strongholds can also be found; in Bedrock Edition, no features or structures generate in flat worlds.
In the default superflat world, the surface of the world is completely flat and at Y=-60, except for villages and other structures if they are enabled. Mobs still spawn normally. Because of the low altitude of the world, slimes spawn frequently.
Superflat worlds allow the player to access the Nether and the End in the usual ways, which generate as normal.[1]
When creating a new world, the superflat generator can be changed to various presets or fully customized depending on the edition.
In Java Edition, upon selecting "Superflat" in the "World Type" button, the "Customize" button on its right becomes clickable. In the "Superflat Customization" menu, there are two buttons available to customize superflat worlds: the "Remove Layer" button, used for removing unwanted types of layers, and the "Presets" button, used for accessing the preset code string or selecting one of the nine default presets. Data packs can be used to customize the default presets or add new ones, see Custom world preset#Superflat Level Generation Preset for more information.
If the player can understand the preset code syntax, they can create presets of their own by entering valid information into the preset code box. The preset code can be highlighted and copied, allowing it to be shared with other players. Similar to how new worlds are shared through seeds, a preset code can be entered into this box to use it.
The preset code currently cannot fully describe a superflat level generation preset. Settings related to features and structures are inaccessible in the preset code. Using a preset code to recreate a world can only ensure that the blocks on each layer are the same, as well as the same biome, but cannot guarantee the same settings for features or structures. When using a preset code, the settings for features and structures are based on what default preset is currently selected on the list.
In Bedrock Edition, upon enabling "Flat world" in the "Advanced" settings tab, an additional setting allows the player to select a preset and view its block layers. Presets only affect the layers and the biome; terrain features and structures never generate in any of the presets.
There is no interface for further customization. However, custom flat worlds are possible internally, and can be generated by modifying FlatWorldLayers in the world's level.dat file using an external editor. This was used for converting custom superflat worlds from Legacy Console Edition to the console versions of Bedrock Edition.
The preset code is a string of numbers, semicolons(;), colons(:), commas(,), and asterisks(*). Each code has three main parts, divided by semicolons. They are:
.png){kind=link}
.png){kind=link}
minecraft:glass,minecraft:glass,minecraft:glass,minecraft:glass would give the same result as 4*minecraft:glass.village(size=0 distance=9) (in 1.13+ they have no effect). Multiple parameters are separated by spaces, rather than commas or semicolons.| Feature generation option | Parameters | Description | Biome |
|---|---|---|---|
| village | size distance |
Generates villages, provided they exist in that biome type. Extremely large size values and low distance values generate many villages tightly grouped together size determines the size of the village (default is 1, normal worlds have this set to 0, maximum is 65535). distance is the maximum distance between villages (minimum is 9, default is 32). |
Plains, Desert, Savanna, Taiga, Snowy Tundra, Snowy Taiga |
| mineshaft | chance | Generates mineshafts. They generate in midair if no terrain is present to cover them. chance determines how common mineshafts are (from 0.0 to 1.0, default is 0.01). Higher number, more common. |
All |
| stronghold | distance count spread |
Generates strongholds. distance determines how far strongholds are from the spawn and other strongholds (minimum is 1.0, default is 32.0). count is the number of strongholds that exist per world (default is 3). spread determines how concentrated strongholds are around the spawn (minimum is 1, default is 3). Lower number, lower concentration. |
All |
| biome_1 | distance | Generates biome-specific features. This enables igloos, jungle pyramids, desert pyramids, or witch huts. distance for the maximum distance between features (minimum is 9, default is 32). NOTE: desert pyramids (and potentially other structures) are not generated solely by biome_1, and "desert_pyramid" must be added to the syntax. Both "biome_1" AND "desert_pyramid" must be added to the syntax for pyramids to generate. Putting "desert_pyramid" in your syntax without "biome_1" causes issues, and attempting to /locate a desert pyramid without biome_1 enabled effectively breaks your world. This applies to 1.14+ and potentially earlier game versions. This option may also be necessary with igloos, jungle pyramids, ocean monuments or witch huts, requires testing. |
varies |
| dungeon | None | Monster rooms are generated, if possible. | All |
| decoration | None | Causes plants, ores, and similar features to be generated according to the biome type. Stone, dirt, grass, sand, or mycelium are required for most features. | All |
| desert_pyramid | None | Generates desert pyramids. | Desert (Hills) |
| lake | None | Generates water lakes, sometimes with sand and sugar cane depending on biome. | All |
| lava_lake | None | Generates lava lakes, with stone surrounding them. If all stone layers are removed in a preset that enables lava lakes, ores can generate in the stone around lava lakes, given the proper altitude. | All |
| fortress | None | Generates nether fortresses. | Nether |
| mansion | distance | Generates woodland mansions. | Dark Forest, Dark Forest Hills |
| oceanmonument | spacing separation |
Generates ocean monuments in the water. spacing determines the size of the grid, in chunks, on which monuments are generated (minimum is 1, default is 32). separation determines the minimum distance, in chunks, between monuments. (minimum is 1, default is 5). WARNING: spacing must be greater than separation, otherwise the game crashes. |
Deep Ocean, Deep Warm Ocean, Deep Lukewarm Ocean, Deep Cold Ocean, Deep Frozen Ocean |
| endcity | distance | Generates end cities. | End Highlands |
| pillager_outpost | None | Generates pillager outposts. | Plains Desert, Savanna, Taiga, Snowy Taiga, Snowy Tundra |
| ruined_portal | None | Generates ruined portals. | All |
| bastion_remnant | None | Generates bastion remnants. | Nether Wastes, Crimson Forest, Warped Forest, Soul Sand Valley |
Several criteria must be satisfied before some features can appear:
plains, desert, taiga, savanna, snowy_taiga, and snowy_tundra.For example, to have an 'End' superflat world with end spikes, the biome ID must be the_end, and the top surface block must be end stone. In this particular case 'Structures' does not need to be turned on in the world options.
Attempting to use an incorrectly formatted preset code causes the game to default to the Classic preset.
Consider the following preset code:
minecraft:mossy_cobblestone,250*minecraft:air,minecraft:obsidian,minecraft:snow;minecraft:plains
It consists of the following elements:
minecraft:mossy_cobblestone,250*minecraft:air,minecraft:obsidian,minecraft:snow — comma-separated list of block IDs.
minecraft:mossy_cobblestone — one layer of mossy cobblestone on layer -64.250*minecraft:air — 250 layers of air, from layer -63 to layer 186.minecraft:obsidian — one layer of obsidian, on layer 187.minecraft:snow — one layer of snow, on layer 188.minecraft:plains — biome ID, in this case Plains.In Java Edition, the level-type flag in server.properties must be set to minecraft\:flat for a server to generate as superflat.
The JSON object flag generator-settings in server.properties defines further customizations of the world, such as block layers, biome, and structures. The syntax is shown in the example below:
Example generation settings that recreate the "Classic Flat" preset:
generator-settings={"biome":"minecraft:plains","layers":[{"block":"minecraft:bedrock","height":1},{"block":"minecraft:dirt","height":2},{"block":"minecraft:grass_block","height":1}]} level-type=minecraft\:flat
In Bedrock Edition, setting the level-type field in server.properties to "FLAT" will generate a flat world.
