When creating a new world or modifying one, you have access to a menu with some options.
On this page we will explain what they are and what they do.
- World name: This is where you have the option to name your world. If you do not want a custom name, a random one will be chosen. See New World Names page for default world names. The world name can be modified later.
- Seed: This is an alphanumerical character chain that is used by the world generation algorithm to generate terrain. Two worlds with the same seed will be generated identitally. Leave blank for a random seed. You cannot change this setting later.
- Game mode: Here you can choose the game mode. It can be changed anytime, except for Cruel gamemode (you can only chose Cruel at creation of the world, and it can't be modified afterwards). The possible gamemodes are Challenging Gamemode, Cruel Gamemode, Creative Gamemode, Harmless Gamemode , and Adventure Gamemode. Adventure Gamemode cannot be chosen at world creation. A previously created world may be changed to adventure mode to create a quest or adventure type world.
- There is a button on the bottom of the screen that says Setup Player that sends you to the Player Options screen.
If you have chosen Creative as a gamemode, you can change many world options.
- Customize Paint Colors: It has a selection of all the 16 colors available in the game. You can change every color on the game by adjusting the RGB. Also you can rename it.
- Supernatural creatures: In ENABLED hostile creatures or semi-hostile creatures will spawn in the world. In DISABLED no hostile or semi-hostile creatures will summon.
- Environment behavior: In LIVING mode the world is a living place full of animals. Plants and grass grow, blocks made of loose material collapse and detached leaves decay. In STATIC mode the world has no animals. Plants growth, block collapsing and plant decay are disabled. Useful if you want to shape your world the way you want it.
- Time of Day: Choose whether you want time to flow normally or if you want the stars, sun and moon to stay stationary at a particular moment of time (DAY, NIGHT, SUNRISE, or SUNSET. If you are building large, it can be useful to set the time to sunrise so you always know which way the ocean is.
- Weather effects: ENABLED (The world will experience periodical occurences of rain and snow that will accumulate on the ground. Lightning will strike tall objects and set them on fire.) or DISABLED (There will be no precipitation or lightning in the world.)
- Adventure Respawn: ALLOWED (The player will be able to respawn at his last spawn or sleeping place when he dies (good for long adventures with checkpoints)) or NOT ALLOWED (The player will not be able to respawn, but will have to restart the adventure and start from scratch when he dies (good for small adventures with no checkpoints))
- Disable adventure survival mechanics, if enabled will make your character stay at a constant hunger, stamina and will not be affected by sleep loss. When disabled, adventure mode you will need to eat, sleep and stop and catch your breath when moving.
- This is used when creating a world that will later be saved in ADVENTURE mode.
- Terrain Mode: In Continent mode the environment is made to look like the real world, full of forests, plains, deserts, glaciers, lakes. mountains, hills, caves and so on. In Flat mode the terrain is completely flat, giving you the total freedom of creation. You can also change terrain level and type of block that fills it. In Island mode the enviroment is an island generated with water around it.
- Sea level, it is only increasable and at the highest amount the world will be made up of small islands.
- You can change the global temperature and humidity of the world in either flat or normal terrain modes. They range from -16 to +16 and will determine the average world values.
- In continent mode, the temperature and humidity will still vary according to the local biome. A lower value of temp will create mostly cold biomes covered in snow or ice. A higher temp will create warmer biomes with little or no snow. A higher humidity will create more wet areas and jungle or marsh type biomes. A lower humidity will create more desert and wasteland biomes with very little vegetation. The temp and humidity can be adjusted to create the type of world environment you wish.
- In flat mode, the temperature and humidity will be the same everywhere. For instance, a temp value of -10 or less will have thermometer readings of '0' everywhere in the world
- Flat mode options:
- Flat Terrain Level: Adjust the level of terrain above bedrock, only applicable in flat terrain mode. The lower you put it, the more space will be available above ground. The higher you put it, the more space will be available underground. (At the maximum of 104, you will have 22 blocks above the ground level in which to build.)
- Flat terrain block: You can choose which type of block you want the world to be made of. The choices are: Grass, Dirt, Sand, Granite, Basalt, Limestone, Sandstone, Cobblestone, Stone Bricks, Brick Wall, Solid Iron Block, Solid Copper Block, Glass, Ice, Marble, Solid Diamond Block, Malachite Block or Bedrock. (Yes, you can have a world made of solid diamond blocks!) The bedrock bottom of the world will always still be bedrock.
- Magma Ocean: Turn the ocean into a sea of magma. This is usually not a good idea.
- Although Solid Diamond Block is flammable, you can choose that as your terrain block with a magma ocean. However it does not seem to catch fire. It does not seem to make an ice world melt, either.
- If you set a living environment, birds will land on it and catch fire plus, there will be no fish of course.
- The magma ocean option was added in 1.23.
- Island mode options:
- Island Size east/west: The island can adjust the size by east/west from 30.
- Island Size north/south: The island can adjust the size by north/south from 30.
