CustomWorldHeight

CustomWorldHeight is a plugin for Paper that allows you to modify the height of the Minecraft world. It provides an easy and efficient way to extend or limit the vertical dimensions of your world for creative builds, gameplay tweaks, or server optimization.

Github page: https://github.com/Lumine1909/CustomWorldHeight

Important

This plugin is similar to the vanilla datapack, so there will be some similar issues as the datapack one.

Once you set the height of a certain world, it will be VERY DANGEROUS to shirk the world height, all the data will lose.

Expand the height is relatively unharmful, but if you decrease the min-Y, new chunks will be different from already generated chunks.

Increasing the height will only cause the chunk's height map to be recalculated, and all the data will be properly preserved.

Features

• Customize the height of your Minecraft world.
• Seamless integration with Paper.
• Easy-to-configure settings for server administrators.

Installation

Follow these steps to install the plugin:

1. Download the latest release of CustomWorldHeight from the Releases page.
2. Place the downloaded .jar file into your server's plugins folder, start the server.
3. After plugin generated the config template it will automatically disable, please finish the config.
4. Restart your Minecraft server, and the configured world's height will be modified.

API Usage

repositories {
    mavenCentral()
}
dependencies {
    compileOnly("io.github.lumine1909:CustomWorldHeight-API:0.0.1")
}

public void modifyHeight() {
    /*
    All of these works only if the world is not loaded yet!
    This is not a permanent modification! If you want to set permanently,
    store the height data with your plugin and SET IT ON EACH STARTUP!
    */

    // Set the height of overworld
    WorldHeightService.get().registerWorld(
        Identifier.of("demo", "height1"), "world",
        new Height(1088, -64, 512, Height.CloudHeight.DEFAULT),
        BaseDimensionType.OVERWORLD
    );
    // Set the height of all worlds start with "test_"
    WorldHeightService.get().registerRegex(
        Identifier.of("demo", "height2"), "test_\\w+",
        new Height(1088, -64, 512, Height.CloudHeight.DEFAULT),
        BaseDimensionType.CUSTOM
    );
}

Configuration

# You can set to anything you want ([a-z0-9/._-]), will be used to generate Identifier (ResourceLocation)
example-namespace:

  # Set the height for certain world, you need set it to the world name you want to modify the height
  world: 'example-world-value'

  # Min Y position
  min-y: -64

  # Height (max Y position = min-y + height - 1)
  height: 1024

  # Height for Chorus Fruit teleport and etc., cannot be greater than height. See Minecraft wiki#DimensionType for details
  logical-height: 512

  # Height for the cloud (empty -> do not have cloud, default -> use default height)
  # This feature only works on 1.21.6+
  cloud-height: 'default'

  # For 'overworld', 'the_nether', 'the_end', 'overworld_cave', this will use built in data to generate before world is initializing
  dimension-type: 'overworld'

# You can set to anything you want ([a-z0-9/._-]), will be used to generate Identifier (ResourceLocation)
example-regex:

  # This plugin also support Regex matching
  regex: '^test_\w+'

  # Min Y position
  min-y: -64

  # Height (max Y position = min-y + height - 1)
  height: 1024

  # Height for Chorus Fruit teleport and etc., cannot be greater than height. See Minecraft wiki#DimensionType for details
  logical-height: 512

  # Height for the cloud (empty -> do not have cloud, default -> use default height)
  # This feature only works on 1.21.6+
  cloud-height: 256

  # This will let the plugin process registration data when world load
  dimension-type: 'custom'
