Nether API

A library mod for adding End and Nether biomes or structures, and for creating new biome ambience!

Also unifies different older mods' End and Nether biome generators under one system, fixes respawn dimension logic and other bugs, and offers new settings for the End and Nether.

If you're a modpack developer wanting to add Nether API to a modpack distributed outside of CurseForge or Modrinth, use File Director to avoid reuploading Nether API's files.

API Features:

Ability to add custom biome ambience!

• This is applicable to any biome, not just End or Nether biomes.
• Can have passive ambient sounds (can also be set with 0).
• Can have a custom darkness ambient sound (can also be set with 0).
• Can spawn passive particles (can also be set with 0).
• Can have a custom lava color (idea provided by Mellohi).

Ability to add custom End and Nether biomes!

• Can have a custom biome generation weight (can be set with 0).
• Can have a custom fog color (can also be set with 0).
• Can have a custom music type.
• Can have a custom surface builder, and a custom chunk populator.
• Can have custom cave carving conditions.
• Can have custom Chorus Plant, End City, and Small End Island generation conditions (End biomes only).
• Can have multiple weighted sub-biomes and edge-biomes.

Ability to add custom End and Nether structures!

• Can generate between chunks (like Nether Fortresses).
• Can have custom entity spawning properties (like Nether Fortresses).
• Can have custom generation conditions.
• All registered structures automatically work with the /locate command.
• All registered structures automatically check for other structures when generating, so they won't intersect.

New EnumPlantTypes!

• These are applied automatically by Nether API to various modded End and Nether plants and soil blocks, to let them respect other mods' "End Stone"-like or "Netherrack"-like soil blocks. This allows for new inter-compatibility between any plants and soils from different mods that use them!
• 0: This PlantType is for any plants that can be planted on "End Stone"-like blocks. At runtime this is automatically applied to Vanilla's Chorus Plants.
• 0: This PlantType is for any plants that can be planted on both "Netherrack"-like blocks and "Soul Sand"-like blocks.
• 0: This PlantType is for any plants that can be planted on "Netherrack"-like blocks.
• 0: This PlantType is for any plants that can be planted on "Soul Sand"-like blocks. This field just set to Forge's EnumPlantType.Nether, since they serve the same purpose.

Mod Features:

Features:

• Allows end biome mods to work together by unifying end biome generation code!
• Allows nether biome mods to work together by unifying nether biome generation code!
• Allows users to define a default "player spawn dimension" through new config settings!
• Automatically enables Forge's cascading world gen fix during End & Nether generation!
• Caves can now generate in the End's outer islands!
• Nether caves can now carve through biome top/filler blocks and soul sand (instead of only netherrack)!
• New config setting to disable the first Ender Dragon spawn. When this setting is active: an End Gateway will generate, the Ender Dragon can still be summoned using End Crystals, and the dragon egg still appears after the Ender Dragon's first death.
• The Nether can now be 256 blocks tall!
• This feature is disabled by default.
• This feature should only be enabled for new worlds (or old worlds if you reset the Nether first).
• For many mods that generate their own nether features, you'll have to adjust their configs to account for the new height. Currently all mods
