Registrar

If you don't have the Modrinth maven in your repositories block, add it like so:

build.gradle:

maven {
    url("https://api.modrinth.com/maven")
    content {
        includeGroupAndSubgroups("maven.modrinth")
    }
}

or build.gradle.kts:

maven("https://api.modrinth.com/maven") {
    content {
        includeGroupAndSubgroups("maven.modrinth")
    }
}

Then, add this project to your dependencies.

If you're using deobfuscated Minecraft:

api("maven.modrinth:registrar:${project.registrar_version}") // or implementation
include("maven.modrinth:registrar:${project.registrar_version}")

If you're using obfuscated Minecraft:

modApi("maven.modrinth:registrar:${project.registrar_version}") // or modImplementation
include("maven.modrinth:registrar:${project.registrar_version}")

First, fork or download this repository and publish it to your mavenLocal.

Then, adding the following to your repositories block:

mavenLocal()

Then, add this project to your dependencies.

If you're using deobfuscated Minecraft:

api("survivalblock.atmosphere:registrar:${project.registrar_version}") // or implementation
include("survivalblock.atmosphere:registrar:${project.registrar_version}")

If you're using obfuscated Minecraft:

modApi("survivalblock.atmosphere:registrar:${project.registrar_version}") // or modImplementation
include("survivalblock.atmosphere:registrar:${project.registrar_version}")

AttachmentTypeRegistrant contains overloads to register with the builder or register with method parameters.

BlockEntityTypeRegistrant and DelayedBlockEntityTypeRegistrant implement IBlockEntityTypeRegistrant,
which can register BlockEntityType.Builder/FabricBlockEntityTypeBuilders depending on the version. It
can also take the BE's constructor (as a lambda) and a Block varargs to construct the BlockEntityType.

BlockRegistrant and DelayedBlockRegistrant implement IBlockRegistrant, which can register Blocks
based on a constructor and their BlockBehaviour$Properties. Note that BlockBehaviour$Properties#setId
is called for you.

In 26.2, createId methods are available to create BlockItemIds.

Due to BuiltinRegistries.GAME_RULE not existing before 1.21.11, GameRuleRegistrant's registry is
null in those versions. Registration in those versions is done via Fabric API's GameRuleRegistry, which
is not a real Registry.

DelayedGameRuleRegistrant does not exist before 1.21.11 for reasons described above.

Both GameRuleRegistrant and DelayedGameRuleRegistrant implement IGameRuleRegistrant, which contains
methods to register GameRules$Key/GameRules depending on the version. Overloads to register a boolean
rule exist, but due to the larger variation of ways to construct rules pre-1.21.11, these are not exhaustive.
It is recommended to make your own helpers as necessary.

IGameRuleRegistrant also contains minor multiversion utilities to obtain values from GameRules. These
can also be found in the actual registrants, which perform unboxing for some rules.
