YARRP

Has it ever bothered you that so much configuration of blocks, items, recipes, and now even enchantments is defined in untyped JSON files? Well then you should probably just use data generation which is much more battle tested and even used by Mojang for the Vanilla data. But, if you also want to be able to adjust the data dynamically or want some things to be configurable, then this might just be the thing for you. YARRP is inspired by ARRP and BRRP but written from the ground up with an easy to use Kotlin API. It allows you to create resource packs (i.e. both data packs and asset packs) at runtime, so you don't need to have JSON files ready for all possible options.

Usage

To add YARRP as a dependency, add the following to your `build.gradle.kts`:

```kotlin repositories { // you can use either one maven("https://jitpack.io") maven("https://api.modrinth.com/maven") }

dependencies { // replace the versions and loader as needed. the loader is one of `fabric` or `neoforge` modImplementation("com.github.RubixDev.YARRP:yarrp-mc1.21.1-fabric:v0.2.0") // when using jitpack modImplementation("maven.modrinth:yarrp:0.2.0+1.21.1-fabric") // when using modrinth maven } ```

Don't forget to also list YARRP as a dependency in your `fabric.mod.json` and `neoforge.mods.toml` files.

You can then use YARRP by creating a pack and adding it to one of the register callbacks. Here's an example:

```kotlin object MyModResources { // call this in your mod initializer fun register() { YarrpCallbacks.register(PackPosition.AFTER_VANILLA, ResourceType.SERVER_DATA) { add(PACK) } }

@JvmField val PACK = RuntimeResourcePack( RuntimeResourcePack.createInfo( Identifier.of("modid", "my_runtime_pack"), Text.of("Pack Title"), "pack version", // should probably be set to the version of your mod ), RuntimeResourcePack.createMetadata(Text.of("pack description")), )

val MY_ENCHANTMENT: RegistryKey<Enchantment> = PACK.addEnchantment( Identifier.of("modid", "my_enchantment"), Enchantment.definition( // this dummy type can be used to create a RegistryEntryList from a given TagKey // but should only be used for adding resources to a runtime pack DummyHolderSet(ItemTags.LEG_ARMOR_ENCHANTABLE), 5, 3, Enchantment.leveledCost(5, 8), Enchantment.leveledCost(55, 8), 2, AttributeModifierSlot.LEGS, ), )

init { if (MyModSettings.myEnchantmentIsTreasure) { PACK.addTag(EnchantmentTags.TREASURE) { add(MY_ENCHANTMENT) } } else { PACK.addTag(EnchantmentTags.NON_TREASURE) { add(MY_ENCHANTMENT) } }

if (MyModSettings.enableRecipe) { PACK.addRecipeAndAdvancement( Identifier.of("modid", "my_recipe"), ShapedRecipeJsonBuilder.create(RecipeCategory.MISC, Items.DIAMOND, 64) .criterion("tick", TickCriterion.Conditions.createTick()) .pattern("//") .pattern("//") .input('/', Items.STICK), ) } } } ```
