Estecka / mc-Variants-CIT

A specialized CIT logic for enchanted books

Variants-CIT

A CIT logic for MC 1.21, optimized around items with standardized variants.

This mod is not a plug-and-play replacement for Optifine/CIT-resewn; it uses its own resource format. Changes to older packs are required for them to work.

The mod contains built-in logic for handling Axolotl Buckets, Enchantments, Music Discs, Goat Horns, and Potions. There are also more generic modules that can identify a variant from the custom_data or custom_name component of an item. Other mods can easily create custom logic for their own items.

If Mojang ever makes these items data-driven, you can expect Banner Patterns, Trim Templates, and Pottery Sherds to become supported in the future.

Difference with Optifine/CIT-Resewn

The base concept for this mod was born out of a need for optimization, at a time when CIT-resewn was still an up-to-date option. This comes at the cost of some flexibility; while being multi-purpose, it may not be as all-purpose as optifine.

This mod excels in scenarios where a single item type has a large amount of variants, which can all be derived from a single piece of data. Instead of defining a condition for every single CIT, you define a single rule that governs all CITs in a collection (so-called modules).

Resource Pack Format

This is an overview, see the wiki for a complete guide.

The format revolves around item variants (reduced to namespaced identifiers) being automatically associated to item models with matching names, stored in a directory of your choosing.

Resource packs must start by providing a module configuration, that defines what item is affected, how to figure out its variant, and where their models are located.

For example, here's a module that would reproduce the behaviour of the previous version of the mod, Enchants-CIT :
/assets/minecraft/variant-cits/item/enchanted_book.json

{
	"type": "stored_enchantment",
	"items": ["enchanted_book"],
	"modelPrefix": "item/enchanted_book/",
	"special": {
		"multi": "enchants-cit:item/multi_enchanted_book"
	}
}

Here, the enchantment minecraft:unbreaking will be associated with the model stored at /assets/minecraft/models/item/enchanted_book/unbreaking.json

Some module types may define additional models to use in special cases, or take addional parameters.
