yog_registry/
lib.rs

1//! Content registration — declare custom items and blocks from Rust.
2//!
3//! Definitions are collected at registration time and handed to the host, which
4//! registers real `Item`/`Block` objects before the game's registries freeze,
5//! puts them in per-namespace creative tabs, and applies their properties.
6//! (Textures, models and recipes are assets/data shipped in the `.yog` and
7//! served to the game.)
8//!
9//! ```
10//! # use yog_registry::{ItemDef, BlockDef, FoodDef};
11//! ItemDef::new("mymod:ruby").name("Ruby").tooltip("A shiny gem.").max_stack(16);
12//! ItemDef::new("mymod:pie").food(FoodDef::new(4, 0.3));
13//! BlockDef::new("mymod:lamp").light_level(15).sound("stone");
14//! ```
