content.rs

1//! `.yblock` / `.yitem` content files — a mod's blocks and items: their
2//! properties, 3D model, block states and item form, in one JSON file each,
3//! edited in Yog-IDLE's 3D model editor — and `.yrecipe` files, one recipe
4//! each (crafting, shapeless, smelting), edited in its recipe editor. See
5//! Yog-IDLE's `docs/blocks-items.md` for the formats.
6//!
7//! `yog build` reads `content/**/*.yblock` and `content/**/*.yitem` and
8//!
9//! - writes Minecraft's JSON for them: block models, blockstates, item
10//!   models, 1.21.4+ item definitions (`assets/<ns>/items/`), block loot
11//!   tables, the `mineable/<tool>` and `needs_<level>_tool` block tags;
12//! - puts their names and tooltips into the lang files (a `@<Set>.<name>`
13//!   text of a `.yres` file under the key Minecraft looks up, a literal into
14//!   `en_us`);
15//! - builds the mod's textures (`.ytexture`, see `textures`);
16//! - generates `.yog-build/generated/yog-content.g.rs` — `Blocks`/`Items`
17//!   with an id constant and a `BlockDef`/`ItemDef` builder per entry and
18//!   a `register` function — pulled in by `yog_api::content!();`, which
19//!   also registers them (unless an entry says `"register": "manual"`) and
20//!   every recipe.
