Module content 

.yblock / .yitem content files — a mod’s blocks and items: their properties, 3D model, block states and item form, in one JSON file each, edited in Yog-IDLE’s 3D model editor. See Yog-IDLE’s docs/blocks-items.md for the format.

yog build reads content/**/*.yblock and content/**/*.yitem and

• writes Minecraft’s JSON for them: block models, blockstates, item models, 1.21.4+ item definitions (assets/<ns>/items/), block loot tables, the mineable/<tool> and needs_<level>_tool block tags;
• puts their names and tooltips into the lang files (a @<Set>.<name> text of a .yres file under the key Minecraft looks up, a literal into en_us);
• bundles textures given as paths inside resources/;
• generates .yog-build/generated/yog-content.g.rs — Blocks/Items with an id constant and a BlockDef/ItemDef builder per entry and a register function — pulled in by yog_api::content!();, which also registers them (unless an entry says "register": "manual").

Modules

json

A small JSON reader that remembers the line of every value, so .yblock and .yitem errors point at file:line (serde_json only knows where a syntax error is).

Structs

Compiled

Everything yog build makes of a mod’s content files.

OutputSet

Outputs in order, keyed by path: OutputSet::put replaces a path’s output (moving it to the end) without rescanning the list.

Template

A model template — "parent": "cube_all" — and the texture slots it takes.

Enums

Kind

What a content file defines.

Constants

CONTENT_DIR

Where content files live, under the mod root.

DIRECTIONS

DISPLAY_SLOTS

GENERATED_FILE

The generated Rust code, under the mod root.

RENDER_LAYERS

SOUNDS

The sound groups the loaders map (BlockDef::sound).

TEMPLATES

TOOLS

TOOL_LEVELS

Functions

compile

Compiles the mod’s content files (see the module docs). Any error fails the whole thing, listing every problem.

find

Every content/**/*.yblock|*.yitem of the mod at root, sorted.

import_command

yog import ... (args after import).

merge_outputs

Adds the content’s outputs to outputs (the .yres ones, say): lang entries and tags merged into what’s there (or into the mod’s own files), the rest appended.

template

valid_id

ns:path (or path, in minecraft) as a valid resource id.

valid_namespace

[a-z0-9_.-]+ — a Minecraft namespace.

valid_path

[a-z0-9_./-]+ — a Minecraft resource path.

write_source

Writes compiled.source to GENERATED_FILE (only when it changed); deletes it when the mod has no content files.

Type Aliases

Output

A generated file: path inside the .yog and its bytes.
