Minecraft World Generation

Use this skill for biome, dimension, feature, or structure data and their registration. Use minecraft-datapack for non-worldgen data and minecraft-modding for non-worldgen gameplay code.

Routing Boundaries

  • Use when: the task changes worldgen data, registration, or injection.
  • Do not use when: the task is non-worldgen datapack work (minecraft-datapack).
  • Do not use when: the task is non-worldgen mod systems (minecraft-modding).

BiomeModification API (Fabric)Adding features/spawns to existing biomesFabric

Worldgen registries are datapack registries: their files load at world load and their registry path determines the data path. Read the NeoForge registry guide before choosing a mod-specific registry path.

Version boundary

Treat Minecraft 26.x as the current lane for new work. Use Java 25 and start each JSON schema from the exact target's vanilla data or generated output. Do not copy a 1.21 shape into a 26.x pack merely because it parses as JSON.

Preserve an established 1.21.x project on Java 21 and its matching schema unless the task explicitly includes an upgrade. Do not mix compatibility lanes.

The 26.1 migration primer removes minecraft:random_patch and minecraft:no_bonemeal_flower. It replaces the random-patch pattern with a separate minecraft:simple_block configured feature and placements for count, random offset, and block-predicate filtering. Inspect the relevant primer section before migrating code or data.

Read legacy 1.21 JSON patterns only when the project targets that compatibility lane. Those examples are not release artifacts for 26.x.

Build and review the graph from its leaves upward:

  1. Define a configured feature, then its placed feature.
  2. Reference placed features from a biome or biome modifier at the intended decoration step.
  3. Define a structure, then its structure set; a jigsaw structure also needs a template pool, processor list, and structure template.
  4. Define a dimension type and noise settings before a dimension that references them.

Use fully qualified identifiers across namespaces. An external minecraft: or dependency reference is valid when that dependency supplies the registry entry; do not create a local copy merely to satisfy static checking. If the same pack contains that external namespace and registry directory, treat it as local and verify the target exists.

Biomes and dimensions

For 26.x biome and dimension data, use the exact target's vanilla data or datagen output as the schema source. The older effects and dimension-type fields do not model newer environment behavior. The 11 decoration steps still organize placed features; choose the semantically appropriate step and keep ore placement in underground_ores.

The version-labeled 1.21.5 biome and dimension examples are in legacy 1.21 JSON patterns.

26.x feature pattern

For the 26.1 replacement for a simple random patch, the migration primer shows a simple_block configured feature and a placed feature with count, random offset, and a block-predicate filter. Adapt the exact values and block state to the target release's generated data.

At data/<namespace>/worldgen/configured_feature/my_plant.json:

{
  "type": "minecraft:simple_block",
  "config": {
    "to_place": {
      "type": "minecraft:simple_state_provider",
      "state": { "Name": "minecraft:sweet_berry_bush", "Properties": { "age": "3" } }
    }
  }
}

At data/<namespace>/worldgen/placed_feature/my_plant.json:

{
  "feature": "<namespace>:my_plant",
  "placement": [
    { "type": "minecraft:count", "count": 96 },
    {
      "type": "minecraft:random_offset",
      "xz_spread": { "type": "minecraft:trapezoid", "min": -7, "max": 7, "plateau": 0 },
      "y_spread": { "type": "minecraft:trapezoid", "min": -3, "max": 3, "plateau": 0 }
    },
    {
      "type": "minecraft:block_predicate_filter",
      "predicate": {
        "type": "minecraft:all_of",
        "predicates": [
          { "type": "minecraft:matching_block_tag", "tag": "minecraft:air" },
          { "type": "minecraft:matching_blocks", "blocks": "minecraft:grass_block", "offset": [0, -1, 0] }
        ]
      }
    }
  ]
}

NeoForge biome modifiers

Biome modifiers load from data/<modid>/neoforge/biome_modifier/<path>.json. They can target a biome id or tag and add or remove placed features, among other changes. The current Biome Modifiers guide documents their schemas, decoration steps, and datagen.

For neoforge:add_features, features accepts a placed-feature id, list, or tag. Vanilla placed features may be referenced in biome JSON or added with a modifier, but NeoForge cautions against doing both because feature-order cycles can crash world loading. Prefer a copy under the mod namespace when an injected vanilla feature would create that risk.

When targeting a biome from an optional dependency, put the target in a biome tag entry with required: false, then use that tag in the modifier. This lets the pack load when the dependency is absent.

Structures and dimensions

For any current release, derive structure, template-pool, dimension, and dimension-type JSON from that release's vanilla data or datagen output. Confirm the reference graph before launching a test world:

  • structure_set references structure.
  • Jigsaw start_pool references template_pool; each single-pool element references its structure template and processor list.
  • dimension.type references dimension_type; a noise generator's string settings references worldgen/noise_settings.

For Fabric registration or mod datagen, use the exact loader and API version's documentation rather than copying 1.21 code into a 26.x project.

The detailed 1.21 structure and dimension examples are in legacy 1.21 JSON patterns.

Development Workflow

  1. Create or edit worldgen JSON files in data/<namespace>/worldgen/ (or equivalent mod resources path).
  2. Run the bundled validator to catch JSON and cross-reference errors before loading: 
    ./scripts/validate-worldgen-json.sh --root /path/to/datapack-or-mod-resources
# Strict mode treats warnings as failures:
./scripts/validate-worldgen-json.sh --root /path/to/datapack-or-mod-resources --strict
  3. Fix any reported errors and re-validate until clean. The validator checks:
    • JSON validity for worldgen/** and neoforge/biome_modifier/**
    • Cross-reference integrity for placed_feature -> configured_feature
    • Cross-reference integrity for structure_set -> structure and biome/biome_modifier feature targets
    • Cross-reference integrity for jigsaw structure -> start_pool and template_pool -> structure template / processor_list
  4. Compare biome and dimension-type JSON against the exact target's vanilla registry shape before in-game testing. The helper does not run Mojang codecs: valid JSON and local references do not prove that fields such as carvers, effects, or dimension settings match that release's schema.
  5. In-game biome and structure testing: 
    /locate structure <namespace>:my_structure
/locate biome <namespace>:my_biome
/place feature <namespace>:my_ore
    place feature takes a configured-feature ID, not its placed-feature wrapper. See Mojang's place command reference in the 1.19 release notes.
  6. For dimension testing, use /execute in (dimension must exist at world load, not added via /reload): 
    execute in <namespace>:my_dimension run tp @s 0 100 0
  7. Check latest.log for worldgen errors (missing biome references, malformed noise settings).
  8. Note: /reload refreshes datapack JSON but does not re-generate already-generated chunks. Test new worldgen in a fresh world or newly generated chunks. For existing test worlds, use a disposable copy and a purpose-built chunk reset/regeneration workflow; /fill only replaces blocks and is not a substitute for world generation.

# Minecraft World Generation

Use this skill for biome, dimension, feature, or structure data and their
registration. Use `minecraft-datapack` for non-worldgen data and
`minecraft-modding` for non-worldgen gameplay code.

## Routing Boundaries

- `Use when`: the task changes worldgen data, registration, or injection.
- `Do not use when`: the task is non-worldgen datapack work (`minecraft-datapack`).
- `Do not use when`: the task is non-worldgen mod systems (`minecraft-modding`).

## Choose the delivery path

| **Biome Modifier (NeoForge)** | Adding features/spawns to existing biomes | NeoForge |
| **BiomeModification API (Fabric)** | Adding features/spawns to existing biomes | Fabric |

Worldgen registries are datapack registries: their files load at world load and

3. Fix any reported errors and re-validate until clean. The validator checks:

   - Cross-reference integrity for `placed_feature -> configured_feature`
   - Cross-reference integrity for `structure_set -> structure` and biome/biome_modifier feature targets

   `place feature` takes a configured-feature ID, not its placed-feature wrapper.
   See Mojang's [place command reference in the 1.19 release notes](https://www.minecraft.net/en-us/article/the-wild-update-out-today-java).
6. For dimension testing, use `/execute in` (dimension must exist at world load, not added via `/reload`):
   ```mcfunction
   execute in <namespace>:my_dimension run tp @s 0 100 0
