Quick start

Get Lithostitched integrated into your Minecraft mod in minutes

1

Add the dependency

Add Lithostitched to your mod’s dependencies. For Fabric, add to your build.gradle:
gradle
repositories {
    maven { url "https://api.modrinth.com/maven" }
}

dependencies {
    modImplementation "maven.modrinth:lithostitched:1.5.8+beta1"
}
For NeoForge, use the same repository and adjust the dependency configuration:
gradle
implementation fg.deobf("maven.modrinth:lithostitched:1.5.8+beta1")
2

Create a worldgen modifier

Create a JSON file in your mod’s data directory at data/yourmod/lithostitched/worldgen_modifier/example.json:
{
  "type": "lithostitched:add_template_pool_elements",
  "priority": 1000,
  "target_pool": "minecraft:village/plains/houses",
  "elements": [
    {
      "element": {
        "location": "yourmod:village/plains/custom_house",
        "processors": "minecraft:empty",
        "projection": "rigid"
      },
      "weight": 5
    }
  ]
}
This modifier adds a custom house to Plains village structure pools.

Test in-game

Launch Minecraft with your mod and create a new world. Your worldgen modifications will automatically be applied. Use /locate structure minecraft:village_plains to find a village and see your changes.
Worldgen modifiers are loaded during world initialization. Changes won’t affect existing chunks—create a new world or explore ungenerated terrain.
