KubeJS Utility & QoL World Gen

World generation integration for KubeJS. Allows for the addition of configured features, placed features, and biome modifiers using KubeJS's ServerEvents.registry

Supports:

  • All vanilla configured feature types (+ a WorldJS custom type)
  • All vanilla placement modifier types (+ placed features)
  • All NeoForge biome modifiers

Additionally, support for other placement modifier types can be added with the provided PlacedFeatureModifierEvent

Example

ServerEvents.registry('worldgen/configured_feature', event => {
    event.create('delta_feature', 'delta_feature')
        .size([11, 15])
        .rimSize([1, 3])
        .rim('minecraft:calcite')
        .contents('minecraft:lava')
        .withPlacement('minecraft:delta', p => { // Overwrite the vanilla placed feature
            p.modifiers(modifiers => {
                let { minecraft } = modifiers
                minecraft
                    .countOnEveryLayer(40)
                    .biome()
            })
        })
})
