public class CityFeatureRegistration { public static final Holder<ConfiguredFeature<?, ?>> CITY_FEATURE = Feature.STRUCTURE.sidedBuilder(StructureFeatureConfiguration.CODEC) .parameter(StructureTemplateManager.PARAMETER_CODEC.fieldOf("structure")) .orElseThrow() .configure(StructureFeatureConfiguration::new) .buildHolder(CityFeature::generateCityFeature); // Building

public class District { private final Level level; private final BlockPosition pos; private final int index; // Building.java package com.example.minecraft.feature

// Add roof level.setBlock(new BlockPosition(pos.getX() + buildingSize / 2, pos.getY() + 1, pos.getZ() + buildingSize / 2), Blocks.STONE_SLAB.defaultBlockState(), 2); } } To register the feature, you can use the following code:

public Building(Level level, BlockPosition pos, int districtIndex, int buildingIndex) { this.level = level; this.pos = pos; this.districtIndex = districtIndex; this.buildingIndex = buildingIndex; }
