Hello, I want to create a mod where player create a village to gain ressources and more functions. (mod version is 1.18.1) To start, i want player to right click on a block and spawn the structure like a miner house or the chef house. I use the function NBT to see what is inside the CompoundTag and understand it. The problem is that I can get data from the Compound only with the compound.get() even if I get Type of the tag, i can't get ListTag even for blocks in the nbt file. All method to get data from CompoundTag or Tag doesn't work. Could someone explain or link a solution, a path to understand ? This is the Structure class that I have created : package com.tios.villageum.world.structure; import com.tios.villageum.Villageum; import net.minecraft.core.BlockPos; import net.minecraft.nbt.*; import net.minecraft.network.chat.NbtComponent; import net.minecraft.resources.ResourceLocation; import net.minecraft.server.packs.resources.Resource; import net.minecraft.server.packs.resources.ResourceManager; import net.minecraft.world.level.Level; import net.minecraft.world.level.block.Block; import net.minecraft.world.level.block.state.BlockState; import net.minecraft.world.level.levelgen.structure.templatesystem.StructureManager; import net.minecraft.world.level.levelgen.structure.templatesystem.StructureTemplate; import java.io.*; import java.util.List; import java.util.zip.GZIPInputStream; public class Structure { public int length; // X public int height; // Y public int width; // Z protected String fileName; protected InputStream fileStream; private BlockState[][][] blocks; private int[][][] blockData; private CompoundTag[] entities; private CompoundTag[] tileEntities; public Structure(String filename){ this.fileName = filename; this.fileStream = Structure.class.getResourceAsStream("/assets/"+Villageum.MOD_ID+"/structs/" + filename + ".nbt"); } public void createStructure(Level level, BlockPos pos){ } public boolean emptyInSizedSpace(Level level, BlockPos pos) { return level.getChunkAt(pos).isEmpty(); } public void readFromFile() { CompoundTag nbtTagCompound = null; DataInputStream dataInputStream; try { dataInputStream = new DataInputStream(new GZIPInputStream(this.fileStream)); nbtTagCompound = NbtIo.read(dataInputStream); dataInputStream.close(); } catch (Exception e) { System.err.println("Villageum Mod: Error loading structure '" + this.fileName + "'"); return; } var keys = nbtTagCompound.getAllKeys(); var size1 = nbtTagCompound.get("size").getAsString().replace("[","").replace("]","").split(","); // In schematics, length is z and width is x. Here it is reversed. this.length = Integer.parseInt(size1[0]); this.height = Integer.parseInt(size1[1]); this.width = Integer.parseInt(size1[2]); int size = this.length * this.width * this.height; blocks = new BlockState[this.height][this.width][this.length]; blockData = new int[this.height][this.width][this.length]; NBT(nbtTagCompound, "blocks"); var tag = nbtTagCompound.get("blocks"); byte[] blockIdsByte = nbtTagCompound.getByteArray("blocks"); byte[] blockDataByte = nbtTagCompound.getByteArray("palette"); int x = 1, y = 1, z = 1; for (int i = 0; i < blockIdsByte.length; i++) { int blockId = (short) (blockIdsByte[i] & 0xFF); blocks[y - 1][z - 1][x - 1] = Block.stateById(blockId); blockData[y - 1][z - 1][x - 1] = blockDataByte[i]; x++; if (x > this.length) { x = 1; z++; } if (z > this.width) { z = 1; y++; } } ListTag entityList = nbtTagCompound.getList("Entities", 10); entities = new CompoundTag[entityList.size()]; for (int i = 0; i < entityList.size(); i++) entities[i] = entityList.getCompound(i); /* ListTag tileEntityList = nbtTagCompound.getList("TileEntities", 10); tileEntities = new CompoundTag[tileEntityList.size()]; for (int i = 0; i < tileEntityList.size(); i++) tileEntities[i] = tileEntityList.getCompound(i);*/ } private void NBT(CompoundTag compoundTag,String key){ var id = compoundTag.getId(); var keys = compoundTag.getAllKeys(); var contain = compoundTag.contains(key); var tag = compoundTag.get(key); var type = tag.getType(); var astring =tag.getAsString(); } }
