With Spigot 1.18, I've noticed strange behavior during the custom chunk generation.
When a new ChunkData is generated, the entire chunk is jungle biome but, from 0 to 15 in height, it is plains biome.
I've used the following code to test it.
package it.gamerover.generator; import org.bukkit.Bukkit; import org.bukkit.Material; import org.bukkit.World; import org.bukkit.block.Biome; import org.bukkit.block.data.BlockData; import org.bukkit.generator.ChunkGenerator; import org.bukkit.generator.WorldInfo; import org.jetbrains.annotations.NotNull; import java.util.Random; @SuppressWarnings("deprecation") public class TestChunkGenerator extends ChunkGenerator { private static final BlockData DIRT = Bukkit.createBlockData(Material.DIRT); private static final BlockData GRASS = Bukkit.createBlockData(Material.GRASS_BLOCK); @NotNull @Override public ChunkData generateChunkData(@NotNull World world, @NotNull Random random, int chunkX, int chunkZ, @NotNull ChunkGenerator.BiomeGrid biomeGrid) { ChunkData chunkData = createChunkData(world); for (int x = 0 ; x < 16 ; x++) { for (int z = 0 ; z < 16 ; z++) { biomeGrid.setBiome(x, z, Biome.JUNGLE); for (int y = 0 ; y < 3 ; y++) { chunkData.setBlock(x, y, z, DIRT); } chunkData.setBlock(x, 3, z, GRASS); } } return chunkData; } }
This issue is repeated for each generated biome of the world.
I have also attached some screenshots taken with the Vanilla Minecraft 1.18 client to visually explain the issue.
