I am replacing blocks in chunks. Every time a chunk is loaded, I replace generating blocks with a random other one. So here is my code

package de.belinked.chunkrandomizer;

import java.util.Arrays;
import java.util.List;
import java.util.concurrent.ThreadLocalRandom;

import org.bukkit.Bukkit;
import org.bukkit.Chunk;
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.world.ChunkLoadEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class ChunkRandomizer extends JavaPlugin implements Listener {
    
    public List<Material> blocks = Arrays.asList(
            Material.ACACIA_LEAVES,
            Material.ACACIA_LOG,

            // I'll leave this out, just every full, solid block

            Material.YELLOW_STAINED_GLASS,
            Material.YELLOW_TERRACOTTA,
            Material.YELLOW_WOOL
    );
    
    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this, this);
        Bukkit.broadcastMessage(this.prefix   "Der Chunk-Randomizer wurde erfolgreich geladen");
    }
    
    @Override
    public void onDisable() {
        
    }
    
    public Material getRandomMaterial(List l) {
        int rnd = ThreadLocalRandom.current().nextInt(l.size());
        Material m = (Material) l.get(rnd);
        return m;
    }
    
    @EventHandler
    public void onChunkLoad(ChunkLoadEvent e) {
        if(e.isNewChunk()) {
            Chunk chunk = e.getChunk();
            Block b;
            Material m = getRandomMaterial(this.blocks);
            for(int y = -64; y <= 320; y  ) {
                for(int x = 0; x < 16; x  ) {
                    for(int z = 0; z < 16; z  ) {
                        b = chunk.getBlock(x, y, z);
                        if(!b.getType().isAir() 
                                && b.getType() != Material.BEDROCK 
                                && b.getType() != Material.WATER 
                                && b.getType() != Material.LAVA
                                && b.getType() != Material.END_PORTAL_FRAME
                                && b.getType() != Material.END_PORTAL) {
                            b.setType(m);
                        }
                    }
                }
            }
        }
    }
}

but when I join the server and load a few chunks then I get this log:

Can anyone help me fix this?

Edit: now I get kicked and for a while nothing happens, then I get this log which is even to long for the console: https://pastebin.com/8eZ4Ja4m

In the error, line 77, it says :

Cannot get data for not block BRICK

I think the problem comes from your list blocks. Somewhere in it, there must be a Material.BRICK, but in fact, I think the material should be Material.BRICKS, Bricks being the whole block, and Brick being the cooked clay item to make the Bricks block.

CodePudding user response：

You should check that you well have api-version: 1.13 in your plugin.yml.

It's because some mapping names changes, and they are not well detected by spigot without this option.
