Solved Replace Blocks on Chunk Generation Without Making Custom Chunk Generator

Like the title says, is there any way to say like, replace all bedrock with stone when a chunk generates. I don't want to make a custom chunk generator because i want it to be exactly like in vanilla except for the bedrock part. I think it has to with block populators, but I don't know how to use those without making a custom chunk generator.

 

*Checks bukkit javaDocs* Ok, not an expert, but here's what I'm guessing. not giving all the info because I just looked in the javaDocs, and some other forums. no testing.

Code:

Block bedrock = chunk.getBlock(x, y, z);
                    if(bedrock.getType() == Material.BEDROCK){
                        bedrock.setType(Material.STONE);

 

But how do I get it while the chunk is generating?

 

OnEnable....? This will make it stone every time the plugin is enabled. right when the world is loading; also the first time it will do, So if you did that you should disable it after, it may cause a HUGE lag spike.

 

Use the "chunkLoadEvent" event.

 

ChunkLoadEvent would happen after onEnable, but yes; it is more accurate.

 

akabarblake He asked how he could get the chunk when it is generating

 

TGRHavoc When I do that, I get spammed with an extremely long stacktrace that is so big that I can't put it on pastebin because of the file size limit.

 

Do it the proper way and use a custom chunk generator. If you want it to be exactly like vanilla, then look through the source code and find the vanilla chunk generator.

 

coasterman10 I don't think there is a "vanilla chunk generator" written in craftbukkit code. All the vanilla code is in the nms packages.

 

Conarnar Can you take a screenshot of the error?

 

TGRHavoc It's extremely long, so I can't fit all of it into a screenshot. While I was looking through the logs I found this which may me the cause of it.

Conarnar What's the code for your class?

 

TGRHavoc

Code:java

package test;
 
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Test extends JavaPlugin implements Listener {
public void onEnable() {
getServer().getPluginManager().registerEvents(this, this);
}
 
@EventHandler(priority = EventPriority.MONITOR)
public void l(org.bukkit.event.world.ChunkLoadEvent q) {
for (int x = 0; x < 16; x++) {
for (int y = 0; y < 127; y++) {
for (int z = 0; z < 16; z++) {
Block block = q.getChunk().getBlock(x, y, z);
 
if (block.getType() == Material.BEDROCK) {
block.setType(Material.STONE);
}
}
}
}
}
}

 

Which are in the source.

What you're doing will cause lag, just saying.

 

I found this https://github.com/Bukkit/CraftBukk...aftbukkit/generator/NormalChunkGenerator.java
Which doesn't seem to work.

Code:java

public byte[] generate(org.bukkit.World world, Random random, int x, int z) {
        throw new UnsupportedOperationException("Not supported.");
    }

 

everything works, read code carefully and completely, not only lines you want.

your code is invalid, care to read javadocs about method before using it?

answer is "terrain control"

 

I didn't just read that line, I just posted a line I noticed to be forcibly throwing an exception.

Well of course it's invalid, why else would it not be working?

This isn't the plugin requests section where I lazily wait for someone to make or find a plugin for me.

 

Lazily download terrain control and lazily read its source code, or lazily wait someone to lazily spoonfeed you.

 

Then I will just lazily requests a plugin and lazily wait until someone makes it.

 

you will lazily get same responce again, nobody will waste time on plugin that already exists.

 

Yeah, you're right. TerrainControl is proving to be very useful (and fun).
