Referring to a custom Generator in code

I'm trying to create a new world based that uses the VoidGenerator plugin. However I'm unsure if I can refer to it using a string like I did in the code right under this text or do I need to implement the generator into my code entirely in order to use it? (Wich I'm unsure how to do)

Code:

        WorldCreator c = new WorldCreator(worldname);
        c.generator("VoidGenerator");
        World world = c.createWorld();    

If it helps I can say that I want every world to be genned with VoidGenerator, I previously thought I could use bukkit.yml 'Generator:' for this, however that doesn't work either. Could it be that I have placed it in the wrong spot, or is just that it doesn't work on a global level?

Bukkit.yml:

Greets,
Jeroen V.

 

Afaik you would have to use the other plugin (the one in which the generator is defined) and just create an instance of their generator

 

There is no way to let bukkit.yml use the generator for all worlds? For example, how does multiverse do this? I heard it can use external generators.

 

Code:java

@Override
public ChunkGenerator getChunkGenerator(String generator, String generatorID, String worldName) {
    if (generator == null) {
        return null;
    }
 
    Plugin myPlugin = this.plugin.getServer().getPluginManager().getPlugin(generator);
    if (myPlugin == null) {
        return null;
    } else {
        return myPlugin.getDefaultWorldGenerator(worldName, generatorID);
    }
}

That is what MultiVerse does (long live opensource code). String generator is just the plugin name, and they call getDefaultWorldGenerator(), which should be defined in the main class of the generator plugin

 

I've going through some codes and googling some stuff, now this is where I'm at:

Code:

        WorldCreator c = new WorldCreator(worldname);
        c.environment();
        Plugin myPlugin = this.plugin.getServer().getPluginManager().getPlugin("NullTerrain");
        c.generator(myPlugin.getDefaultWorldGenerator(worldname,null));
        World world = c.createWorld();    

However, for some reason it still wont use NullTerrain as generator for the world.

Alright, after some more trying I decided to just copy the class over (because it's so small and it's opensource). But how do I actually use this as a c.generator()?


Here's the class:

Code:

public class NullGenerator extends ChunkGenerator{
 
 
    public byte[] generate(World world, Random random, int cx, int cz)
    {
    return new byte[32768];
    }
 
    @Override
    public Location getFixedSpawnLocation(World world, Random random)
    {
   
    return new Location(world, 0, 64, 0);
    }
 
}

Here's once again what I'm trying to do:

Code:

        WorldCreator c = new WorldCreator(worldname);
        World world = c.createWorld();    

I have tried this btw:

Code:

c.generator(new NullGenerator());

But that didn't work either.

Does anyone know what's wrong here? It would be a great help for me.

Is it just not working (doing nothing) or giving errors (in console)?
if so print out the console message

 

Nope no errors. It makes the world like you'd expect but it uses the default generator.

 

Not experienced with chunk generation mabe
someone else on the forums may help you

 

Have you tried overriding the getDefaultChunkGenerator in the NullTerain plugin ;D

 

I'm not sure how that would help me though?

 

well in the snippet at replt #5 you used getDefaultWorldGenerator(). If you don't override that to get the instance, it would fail (and give you the default worldgenerator ;3). Btw can you post what you tried using c.generator(new NullGenerator())?

 

Ah that makes sense yeah (can't believe I forgot that.)

About using: c.generator(New NullGenerator()). All I did was put that line of code there to define the chunkgenerator, I had the 'NullGenerator' class (wich extends ChunkGenerator) copied over to my project.

I'm going to try overriding it right now, and see if it works

When using this method:

Code:

    @Override
    public org.bukkit.generator.ChunkGenerator getChunkGenerator(String generator, String generatorID, String worldName) {
    if (generator == null) {
    return null;
    }
 
    Plugin myPlugin = this.plugin.getServer().getPluginManager().getPlugin(generator);
    if (myPlugin == null) {
    return null;
    } else {
    return myPlugin.getDefaultWorldGenerator(worldName, generatorID);
    }
    }

It keeps telling me that it must override or implement a supertype method, as a quickfix Eclipse is telling me to remove the @Override. Is there something I need to implement or extend in the class for this to work, like implementing/extending chunkgenerator?

I ment getDefaultWorldGenerator() inside the plugin

 

Well it should be since multiverse is recommending NullTerrain to be used with their generator command. I've looked through its source code and it does have it in there.

The plugin does give me an error on startup saying there's no such method as getconfiguration(..) but I figured after looking into the source code that only makes it so that it doesn't log its version number to the console in onEnable as it all works fine if I implement 'NullTerrain' as generator in bukkit.yml.

Let me get the mainclass of NullTerrain.

Here's a link to its source code (it's really small):

For your plugin:

Code:java

public ChunkGenerator getGenerator(String generator)
{
    if(generator == null)
    {
        return null;
    }
    JavaPlugin generatorPlugin = Bukkit.getPluginManager().getPlugin(generator);
    if(generatorPlugin == null)
    {
        return null;
    }
    return generatorPlugin.getDefaultWorldGenerator();
}
