[1.11] World Generation

[King_of_Mines1]

I am trying to make a world generator for one of my blocks but it isn't generating anything.

 

World Gen Class:

package me.kingofmines1.testmod.worldgen;

import java.util.Random;

import me.kingofmines1.testmod.init.ModBlocks;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkGenerator;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import net.minecraft.world.gen.feature.WorldGenerator;
import net.minecraftforge.fml.common.IWorldGenerator;

public class FoodCrateGen implements IWorldGenerator {

	private WorldGenerator foodcrate_overworld;
	
	public FoodCrateGen() {
		foodcrate_overworld = new WorldGenMinable(ModBlocks.foodcrate.getDefaultState(), 1);
	}
	
	private void runGenerator(WorldGenerator generator, World world, Random rand, int chunk_X, int chunk_Z, int chancesToSpawn, int minHeight, int maxHeight) {
		if (minHeight < 0 || maxHeight > 256 || minHeight > maxHeight)
			throw new IllegalArgumentException("Illegal Height Arguments for WorldGenerator");

		int heightDiff = maxHeight - minHeight + 1;
		for (int i = 0; i < chancesToSpawn; i ++) {
			int x = chunk_X * 16 + rand.nextInt(16);
		        int y = minHeight + rand.nextInt(heightDiff);
		        int z = chunk_Z * 16 + rand.nextInt(16);
		        generator.generate(world, rand, new BlockPos(x, y, z));
		}
	}
	
	@Override
	public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator,
			IChunkProvider chunkProvider) {
		
		switch(world.provider.getDimension()) {
		case 0:
			this.runGenerator(foodcrate_overworld, world, random, chunkX, chunkZ, 100, 50, 90);
		}
		
	}

	
	
}

 

Server Proxy Class:

package me.kingofmines1.testmod.proxy;

import me.kingofmines1.testmod.util.Utils;
import me.kingofmines1.testmod.worldgen.FoodCrateGen;
import net.minecraftforge.fml.common.registry.GameRegistry;

public class ServerProxy implements CommonProxy {

	@Override
	public void init() {
		
	}
	
	@Override
	public void genInit() {
		GameRegistry.registerWorldGenerator(new FoodCrateGen(), 0);
		Utils.getLogger().info("Registered Food Crate Generator");
	}

}

 

Common Proxy Class:

package me.kingofmines1.testmod.proxy;

public interface CommonProxy {
	
	public void init();

	public void genInit();
		
}

 

 

Once I get the generator working I want to make it so that my block only spawns on top of grass on the surface.

Where do you call the genInit() method? Is your runGenerator method actually getting called?

int y = minHeight + rand.nextInt(heightDiff);

int z = chunk_Z * 16 + rand.nextInt(16);

 

 

It's also a good idea to, whenever generating stuff in the world, offset the gen position by 8 on the X/Z axes. If you don't, you could run into cascading chunk gen problems.

Im calling the genInit() method in my main class

 

@EventHandler
	public void init(FMLInitializationEvent event) {
		Utils.getLogger().info("Initialize");
		
		OreDictionaryHandler.registerOreDictionary();
		RecipeHandler.registerCraftingRecipes();
		RecipeHandler.registerSmeltingRecipes();
		proxy.genInit();
	}

Did you get it to work? Because i need a similar thing to spawn an ore underground and have been breaking my head for an hour now

Tell us what you saw happening when you stepped into proxy.genInit() in the debugger.
