In my main mod file with my ore generation order, this is what the code looks like.

@EventHandler
	public static void init(FMLInitializationEvent event)
	{
		GameRegistry.registerWorldGenerator(new FireOreGen(), 0);
		GameRegistry.registerWorldGenerator(new WaterOreGen(), 0);
	}

The problem is, only the WaterOreGen works. When i put the FireOreGen line after the WaterOreGen line, only the FireOreGen works.

Am I supposed to somehow generate multiple types of ores in one Generator? Or am I doing something wrong in my main mod file? Thanks in advance!

You dont have to. But that is what most people do. Use a switch case statement or an if statement.

Post your code for the FireOreGen and WaterOreGen classes

Here is the FireGen code:

 

package com.cherrylime.minecraftimproved.gen;

import java.util.Random;

import com.cherrylime.minecraftimproved.blocks.BlockBase;
import com.cherrylime.minecraftimproved.init.ModBlocks;

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

public class FireOreGen implements IWorldGenerator
{
    private WorldGenerator fire_ore;
    
    public FireOreGen()
    {
        fire_ore = new WorldGenMinable(ModBlocks.FIRE_ORE.getDefaultState(), 9);
    }
    
    
    @Override
    public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator,
            IChunkProvider chunkProvider) {
        switch(world.provider.getDimension())
        {
        case 0:
            
            runGenerator(fire_ore, world, random, chunkX, chunkZ, 10, 0, 50);
            
            
            break;
            
        case 1:
            
            break;
            
        case -1:
            
            break;
        }
        
    }
    
    private void runGenerator(WorldGenerator gen, World world, Random rand, int chunkX, int chunkZ, int chance, int minHeight, int maxHeight)
    {
        if(minHeight > maxHeight || minHeight < 0 || maxHeight > 256) throw new IllegalArgumentException("Ore generated off limits");
        int heightDiff = maxHeight - minHeight + 1;
        
        for(int i = 0; i < chance; i++)
        {
            int x = chunkX * 16 + rand.nextInt(16);
            int y = minHeight + rand.nextInt(heightDiff);
            int z = chunkZ * 16 + rand.nextInt(16);
            
            gen.generate(world, rand, new BlockPos(x, y, z));
        }
    }
    
}
 

And here is the WaterGen code:

 

package com.cherrylime.minecraftimproved.gen;

import java.util.Random;

import com.cherrylime.minecraftimproved.blocks.BlockBase;
import com.cherrylime.minecraftimproved.init.ModBlocks;

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

public class WaterOreGen implements IWorldGenerator
{
    private WorldGenerator water_ore;
    
    public WaterOreGen()
    {
        water_ore = new WorldGenMinable(ModBlocks.WATER_ORE.getDefaultState(), 9);
    }
    
    
    @Override
    public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator,
            IChunkProvider chunkProvider) {
        switch(world.provider.getDimension())
        {
        case 0:
            
            runGenerator(water_ore, world, random, chunkX, chunkZ, 10, 0, 50);
            
            
            break;
            
        case 1:
            
            break;
            
        case -1:
            
            break;
        }
        
    }
    
    private void runGenerator(WorldGenerator gen, World world, Random rand, int chunkX, int chunkZ, int chance, int minHeight, int maxHeight)
    {
        if(minHeight > maxHeight || minHeight < 0 || maxHeight > 256) throw new IllegalArgumentException("Ore generated off limits");
        int heightDiff = maxHeight - minHeight + 1;
        
        for(int i = 0; i < chance; i++)
        {
            int x = chunkX * 16 + rand.nextInt(16);
            int y = minHeight + rand.nextInt(heightDiff);
            int z = chunkZ * 16 + rand.nextInt(16);
            
            gen.generate(world, rand, new BlockPos(x, y, z));
        }
    }
    
}

You should switch over to using one WorldGenerator, create two fields in one class and call runGeneration on both.

Thank you! It worked!
