I tried to make my ores generate in a new world. Although the values are even higher than the ones from coal ore, I can't find the ore.

This is my world generator:

package XFactHD.thermalreactors.common.world;

import XFactHD.thermalreactors.common.TRContent;
import cpw.mods.fml.common.IWorldGenerator;
import net.minecraft.init.Blocks;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import net.minecraft.world.gen.feature.WorldGenerator;

import java.util.Random;

public class TROreGen implements IWorldGenerator
{
    private WorldGenerator genOreUranium;
    private WorldGenerator genOreZirconium;
    private WorldGenerator genOreBoron;

    public TROreGen()
    {
        this.genOreBoron = new WorldGenMinable(TRContent.blockOre, 3, 16, Blocks.stone);
        this.genOreUranium = new WorldGenMinable(TRContent.blockOre, 1, 16, Blocks.stone);
        this.genOreZirconium = new WorldGenMinable(TRContent.blockOre, 2, 16, Blocks.stone);
    }

    @Override
    public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider)
    {
        switch (world.provider.dimensionId)
        {
            case 0: //Overworld
                this.runGenerator(this.genOreBoron, world, random, chunkX, chunkZ, 50, 0, 128);
                this.runGenerator(this.genOreUranium, world, random, chunkX, chunkZ, 50, 0, 128);
                this.runGenerator(this.genOreZirconium, world, random, chunkX, chunkZ, 50, 0, 128);
                break;
            case -1: //Nether

                break;
            case 1: //End

                break;
        }
    }

    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, x, y, z);
        }
    }
}

The generator is registered in the common proxy in FMLInitializationEvent.

Am I just not searching long enough or am I doing something wrong?

I realize this has nothing to do with your question, but what is with people moving all of their FML event code into the common proxy?

 

All I can figure is that you guys all read some tutorial where the author did that "for reasons" that were never explained just because it was their style.

I am orienting myself on other modders and their code on github, but actually you are right, we are just doing it because someone said it. 

Set breakpoints in the methods you think are relevant, and then run in the debugger to see what's happening. If the ores appear to be generating somewhere, write down the block coords and then go see what's actually there.

I tried putting some log output of the coordinates into the runGenerator() method and it still didn't work, then I put the registration in the main mod class and it worked. Seems that my proxy is broken or I am being to dump to fire the start-up events in the proxy. Anyway, it works now. Thank you all for your help.

Aha, for methods in CommonProxy to always execute, you must make sure that ClientProxy and (in your case) ServerProxy call their supers from any methods that they override. Otherwise the overrides intercept the calls so that they never reach common.
