Hey all, I am having a little trouble (okay, a lot of trouble). I just finished coding for a new ore I want to add with my mod, got it so that I could test and everything, and then I get his error.

Now, when I take out this line of code the game loads, but no ore is generated.

 

GameRegistry.registerWorldGenerator(new CeepWorldGeneration());

 

 

Any help is really appreciated.

Howza 'bout your CeepWorldGeneration class.

Here you go.

 

 

package ceepCraft;

 

import java.util.Random;

 

import net.minecraft.world.World;

import net.minecraft.world.chunk.IChunkProvider;

import net.minecraft.world.gen.feature.WorldGenMinable;

import cpw.mods.fml.common.IWorldGenerator;

 

public class CeepWorldGeneration implements IWorldGenerator{

 

@Override

public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider) {

// TODO Auto-generated method stub

 

switch(world.provider.dimensionId){

case -1:

    generateNether(world, random, chunkX * 16, chunkZ * 16);

    break;

case 0:

    generateSurface(world, random, chunkX * 16, chunkZ * 16);

    break;

case 1:

    generateEnd(world, random, chunkX * 16, chunkZ * 16);

    break;

 

}

 

 

}

 

private void generateEnd(World world, Random random, int chunkX, int chunkZ) {

// TODO Auto-generated method stub

 

}

 

private void generateSurface(World world, Random random, int chunkX, int chunkZ) {

// TODO Auto-generated method stub

 

for(int c = 0; c<16; c++){

int x = chunkX + random.nextInt(16);

int y = random.nextInt(60);

int z = chunkZ + random.nextInt(16);

(new WorldGenMinable(Ceepe.JorganOre.blockID, 10)).generate(world, random, x, y, z);

}

 

}

 

 

private void generateNether(World world, Random random, int chunkX, int chunkZ) {

// TODO Auto-generated method stub

 

}

}

 

 

 

And, when I add in a second block, it names them both the same thing, here is my updated Ceepe code.

 

 

package ceepCraft;

@SidedProxy(clientSide="ceepCraft.Ceep.client.ClientProxy",serverSide="ceepCraft.Ceep.CommonProxy")

public static CommonProxy proxy;

 

public static String modid;

 

    @PreInit

    public void preInit(FMLPreInitializationEvent event) {

 

    }

    public final static Block JorganOre = new JorganOre(501,1, Material.iron);;

    public static Block CeeygOre= new CeeygOre(502, 2, Material.iron);

    @Init

    public void load(FMLInitializationEvent event) {

 

            LanguageRegistry.addName(CeeygOre, "Ceeyg Ore");

            MinecraftForge.setBlockHarvestLevel(CeeygOre, "pickaxe", 3);

            GameRegistry.registerBlock(CeeygOre, "ceeygore");

 

            LanguageRegistry.addName(JorganOre, "Jorgan Ore");

            MinecraftForge.setBlockHarvestLevel(JorganOre, "pickaxe", 3);

            GameRegistry.registerBlock(JorganOre, "jorganore");       

 

 

            proxy.registerRenderThings();

    }

   

 

    @PostInit

    public void postInit(FMLPostInitializationEvent event) {

            // Stub Method

 

}

 

}

 

 

 

 

Help anyone?

You waited two hours. I'm not on all day. Be patient.

 

Anyway, I have a feeling that your Ceepe.JorganOre might not be initialized. That's the only thing that would be causing an NPE.

I wasn't referring to just you, I understand, I was just hoping that someone else might be able to help. Anyways, I fixed them both, it turns out the tutorial I had based everything off of was using old forge code, it was simply a matter of me adjusting to the new. Thank though.
