WorldGen error.

[CJCutrone9]

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.

Any help is really appreciated.

Howza 'bout your CeepWorldGeneration class.

Here you go.

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) {

}

}

 

 

 

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

Help anyone?

[ObsequiousNewt]

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.

[CJCutrone9]

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.
