I made an Ore Generator but it don't work. My own Ore isn't anywhere in the World. Here my Ore Generator:

public class OreGenerator implements IWorldGenerator {

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

	switch(world.provider.dimensionId){
	case -1: generateNether(world, random, chunkX * 16, chunkZ * 16);
	case  0: generateSurface(world, random, chunkX * 16, chunkZ * 16);
	case  1: generateEnd(world, random, chunkX * 16, chunkZ * 16);
	}

}

private void generateSurface(World world, Random random, int x, int z) {

}

private void generateEnd(World world, Random random, int x, int z) {

}

private void generateNether(World world, Random random, int x, int z) {
	oreGen(ChemMix.leavyumOre, world, random, x, z, 16, 16, 100, 15, 100, 60);
}

public void oreGen(Block b, World w, Random r, int posX, int posZ, int maxX, int maxZ, int maxAder, int spawnChance, int minY, int maxY){

	int diffMinMaxY = maxY - minY;

	for(int i = 0; i < spawnChance; i++){

		int posiX = posX + r.nextInt(maxX);
		int posiY = minY + r.nextInt(diffMinMaxY);
		int posiZ = posZ + r.nextInt(maxZ);

		(new WorldGenMinable(b, maxAder)).generate(w, r, posiX, posiY, posiZ);
	}
}


}

 

I registered the Generator in the postInit part:

GameRegistry.registerWorldGenerator(new OreGenerator(), 1);

Just to check:

You know your ore is only generating in the nether, right? And WorldgenMinable only replaces stone, right?

What you could do is make your ore as common as possible by removing the "int spawnChance" and replacing it with a random integer or a specific integer. That's what I do to test my ores, but I have that in my generateSurface() method;

private void generateSurface(World world, Random random, int i, int j) {
	for(int k = 0; k < random.nextInt(124) + 1; k++) {
		int firstBlockXCoord = i + random.nextInt(16);
		int firstBlockYCoord = random.nextInt(44);
		int firstBlockZCoord = j + random.nextInt(16);

		new WorldGenMinable(TaserItemsAndBlocks.Salt_Ore, random.nextInt(10)).generate(world, random, firstBlockXCoord, firstBlockYCoord, firstBlockZCoord);
	}
}

 

Try playing around with the y-coord integer too, to see if it can spawn.

Everyone has their own way of doing things, and I've found this to work 100% of the time for me, but I hope this helps you.

 

Thanks,

Will.

 

EDIT: Since you're using 1.7.10 this code may be different, so just be aware, I'm using 1.8 code.

Now I changed it to generateSurface but now my Minecraft crashes:

You passed a non-positive number to

Random#nextInt

in

OreGenerator#oreGen

(line 44). The code in your original post uses 100 as the minimum y position and 60 as the maximum y position, so

maxY - minY

is negative.

Thanks Very Much^^

 

Now there is a NullPointerException but why?!

http://pastebin.com/rsD0LpUZ

You created a

WorldGenMinable

with a

null

Block

on line 47 of

OreGenerator

.

But the block isn't null this is my own Block which I registered int the preInit Part

Ore I am very stupid at the moment

I solved it on my own....I didn't set an Unlocalized Name for the Block so that it was null
