Can someone please help me with ore generation, and making my ore spawn as often as coal. I have the file but I don't really understand it. I just looked at an example and copied it, but I want to know how to make it spawn more often and at different levels.

You're better off asking in the COG thread than the Forge forums this board is to help modders mod, not mod users use mods.

package com.puplet.pupletmod;

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 WorldGeneratorPuplet implements IWorldGenerator{

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);
	}
}




private void generateSurface(World world, Random random, int chunkX,int chunkZ) {
	for (int i = 0; i < 13; i++){
		int randPosX = chunkX + random.nextInt(16);
		int randPosY = random.nextInt(40);
		int randPosZ = chunkZ +random.nextInt(16);

		(new WorldGenMinable(PupletMod.pupletOre, 10)).generate(world, random, randPosX, randPosY, randPosZ);

	}

}

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

}

I just want to know which line affects the amount it spawns and on what level

Spawn Level:

int randPosX = chunkX + random.nextInt(16);
int randPosY = random.nextInt(40);
int randPosZ = chunkZ +random.nextInt(16);

 

Amount:

(new WorldGenMinable(PupletMod.pupletOre, 10)).generate(world, random, randPosX, randPosY, randPosZ);

 

Spawn Chance:

for (int i = 0; i < 13; i++)

To increase the chance I should put i<100, right?

Why don't you try it and see?

 

coolboy4531's post broke it down pretty well, so you should notice that the y position is the height at which your ore will spawn. You are using rand.nextInt(40), which returns a value between 0 and 39, meaning your ore will be in those layers of the world, and those layers only. Look deeper if you're not finding it.

I am not sure you unterstood him right.

 

Whoops, my mistake.  I connected the title with the mod of the same name and wasn't able to see past it.
