I have no error in my ore generation class, but in the world I can not find the ores

 

ore generation class: https://gist.github.com/anonymous/17fc0032a07a5cd676a9

 

help me please

System.out.println("Ore Spawned Succesfully");

Did that print ?

If not, you may want to check your generator registration.

replace with this:

 

[spoiler]package (modName).world;

import java.util.Random;

import (modName).mod_SecretMod;
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 (ClassName) 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, chunkZ, chunkZ);
            break;
            case 0:
            generateSurface(world, random, chunkX*16, chunkZ*16);
            break;
            case 1:
            generateEnd();
            break;
            }
 		}

private void generateEnd() {

}

private void generateSurface(World world, Random random, int chunkX, int chunkZ) {
for (int i = 0; i < 9; i++){
	int randPosX = chunkX + random.nextInt(16);
	int randPosZ = chunkZ + random.nextInt(16);
	int randPosY = 45 + random.nextInt(5);
	(new WorldGenMinable(mod_(ModName).(ORENAME).blockID, 9)).generate(world, random,randPosX, randPosY, randPosZ);
}





}

private void generateNether(World world, Random random, int chunkX, int chunkZ) {
	for (int i = 0; i < 5; i++){
		int randPosX = chunkX + random.nextInt(16);
		int randPosZ = chunkZ + random.nextInt(16);
		int randPosY = 60 + random.nextInt(10);
		(new WorldGenMinableNether(mod_(ModName).(BlockName).blockID,1, 4)).generate(world, random,randPosX, randPosY, randPosZ);
	}	
}

}

ok now this is my OreGeneration's class  https://gist.github.com/anonymous/4eb674a30b54145f2905

 

.....currently the ores should spawn in a 16x16 chunk, under Y: +45...right?

Your ore may actually be spawning above 45… I could be wrong, but I'm fairly sure that this line

 

int randPosY = 45 + random.nextInt(5);

 

means that your random position Y will always be 45 plus a random number from 0 to 5; basically only 45, 46, 47, 48, 49, or 50. Whatever you wish your ore to spawn above (for example, 1 or 6) and what you wish the ceiling to be (45 I guess) should be used like so:

 

int randPosY = yourMinimumHeight + random.nextInt(yourMaximumHeight - yourMinimumHeight);

 

But don't just take my word for it; I could be wrong. Test it with print streams!

 

After

 

(new WorldGenMinable(ItemList.sorrowfulore.blockID, 9)).generate(world, random,randPosX, randPosY, randPosZ);

 

try to insert this command:

 

System.out.println("(" + randPosX + ", " + randPosY + ", " + randPosZ + ")");

 

This will print out the exact coordinates of your ore upon spawn. Simply check your console for the spawn location and hunt it down!

 

Good luck!

thank you very much !!! I finally understand how it works
