So I've been following the tutorials on World Generation on the wiki and it doesn't seem to work (perhaps not with 1.7.2?) and I can't see why?

I'm registering my World Generators under FMLPreInitializationEvent and here is my generator https://gist.github.com/anonymous/6fcac69c2bbf1e534e0c

You have to multiply the chunkX and chunkZ by 16. Or just use my class:

Then just use the addOre method in your Registry...

            int x = chunkX + rand.nextInt(16);
            int y = rand.nextInt(max - min) + min;
            int z = chunkZ + rand.nextInt(16);
            worldGen.generate(world, rand, x, y, z);

            OreData ore = iter.next();
            if (TerrainGen.generateOre(world, rand, ore.oreGen, chunkX, chunkZ, OreGenEvent.GenerateMinable.EventType.CUSTOM))
                genStandardOre(ore.count, world, ore.oreGen, rand, chunkX * 16, chunkZ * 16, ore.min, ore.max);
        }
    }
}

 

 

EDIT: I forgot the package

I'm wondering why everybody following some tutorial is making the same mistake in oreGen? Maybe we should blacklist the tutorial.

The tutorial is fine but somebody should add the *16...

Sorry, but...when you say use the addOre with your registry...what do you mean? For my ore I've got:

RadialOre = new RadialOre().setBlockName("radialore").setHardness(5.0F).setResistance(5.0F).setLightLevel(0.8F).setStepSound(Block.soundTypeStone).setCreativeTab(RadialTabs).setBlockTextureName(modid + ":radialore");
	GameRegistry.registerBlock(RadialOre, "radialore").addOre(RadialOre);
	RadialOre.setHarvestLevel("pickaxe", 3);

That gives me an error, though. Am I putting it in the wrong spot?

SureenInk, Busti is referring to the Forge OreDictionary (i believe). If you are creating new ores, you would do well to register them in the Ore registry so other mods can use them in recipes, too. Or simply not have a conflict about it when there are more than 1 lead ores in the game.

Sorry...I'm horribly new at this...so then I just have to add [codepublic static void oreRegistration()
{
	OreDictionary.registerOre("radialore", RadialOre);
}

I'm sorry...I really am new at this (just started the other day), so I'm still very confused x.x
