Hello,

I tried to add an ore to the world gen and I followed the common tutorials. I tried to add some structure to it to make it easier, but somehow it isn't working:

Registration:

public static void Init() {
        //Generators
        OreGen oreGen = new OreGen();
        oreGen.addOre(block_CopperOre, 10);
        GameRegistry.registerWorldGenerator(oreGen, 500);
}

 

Gen Class:

            WorldGenMinable ore = iter.next();
            if (TerrainGen.generateOre(world, random, ore, chunkX, chunkZ, OreGenEvent.GenerateMinable.EventType.CUSTOM))
                genStandardOre(20, world, ore, random, chunkX, chunkZ, 0, 96);
        }

}

I also have this problem, my ore and trees wont generate at all. My code is very similar to yours, I also register my World Generators under the FMLIntializationEvent, I'm guessing you're doing something similar?

Yes I am. The generate method gets called but nothing generates. It also takes a very long time but i cant imagine where the delay comes from.

When I do it with my blocks each chunk takes about 10 seconds more to generate but when I do it with a Vanilla block it doesn't. Even though nothing is really generating

You need to multiply chunkX and chunkZ by 16 before passing it on to the other generate methods.

Change this:

    genStandardOre(20, world, ore, random, chunkX, chunkZ, 0, 96);

to this:

    genStandardOre(20, world, ore, random, chunkX*16, chunkZ*16, 0, 96);

*ahem* bitshift *ahem*

The multiply will automagically get implemented by a <<4 in the JVM optimizer (Bytecode compiler), no need to fret. Same as divide by constant power of 2.
