When I start up eclipse and head over to minecraft, my custom ore:blockTinyGemOre, does not spawn. Any help would be appreciated! http://minecraftforge.net/forum/Smileys/default/grin.gif

 

My main thing- or whatever it's called ;-;: http://pastebin.com/p4EsHzDd

TinyGemGeneration class:http://pastebin.com/GdKcdGLZ

First, you need to do a class that implements IWorldGenerator, for example i use this (it also show you how to generate a metada blocks and flowers! )

public class WorldGenMinableMW implements IWorldGenerator {

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

	switch(world.provider.getDimensionId()) {
		case 0:
			generateOverworld(random, world, chunkX*16, chunkZ*16);
			break;
		default:
			generateOverworld(random, world, chunkX*16, chunkZ*16);
	}

}

private void generateOverworld(Random random, World world, int x, int z) {
	addOres(MWBlocks.ruby_ore, world, random, x, z, 4, 5, 0, 16);
	addMetaOres(MWMetadataBlocks.marble.getStateFromMeta(0), world, random, x, z, 6, 15, 0, 30);
	addMetaOres(MWMetadataBlocks.marble.getStateFromMeta(1), world, random, x, z, 6, 15, 0, 30);

	for(int i = 0; i < 2; i++)
	{
		int randPosX = x + random.nextInt(16);
		int randPosY = random.nextInt(250);
		int randPosZ = z + random.nextInt(16);
		(new WorldGenFlowers((BlockFlower)MWBlocks.blue_flower, BlockFlower.EnumFlowerType.DANDELION)).generate(world, random, new BlockPos(randPosX, randPosY, randPosZ));
	}

}

private void addOres(Block block, World world, Random random, int blockXpos, int blockZpos, int MaxVein, int spawnChance, int minY, int maxY) {

	WorldGenMinable minable = new WorldGenMinable(block.getDefaultState(), random.nextInt(MaxVein));
	for (int i = 0; i < spawnChance; i++) {
		int posX = blockXpos + random.nextInt(16);
		int posZ = blockZpos + random.nextInt(16);
		int posY = minY + random.nextInt(maxY - minY);
		minable.generate(world, random, new BlockPos(posX, posY, posZ));
	}

}

private void addMetaOres(IBlockState block, World world, Random random, int blockXpos, int blockZpos, int MaxVein, int spawnChance, int minY, int maxY) {

	WorldGenMinable minable = new WorldGenMinable(block, random.nextInt(MaxVein));
	for (int i = 0; i < spawnChance; i++) {
		int posX = blockXpos + random.nextInt(16);
		int posZ = blockZpos + random.nextInt(16);
		int posY = minY + random.nextInt(maxY - minY);
		minable.generate(world, random, new BlockPos(posX, posY, posZ));
	}

}
}

 

Then you need to register that class as a world generator by doing this in the init event of your main mod class (or in a sub class called by that method)

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

 

After this you're fine and your ores should generate as well

I didn't want a whole new code section, I wanted to know how to fix mine

Thanks anyways

Can someone please help me?? The issue still hasn't been solved... http://minecraftforge.net/forum/Smileys/default/cry.gif

When you "go to Minecraft", are you starting a new world, or are you entering an existing one? Generation only occurs when you visit a virgin chunk. Previously generated chunks will not be changed by new mods with new ore generators.
