I tried this in my generate method in my world generation class:

		case(0):		
			if(world.getBiome(new BlockPos(chunkX, 64, chunkZ + random.nextInt(16))).getClass().equals(MineralBiome.class)) {
				generateHuge(random, chunkX, chunkZ, world, chunkGenerator, chunkProvider);
				break;
			}
			generateOverworld(random, chunkX, chunkZ, world, chunkGenerator, chunkProvider);
			break;

And it worked until I made the biome have less weight, and it stopped generating. How can I have special generation so it works?

First of all as the variable names suggest these are chunk positions, not block positions. You need to left-shift these by 4 to translate to block positions. Also what is up with this random.nextInt(16)? Why is it there? Why is it 16? Why is it Z only?

You could just do a direct comparason of objects(world.getBiome(...) == YourBiomes.MINERAL_BIOME)

 

 

Thank you. that really helped
