How to spawn structures in the nether(screenshots)

[TheRPGAdventurer]

So guys I thought my code wasn't working til I found the issue. You see, when  I spawn my structure in the nether, It spawns above the bedrock on the uppermost layer of the nether not on the world below it. I have screenshots.

	public void generateNestAtNether(World world, Random random, int chunkX, int chunkZ) {		
		int x = chunkX * 16 + random.nextInt(16);
		int z = chunkZ * 16 + random.nextInt(16);
		int xy = x >> 4;
		int zy = z >> 4;
		int height = world.getChunkFromChunkCoords(xy, zy).getHeight(new BlockPos(x & 15, 0, z & 15));
		int y = height - 1;
		BlockPos pos = new BlockPos(chunkX, y, chunkZ);
		
			if(world.getBiomeForCoordsBody(new BlockPos (x,y,z)).getBiomeClass().equals(BiomeHell.class)) {
				if((random.nextInt(120) + 1) <= 1) {
					boolean place = true;
		
					for(int Y = 0; Y < 3; Y++) {
						for(int Z = 0; Z < 7; Z++) {
							for(int X = 0; X < 7; X++) {
								if(world.getBlockState(new BlockPos(X + x, Y + y + 1, Z + z)).getBlock() != Blocks.AIR) {
									place = false;
								}
							}
						}
					}
					
					if(place) {
						dragonNestNether.generate(world, random, new BlockPos(x,y,z));
				}       Utils.getLogger().info("Nest here at: " + dragonNestNether.generate(world, random, new BlockPos(x,y,z)));
			}
		}
    } 
}

			}
		}
    } 
}

 

Also, how do I make my code give me the exact location of the structure instead of saying "Nest here at true" in the console.

Utils.getLogger().info("Nest here at: " + dragonNestNether.generate(world, random, new BlockPos(x,y,z)));

The getHeight method returns (generally) the topmost solids block. In the nether, that's the bedrock on top of the world. If you want your structure to generate at a different altitude, you need to use a different y co-ordinate.

The generate method returns a boolean. If you want to print a BlockPos, then put a BlockPos inside the logger statement.
