Okay, so I have come to the conclusion that watching a 1.7 tutorial is bad for 1.8, so does anyone know any tutorials for custom structures for 1.8?

 

I created a custom structure for Minecraft 1.8 and used MCEdit to get the schematic, and then Jajo_11's Schematic to Structure Converter.

My main problem is that inside the structure's class, the .getBlock it used many times, giving me an error.

 

Structure's Class

 

public class SwirlRock extends WorldGenerator
{
protected Block[] GetValidSpawnBlocks()
{
	return new Block[]
	{
		Blocks.grass,
	};
}

public boolean LocationIsValidSpawn(World world, int x, int y, int z)
{

>>>> 	Block checkBlock = world.getBlock(x, y - 1, z);
>>>>	Block blockAbove = world.getBlock(x, y , z);
>>>>	Block blockBelow = world.getBlockstate(x, y - 2, z);


	for (Block i : GetValidSpawnBlocks())
	{
		if (blockAbove != Blocks.air)
		{
			return false;
		}
		if (checkBlock == i)
		{
			return true;
		}
		else if (checkBlock == Blocks.snow_layer && blockBelow == i)
		{
			return true;
		}
		else if (checkBlock.getMaterial() == Material.plants && blockBelow == i)
		{
			return true;
		}
	}
	return false;
}

public boolean generate(World world, Random rand, int x, int y, int z)
{
	int i = rand.nextInt(1);

	if(i == 0)
	{
	    generate_r0(world, rand, x, y, z);
	}

       return true;

}

public boolean generate_r0(World world, Random rand, int x, int y, int z)
{
	if(!LocationIsValidSpawn(world, x, y, z) || !LocationIsValidSpawn(world, x + 0, y, z) || !LocationIsValidSpawn(world, x + 0, y, z + 0) || !LocationIsValidSpawn(world, x, y, z + 0))
	{
		return false;
	}

>>>	>	world.setBlock(x + 0, y + 0, z + 0, ModBlocks.swirl_rock, 1, 3);
	return true;

}

}

World#getBlock

and

World#setBlock

were replaced by

World#getBlockState

and

World#setBlockState

, respectively. These take a

BlockPos

instead of individual coordinates and take/return an

IBlockState

instead of a

Block

.

 

Use

IBlockState#getBlock

to get the

Block

represented by a state.

 

Use

Block#getDefaultState

to get the default state of a block, then chain

IBlockState#withProperty

calls to get an

IBlockState

with the specified property values.
