Claiming chunks around a chunk

If the title doesnt make sense ill try yo explain it better, if I have 1 chunk, I want to claim or save they x and z's of the chunks around it 3x3 chunks I have the core chunk then I want to create a 3x3 chunks around it.

Why not just use some simple math?

leftTop = world.getChunkAt(chunk.getX() - 1, chunk.getZ() - 1);
leftMiddle = world.getChunkAt(chunk.getX() - 1, chunk.getZ());
leftBottom = world.getChunkAt(chunk.getX() - 1, chunk.getZ() + 1);

middleTop = world.getChunkAt(chunk.getX(), chunk.getZ() - 1);
middleBottom = world.getChunkAt(chunk.getX(), chunk.getZ() + 1);

rightTop = world.getChunkAt(chunk.getX() + 1, chunk.getZ() - 1);
rightMiddle = world.getChunkAt(chunk.getX() + 1, chunk.getZ());
rightBottom = world.getChunkAt(chunk.getX() + 1, chunk.getZ() + 1);

Or if you only need the surrounding chunks and don't need to know which is which use a for loop

Code:java

for (int x = -1; x <= 1; x++)
{
    for (int z = -1; z <= 1; z++)
    {
        Chunk chunk = world.getChunkAt(origChunk.getX() + x, origChunk.getZ() + z);
    }
}

If you can get a Location from within the center chunk you can add/subtract 16 to the X/Z values of that Location and then use the new Location to grab the surrounding chunks. For example, add 16 to the X of the original Location and grab the chunk at the new location. Then add 16 to the X and Z of the original Location and grab the chunk at that Location. Then just add 16 to the Z of the original Location and grab the chunk at that Location.

I'm not going to go through all eight of the chunks but if you don't get the idea I can elaborate.

 

Thanks guys! ill be sure to use whichever fits best with my code, ill try it out shortly.
