Solved Can I Access Chunk Information?

    I have something in mind that I would like to develop and I need to gain an understanding of chunks.

    I'm having trouble with googling, as I seem to just be finding lots and lots of plugins that have something to do with chunks.

    Anyhoo, before starting my full blown plugin and confusing myself with stuff too complex for learning a single thing, I'd like to make the following plugin:

    Command: /replace <x, y> <x, y,z> <block>

    This will grab chunk x,y and replace block x,y,z with the defined block.

    Do chunks have a way to access via coordinates, or would I need to create a 0,0 reference myself? How could I begin to access them and do they contain a list of contained blocks within for this functionality?

    Any help would be great and I could also use any docs links you may have for me as I seem to be having trouble finding any reference to chunks with bukkit.

  2., int)

    This will be a bit server intensive:
    for (int y = 0; y <= world.getMaxHeight(); y++) { // Loop through every 'y' coordinate until the maximum world height.
        for (int x = 0; x <= 16; x++) { // Every chunk has a size of 16.
            for (int z = 0; z <= 16; z++) { // ^ Same here.
                Block blockAt = chunk.getBlock(x, y, z); // Get the block. I'm not sure if this requires world coordinates or chunk coordinates, but here I'm using chunk coordinates.
                // Do something.

    @stefvanschie Thanks! Done :)

    @KingFaris11 Sorry, I just noticed something.

    Your x/z loops are written as (int x = 0; x <= 16; x++)

    Unless my maths is failing me, should this not be (int x = 0; x < 16; x++) or (int x = 0; x <= 15; x++)? Each chunk is 16x16, so therefore, should I not be getting 0-15 rather than 0-16?

    I don't seem to be getting issues at the moment, but would this cause me issues further down the line?

    edit: same for y too?

  8. Oops my mistake, yes it is < but for the max height, no, I believe it is <=.
