Skyblock island generator

What is the code to generate an island like chunk? i only know how to create a box

Code:

 $chunk = $this->level->getChunk($chunkX, $chunkZ);
        $chunk->setGenerated();
        if ($chunkX % 20 == 0 && $chunkZ % 20 == 0) {
            for ($x = 0; $x < 16; $x++) {
                for ($z = 0; $z < 16; $z++) {
                    $chunk->setBlock($x, 0, $z, Block::BEDROCK);
                    for ($y = 1; $y <= 3; $y++) {
                        $chunk->setBlock($x, $y, $z, Block::STONE);
                    }
                    $chunk->setBlock($x, 4, $z, Block::DIRT);
                    $chunk->setBlock($x, 5, $z, Block::GRASS);
                }
                Tree::growTree($this->level, $chunkX * 16 + 8, 6, $chunkZ * 16 + 8, $this->random, 0);
            }
            $chunk->setX($chunkX);
            $chunk->setZ($chunkZ);
            $this->level->setChunk($chunkX, $chunkZ, $chunk);
        }

 

I assume you want to create an island that looks like this:

Code:

                       %%%%%
                     %%%%%%%%%
                    %%%%%%%%%%%
                    %%%%%%%%% %
                    %%%%%%%%%%%
                        +-+
                        | |
                        | |
                        | |
                        | |
+-+---------------------+-+-----+--+
  |                             |
  +--+-----------------------+--+
     |                       |
     |                       |
     +---+---------------+---+
         |               |
         |               |
         +--+---------+--+
            |         |
            +-+-----+-+
              |     |
              +-----+
                +-+

If so, you can make a loop that decreases the size of the square by two on every run and changes the x, y and z start coordinates to fit the new size.

 

yes like that, but i cant seem to figure out how :/ ill try though, if you figure out how then hmu

 

nvm i got it
