How edit this to place block end portal and set obsidian to bedrock

 

Please use code blocks, thanks

Spoiler: I am dumb and don't know what that is

[PHP]Put your php code here[/PHP]
or for normal code or files that aren't php:
[CODE]Put normal code or file content (e.g. configs) here[/CODE]

Spoiler: Bad words

I am really getting tired from writing this, can people please get a proper working brain...

 

So, you want an end portal on the skyblock island with a the bedrock being obsidian?

Spoiler: This will set bedrock to obsidian

PHP:

public function generateChunk($chunkX, $chunkZ) {
        $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, $z, Block::OBSIDIAN);
                    for ($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);
        }
    }
