About
Hawk is a PHP library to get and/or replace blocks and get and/or delete entities in Minecraft region files. This allows the user to replace blocks or delete entities that will crash the server when loaded.
Currently, following versions are supported:
1.12+ for entities
1.16+ for blocks
Installation
composer require aternos/hawk
Usage
Class File
How to get a file from disk:
$file = new File("your/region/file");
How to use setContent() to set up a file stream and getContent() to get the content out of the stream:
$file = new File(); $file->setContent(file_get_contents("your/region/file")); $file->setFileName("your/file/name"); "...do stuff here..." $contentToBeWritten = $file->getContent();
Class Hawk
Setups:
Setup for blocks and block entities in any supported version:
// New block coordinates $blockPos = new McCoordinates3D(1, 2, 3); // Path to your region file and calculating the filename from the coordinates $inputPath = "/your/world/region/directory"; $blockFiles[] = new File($inputPath . "/" . Region::getRegionFileNameFromBlock($blockPos)); // Instantiating Hawk only with blockFiles $hawk = new Hawk(blockFiles: $blockFiles);
Setup for entities prior 1.17:
// New entity coordinates $entityPos = new McCoordinatesFloat(1.2, 2.3, 3.4); // Path to your region file and calculating the filename from the coordinates $inputPath = "/your/world/region/directory"; $entitiesFiles[] = new File($inputPath . "/" . Region::getRegionFileNameFromBlock(McCoordinatesFloat::get3DCoordinates($entityPos))); // Instantiating Hawk only with blockFiles because entities used to be in the same file $hawk = new Hawk(blockFiles: $entitiesFiles);
Setup for entities starting from 1.17:
// Path to your entities directory and calculating the filename from the coordinates $inputPath = "/your/world/entities/directory"; $entitiesFiles[] = new File($inputPath . "/" . Region::getRegionFileNameFromBlock(McCoordinatesFloat::get3DCoordinates($entityPos))); $hawk = new Hawk(entitiesFiles: $entitiesFiles);
How to read a block:
$block = $hawk->getBlock($blockPos);
How to replace a block at x = 1, y = 2, z = 3 with wool(default is minecraft:stone):
$hawk->replaceBlock($blockPos, "minecraft:wool"); $hawk->save();
Get all entities in a specific chunk:
$entities = $hawk->getAllEntitiesFromChunk(McCoordinatesFloat::get3DCoordinates($entityPos));
How to get all entities next to float coordinates (there could be more than just one):
$entities = $hawk->getEntities($entityName,$entityPos);
How to delete an entity:
$entities = $hawk->getEntities($entityName,$entityPos); $hawk->deleteEntity($entities[0]); $hawk->save();
Get all block entities in a specific chunk:
$entities = $hawk->getAllBlockEntitiesFromChunk(McCoordinatesFloat::get3DCoordinates($entityPos));
How to get all block entities next to float coordinates (there could be more than just one):
$entities = $hawk->getBlockEntities($entityName,$entityPos);
How to delete a block entity:
$entities = $hawk->getBlockEntities($entityName,$entityPos); $hawk->deleteBlockEntity($entities[0]); $hawk->save();

Class Region
A region object represents a Minecraft region file. The main tasks of a region object is to read/decompress and write/compress chunks from/to its region file. Additionally, it provides static functions to calculate region coordinates and its file name.
Methods
Name | Return type | Description |
---|---|---|
static getRegionFileNameFromBlock(McCoordinates3D $coordinates) | string | Get region file name out of block coordinates |
static getRegionCoordinatesFromFile(AbstractFile $file) | McCoordinates2D | Get region coordinates from file name |
static getRegionCoordinatesFromBlockCoordinates(McCoordinates3D $coordinates) | McCoordinates2D | Get region coordinates from block coordinates |
static getRegionCoordinatesFromChunkCoordinates(McCoordinates2D $coordinates) | McCoordinates2D | Get region coordinates from chunk coordinates |
Class Chunk
A chunk object represents a Minecraft chunk in Mojangs chunk format. The main task of a chunk object is to replace the sections tag of the NBT structure, compress the new chunk data and provide it to its region. Additionally, it provides a static function to calculate chunk coordinates.
Methods
Name | Return type | Description |
---|---|---|
static getChunkCoordinates(McCoordinates3D $coordinates) | McCoordinates2D | Get chunk coordinates from block coordinates |
Class Section
A section object represents a single section tag.
Methods
Name | Return type | Description |
---|---|---|
static getSectionCoordinates(McCoordinates3D $coordinates) | McCoordinates3D | Get section coordinates from block coordinates |
static getBlockCoordinates(McCoordinates3D $coordinates) | McCoordinates3D | Get block coordinates relative to its section |
