WorldBuilder

A world editor plugin designed for production use.

WorldBuilder (WB) is specifically designed to handle multiple world-edit operations efficiently. It is an excellent editor plugin creative-mode like servers (such as MyPlot plugin users). WB is not a fast editor—instead, it is deliberately slows down editor tasks to let the server handle multiple operations concurrently.

WB provides an API for limiting and monitoring world edit operations.

Handling and filtering editor tasks

As a creative-mode server maintainer, disallowing players from editing other's regions and avoiding specific blocks from being spawned can be done using WB's API in the following way:

use cosmicpe\worldbuilder\editor\executor\SetEditorTaskInfo;
use cosmicpe\worldbuilder\event\player\PlayerTriggerEditorTaskEvent;
use pocketmine\block\BlockTypeIds;use pocketmine\math\Vector3;

public function onPlayerTriggerEditorTask(PlayerTriggerEditorTaskEvent $event) : void{
	$player = $event->player;
	$task = $event->instance->info;
	if($task instanceof SetEditorTaskInfo){
		if($task->block->getTypeId() === BlockTypeIds::TNT){
			$event->cancel();
			$player->sendMessage("Setting " . $task->block->getName() . " is not allowed!");
		}
		
		// allow modifying sections between these 2 points
		$p1 = new Vector3(0, 0, 0);
		$p2 = new Vector3(100, 255, 100);
		if($task->x1 < $p1->x || $task->x2 > $p2->x || $task->y1 < $p1->y || $task->y2 > $p2->y || $task->z1 < $p1->z || $task->z2 > $p2->z){
			$event->cancel();
			$player->sendMessage("You cannot build outside your allocated region!");
		}
	}else{
		// disallow players from using anything else besides //set
		$event->cancel();
		$player->sendMessage("This operation is not allowed on the server.");
	}
}

Monitoring editor tasks

use cosmicpe\worldbuilder\editor\executor\EditorTaskInfo;
use cosmicpe\worldbuilder\editor\task\listener\EditorTaskListener;

class MyEditorTaskListener implements EditorTaskListener{

	public function onRegister(EditorTaskInfo $info) : void{
		// Called after PlayerTriggerEditorTaskEvent has been triggered and the
		// event hasn't been cancelled.
	}

	public function onCompleteFraction(EditorTaskInfo $info, int $completed, int $total) : void{
		// $player->sendPopup($task->getName() . " completed: " . sprintf("%0.2f", ($completed / $total) * 100) . "%");
	}

	public function onCompletion(EditorTaskInfo $info) : void{
		// $player->sendPopup($task->getName() . " completed!");
	}
}

...and then register it to an editor task!

use cosmicpe\worldbuilder\event\player\PlayerTriggerEditorTaskEvent;

/**
 * @param PlayerTriggerEditorTaskEvent $event
 * @priority MONITOR
 */
public function onPlayerTriggerEditorTask(PlayerTriggerEditorTaskEvent $event) : void{
	$event->instance->registerListener(new MyEditorTaskListener());
}

Executing edit operations

An edit operation (e.g., //copy, //paste, etc.) may be programmatically executed by building an EditorTaskInfo object and executing it. An EditorTaskInfo implementation exists for every editor operation.

use cosmicpe\worldbuilder\editor\executor\SetEditorTaskInfo;
use cosmicpe\worldbuilder\editor\task\listener\EditorTaskOnCompletionListener;
use cosmicpe\worldbuilder\Loader;
use pocketmine\block\VanillaBlocks;
use pocketmine\Server;

$world = Server::getInstance()->getWorldManager()->getDefaultWorld();
$task = new SetEditorTaskInfo(
	world: $world,
	x1: 0,
	y1: 0,
	z1: 0,
	x2: 100,
	y2: 255,
	z2: 100,
	block: VanillaBlocks::STONE(), // fill this area with stone
	generate_new_chunks: true
);

/** @var Loader $plugin */
$plugin = Server::getInstance()->getPluginManager()->getPlugin("WorldBuilder");

echo "Task started";
$instance = $plugin->getEditorManager()->buildInstance($task);
$instance->registerListener(new EditorTaskOnCompletionListener(function(SetEditorTaskInfo $info) : void{
	echo "Task completed";
}));
$plugin->getEditorManager()->push($instance);
