libcamera

A small library for handling camera instructions added in Minecraft Bedrock Edition 1.19.30.

See the official documentation for more information.

Installation

Composer

To install this library through composer, run the following command:

composer require wolvesfortress/libcamera

Virion as Phar

The virion for this library can be found on Poggit.

Usage

Here is a basic example on how this library is used:

Registering the virion

In your main plugin file, register the virion like so:

use muqsit\libcamera\libcamera;
use pocketmine\plugin\PluginBase;

class MyPlugin extends PluginBase{

	public function onEnable() : void{
		if(!libcamera::isRegistered()){
			libcamera::register($this);
		}
	}

	// ...
}

Sending instructions

To send instructions to the camera, use the following code:

• Set

use muqsit\libcamera\libcamera;
use muqsit\libcamera\CameraInstruction;
use pocketmine\network\mcpe\protocol\types\camera\CameraPreset;
use pocketmine\network\mcpe\protocol\types\camera\CameraSetInstructionEase;
use pocketmine\network\mcpe\protocol\types\camera\CameraSetInstructionEaseType;
use pocketmine\network\mcpe\protocol\types\camera\CameraSetInstructionRotation;
use pocketmine\network\mcpe\protocol\types\camera\Vector3;
use pocketmine\player\Player;

// ...
if($player instanceof Player && $player->isOnline()){
	/**
	 * @phpstan-param CameraPreset $preset
	 * @phpstan-param CameraSetInstructionEase|null $ease
	 * @phpstan-param Vector3|null $camera_pos
	 * @phpstan-param CameraSetInstructionRotation|null $rot
	 * @phpstan-param Vector3|null $facing_pos
	 */
	CameraInstruction::set(
		preset: libcamera::getPresetRegistry()->registered["target"],
		ease: new CameraSetInstructionEase(
			CameraSetInstructionEaseType::IN_OUT_CUBIC,
			(float) 5.0 // duration (sec)
		),
		camera_pos: null,
		rot: new CameraSetInstructionRotation(
			(float)20.0, //pitch
			(float)180.0 //yaw
		),
		facing_pos: null
	)->send($player);
}

• Fade

use muqsit\libcamera\libcamera;
use muqsit\libcamera\CameraInstruction;
use pocketmine\network\mcpe\protocol\types\camera\CameraFadeInstructionColor;
use pocketmine\network\mcpe\protocol\types\camera\CameraFadeInstructionTime;
use pocketmine\player\Player;

// ...
if($player instanceof Player && $player->isOnline()){
	/** 
	 * @phpstan-param CameraFadeInstructionColor|null $color 
	 * @phpstan-param CameraFadeInstructionTime|null $time
	 */
	CameraInstruction::fade(
		color: new CameraFadeInstructionColor((float)$r,(float)$g,(float)$b),
		time: new CameraFadeInstructionTime((float)$fadeInTime,(float)$stayTime,(float)$fadeOutTime)
	)->send($player);
}

• Target

use muqsit\libcamera\libcamera;
use muqsit\libcamera\CameraInstruction;
use pocketmine\network\mcpe\protocol\types\camera\CameraTargetInstruction;
use pocketmine\math\Vector3;
use pocketmine\player\Player;

// ...
if($player instanceof Player && $player->isOnline()){
	/** 
	 * @phpstan-param Vector3|null $targetCenterOffset
	 * @phpstan-param int $actorUniqueId
	 */
	CameraInstruction::target(
		targetCenterOffset: Vector3::zero(), // no offset
		actorUniqueId: $player->getId() // for example target the player
	)->send($player);
}

• Remove Target

use muqsit\libcamera\libcamera;
use muqsit\libcamera\CameraInstruction;
use pocketmine\player\Player;

// ...
if($player instanceof Player && $player->isOnline()){
	CameraInstruction::removeTarget()->send($player);
}

• Clear

use muqsit\libcamera\libcamera;
use muqsit\libcamera\CameraInstruction;
use pocketmine\player\Player;

// ...
if($player instanceof Player && $player->isOnline()){
	CameraInstruction::clear()->send($player);
}

• Multi

use muqsit\libcamera\libcamera;
use muqsit\libcamera\CameraInstruction;
use pocketmine\network\mcpe\protocol\types\camera\CameraFadeInstructionColor;
use pocketmine\network\mcpe\protocol\types\camera\CameraFadeInstructionTime;
use pocketmine\math\Vector3;
use pocketmine\player\Player;

// ...
if($player instanceof Player && $player->isOnline()){
	CameraInstruction::multi(
		CameraInstruction::target(
			targetCenterOffset: Vector3::zero(),
			actorUniqueId: $player->getId()
		),
		CameraInstruction::fade(
			color: new CameraFadeInstructionColor((float)$r,(float)$g,(float)$b),
			time: new CameraFadeInstructionTime((float)$fadeInTime,(float)$stayTime,(float)$fadeOutTime)
		)
	)->send($player);
}

Roadmap

At the moment, there are a few improvements that can be/or are being worked on. Here is a list of some of those improvements:

• Allow registering new camera presets
