send BossBar

What is the format for this?

 

You must use a custom API for this.
PocketEssential have created an API, which you can find here: https://github.com/PocketEssential/BossBarAPI

PHP:

// First you"ll need this
use PocketEssential\BossBarAPI\BossBarAPI;

// You can also do:

$BossBarAPI = BossBarAPI::getInstance();

Sending bossbar

PHP:

$message = "This is a BossBar message";

$BossBarAPI->setBarMessage($message);

/*
 Player should an instance of a PLAYER, Just foreach loop all the online players; etc
 */

$BossBarAPI->sendBossBar($player);


 

Nop you can send packets manually too

 

How to that?

 

Thanks ill try it

 

It is possible to send packets, but I think he was trying to give OP a faster way.

For anyone that wanted to know how to do this manually and create an API themself, here's how.

Spoiler: Code to create the BossBar

PHP:

use pocketmine\item\Item;
use pocketmine\network\protocol\AddPlayerPacket;
use sys\jordan\utils\BossEventPacket;
use pocketmine\network\protocol\MovePlayerPacket;
use pocketmine\network\protocol\SetEntityDataPacket;
use pocketmine\Player;
use pocketmine\network\protocol\RemoveEntityPacket;
use pocketmine\Server;
use pocketmine\network\protocol\AddEntityPacket;
use pocketmine\entity\Entity;
use pocketmine\utils\UUID;

class BossBar {

    private $plugin;

    public function __construct(Main $plugin){
        $this->plugin = $plugin;
    }

    public function addBar(array $players = null){
        if(empty($players)){
            $players = $this->plugin->getPlayers();
        }
        $eid = Entity::$entityCount++;
        $aepkt = new AddEntityPacket();
        $aepkt->metadata = [Entity::DATA_LEAD_HOLDER => [Entity::DATA_TYPE_LONG, -1], Entity::DATA_FLAG_SILENT => [Entity::DATA_TYPE_BYTE, 1], Entity::DATA_SCALE => [Entity::DATA_TYPE_FLOAT, 0],
            Entity::DATA_BOUNDING_BOX_WIDTH => [Entity::DATA_TYPE_FLOAT, 0], Entity::DATA_BOUNDING_BOX_HEIGHT => [Entity::DATA_TYPE_FLOAT, 0]];
        $aepkt->eid = Entity::$entityCount++;
        $aepkt->type = 52;
        $aepkt->yaw = 0;
        $aepkt->pitch = 0;
        foreach($players as $player){
            $ppkt = clone $aepkt;
            $ppkt->x = $player->x;
            $ppkt->y = $player->y;
            $ppkt->z = $player->z;
            $player->dataPacket($ppkt);
        }
        $pk = new BossEventPacket();
        $pk->state = 0;
        $pk->eid = Entity::$entityCount++;
        Server::getInstance()->broadcastPacket($players, $pk);
        return $eid;
    }


    public function setTitle(int $eid, string $string){
        $players = $this->plugin->getServer()->getOnlinePlayers();
        $pk = new SetEntityDataPacket();
        $pk->metadata = [Entity::DATA_NAMETAG => [Entity::DATA_TYPE_STRING, $string]];
        $pk->eid = $eid;
        Server::getInstance()->broadcastPacket($players, $pk);
        $pkt = new BossEventPacket();
        $pkt->eid = $eid;
        $pkt->state = 500;
        Server::getInstance()->broadcastPacket($players, $pkt);

    }
}
// You should probably use a task also. I will post this in the resources forum later.
[/SPOILER]

 

But nobody else can use this method, because they don't have a BossEventPacket class. Also, your class paths aren't compatible with the current master branch of PMMP.

 

I really should've thought about that. Silly me, editing now and I will include BossEventPacket. Why isn't it compatible though?

 

There were some changes in PMMP that involves packets. The correct path for AddPlayerPacket, for example, would be: pocketmine\network\mcpe\protocol\AddPlayerPacket.

 

Wow... any reasons why they changed the path?

 

I've made a thread on resources. Currently awaiting approval from a moderator

 

I assume it was because the former was a mess. This way network classes can be separated, since there are network classes for mcpe protocol, and for the raklib/etc. stuff. It's neater now, but there may be other reasons for the change I don't know about.
