Call to undefined method HG\Main::sendTip()

i dont know what to do it only works with sendMessage() and broadcastMessage()

You can only send a Tip to a player. Also it is an event, use

PHP:

public function onJoin(PlayerJoinEvent $event){
$player = $event->getPlayer();
$player->sendTip("Your-Tip");
}

Of course you have to use/import PlayerJoinEvent.

but its a CallBackTaskk

Where is it a CallBackTask? Did you even learn PHP and the PM API?

this..

PHP:

$this->getServer()->getScheduler()->scheduleRepeatingTask(new CallbackTask([$this,"onJoin"]),10);

and this...

PHP:

public function onJoin() {
    $p = $this->getServer()->getOnlinePlayers();
    $p->sendTip("Welcome To Savion's Test Server!!!");
       

}

i just started to learn .-.

Wat
$p will become an array.
And you are trying to send it to everyone?
And who do you want to send that message to? Why did you use a repeating task?
