Tasks

Creating a Simple Plugin Task

We'll take our last plugin and adding a simple task to it that tells the user when 10 seconds has past.

First, go to your "Main.php" folder and create a new folder called "tasks".

Create a new file called "MyTask.php".

And put those contents inside it.

MyTask.php
<?php // As always when you start a PHP file

namespace YourPluginName\YourName\tasks; // Use the same namespace as in your first file but add a \tasks who symbolise that this file is in the subfolder "tasks"

use pocketmine\scheduler\Task; // This is the class that your task will extends to be a plugin task
use ExampleName\Main; // This will allow us to use our main class. It is a required argument for a plugin task.
            
class MyTask extends Task { // Remember that your task must have the same name as your file !

// First we need a __construct function which is used when you create a class to set default variables, ect...
    public function __construct(Main $main, string $playername) { // The arguments you define here depends on what do you want to do exept for your base.
       $this->main = $main; //You can retrieve your main class at anytime and use it's methods on your class by using $this->getOwner()
       $this->playername = $playername; // So we can retreive the player for later.
    }

// Then we'll create an onRun funtion wich will be called when the time has past to the execution of the task
    public function onRun() {
        $player = $this->getOwner()->getServer()->getPlayer($this->playername()); // This retreive the main class with $this->getOwner() then asks the server for the player with the name $this->playername
        if($player instanceof Player) { // Basicly checks if the player we retreive is online.
            $player->sendMessage("10 seconds has past!"); // Sends him a message !
        }
    }
// Then we create a getOwner function to return the Main class
    public function getOwner() : Main {
        return $this->main;
    }
}

That's it you created a task ! Now we'll see how to execute it.

First we will make it execute 1 time, but delayed

In your main class, where you did your "example" command.

Main.php

    $task = new tasks\MyTask($this, $sender->getName()); // Create the new class Task by calling
    $this->getScheduler()->scheduleDelayedTask($task, 10*20); // Counted in ticks (1 second = 20 ticks)

So the player will receive a message 10 seconds after he executed the command /example !

But now, what if we want the player to receive a message each 10 seconds?

Well, there's a special function for that! We don't even need to change the task!

Main.php

    $task = new tasks\MyTask($this, $sender->getName()); // Create the new class Task by calling
    $this->getScheduler()->scheduleRepeatingTask($task, 10*20); // Counted in ticks (1 second = 20 ticks)
