Callbacktask

What is callback task?

also I want to learn how to use onRun current tick

https://github.com/PocketMine/Pocke.../src/pocketmine/scheduler/ServerScheduler.php
But callback task is deprecated

Never use CallBackTask. It is for lazy people who don't want to create a sperate class.

But pocketmine uses this

PocketMine no longer uses it. Tasks that don't extend PluginTask will not be cancelled when the plugin is disabled, so /reload will result in the task being run twice
