How to get a Server Instance in AsyncTasks in API 4.0.0 without modifying the Task constructor

As of recent API changes in PocketMine-MP, the onCompletion() function of AsyncTasks does no longer receive a Server Instance.
e.g.:

Code:

public function onCompletion(Server $server) : void
{
}

changed to

Code:

public function onCompletion() : void
{
}

Now: How do we get the server instance again WITHOUT having to try to serialize it in the constructor (which sometime is impossible)?
The answer is very simple: Create a direct call to the static getInstance() function of the Server class.
To use this, make sure you have

Code:

use pocketmine\Server;

in you asynctask's imports.
Now, to regain your $server variable,
just create the direct call to the Server::getInstance() function in your onCompletion() function.
So the code changed from:

Code:

public function onCompletion(Server $server) : void
{
}

to:

Code:

public function onCompletion() : void
{
  $server = Server::getInstance();
}

Small notice for staff:
It might be a good idea to move this in the low quality section as it
is not relevant for a lot of people...

 

This is very easy and I do not think it would help, but if anyone has that issue, the class for Server is pocketmine\Server. This means you have to add use pocketmine\Server; in the imported classes.

 

I agree. I just thought the developemnt section might be the wrong place to post this since this is a small fix description rather than a request. I designed this with the hope that it will save a bit of someone's time, but if you think a how to get a plugin's instance guide would be more usefull I could do that aswell, of course.
I will post the next guide directly in the facepalm section, just to make sure.
