Run function in background

I need to run one of my functions in the background because it brings to much lagg to my server. I found this: http://php.net/manual/de/gearmanclient.addtaskbackground.php

But I don't know how to set it for one function

 

Not sure if gearman will work for pocketmine. Show us the function. If you are directly changing variables in the main thread it will cause issues.

 

I run a command (/info). This will start the function getInfo.

PHP:

public function getInfo(/*some variables*/) {
//$info = from website
return $info;
}

 

Use AsyncTask.

 

Can u give me an example? I need to run the function getInfo in there

 

Can you send us the function?

 

PHP:

public function getInfo($ip, $port, $timeout = 10) {
if ($ip and $port and $timeout)
{
        $minecraft = @fsockopen("$ip", $port, $timeout);
}
if($minecraft)
{
$status = "online";
} else {
$status = "offline";
}
}

 

Create a class "InfoTask" and extend it with \pocketmine\scheduler\AsyncTask.

Create a public function "onRun()" in the class.

PHP:


private $ip, $port, $timeout;
public function __construct($ip, $port, $timeout = 10){
    $this->ip = $ip;
    $this->port = $port;
    $this->timeout = $timeout;
}

public function onRun(){
    $minecraft = @fsockopen($this->ip, $this->port, $this->timeout);
    $status = $minecraft ? "online" : "offline";
    $this->setResult($status);
}

public function onCompletion(Server $server){
    $server->getLogger()->notice("
        Background task has finished. The output was:
    ".$this->getResult());
}


Call InfoTask from another class:

PHP:

//$ip = ...
//$port = ...
//$timeout = 10
Server::getInstance()->getScheduler()->scheduleAsyncTask(new InfoTask($ip, $port, $timeout));


You can refer to the docs for function descriptions.

 

Error

Code:

onCompletion() must be an instance of MyPlugin\Server,

 

Add use pocketmine\Server;

 

And how can I get the result?
"Server::getInstance()->getScheduler()->scheduleAsyncTask(new InfoTask($ip, $port, $timeout));" only starts it

 

add another parameter to construct it with that will allow it to access your plugin's main class

 

What do u mean? Example? In what file/class?

 

It's terrible idea to pass objects from main thread to another.

You want to send this data to player that issued the command, right? So pass player name to AsyncTask and do this

PHP:

onCompletation(Server $server) {
   if(($player = $server->getPlayer($this->issuer)) {
      $player->sendMessage($this->getResult());
   }
}


 

No. I have another function in my main thread where I start the task. There I want to return the status

 

What is the best way to do that?

 

I tried to get the result in another file. But it gives me an error

PHP:

$status = $this->getServer()->getScheduler()->scheduleAsyncTask(new StatusTask($ip, $port, $timeout));
return $status->getResult();

//error:  Call to a member function getResult() on null

 

that's because ScheduleAsyncTask returns void

 

And how can I get it than?

 

PHP:

private $ip, $port, $timeout, $server, $status;
public function __construct(Server $server, $ip, $port, $timeout = 10){
    $this->ip = $ip;
    $this->port = $port;
    $this->timeout = $timeout;
    $this->server = $server;
}

public function onRun(){
    $minecraft = @fsockopen($this->ip, $this->port, $this->timeout);
    $this->status = $minecraft == true ? "online" : "offline";
}

public function onCompletion(Server $server){
    $server->getLogger()->notice("
        Background task has finished. The output was:
    ".$this->status);
    $server->getPluginManager()->getPlugin->("pluginName")->result = $this->status;
}
